Date maskedEdit with watermark doesn't update on invalid date


I'm trying to use the TextBoxWatermarkExtender with MaskedEditExtender/Validator and have found a bug (I think).

In the textbox I enter an invalid date such as 55-55-5555 and exits the textbox. I would then expect the watermark to be shown, but it doesn't. Instead the prompchar is shown (like __-__-____).

If I simply give focus to the textbox and then another control, the watermark is shown.

Is there a workaround such as manually force the TextBoxWatermarkExtender to update.

I'm not the best with javascript, I tried to call focus() and blur() on the textbox in the textbox's onBlur event using window.setTimeout. This works in Firefox, but not IE8, also there has to be a better way I think :-)

            <asp:TextBox ID="TextBox5" runat="server" MaxLength="1" onBlur=""/>
            <asp:ImageButton ID="ImgBntCalc" runat="server" ImageUrl="~/images/Calendar_scheduleHS.png" CausesValidation="False" />

        <ajaxToolkit:TextBoxWatermarkExtender ID="TBWE2" run

Inkcanvas Recognizing and replacing shapes

Looking for some sample code or guidance for doing the following below. Thought this would be somewhat common.....

1) Using InkCanvas to allow drawing of shapes
2) Forcing the inkcanvas/inkanalyzer to limit its recognition to specific shapes (ellipses, circle, rectangle) 
3) Replacing the drawn and recognized shape strokes with a proper shape control that has a textbpx inside the shape

(Using 2010)


Gesture recognition on InkCanvas on XP



I'm currently developing a small app in WPF that requires gesture recognition, so I ended up using the InkCanvas. Everything works just fine on my desktop and laptop (running windows 7) but the app must run in another computer (an Asus Eee Top running windows XP). I've read that I had to install the Tablet PC SDK and the Tablet PC Recognition Pack, but I'm unable to install the Recognition pack because it complains about an unsuported OS: apparently it only suports XP up to Service pack 2, and I'm running SP3.

Are there any other alternatives?

Adding watermark or text to images on uploading or displaying


Is there a way to process images once uploaded to my asp.net site, to put a watermark or some text across the image to copyright the images? I would like to do this server-side if possible.

The other option I have discovered here (http://wpglamour.com/how-to-watermark-all-your-uploaded-images/) would be to store the images as they are on the server, but to manipulate the display so it appears the image is watermarked . However, this solution is in PHP. Does anyone know a good PHP to VB.NET translator?! Or does anyone have a good suggested link, idea or code? Or can I add PHP to my ASP.NET site?

Multithreading Dynamic Shape Drawing on InkCanvas?


note: Multithreading code adapted from here http://elegantcode.com/2009/07/03/wpf-multithreading-using-the-backgroundworker-and-reporting-the-progress-to-the-ui/


The Problem:  The line is not rendered consistently, only on the mouseleftup event.

Scenario: 1. Michael clicks the Line button on the toolbar

2. Michael brings the mouse over the ink canvas and clicks the left mouse button

3. While moving the mouse to the right to draw a line, he notices that nothing shows up.

4. On releasing the mouses left button, the line finally renders correctly.

I realize that i most likely need to multithread to accomplish this.

To begin i have  a basic WPF setup, menu bars, borders, toolbars, and i have an ink canvas. The goal of this project is to familiarize myself with image editing and drawing programs. I created a basic Line2D class.


 public class Line2D
  BackgroundWorker worker;

  MainWindow window;
  InkCanvas canvas;
  Line lineToBuild;
  public Line2D(InkCanvas curren
