Vinod,

I got this from my team. Please verify you are doing this:

Make sure your customer also overrides Deactivate and removes the event handler he’s added. A new task provider will be created and activated each time his control gets selected.

Here is another block of code I was sent by a team member.

Something slightly tighter is – I don’t know if they’re writing against the old or new Model, hopefully this should work on both.

   private void service_ModelChanged(object sender, ModelChangedEventArgs e) {
       // Get the removed Items from window
       foreach (ModelItem mi in = e.ItemsRemoved) {
           // Get the name of the control deleted
 if (typeof(MyControl).IsAssignableFrom(mi.ItemType)) {
           // Write the clean up code
}
       }

Cheers, Karl

Hi Karl,
thanks for the reply. but I can not check for a particular type of control. there
are any custom controls. I have one doubt , can I track the Ctrl + X event here. I mean
I want to know whether ther the user has pressed Ctrl-X or Delete button. In
e.ItemsRemoved I get the control in both the cases.
thanks,
vinod

You'll need to retemplate the Expander control, add a second expander button to execute the required code.

Retemplating is not hard once you understand WPF. There are plenty of examples here on Code Project for retemplating controls.

An easier way to do this is to use a Grid with two columns, both of which are the same size. Don't set any size info in your listboxes, just assign them to the appropriate grid column and let the grid take care of laying your items out.

Visual Studio XAML Editor Hotfix

For you WPF/Silverlight users that experience the frequent crashes of Visual Studio while editing XAML…

I indirectly came across this issue filed on Connect:

Frequent "Microsoft Visual Studio is Busy" hangs after installing VS2008 SP1[^]

I had been using the March hotfix, which diminished the frequency of crashes but didn’t eliminate them.

Turns out there’s a May hotfix:

KB963035 - VS2008 SP1 sometimes hangs irretrievably after WPF Designer[^]

Jury’s still out, but I haven’t had a crash yet in two days….I’m going to keep hammering on it with my fingers crossed…

Where did you place that button? Is it in Silverlight User Control or ASP.NET?

Please check this HTML Bridge[^] if you like to interact between Managed Code of Silverlight and Javascript.

Hope it helps.

You shouldn't mess with that as it's set to what the operating system says it should be. That being said...

The only thing I know to suggest is to get expression blend and scrape the window class template from it, and work from that. You'll probably have to write a class that inherits Window, and add an attached property.

Like John stated - the OS handles that.

If you rip the Window template using blend, you still won't be able to change the
title bar.

If you must provide a custom title bar, you can use a Window without a title bar
and provide your own. For example, see Nish's article:

WPF tip : Using a custom title bar[^]

Note you won't get any of the visual cues provided by the OS Smile | :)

tv tuner and directShow

Does anybody have any insight on audio streaming through a tv tuner in a vb app? I'm using a directshow2005.dll. I have the video end of it working fine, but the audio does not work. Is there a way to check the graphBuilder or the assigned pins? Or does anybody have any better suggestions? Maybe an updated dll or or completely different one? I was reading some other forums and this seems to truly be a tough topic in everything before 3.5 .net framework.
