WPF Controls In PaletteSet

Anonymous — Wed, 30 Jul 2008 22:04:34 GMT

I'm having some issues w/ VS2008 and AutoCAD:
• When I run code using VS2008 in debug works flawlessly.
• When NETLOAD module independently of VS2008 => Crash and burn. 😞
Can someone please help?
internal class paletteSetLibrary
{
// {31258470-74A3-4b73-AF2F-EB5342684526}
private static Guid PaletteSetId = new Guid("31258470-74A3-4b73-AF2F-EB5342684526");

public PaletteSet paletteSet { get; set; }
public void Initialize()
{
paletteSet = new PaletteSet("Library", PaletteSetId)
{
Visible = true,
Style = PaletteSetStyles.Snappable | PaletteSetStyles.ShowAutoHideButton,
WindowState = FormWindowState.Normal,
KeepFocus = true
};
var libraryViewer = new LibraryViewer();

var elementHost = new ElementHost(){Dock = DockStyle.Fill};
elementHost.Child = libraryViewer;

paletteSet.Add("Details", elementHost);
}

}

I've run into a similar problem, which I'm not sure can be fixed. (Don't take my word for it though).

The reasoning is that WPF doesn't allow you to update it with a thread other than the one that it was created with. I had better success using a form to host my controls, but I'd still get crashes.

If you find a way to get past it, I'd be very excited to hear!! 🙂

From your Initialize() method, check the value of the DocumentManager's IsApplicationContext property and
tell us what it returns.

Also what release of AutoCAD is this?

Tony,

It looks like IsApplicationContext=false. I've posted a simplified version of my solution if you would like to have a closer look. I am using ACA2008 SP1. Like I said, all runs well while debugging.

Thanks for your help, I can't even count the number of times your posts have saved my a@#.

Thanks again,

Try using DocumentManager.ExecuteInApplicationContext
to run your Initialize() method in the application context.

You would use something like this:

using Acad = Autodesk.AutoCAD.ApplicationServices.Application;

public class MyApplication : IExtensionApplication
{
public void Initialize()
{
Acad.DocumentManager.ExecuteInApplicationContext(
delegate( object unused )
{

// TODO: call the method that creates your paletteset

}, null
);
}

public void Terminate{}
}

Another option, if your paletteSet is created by the
handler of a registered command, is to include the
CommandFlags.Session flag to the CommandMethod
attribute.

Tony,

I tried both ExecuteInApplicationContextCallback & CommandFlags.Session from a CommandMethod to no avail. I will be plowing ahead until I get it to work. If it works in Debug there has to be a way to get it to work outside of VS2008.

Here are three ways to code WPF that may or may not be of any help depending on what your doing.

I used Expression Blend 2.5 June Preview to do the gradient and buttons.

I get an exception when using the commands

System.InvalidOperationException: The calling thread cannot access this object because a different thread owns it.

Others may be able to help if they had a reproducible case,
but unfortunately the project you uploaded is not buildable
because it references assemblies not included.

If you can produce a simple, scaled down case where the
error occurs, we may be able to help solve your problem.

When ever your window is mode less, then don't forget to lock the acad document you are dealing with.

using (DocumentLock docLock = doc.LockDocument())
{
// Your code...
}

I know it's been a while since this initial post was created, but I thought I'd post what worked for me since I was experiencing the same issue.

I've created my project in VS2008, and I'm using a WPF User Control for my interface. When debugging, everything would work perfectly. If I would launch AutoCad and load the .dll without going through the debugger, I would get the basic JIT exception. After troubleshooting, it appeared that the rendering of the WPF control is what was throwing the exception. I read through this post and tried the suggested ideas. My IsApplicationContext was 'False' both in and out of debug mode. The thing that fixed it for me was the CommandFlags.Session. Once I added this to my method, everything worked perfectly. I don't understand why this would work in debug only, but it saved my day!

If you are interested, I've attached my method.

The reason it works with the session command flag is because the WPF control
needs to be created in the session context, rather than in the document
context.
