DirectX and WPF

I am trying to develop an application where the UI part is designed by WPF and the engine is developed using C++. I am trying to render a scene using DirectX in native code by getting the window's handle from WPF using WindowsFormsHost method.

Though i do not get any error, no image renders on the screen.

As far as the handle is concerned, I dont see a problem because when i render th开发者_StackOverflow中文版e scene using OpenGL using the same handle in native code, it works properly.

As far as the initialization part and rendering part is concerned, I dont see a problem because the same part of code works fine in a separate Win32 project.

What might be the cause of this problem? The version of DirectX being used is DirectX10 and OS used is Vista.

Thanks in advance.

I think your problem might be caused by the fact that WPF is also using DirectX to render the window. OpenGL probably gets around the issue just by being different.

If you want to render DirectX in a WPF app, have a look at using D3DImage.
