I just noticed it now in your previous response, but you said they have interop WPF dlls that are working? Why don't you just use those? Are those written in C# or C++? If they are written in C#, you can view the exact code by using ILSpy, .NET Reflector, etc. If they are written in C++, you can view the DLL exports easily using the dumpbin utility that comes with Visual Studio.
Hi, You're rather trying to do something that will break WPF! WPF is rendered using DirectX. The whole thing, there is just a window wrapper for win32 environment. You cannot do anything by passing it an WM_PAINT message.
Here comes the fix. Set up a winforms host inside your app xaml. Put a label control (winforms equivalent of STATIC) inside the host . Set the text to empty. get it's HWND by getting its Handle property and pass it to your native library that does OpenGL stuff through P/Invoke.
Here is a MSDN Walkthrough to guide you. Just replace that MaskedTextBox code with a Label.
I just moved to a new company. And they use this seemingly cool ORM: IdeaBlade, will let the developer do Linq2SQL on the client (Silverlight) side. There are performance issue though... Haven't work with real data yet (it's big) but just the ORM seems to have some down time (due to initialization and query parsing) I wonder did anyone here used IdeaBlade (DevForce)? is it good? How does it compare to WCFDataService?
