wxWidgets Debug Alert: windows.cpp(3734): assert "wclass" failed in wxWindows::MSWCreate()

Hi Everyone,

Actually I working on a projet SLAM and I use the MRPT solution  with Kinect. 

I have follow the differents steps for implementing the mrpt soft with Kinect.

No errors throughout tutorial but now I have an error when I try to execute the execution solution generated by MRP.sln :

wxWidgets Debug Alert: windows.cpp(3734): assert "wclass" failed in wxWindows::MSWCreate(): failed to register window class? Do you want to stop the program?...

Have you any idea to where is the problem? 

I worked on Windows XP OS 32bits, and my IDE is VC++ 08.

Thanks for your answers 

Cheers,
