Hi everyone! I have to implement a GUI for PocketPCs, which includes a 3D-window, listboxes, buttons and sliders. For the 3D-part I decided to use OpenGL ES, and MFC for the other stuff. I know that there are some tutorials out there on how to include OpenGL in MFC, but all of them seem to use functionality, which is not available for PocketPCs (e.g. PIXELFORMATDESCRIPTOR, or wgl*-calls). So my questions would be: Has anybody successfully integrated OpenGL ES in an MFC application and can provide me with a small code example or point me to a tutorial, or does anybody know if there is a better way to tackle that problem. Thanks in advance! Adrian
