Hello, all! Does somebody have some experience for the issue of the following and could kindly tell me some solutions: Pass a HWND(Handle) of a TForm in Cppbuilder to a DLL generated by MS Visual C++ where it makes all drawing with OpenGL lib. I got a problem as: During sending drawings to a view generated in MS Visual C++ with the HWND, in certain moment, the DLL lost the connection with HWND without any error. In fact, I cannot see any changes any more in the view. I was told that I had to setup some properties such as WS_CLIPCHILDREN, WS_CLIPSIBLINGS etc., in short, I must properly setup OPENGL for the HWND. But I have looked into the style of the form(by debug), its default style already contains all those style. Thank you in advances! Siping <szhn at lvd.be>
