DLL Problem by jeickmann

//this is the code from the exe (in main()): class Tmp : public WindowingEventHandler { public:     void DrawFrame();     RenderableSurface * r; }; void Tmp::DrawFrame() {     unsigned char red = 0;     glClearColor(((float)red/255.0f), 0.0f, 0.0f, 1.0f);     glClear(GL_COLOR_BUFFER_BIT);     r->swap(); } Windowing * w = loader.extractObject("getWindowing"); if(w != 0) {     Tmp handler;        handler.r = w->createWindow(800, 600, false, &handler);         cout << "YUP" << endl; } //and this is the stuff from the dll: BOOL MFCGLApp::OnIdle(LONG lCount) {     handler->DrawFrame();     return TRUE; }
