ok, i''ve got some code which mostly works... i''ll post it up for everyone. any feedback on making it better would be nice =) If ya have questions or anything just post em up! //=========================== // processing Alt+Enter //=========================== In my app, i''m using directinput, so in your dinput code do something like //------ DIDEVICEOBJECTDATA keybuf[10]; DWORD dwitems = 10; app.dinput.keyboard->GetDeviceData(sizeof(DIDEVICEOBJECTDATA), keybuf, &dwitems, 0); //Loop through data and process them for(DWORD i = 0; i < dwitems; i++) ProcessKey(keybuf); //------ //------------------------------------------ void ProcessKey(DIDEVICEOBJECTDATA key) { ... if((key.dwOfs == DIK_LMENU) // (key.dwOfs == DIK_RMENU)) { app.keyboard.keystates.alt = 1 && (key.dwData & 0x80); return; } if(app.keyboard.keystates.alt) { if(key.dwOfs == DIK_RETURN) { app.screen.fullscreen = !app.screen.fullscreen; SetDisplay(); } } ... } //=========================== // two funcs to change res //=========================== //------------------------------------------ bool ChangeResolution(bool reset) { DWORD dwRet; DEVMODE devMode; devMode.dmFields = DM_BITSPERPEL / DM_PELSWIDTH / DM_PELSHEIGHT; //if exiting set it back how it was! if(reset) { devMode.dmBitsPerPel = app.screen.original.bitdepth; devMode.dmPelsWidth = app.screen.original.width; devMode.dmPelsHeight = app.screen.original.height; dwRet = ChangeDisplaySettings(&devMode, CDS_RESET); } else { devMode.dmBitsPerPel = app.screen.current.bitdepth; //original res if(!app.screen.fullscreen) { devMode.dmPelsWidth = app.screen.original.width; devMode.dmPelsHeight = app.screen.original.height; } //Fullscreen else { devMode.dmPelsWidth = app.screen.current.width; devMode.dmPelsHeight = app.screen.current.height; } DEVMODE CurrDevMode; EnumDisplaySettings(NULL, ENUM_CURRENT_SETTINGS, &CurrDevMode); return ChangeDisplaySettings(&devMode, CDS_FULLSCREEN); } //------------------------------------------ void SetDisplay(void) { HWND hWnd; if(app.hWnd != NULL) DestroyWindow(app.hWnd); if(!ChangeResolution(false)) return; if(app.screen.fullscreen) { hWnd = CreateWindowEx(WS_EX_APPWINDOW, szAppName, szAppName, WS_POPUP / WS_CLIPSIBLINGS, 0, 0, app.screen.current.width, app.screen.current.height, NULL, NULL, app.hInstance, NULL); } else { //compensate for frame & caption LONG h = GetSystemMetrics(SM_CYCAPTION) + GetSystemMetrics(SM_CXDLGFRAME) * 2 + app.screen.current.height; LONG w = GetSystemMetrics(SM_CXDLGFRAME) * 2 + app.screen.current.width; hWnd = CreateWindowEx(WS_EX_APPWINDOW, szAppName, szAppName, WS_BORDER / WS_DLGFRAME / WS_CLIPSIBLINGS / WS_MAXIMIZEBOX / WS_MINIMIZEBOX / WS_SYSMENU, 50, 50, w, h, NULL, NULL, app.hInstance, NULL); } if(!hWnd) PostQuitMessage(1); ShowWindow(hWnd, SW_SHOWNORMAL); SetForegroundWindow(hWnd); } //=========================== // In Winmain just call SetDisplay() // after registering your wndclass //=========================== WinMain... { ... //register wndclass SetDisplay(); ... }; //=========================== // In WndProc do something // similar //=========================== WndProc... { ... WM_CREATE: { ... InitDInput <-- if using direct input, init here GetDC... SetupPixelFormat... wglCreateContext... wglMakeCurrent... LoadTextures... <--- Need to reload textures after recreating the window InitGL... <-- setup things such as clear color and whatnot ... } WM_DESTROY: { ... wglMakeCurrent(NULL, NULL) wglDeleteContext... ReleaseDC... TermDInput <-- if using direct input, kill it here ... } ... }

The new article on GameDev should help somewhat as well Just thought I''d state the overly obvious.

Going from Exclusive mode to Windowed mode in DD isn''t done the same as switching from full to windowed in OpenGL, so unless using DD that article won''t help!
