render while not focused

Isolate the Render method out of the WindowProc function?
If focused or not, if you call Render it has to render, regardles if it is active or not. That is a fact.

The horror case:
WindowProc(...)
switch (wm_message)
case WM_PAINT: open device, render, close device; ScreenFlip(); break;
..........

make it better:
WM_PAINT: render();break;

Try to call Render() from anywhere else, or from another window! It has to work.

I believe what you seek is "Timer". You can bind a "function" to a timer, let us say your window shall update, regardless active or not, every 250 miliseconds, that is 4x times a second. Check the "SetTimer" function and some examples. Even if your window might get inactive it will be rendered by the timer, if the MESSAGE connected to the timer event would call Render!

yeah im doing that and i checked it is calling it but nothing is showing up.
i figure the problem has got to do with Present()?

Hm, you might call Present with (NULL, NULL, NULL, NULL) since every parameter is NULL directx takes the default. Since the window that you would like to render isn't active anymore it also isn't default. Try to pass the HWND from your render window to Present (See help on parameters) and perhaps you should transfer the client rectange (GetClientRect or GetWindowRect) too?

I hope it will help.

Thanks for the idea man but unfortunately it didnt work, doesnt matter though, i already had started again using GDI completely....
