Okay, I was going to write a program for fun (and maybe, probably not practical use) that sees how much Video Memory you have, and how much your using. My friend sugessted DirectDraw for this task.
I googled video memory programming, and came up with this link. The first answer says this:
From what I've read you need ddraw.h and ddraw.dll (both of which I have)....
Total amount of display memory on the device, in bytes, minus memory reserved for the primary surface and any private data structures reserved by the driver. (This value is the same as the total video memory reported by the IDirectDraw7::GetAvailableVidMem method.)
Free display memory. This value equals the value in dwVidMemTotal, minus any memory currently allocated by the application for surfaces. Unlike the GetAvailableVidMem method, which reports the memory available for a particular type of surface (such as a texture), this value reflects the memory available for any type of surface.
From MSDN (*dodges flames*) it says that IDirectDrawVideo::GetCaps (HRESULT GetCaps(DDCAPS *pCaps);) can get this information also.
Now, onto my question. Should I use one of these two methods or possibly another one? And is there a good DirectDraw tutorial that teaches use of one of the methods?
I found this. Good tutorial, but it doesn't teach GetCaps or dwVidMemTotal/dwVidMemFree. If someone could point me in the right direction, I would be most grateful.
