Hello, I was hoping that someone could help me with a problem I have. How can I retrieve the size of the total local video memory? I can't seem to find any api calls that do it. The directX calls I found return the local + nonlocal memory. Where does windows get this information from? When you go to display properties/settings/advanced/adapter, it tells you the memory size and vendor, that's exactly what I need to do. Any help is appreciated tremendously. Thanks.
Windows actually pulls all of that info out of the registers. I was just looking at the registers and found info about my video card but no where does it list how much vram that I have. Did you already look through msdn? If not its worth a try.
Look up the Win32 Registry functions such as RegQueryValueEx().

Thanks for the suggestions, but I still couldn't get the video memory from the registry. Also, from what master5001 said, I couldn't depend on that information being in the registry. I had already searched MSDN, but never found anything. Any other ideas?
It seems to me that the dx diagnostic tool determines the amount of video memory by filling it, and seeing how much memory it filled. Maybe you could do something like that.
Try this
Code:
MEMORYSTATUS mem_stat;
GlobalMemoryStatus( &mem_stat );
/*
typedef struct _MEMORYSTATUS { // mst
DWORD dwLength; // sizeof(MEMORYSTATUS)
DWORD dwMemoryLoad; // percent of memory in use
DWORD dwTotalPhys; // bytes of physical memory
DWORD dwAvailPhys; // free physical memory bytes
DWORD dwTotalPageFile; // bytes of paging file
DWORD dwAvailPageFile; // free bytes of paging file
DWORD dwTotalVirtual; // user bytes of address space
DWORD dwAvailVirtual; // free user bytes
} MEMORYSTATUS, *LPMEMORYSTATUS;
