Query graphics card

[Mike Harnad]

I have a need to obtain information about the installed graphics card. I wrote a small utility that walks through the registry and grabs the card type, driver name and version. Is there a more direct way to obtain this information? An API call perhaps?

PS...I don't want to use OpenGL or DirectX functions to do this.

you can use:

::EnumDisplayDevices(..) (http://msdn.microsoft.com/library/default.asp?url=/library/en-us/gdi/devcons_2303.asp)
::EnumDisplaySettings(..) (http://msdn.microsoft.com/library/default.asp?url=/library/en-us/gdi/devcons_84oj.asp)


look at this sample code:


typedef BOOL (_stdcall *tEnumDisplayDevicesA)(LPCTSTR,DWORD,PDISPLAY_DEVICE,DWORD);

tEnumDisplayDevicesA pEnumDisplayDevicesA = 0;
HINSTANCE handle = ::LoadLibrary("User32.dll");
if ( handle )
pEnumDisplayDevicesA = (tEnumDisplayDevicesA)::GetProcAddress(handle, "EnumDisplayDevicesA");
if ( pEnumDisplayDevicesA )
{
DISPLAY_DEVICE DD={0};
DD.cb = sizeof( DISPLAY_DEVICE );
pEnumDisplayDevicesA(0,0,&DD,0);


DEVMODE DM={0};
DM.dmDriverExtra = sizeof(DEVMODE);
::EnumDisplaySettings((const char*)DD.DeviceName,ENUM_REGISTRY_SETTINGS,&DM);
}
if ( handle )
::FreeLibrary(handle);


hope it helps.

Cheers

Thanks for the reply. However, it looks like those functions won't provide what I'm looking for.
