Is there any way to detect - through the Direct3D API - Direct3D applications running in full-screen mode?
SHQueryUserNotificationState, which can indicate such applicat
I found how to detect full-screen Direct3D and OpenGL (for example Minecraft) applications.
Call IDirectDraw7::TestCooperativeLevel(). This function returns DDERR_EXCLUSIVEMODEALREADYSET
if active full-screen Direct3D application is running or if user session is not active (Win+L, Alt+Ctrl+Del, Fast User Switching, etc).
Note: Call DirectDrawCreateEx
with DDCREATE_EMULATIONONLY
. This dramatically reduces resources usage by IDirectDraw7.
I have tested this method only in Windows 7 SP1 x64 with 1 display.
BTW SHQueryUserNotificationState()
returns QUNS_BUSY
instead of QUNS_RUNNING_D3D_FULL_SCREEN
for full-screen games. Strange...
Try 'IDirect3DDevice9::GetDisplayMode':
http://msdn.microsoft.com/en-us/library/bb174387%28VS.85%29.aspx
HRESULT GetDisplayMode(
UINT iSwapChain,
D3DDISPLAYMODE * pMode
);
Parameters:
iSwapChain[in]
An unsigned integer specifying the swap chain.
pMode[out]
Pointer to a D3DDISPLAYMODE structure containing data about the
display mode of the adapter. As opposed to the display mode of the device, which may not be active if the device does not own full-screen mode.
