Desktop Window Manager API

Desktop composition is performed by the Desktop Window Manager (DWM). Through desktop composition, DWM enables visual effects on the desktop as well as various features such as glass window frames, 3-D window transition animations, Windows Flip and Windows Flip3D, and high resolution support.

Functions

DwmFlush() → int dwmapi
Issues a flush call that blocks the caller until the next present, when all of the Microsoft DirectX surface updates that are currently outstanding have been made. This compensates for very complex scenes or calling processes with very low priority.
DwmFlush() → int dwmapi

DwmGetTransportAttributes(Pointer<Int32> pfIsRemoting, Pointer<Int32> pfIsConnected, Pointer<Uint32> pDwGeneration) → int dwmapi
Retrieves transport attributes.
DwmGetTransportAttributes(Pointer<Int32> pfIsRemoting, Pointer<Int32> pfIsConnected, Pointer<Uint32> pDwGeneration) → int dwmapi
Retrieves transport attributes.
DwmGetWindowAttribute(int hwnd, int dwAttribute, Pointer<NativeType> pvAttribute, int cbAttribute) → int dwmapi
Retrieves the current value of a specified Desktop Window Manager (DWM) attribute applied to a window.
DwmGetWindowAttribute(int hwnd, int dwAttribute, Pointer<NativeType> pvAttribute, int cbAttribute) → int dwmapi
Retrieves the current value of a specified Desktop Window Manager (DWM) attribute applied to a window.
DwmGetWindowAttribute(int hwnd, int dwAttribute, Pointer<NativeType> pvAttribute, int cbAttribute) → int dwmapi
