interop::GetDisplayIdFromMonitor function (microsoft.ui.interop.h)

  • Article

Gets the DisplayId that corresponds to the specified HMONITOR, if the hmonitor argument is valid.

Note

The microsoft.ui.interop.h header has a dependency on microsoft.ui.h, which is not shipped as part of the Windows App SDK. You can run the MIDL compiler (midl.exe) on Microsoft.UI.idl in order to generate microsoft.ui.h. Or just use the functions in the winrt/Microsoft.ui.interop.h header instead.

C#. For C# desktop application developers, the interop functions in this header are wrapped by the methods of the Microsoft.UI.Win32Interop class.
