GetFocus
The GetFocus
function retrieves the handle of the window that has the keyboard focus, if the
window is associated with the calling thread s message queue.
HWND GetFocus(VOID)
Parameters
This function
has no parameters.
Return Values
If the
function succeeds, the return value is the handle of the window with the
keyboard focus. If the calling thread s message queue does not have an
associated window with the keyboard focus, the return value is NULL.
Remarks
Even if GetFocus
returns NULL, another thread s queue may be associated with a window that has
the keyboard focus.
Use the GetForegroundWindow
function to retrieve the handle to the window with which the user is currently
working. You can associate your thread s message queue with the windows owned
by another thread by using the AttachThreadInput function.
