Return Value
If true, HotKey processing uses a global system hook. Otherwise, normal hot key processing is performed.For an example, refer to ScreenCaptureEngine.
Normally, when a capture function is called, the function enters a loop, and waits
for the HotKey specified in nHotKey to be pressed, at which point it performs the
capture. This loop can
cause the CPU usage indicator to appear maxed out.
Specifying the
OptimizedHotkey
property to be true
will cause the capture
method to return immediately (if a HotKey has been specified in Hotkey
).
In this case, a global system HotKey hook is established and used to wait for the
HotKey to be pressed. When the HotKey is pressed, the capture is performed and
the event handler is called with the results of the capture. Use this option only
if the normal behavior is causing your application problems. This option is
ignored in Win95/98/Me.
