You also can use the Front Panel Window:State property to set the state of a front panel window that is already open.
|State||No||Sets the state in which to open the front panel window.|
Minimize a caller VI while a subVI is running.
If you would like to minimize the caller VI, for example if you have a main VI that does essentially nothing while the subVI that it calls is executing, you need to reference your calling VI. So upon calling your subVI the first action would be to open a reference to your calling VI and size its front panel appropriately by using the VI Property Node. Then when exiting the subVI after completing execution you can restore the calling VI's front panel to its original size and close the reference.
Under Windows 98/2000 you can effect the above behavior with a couple of simple calls to the user32.dll API. First you get a handle to the window of the calling VI (or other Window) and then call either:
The info on making the calls can be found for free at Microsoft at:
or by going to http://msdn.microsoft.com and search on ShowWindow or AnimateWindow.
