I think you can write this:
Code:
hwnd=dzHw1.GetActiveHandle
dzHw1.ShowWindow(hwnd,0)
On Device you can use Hardware library, If the .ShowTodayScreen() doesn't work you can use the KeyPress Library...
Try:
Code:
hw.KeyPress("s") <font color="Lime">'Normaly this emulate an Call Ended/Minimize all...</font>
If your Form is in fullscreen I noticed that it's hard to minimize it...
I hope it's usefull
Edit: An other soluce:
You can also use the Door library:
Code:
door.New1
door.FromControl("TestForm")
door.SetPropriete("WindowState",0)
But i think this work only on desktop but not sure...
