Hide a program from the Windows task barTag(s): WinAPI/Registry
You can set the visible property of a window to false
but the window is not visible anymore.
w_window.visble = false
To keep the window visible but not in the task bar, define the external function
and then in the window open event
FUNCTION ulong SetWindowLongA( ulong hWnd, int nIndex, long newValue ) & LIBRARY "USER32.DLL"
long ll_rc ll_rc = SetWindowLongA(Handle(This), -20, 128) IF ll_rc = 0 THEN // something wrong on the kingdom! END IF
