These API function I tried with VB2005 and it worked fine. You can write vb application to open , close and move , resize another window application as word, excell. You also can use trasparent API to make color of window application fade away , until it disappear

'move

<DllImport("user32.dll", EntryPoint:="MoveWindow", CharSet:=CharSet.Auto)> _

Public Shared Function MoveWindow(ByVal hWnd As IntPtr, _

ByVal X As Int32, _

ByVal Y As Int32, _

ByVal nWidth As Int32, _

ByVal nHeight As Int32, _

ByVal bRepaint As Boolean _

) As Boolean

End Function

'transparence
