Private Declare Function GetWindowRect Lib "user32" (ByVal hwnd As Long, ByRef lpRect As RECT) As Long
Private Declare Function GetDesktopWindow Lib "user32" () As Long
Private Declare Function GetWindowDC Lib "user32" (ByVal hwnd As Long) As Long

Dim DskHwnd As Long     
Dim DskRect As RECT     
Dim DskHdc As Long      
Dim rc As Long 

DskHwnd = GetDesktopWindow() 
DskHdc = GetWindowDC(DskHwnd) 
rc = GetWindowRect(DskHwnd, DskRect)
Debug.Print DskRect.Left, DskRect.Top, DskRect.Right, DskRect.Bottom
