   Hi Don,   
      
   You can use EnumWindows where you provide a callback method in a module, eg:   
      
   Put this method in a module   
      
   Public Function EnumWindowsProc(ByVal hwnd As Long, ByVal lParam As Long) As   
   Boolean   
      EnumWindowsProc = True ' continues   
   End Function   
      
   Use this decleration:   
      
   Public Declare Function EnumWindows Lib "user32" (ByVal lpEnumFunc As Long,   
   ByVal lParam As Long) As Long   
      
      
   and then invoke it such as :   
      
   Call EnumWindows(AddressOf EnumWindowsProc, someHwnd)   
      
      
   Alternatively you can use FindWindowEx, passing in the last found window as   
   the second parameter each time.
