Application.hWndAccessApp (Access)
You can use the hWndAccessApp method to determine the handle assigned by Windows to the main Microsoft Access window.
The hWndAccessApp method returns a Long Integer value set by Access and is read-only. You can use this method by using Visual Basic when making calls to Windows application programming interface (API) functions or other external procedures that require a window handle as an argument. To get the handle to a window containing an Access object such as a Form or Report, use the hWnd property.
Dim lnghWndAccessApp As Long
lnghWndAccessApp = hWndAccessApp
