Report.Hwnd Property (Access)
You can use the hWnd property to determine the handle (a unique Long Integer value) assigned by Microsoft Windows to the current window. Read/write Long.
You can use this property in Visual Basic when making calls to Windows application programming interface (API) functions or other external routines that require the hWnd property as an argument. Many Windows functions require the hWnd property value of the current window as one of the arguments.
Because the value of this property can change while a program is running, don't store the hWnd property value in a public variable.
The following example uses the hWnd property with the Windows API IsZoomed function to determine if a window is maximized.
