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.

expression .Hwnd

expression A variable that represents a Report object.

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.

Note Note

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.

' Enter on single line in Declarations section of Module window. 
Declare Function IsZoomed Lib "user32" (ByVal hWnd As Long) As Long 
 
Sub Form_Activate() 
 Dim intWindowHandle As Long 
 intWindowHandle = Screen.ActiveForm.hWnd 
 If Not IsZoomed(intWindowHandle) Then 
 DoCmd.Maximize 
 End If 
End Sub
