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 Required. An expression that returns one of the objects in the Applies To list.


This property is available only by using a macro or Visual Basic for Applications (VBA) code.

You can use this property in VBA code 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.

' 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
End If
End Sub
