Application.WindowHandle32 Property

  • Article
Visio Automation Reference

Returns the 32-bit handle of a Microsoft Office Visio window. Read-only.

Version Information
 Version Added:  Visio 4.0

Syntax

expression.WindowHandle32

expression   A variable that represents an Application object.

Return Value
Long

Remarks

The WindowHandle32 property of an Application object returns one of the following:

  • The HWND for the main Visio (frame) window (most common).
  • The HWND for the container application's main frame window if Visio is running in-place and active.
  • The HWND for the window returned by the GetActiveWindow() function if either frame window is disabled (for example, if a modal dialog box is running). For details about the GetActiveWindow function, see the Microsoft Platform SDK on the Microsoft Developer Network (MSDN) Web site.

Use the WindowHandle32 property of the Window object to obtain the HWND for a window in the Windows collection of a Visio instance.

You can use the obtained HWND in Windows API calls.

Dim lngWindowHandle32 As Long 

'Get the active window.
Set vsoWindow = ActiveWindow 

'Get the 32-bit handle of the active window. 
lngWindowHandle32 = vsoWindow.WindowHandle32 

'Verify that you got the handle.
