Example

This class module shows how to define a sink class called KeyboardListener that listens for events fired by keyboard actions in the active window. It declares the object variable vsoWindow by using the WithEvents keyword. The class module also contains event handlers for the KeyDown, KeyPress, and KeyUp events.

To run this example, insert a new class module in your Microsoft Visual Basic for Applications (VBA) project, name it KeyboardListener, and insert the following code in the module.

Dim WithEvents vsoWindow As Visio.Window

Private Sub Class_Initialize()

    Set vsoWindow = ActiveWindow
    
End Sub

Private Sub Class_Terminate()

    Set vsoWindow = Nothing

End Sub


Private Sub vsoWindow_KeyDown(ByVal KeyCode As Long, ByVal KeyButtonState As Long, CancelDefault As Boolean)
    
   Debug.Print "KeyCode is "; KeyCode
   Debug.Print "KeyButtonState is" ; KeyButtonState
        
End Sub

Private Sub vsoWindow_KeyPress(ByVal KeyAscii As Long, CancelDefault As Boolean)
    
   Debug.Print "KeyAscii value is "; KeyAscii
                
End Sub

Private Sub vsoWindow_KeyUp(ByVal KeyCode As Long, ByVal KeyButtonState As Long, CancelDefault As Boolean)
    
   Debug.Print "KeyCode is "; KeyCode
   Debug.Print "KeyButtonState is" ; KeyButtonState
        
End Sub

                

Then, insert the following code in the ThisDocument project.

Dim myKeyboardListener As KeyboardListener

Private Sub Document_DocumentSaved(ByVal doc As IVDocument)

    Set myKeyboardListener = New KeyboardListener

End Sub

Private Sub Document_BeforeDocumentClose(ByVal doc As IVDocument)

    Set myKeyboardListener = Nothing
    
End Sub

Save the document to initialize the class, and then press any key to fire a KeyPress event. In the Immediate window, the handler prints the ASCII code of the key that was pressed to fire the event.
