Interop Forms Toolkit
How To Handle an InteropForm Event

Handling Events

Handling events from InteropForms is just like handling events exposed by any other Visual Basic 6.0 objects.  Simply declare a member variable using the WithEvents keyword.

' Declare the .NET HelloWorldForm
Dim WithEvents hello As HelloWorldForm

Then, using the drop-down list add the event handler:
 

Then add your code:

' Handle the SampleEvent event.
Private Sub hello_SampleEvent(ByVal sampleEventText As String)
    MsgBox sampleEventText
End Sub
