Question

VB 6 can host web pages, which means it can also host Silverlight apps.

Communication from VB 6 to Silverlight can easily be done via URLs. But is there a way for the Silverlight app to send messages back to VB 6?

Answer 1

Ok how about this then.. Within the SilverLight app use the HtmlPage class to update the title of the page this can be monitored from the WebBrowser_TitleChange event in vb.

Silverlight code :-

var document = HtmlPage.Document;
document.SetProperty("title","whatever you need");

VB6 code :-

Private Sub WebBrowser_TitleChange(ByVal Text As String)        
    Debug.Print "Title changed to : " & Text        
End Sub

You’d have to ignore the initial TitleChange event when the page loads.
