OnFileOpen kEventHandled not working

[Anonymous]

I did a search and found the previous thread on C# with the same issue.  This is in VB.net.  I have tried changing copy local to false on the inventor interop, and I have tried changing the project back to Net Framework 3.5 but neither has fixed the problem. 

When I step through the code it is firing the event and I am setting the handling code to handled, but I still always get the dialog. 

Anyone have any other ideas?

Hi,

When you set the event as handled, do you also handle "getting the filename. and also set the FileName argument".

Thank you, that appears to have been the problem. I am not really sure I understand why the filename needs to be provided when we are setting it to handled.  OnFileNewDialog doesn't require any other arguments.
