System.Runtime.InteropServices.COMException (0x86DB0898)

[WPfeffer]

I have another mess that I haven't found an answer for and maybe one of you
wonderful people out there can help. It's actually quite simple what I'm
trying to do, I just want to add the 'MarkerEvent'
((short)VisEventCodes.visEvtApp + (short)VisEventCodes.visEvtMarker) to
AddAdvise. My code:

public void OnConnection(object application,
Extensibility.ext_ConnectMode connectMode, object addInInst, ref System.Array
custom)
{
vsoApplication =
(Microsoft.Office.Interop.Visio.Application)application;
addInInstance = addInInst;
EventList applicationEventList = vsoApplication.EventList;
try
{
markerEvent = applicationEventList.AddAdvise(MarkerEvent,
applicationEventSink, "", "");
}
catch (COMException e)
{
System.Windows.Forms.MessageBox.Show(e.ToString());
}

vsoApplication.Documents.OpenEx(@"C:\Documents and
Settings\wep85069\My Documents\VisionBots.vst",
(short)VisOpenSaveArgs.visOpenCopy);
}


The error:

System.Runtime.InteropServices.COMException (0x86DB0898)

The error is thrown at the:
markerEvent = applicationEventList.AddAdvise(MarkerEvent,
applicationEventSink, "", "");

line.

Any help or suggestions would be greatly appreciated. I have tried adding
the [COMVisible (true)] attribute above the 'public void OnConnection ....'
definition, but I still get the same error. I also have the 'Make assembly
COM-Visible' check box checked in the 'Assembly Information' dialog part of
the project settings.

Thank you.

Does you EventSink class have the COMVisible tag?
Eg
<ComVisible(True)> _
Public Class EventSink
Implements IVisEventProc

I came in this morning and thought that I would try your suggestion. Before I
did however, I rebuilt the project, reinstalled, and now everything works
again. I'm not sure what happened and why it works now and it didn't before,
but if it stops working again, I will try your suggestion.

Thanks for the help.

Check if EventSink class is defined as public..
