VB.Net calling a COM object error.

Recommended Posts

I''m using VB.Net to call a COM object that I created, and I''m geting the error:

An unhandled exception of type ''System.NullReferenceException'' occurred in BNetClient.exe

Additional information: Object reference not set to an instance of an object.



Dim result As Integer

Dim obj As BNet.CComm

obj = New BNet.CComm

result = obj.Bind("localhost", "9865")


It happens on my call to obj.Bind... Am I missing something? I have BNet loaded as a COM reference into the project, and the object viewer can correctly get the interface and all the methods, etc. I''ve stuck a breakpoint into the com object call but it never hits it, so I''m thinking its on the VB side or erroring out somewhere in the interopt/com libraries. I''m very new to VB.net (but a master of VB6) so please forgive me if this is a stupid question.
