Rest

Actually, nevermind. I had earlier only tested with the tools using the plugins, however when trying to connect it and invoking the methods myself in C++ there's nothing wrong. Guess I'll have a word with the developer. Still odd that the C++ and C# versions would work and not the VB.NET though. Thanks for the time anyway.

The C# version works just splendid. As far as I can tell, the methods Name, Version and RequiredCoreVersion doesn't pass data well These are the interface footprints I've worked out: Sub Name(<Out(), MarshalAs(UnmanagedType.LPStr)> ByRef Name As String) Sub Version(<Out()> ByRef Version As Integer) Sub RequiredCoreVersion(<Out()> ByRef RequiredCoreVersion As Integer) All others seem to do well though, and I've defined the out-parameters just the same.

I am trying to convert a C# COM object, which I've ported from Pascal, to VB.NET but this time I'm not as successful. I get very odd errors, like not getting any data passed in out-parameters of some of the methods. So if anyone, whom unlike me knows VB.NET, would care to give it a shot some people would be very grateful. Interface Implementation Thanks
