ActiveX controll in .NET

Question

I have an activeX control (compiled ot source) that I need to use in .NET Compact Framework. I can't add it using the normal methods, it says it is not a valid COM server. so i converted it to a .net assembly using tlbimp and it allowed me to bring it into the IDE, but it gives me a 'managed unhandled exception error when i try to instance it. I was told that .net compact framework wouldn't support an activeX control and that I would have to write a wrapper. Any information on where to start with this wrapper would be much appreciated. Thanks, Duddits
