dotnet general: Hi All
i have an interface like this in file Interface.h
__gc __interface IParam
{

};

My implementation class is like this
public __gc class Param : IParam
{
}

The ablove implementation class is in a separate assembly.

In my application i'm using Activator::CreateInstance to create class from
Assembly dynamically
System.Runtime.Remoting.ObjectHandle * hdl ;
hdl = Activator::CreateInstance(AssemblyName, ClassName)

IParam = __try_cast<IParam*>(hdl->Unwrap());

here i'm getting invalid cast operation...
I have included IParam interface in my app as source file.
Can anybody help me what's going wrong..

Thanks and Regards
Krishna

I suspect that including the IParam interface in your app is the
problem. Have a look at http://www.pobox.com/~skeet/csharp/plugin.html
- it's looking at things from a C# perspective, but I suspect the same
principles apply.
