I'm using tlbimp.exe to create an assembly dll from a 3rd party COM object.
The import works fine with two exceptions:

1) One of the methods takes an optional parameter. After conversion, .NET
shows it as a required parameter.
2) One of the methods returns an instance of another class in the library.
After conversion, .NET shows this method as returning a type of 'object'
rather than the proper class type. If I try to cast the returned object to
the desired class, I get an invalid cast exception.

Anyone know how to get around this?
Thanks,
Carey

thats the way it works (for now, anyway)

create variables for the no-longer optional arguments.

cast the returned object to the interface (_MyInteropClass) where
MyInteropClass in the name of the class you expected it to return.

Use the object browser and inspect the Interop classes generated.

Martin.
