tlbimp creating incorrect assembly Messages   Related Types This message was discovered on ASPFriends.com 'aspngmigrate' list. Carey Loomis -- This message, which was originally sent to "aspngconfig", has been moved to "aspngmigrate" mailing list by the List Master -- 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 Reply to this message...        Martin & Leah Lacey 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.
