Can VB6 Call a C# COM object Overloaded Method

Question

I have a C# COM object with two public methods.

SendMessage()
SendMessage(int priority)

I am trying to call these methods from a VB6 project, but intellisense shows only the method without the priority. If I try entering a priority anyway I get a compile error, "Wrong number of arguments or invalid property assignment".

Am I just doing something wrong, or do I need to change the C# dll?

There's no overloading in VB6 so you can't have multiple functions with the same name. — xxbbcc

@MethodMan what more does this question need? It seems clear, to the point, and an issue the querent was having. — Jon Hanna

I also don't see why it was closed. The question is perfectly clearly formulated. There are no "debugging details" required. — tmighty

or do I need to change the C# dll

If you can, then that would be for the better, as COM does not support overloading, so it is best avoided with COM-visible interfaces.

There should be a method in the COM interface that is something like SendMessage_2(int priority) bound to your SendMessage(int priority) though.
