The two “overloads” aren't in the same scope. By default, the compiler only considers the smallest possible name scope until it finds a name match. Argument matching is done *afterwards*. In your case this means that the compiler sees `B::DoSomething`. It then tries to match the argument list, which fails.

Overload resolution is one of the ugliest parts of C++
Basically the compiler finds a name match "DoSomething(int)" in the scope of B, sees the parameters don't match, and stops with an error.
It can be overcome by using the A::DoSomething in class B

When you define a function in a derived class then it hides all the functions with that name in the base class. If the base class function is virtual and has a compatible signature then the derived class function also overrides the base class function. However, that doesn't affect the visibility.

If you wrote the applet and have source, then you could try to migrate the Java Applet to a J# Browser control and stuff that in your .net application.

The function is hidden by the function with the same name in the subclass (but with a different signature). You can unhide it by using the using statement, as in using A::DoSomething(); |
The problem may be cause by VB.NET & C# projects using different naming conventions for project assemblies and how the project namespace is used. At least that's were I would start looking. |
