How do you link a programming with other programming languages?

Answer 1

This is done via a call sequence. The syntax is different between languages but the process is about the same. The calling program issues a call to the called program and passes data items known as arguments. These arguments are used to instruct the called program on what actually to do. After the called program has completed its function it passes these arguments back to the calling program along with a return code to inform the calling program everything was ok, or not ok.

Answer 2

You cannot link two separate programs. What you can do is compile one program as a link library and then link the other program to that library, either statically or dynamically. An integrated development environment that supports both languages is the simplest solution. For instance, in Visual Studio you can write a Visual C++ program that links to a Visual Basic DLL or vice versa.
