Make one of them a DLL, or compile and link them together in a single project, or make one of them a COM server. Lots of possibilities.

You really have to be way more explicit because your question is so vague that it could mean a lot of different things. What are you trying to do exacty ? Calling a function from another program ? Using part of the code of the other program in your own code ? Displaying the other program in a window of your program ? ...

So please describe your problem precisely and if possible with a clear example.

If you wish to use functions and classes from another program you can just include their files in the project, if you wish to run another program from yours you can use CreateProcess

But you need to describe what you want to do better because it is not very clear. :)
