Hi,
I'm a C++ newbie and have a liitle problem I hope someone can help me with here.

I have a Visual C++ project consisting of about 20 source files, one of which contains main(). I originally built a dialog-based application, and have no menus in the application. I am trying to run main(), by clicking on a Control button, "Analyze", inside the OnAnalyze() function.

From my understanding, main() is supposed to harness all my other source files and implement it. Now, I need to run main() from a control button, in my MFC application. The project compiles with no errors at present but I don't know how to run main() with the control button.

Or would it may be necessary to implement an instance of the control in main()?

Thaanks a lot in advance!

I do not see why you would want to call main().

To explain.
Main is the common name for the entry point of a program. The entry point is the place where execution starts. It is used by the OS and the Runtime to start and run your program. Calling it your self is at best very risky and worst a disaster. Do Not Try. Further since your application is written with the MFC you should not even have a main in your source. It is implemented within the MFC and needs to be inorder for the MFC to do its thing.

Another thing to note is that the name main is not a must. It is defined in the build settings of your compiler and when using the MFC is acctually called something like WinMainCRTStartup.

You should move the functionaly of your main function to something with a less confusing name and call that from OnAnalyze()
