you can create a main function. Create an instance of your class in the main function. And then call the function with the object/pointer variable. Suspicious | :suss:

The same as you did in C++
In MFC applications however the main function is hidden.

Somethings seem HARD to do, until we know how to do them.

include the header file, where u want to create the object and functions. Then create objct and call function

In VC u can creatte diff. kind of projects using the wizards, so dont compare it with c++ main().

If u want to create dos type app, use Win32 Console App. wizrd.
u can create Windows app, using Win32 App wizrd..In this case u can see WinMain instead of main()

First learn about how to use VC++ and then start programming than this kind of Quick start....Slow and Study WIN(dows)the race Smile | :)

there are many thing and function are become obslete or replaced by better function in VC++ for Example Void main () is replaced by WinMan() in Win32 and CWinApp Wrap same in MFC!
so moral of story bought a VC++ book or look for online material to learn vc++...
have a look at Visual C++ 6 Unleashed (link Provided to me by VuniC)

Try this :

CString consoleData=ExecuteExternalFile("cmd.exe","Notepad");
//AfxMessageBox(consoleData);
// consoleData has the MS-DOS text

I hope this will help

ok..Another way..Take project->Setting->C++ tab

in the category combo take "Precompiled Headers"

Now check the Radio button "Not using precompiled headers".

Then rebuild the preoject.
