Solution 1

Kernel calls WinMainCRTStartup function, and WinMainCRTStartup calls WinMain, and WinMain calls AfxWinMain.

WinMain is defined in a file called appmodul.cpp which is part of the MFC source.

The CRT startup will call this WinMain as posted by Jast_in.
This WinMain then calls a global MFC function called AfxWinMain which then goes on to call your CWinApp derived class' InitInstance method.

If you have a dialog based application, you call DoModal in InitInstance and then return FALSE so that no further processing happens.

If you have a SDI or MDI application, the control enters a Run function called from AfxWinMain after calling InitInstance.

This Run method contains the message loop needed to dispatch Windows messages to the window procedure.
