程序首先进入文件AppModul.cpp，找到_tWinMain()函数运行，调用其中的AfxWinMain()函数。
由于为了支持UNICODE,C运行库对WinMain其实区分了UNICODE版和ANSI版.对UNICODE版的程序,C运行库将调用wWinMain,而对于ANSI版的应用,则调用WinMain.
MFC的代码设计时是自动支持UNICODE的,所以,MFC的WinMain在APPMODUL.CPP被定义为_tWinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPTSTR lpCmdLine, int nCmdShow)，无论用户#define _UNICODE与否,MFC的WinMain都会被调用.

hInstance:表示该程序当前运行的实例句柄，它是一个数值。当程序在Windows下运行时，它唯一标识运行中的实例。
hPrevInstance:父窗口句柄。这个参数在Win32下已经不起作用了。
lpCmpLine:指定传递给应用程序的命令行参数。
nCmdShow:指定程序窗口如何显示，例如最大化、最小化、隐藏等。

这是个虚函数，pThread指向的是theApp，调用的是子类C***App类中的InitInstance函数。
KuaiPaiClient项目中的该函数为：
