怎么创建一个窗口

如果选 win32 Application，那么就要编写窗口类，注册窗口类，写窗口消息处理函数，创建窗口，显示窗口，大致就这几个步骤。

如果选MFC Appwizard的话，就要从Cwnd类，或者其他窗口类继承，然后显示就可以了。你可以看看windows程序设计这方面的资料。

主要是第一个窗体类其他的2个类是我封装的WINDOWS API

生产窗体可以使用CreateWindowEx函数。

函数功能：该函数创建一个具有扩展风格的层叠式窗口、d出式窗口或子窗口，其他与CreateWindow函数相同。

函数原型：

CreateWindowEx函数创建一个层叠的，自动d出的（pop－up）或是一个子窗口通过扩展格式。另外这个函数的作用与CreateWindow函数的作用相同。要获得更多的关于创建窗口的信息和关于CreateWindowEx函数参数的详细描述。参见CreateWindow

HWND CreateWindowEx(

DWOR DdwExStyle,        //窗口的扩展风格

LPCTSTR lpClassName,    //指向注册类名的指针

LPCTSTR lpWindowName,   //指向窗口名称的指针

DWORD dwStyle,          //窗口风格

int x,                  //窗口的水平位置

int y,                  //窗口的垂直位置

int nWidth,             //窗口的宽度

int nHeight,            //窗口的高度

HWND hWndParent,        //父窗口的句柄

HMENU hMenu,            //菜单的句柄或是子窗口的标识符
