Windows 函数

//使用CreateWindow之前要先依次 【定义】和 【注册】 【窗口类型】
// 【定义】 并初始化
WNDCLASS wndclass;
......
wndclass.lpszClassName = TEXT("WindowClassName");
...... // 【注册】
if (!RegisterClass (&wndclass))
{
MessageBox ( NULL, TEXT ("This program requires Windows NT!"), szAppName, MB_ICONERROR) ;
return ;
} //CreateWindow 与 窗口类型wndclass 的联系是通过 CreateWindow 第一个 参数建立起来的
// 如果要使用上面第3行定义的 wndclass 则使用时第一个参数如下： hwnd1 = CreateWindow( TEXT("WindowClassName"), // window class name
.
.
.
NULL) ; // creation parameters //CreateWindow 后必须使用以下两函数才能 显示和刷新
ShowWindow (hwnd1, iCmdShow) ; //设置特定的状态
UpdateWindow (hwnd1) ; // 向procedure 发送 MS_PAINT
