  1.   

    TextOut(hdc,cxChar,rect.bottom-cyChar,szBuffer,  
                                         wsprintf(szBuffer,szFormat[iType],

    ''中间没有字符,看你的意思应该是要输出空格吧 ' '

  3.   

    补充楼上一下！
    最关键的地方！ hWnd=CreateWindow(szAppName,"填充示例程序",  // 窗口类当然要用你刚刚注册的窗口类
                                                 WS_OVERLAPPEDWINDOW,  
                                               CW_USEDEFAULT,0,  
                                                                   CW_USEDEFAULT,0,  
                                                                   NULL,NULL,  
                                                                   hInstance,NULL);  这里的第一个参数应该是你注册窗口时的名称即：szAppName，而不是WinFill。
