而且我运行之后整个都窗口都死掉了，关都关不了只有打开任务管理器才关掉

WM_CREATE差break;

关于自己是否适合编程的很简单的测试： 在报纸或杂志上随便找一段约1000字的文章，在Word中输入一遍。输完后再参考下面答案： A里面有10处以上文字或标点错误 B里面没有文字或标点错误并敢为此跟人打赌 C里面没有文字或标点错误并且字体和排版完全与原稿一致 D打印在半透明的纸上和原稿重叠在一起检查一模一样，且自我感觉很有成就感 A不适合编程（理由：打字准确度偏低、粗心大意） B初级程序员（理由：打字准确度很高、认真细致、自信、理解全角半角概念） C高级程序员（理由：在B的基础上理解字体和排版也是电脑打印的重要因素、但相比D还不够偏执、精益求精、结果可验证） D软件项目经理（理由：能针对项目给出令人信服的细致到极点的需求说明和典型测试用例。用户几乎挑不出毛病。专业！） 如果想从A变成B的话，到我的资源http://download.csdn.net/detail/zhao4zhong1/4084259里面下载“适合程序员的键盘练习”

没用啊？？不是这里问题？？

我想显示系统菜单 在windows程序设计.第10章里有个例子，可我运行就没有系统菜单还有就是什么都动不了只能靠任务管理器关闭？？？

上面这个我想显示一个按钮可显示不出来？？？ 两个问题是一个错误吗？？

[www_adintr_com]

case WM_SYSCOMMAND:
//
switch(LOWORD(wParam))
{
case IDR_SYS_MENU2:
    MessageBox(NULL,_T("aaa"),_T("aa)"),MB_ICONERROR);
   return 0;
}
return 0;

这里的 return 0 改成 DefWindowProc

case WM_SYSCOMMAND:
//
switch(LOWORD(wParam))
{
case IDR_SYS_MENU2:
    MessageBox(NULL,_T("aaa"),_T("aa)"),MB_ICONERROR);
   return 0;
}
return DefWindowProc(hwnd, message, wParam, lParam);

你不让系统处理移动，关闭这些消息，自然没有反应了。

HWND	hwndpop=CreateWindow(_T("aa"),_T("KK"),
WS_CHILD|WS_VISIBLE|BS_PUSHBUTTON,
10,20,30,40,hwnd,(HMENU)1,((LPCREATESTRUCT)lParam)->hInstance,NULL);

改成

			HWND	hwndpop=CreateWindow(_T("button"),_T("KK"),
				WS_CHILD|WS_VISIBLE|BS_PUSHBUTTON,
				10,20,30,40,hwnd,(HMENU)1,((LPCREATESTRUCT)lParam)->hInstance,NULL);

啥子咋办 系统菜单不是显示有的吗 你知道系统菜单是哪个不？ 在标题栏点右键弹出的菜单，你去试试，你添加的菜单项已经在里面了的。

大佬，太感谢啦
