窗口创建问题?

[root]

我在MainFrm中创建了一个标准的CWnd,代码如下:

WNDCLASS myclass;
myclass.style = CS_HREDRAW and CS_VREDRAW and CS_PARENTDC;
myclass.lpfnWndProc = AfxWndProc;
myclass.cbClsExtra = 0;
myclass.cbWndExtra = 0;
myclass.hInstance = AfxGetInstanceHandle();
myclass.hIcon = NULL;
myclass.hCursor = LoadCursor(NULL, IDC_ARROW);
myclass.hbrBackground = NULL;
myclass.lpszMenuName = NULL;
myclass.lpszClassName = "TaskItemWndClass";
AfxRegisterClass(&myclass);

return Create("TaskItemWndClass", _T("TASKItem"),WS_CHILD and WS_VISIBLE, rect, pParentWnd, 0);

窗口是显示出来了,但却不能接受任何消息,而且被其他MainFrm子窗口所覆盖后不能自己刷新.我实在没有想通,还有什么东西没有设置吗?请各位大虾赐教

补充一点:
该CWnd在CDialog下生成一切正常,但在MainFrm下......why?

不用SDK,直接Create("NULL,NULL,WS_CHILD and WS_VISIBLE,rect, pParentWnd, 0);也不行!!!

详细一点！！！！！！！

有没有：
ShowWindow (hWnd, SW_SHOWMAXIMIZED);
UpdateWindow (hWnd);

while ( GetMessage (&msg, NULL, 0, 0) ){
TranslateMessage (&msg);
DispatchMessage (&msg);
}

具体代码如下:

BOOL CMyWnd::DoCreate(const RECT &rect,CWnd* pParentWnd)
{
WNDCLASS myclass;
myclass.style = CS_HREDRAW and CS_VREDRAW and CS_PARENTDC;
myclass.lpfnWndProc = AfxWndProc;
myclass.cbClsExtra = 0;
myclass.cbWndExtra = 0;
myclass.hInstance = AfxGetInstanceHandle();
myclass.hIcon = NULL;
myclass.hCursor = LoadCursor(NULL, IDC_ARROW);
myclass.hbrBackground = NULL;
myclass.lpszMenuName = NULL;
myclass.lpszClassName = "TaskItemWndClass";
AfxRegisterClass(&myclass);

return Create("TaskItemWndClass", _T("TASKItem"),WS_CHILD and WS_VISIBLE, rect, pParentWnd, 0);
}

在MainFrm中有:
CMyWnd* m_pWnd; //.h文件

m_pWnd = new CMyWnd; //.cpp文件
m_pWnd->DoCreate(rect,this);
m_pWnd->SetActiveWindow();
m_pWnd->ShowWindow(SW_SHOWNORMAL);

1.wsoft说得对，如果用SDK必须加入消息处理代码：

ShowWindow (hWnd, SW_SHOWMAXIMIZED);
UpdateWindow (hWnd);

while ( GetMessage (&msg, NULL, 0, 0) ){
TranslateMessage (&msg);
DispatchMessage (&msg);
}

2.在myclass.lpfnWndProc = YourWndProc指明函数后，必须定义这个窗口函数处理消息：

LRESULT CALLBACK YourWndProc(HWND hWnd,UINT message,
WPARAM wParam,LPARAM lParam)
{
//处理消息
switch(message){
case WM_COMMAND:
......
default:
return (DefWindowProc(hWnd,message,wParam,lParam));
}
return (0);
}
