一个关于系统菜单的小问题。

[冰壶2013]

我用ShowWindow使窗口最大化显示后，
想使“还原”按钮和“恢复”菜单失效，
我该怎么做？？？

还有，我想拜vc高手为师，以mail来“提问、回答”。
哪位肯收我这个徒弟，请EMAIL至：[e-mail]

用SetWindowLong，把窗口属性设为：WS_OVERLAPPED|WS_CAPTION|WS_SYSMENU|WS_THICKFRAME，也就是不加上WS_MAXIMIZEBOX和WS_MINIMIZEBOX就行了。

我按你说的做了，但有不少毛病!
1、WINDOWS的任务栏被挡住了。
2、系统菜单中“移动”菜单项被激活了。
2、在窗口的标题栏里双击，窗口变小，不是全屏幕了。
这些问题怎么解决？

按上面的方法去掉两个属性值后再ShowWidnow不就行了吗!

用ShowWindow就可以搞定,
注意参数!

用ShowWindow就可以搞定

[dingsg]

ShowWindow
The ShowWindow function sets the specified window's show state.

BOOL ShowWindow(
HWND hWnd, // handle to window
int nCmdShow // show state
);
Parameters
hWnd
[in] Handle to the window.
nCmdShow
[in] Specifies how the window is to be shown. This parameter is ignored the first time an application calls ShowWindow, if the program that launched the application provides a STARTUPINFO structure. Otherwise, the first time ShowWindow is called, the value should be the value obtained by the WinMain function in its nCmdShow parameter. In subsequent calls, this parameter can be one of the following values. Value Meaning
SW_FORCEMINIMIZE Windows 2000: Minimizes a window, even if the thread that owns the window is hung. This flag should only be used when minimizing windows from a different thread.
SW_HIDE Hides the window and activates another window.
SW_MAXIMIZE Maximizes the specified window.
SW_MINIMIZE Minimizes the specified window and activates the next top-level window in the Z order.
SW_RESTORE Activates and displays the window. If the window is minimized or maximized, the system restores it to its original size and position. An application should specify this flag when restoring a minimized window.
SW_SHOW Activates the window and displays it in its current size and position.
SW_SHOWDEFAULT Sets the show state based on the SW_ value specified in the STARTUPINFO structure passed to the CreateProcess function by the program that started the application.
SW_SHOWMAXIMIZED Activates the window and displays it as a maximized window.
SW_SHOWMINIMIZED Activates the window and displays it as a minimized window.
SW_SHOWMINNOACTIVE Displays the window as a minimized window.
This value is similar to SW_SHOWMINIMIZED, except the window is not activated.

SW_SHOWNA Displays the window in its current size and position.
This value is similar to SW_SHOW, except the window is not activated.

SW_SHOWNOACTIVATE Displays a window in its most recent size and position.
This value is similar to SW_SHOWNORMAL, except the window is not actived.

SW_SHOWNORMAL Activates and displays a window. If the window is minimized or maximized, the system restores it to its original size and position. An application should specify this flag when displaying the window for the first time.


Return Values
If the window was previously visible, the return value is nonzero.

If the window was previously hidden, the return value is zero.

Remarks
The first time an application calls ShowWindow, it should use the WinMain function's nCmdShow parameter as its nCmdShow parameter. Subsequent calls to ShowWindow must use one of the values in the given list, instead of the one specified by the WinMain function's nCmdShow parameter.

As noted in the discussion of the nCmdShow parameter, the nCmdShow value is ignored in the first call to ShowWindow if the program that launched the application specifies startup information in the STARTUPINFO structure. In this case, ShowWindow uses the information specified in the STARTUPINFO structure to show the window. On subsequent calls, the application must call ShowWindow with nCmdShow set to SW_SHOWDEFAULT to use the startup information provided by the program that launched the application. This behavior is designed for the following situations:

Applications create their main window by calling CreateWindow with the WS_VISIBLE flag set.
Applications create their main window by calling CreateWindow with the WS_VISIBLE flag cleared, and later call ShowWindow with the SW_SHOW flag set to make it visible.
Requirements
Windows NT/2000: Requires Windows NT 3.1 or later.
Windows 95/98: Requires Windows 95 or later.
Header: Declared in Winuser.h; include Windows.h.
Library: Use User32.lib.

我不知道怎么解决那三个问题!
SetWindowLong函数怎么用？

[Hidy]

CWnd* pWnd=AfxGetMainWnd();
CMenu* pMenu=pWnd->GetSystemMenu(FALSE);
pMenu->DeleteMenu(SC_RESTORE, MF_BYCOMMAND);

用该方法可以去掉[恢复]菜单，同时[还原]按钮也就失效了。
我也是新手，我的专家分还是个鸡蛋，所以我要拼命......

[冰壶2013]

Hidy:好!我会给你加分。你的专家分不会再是鸭蛋了。

但我那第三点怎么解决？也就是在标题栏里双击，窗口会变小。怎样使它失效。

[Hidy]

首先：处理消息映射函数WM_NCHITTEST（如果类向导没有，可在类向导选择Ｃlass Info，
把其改为Windows），代码如下：
UINT CMainFrame::OnNcHitTest(CPoint point)
{
UINT ret=CFrameWnd::OnNcHitTest(point);
if(ret==HTCAPTION && flag) ret=0;
return ret;
}
其中flag是一个布尔变量，初始值为ＦＡＬＳＥ，当你最大化窗口时把它设为ＴＲＵＥ。
昨天我刚送出第一分，今天就迎来第一专家分，谢谢！
希望大家一起支持ＣＳＤＮ，一方有？八方解答

还有一个更简单实用的方法:

ModifyStyle(WS_MAXIMIZEBOX|WS_MAXIMIZE , NULL);

这样一来[恢复]和[最大化]菜单全变灰,不用处理WM_NCHITTEST，
双击TITLE也不会变小，其中第一参数中有BOX的作用是禁止最大化
按钮，没BOX的作用是防止双击TITLE窗口变小。
这回你应该100%满意了吧，我可费了不少精力的。
