用vc 作的单文档程序，不需要F1系统帮助，如何屏蔽掉？

[yanw0212]

那位高手可以指教？

[Ah]

都说完了,混分

屏蔽掉一个系统键方法：
1：在自己的程序中处理如：F1，之类。
2：做一个键盘钩子。如：CTRL+ALT+DEL.

注：有的系统键可以通过函数屏蔽如WIN98下的CTRL+ALT+DEL。
先考虑方法1，不行就方法2.

[VCNULL]

最简单的办法就是从菜单中删除该菜单项，然后在快捷键（在资源中的Accelerator中）。

[vcforever]

重载CMainFrame类的PreTranslate()函数在函数中进行如下处理
BOOL CMainFrame::PreTranslateMessage(MSG* pMsg)
{
if(pMsg->message==WM_KEYDOWN){
if(pMsg->wparam == VK_F1)
return false;
}
return CMainFrame::PreTranslateMessage(pMsg);
}
就可以了！

祝你成功！

重载App的WinHelp

添加响应WM_HELPINFO的函数，然后删除里面代码，直接返回

在主程序的 WindowProc 中拦截 WM_HELP 并返回 TRUE 以过滤该消息

----
WM_HELP
Indicates that the user pressed the F1 key. If a menu is active when F1 is pressed, WM_HELP is sent to the window associated with the menu; otherwise, WM_HELP is sent to the window that has the keyboard focus. If no window has the keyboard focus, WM_HELP is sent to the currently active window.

Syntax

WM_HELP
lphi = (LPHELPINFO) lParam;

Parameters

lphi
Address of a HELPINFO structure that contains information about the menu item, control, dialog box, or window for which Help is requested.
Return Values

Returns TRUE.

Remarks

The DefWindowProc function passes WM_HELP to the parent window of a child window or to the owner of a top-level window.

直接删掉消息就可以了

[zhansg]

删除ACCELERATOR中键值为VK_F1的ID
或者删除消息映射即可

GZ

[rofole]

注释掉ON_COMMAND(ID_HELP, CWinApp::OnHelp)
