可以的，我在程序中就用了（如下）：
BOOL CPFView::PreTranslateMessage(MSG* pMsg)
{
if (pMsg->message == WM_KEYDOWN)
{
CString key=_T("");
switch (pMsg->wParam)
{
case VK_PRIOR://PAGE UP
break;
case VK_NEXT://PAGE DOWN
break;
case VK_UP://向上
break;
case VK_DOWN://向下
break;
case VK_LEFT://向左
break;
case VK_RIGHT://向右
break;
default:
break;
}
}

return CFormView::PreTranslateMessage(pMsg);
}

是不是程序出错了？
建议自己检查一下代码

一样一样的

1、CFormView是CWnd的子类,可以响应WM_KEYDOWN消息！
2、你执行KeyDown的时候，叮叮叮……响个不停，在DeBug里根本看不到nChar, nRepCnt, nFlags的值。这是因为你的CFormView里放了其他控件的缘故，如果CFormView里没有任何控件（把Wizard生成的那个Static静态文本控件删除）的话，CFormView就可以响应WM_KEYDOWN消息了！
3、重载PreTranslateMessage虚函数可以解决你必须用FormView做基类，还必须要用KeyDown的问题：
用FormView做基类，我估计你想添加控件，而有了控件后，WM_KEYDOWN消息就不会响应了，所以得重载视类的PreTranslateMessage虚函数。如下：
用这个BOOL CMyView::PreTranslateMessage(MSG* pMsg)
{

if (pMsg->message == WM_KEYDOWN)
{
switch (pMsg->wParam)
{
case VK_DOWN: //下方向键
//你的操作代码
break;
case 65: //大写字母A的ASCII值
case 97: //小写字母a的ASCII值
//你的代码
break;
default:
break;
}

}
return CFormView::PreTranslateMessage(pMsg);
}
来代替你原来的
void CMyView::OnKeyDown(UINT nChar, UINT nRepCnt, UINT nFlags)
{
switch(nChar)
{
//你的代码
}
CFormView::OnKeyDown(nChar, nRepCnt, nFlags);
}
同时，你得把关于WM_KEYDOWN消息的映射关系去调。
多试试，有些问题就自己解决了！

你们好！
1、CFormView是CWnd的子类,应该可以响应WM_KEYDOWN消息，但是当我执行KeyDown的时候，叮叮叮……响个不停，在DeBug里根本看不到nChar, nRepCnt, nFlags的值。无论框架还是视图都不接受该消息！看来只有重载下面的虚函数了。
2、重载PreTranslateMessage虚函数，
BOOL CTelecomView::PreTranslateMessage(MSG* pMsg)
{
// TODO: Add your specialized code here and/or call the base class
if(pMsg->message == WM_KEYDOWN)
{
//这里消息如何Dispatch？
//如何能使ON_KEYDOWN消息有效？请指示…………
}
return CFormView::PreTranslateMessage(pMsg);
}

Formview单文档或对话框项目接受不到按键消息的解决办法
当对话框或formview界面上有控件时，由于焦点在控件上，因此wm_char,wm_keydown等按键消息会被控件捕获，而导致对话框或formview无法接受该类按键消息。这时候通常的解决方法是在对话框类或者forview类中重写PreTranslateMessage函数，该函数是在消息路由前的预处理函数，（经测试）该函数能够在控件处理按键消息之前对消息进行预处理。通常的解决思路是在该函数中将

对话框和常用控件

对话框是Windows应用程序中最重要的用户界面元素之一，是与用户交互的重要手段，在程 序运行过程中，对话框可用于扑捉用户的输入信息或数据。对话框是一个特殊类型的窗口，任何对窗口进行的操作（如：移动、最大化、最小化等）都可在对话框中 实施，一般来说，在对话框中通过各种控件（如：按钮、编辑框、列表框、组合框等）来和用户进行交互。控件是在系统内部定义的用于和用户交互的基本单元。

2001年01月14日 21:50:00 我们首先想到的是响应WM_KEYDOWN消息，但实际运行却发现没有任何效果。原因是对话框里的控件需要首先对按键作出响应，比如多行编辑框必须首先处理回车，不至于回车使对话框关闭。我们要想在第一时间对对话框的按键做出响应，需要重载PreTranslateMessage,以下的代码实现了在对话框中显示虚拟键值（virtual-key code）BOOL
