MFC下的键盘响应代码

MFC下的键盘响应代码

在PreTranslateMessage(MSG* pMsg)函数中添加：

1、响应回车键：

if(pMsg->message==WM_KEYDOWN && pMsg->wParam==VK_RETURN)
    MessageBox("你按下了键盘上的回车键！");

2、响应上、下、左、右键：

CWnd* pWndNext;
if (pMsg->message==WM_KEYDOWN){
        switch (pMsg->wParam){
           case VK_LEFT:
           	AfxMessageBox("左键");
           	break;
           case VK_RIGHT:
           	AfxMessageBox("右键");
           	break;
           case VK_UP:
           	AfxMessageBox("上");
           	break;
           case VK_DOWN:
		AfxMessageBox("下");
		pWndNext = GetNextDlgTabItem(GetFocus());//跳转到下一控件
		if (pWndNext) 
		{
			pWndNext->SetFocus();
		}
           	break;
           case VK_SPACE:
           	AfxMessageBox("空格");
           	break;
