VC(在主对话框上捕获按钮等控件上的鼠标消息)

比如。当鼠标移到按钮上时候，需要主对话框上显示出鼠标在哪一个按钮上

BOOL CTextbuttonDlg::PreTranslateMessage(MSG* pMsg) 
{

    CRect rectb;  
    GetDlgItem(IDC_BUTTON_B)->GetWindowRect(&rectb);  
if(rectb.PtInRect(pMsg->pt))  
    {  //SetDlgItemText(IDC_STATIC_TEXT,"");
        CString str;
        str="鼠标在按钮B上";
        SetDlgItemText(IDC_STATIC_TEXT,str);
    }
// TODO: Add your specialized code here and/or call the base class
    CRect rect;  
    GetDlgItem(IDC_BUTTON_A)->GetWindowRect(&rect);  
if(rect.PtInRect(pMsg->pt))  
    {  
        CString str;
        str="鼠标在按钮A上";
        SetDlgItemText(IDC_STATIC_TEXT,str);
    }

return CDialog::PreTranslateMessage(pMsg);
}这里需要在PreTranslateMessage(pMsg)提前捕获鼠标消息。否则的话按钮控件捕获的鼠标消息，对话框是不知道的
