为什么我用PreTranslateMessage(MSG* pMsg) 函数移动控件…………

为什么我用PreTranslateMessage(MSG* pMsg) 函数按下键盘某个键就会移动两次呢？

if(pMsg->wParam==0x25)
{
GetDlgItem(IDC_BITMAP)->GetWindowRect(&rect);
ScreenToClient(&rect);
rect.OffsetRect(CSize(-33,0));
GetDlgItem(IDC_BITMAP)->MoveWindow(rect);
}
MFC.

使用下面的代码,测试过了,只移动一次

if (pMsg->message == WM_KEYDOWN)
{
if (pMsg->wParam == VK_LEFT)
{
CRect rect;
GetDlgItem(IDC_BITMAP)->GetWindowRect(&rect);
ScreenToClient(&rect);
rect.OffsetRect(CSize(-33,0));
GetDlgItem(IDC_BITMAP)->MoveWindow(rect);
}
}
