以下是鼠标点击图片控件中一点得到该点在图片控件中的坐标的代码，如果有三个图片控件，怎样修改才能实现点击某点得到那点在所属图片控件中的坐标？不胜感激！

[xujiayuan1992]

BOOL CzuobiaoDlg::PreTranslateMessage(MSG* pMsg)
{
// TODO: Add your specialized code here and/or call the base class

    if(pMsg->message == WM_LBUTTONDOWN && GetDlgItem(IDC_ShowImg)->GetSafeHwnd() == pMsg->hwnd )

    OnLButtonDown(MK_LBUTTON, pMsg->pt);   //在此传递点击部位在对话框中的坐标

    return CDialog::PreTranslateMessage(pMsg);
}

void CzuobiaoDlg::OnLButtonDown(UINT nFlags, CPoint point)
{
	// TODO: 在此添加消息处理程序代码和/或调用默认值
	CRect rect_ctr;
    (this->GetDlgItem(IDC_ShowImg))->GetWindowRect(&rect_ctr);//获取Picture控件相对屏幕左上角的坐标，
    //存储到rect_ctr中

    ScreenToClient(rect_ctr);//获取Picture控件相对对话框客户区左上角的坐标
    point.x -=  rect_ctr.left;//point获取的是鼠标相对对话框客户区左上角的坐标，减去rect_ctr.left和
    point.y -=  rect_ctr.top;//rect_ctr.top后，即为鼠标相对Picture控件左上角的坐标
}

在pretrans中直接把控件的坐标转成dlg的坐标就可以了 用mapwindowpoints

GetCursorPos() CStatic::ScreenToClient();

void CDlgTmpDlg::OnLButtonDown(UINT nFlags, CPoint point)
{
	// TODO: 在此添加消息处理程序代码和/或调用默认值
	CPoint ptDest = point;
	CRect rect_ctr[3];	
	ClientToScreen(&ptDest);
	(GetDlgItem(IDC_PICTURE1))->GetWindowRect(&rect_ctr[0]);
	(GetDlgItem(IDC_PICTURE2))->GetWindowRect(&rect_ctr[1]);
	(GetDlgItem(IDC_PICTURE3))->GetWindowRect(&rect_ctr[2]);
	
	if(isInRect(ptDest,rect_ctr[0]))
	{
		(GetDlgItem(IDC_PICTURE1))->ScreenToClient(&ptDest);
	}
	else if(isInRect(ptDest,rect_ctr[1]))
	{
		(GetDlgItem(IDC_PICTURE2))->ScreenToClient(&ptDest);
	}
	else if(isInRect(ptDest,rect_ctr[2]))
	{
		(GetDlgItem(IDC_PICTURE3))->ScreenToClient(&ptDest);		
	}
	//CDialogEx::OnLButtonDown(nFlags, point);
}


BOOL CDlgTmpDlg::PreTranslateMessage(MSG* pMsg)
{
	// TODO: 在此添加专用代码和/或调用基类
	if(pMsg->message == WM_LBUTTONDOWN && (GetDlgItem(IDC_PICTURE1)->GetSafeHwnd() == pMsg->hwnd
		|| GetDlgItem(IDC_PICTURE2)->GetSafeHwnd() == pMsg->hwnd
		||GetDlgItem(IDC_PICTURE3)->GetSafeHwnd() == pMsg->hwnd))

		OnLButtonDown(MK_LBUTTON, pMsg->pt); 

	return CDialogEx::PreTranslateMessage(pMsg);
}

bool CDlgTmpDlg::isInRect( CPoint pt,CRect rect )
{
	bool bReturn = false;
	if(pt.x >= rect.left && pt.x <= rect.right &&pt.y >= rect.top && pt.y <= rect.bottom)
		bReturn = true;
	return bReturn;
}

不知道能不能满足要求，只适用与3个控件不重叠的情况
