How to know the ID of the control who received an event

Hi...

I have placed some ActiveX controls in a Dialog Resource. Those controls have to make some actions when the mouse is over or has clicked on it. I'm planning to use only 1 event handler to accomplish the actions for all controls so I need to know the ID of the control who has thrown the event.

How can I do it?
Thanks in advance

Hi,

Map the PreTranslateMessage(...) message handler to that dialog. And modify the code as

BOOL CMyDlg::PreTranslateMessage(MSG* pMsg)
{
      if(pMsg->message == WM_MOUSEMOVE)
      {
            CRect rect;
            GetDlgItem(IDC_EDIT1)->GetWindowRect(rect);
            if(rect.PtInRect(pMsg->pt))
            {
                  AfxMessageBox("Mouse On The Edit Box");
                  return CDialog::PreTranslateMessage(pMsg);
            }
            
            GetDlgItem(IDC_LIST1)->GetWindowRect(rect);
            if(rect.PtInRect(pMsg->pt))
            {
                  AfxMessageBox("Mouse On The List Box");
                  return CDialog::PreTranslateMessage(pMsg);
            }

            GetDlgItem(IDC_MY_DBGRID)->GetWindowRect(rect);
            if(rect.PtInRect(pMsg->pt))
            {
                  AfxMessageBox("Mouse On The DB Grid Box");
                  return CDialog::PreTranslateMessage(pMsg);
            }

            GetDlgItem(IDOK)->GetWindowRect(rect);
            if(rect.PtInRect(pMsg->pt))
            {
                  AfxMessageBox("Mouse On The OK Button");
                  return CDialog::PreTranslateMessage(pMsg);
            }

      }
      return CDialog::PreTranslateMessage(pMsg);
}

here I have taken some normal controls and a activex dbgrid control. U can make out by thier ID. But here U R not getting the ID's but, u will know where the mouse is. So u can replace the AfxMessageBox() with Ur function call and their U know the id also as if it says I am in DBGrid, then ID is known as ID_MY_DBGRID.

Hope this helps.
