Following are details for CDM_GETFILEPATH :
http://msdn2.microsoft.com/en-us/library/ms646847.aspx

The CDM_GETFILEPATH message retrieves the path and file name of the selected file in an Explorer-style Open or Save As dialog box. The dialog box must have been created with the OFN_EXPLORER flag; otherwise, the message fails.

You can  use the CDM_GETFILEPATH message to get the full path of the selected file like following :

// Called when the selected file has changed
BOOL CMyFileDialog::OnNotify(WPARAM wParam, LPARAM lParam, LRESULT* pResult)
{
      OFNOTIFY* pOFN = (OFNOTIFY*)lParam;

      if (pOFN->hdr.code == CDN_SELCHANGE)
               {
            // Selection changed
            // Get the filename
            TCHAR szFileName[MAX_PATH];
            ::ZeroMemory(szFileName, MAX_PATH);
            GetParent()->SendMessage(CDM_GETFILEPATH, MAX_PATH, (LPARAM)szFileName);
            ProcessFile(szFileName);
      }

      // Pass to base class
      return CFileDialog ::OnNotify(wParam, lParam, pResult);
}
