The following sample code shows how to set the object data for the object with an ID of WP_SAMPLE, to have the specified title and use the specified help panel:

HOBJECT hObj;
BOOL    rc;

{
  hobj = WinQueryObject( "<WP_SAMPLE>" );
  if (hObj != NULLHANDLE)
  {
    /* WinQueryObject of WP_SAMPLE was successful */
    rc = WinSetObjectData(hObj,
                          "TITLE="Sample Object;
                          HELPPANEL=SAMPLEHELP_ID");
    if (rc)
    {
      /* Object data is set */
    }
    else
    {
      /* WinSetObjectData failed */
    }
  }
}
