XTP_NM_REPORT_SORTORDERCHANGED crash

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Using 12.0.1. Same code for 13.2...

From source comments:

This is what the DOCUMENTATION SAYS:
// BEGIN_MESSAGE_MAP(CReportSampleView, CXTPReportView)
//     ON_NOTIFY(XTP_NM_REPORT_SORTORDERCHANGED, XTP_ID_REPORT_CONTROL, OnReportSortOrderChanged)
// END_MESSAGE_MAP()
//
// void CReportSampleView::OnReportSortOrderChanged(NMHDR*  pNotifyStruct, LRESULT* /*result*/)
// {
//     XTP_NM_REPORTRECORDITEM* pItemNotify = (XTP_NM_REPORTRECORDITEM*) pNotifyStruct;
//     ASSERT(pItemNotify != NULL);
//
//     // TODO: Handle command.
// }

From source:
This is what the CODE DOES:
m_pControl->SendNotifyMessage(XTP_NM_REPORT_PRESORTORDERCHANGED); // Second parameter is NULL!

LRESULT CXTPReportControl::SendNotifyMessage(UINT nMessage, NMHDR* pNMHDR) const <------ NULL!
{
 if (!IsWindow(m_hWnd))
  return 0;
 NMHDR nmhdr;
 if (pNMHDR == NULL)
  pNMHDR = &nmhdr; <---------- assignment!
 pNMHDR->hwndFrom = GetSafeHwnd();
 pNMHDR->idFrom = GetDlgCtrlID();
 pNMHDR->code = nMessage;
 CWnd *pOwner = GetOwner();
 if (pOwner && IsWindow(pOwner->m_hWnd))
  return pOwner->SendMessage(WM_NOTIFY, pNMHDR->idFrom, (LPARAM)pNMHDR); <--- NOT the struct we expect!
 else
  return 0;
}

WM_NOTIFY does NOT send a XTP_NM_REPORTRECORDITEM struct for XTP_NM_REPORT_PRESORTORDERCHANGED message! So you will get a CRASH!

It's a bug. Period. End of discussion. Please fix it.

	piece of XTPRecordHeader.cpp file ver 12.1: m_pControl->SendNotifyMessage(XTP_NM_REPORT_PRESORTORDERCHANGED); if (bGroupOrderChanged) m_pControl->Populate(); else m_pControl->ReSortRows(); m_pControl->SendNotifyMessage(XTP_NM_REPORT_SORTORDERCHANGED);

	FACT: My post shows a bug OR erroneous documentation. You obviously did not read it.

	No, I do. You can use derived classes with extra details used
