Launch the ReportAddRecordEx sample, click on "Add records" button. Wait for all the items to be added.

Select the first row which display text "Column 1: Row - 1, Col - 1"). This row is now displayed in the header rows section.

Click any cell of this header row, then click on another one.

This produce a NULL pointer access in the method CReportControl::OnFocusChanging, its first parameter pNewRow being NULL.

This bug is still in the version 13.1.

At least, you should reply to people trying to help you finding bugs. Are you only interested in the money I spent buying your products ?

This is not 13.1 Core error - this is Sample error - not checked pointer. Coming from old time. Thanks for post.

BOOL CReportControl::OnFocusChanging(CXTPReportRow* pNewRow, CXTPReportColumn* pNewCol) {

//it was no checking for pNewRow = NULL !!!

CXTPReportControl::OnFocusChanging(pNewRow, pNewCol);

// apply changes

CXTPReportRow* pFocusedRow = GetFocusedRow();

if (pFocusedRow && pFocusedRow->GetType() == xtpRowTypeHeader &&

pNewRow && pNewRow != GetFocusedRow() && m_pFocusedRecord && pNewRow->GetType() != xtpRowTypeHeader)

*(CMessageRecord*)m_pFocusedRecord = *(CMessageRecord*)pFocusedRow->GetRecord();

UpdateRecord(m_pFocusedRecord, FALSE);

}

Now it works properly. Sample source in SVN updated
