m_rptMessages.GetPaintManager()->SetFixedRowHeight(FALSE);

 

When I add a row that has text with carriage returns in it, it displays correctly in the Report Control.

 

If I hover over it with my mouse, however, it shows a tooltip window that has all the text on one long line.

 

CXTPReportControl::OnMouseMove calls pRow->ShowToolTip(point, &m_wndTip);

CXTPReportRow::ShowTooltip calls pTipWnd->Activate(TRUE, IsPreviewItem || IsIconView);

 

My report has not enabled previews nor is it in Icon mode.  It's just doing multi-line text, so it results in passing false for the second parameter to Activate which appears to control whether tooltips are multiline.

 

Is there a way around this?  This appears to be a bug to me.

 

In AddSampleRecords, modify one of the subjects to have a \r\n in it:

    strSubject = _T("Comment Added: memory leak in OnEndEdit()?\r\nThis is very bad!");

 

In OnReportcontrolMultilinesample():

Comment out all the code that sets DT_WORDBREAK.

Comment out setting m_bUseColumnTextAlignment = TRUE;

 

Run App.  make window small enough so that Subject gets truncated with "...".

Hover over it, see there's a tooltip.

Select "Report Control | Multiline Sample".

 

You should see your subject now go to two lines.

Hover over it now.

 

2 problems:

* Even though it's no longer truncated, there's still a tooltip.

* The tooltip does not respect the \r\n, it's all on one line.
