HI,
Sorry, it is part of Xtreme TaskPanel or Xtreme ToolkitPro only.

Where do I find the TaskPanel samples? They're not under my

Xtreme Controls v11.2.0\Samples\Controls

folder.

Hi,
 
Thanks.
 
Actually CXTOutBarCtrl is very obsolete class, I recommend you use CXTPTaskPanel instead. See Samples\TaskPanel\* samples.

My code set the currently selected item of a folder using SetSelItem while processing an OBN_XT_FOLDERCHANGE notification. This produced the apparently invalid state of m_nFirstItem < 0. Consider adding an ASSERT.

In fact, my application even crashes when I fix this bug.

For some reason, m_nFirstItem becomes less than zero, and the code is not safe-guarded against this. In PaintItems, there is a loop

for (int i = m_nFirstItem; i < nItemCount; i++)

that accessess items with index i, and this fails if nFirstItem < 0.

The code at lines 1833-1834 of XTOutBarCtrl.cpp (function CSize CXTOutBarCtrl::GetItemSize(const int iFolder, const int iIndex, const RectItem iType)) reads:

if (iIndex < 0 && iIndex >= pBarFolder->GetItemCount())
   return CSize(0, 0);

Looks like a logic problem, should be || instead of &&... This sometimes crashes my application, however, the sample works fine despite this bug.
