 Topic: Bug in CXTOutBarCtrl::GetItemSizePosted: 01 October 2007 at 3:53pm |

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. |

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. |

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.

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

Where do I find the TaskPanel samples? They're not under my
Xtreme Controls v11.2.0\Samples\Controls folder. |

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