Hi, I have found a some error when set true to CXTPControlGallery::SetScrollBarAuto.

Here is sample code. (Used in "Codejock/Sample/Ribbon/RibbonControls/MainFrm.cpp")


// Create Inline Gallery
if (pTabGallery)
{
  CXTPRibbonGroup* pGroup = pTabGallery->AddGroup(ID_GROUP_INLINE);
  pGroup->SetControlsCentering(TRUE);

  CXTPControlGallery* pControlGallery = new CXTPControlGallery();
  pControlGallery->SetControlSize(CSize(192, 60));
  pControlGallery->ShowLabels(FALSE);
  pControlGallery->ShowScrollBar(TRUE);
  pControlGallery->ShowBorders(TRUE);
  pControlGallery->SetItems(m_pItemsFontTextColor);
  pControlGallery->SetScrollBarAuto(TRUE);       <<<<<<<<<< I just added one line code !!!
  pGroup->Add(pControlGallery, ID_GALLERY_STYLES);
  
  ...
}


// Now ScreenShot
Just only one item displayed and occurred Access Violation error when mouse move on gallery control.


// To-be ScreenShot



// CallStack






// Stange Codes
I think below codes are strange...

void CXTPControlGallery::RepositionCore(BOOL bCheckScroll)
{
CRect rcItems = GetItemsRect();

int x = rcItems.left;
int y = rcItems.top;
BOOL bFirstItem = TRUE;

int nCount = GetItemCount();

    // if item count is 10, m_arrRects will be set size too
m_arrRects.SetSize(nCount);
int nRowHeight = 0;

for (int i = 0 ; i < nCount; i++)
{
CXTPControlGalleryItem* pItem = GetItem(i);
m_arrRects.pItem = pItem;
m_arrRects.bBeginRow = FALSE;

if (pItem->IsLabel())
{
...
}
else
{
...
}
    // but breaked when i == 5 ...
    // m_arrRects[6] ~ m_arrRects[9] are will be null pointer!!!
if (bCheckScroll && y + nRowHeight + rcItems.top > rcItems.Height())
{
break;
}
}

y += nRowHeight;

m_nTotalHeight = y - rcItems.top;
}




Thanks.
