XTP 12.0 crash

what happens when you run the app in debug mode?

 

Did you perform a complete rebuild of the whole app in release mode. Sometimes this helped after upgrading the toolkit.

Perhaps you should enable debug in release build (create .pdb file). In this case you are able to locate the crash in source code (don't forget the toolkit too).

 

I think the class that cause crash is CXTExcelTabCtrl.

 

The function is : _DeleteItem(int nItem) use to  Cleanup by  CXTExcelTabCtrl::ClearAllItems()

BOOL CXTExcelTabCtrl::_DeleteItem(int nItem)
{

 const int cItems = (int)m_tcbItems.GetSize();
 if (nItem < 0 || nItem >= cItems)
  return FALSE;

 

// 20/05/08 :FIX: crash problem
#if 0
 // Remove the item from the string arrays.
 CWnd *pWndControl = m_tcbItems[nItem]->pWnd;
 if (::IsWindow(pWndControl->GetSafeHwnd()))
 {
  pWndControl->ShowWindow(SW_HIDE);
  pWndControl->SetParent(NULL);
 }
#endif

 

 SAFE_DELETE(m_tcbItems[nItem]);
 m_tcbItems.RemoveAt(nItem);
 if (m_tcbItems.GetSize() == 0)
 {
  m_bManagingViews = false;
 }
 return TRUE;
}

 

 

void CXTExcelTabCtrl::ClearAllItems()
{
 while (_DeleteItem(0))
 {
 };
}

 

CXTExcelTabCtrl::~CXTExcelTabCtrl()
{
 // Cleanup
 ClearAllItems();
 FreeButtonIcons();
}

 

 

Now when in comment a piece of code below,
