Hello,

sometimes, when I close my app, I got an ASSERT :

#ifdef _DEBUG
void CHandleMap::RemoveHandle(HANDLE h)
{
// make sure the handle entry is consistent before deleting
CObject* pTemp = LookupTemporary(h);
if (pTemp != NULL)
{
  // temporary objects must have correct handle values
  HANDLE* ph = (HANDLE*)((BYTE*)pTemp + m_nOffset); // after CObject
  ASSERT(ph[0] == h || ph[0] == NULL);
  if (m_nHandles == 2)
   ASSERT(ph[1] == h);    <<<<<<
}

The stack is like :

> mfc80d.dll!CHandleMap::RemoveHandle(void * h=0xb8012aca) Line 218 + 0x1e bytes C++
  mfc80d.dll!CDC::Detach() Line 122 C++

  STBSim.exe!CXTPDockBar::AdjustRow(CArray<CXTPToolBar *,CXTPToolBar *> & arrRow={...}, CPoint pt={...}, int nLength=1499, int bHorz=2, AFX_SIZEPARENTPARAMS * lpLayout=0x0012d564) Line 343 + 0x24 bytes C++
  STBSim.exe!CXTPDockBar::CalcDynamicLayout(int nLength=1499, unsigned long nMode=11, AFX_SIZEPARENTPARAMS * lpLayout=0x0012df88) Line 403 + 0x23 bytes C++
  STBSim.exe!CXTPDockBar::OnSizeParent(unsigned int __formal=0, long lParam=1236872) Line 460 C++
  mfc80d.dll!CWnd::OnWndMsg(unsigned int message=865, unsigned int wParam=0, long lParam=1236872, long * pResult=0x0012d884) Line 2004 + 0x11 bytes C++

It's a MDI app with 3 open documents / frame windows. 2 different doc types.

Any ideas ?

Thx �n advance,

Alex

Hi,

Do you have another thread that can cleanup MFC GDI maps?

Hello,

not really. I have only the main thread which resposible for the GUI.

There are other threads, but they are not gui related. BTW, they are not active anymore when the app is about to exit.

Do you think a parallel thread is causing the problem ?

Hi,

Difficult to say without any code :(

Send your mainfrm.cpp and full stack to support@codejock.com.
