Hi.
One of our customers got an exception in our application. I have analyzed the
problem. The exception comes in the function LoadCommandBars.
The user does not know what he exactly have done. But somthing like this: he
creates an customized toolbar, and he drags this toolbar out of the main
window. At the next start of the application the an exception is thrown
When i delete the registry settings of XTT it works again without problems.
Please help!

In the debug version i got an assertion (look at the arrow); pDC is zero!

CSize CXTPOffice2003Theme::DrawCommandBarGripper(CDC* pDC, CXTPCommandBar*
pBar, BOOL bDraw)
{
if (pBar->IsDialogBar())
return DrawDialogBarGripper(pDC, pBar, bDraw);

CRect rc;
pBar->GetClientRect(&rc);

if (pBar->GetPosition() == xtpBarFloating)
{
---> ASSERT(pDC);
CXTPFontDC font(pDC, &m_fontSmCaption);

The DrawCommandBarGripper was called in this function:

CSize CXTPToolBar::CalcDockingLayout(int nLength, DWORD dwMode, int nWidth)
{
CClientDC dc(this);
CXTPFontDC font(&dc, GetPaintManager()->GetCommandBarFont(this));
CXTPControlPopup* pPopupExp = NULL;

CRect rcBorder = GetPaintManager()->GetCommandBarBorders(this);

if (m_dwStyle & CBRS_GRIPPER)
rcBorder.TopLeft() +=
GetPaintManager()->DrawCommandBarGripper(NULL, this, FALSE);

The call stack looks like this:
