Just picking up the 19.2.0 update and integrating it into a number of applications I manage, and I am getting a consistent crash in all the applications which use it. I am creating a property grid control in my application with standard code which has been there for many years:
if (!m_wndPropertyGrid.Create(CRect(0, 0, 10, 10), this, 101))
{
TRACE(_T("Failed to create property grid control window\n"));
return;
}
m_wndPropertyGrid.ShowToolBar(FALSE); ...
and I am now getting a crash down in the bowels of CJ Toolkit Pro 19.2:
CXTPPropertyGridView& CXTPPropertyGrid::GetGridView() const
{
if (NULL == m_pView)
{
m_pView = CreateView();
m_pView->m_pGrid = (CXTPPropertyGrid*)this;
}
CXTPScrollablePropertyGridListBox* pScrollableView =
DYNAMIC_DOWNCAST(CXTPScrollablePropertyGridListBox, m_pView);
if (NULL != m_pView)
{
CXTPPropertyGridView* pEmbeddedView = DYNAMIC_DOWNCAST(CXTPPropertyGridView,
pScrollableView->GetControl());
if (NULL != pEmbeddedView)
{
return *pEmbeddedView;
}
}
return *m_pView;
}
pScrollableView is a null pointer in the above code and then the code attempts a call to pScrollableView->GetControl and promptly crashes. The call stack I have is as follows:

I have also tried rebuilding 19.2.0 with the new XTP_SKINFRAMEWORK_USE_LEGACY_API_HOOK preprocessor macro but get the same crash.
This looks like some issue introduced in the new 19.2.0 release. BTW, I have tried the PropertyGrid -> GridSample sample but there are no crashes there.
Is there some extra initialization or setup code which I need to avoid this issue?
Any ideas?
