Paint UI with mix of themes

I want to have the bulk of my UI rendered with the CXTPOffice2003Theme, but selectively apply custom themes to other items, such as a toolbar here and there.

For example, I have an MDI child window with a CXTPToolbar attached which needs to be rendered with my custom theme. In this window's CChildFrame::OnCreate I tried the following, where CMyCustomTheme inherits CXTPOffice2003Theme and does some custom painting:

CXTPCommandBars* pCommandBars = CXTPCommandBars::CreateCommandBars();
pCommandBars->SetPaintManager(new CMyCustomTheme());

VERIFY(m_wndToolBar.CreateToolBar(WS_VISIBLE|WS_CHILD|CBRS_T OOLTIPS, this));
VERIFY(m_wndToolBar.LoadToolBar(IDR_CHILDFRAME));
m_wndToolBar.SetCommandBars(pCommandBars);

It worked, but I get an access violation when I mouse over a control in the toolbar. What's going on here? Is it a good idea to CXTPCommandBars::CreateCommandBars() again after the toolkit has initialized? Is the toolkit capable of supporting this?

I'm evaluating the toolkit, so the lack of source code is not helping.

on the subject of CXTPCommandBars::CreateCommandBars

what do you have to call to free the destroy the object that is returned by that call ?

I call CXTPCommandBars::CreateCommandBars in my dialogs OnCreate handler, and want to get rid of the allocated memory in its OnDestroy handler.

do I just call "delete m_pCommandBars" ? or maybe "m_pCommandBars->InternalRelease()" ?

which is correct ?

Thanks Fred

you cannot use "delete m_pCommandBars"!

because it won't compile, destructor is declared as protected

PS: using 9.51 here
