	Hi, I used AppWizard and created a MDI form view app then added the above code you mentioned and was not able to reproduce the problem. Make sure you check your dialog form view resource to ensure it is valid. Regards, Codejock Support

	In CDialog, everything is OK, but in CFormView, Debug Assertion Failed when I create CXTOutBarCtr . I think the reason is that we can't use "this" to point to a pParentWnd. you can try to add a CXTOutBarCtr in your sample-TabbedView.

	Hello, try to call OnInitialUpdate() of base class first. What line generates assert?

	void CSoftView::OnInitialUpdate() { CFormView::OnInitialUpdate(); m_softOutBarExpert.Create(WS_CHILD\|WS_VISIBLE, CRect(0,0,0,0), this,IXT_OUTLOOKBAR, OBS_XT_DEFAULT) //here generates assert }

	Then I followed the code to XTOutbarCtrl.cpp: BOOL CXTOutBarCtrl::CreateEx(DWORD dwExStyle, DWORD dwStyle, const RECT& rect, CWnd* pParentWnd, UINT nID, const DWORD dwFlags) { ASSERT(dwStyle & WS_CHILD); ASSERT_VALID(pParentWnd); //here generates assert if(!CWnd::CreateEx(dwExStyle, NULL, NULL, dwStyle, rect, pParentWnd, nID)) { return FALSE; } m_dwFlags = dwFlags; return TRUE; }

	Hello, You do something wrong. I create new project with CFormView as view, inserted m_softOutBarExpert.Create(WS_CHILD\|WS_VISIBLE, CRect(0,0,100,100), this,100, OBS_XT_DEFAULT); and CXTOutBarCtrl m_softOutBarExpert; all work as expected. Attach your project to check what you do.

	in release mode, it's OK, but in debug mode, wincore.cpp 626 line generates assert ASSERT(pWnd->m_hWnd == NULL); // only do once

	Hi, Problem that OnInitialUpdate called twice. Remove pWnd->SendMessage(WM_INITIALUPDATE); from CTabbedViewView::AddView. This line was in old releases of our sample. In last releases it was removed.
