Undocumented Call

This is the only way I found to create a CView-derived child window inside
another CView-derived
window which is part of a document/view SDI app.  But, I believe
CreateObject is undocumented.
Is that so?  (I'd like to avoid having to do that).  If I can't create my
CView-derived child
window in this manner, what other ways are there?

Here's the code:

void cTCView::OnInitialUpdate() 
{
	cBaseView::OnInitialUpdate();

	CCreateContext context;

	context.m_pNewViewClass = RUNTIME_CLASS(cTCView);
	context.m_pCurrentDoc = GetDocument();
	if (context.m_pCurrentDoc != NULL)
		context.m_pNewDocTemplate = context.m_pCurrentDoc->GetDocTemplate();
	else
		context.m_pNewDocTemplate = NULL;
	context.m_pLastView = this;
	context.m_pCurrentFrame = NULL;

	CWnd* pWnd;
	pWnd = (CWnd*)RUNTIME_CLASS(cTabContent)->CreateObject();
	ASSERT_KINDOF(CWnd, pWnd);
	ASSERT(pWnd->m_hWnd == NULL);

	DWORD dwStyle = AFX_WS_DEFAULT_VIEW;
	pWnd->Create(NULL, NULL, dwStyle, CRect(0, 28, 800, 800), this, 1, &context);
}

TIA,

Linda

It isn't poorly documented, it's just poorly indexed.  You can find 
documentation of it on the topic that documents CRuntimeClass.
