I'm wondering how to get the CWnd pointer which has been added in a CXTPTabControl object.
I add a CView object to CXTPTabControl as showed in the following codes:
BOOL CProductSysView::AddView(CRuntimeClass* pViewClass, LPCTSTR lpszTitle, int nIcon)
{
CCreateContext contextT;
contextT.m_pCurrentDoc = GetDocument();
contextT.m_pNewViewClass = pViewClass;
contextT.m_pNewDocTemplate = GetDocument()->GetDocTemplate();
CWnd* pWnd;
TRY
{
pWnd = (CWnd*)pViewClass->CreateObject();
if (pWnd == NULL)
{
AfxThrowMemoryException();
}
}
CATCH_ALL(e)
{
TRACE0( "Memory Overflow\n" );
// Note: DELETE_EXCEPTION(e) not required
return FALSE;
}
END_CATCH_ALL
DWORD dwStyle = AFX_WS_DEFAULT_VIEW;
dwStyle &= ~WS_BORDER;
int nTab = m_wndTabControl.GetItemCount();
// Create with the right size (wrong position)
CRect rect(0,0,0,0);
if (!pWnd->Create(NULL, NULL, dwStyle,
rect, &m_wndTabControl, (AFX_IDW_PANE_FIRST + nTab), &contextT))
{
TRACE0( "warning： Can not create\n" );
// pWnd will be cleaned up by PostNcDestroy
return NULL;
}
m_wndTabControl.InsertItem(nTab, lpszTitle, pWnd->GetSafeHwnd(), -1/*nIcon*/);
pWnd->SetOwner(this);
return TRUE;
}
m_wndTabControl is a CXTPTabControl type of member variable.
Now the pWnd pointer is a local variable. I want to know how to get its pointer in other functions.
many thanks

OK, I got it from the samples
the following code:
CView* pView = DYNAMIC_DOWNCAST(CView, CWnd::FromHandle(m_wndTabControl.GetSelectedItem()->GetHandle()));
ASSERT_KINDOF(CView, pView);
can get the right CView object pointer
then this post can be terminated
