我是为了学习C++，我已经打了一下一个绊脚石建立在VS2010一个简单的MFC的文本编辑器....调试断言错误viewrich.cpp
也就是说，虽然一切编译。当我在调试模式下运行程序时，它给了我一个“调试断言失败”错误在viewrich.cpp的行151，156和1875，它是VS2010的MFC的一部分。
线151和156下面的代码中：
int CRichEditView::OnCreate(LPCREATESTRUCT lpcs)
{
if (CCtrlView::OnCreate(lpcs) != 0)
return -1;
GetRichEditCtrl().LimitText(lMaxSize);
GetRichEditCtrl().SetEventMask(ENM_SELCHANGE | ENM_CHANGE | ENM_SCROLL);
VERIFY(GetRichEditCtrl().SetOLECallback(&m_xRichEditOleCallback)); //LINE 151
m_lpRichEditOle = GetRichEditCtrl().GetIRichEditOle();
DragAcceptFiles();
GetRichEditCtrl().SetOptions(ECOOP_OR, ECO_AUTOWORDSELECTION);
WrapChanged();
ASSERT(m_lpRichEditOle != NULL); //LINE 156
return 0;
}
线1875年是下面的代码中：
void CRichEditDoc::SetTitle(LPCTSTR lpszTitle)
{
COleServerDoc::SetTitle(lpszTitle);
CRichEditView *pView = GetView();
ASSERT(pView != NULL);
ASSERT(pView->m_lpRichEditOle != NULL); // LINE 1875
CStringA strAppName(AfxGetAppName()), strTitle(lpszTitle);
pView->m_lpRichEditOle->SetHostNames(strAppName.GetString(),
strTitle.GetString());
}

任何帮助将不胜感激。
你解决了吗？如果是的话，你还记得吗？ – manuell
