MFC创建程序的问题

俺就是在用MFC创建命为CEditApp后，在CEditAppDoc.cpp中直接加了以下代码
void CEditAppDoc::SetModifiedFlag(BOOL bModified /* = TRUE */)
{
CString strTitle = GetTitle();
CString strDirtyFlag = " *"; // note space before the ’*’
// so we don’t break Save As dialog
if (!IsModified() && bModified)
{
SetTitle(strTitle + strDirtyFlag);
}
else if ( IsModified() && !bModified )
{
int nTitleLength = strTitle.GetLength();
int nDirtyLength = strDirtyFlag.GetLength();
SetTitle( strTitle.Left(nTitleLength - nDirtyLength) );
}
UpdateFrameCounts();
CDocument::SetModifiedFlag(bModified);
}
然后在CEditView中直接加了以下代码:
void CEditAppView::OnChange()
{
// TODO: If this is a RICHEDIT control, the control will not
// send this notification unless you override the CEditView::OnInitDialog()
// function and call CRichEditCtrl().SetEventMask()
// with the ENM_CHANGE flag ORed into the mask.
GetDocument()->SetModifiedFlag(TRUE);
// TODO: Add your control notification handler code here
}
编译出现如下提示：

把你遇到的问题说清楚些！我创建了和你一样的工程，加入你写的代码，没有任何编译链接问题。所以，你先用MFC创建一个原始的单文档工程，名字为EditApp，先不要修改任何代码，编译试试有没有问题。如果没有，再加入你的代码看看结果。这样可以确定问题出在哪，有可能是你VC环境的问题。
