You would be better off using this from the document and using
SetModifedFlag() and IsModified() functions. You can call the document from
the view quite easily (GetDocument()). Also, you could do this in the
OnClose() in the view as well. If you use SetModifiedFlag() then the
framework will ask the user to save as well when the document is changed.

oops, forgot the code. Here it is.

Z.K.

code:

void CTravelerView::OnInitialUpdate()

{

m_OptionsChanged = 1;

m_OptionsSaved = 0;

}

void CMainFrame::OnClose()

{

// TODO: Add your message handler code here and/or call default

CTravelerView *pForm = (CTravelerView *)AfxGetApp();

CString temp;

temp.Format("pForm->m_OptionsChanged = %d\npForm->m_OptionsSaved =
%d",pForm->m_OptionsChanged,pForm->m_OptionsSaved);

MessageBox(temp);

CFrameWnd::OnClose();

}

I have an application and I wanted to pop up a message box depending on
the value of a variable in the CFormView when the x is clicked on the
titlebar. I created a pointer to the CFormView from CMainFrm, but it
always displays the variables as 0 and not what I changed them to in
OnInitialUpdate. I am not really sure why this does not work, but I have
posted the code below if someone could tell me what I am doing wrong.
