Result Thus the calculator using command array was created successfully

OBJECTIVE:
To create a editor using multiple document interface this has the serializing ability to store the data as separate documents.
PROCEDURE:
1. Run the MFC App wizard (exe) to generate c:\mdi
2. Select multiple documents in step1 of App wizard.
3. Accept all the default settings.
4. In the step 6 of App wizard select CEditView as the base class.
5. Press OK to finish the wizard.
6. In the mdiDoc.cpp whether the serialize function has the following statement
((CEditView*)m_viewList.GetHead())->SerializeRaw(ar);
This helps in storing data in the editor.
7. Using class wizard mao the WM_RBUUTONDOWN to CEditorViewID.
void CMDIView::OnRButtonDown(UINT nFlags, CPoint point)
{
char szTimestr[20];
CTime tm=CTime::GetCurrentTime();
sprintf(szTimestr,"its now %02d:%02d:%02d",tm.GetHour(),tm.GetMinute(),tm.GetSecond());
MessageBox(szTimestr,"is it time to quit yet",MB_OK);
CEditView::OnRButtonDown(nFlags, point);
}
8. The above coding will help to print the system date when the user presses the RBUTTONDOWN in each editor.
9. Compile and run the application.
10. The resultant editor will have all editing capabilities and loading capability.
