Implemetation of a simple DocView framework like MFC.

Sample Image - DocView_framework.jpg


This article explains the implementation of a simple Doc View framework in a WTL (version 7.5) MDI application. The sample project included with this article is a wizard-generated MDI application enhanced with my framework classes. I enhanced code from Gabriel Kniznik with a little bit closer to the MFC DocView approach, and there exists only one kind of document template - MDI Document template. This framework was written in a week, so I apologize for mistakes and unfinished solutions Smile | :) .

In this article is also participating Rodrigo Pinho Pereira de Souza, who made great enhancements to this framework (see the History section).


In the demo project, you can see how to integrate the framework to your own project. You have to make changes to CMainFrame, CChildFrame, CYourView, and create a new class CYourDoc. Do not forget to change the IDR_CHILDFRAME string to the form for MFC -> \nDocument\nDVF\n\n\nDVFSimple.Document\nDVF Document.

Below is a simplified class diagram of the framework:

It appears that ExtractSubString was coded assuming ANSI . I made a couple of changes as below & added the _T() macros as you said and a few more changes and it compiles with Level 4 & UNICODE. I no longer get the exception you mentioned.
BOOL ExtractSubString(CString& rString, LPCTSTR lpszFullString, int iSubString, TCHAR chSep)
	if (lpszFullString == NULL)
		return FALSE;
	lstrcpyn(rString.GetBufferSetLength(nLen+1), lpszFullString, nLen+1);
	rString.ReleaseBuffer();   //-- this was missing
	return TRUE;
