Introduction
The Most Recently Used (MRU) files list is standard feature of most Windows applications. This article describes how to add (MRU) support to Windows (SDI/MDI) application using the class CRecentFileList
. CRecentFileList
is a CObject
class that supports control of the most recently used (MRU) file list. Files can be added to or deleted from the MRU file list, the file list can be read from or written to the registry or an .INI file, and the menu displaying the MRU file list can be updated.
Using the code
Adding MRU to MFC SDI or MDI is actually not very difficult. I just add AddToRecentFileList
(LPCTSTR lpszPathName
) to CDocument
derived class which calls the add the path name to CWinApp
's CRecentFileList
(m_pRecentFileList
). I use SDI for this demo.
1. Iinclude afxadv.h to stdafx.h. This contains the class CRecentFileList
.
#include <afxadv.h>
2. Add AddToRecentFileList
to CDocument
derived class and use this function during opening and saving the document.
void CCMRUTestDoc::AddToRecentFileList(LPCTSTR lpszPathName)
{
((CCMRUTestApp*)AfxGetApp())->AddToRecentFileList(lpszPathName);
}
BOOL CCMRUTestDoc::OnOpenDocument(LPCTSTR lpszPathName)
{
if (!CDocument::OnOpenDocument(lpszPathName))
return FALSE;
AddToRecentFileList(lpszPathName);
return TRUE;
}
BOOL CCMRUTestDoc::OnSaveDocument(LPCTSTR lpszPathName)
{
AddToRecentFileList(lpszPathName);
return CDocument::OnSaveDocument(lpszPathName);
}
3 Add AddToRecentFileList
for CWinApp
derived class.
void CCMRUTestApp::AddToRecentFileList(LPCTSTR lpszPathName)
{
if (m_pRecentFileList != NULL) {
m_pRecentFileList->Add(lpszPathName);
}
}
