Override the MRU open command

I have customized my OnFileOpen and when I open the database, in this case, I add the file to the MRU list using AfxGetApp()->AddToRecentFileList(lpszPath);

How can I override the MRU open command? I have tried to add a handler for ID_FILE_MRU_FILE1 but that only works on the first MRU file. I must override the MRU open command because I can't use the supplied function, my app crashes.

Any ideas?

Hi Slask,

There are predefined id's ID_FILE_MRU_FIRST to ID_FILE_MRU_LAST.

You could create one single message handler for them using ON_COMMAND_RANGE (unfortunately cannot be created via ClassWizard, see help).

hope that helps,

Hi Zoppo!

Got it to work thank you. Perhaps you can help me out, how can I get the filename selected in the MRU list now that I catch the message. What's the easiest way? Do you know?

Hi,

I think U can copy the same code for other files also. Let us say 4 MRU files are allowed. Then add command handler for
ID_FILE_MRU_FILE1

Then copy the same code Now in *.h file declaration
      afx_msg void OnFileMruFile1();
      afx_msg void OnFileMruFile2();
      afx_msg void OnFileMruFile3();
      afx_msg void OnFileMruFile4();

and in *.cpp message map
      ON_COMMAND(ID_FILE_MRU_FILE1, OnFileMruFile1)
      ON_COMMAND(ID_FILE_MRU_FILE2, OnFileMruFile2)
      ON_COMMAND(ID_FILE_MRU_FILE3, OnFileMruFile3)
      ON_COMMAND(ID_FILE_MRU_FILE3, OnFileMruFile4)

Then add other three functions as(including for first)
void CSDIWithProgressView::OnFileMruFile1()
{
      AfxMessageBox("file1");

}

void CSDIWithProgressView::OnFileMruFile2()
{
      AfxMessageBox("file2");

}

void CSDIWithProgressView::OnFileMruFile3()
{
      AfxMessageBox("file3");

}

void CSDIWithProgressView::OnFileMruFile4()
{
      AfxMessageBox("file4");

}

Something like that u have to do.

try it out.

Hi slask,

seems that CWinApp has an (undocumented) member CRecentFileList* m_pRecentFileList. Just use it's operatot[] to get an indexed string from it.

Thank you very much Zoppo. Made it work using the following:

void CMainFrame::OnFileMru (UINT nID)
{
CString strFile;
CRecentFileList* pList = ((CMediaApp*)

AfxGetApp ())->GetRecentFileList ();
VERIFY (pList);

UINT nStringId = nID - ID_FILE_MRU_FIRST;
strFile = pList->m_arrNames[nStringId];
}

Zoppo

seems ok, but BTW you do not need to cast the return from AfxGetApp() to CMediaApp...

have a nice day ...

I must cast the AfxGetApp, since the function GetRecentFileList is a function that I wrote. I couldn't get a pointer to m_pRecentFileList any other way since it is protected. If I don't cast I get an error saying that GetRecentFileList() is not a member of CWinApp.....

oh, uuups, sorry, just did not read the whole line, excuse my thoughtless comment...
