Disable MRU file list

[Haakon S]

I have a MDI application where I want to have only one open document at any given time. There are several different types of views, so it therefore gets confusing with many open documents as well. So, thanks to a helpfull CPian I eventually managed to block OnFileOpen() and OnFileNew() if a file is already open. But the MRU list is still active. How can I disable it if I don't want it to show up? Haakon S.

Change the call to LoadStdProfileSettings() in your application's initialisation function to LoadStdProfileSettings(0). Regards, Jason Wilden.

Thank you for pointing in the right direction. But I'm not entirly happy with your proposal. I want to retain the MRU list if no file is open, and to disable it only when there is an open file. Calling LoadStdProfileSettings(0) will do away with the MRU list altogether. Anyway, I've discovered that there is something called CRecentFileList::UpdateFileList(). I'll do some scruteny here. Regards, Haakon S.

You could also delete it from the menu in the resource editor. Best regards, Alexandru Savescu

To eliminate the menu items, simply remove the ID_FILE_OPEN, ID_FILE_NEW and ID_FILE_MRU_FILE1 menu items from the the menu associated with you document template, but leave them in the default menu IDR_MAINFRAME (which is used when no document is active). You will also need to add a pair of ON_UPDATE_COMMAND_UI() handlers to your CDocument derived class to disable the ID_FILE_OPEN and ID_FILE_NEW commands when a document is active (this will prevent them being invoked via toolbar buttons or accelerator keys). When no document is active, you'll get the default behaviour (they will be enabled, since a handler function is defined). Stephen C. Steel Kerr Vayne Systems Ltd.
