I created a small program. It works fine, but when I reload an already loaded and modified document that has been previously saved, I don't get a warning saying that I'm about to loose the modifications of my document nor do I get the reloaded document. The loading does not occur.
But things work fine if I load another document.

The warning should come when the current document is about to be closed. To have that warning you have to indicate that the document has been modified via the SetModifiedFlag(TRUE).

If your application is SDI OnNewDocument won't be called again when opening another document, OnOpenDocument will be. If you are doing something in OnNewDocument then it'll only be done once, that may explain your problem of the second document not being loaded.

Dear plaroche, I'm already using the function SetModifiedFlag(). My program is a SDI. This function allows me to get a warning when I attempt to close a document that has been modified since its last save. It also gives me a warning when I attempt to load another document if the current document has been modified since its last save. But it does not give me a warning when I attempt to reload the same document if the current document has been modified since its last save. The program Notepad does this fine. My program would not reload an already loaded and modified document. My program should not only reload the current document, but also should give me a warning that I'm loading an old version of the document. I hope you see the problem now.
Thanks for your answer anyway.

May I ask what is the behavior? Have you placed a breakpoint in OnOpenDocument() does it get called?

I did not override OnOpenDocument.
The behavior of my program is that when I try to reload an already loaded and even modified document, the document is not reloaded. Therefore I did not think overriding OnOpenDocument was the answer to the problem. But then again, I might be wrong.
I propose you to email me directly if you wish to, at stephane_eybert@prqa.co.uk

Dear Plaroche, I read in the book Inside Visual C++ that MFC does not handle the functionality I am asking for. I don't know why such a basic capability is not taken care of by MFC. A solution to this well known problem (cf D. Kruklingski Inside Visual C++) should exist somewhere.
