Accessing "in Use" Files == ?

[intruder]

Hmmm,

I recall discussing this with one of my development team a very long time ago.

I believe that you have to use the FileShare enumerator and specify Read or ReadWrite. If I remember correctly the default is None?

I also remember that diagrams had to be handled differently because they were image/bitmap class files. I did a quick Google and found this:



It certainly can be done as I distinctly remember using MS Word and it would warn you if someone else had a file open for editing and actually offered to make a copy of it for you.

As you gave a .txt file as an example I just ran a little experiment opening the same file in both notepad and wordpad. I could edit it in both at the same time...............last file saved "won"

Well the reason why the last file that was saved, won was because the lock was placed on it and the contents were written then the lock was removed. Now since there is no call back in word pad so it was not notified of the change. And so when the word pad file was saved, it overwrote.

I think the op is asking about accessing the file when a lock on it is present already. And by accessing I mean trying to write to it
