How to create a file system / directory manager in VC ++?

Question

I am new to VC ++ and programming. I have a task in which I have to design a file observer in VC ++.

The problem is as follows:

I have to constantly monitor some log files; whenever a particular log file is deleted (this removal is performed by another program), I have to open the TextFile and write some data and a timestamp to it.

How should I do it? Please, help!

Answer 4

I highly recommend that you consider using here . This API is not 100% reliable, but this code does a good job of completing it. If your file traffic is local and not too frequent, it should work well for you.
