Logging to open file

I have a small VB.NET application that captures left clicks, right clicks
and key presses and automatically logs them to a csv file every 1 minute.
The issue is that if I want to look at the log file, I get an error because
the app is trying to write to the log file and it is open.

How can I circumvent this issue?

Thanks,
Drew
 
When you look at the log file, are you opening it for read or for write?

I am opening it in Notepad, so I guess that I am opening it for writing...
How should I review this log while the program is running?

Do you want me to post all the code?

Thanks,
Drew
 
Hello Drew,

How are you doing?

Two ways to get out of this problem:
1) Copy the file and then open the copied file.
2) Create your own File reader in which you open a connection to the text
file in a ReadOnly mode.
And for this open a filestream instead. You can pass
System.IO.FileAccess.Read to the constructor.
Then you can create a new streamreader to read from the stream.

I hope this is helpful.

Thanks

Basically, you should not open the file to view it with an *editor*, which
by definition will open the file for write. If you don´t find a tool that
can open a file to view it with read-only access, you can build your own.
The .NET framework has functions to open streams for read-only access. See
the docs about the Stream and derived classes.

Thank you for your reply. I will check out the functions that you mentioned
and see what I can do.
