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?

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.FileA ccess.Read to the constructor.
Then you can create a new streamreader to read from the stream.
I hope this is helpful.
Thanks
Mona

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.

Hi all,
I wonder if it is possible to change (temporarily) a built-in function
for logging purposes.
Let me explain:
I want to log all the 'open' operations, recording the file to be
opened, the "mode" (r/w/a...) and (possibly) the module which made the
call.
After that the 'open' can carry on following the standard built-in
path.
Possibly I don't want to have to modify the source of the application

I'm using the logging module for the first time. I'm using it from

Is this something I'm doing wrong?

I have an application that is running in an endless loop processing an

how everything works together) I can't seem to close the log file again
