vb.net desktop app using a con.fig file

That somehow doesn't sound right to me. Check if file is read-only. If yes, remove that flag.

 

Also, you are again going back to app.config. I believe, the file to be changed is .exe.config

 

Can you please confirm. I always fail to understand why people do not properly respond to each of the points raised in the original post.

Once a user signs on to their computer, I try to change the values in the app.config file. The permissions are locked.

I am not 100% sure about this, however, please follow along and TELL ME if it is working / not working.

Change the value you want to change and save the text file.

 

Run your exe file and it will read the changed value.

I have an app.config file and has a value like has some of the following information:

I read and re-read your question 3 times and failed to understand what you are trying to say / achieve.

 

Could you elaborate a bit, please. Give some example, code sample, etc.
