I'm trying to make my application append to a simple log file when it executed and when it's closed. So far, so good (see code)
However, what I would like to do, is have future lines of text to be written on the next line instead of the same line. And possibly a date stamp.
I'm not quite sure how to implement this as far as syntax goes.
My.Computer.FileSystem.WriteAllText("C:log.txt", "Application was closed ", True)

I have found many pages referring to having the date be part of a txt file being created, but not like the way I need. Having said that, this is what I've got.. [code] I read a page on working with txt files and learned what I could from it. It said to use the method in the beginning of my code for creating the file. It works great, but I would like to have a new file name everday, hence the date being integrated. So even if program was running, when midnight hits, a new txt file is created and new entries are written to that file. But I can't even get the date to be put in there. Everytime I try to make this work by using methods I read about in other pages, I get a syntax error, or a warning saying an end of statement is expected. I'm not sure those methods are compatible with what I've already got going.I was actually trying to store these values in a database, and I got real close I think, but I couldn't get any help to fix my problem so I'm trying to write to daily txt files instead. url....

I want to append a text file with items from a listbox. I tried to search for a code to do that, but couldn't find anything(most likely I don't know what I am looking for). But I wrote this code and got it to work, but after looking at the code, it looks sloppy and I'm sure could have bugs I didn't catch....my question is, is there a better code than the one I made, or will my code work fine. I am eager to write code correctly, not just get the code to work.
