I have a textbox and the text is automatically updated from a text file, I can also type into the textbox and save it to the file that updates it. How can I make it not append any of the lines I type in if they already exist in the saved file?

I am using readAllText and writeAlltext, should I try using something else such as streamReader or streamWriter?

Any help on this part of my code is appreciated....

Thanks vb5prgrmr ,

It does seem a little envolved but soon as I have time I will give it a try.

First off, I am new to programming, I dabbled a little bit in Quick basic a long time ago but have forgotten most of it. This is my first post so please excuse the newbie.

I am creating a program where the user can type in URLs and they get added to a text file. On another page I have a Rich Text Box that displays the URLs, but I am unable to figure out how to get each individual URL to open up in the default browser.
