How to update a textbox item or a label while in a loop?
<p>So I have a desktop app programming in C#, vs2010. It just has 2 textboxes and a button, and what it does is, I want to enter a link to download a direct exe file in the first box, and when i submit it, while its downloading, how do I make the 2nd textbox show a percentage of the download.</p>

<p>If thats too hard to explain dont worry, what i'm specifically looking for is, for example if I'm doing a loop of some sort, like I have two listboxes with the same text files loaded and I want to loop through it to check for duplicates but while in the loop theres like a status type of think for example it could be saying "Checking", or "Scanning (password here)" or "Looking for (password) now..." etc.</p>
