I'm fairly new to C++ and was just wondering if it was even possible to write a program that could manipulate certain things in Google Chrome? For example, I would like to have a program that reads the current pages URL, changes part of it if necessary, and then reloads the page. Just wondering if there is a easy way of doing this?
I have ever written Chrome extensions but usually browser extensions are written in javascript (since the browser already has an interpreter).
You can find more info here: http://code.google.com/chrome/extensions/index.html
What you are looking for is javascript. I believe Chrome has a counterpart of greasemonkey as in Firefox, which could load your own javascript and perform tasks such as those you mentioned.
