Browser Creation
im no expert, but once you have saved all the right info, and set it so to send the right data, there shouldnt be to much trouble in making a simple one…
Have you tried googling this?
i just searched "creating a simple browser tutorial" in google (no quotes), it returned a list of nice looking replys…
I've done a simple tabbed web browser prog in C#, but never had to "handle cookies" or change the user-agent. If you do decide to use .Net for it, the WebRequest and WebResponse objects would probably give you the functionality for changing the user-agent. Since it's not clear what your goal is with "handling cookies", I don't really have any input on that.
Now, for the obvious question: Why doesn't FF with the User Agent Switcher extension work for what you're doing?
