How do I implement history for a web browser in c#?

[Kyph4n]

I'm not familiar enough with c# to have a good idea of how to ask this, but how do I take the text from the address bar and input the strings into a list that can be accessed somehow?

 

I would imagine doing something involving taking the string with the event "Text update", but I don't know how to do it and can't find anything online! (probably because I am unsure exactly what to ask)

 

Thanks

There are different Web viewers in C#, you'll have to specify which one you're using. I am however pretty sure that your URL bar is just an input field though.

 

You'll be wanting to look for something like webview.navigatedTo, you know as a general direction I'm sure there's something like that.

I'm using visual studio and making the web browser as a windows form application. I'm not sure what a web view is tbh

This is the current code I have, comboBox1 is the address bar, I need to somehow take the text from that and add it to a list somewhere within the browser but I have no idea how to do this.

The history could be a text file that you append to each time you switch urls I guess

Just do  CharlieBrowser. and see what suggestions IntelliSense gives, find if you can get the current URL, once you got it, and only if you got it, only then you navigate away. Ofcourse keeping track of previous URLs is easy at that point...

Please for the sake of the kittens use code tags...

That would work but I can see scalability being a concern (not in this context so much). You could take it a bit further and use a database such a SQLite for example and store history as well as settings. You could improve your architecture by defining a interface for data access (this would be your model) such that you hide your implementation detail away behind it. This way you could start with a text or XML file and later move to a database. The idea being that the behaviour (saving data somewhere) is consistent but the implementation my change - gives you a great place to add some unit tests.
