Using VB to download HTML page.

In Visual C++ I know how to connect to an HTTP server and download a given page. I usually declare an internet file object, do the necessary connections and then read through the file line by line.

How would I accomplish this in Visual Basic? I need some example code, please, for a function that might take in a URL, connect to it, and then read through the source code line by line.

(This is for data mining purposes, by the way. I chose VB over VC++ because of better string handling capability).

Thanks very much!

VB better than VC for string handling ???? Please note that i'm VB but i think VC is stronger for strings.

Anyway, simply put an INet control to your form, and do an OpenURL ( htmladdress ) to retrieve the data.

you can use the webbrowser control to do this:

WebBrowser1.Navigate "http://www.microsoft.com"
While WebBrowser1.Busy
    DoEvents
Wend
MsgBox WebBrowser1.Document.body.innerHTML

or
msgbox webbrowser1.document.body.innertext
