You'll need to use the 'indexof' and 'substring' functions. 'indexof' finds the excact text that you want (eg. ) and returns it's numerical position in the string. You can then use this value with 'substring' to cut out the info that you want and place it in a new variable.
<BR>
<BR>More info, including a couple more functions that you'll need, and some examples here:

You'll need to use the 'indexof' and 'substring' functions. 'indexof' finds the excact text that you want (eg. <title>) and returns it's numerical position in the string. You can then use this value with 'substring' to cut out the info that you want and place it in a new variable.

I whipped up this sample application for you to explain the string searching using looping structures in vb. In this tiny program, you enter the Esato URL, ad it will tell you the topc ID.

On the rapidshare page that opens click the 'free' button near the bottom of the page, I will email you the file in any case by this evening. You can use this same method for an html doctype, just parse the html to text, but as I said this isn't the most efficient method, ideally you could make a class which would search only via the line number on the html page. If you are using 2005, there are system.xml, and system.web classes where you could make a repeating node element and search.
