Question
How to gather info from a webpage in a VB.Net app
Hello experts;
I am needing code to do this: When a user presses a button, the application will "read" a certain webpage and return a string variable from a certain area of the webpage.... ie. the title.
For example: user presses button, and my variable is populated from the title of a specified webpage ( i.e. amazon.com.... which would return <title>Amazon.com: Online Shopping for Electronics, Apparel, Computers, Books, DVDs & more</title> )
So how can I get my app to "go get" the title of a webpage? I assume it can load the pages source and capture everything between <title> and </title>. But I cannot figure how to do this. Any help is appreciated.
thanks
DaveMon
