Retrieve Values from Web Page (WebBrowser Control)
Allows you to retrieve values from fields (i.e. hidden fields) in a web page loaded using the WebBrowser control. Very simple function, but I've found it extremely useful. Please don't forget to leave a comment to let me know what you think! To call this function try this example: MyValue = GetWebValue(MyWebBrowser,"fieldname") Will return the value or nothing if not found.
