Code Example

How easy is the Web Control to use? Check out the following VB example below, which demonstrates grabbing an HTML file and displaying the data.

Dim Orderform As String

Http1.Timeout = 20000 'give it 20 seconds to complete

Http1.Url = "http://www.dart.com/" ' Specify the URL to GET

Http1.Get Orderform ' Send a GET request, Orderform will be filled with data

Text1.Text = Orderform 'The HTML code for the web site appears in the text box
