Hi,

Unfortunately it does not work because I'm trying to access a web page from a Windows form, the article is for accessing a web page from a web page.


Thanks,

Victor

Hi Victor;

This is the reason why I wanted to know what platform you wanted to get access to the Web page in a previous response.

From a Windows application you can download the web page as a string as follows.

Imports System.Net

Dim wc As New WebClient()
Dim Url As String = "http://www.eggheadcafe.com"
Dim result As String = wc.DownloadString(Url)

Open in new window

Hi,

I tried the code below but the web page does not appear.

Imports System.Net

 Private Sub Button17_Click(sender As System.Object, e As System.EventArgs) Handles Button17.Click
        Dim wc As New WebClient()
        Dim Url As String = "http://www.yahoo.com"
        Dim result As String = wc.DownloadString(Url)
    End Sub

If you want to open the page in a browser, call Process.Start with the address as parameter:
Process.Start Url

Open in new window

Hi Victor;

The code I posted will bring the web page in HTML format into a string variable, is that not what you wanted? If you want to display that in a Windows form you can use a web browser control.
