How to log into webmail?

[Brett]

How do I perform a web form submission in a windows form and get the
submitted page into a variable? For example, I'd like to create a Win Form
that has a username and pass. Once the Win Form's login button is clicked,
it will log into a web mail account. I will parse the first page (message
list) and display it in another Win Form.

Thanks,
Brett

Replace the URL, "username" and "password" with appropriate values.

If the file read is in XHTML format, you can use the classes contained in
the 'System.Xml' namespace for reading information from the file.

I tried your code but only get the login page. It doesn't return the page
after login, which means it isn't logging in. I was trying the following
code but getting the same results:

Dim myclient As System.Net.WebClient = New System.Net.WebClient
myclient.Headers.Add("Content-Type", "text/html;
charset=ISO-8859-1")

Dim d As Byte() =
System.Text.Encoding.ASCII.GetBytes("us*********** ****@verizon.net&password=somepass&jsCapable=1&fra mes=0&LOCALE=en_US&VARIANT=")
Dim res As Byte() =
myclient.UploadData("http://netmail.verizon.net/en_US/agent/moblogin",
"POST", d)

Me.rtxtShowWebpage.Text = System.Text.Encoding.ASCII.GetString(res)

You can see above I'm submitting all the login page form variables. Is this
a cookie issue? How is that handled?

Thanks,
Brett
