How does one post to an ASPX page using the WebClient when the form
name is required?


Could you be more specific?

Dim client As New WebClient

client.Headers.Add("Content-Type",
"application/x-www-form-urlencoded")
Dim myQueryStringCollection As New
System.Collections.Specialized.NameValueCollection

myQueryStringCollection.Add("username", "test")
myQueryStringCollection.Add("password", "tickle")

client.QueryString = myQueryStringCollection
Dim ResponseData As Byte() =
client.DownloadData("http://www.mytestsite.com/index.aspx")

From the code above I'm posting the "username" and "password" to the
"index.aspx" page and downloading the page ingo the ResponseData Byte
array. What happens if the index.aspx page has more than one form and
I want to post to a specific form OR if the index.aspx page is
specifically looking for a form name to via the request object??

How can I specifiy the form name when using the WebClient class to
post information to a page/form??

WebClient.QueryString gets/sets the query string. You are downloading from

http://www.mytestsite.com/index.aspx...assword=tickle.

You aren't POSTing at all, you're using a GET.

See a recent thread in this newsgroup called "Going crazy over HTTP Post
from class library". Make sure you read the entire thread!
