sorry about the repost. I have not had a response from yesterday: original post: http://www.aspmessageboard.com/forum/ASPPlus.asp?M=492601&T=492601&F=36&P=1 I run an Intranet and have the following problem.... I have a drop down list that has option values like <option value=http://aspmessageboard.com/archive/index.php/"username&#124hash-password">Persons Name</option> (Nothing sensitive so I am not worried about having the user/pass visible in the code) I want to have a single click login to UPScampusship.com so I can minimize the number of usernames and passwords 100 employees need to remember. **It is not the UPS website, but a special UPS site for large customers. Unfortunately the UPS site has some .Net tools, but the UPScampusship site does not: 1)User selects name and clicks submit from home page of Intranet 2) data is posted to another intranet page where the username and password are split, loaded into an array, and have the password unhashed. 3) the receiving page turns around and takes ary(0) <-- username and ary(1) <--password and auto-posts to the remote site via https. 4) the data would be posted to the login form process page of UPS and the user would be at this third party site, not on a intranet page-scrape. I can do steps 1 and 2, but am having the worst time figuring out how to post the data to this other site without screen scraping. In other words I want to auto-post the data and have the new site load in the window not using screen scraping. Is this even possible in .Net? I have scoured google and groups.google for several hours looking at snips of code that almost do what I want it to, but all seem to be screen scraping, which I do not want. I have also tried to understand the .net class explorer examples to no avail. I'm sure it is simple, at least in classic asp using the MSXML parser it was simple. Any ideas? I had one person reply with "what about using a web service". My response was: "I don't think a webservice will solve my problem because the remote web site is a third party site and that still does not help me understand how to auto submit the username and password. I just want to know how to auto-post form variables to a third party site so I can log in with one click of a button, without having to have 50 people remembering their usernames and passwords. In classic ASP you could use the MSXML parser to do a post to a remote site. I can't seem to figure it out in asp.net. the scenario is that the user selects their location, user clicks a button on my site, username and password are passed to another page to do the split, and then auto submit to form action login page of UPS. This is the closest I can get using the following code: Dim req as System.Net.HttpWebRequest Dim res as System.Net.HttpWebResponse Dim sr as System.IO.StreamReader Dim s as System.IO.Stream Dim b as byte() '--notice that the instance is created using webrequest '--this is what microsoft recomends req = System.Net.WebRequest.Create("https://www.upscampusship.com/login2.asp?qD=default") 'enncode the form data string into a byte array b = System.Text.Encoding.ASCII.GetBytes("LoginName=asdfasdf&UserPwd=asdfasdf") 'username and password purposeley written this way so I am not giving it out on the Internet :O) 'indicate that you will be posting the data req.Method = "post" req.ContentType = "application/x-www-form-urlencoded" 'send the form req.ContentLength = b.Length s = req.GetRequestStream() s.Write(b, 0, b.Length) res = req.GetResponse() 'read in the page sr = new System.IO.StreamReader(res.GetResponseStream()) Literal1.Text = sr.ReadToEnd '--tidy up sr.Close() res.Close()
