I am facing a strange problem with listbox. I need to scrab whois information. I used the following code to get source code of the whois query. It works fine if I use a textbox. But I need to use this for multiple url and therefore need to use lixtbox to loop through url list. Unfortunately when I use listbox1.selecteditem or listbox1.text it does not work. But this same code works with webbrowser.

What I would like to know is how to obtain form input elements during an httpwebrequest?
[Code]...
Is it possible to obtain these input elements during an httpwebrequest without having to view the html code?
Is it possible to get events of httpwebrequest? For example when I make a post request, then in the events procedure I should be getting something like this in the following order say
connecting to website
connected to website
posting request
request posted
waiting for response
receiving response
response received
disconnecting
disconnected
Or how to I implement something like this with the webrequest?
Im looking for tutorials on httpwebrequest and httpwebresponse. Im actually using chilkatsoft http which makes it quite easier.

Today I was just wondering how I would go about authenticating a HttpWebRequest to a certain site. I'm trying to get the Response from an order page to parse the HTML from it, however it always redirects to the login page when I try, even after assigning the credentials.

View 4 RepliesI have a crawling program that fetches urls to parse the html and came across an unusual error since I started this. For a specific set of urls from a site when fetching using HTTPWebRequest and HTTPWebResponse I get the error The remote server returned an error: (404) Not Found This is unusual since it works when pasting it in my browser. Not sure if code is needed to posted but let me know if so.

i have a weird problem: when i use httpwebrequest to download a string from a site, it says 403 forbidden, but when i try to acces the same string from any browser, everything goes normalcode to download string:

cmdreq = WebRequest.Create(Host & "/command.txt")

The below code allows me to login to a site using HttpWebRequest however I can't login to the site [URL] (which is the one I want to login to). At the bottom of the code I write the source to a file and upon opening it simply shows the login page.
After looking at the source I believe the issue is caused by the form calling a javascript funciton to actually submit the form when the 'Login' button is clicked. Has anyone had this type of situation in the past and if so what was the solution to get the form to submit?

i have a site that i would like to login using httpwebrequest.I have this code and added the correct part to post
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim postData As String = "u_name=" & TextBox1.Text & "&p_word=" & TextBox2.Text & "&login=Login"
Dim tempCookies As New CookieContainer
Dim encoding As New UTF8Encoding

If i enter the wrong login info it says bad login, but if i add the correct login info, it does not login, all it does is displays the login page again?

This is the short instruction:
1) Make a single HTTP-POST request to the following URL in XML format.
[URL]={password}&user={username}
2) The xml form field that is posted should be named "createorder".
I don't get the last part with naming the xml form field. What the xml form field means (stands for) in this context?
I'm using the following code to set the proxy on an HTTPWebRequest:
Dim proxy As New WebProxy("HOST:PORT")
...Then...
' Goto the final URL
request = CType(WebRequest.Create("[URL]"), HttpWebRequest)
request.Proxy = curProxy
[Code] .....
Now I put in a valid Proxy, don't run into any problems applying it, but IPChicken will always return my IP address, not that of the proxy.
I am using GET and POST webrequests and am trying to set the User-Agent.
Public Sub getpost(ByVal URL As String, ByVal method As String, ByVal postdata As String)
Dim request As WebRequest = WebRequest.Create(URL)
If method = "POST" Then
request.Method = "POST"
Dim byteArray As Byte() = Encoding.UTF8.GetBytes(postdata)

The above is what I tried to set the user-agent but it returns an error saying that I'm not properly setting it.

I'm looking for a way to fill in various website details using a HttpWebRequest/WebClient. I can manage it quite easily using an invisible WebBrowser control, by manipulating the HtmlDocument, but for some reason I just can't quite grasp the way I would do it with a HttpWebRequest/WebClient. I've heard both of these can potentially submit info using the UploadData functionality etc, but I'm missing specificsI've done a lot of searching on google just for a basic example to get me started, but the only one that LOOKED informative was written entirely in German.Take, for example, this website. Let's just say I wanted to automate filling in my username and password into their respective boxes and then pressing the "submit" button. How would I start going about this, and how do I get the resulting page? (I'm assuming cookies that the page creates will keep your next webrequest going)

View 18 RepliesI am having problems with copying from one listbox to another and keeping the paths of the files in the listbox's. At the moment i have two listbox's, listbox1 shows the list of files without the directory paths showing. Listbox2 is used to add items from listbox1 which work ok but what i need is to be able to preserve the directory paths to each file. how to do this and have searched high and low for a solution without any luck.
I have worked out one way of doing it but i think there is a better way of doing it as the reverse does not seem to work. So basicly i want listbox1 to list the files without the paths and pass it on to listbox2 so that the files can be copied to temp directory as they are being add to listbox2.
Below is my
