Getting And Posting With Webrequest And Webresponse
Apr 3, 2010I would like to search an online (internet) database and import the result in my own Windows program. As I understand from reading and searching I first have to do a get from the default (search) page to get the cookies for instance and then do a post providing the filled input fields and adding the previously collected cookies. So far getting the information seems to work but submitting the data back to get the actual search result doesn't seem to work. This is what I have so far: [code]Anybody that can point me in the right direction? I my assumption correct that I first have to do a Get and then Post the correct data back?
View 3 RepliesGetting The Website Status Using WebResponse?
Mar 15, 2009I am trying to write a little application that will help me monitor 8 websites sharing the same IP address.
The code that I am using to query the Status of the Websites is failing to report the correct status of the website; by status of the website, I mean, if it is accessible from any browser.
I got a timer that triggers the following
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
'Create a web request for site.
[Code]....
Basically the webresponse is supposed to turn the textbox5 color to "coral" if the website is up and running or accessible, and turn the textbox5 red if the website is down. What is happening is that all the time the timer is triggered, the text box5 turns coral or "good connection" even if I entered a website that does not exist, Then after 3 minutes I get and exception error that states: The operation has timed out.
Basically, I just need a way to query the site and interpret the response by turning the textbox5 to color red in case the website is inaccessible or down.

Use The Webrequest Webresponse Method To Test For The Existence Of A File?
Apr 2, 2010I'd like to use the webrequest webresponse method to test for the existence of a file.If the first file is there, then I want to test for the existance of the same filename with -1.htm appended to it. If that filename exists, then test for filname-2.htm This continues until the filename being tested comes back 404 error. At which point, the program does NOT blow up, but the do until loop stops and the code continues. I have to search for a link on each one of the pages found once I have determined how many pages there are.How do I test for a file and not have it blow up? It has to loop and it goes through at least once. this is code I wrote. Right now the page just keeps going and going. IE's little logo on the page tab keep going around in a circle like it's in an endless loop.
Dim fr As System.Net.HttpWebRequest

VS 2008 Submit Form Using HttpWebRequest
Oct 27, 2009The 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?

Jul 29, 2009This is the short instruction:
1) Make a single HTTP-POST request to the following URL in XML format.

VS 2008 HttpWebRequest/WebClient To Fill Forms?
Oct 28, 2010I'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)
