I think there is a problem with cookiecontainer (httpwebrequest)there are 2 main functions in my class, first getting a new form (a hidden token in form tag), and it should set the cookies (which not set) and then second function (doLogin) should login the form. why cookie is not set...?
View 2 RepliesI'm trying to log into a website using httpwebrequest but website tells me that cookies are not enabled. I do have this,
Dim cookieCont As CookieContainer = New CookieContainer
Dim Request As HttpWebRequest = WebRequest.Create(URL)
Request.CookieContainer = cookieCont
My knowledge of VB.Net is quite limited and I'm trying to jump in at the deep end, I'm trying to log in to a website (a game in which I play) that requires a username and password, they must be submitted used the POST method and then I need to be able to view the source of the page to obtain further useful data.
This is what I have at the moment and it isn't working for me.
Function postRequest()
Dim s As String = ""
Dim username As String = txtUserName.Text

1) How do I use cookies obtained from login to do subsequent requests? e.g. Login to a forum, then use the cookie obtained from login to access User CP and change settings.
2) How do I parse HTML via HttpWebRequest? Does mshtml work with HttpWebRequest? If so, how do I work with it? I thought of downloading the source code of the page I'm requesting into a richtextbox and do my stuff from there, but it sounds kinda impractical to me since I have to use regex to get the innertext of stuff (or not?).
i have an aplication that interacts with a http server, some tasks are performed using the web interface, but the the user has to use the application for some special features... i would like to make it "singe sing on", i was thinking about importing the IE cookies into the CookieContainer but i can't find any documentation on how to do this.
View 2 RepliesI'm trying to do a POST request but the website tells me that cookies are not enabled on my browser.

I'm new to VB and am using 2008 VB Express edition. I'm trying to access a webpage's html using HttpWebRequest and that page requires cookies or it sends me to a login page. I found code examples around the web and have written the following code:

I'm writing a program for my sister for a game which she plays online. It uses a WebBrowser control, and HttpWebRequest as well.The basic function is it searches through the website, we'll say the url is http://hersite.com/pet/* (don't follow the link lol it's just an example) where * is a number and this is how it searches.I use a for loop to cycle the numbers from a specified start to end, and use an httpwebrequest to fetch the html code, then process the string using InStr and .split()When I access the webpage using the WebRequest.Navigate, it takes me to the page correctly. However, if I fetch the source through the HttpWebRequest, it fetches the source of the login page, which the website redircts you to if you are not logged in.Is there a way to transfer the cookies from the WebBrowser to my HttpWebRequest?
Some examples:Get the HTML somewhere in here I need to add the cookie to the http requester, don't I?
Function GetHTML(ByVal strPage As String) As String
Dim strReply As String = "NULL"
Try
Dim objHttpRequest As System.Net.HttpWebRequest

I add cookies to a cookiecontainer using
cookCon.add(response.cookie)
After that, how do I get the cookie in the cookiecontainer?
I tried
cookCon(0) and cookCon.cookies(0).
