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
its possible to set the webbrowser cookies as same than httprequest cookies.
Private Sub lol() Dim request As HttpWebRequest = DirectCast(WebRequest.Create("http://login.ijji.com/postLogin.nhn"), HttpWebRequest) request.CookieContainer = cokie
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 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...?
I'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 a webbrowser control in my program and what I want to do is to delete all the cookies stored in my computer.The problem is that for example I'm in some site, and then I decide I want to delete all the cookies, so I do it by the command "Kill()" but the problem is that the cookies remain and this site still can recognize me, and to complete the kill command I need to close my program and enter it again.The webbrowser control uses Internet Explorer, and I think when you enter IE it somehow loads all the cookies into it so if you delete your cookies, they remain there.So I'm wondering how can I delete my cookies, completely delete them without the need to close my program and enter it once again.
I'm trying to delete cookies from my webbrowser control with this code: Form1.WebBrowser1.Document.Cookie.Remove(0, (Form1.WebBrowser1.Document.Cookie.Count - 1)) I think this works (not sure how to check) but if my webbrowser doesn't have ANY cookies yet, it shows this error: System.ArgumentNullException was unhandled
So basically, If my code is correct, I need some sort of error handling to check that there are cookies (if that is the issue?). I tried this code but it shows the same error: If Form1.WebBrowser1.Document.Cookie.Count > 0 Then
Form1.WebBrowser1.Document.Cookie.Remove(0, (Form1.WebBrowser1.Document.Cookie.Count - 1)) End If
Suppose I have webbrowser in mine form..Is it possoble to capture only the cookies create by mine webbrower..suppose before starting the project,in mine cookies folder there are cookies names cookie1 & cookie2....Suppose after the project run.cookies created by mine project are named cookie3 & cookie4...I want to delete cookie3 & cookie4 only..

I been trying to do this for days can't find a way to do that,ok so for example if you ahead and login into hotmail.com navigate somewhere like "bing.com"
clear cookies with something like For Each cookieFile As String In IO.Directory.GetFiles(Environment.GetFolderPath(Environment.SpecialFolder.Cookies), "*.txt")
I need to make 3 webbrowser (using the default webbrowser control) in my application, but I need them to use separate cookies. I want them to run independently. (ex : I put 3 webbrowser in my application, if I log in a site with a webbrowser, I'll be logged in the 3 webbrowser. I want that only one webbrowser will be logged in, not 3.)
I'm making a webbrowser for the pc's on my school, but I want to clear cache & clear cookies everythime someone exit's the webbrowser. Is there a simple code for it?
After I send a post request to a site/forum and successfully logged in, 1) How do I save/read the cookies so that when I visit other sections of the site/forum I remained logged in? Eg. I want to login to a forum and read a thread that only forum members can read.
Also, when I log in in the web browser tool (GUI) of vb.net, the cookies seems to be saved by the browser. Those cookies are also shared by Internet Explorer browser. 2) Is there a way to get the cookies from the web browser tool or Internet Explorer so I don't have to login and read/save the cookies programmatically?

I am trying to have a DateTime variable which is in a MM/dd/yyyy HH:mm:ss format convert to dd/MM/yyyy HH:mm:ss. I am using VS2008 Pro, and when I create a var:
dim dt as datatime = datetime.now It automatticlly defaults to MM/dd/yyyyy. No matter if I convert, parse, use globalisation or anything... convert to a string, which works with dd/MM/yyyy, but the minute i move it to a DateTime var type it goes back to MM/dd/yyyy I need to use this date/time to insert into a MS SQL Database and the colume is datatime type. But also is part of the app.I do not want this to be a string, I can do that, but I do need it to be a datatime in the correct format (dd/MM/yyyy HH:mm:ss)
I'm having an issue trying to pull information from a specific website. I've asked about this once before, but had no luck through searches or responses.In a nut shell, the issue I'm having is trying to pull information from several URLs from a site.When I load the first URL and pull the information, it works just fine. But if I want to pull another from that same site, it acts like it is loading, but doesn't pull the information. In order for me to gather that information, I have to restart the program, but that beats the purpose.So, I wanted to see if the issue was related to cookies or something else the webbrowser control creates when loading a site. If this is the case, I'd like to clear out this information, or at least try it, after each time it pulls the information from the site.
I have a simple exe that loads a page from my site in a webbrowser where users need to enter login details to get on a secure page. Now everything works ok, except I have to use php for this and yeah cookies. So, I want to know if it's possible to set a special location for the cookies, since as some members report, they clean the cookies daily and this makes my exe "forget" that they are logged in. Any way to store cookies on same location with the exe so it won't get deleted by 3rd party tools like ccleaner or so.
Im new to visual basic but i have some experiance in other languages.I been trying to build an application that uses the webbrowser module.There is only 1 thing i cant find anywhere.in my app i use my browser to signup at a sertain webpage.This page remembers my login info.When i close my application and open it again and go to the same page i can login again.But when i switch forms and go back to the browser form it will automatical login for me.
My problem is I have code delete a cookie it deletes it perfectly but my webbrowser1 doesnt recognize that its gone unless I restart the app. I'm wondering how I could get the webbrowser to restart (not refresh) or any way to get it to recognize the cookies no longer there?
I am trying to get the source code from a webpage. The WebBrowser control is giving me the information that I am looking for. However, I want to use HttpWebRequest, but its giving me different source code than the WebBrowser DocumentText. How can I get the same source code as WebBrowser using HttpWebRequest?
HttpWebRequest Code: Dim request As System.Net.HttpWebRequest = System.Net.HttpWebRequest.Create(url) request.KeepAlive = False request.Timeout = 10000 Dim response As System.Net.HttpWebResponse = request.GetResponse() Dim sr As System.IO.StreamReader = New System.IO.StreamReader(response.GetResponseStream()) Dim sourcecode As String = sr.ReadToEnd()

i am trying to make a webbrowser in VB2010, but one major roadblock that has been in my way for a while, is the fact that i can't get my bookmarks bar to work
i have no code to show you and i am completely open to ideas as long as i use a toolstrip just make sure that the bookmarks work and they are Saved when the program is closed and opened again.
Notes:
instead of "WebBrowser1" use: " CType(TabControl1.SelectedTab.AttachedControl.Controls.Item(0), WebBrowser).PutWhateverHere() "
(i am using a dotnetbar tabcontrol so i need the "AttachedControl")
the toolstrip i am using in this case is called "BookmarksBar" so please don't use "ToolStrip1"
