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
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.
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 have a problem with WebBrowser control and cookies.First of all what happens when one navigates in a normal Web browser (IE9 in my case): open page
I enter my username / password,
I leave the checkbox "Stay signed in" unchecked and click "Sign in",
IE9 opens my GMail page with all my mails listed. That is OK.
1.2. At the top of GMail page there are a lot of links like "Calendar", "Documents", etc.
When I click the "Documents" link, my documents page is opened in a separate tab in IE9. No additional login information as name / psw is asked. This is fine too.Now, what happens when I repeat all that in WebBrowser control (I have created a very simple VB.NET application with single WebBrowser control in it).
2.1. In form load event the following code is executed:
Private Sub MyForm_Load(sender As System.Object, e As System.EventArgs) Me.MyWebBrowser.Navigate("http://www.gmail.com") End Sub
2.2. I enter my GMail login information (name and psw) in WebBrowser control,
2.3. When I click the "Documents" link, a new instance of IE9 is opened,
2.4. Instead of showing a list of my documents, Google asks me to login again in an IE9 window. Why? Why I have to enter my credentials again?I think there is something wrong with cookies and they are not set correctly in a step 2.2.
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'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 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 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 writing a few web based apps which will require a webbrowser extension. I have already used the IE webbrowser control that uses the trident web rendering engine. I believe this is MSHTML.DLL? Anyway, some of the users of my programs have complained of a few things. Particularily,
1. It seems to be a slow browser, at least compared to other rendering engines out there (webkit and gecko are 2 known ones).
2. On the developer side, it seems to be low in features. The features are sufficient in most cases, but there are some "special" things that I need.
3. It has VERY low HTML (and especially HTML5) compliance.
My question is, how much work would it take to use a different engine (such as webkit .net, which I HAVE heard of) and be able to distribute it easily. Or, if you guys feel ambitious, we could try writing a brand new engine ourselves. I know how big of a job it is, and frankly, I have no clue where to begin. I would just like your thoughts and opinions on the matter.
i have created an app to load an access database into a datagridview, which contains web urls. When button is clicked it webbrowser1 navigates to each url and each webpages document.inertext is put into textbox. This all work fine but after a while the webbrowser navigation becomes increasingly slower.
For Each RW As DataGridViewRow In Me.DataGridView1.SelectedRows '''''''''''#######cell values into strings ########'''''''''''''' If RW.Selected = True Then Dim domain As String
Ive tried to edit option on the webbrowser control, example javascript enable/disable. but found out that it uses IE's option and cannot be changed.So my question is: Is there a way to do a "webbrowser" without using the WEbbrowser control that is based on internetexplorer? If it is, can i change option example flash and so on?
I have a regular application form with a WebBrowser control.I have strung together a .htm file (from a regular text file) which I then assign to the WebBrowser control. In the html file, I have filenames mentioned.I am trying to string together the html in such a way as to give a clickable link or button that will parse into html and open the corresponding file in another WebBrowser control in VB.I have tried using VBScript and JavaScript to put a button in the html.As long as the function or sub I call is also in the same html document, it works, but I really need to transfer the control back into visual basic where I can do the heavy lifting I need to.can I just not do this as a regular VB application? Any way to do it without adding the complication of requiring ActiveX?
I have a webbrowser control, where I show images (bmp files, that the program creates), and I want to add some UserControls to setup the images (as showing layers, or choosing colors to display). Is easy to do appropiate UserControls on VB.NET, and I know almost nothing about HTML, so, I would like to add standard VB.NET UserControls near the images.
