VS 2008 : How To Clear WebBrowser's Cache/cookies

Jan 14, 2011

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)

VS 2008 - Clear IE Cookies Without Restart Program?

Jan 19, 2011

I use this to delete cookies
System.Diagnostics.Process.Start("rundll32.exe", "InetCpl.cpl,ClearMyTracksByProcess 2")
works fine I checked the folder myself it deletes all .txt files.

But here Is the problem lets say I log into hotmail, Clicked the button to Clear my cookies. And navigate to log in page again, It will navigate me straight to inbox just as if I have cookies but the folder doesn't have .txt cookies file. just (index.dat). Is this means we must restart the program to this to take effect? (Works if you restart it) If so, how can I turn off webbrowser1 for a sec and turn it back? or something like that just to make sure it takes effect without me reopening the program.

VS 2008 - Deleting Cache While Using Webbrowser

Oct 21, 2009

I'm writing a program that uses a webbrowser to update a page and gather its data. But it's reloading the page from the cache. I located the cache and quickly found that it cannot be deleted like normal files.

Now i really only need to delete one file, specifically a javascript file, because that's the only thing i need updated. But deleting the cache is proving to be a bigger problem than i thought, let alone deleting a single item from the cache.

VS 2008 Webbrowser Control And Deleting Cookies?

Jun 3, 2009

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.

VS 2010 : Clear All IE Cookies?

Feb 7, 2011

I'm working on an email application atm, and a main feature of it is that it allows someone to enter multiple email accounts and all of the emails will be aggregated on the one form. It would be quite easy to log out of each account if I could delete the cookies. I've tried looking in the "RoamingMicrosotWindowsCookies" folder, but there are no files at all in there, so I have no idea where the cookies would be going.

So, my question is, does someone have a function written that will delete all of the IE cookies currently in place? I can already clear the cache, but I really need to figure out how to delete the cookies.

Clear The Cookies For All Domains Once User Logs Out?

Mar 23, 2011

The code below tries to clear the cookies for all domains once a user logs out of the system. For some reason, only the last domain in the array is cleared. Why does this happen?

For example, if I change the size of the array to 4 and then change the for loop to only go to 3, then it only logs me out of y.xcv.com.

As a sidenote, I have this loop working on a different server that uses a slightly different function to clear the cookies.

Edit: Code updated per suggestions below. Now it fails on the "as HttpCookie" line. Do I need to include some library?

Dim aDomain(12)
Dim ESidCookie, WIdCookie, EBidCookie, TSidAccessCookie, PSidAccessCookie, SSidCookie As HttpCookie

VB Clear Or Delete Browser Cookies, History And Temporary Files?

Aug 13, 2009

what a good code to delete my "Webbrowser1" cookies (not my IE7 cookies !) I would also like this program to delete the Webbrowser1 History & Temporary Files as well, but mainly the cookies. I would like for this program to either delete cookies by a simple click of a button or to set a timer that can erase the cookies every few minutes. Also, if it could show the current cookies before being deleted.

Webbrowser Control And Cookies?

Mar 27, 2010

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.

Delete Cookies From Webbrowser Control?

Apr 1, 2010

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

HttpWebRequest, WebBrowser, And Cookies (VB2010)?

Aug 26, 2011

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

Save / Read Cookies - WebBrowser Tool (GUI)

Sep 11, 2010

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?
