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?

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 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
[code].....

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 already found some site about it [URL]

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.

I am trying to pull some report details from a website. my home page is having a list of Report IDs, by clicking them i will be navigated to the detailed reports.. Similarly i have so many report IDs in my home page... i have loaded my page in webBrowser1 and capture the link of the first report id by looping through the page. After capturing the link of first report id i am trying to navigate to the link using webBrwoser2 which is placed in the same form. the page loaded sucessfully and i can extract the report to the textbox.
Here is the problem : before complete the navigation action in webbrowser2 the first loop used to get the links of report IDs got completed. So i am not able to loop all the report ID's Link to get all details.
I am not sure i am doing the right way of extracting a data from a web page..

I am utilizing a webbrowser control in vb.net 2005 to display excel workbooks
We are using this control to open excel documents. Webbrowser.ShowSaveAsDialog() allows the user to save the excel workbook open at any location he wants
However, I don't want the user to decide where to save. Is there any way to save an excel document from the webbrowser control without going through the ShowSaveAsDialog?
On closing of webbrowser, a simple prompt to user whether he/she would like to save changes should be fine enough
As of now, I can close webbrowser control and it does not prompt the user to save the changes. Actually, all changes are lost until and unless I perform a save (Ctrl+S) manually

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.

I'm looking for a .Net PDF Viewer tool that will accept the barcode font as well as allow the user to save, email, and print the PDF. I tried the tool by SkySof, but it doesn't handle barcodes. We're having trouble using the COM PDF control because of other stuff that needs to be installed on our servers. Our customer would prefer that the tool be under $1000. We're using Visual Studio 2008 and this is a windows application being served up by Citrix.
