On the login page I made, this is part of the code behind for the submit button.
Dim aCookie As New HttpCookie("userInfo")
aCookie.Values("user") = Me.usr.Text
aCookie.Values("last") = Now.ToString()
[Code]....
For some reason, when it gets to the last line, it throws an error:
Description: An unhandled exception occurred during the execution of the current web request. review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.
its possible to set the webbrowser cookies as same than httprequest cookies.

I have a program that adds controls on the fly to an auto-scroll panel. When the panel is scrolled (viewing the bottom of the panel for example) and a control is added, it looks like it is added assuming the top left corner of the panel is still at 0,0 when in fact it may be 0,500. To see what I am talking about, create an empty "Windows Forms Application" project and insert the below code into it.
Friend WithEvents Panel1 As System.Windows.Forms.Panel Friend WithEvents btnAdd As System.Windows.Forms.Button Dim ButtonCount As Integer
i have multiple forms in a project and all have statusbar. there is no way to add textbox on status bar but in my previous thread i got the help to add the text box. i created a function in module so that i call that function from all the forms on load and add the textbox on status bar and also add the event on textchange. the function to be called on event change is in individual form (at present)[code]
I have a datatable property called prpParametersTable in a class called clsBatch. I have a procedure that sets a datatable variable called dtP equal to prpParametersTable at the beginning of the procedure. I then add three new columns to dtP.Here is my problem. When I add the three new columns to dtP my original table prpParametersTable also gets those columns added to it, why? I only want to add the three columns to dtP and not prpParametersTable. How can I do that?
Private Function prvfnc_InsertBatchParameters(ByRef cnn As SqlConnection, ByRef trans As SqlTransaction) As String ' set new columns that have BatchID, Insert DateTime, and UserID for the SQLBulkCopy method below Dim clm As DataColumn Dim dtP As DataTable = clsBatch.prpParametersTable
I'm attempting to delete all cookies under a certain URL. How exactly would I go about completing that? For example, I want to delete all the cookies under [URL]. How would I do that?
I am using Visual Basic/Visual Studio 2011 Beta I have a series of web sites I program webbrowser1 to navigate to. It is a simple program. The problem I am having is that the websites remember me from the last visit from my cookies(?). Even if I have webbrowser1 click on the logout link, the next time I visit that site I am still logged in! I want the webbrowser to arrive at the website each time as if for the first time ever there, with no record of anything on that site that was done before.
I know HOW to use cookies, but how to do so in a Windows Forms Application? What reference would I need to add in order to add cookies to the user's machine?
I am using ASP.NET and C#. I must read a cookie called "TheCookie".TheCookie have about 3 values in them. Cookie1, Cookie2 and Cookie3.How would i get the value in code to read Cookie2's value inside "TheCookie"?
This is how i would read when a cookie only have 1 value, but i dont know what to do when there are multiple vales in the cookie Code for VB.NET
Dim userCookie As HttpCookie userCookie = Request.Cookies("UserEmail")
How I can check If a page have cookies or not? (I made a code to show they in a ListBox, but If the page don't have cookies, a runtime error appears (the second runtime error I ever had))
I use a webbrowser control in my VB.Net Program, and I want to delete all the cookies from the computer. How can I do that?And also how is it possible that I enter some site through my Internet Explorer, and it sets a cookie on my computer, and then I try to enter the same site through the webbrowser control in my program and it doesn't recognize that cookie? It uses the same browser, isn't it?
This question pertains to the use of the cookie-capable WebClient derived class presented in the How can I get the WebClient to use Cookies? I'd like to use a ListBox to...
1) display each cookie individually as "key=value" (the For Each loop displays all of them as one string), and
2) be able to display all cookies, regardless of the domain from which they came ("[URL]):
is there anyway that I could delete the cookies that my web browser stores when I visit a certain page. I don't want to delete all the cookies for internet explore, just the ones for my web browser
Im trying to get facebook enabled at my school, since its blocked. I found a way to get around the block by using a proxy but it wont let me sign in since cookies arnt enabled. I though of using VB to get around that. so far I have the proxy'd link as the web browsers url. But it still wont let me sign in.
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.
In the beginning, I set a cookie value like this:Response.Cookies("UserInfo")("UserName") = "Bob"nd it was good.In the end, I need to read that cookie in javascript. But I have no idea how to do that. The documentation for javascript and cookies (especially those set like I have above) is poor at best. Most cookie-reading functions out there seem to only accept 1 argument (cookie name). But as we clearly see here, I have to pass two arguments to get the value for "Bob".
I Want to have a WebBrowser1 and WebBrowser2 on the same form and be able to login to WebBrowser1 with account1 and login to WebBrowser2 with account2.
I'm having hard time to get a captcha to picturebox1 using picturebox1.load because it creates a new request or something I dunno and the captcha images is not the same as i see over webbrowser1. so what I want to be able to do is use the same webbrowser1 where i see the captcha and using this webbrowser to grab the captcha image using picturebox1.load or save it to hard drive and load it after, how can I do that? when i go to captcha SRC with the current webbrowser1 I see the correct captcha image but if there is another browser it will mess it up (Cookies?)how can I save or load the captcha with same webbrowser1 to keep the cookies so i can see correct captcha image?
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.
In all my previous vb programs I've used the webbrowser control to do things. I'm starting to use the httpwebrequest. So what I'm trying to do with the program is log in to [URL]..This may seem really easy but I'm having issues with the cookies. Once I'm logged in I can access any pages on the subdomain my.ign.com but the second I go out side to something else I'm logged out.
Is there something that I need to change in the cookie? Below is my code so far
I'm trying to check a few accounts on a website using web requests. It stores the authentication cookies and the problem is i can't get it to "logout" so to speak. It needs to logout by clearing the cookies since you can't exactly "navigate" to the logout URL.I got a bunch of code but this is the cookie bit:
Dim TempCookies As New CookieContainer Dim logincookie As CookieContainer and...
