View 1 RepliesI have been trying to use the WebBrowser control to access a website, nothing fancy involved, just a Security Certificate error message I can't get around:
The site that I've been trying to access is [URL].. By clicking on the "Login" hyperlink you are taken to a https connection.Internet Explorer simply allows you to click on the "Continue to this website (not recommended)" link which displays the Logon screen.Clicking on the same link in a WebBrowser control simply reloads the page as (I assume) WebBrowser has not been told that the page is ok.
I've tried looking around for the solution with no luck, it seems like such a simple problem..
I'm trying to access a secured website using vb 2005 and webbrowser control. I've got the credentials, the script can pass the login page but when trying to navigate to the second page within, the page is being redirected back(to the first page after logging in). The second page I'm trying to get to retrieves the data from a database and displays some options for the user to select in order to prepare a report which can be downloaded after the fields selections. And I wanted my script to do this automatically without user interaction.

Dim userID As String = Session("UserID")
This is just a page in asp.net. I want to be able to grab the Session("UserID") but every time I try, I get this error:
Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. Please also make sure that System.Web.SessionStateModule or a custom session state module is included in the \ section in the application configuration.
If I put that Dim userID inside say the Page_Load Event, then it works fine. Why does it have to be inside an event? I want to dim it once, and use it throughout the page.

I programmed my website using visual basic code (via microsoft expression web) and need to post information to a remote location using a php page. How do I take variables from my visual basic code and transfer them to my php code? I was thinking sessions would work, but I haven't figured it out yet.
View 7 RepliesMy vb.net application needs to use a session variable. I don't really know how to use it in ASP.net. I've been trying to use what my books have, but I can't get this label to work. I need the user input to be validated against the database and if their code is in the database, the textbox should disappear and a label will appear saying Welcome. The way I wrote it, I get an error saying the server tag is not well formed and in the codebehind it says that the ID of my label is not declared. Can anyone spot any problems with the code I wrote?

I am using ASP.NET. It is possible to create a session variable on page load just for a particular page/url? The problem that I have is: The user comes to page 1 and the session variable becomes A, then he opens page 2 in a new tab and the session variable because B on both page 1 and page 2. So when the user needs the session variable on page 1 it does not work because the variable have changed!

I'm using a compiled .dll provided by someone else -- I know little about it, other than it has a session variable that I must access in a way that is strange to me. Not sure what to call it -- have googled for words that I thought might be right, but so far no success.
View 2 RepliesHere is the situation: User logs in via username/password stored in an MSSQL database If the user is authenticated, the system makes a session variable with username/SHA1'd password and boolean if the user is logged in or not (for subsequent pages) I need to be able to destroy the session variable. I want a confirmation box as well.
This is what I have so far:
<script type="text/javascript">
//<![CDATA[
function doLogout() {
[CODE]...
Since it is an ajax request won't reload the page (the functionality works fine, the request destroys the session), I think I need a different approach to do this. I would really like to be able to do it all in ASP.NET if possible.
Does session variable shared accross different browser? If not is there away that I can share information accross browser similar to the functionality of caching but the scope is wider.
View 3 RepliesI keep a Session variable when the user is logged in. So that when the user click on btnLogout it must clear all my sessions and Log the User out for GOOD!!!
It does clear my sessions but if i click the BACK button in IE right after i logged out then i am still logged in! Meaning it goes back to screen where the user was still logged into.
My code on log out
protected void btnLogout_Click
{
Session.Clear();
Session.Abandon();

Is there maybe an option in code i can do that will disable the user from pressing the BACK button in the Web Browzer?
Im trying to grasp session varibles, i understand what they are etc but i would like to know how to define a type for each session variable.Iv written it like this
Session("Title") = txtTitleContent.Text
How can i tell it what type of value is going to be in it, because at the moment im only playing about with strings, but what if i have an integer and want to pass it back to the back end to save it will throw an error saying "conversion from string to integer is not valid" should i use Cint to deal with this?
As the title states, I have a session variable that is set during a login script with asp.net and vb.net code-behind. Can I call a javascript function when a link is clicked that will destroy that session variable? If it is possible, can I use jQuery to make that process easier?

I'm using some session variables to store and pass data across several pages of an ASP.Net application. The behavior is a bit unpredictable though. [Code] Ok so far so good, on a normal page load. If the user completes the form action, hits the next page, and decides OH NO, i needed to change field xyz, and clicks back, corrects the data, then submits, the session variable is showing as NULL. Why would a cached session behave this way? I'm not destroying/clearing the variable, unless I fail to understand the scope of session variables.
View 1 RepliesI have a session variable in my asp.net application. The session variable holds a value from the database, that reflects a customized HTML color value.In my application, I have an asp button with server side code
btnContinue.BackColor = System.Drawing.Color.FromName(Session("ContinueColor"))
Issue: However, when I run the application, the color value is not being reflected in the button. I did double check, and the session variable does hold the correct value.There are other objects, that use session variables to display colors, and they are working fine.
Update: When I force a color "btnContinue.BackColor = Drawing.Color.Blue", that works perfectly fine.
I have 2 web pages.

Currently, in my web application I have a listbox that gets populated client side (via java script) with a set of ids -- we'll call this page 1. Server side, I am populating a variable with the ids and passing it through a query string to another page -- we'll call it page 2. Now, I have a previous button on page2 which allows me to go to page 1. I'm trying to figure out how to repopulate the listbox on page 1 with the values previously selected. I was thinking of just storing the set of ids in a session variable and using it client side to repopulate the list box. Can anyone advise on how to access a session variable client side?[code]...

I have an asp.net website to manage projects. I realized that when I click for the next project really fast and often it overrides all the next projects with the data of the first one. I call a method to save before to go for the next project. I use also a session variable for the id of the project.
EDIT: It looks like the sever stacks the save method and the ids but keeps the values of the first project in the controls this is the ajax that calls a server method to get the id and set it in an hidden field:
