I have a site where users must only be able to access the Login.aspx page via SSL/HTTPS.Currently I run something like the following in my Page_Load():
If Not (IsSSL) Then
Response.Redirect("https://" + thisDomainName + "/Login.aspx")
End If
Is there a better way of doing this?

I had a problem with WebBrowser component. Basically, it works improperly when try to log in on one web-site (Forex Trading Social Network | Online Forex Trading Forum and Social Networking Site). I am working with Visual Studio 2010 Professional. I created a simple WebBrowser trying to access the indicated web-site. The problem begins. Well, the website loads, but when you go to the login page (Forex Trading Social Network | Online Forex Trading Forum and Social Networking Site) and try to log in, it doesn't work. I mean, when I enter the login details the login page just refreshes itself and the login wasn't proceed. The same login page appear with every login attempt. The is the current problem!I check with Google, it works. But, it doesn't work with Forex Trading Social Network | Online Forex Trading Forum and Social Networking Site! Why?

I'm trying to make a project about a basic login system using visual studio 2008.I have a project that has 2 windows forms applications embedded in project.Form1.vb contains this:Code for Create account button:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
'we verify if the accounts folder exists
If My.Computer.FileSystem.DirectoryExists("C:\Accounts") = True Then

It is simply a "Y" in the road. If they are Company A, then I want to send the username and password over to that website and log them in as if they typed it in there. If they are Company B, then the same thing but with a different website. I do not know the term for this, so the google results are not very pretty.I can not do this with a query string (not that I'd want to anyway) as I do not want the username/pw to be visible.Here is the other weird thing. This can be done via a simple HTML <FORM> and Submit button as I have tested it. But I want to do it all in VB.NET code. How is it that it is possible with some simple HTML but not possible in VB.NET? I guess it could be a security thing, right? What do the good guys like us do when we legitimately just want our employees to go to one login page, enter their username/pw, and then (based on their username) send them to either pageA.aspx or PageB.aspx which receives their username/pw that they only entered once before on the first page?

So i've been working on a page for a project where the person logs into a login page and then can see a list from the database of employees. everything is working except for one problem. If someone puts in a username and password, username= a and password=b, for example it still allows that individual to view the next page and doesn't throw the error that i have enbedded on the login page to say sorry you have the incorrect password/username. The working code that i have so far is below:

I'm building an application in VS2008 (VB) and SQL 2005. I'm using databindings to bind controls to LINQtoSQL objects. If I bind a 'third level' property that can be null I get "Value cannot be null. Parameter name: component" error while disposing the control.
Steps to reproduce (8):
1- create TEST database in SQL
2- create tables like this:
USE [TEST]
GO
/****** Object: Table [dbo].[Table03] Script Date: 06/04/2010 12:26:44 ******/
SET ANSI_NULLS ON

second question:the apps developed with VB 2003 (these work with access too ..."jet oledb"). How I can compile as x86? I have not seen this option like VB2008.

I want to access a page variable from a user control placed on that page. All the solutions work in C# via casting to the page class. The problem is that this doesn't work in VB. The page class is not selectable from the Intellisense dialog. Manual typing results in the error type not defined. It is strange that C# can do this without a problem. What is the proper solution for this in VB? I had other cases where I needed to access a control on the main page. C# again uses a cast to the page class to access the control. This doesn't work in VB again. So how can I access the page class from a user control in generell?

Right now, I have this code:
string strURL = "aLogin.aspx?test=hello";
string strPattern = "(.*/)?Login.aspx(?.*)?";
bool bIsLoginPage = System.Text.RegularExpressions.Regex.IsMatch(strURL , strPattern, System.Text.RegularExpressions.RegexOptions.IgnoreCase);
I'm searching for the proper regexp pattern, and I am at a loss.The pattern must fulfill these criteria
Login.aspx ==> True
lOgIn.AsPx ==> True
/Login.aspx ==> True

I created a website in VWDE 2010, and I was trying to code the login page that gets automatically created with a new web site in vb. owever, the vb file doesnt recognize some of the items on the aspx page, for instance: the username textbox is called "username". in the vb file, when I wrote username.text etc etc, and then I debugged it, it gave me error " 'username' is not declared. It may be inaccessible due to its protection level. Why is it doing that? It's under a Protected Sub, but why should tht interfere?

I am using a Login page so the user can access the form. The thing is, I have a stored procedure that can get the user id and password, but I am not sure how to use it in VB. I know how to do it in ADO.Net, but I'm not sure if this would be similar. I want to make sure that a person doesn't use an SQL injection attack. Oh, and I am using SQL Server 2008, not Access. Here is my current code:

I have an ASP.Net 3.5 in VB.Net page that uses a master-page and has several pages it uses to display content. On the master-page their is a search text-box for the site so that shows up on all the pages. Their is also a login page screen to get to a members account.The issue is: When you are on a content page I would like when a user puts something in to search for and presses enter it will process the search request.But....If you are on the login page I would like to disable enter key for the search and if the user presses enter on the login page to process the login request.

I am kinda' restricting the user not to see the forum page in the current site (http://thisSite.com/forum.aspx), if the user is not logged in.I am not sure how to redirect the user back from the login page [url] back to the [url]
i tried placing response.redirect in my forum.aspx like this: response.redirect("https://somethirdpartysite.com"), but it's not behaving as expected.

I would like to create a secure login page for a pre-defined set of users (so no creating username/passwords by the users themselves). I've looked up a few sites and they all seem to suggest using Microsoft's Membership or something. I am not very sure as to why that's used, but all you need to know is that I will be creating the login details. I just need to make the login secure, ie, no duplicate logins, no logins from different browsers and cookies and sessions and encryption and all that. Any one have the code/links to where I can get all this?
