I have a login page where I display all the sql servers available and when the user selects the server, all the databases are displayed in a different combo box. Then the user enters the userid/pwd and clicks logon button.Assume that the credentials are correct and sucessfully established.
Now what I want is to store that connection string into somewhere so that all the different operations can be carried out without referring to the config file.One option that I have is to declare a public variable in DAO class and assign the connection string to it.Is there any other better way to handle this situation.

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?

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 believe this is referring to the connection string. I've set breakpoints and checked that the entry in the password is correct (and that there is a value in it).

I created a SQL DB named MainDB.mdf and a small VB 2010 application with some forms and datasets.Everything was working OK until i got a new computer and re-installed Visual Studio 2010 and SQL server 2010 on it. I copied my DB from the old to the new computer and also copied by VB 2010 project to it. I used Windows Authentication to connect to the DB in the old computer and also in the new one, i am using different Windows user account names though.
I was able to connect to the DB in the new computer in the Server Explorer section, i created a new connection string to the DB and i can seed there is data in the tables. When i run my VB 2010 application created in the old computer get error:
"Cannot open database "MainDB" requested by the login. The login failed. Login failed for user 'D630Admin'."
I need to get rid of that error and be able to add/mod/del data from my DB using my VB application as i used to.

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.
