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 am tried to develpod login page for System staff Library.I want to modified my login page which only allow user which has register in the system able to access.If the user want to login but dont have any username and password yet user will got message error.

I am raw to this and have been plodding along slowly to get a little windows application working. I am having some issues when testing my application. I've included the sample code that I am using:

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 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?
How do I assign a My.Settings.Item connection string to cmd.Connection connection string value?

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 got this Error Message while I try to preview the records in Dataset Designer:"The connection string could not be found or Data provider associated with the connection string could not be loaded"
I understand the possibilities for encrypting a connection string in .net v4. I have a win forms application that will be used by multiple people on different machines. I understand that I need to protect the connection string at time of the app being first run on the target machine. However I am concerned that for a period of time my connection string will be unencrypted. I am looking for advice in how to deploy my app with the connection string already encrypted or encrypted during installation. encrypting the connection string in a secure way?
I'm developing an app in vb.net (visual studio 2008). I have a Teradata back-end that will be supporting multiple users in a production environment. I need to use variables in the connection string as the user/pass will be changed every 3 months.
For the gist of the application:
In it's most basic form - I have a search form which works correctly - it pulls results into a listbox and the user then double clicks the list box which will then open a form that is bound via table adapter to the back-end table (Teradata). My connection string is fine everywhere in the application. My problem is using a modified connection string for the "fill" function of the table adapter once the form is opened.
I'm using the code below for the on-load event and keep getting an "invalid connection string" - again, the connection string works fine everywhere else in the app, and the variables etc... are working correctly.
Private Sub adaptertest_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Dim DBConnStr As String = "Provider=TDOLEDB;Data Source=TDDEV;Persist Security

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.
