VS 2005 Validation On A Password
Aug 1, 2010
I am new using VB2005 and I need some assistance with the following:I have a created a program that connects to a Access database, the user has to have a user name and password to be able to access the application. So far that is working correctly it validates to make sure that the user and password does exist in the logon table.As you know sometimes people forget their passoword and the administrator has to reset it. I have setup a default password when ask to be reset it which is "Support".If someone logs in using their logon and the temporary passoword (Support) the system is going to promt the user to change it.I would like for the validation of the temporary password not for just anyone to use someone elses logon and just type "Support" and promt them to change it. how can i make sure that the password has been reset.[code]

I have a form just like the login form in VB.Net. The usernames are prepopulated on a combobox with datas from the SQL DB backend, and the text box for the password entry is empty. My code is working but what I need help is, for the code to validate the username and password entered against that stored on the SQL DB backend. Like when the user selectes a wrong username but the password entered is correct, there shld be a messagebox like "The username selected is wrong", or if the username is correct and the password entered is wrong then the msg is "The password entered is not correct, please type you password using the right case".
Try
conn.Open()
Dim SelectStm As String = "SELECT * FROM tblStaff WHERE UserName = @UserName AND Password = @Password"
Dim objCmd As SqlCommand = New SqlCommand(SelectStm, conn)

I'm creating an application using VB.Net. I have a loggin form which has a username and a password textboxes. I have the following code which is working, which I believe is actually validating the username and password. My hicccup now that Else statement. How do I write the codes for the If......Else part, like if the username is correct and the password is wrong then the msg should be "The Password is incorrect" or vise versa, or if both are incorrect then it should also generate a message.
Try
conn.Open()
Dim SelectStm As String = "SELECT * FROM tblStaff WHERE UserName = @UserName AND Password =

The lbl text should show "Incorrect Username/Password" if the Username and Password do not match.
Code:
Protected Sub btnLogin_Click(sender As Object, e As System.EventArgs) Handles btnLogin.Click
Dim conn As New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:UsersBrianDocumentsVisual Studio 2010WebSitesPetLandiaApp_Datadb.mdb")

I'm using the ASP.NET Membership provider and using the Password Recovery control to reset the user password if they forget it. On the whole it all works fine, but with one catch when it comes to validation.I have expanded the PasswordRecovery control out to use the template feature to customise the appearance, which is all fine. I have set the user lookup error handler using:
OnUserLookupError="PasswordRecovery1_UserLookupError"
in the opening tag and if I load up the page, type in some junk name and click submit this fires as expected, in all browsers. The snippet of VB code makes an error div visible and sets some text.However, if upon loading the page for the first time I type a duff name into the username box and hit the enter key to submit the form, in Internet Explorer (version 8), the UserLookupError event fails to trigger. It triggers just fine in Chrome or Firefox, just not in IE. I know it's not a focus issue on the form, as I can see the form is being submitted.If I click the submit button first, then following that hit the enter key it does fire, it's just that first time it doesn't, and only in IE.Also to add that if I set breakpoints in the VB code to check to see if the page is being submitted, I can see the Page_Load event fire when I hit the enter key, but not the sub PasswordRecovery1_UserLookupError.

For fun I decided to make a password changer tool. The app pulls the local admin account from the registry so I can change it. This is nice because I don't have to select the account from the list, it just pulls it from the registry. So Here is my issues. I want to be able to have the code verify the password meets complexity requirements before it is changed. For example I don't want to be able to put any old password in like "password". I have searched and searched but to no avail. I am not asking for someone to write the code fro me

I have a piece of business-soft to make the lives of our employees easier. It's fairly typical, a tabbed-MDI style main form with a load of buttons that activate each of its sub-modules.
I have security set up on it so that someone in sales can't enter the module for purchasing, etc... I authenticate the user by having them type in their network password and check it against the AD server with this function:
'Remember to Imports System.DirectoryServices for this to work
Private Function ValidateActiveDirectoryLogin(ByVal Domain As String, ByVal Username As String, ByVal Password As String) As Boolean

Design a form, which contain a TEXTBOX control that accept a UserID input, with a CommandButton control to perform a validation based on the criteria listed below. Display a Message on whether the UserID is Valid.
Criteria:
The UserID must contains SIX digits follow by a single character, limit the entry to a maximum of seven characters only.
The postfix character of the UserID is derived from the summation of all the six digits divided by seven and using the remain as followed:
Remain
Character

I am trying to figure out a way to implement password protection on documents that a program I am working on creates. They should remain with the document regardless of where it is copied to or sent.Here is a rough sequence of events:
1. Application Opens (no document loaded).
2. User opens document with extension registered to application.(could also be # 1 if they clicked on the document directly)
3. Application Security checks document for security and prompts if necessary.
4. If prompted, user enters password.
5. Application checks password.
6. If passed, document opens, otherwise user is notified of failure.

Does anyone know how to store the connection string in a file rather than hard coding it in the application. For example i have declared this connection string in the form to connect to oracle database and it works. But i assume this is not the right way to go by if one is looking for more secured environment.
strcon = "Provider=MSDASQL;" & _
"Driver={Microsoft ODBC for Oracle}; " & _
"CONNECTSTRING=(DESCRIPTION=" & _

i have a login form in a banking project.i set a userid and password for this login form and i did the code accordingly,it works good.In my form there are two fields namely:Userid and Password and a button named Login.
But i cant get any idea about what to do when the user wants to create their own userid and password?
I think i need to add a few more buttons to enable the user to create their own userid and password but i cant get the idea......i need some help.
Again,if i allow the user to create their own userid and password then anyone can use my project by creating a new account.........
Hence i am totally confused how to go with this.I need some urgent discussion so that i can get through this problem.
