Validate The Given Password Is Same As The Current Users PAssword?
Mar 21, 2011
I have developed a task Using VB.net (windows Application). I want to create a Login window for the Current user only allowed to use my application.So In my Login window UserNAme textbox I have showed the curent Login UserNAme like,
txtUserName.Text=Environment.UserDomainName & "" & Environment.UserName
And I have set txtUserName.Readonly =True.
Now the User to type the Password in my application password textbox.
I am implementing a system where the user can Reset their password if they have forgotten it.Once it is reset I want to give them the option of changing the password so that it will be something more memorable to them.The password is hashed and if i enter in the correct old password and new password the password does change.If I enter in the wrong old password and new password the password doesnt change.Is there a way to match the old password with the old password field in code behind so I can throw up an error to the user to tell them what is wrong?

I had one user in my db and when using this code it validates my username and password, but when I added a second user, it does not validate the second user, only the first one. I removed the first user and added it to my db after the new user, but it did the same. What can I do to make sure it actually runs through rows in the db and compare the information in the text box with the information in the database?
Dim sqlStatments As New SqlClient.SqlCommand( _ "SELECT * FROM Users", UCSMISDB)
I am working on a registration form and it requires to put in password that's atleast 6 characters long but shouldn't be more than 15. And contains atleast one number.
How do I write code to check if the user have met the requirements or not?
Long story short I have a situation where some users have access to two domains that do not trust each other. They log into one domain and their user ID's are identical on the other domain. So when they change their password on the first domain they need to call into tech support to have it reset on the second domain. I'm writing a app that checks if they have access to the first domain but not the second and if this is found to be true it prompts them for the new password to update the second domain.
Here is where I am stuck. The following code works GREAT but I need it to be more flexible:
Code:
Friend Function ResetPassword(ByVal OldPassword As String, ByVal NewPassword As String, ByVal UserName As String) As String ' Resets a users domain password
[Code]....
The issue is the CN is different between domains (one is first name last, other is last name first) so I need to search by UserID which is the same between the two. So I tried searching by sAMAccountName but it says object not found. Also I need to be able to search the entire Super Corp OU. When I get rid of the extra OU's the search also fails
So I need to search LDAP for sAMAccountName anywhere in OU=Super Corp. How can I do this? Every combination I try seems to fail yet if I hard code it like the above example it works great. The idea is to replace CN=John Q. Public with sAMAccountName=" & username & " to pull jsut that user on the fly.
If it matters all clients are XP SP2 or higher, both domains are Server 2003 or higher. VB 2008 SP1. The error message when a different search is done is a "Object not found".
When I originally set up my project I 'hard-coded' my username and password in so that I could access a remote DB2 database. Now that I need to publish it to other users they need to be prompted for their own usernames and passwords. I've gone to "My Project/Settings" and deleted the items from the string - but when I run I get the following message on the statement:
I am using the Mysql .NET connect and can connect to my database using my program. i want to be able to get a Users Password from the database using there user name
This is the query i want to use: "SELECT Password FROM staff WHERE Username = " & textbox1.text & " '". But i don't know how to run that query and to get it to store the Password as a variable

I'm trying to create a password change form for my company's vendors. There are a couple of scenarios I could encounter doing this:
1 - User enters invalid current password 2 - New passwords do not match 3 - User's account is locked 4 - User cannot authenticate because password is expired
It's case 4 that I'm struggling with, because their is no way for me to take the password the user entered and verify it against active directory without getting an error.
How do you get a textbox being using for password entry to display the black circle that you often see in web forms, on the iphone etc etc?
I can change the PasswordChar property to an asterisk no problem and even copying and pasting symbols inserted into Word seemed to work - just couldn't find a symbol that looked like a bullet point!
Can this actually be achieved for a standalone exe, or is it something unique to web forms? Surely copying and pasting symbols from Word isn't actually the answer?

How do I force users to save the current record (if current record has changed) and not let user go to the next record unless the save button is pressed?
VB.NET Private Sub MaximizeCare() For Each p As Process In Process.GetProcessesByName("clinical_carestation") ShowWindow(p.MainWindowHandle, SHOW_WINDOW.SW_MAXIMIZE)
[code]....
But the trouble is that if multiple users are using the same terminal I cannot narrow down the process list to just the current user. So if two users run the same application simultaniously only the first user can open the application on the same terminal.
