your prorgram? How can be your program, if you actually have nothing? :)
Please, tell us a bit more what exactly do you want.
You know, we are here to help, not doing code instead of you guys.
So, if you will not out some effort, at least giving us a decent issue explanation, why would we then waste out free time for you?
Come on...
Btw, do you have any code done yet?

For registering user, you basicly need his username and password. Username must me unique, that means it can ONLY be one (it must not repeat - its meant like ID).
To answer on your questions:
1. To check is user already registered: you need an sql query to check if this username exists in database:
Private Sub MyMethod()
Dim IfUserExists As Boolean = CheckUserNameExistance(txtuname.Text)
'user exists!!
'notify by message about this user name already exists, and it must be changed
If IfUserExists Then
'user does not exist, so can continue
Else
End If
End Sub
Private Function CheckUserNameExistance(user As String) As Boolean
Dim bExisting As Boolean = False
Using conn As New SqlConnection("connString")
Dim query As String = "SELECT UserName FROM Users WHERE UserName = @param"
Using cmd As SqlCommand = New SqlComamnd(query, conn)
Dim obj As Object = DirectCast(cmd.ExecuteScalar(), String)
If obj IsNot Nothing Then
bExisting = True
End If
End Using
End Using
Return bExisting
End Function
- How to verify the password and reennter password?
QUESTION: What do you mean by verifying? To check its strenght? Or simply equality of both inserted strings?
