"I love VB.NET"! It lets me do things that I should not and does not throw errors. Then after working for months it will blow up never to work again! So I like to use C# as it does not let me get away with "anything"! :)

Anyway, here is one example I use as a data class.

I have the feeling that this line may not be in your code:

cmd.ExecuteNonQuery()

If you still have a problem please post your code.

VB NET Update

Public Shared Function UpdateUser(ByVal userID As String, ByVal PhoneExt As String, ByVal FirstName As String, ByVal LastName As String, ByVal DepartmentCode As String, ByVal PositionName As String) As SqlCommand
        ' Update User Record...
        Dim sql As String = "UPDATE UserInfo SET PhoneExt=@PhoneExt, FirstName=@FirstName, LastName=@LastName,DepartmentCode=@DepartmentCode, PositionName=@PositionName WHERE userID=@userID"
        Dim UpdateUserConnection As SqlConnection = GetConnection()
        UpdateUserConnection.Open()
        Dim cmd As New SqlCommand(sql, UpdateUserConnection)

        cmd.Parameters.Add("@UserID", userID)
        cmd.Parameters.Add("@PhoneExt", PhoneExt)
        cmd.Parameters.Add("@FirstName", FirstName)
        cmd.Parameters.Add("@LastName", LastName)
        cmd.Parameters.Add("@DepartmentCode", DepartmentCode)
        cmd.Parameters.Add("@PositionName", PositionName)

        If UpdateUserConnection.State = ConnectionState.Closed Then UpdateUserConnection.Open()

        cmd.ExecuteNonQuery()

        UpdateUserConnection.Close()

End Function
