Login Screen Code

Using an unbound table "Account Table"consiting of "ID" AutoNumber column "Username" Column and "Password" column. the form.loginscree n retrieves data from the table.Account Table.

the form consists of 1 combobox bound to the username column on account table and 1 unbound textbox named Password used for password input. also on the form is a command button titled exit database and 1 command button titled login.

Obviously the Login Button with command on_click is bound to an event in the below code initiating the process to verify the username to the password located in the Account Table. which works right now just fine with one exception

when initially getting the loginscreen, i get to select my username, however, when i type in the username it is overwriting the other fields in the account table. however if the username has is in the drop down and unique by means in which it has not been over written then the username and password works fine and continues to the switchboard. otherwise 'Else happens.

Code:

Option Compare Database

Private Sub Combo11_AfterUpdate()
'After selecting user name set focus to password field
    Forms!LoginScreen!Password.SetFocus
End Sub

Private Sub Command5_Click()
'Check to see if data is entered into the UserName combo box

    If IsNull(Forms!LoginScreen!Combo11) Or Forms!LoginScreen!Combo11 = "" Then
      MsgBox "You must enter a User Name.", vbOKOnly, "Required Data"
        Forms!LoginScreen!Combo11.SetFocus
        Exit Sub
    End If

    'Check to see if data is entered into the password box

    If IsNull(Forms!LoginScreen!Password) Or Forms!LoginScreen!Password = "" Then
      MsgBox "You must enter a Password.", vbOKOnly, "Required Data"
        Forms!LoginScreen!Password.SetFocus
        Exit Sub
    End If

    'Check value of password in AccountTable to see if this
    'matches value chosen in combo box

    If Forms!LoginScreen!Password.Value = DLookup("Password", "AccountTable", "[UserName]= '" & Forms!LoginScreen!Combo11.Value & "'") Then

        'Close logon form and open Switchboard

        DoCmd.Close acForm, "LoginScreen", acSaveNo
        DoCmd.OpenForm "Switchboard"

    Else
      MsgBox "Password Invalid. Please Try Again", vbOKOnly, _
            "Invalid Entry!"
        Forms!LoginScreen!Password.SetFocus
    End If

    'If User Enters incorrect password 3 times database will shutdown

    intLogonAttempts = intLogonAttempts + 1
    If intLogonAttempts > 3 Then
      MsgBox "You do not have access to this database.Please contact admin.", _
               vbCritical, "Restricted Access!"
        Application.Quit
    End If

This is the code for the Switchboard however line 319 below is where once the password has been verified it opens the switchboard causing on Load the form closes the Splash Screen preventing further looping of the loginscreen. if the loginscreen is attempted to be bypassed then it continues to cycle and loop until closed by the switchboard being loaded. so this is where i want to enable only the authorized forms or buttons based on security level. should i add a security level table and link to the username in the account table, and code the switchboard buttons so they are available to only those specified users, or would it be best to get rid of the switchboard and have user based forms with their allowed buttons.

the office only consists of approx. 15 soldiers, however this might be ok if it would be the same 15 forever, but simply not the case the soldiers depart after 1 year of assignment to korea. so each user having individual form i cant see feasable, unless maybe a general user form for certain departments and assigning a permission level to each of the department forms. that may be an idea.

let me know what yall think, i am in the wind right now, and i know there must be something i am overlooking for a solution to my dilema. thanks for any and all help.

too much code and too many questions to truly post. lol, you really have to see the database in its current state to understand what i am going for.
