Créer un formulaire login à l'ouverture d'une base de données

je vennais de créer la table des Utilisateurs et formulaire Logon, maintenant je ne sais où introduire la commande SQL


SELECT [tblEmployees].[lngEmpID], [tblEmployees].[strEmpName]
FROM tblEmployees;

C'est dans quelle Contrôle ? et quelle est la procédure

Pour le code:

Private Sub cboEmployee_AfterUpdate()
'After selecting user name set focus to password field
Me.txtPassword.SetFocus
End Sub

et

pour le code:

Private Sub cmdLogin_Click()

'Check to see if data is entered into the UserName combo box

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

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

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

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

If Me.txtPassword.Value = DLookup("strEmpPassword", "tblEmployees", _
"[lngEmpID]=" & Me.cboEmployee.Value) Then

lngMyEmpID = Me.cboEmployee.Value

'Close logon form and open splash screen

DoCmd.Close acForm, "frmLogon", acSaveNo
DoCmd.OpenForm "frmSplash_Screen"

Else
MsgBox "Password Invalid. Please Try Again", vbOKOnly, _
"Invalid Entry!"
Me.txtPassword.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

End Sub
