password, 3 times etc

How would I edit this so if a password was entered wrong three times it'll exit the program?

Thanks for any help.

VB Code:

Private Sub cmdLogin_Click()
    Dim PassRS As Recordset
    Set PassRS = Db.OpenRecordset("Login")
    While Not PassRS.EOF And Not LoginOK
        If (PassRS.Fields("password").Value = txtPassword.Text) And (PassRS.Fields("Username").Value = cboLogin.Text) Then
            LoginOK = True
            CurrentUser = PassRS("Username").Value
        Else
            PassRS.MoveNext
        End If
    Wend
 
    If LoginOK Then
        Beep
        frmIntro.Show
        frmPassword.Hide
        txtPassword = ""
        LoginOK = False
    Else
        Response = MsgBox("Incorrect password", vbRetryCancel + vbCritical, "Access Denied")
        If Response = vbRetry Then
            txtPassword.SetFocus
            txtPassword.SelStart = 0
            txtPassword.SelLength = Len(txtPassword.Text)
        End If
    End If
End Sub

add an integer variable to be a counter

Code:

---

Private Sub cmdLogin_Click()
    Dim Count As Integer <----------
    Dim PassRS As Recordset
    Count = 0 <------Initialize it to 0
    Set PassRS = Db.OpenRecordset("Login")
    While Not PassRS.EOF And Not LoginOK
        If (PassRS.Fields("password").Value = txtPassword.Text) And (PassRS.Fields("Username").Value = cboLogin.Text) Then
            LoginOK = True
            CurrentUser = PassRS("Username").Value
        Else
            PassRS.MoveNext
        End If
    Wend

    If LoginOK Then
        Beep
        frmIntro.Show
        frmPassword.Hide
        txtPassword = ""
        LoginOK = False
    Else
        Response = MsgBox("Incorrect password", vbRetryCancel + vbCritical, "Access Denied")
        If Response = vbRetry Then
            txtPassword.SetFocus
            txtPassword.SelStart = 0
            txtPassword.SelLength = Len(txtPassword.Text)
            Count = Count + 1 <---------Add 1 to Counter
            If(Counter > 3) Then <--------When Counter exceeds 3 show Msgbox
              MsgBox "3 Invalid Login Attempts...This program will now Close"
              End
            End If
        End If
    End If
End Sub

Cheers Memnoch :)

Hm, weird count isn't going past 1, any ideas?

Change

Dim Count As Integer

to

Static Count As Integer

Um, in his code he has:

VB Code:

Count = Count + 1
If(Counter > 3) Then
Msgbox

I think if you changed Counter to Count, it should work. This, of course, what you'd run into if you copied Memnoch1207's code.

Oh, and you don't need to change to the static part, either.

Destined

...because when you declare a variable using "Dim" the lifetime of the variable keeps its value only as long as the procedure is running. Once the function exits the memory used by the variable is zeroed out and you have nothing.

Using "Static" will keep make sure the variable holds its data.

Yea, sorry forgot to say I changed that part destined soul.. still stickin to 1 though
<edit> changed dim to static too, odd it should work.. </edit>

Ah, i didn't bother readin the rest of the code. Yes, it should be static, or else count will be set to 0 everytime they click the button. As well, you'll probably want to add count = 0 for when the login is done correctly (reset it so they can log in later...)

Destined

VB Code:

Count[b]er[/b] = Count[b]er[/b] + 1 <---------Add 1 to Counter
If(Counter [COLOR=deeppink]=[/COLOR] 3) Then 'Change this to =
   MsgBox "3 Invalid Login Attempts...This program will now Close"
   End
End If

Here's the code but updated..

VB Code:

Private Sub cmdLogin_Click()
    Dim PassRS As Recordset
Static PassCount As Integer
    'Initialize count to 0
    PassCount = 0
    Set PassRS = Db.OpenRecordset("Login")
    While Not PassRS.EOF And Not LoginOK
        If (PassRS.Fields("password").Value = txtPassword.Text) And (PassRS.Fields("Username").Value = cboLogin.Text) Then
            LoginOK = True
            CurrentUser = PassRS("Username").Value
        Else
            PassRS.MoveNext
        End If
    Wend
 
    If LoginOK Then
        Beep
        frmIntro.Show
        frmPassword.Hide
        txtPassword = ""
        LoginOK = False
        mdiMain.lblLoginTime.Caption = Format$(Now, "H:MM AMPM")
        mdiMain.lblUsername.Caption = CurrentUser
        mdiMain.timDisplay.Enabled = True
        mdiMain.mnuLogoff.Caption = "Log off " & CurrentUser
    Else
        Response = MsgBox("Incorrect password", vbRetryCancel + vbCritical, "Access Denied")
        PassCount = PassCount + 1
        MsgBox PassCount
        If Response = vbRetry Then
            txtPassword.SetFocus
            txtPassword.SelStart = 0
            txtPassword.SelLength = Len(txtPassword.Text)
            'Add 1 to Counter
            'PassCount = PassCount + 1
            'When Counter exceeds 3 show Msgbox
            If PassCount = 3 Then
                MsgBox "Three invalid login attempts... this program will now shut down", vbInformation, "Program shutdown"
                End
            End If
        ElseIf Response = vbCancel Then
            Unload frmPassword
            End
        End If
    End If
End Sub

Option Explicit takes care of those little problems. :rolleyes:

It gives an error, highlighting Static and the msg says "Invalid outside procedure" when doing that..
