Hello

I have a login screen containing a panel having two textboxes login and password and a login button

Now when a user enters the username and a passsword, and presses enter , he should automatically login, no need to use tab to go to the button , or use the mouse

How do I detect the "Enter" keypress and then automatically have the login button activated ?

Please help asap

Hi jbajaj,

For the form you are in, there is an AcceptButton property.  Set this in the properties window to the name of the Login button and you're done.

Cheers!

Or in code, if you prefer:

Me.AcceptButton = Me.Button1

Cool

I have two panels and each having two seperate buttons .
Only one of them is visible at a time

When one is visible I want it to have the accrpt button and vice versa

How do I do that

Is using a variable between them the only solution

When you make the panel1 visible, make button1 the acceptbutton,

Then when panel2 is made visible, make button2 the acceptbutton.

Then in that case
if panel1.Visible = true then
   Me.AcceptButton = Me.Button1
Else
  Me.AcceptButton = Me.Button2
End if

   Public Function KeyAscii(ByVal UserKeyArgument As KeyPressEventArgs) As Short
        KeyAscii = Asc(UserKeyArgument.KeyChar)
    End Function

    Private Sub TextBox1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles TextBox1.KeyPress
        If KeyAscii(e) = 13 Then
            MsgBox("you press ENTER key")
        End If
    End Sub

Or you can do something like...

    Protected Overrides Function ProcessCmdKey(ByRef msg As System.Windows.Forms.Message, ByVal keyData As System.Windows.Forms.Keys) As Boolean
        If keyData = Keys.Enter Then
            If Panel1.Visible Then
                Button1.PerformClick()
            Else
                Button2.PerformClick()
            End If
        End If
    End Sub
