[RESOLVED] Sendkey

[rpc86]

Hi guys,

In VB6 I used Sendkeys "{Tab}" to place the cursor on the next control.

How will I do this in VB.NET ?

Private Sub txtUserID_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles txtUserID.KeyDown

        If e.KeyCode = Keys.Enter Then
              ' what will I add here ? 
        End If

    End Sub

Thank you very much.

you would want to use the SendKeys class similar to vb6. On a side note, to prevent the notorious ding you here when pressing enter, place the code in the KeyPress event and set e.Handled = true like so

    Private Sub TextBox1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles TextBox1.KeyPress
        If e.KeyChar = Chr(Keys.Enter) Then
            e.Handled = True
            SendKeys.Send("{TAB}")
        End If
    End Sub

Don't use SendKeys.Send for this. Call SelectNextControl.

Private Sub SelectNextControlOnEnterKey(ByVal sender As Object, _
                                        ByVal e As KeyPressEventArgs) Handles TextBox1.KeyPress, _
                                                                              TextBox2.KeyPress, _
                                                                              TextBox3.KeyPress
    If e.KeyChar = ControlChars.Cr Then
        Me.SelectNextControl(DirectCast(sender,  _
                                        Control), _
                             True, _
                             True, _
                             True, _
                             True)
        e.Handled = True
    End If
End Sub

You could use the KeyDown event and set e.SuppressKeyPress to True but the advantage of using the KeyPress event is that if you keep the Enter key depressed focus will continue to move from control to control, which is the same behaviour as the Tab key.

Note also the use of ControlChars.Cr, which is the first character of a Windows line break.

Good info, I never knew about the ControlChars enum.

It's not an enum. It's a class.
