Using .NET 1.1, Windows Forms

I have disabled the Tab key with the following code but how do I disable the Shift+Tab Key?

Thanks

San

 Protected Overrides Function ProcessDialogKey(ByVal keyData As System.Windows.Forms.Keys) As Boolean
        If Not _dt Is Nothing Then

            If keyData = Keys.Tab Then
                Return True
            End If

            Return MyBase.ProcessDialogKey(keyData)
        End If
    End Function

Could try:

Public Class Form2
    Private Sub Form2_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        Me.KeyPreview = True
    End Sub

    Private Sub Form2_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown
        If e.Shift And e.KeyData.Tab Then
            e.Handled = True
        End If
    End Sub
End Class

Thanks but your suggestion doesn't work.
If I press shift by itself or Tab by itself, then it works. But shift+ tab is still enabled.

It will work only if your all controls tab stop is set to False.

Now try this code

    Private Sub TextBox1_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles TextBox1.KeyDown
        If e.KeyCode = Keys.Tab And e.Shift Then
            Me.Text = "Tab +Shift"
        Else
            Me.Text = "Tab Only"
        End If
    End Sub

You can disable both Tab and Shift-Tab with this:

Public Class Form1
    Inherits System.Windows.Forms.Form

    Protected Overrides Function ProcessTabKey(ByVal forward As Boolean) As Boolean
        Return True
    End Function

End Class
