Let see your code, how you have done all that.

THAT IS THE FUNCTION....

Public Function ValidatecboKey(ByVal KeyChar As String, ByVal cbo As ComboBox) As Boolean

        KeyChar = Mid(cbo.Text, 1, cbo.Text.Length - cbo.SelectionLength) + KeyChar

        Dim Index As Integer = cbo.FindString(KeyChar)

        If Index < 0 Then
            Return True
        End If

        Return False

ND USING IT LIKE

Private Sub cboBankID_KeyPress(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles cboBankID.KeyPress
        If Asc(e.KeyChar) = 8 OrElse Asc(e.KeyChar) = 27 Then
            e.Handled = False
        Else
            e.Handled = Admin.ValidatecboKey(e.KeyChar.ToString, cboBankID)
        End If
    End Sub
