DateTimePicker - setting the default month on DropDown

WinForms application in VB.Net...

I have a DateTimePicker in my application.  When the user drops down the dtp to reveal the calendar, I want to somehow set the default calendar month to the current month - irrespective of the current value of the dtp.

I want to do this without actually changing the dtp's value.  In other words, after dropping down the dtp, if the user decides not to change the date and clicks off the dtp without selecting another date then I want the date to remain the same as before the dtp was dropped down.

I hope that makes sense.

To clarify...

if the current date value is 1 January 2000, I still want the dtp calendar to show (by default) this month, ie October 2004 on DropDown.

Dim d As DateTime = DateTimePicker1.Value
DateTimePicker1.Value = Now.Month.ToString() + "-" + d.Day.ToString() + "-" + d.Year.ToString()

I don't want to change the value - I just want the drop down calendar to display THIS MONTH rather than the month of the dtp's current value.

I don't think it can be done without changing the current value.  Here is a way to store the current value and then put it back if the user clicks off the DTP without changing the value.  If you dismiss the dropdown with the ESC key though, that registers as a change so it doesn't work then.

Public Class Form1
    Inherits System.Windows.Forms.Form

    Private dtpValue As DateTime
    Private dtpChanged As Boolean

    Private Sub DateTimePicker1_DropDown(ByVal sender As Object, ByVal e As System.EventArgs) Handles DateTimePicker1.DropDown
        dtpValue = DateTimePicker1.Value
        DateTimePicker1.Value = Now
        dtpChanged = False
    End Sub

    Private Sub DateTimePicker1_ValueChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles DateTimePicker1.ValueChanged
        dtpChanged = True
    End Sub

    Private Sub DateTimePicker1_CloseUp(ByVal sender As Object, ByVal e As System.EventArgs) Handles DateTimePicker1.CloseUp
        If Not dtpChanged Then
            DateTimePicker1.Value = dtpValue
        End If
    End Sub

End Class
