Is there a way to dynamically set the default value of a DateTimePicker control?

Is there a way to dynamically set the default value of a DateTimePicker control.
So at start-up the date displayed is yesterday's date or one month ago.

this.dtPickStart.Value = new System.DateTime(2010, 11, 22, 0, 0, 0, 0);

Rather than a literal value as set in 'Properties'

I'm not sure what you are having problems with.
I did this in a Form Load event and it sets a DateTimePicker called DPTest to yesterday's date:

(C#)

DateTime  yesterday = DateTime.Today.Subtract(new TimeSpan(1)).Date;
DPTest.Value = yesterday;

(VB.NET)

Dim yesterday As DateTime = DateTime.Today.Subtract(New TimeSpan(1)).Date
DPTest.Value = yesterday
