> How can I use a calendar like in the Thread Filter in this forum ?

inserting it on the form is pretty much the same as described in your treeview question.
(thread 93400).
Look for the date time picker in the controls list.
You need to use the year, month and day values of that control to add the date to the field.
like in:
replace (this.controlsource) with date( this.year, this.month, this.day)
