>I am trying to install the Calendar Control. I think it is mscomctl2.ocx, but I can't find it on my harddisk. Do I have the name wrong?

It depends on which control you're refering to. If it's MS DateTimePicker control than you'll need MSCOMCt2.ocx. If it's MS Calendar Control than it's in MSCAL.ocx. Either one should be in the Windows system directory.
