You will need to delete the calendar contol from those forms - not the name of it though - as you do not have the same version of the Calendar Control that the examples use.
Then, in your form's design, go to Insert -> ActiveX control and pick Calendar. Rename and resize the calendar to fit on your form.
If you don't have the Calendar ActiveX control then you'll either need a full install of Access or find somewhere that it can be downloaded from.
