I am using Delphi 3 Professional

I am getting an error with DateTimePicker

When you enter a single digit in the year section
you will get a stackoverflow error.

I am not positive, but looking at the code it looks like a bug in the control itself, not the VCL wrapper.  It only occurs if you dont type the 0 in before the 1 (or anything else for that matter).  Still trying to figure it out.  Just want you to know someone is working on it.

Can you force users to use the pull-down calender instead of typing in the date?
I tried to look for a way, but found nothing to do that.

There is a known Y2K bug with the TDateTimePicker that is fixed in an update to the common controls dll (comctl32.sdll) on microsoft.com. Perhaps it fixes this bug as well...

The TDateTimePicker uses the global variables know in SysUtils to set the time properties, that's why I do not have this problem.

If you use the ShortDateFormat and LongDateFormat global variables, you can try match "yy" and then replace it with  "yyyy".

There is still a bug though setting the MinDate property to the current value, where an error is raised with a message like "Dato is below 1/1 1899".

Williams
