Hi,

there is a buggy comment on your sites.

Please look at:
---------------
Site: http://homepages.borland.com/efg2lab/Library/Delphi/DatesAndTimes/
Name: TDateTimePicker
The comment in: Dave Nottage's UseNet Post about how to  force a
TDateTimePicker to drop down programmatically



The sample (to drop down programmatically) is buggy, because the button is
pressed continuous.

Better way, use:
----------------
DateTimePicker1.Perform(WM_SYSKEYDOWN, VK_DOWN, 0);

Because, the combination of ALT and the Keydown (Arrow) drop down the
ComboBox/DateTimePicker.
With WM_KEYDOWN you get all VirtualKeys (VK_) and with WM_SYSKEYDOWN (=
pressed ALT) the "SystemKeys".


Best regards,
Frank Aluttis
