I wish to open a TDateTimePicker with code. How may this be accomplished? (The DropDown method does not work for this component, before you try!)

Well done, Ronit!!

Why don't you comment the code a little so that we may benefit from your considerable wealth of knowledge? The two API calls are quite cryptic without any explanation.

Regards,

Edward

Ronit,

I just noticed that the code only works if the picker tpype is set to date; how does one open it if the type is set to Time?

When you are focused on any combobox, and you press F4, the combo drops down. This code simulate the keystroke F4:
line 1 - setting the focus
line 2 - simulating F4 key down
line 3 - simulating F4 key up

If you set to Time mode, you cannot open a combo, even by clicking it, cause there is no combobox in time mode, or any other 'dropping' time screen.
