hi,

i just test DateTimePicker Control. it seemīs me like a Dropdown Combobox.

If i use it with FlatEdit in a Form, and User reach DTP Control, he/she have to press Dropdown Button.

now i try to "Popup" DateTimePicker "WHEN" Control become Focus ( i meen simulate "Dropdown") but Control does not react on: PostAppEvent -> SendMessage

PostAppEvent( xbeP_Keyboard,xbeK_ALT_DOWN,,oDate) where oDate is my activeX Control.

i also read about :DroppedState := True and :SetDropDownListStyle(True)
but it seemīs not belong to DateTimePicker Control

i think i send my xbeK_ALT_DOWN Event to wrong Object oDate ... oDate:Combobox ???

is there a Solution ?

Hi,
 
Try to call
DefWindowProc(WM_SYSKEYDOWN, VK_DOWN, 0);
for Picker.

http://msdn.microsoft.com/de-de/library/ms633572(en-us,VS.85).aspx

it is the oDatePicker:hwnd so you can use

//
// this will "open" DropDown of DatePicker Combobox
//
SendMessageA(oPick:hwnd, WM_SYSKEYDOWN, VK_DOWN,0)
