Drop down a DTPicker from code?

[David Crowell]

Is there a method to drop down a DateTime Picker from code?

I assume that it'll be a SendMessage call, but I have no idea what message
to send. Any help would be appreciated.

Thanks,

Dave

Unfortunately, no direct way. However it's fairly simple to fake a
mouse click on the dropdown arrow button with mouse_event.

Using SPY++ I found that the DTP does not have a child buttion, but I was
able to get this to work with the following kludge...


Option Explicit

Private Const WM_LBUTTONDOWN As Long = &H201
Private Const WM_LBUTTONUP As Long = &H202
Private Const MK_LBUTTON = &H1

Private Declare Function SendMessage Lib "user32" Alias "SendMessageA"
(ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As
Any) As Long

Public Sub DropDTPicker(dtp As Object)

Dim Pos As Long

Pos = ((dtp.Width / Screen.TwipsPerPixelX) - 5) Or &H50000

SendMessage dtp.hwnd, WM_LBUTTONDOWN, MK_LBUTTON, ByVal Pos
SendMessage dtp.hwnd, WM_LBUTTONUP, MK_LBUTTON, ByVal Pos

End Sub

Hi Dave --

SendKeys "{F4}" (or equivalent WM_KEYDOWN/WM_KEYUP messages).

I was *really* pissed, myself, one day a few years ago, and just kept banging on keys
until something worked. <g>
