Subtracting Dates

[Tigerweld]

I am stumped. I need to be able to subtract two dates and have the results in hours.

#include <GuiConstantsEx.au3>
#include <GuiDateTimePicker.au3>
#include <WindowsConstants.au3>

; Create GUI
$hGUI = GUICreate("DateTimePick", 400, 300)
$hDTP = _GUICtrlDTP_Create($hGUI, 10, 10, 250)
GUISetState()

; Set the display format
_GUICtrlDTP_SetFormat($hDTP, "ddd MMM dd, yyyy hh:mm ttt")


; Create GUI
$hDTP = _GUICtrlDTP_Create($hGUI, 10, 50, 250)
GUISetState()

; Set the display format
_GUICtrlDTP_SetFormat($hDTP, "ddd MMM dd, yyyy hh:mm ttt")


; Loop until user exits
Do
Until GUIGetMsg() = $GUI_EVENT_CLOSE

I believe the _DateDiff UDF will do this for you.
