Luís, this is a "simple example for create programmatically a Form with a Timer" that displays a messagebox every time it is fired (for 30 minutes, Interval property should be set to 30 * 60 * 1000 - for testing purposes, it is set to 10 seconds interval). As you can see, until the user reacts to the messagebox, the interval for the timer is not reset and the form does not respond to user interaction. This may be or not what you pretend.

If you intend to perform a query at a regular interval, you probably should isolate the query in its own private session, to prevent it confuse the application flow.

LOCAL loForm AS aFormWithATimer

m.loForm = CREATEOBJECT("aFormWithATimer")
m.loForm.Show(1)

DEFINE CLASS aFormWithATimer AS Form
	ADD OBJECT theTimer AS aTimer
	ADD OBJECT cmdQuit AS CommandButton WITH Caption = "Close"
	ADD OBJECT txtInput AS TextBox WITH Top = 30

	Fired = 0

	FUNCTION cmdQuit.Click
		Thisform.Release()
	ENDFUNC

ENDDEFINE

DEFINE CLASS aTimer AS Timer

	Interval = 10000

	PROCEDURE Timer
		Thisform.Fired = Thisform.Fired + 1
		MESSAGEBOX("This is modal, timer will not re-run until user reacts..." + TRANSFORM(Thisform.Fired))
	ENDPROC
