vb.net - Automatically refresh -

i want inquire how auto refresh/update listview using timer in vb.net.. give me thought or steps, or code. here's code in timer:

private sub form1_load(byval sender system.object, byval e system.eventargs) handles mybase.load conn.open() timer1.enabled = false timer1.interval = 5000 dim strquery string = "select * " & _ "from software " dim mycommand new odbccommand(strquery, conn) dim myreader odbcdatareader myreader = mycommand.executereader listview1.items.clear() if myreader.hasrows = true 'listview1.beginupdate() while myreader.read dim listview listviewitem listview = listview1.items.add(myreader("log_type").tostring()) listview.subitems.add(myreader("log_desc").tostring()) listview.subitems.add(myreader("log_details").tostring()) listview.subitems.add(myreader("log_date").tostring()) listview.subitems.add(myreader("software_desc").tostring()) listview.subitems.add(myreader("software_name").tostring()) listview.subitems.add(myreader("develop_date").tostring()) listview.subitems.add(myreader("last_update").tostring()) end while end sub private sub timer1_tick(byval sender system.object, byval e system.eventargs) handles timer1.tick timer1.interval = 1000 timer1.enabled = false listview1.refresh() listview1.items.add(datetime.now.tolongtimestring() + "," + _ datetime.now.tolongdatestring()) end sub

this timer doesnt work. there way auto update or auto refresh listview?.

you need enable timer 1 time again @ end:

timer1.enabled = true

if not, timer wont work. timer1.enabled = false desactivate timer.
