COM's Connection Point can become a callback mechanism for events.
The method of receiving time callback in VBS is
Function MyObject_onadd (V1, V2)
MSGBOX "Add" & V1 & V2END FUNCTION
Set cnxn4 = wscript.createObject ("atlcom.atl3", "myObject_")
Method used in page
Function TT_ONADD (V1, V2)
MSGBOX "Add" & V1 & V2END FUNCTION
Function test ()
TT.Add 1, 2
END FUNCTION
Script> span span>
Body> html>
Thanks to Kevin to give me the help.
