i am running 2 programs under win98 one is a Visual Basic program (drawing
graphs)
and the other is in dos mode (data entry of the graphs)
my problem is :
when the data in the dos entry screen changes
i want the graph to be updated automatically (on the graph program)
i tried to use a timer to check the data every minute but it causes
the both dos entry screen and the graph program to be slow
is there another way to tell the graph program that the data has changed
only when it is changed (not every minute) from the dos program

ps : i am using two screens on my machine one for the dos program
and the other is for the visual basic graph program
