Visa serial communication in event structure

[SaranVenkateshS]

Hi i try to transmit the string in Serial using Event Structure . 

Its wirking Fine .. But (Its in ValueChange Event only ).

But i need to use it in Mouse Down Event.

If i use Mouse Down event . it takes double press to do operation. !!!!

Hi saran,

why do you need any VISA communication in your event structure?Why not use a queue driven state machine?

Why do you need to use MouseDown events? What's wrong with ValueChange events?

Hi GerdW,

why do you need any VISA communication in your event structure?

I need to avoid CPU usage (instead of polling method)

Why not use a queue driven state machine?

I need to use Event Structure . like data received means . can collect (kind of interrupt  based receiption)

Why do you need to use MouseDown events? What's wrong with ValueChange events?

i think u know . whats diffference between Value change Event and Mouse Down (Or Mouse UP) Event

No need to have the VISA communication in your event handling loop. Use a queue driven state machine…

Yes, I know.

But why do you need to use MouseDown events in favor of ValueChange?
