Hi all
I have a WinForm drawing a chart from available data.
I programmed it so that every 1 secong the Winform.Timer.Tick
event calls a function that:
- will dequeue all data available
- will add new points on the chart
Right now data to be plotted is really huge and it takes a lot of time to be executed so to update my form. Also Winform.Timer.Tick
relies on WM_TIMER
, so it executes in the same thread of the Form.
Theses 2 things are making my form very UNresponsive.
What can I do to solve this issue?
I thought the following:
- moving away from usage of
Winform.Timer
and start using aSystem.Threading.Timer
- use the
IsInvokeRequired
pattern so I will rely on the .NETThreadPool
.
Since I have lots of data, is this a good idea? I have fear that at some point also the ThreadPool will be too long or too big.
Can you give me your suggestion about my issue?
Thank you very much!
