multithreading

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 a System.Threading.Timer
use the IsInvokeRequired pattern so I will rely on the .NET ThreadPool.

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!

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language.
