I am building a WinForms application reading from a socket data and charting lines.
I am using System.Windows.Forms.Timer to trigger each second the event that

  • gets data from a queue filled by a socket
  • redraws lines on the chart

My Question is about the Timer object: I have one Timer object for each WinForm having a chart to redraws; so suppose I have 20 chart, I will have 20 forms with a total of 20 Timers.

Is this a good approach? I decided this based on the following(please correct me if I am wrong )

  • Forms.Timer instance doesn’t create a Thread on my application, but just triggers the event on receiving a WM_TIMER event from the message pump of the Form.
  • it lives in the same thread of the GUI so I can directly access each element of my forms without worrying too much.

Are too much timers a good approach or could I have drawback?
Thanks

    This is a good approach, although you might want to reuse the timers instead of making a separate timer for each form.
    For example, you could make a static Timer object and add a Tick handler in the form constructor. Remember to unsubscribe from the event when the form closes (in Dispose or OnClose), or your forms will never die.
