Question

I have a MDI WinForms application that can perform several tasks. Each task is running as a backgroundWorker.

What is the good approach to control the running threads:

• check whether the specific thread is running
• stop specific thread ?

For example it shouldn’t be possible to run the same task simultaneously.

May be I need a separate class where I can store isTaskRunning variable?

How is the good way to do this?

TIA

Answer 1

One approach you could take would be to create a class per task. Then let that class perform the tasks. It will know if multiple tasks could be used at once, and restrict access to each of them. Hence :

public class LongUploadTask
{
  private bool isRunning;


  public void Execute()
  {
    if(!isRunning)
    {
       //etc...
    }
  }
}

Note, I have left out locking code if you are accessing this from multiple threads, which I don’t think you are. In addition, if you wanted to execute this asyncronously, you could use asynchronous delegates and manual reset events to achieve what your BackgroundWorker’s are doing.
