WorkerThreads updating WindowsForm field.

[Joshua Russell]

Firstly my main method is like this:

static void Main(string[] args)
{
// New Form Thread
FormHandler myFormHandler = new FormHandler();
ThreadStart myThreadStart = new ThreadStart(myF ormHandler.Show Form);
Thread formWorkerThrea d = new Thread(myThread Start);
formWorkerThrea d.Start();

// Main Thread Handler
MainThreadHandl er threadHandler = new MainThreadHandl er();
}

This opens an instance of a form that I use as a main interface with a
notify icon. it then makes a new instance of MainThreadHandl er causing my
thread handles to start. This is a TCP listener. It creates a new worker
thred for every incoming connection (server). I would like each server
thread created to update or cause the updating of a field in the main Form.
In effect I would like a field on the main form that tells me how manny
connections I have currently open.
Any one know how I can do this?

Hi Joshua,

I guess you will need to pass to the MainThreadHandl er
either the FormHandler instance or an object that holds a reference to
the form that you would like to update.

MainThreadHandl er threadHandler = new MainThreadHandl er(myFormHandle r);

Then, MainThreadHandl er's listener thread would do something like the
following to update the form:

_myFormHandler. MyUpdateFormMet hod();

The FormHandler.MyU pdateFormMethod () method updates the form.

Also, since you are updating the form's controls from another thread,
make sure you use Control.Invoke( ) in the method that updates the
form. (MyUpdateFormMe thod in the above example)
