c# - Where should the thread / task be started to see if you are still connected to a device (model or viewmodel)? -

-

I have a C # / MVVM application that works with a device. This device needs to be constantly checked to connect / disconnect the device. I was given a code that starts a thread (USB connection code project) that will constantly try to see if the device is connected or not. It will then use the callback to view modal to set the properties needed to be set.

But should the ViewModel thread not start and then call the appropriate methods "USB connection code project" to check it?

If I keep the thread in the model, then reading the other thread should probably use INOTifyPropertyChanged instead of the representative / callback .... right?

In the current code absolutely is correct.

There is absolutely nothing to check for a USB device, with view or logic; So this model is in.

The utility INotifyPropertyChanged is really painful, and is not very clearly obvious. A representative or event callback is a completely proper notification mechanism to tell the model to update its status. I will not change anything about the design described.

In advance thank you If you have created a true asset in your class then You should be a great and setter, you can add the code directly to the form property in order to take action on the basis of "form": Public partial category Form 1: form {public form 1 () {InitializeComponent (); } // define car square public class car {public string name = string. Empty; } // private car to keep the value of the current car private variable _car = null; // Property of public form which you can ru...
