Cross threading in class library

MAP Tiger

Hi I am working with iTunes library. I am supposed to implement it into a class library. The problem is that to respond to events associated to iTunesApp I had to disable CheckForIllegalCrossThreadCalls but however in class library, this property isnt supported. Now, I am stuck in between and not able to figure out the solution. Please help me that how to enable Cross thread operations or how to call the event safely without compromising cross thread restriction. I would be very thankful for your kind response. Thanks MAP Tiger

When a function is called on a background thread, just post to the synchronization context:

void SomeFunctionOnABackgroundThread()
{
SynchronizationContext.Current.Post(DoSomethingOnCorrectThread, "hello");
}

void DoSomethingOnCorrectThread(object state)
{
Console.WriteLine(state); // prints "hello"
}

The above code works for both WPF and WinForms.

Hi Thanks for the reply. I actually needed it in class library which will be basically hosted as a BHO to IE. Moreover, I have solved the problem and mentioning that here so may be useful for any other person.

        SongName = "Artist: " + myTrack.Artist + " - Name: " + myTrack.Name;
        Thread myThread = new Thread(ChangeText);
        myThread.Start();

SongName is defined on class level and ChangeText procedure do the work needed with SongName Now the other question needs attention which is about invoking javascript function if someone can do help. Regards,
