There is a project [^]to port .NET Framework to Linux. I guess you should be able to run it on Mac OS X too. I don't think though they will ever port every class in .NET framework.

Here is an example:

MessageBox.Show(DateTime.Now.ToString("dd-MM-yy"));

One way to do it is to write a Browser Helper Object[^]. Browser Helper Object can then send message and pass URL to your main application.

P/Invoke

ShellExecute(0,"open","mailto:?file=\"c:\autoexec.bat\"", NULL, NULL, SW_SHOWNORMAL);

In C# threads are handled differently. You create an instance of System.Threading.Thread and pass ThreadStart delegate to the constructor. ThreadStart delegate represents a method that thread will run.

public static void RunMe()
{
{
//Run code here
}
}

public static Main()
{
Thread myTread = new Thread(new ThreadStart(RunMe));
}

I use TextPad too and very happy with it. It's fast and has lots of nice features.

If I understand you correctly, you need to know control which triggered context menu when you handle MenuItem.Click event. When you handle this event sender is a context menu so it wont't help you much. However, if you handle ContextMenu.Popup sender is the control triggering the event. What you can do is this: create a field in the class where you handle events object controlWhichTriggeredEvent; Then create a handler for ContextMenu.Popup:

private void YourContextMenu_Popup(object sender, System.EventArgs e)
{
    controlWhichTriggeredEvent = sender;
}

Now when you handle MenuItem.Click , controlWhichTriggeredEvent will contain the latest control clicked by user (you will have to cast it to label of any other control).
