C# Message box on top until action done

How can I open a MessageBox , keep it open until a task finishes, and then close it.

I plan to insert a loading animation inside it.

I need to somehow make it that you cannot close it by clicking it, just through the code.

var t = Task.Run(() =>
{
    MessageBox.Show("Loading!");

    CycleValue = 0;
    while (CycleValue < noOfCycles && buttonStartStop.Text == "Stop")
    {
        this.Invoke((MethodInvoker)delegate
        {
            gm.NextState();
            CycleValue++;
            if (CycleValue == noOfCycles)
            {
                buttonStartStop.Text = "Start";
                buttonRandomise.Enabled = true;
                buttonReset.Enabled = true;
            }
        });
    }
});

You need to create your own form/window that mimicks the look of the message box, but that you have more control over (eg implementing a closing event after a task has completed). A label and a couple of buttons shouldn't take too long, and will be useful in future projects!

IF you want to show the busy cursor while an action is being performed on UI you can use -

 Cursor.Current = Cursors.WaitCursor;

If you want to show an animation refer this
