Change the WinTracker constructor to remove the WinExerciseForm parameter and replace it with a callback function that takes an int parameter and has no return value (void). Do not define a custom delegate type, but instead use Action<…>. The delegate should be saved to a class field variable and then used in the track bar's Scroll event to pass the track bar value back to the WinExerciseForm instance through the callback function. The constructor call in the WinExerciseForm class will have to be updated to pass the delegate for the update progress bar method. Since the callback function delegate in the WinTracker's class field is only assigned once and not changed after that, make the class field readonly. 11Enamespace WinExercise124 referencespublic partial class WinTracker : Form{1314private WinExerciseForm m_parent;1 referencepublic WinTracker(WinExerciseForm parent){InitializeComponent();1516171819m_parentparent;20}211 referenceprivate void tbMaster_Scroll(object sender, EventArgs e){m_parent.UpdateProgressBar(tbMaster.Value);}222324252627} Enamespace WinExercise{11125 referencespublic partial class WinExerciseForm : Form{private WinTracker m_tracker;131415161 referencepublic WinExerciseForm(){InitializeComponent();17181920m_tracker = new WinTracker(this);m_tracker.FormClosed += m_tracker_FormClosed;}2122
