The ItemFound signal is wired to CoordinatorSearch.ItemFound. The purpose of the notification is to show the filename and the number of files found, requiring the UI to be updated. Since the NavigatorSearch.ItemFound signal is sent on a background thread, CoordinatorSearch must switch to the UI thread before forwarding ItemFound to ContentSearchResults. Listing 11-17 and Listing 11-18 show the details. Listing 11-17. How CoordinatorSearch Switches to the UI Thread Before Forwarding Notifications to UI Elements (C# Code) public class CoordinatorSearch { Control uiControl; public CoordinatorSearch(Control theUiControl) { uiControl = theUiControl; } public void ItemFound(string thePath, int theCurrentCount) { FireItemFound(thePath, theCurrentCount); if (theCurrentCount == 1) FireMessage("1 item found"); else FireMessage(string.Format("{0} items found", theCurrentCount)); } public delegate void ItemFoundHandler(string thePath, int theCurrentCount); public event ItemFoundHandler OnItemFound; void FireItemFound(string thePath, int theCurrentCount) { if (OnItemFound != null) uiControl.Invoke(OnItemFound, new object[] {thePath, theCurrentCount}); }
