The final thread-centric topic we will examine in this chapter is the CLR thread pool When you invoke a method asynchronously using delegate types (via the BeginInvoke() method), the CLR does not literally create a brand-new thread For purposes of efficiency, a delegate s BeginInvoke() method leverages a pool of worker threads that is maintained by the runtime To allow you to interact with this pool of waiting threads, the SystemThreading namespace provides the ThreadPool class type If you wish to queue a method call for processing by a worker thread in the pool, you can make use of the ThreadPoolQueueUserWorkItem() method This method has been overloaded to allow you to specify an optional SystemObject for custom state data in addition to an instance of the WaitCallback delegate: public sealed class ThreadPool { ...

public static bool QueueUserWorkItem(WaitCallback callBack); public static bool QueueUserWorkItem(WaitCallback callBack, object state); } The WaitCallback delegate can point to any method that takes a SystemObject as its sole parameter (which represents the optional state data) and returns nothing Do note that if you do not provide a SystemObject when calling QueueUserWorkItem(), the CLR automatically passes a null value To illustrate queuing methods for use by the CLR thread pool, ponder the following program, which makes use of the Printer type once again In this case, however, you are not manually creating an array of Thread types; rather, you are assigning members of the pool to the PrintNumbers() method: class Program { static void Main(string[] args) { ConsoleWriteLine("Main thread started ThreadID = {0}", ThreadCurrentThread.

GetHashCode()); Printer p = new Printer(); WaitCallback workItem = new WaitCallback(PrintTheNumbers); // Queue the method 10 times for (int i = 0; i < 10; i++) { ThreadPoolQueueUserWorkItem(workItem, p); } ConsoleWriteLine("All tasks queued"); ConsoleReadLine(); } static void PrintTheNumbers(object state) { Printer task = (Printer)state; taskPrintNumbers(); } }.

This looks very similar to our last example, but let s look at the differences. We ve added variables to hold our Workspace and Connection objects, as previously noted. We ve also added the sConn variable to hold our connection string. This is where we ll tell our Connection object where to find the data we require. The last difference is that we ve added a variable, iFieldCount, to hold the number of fields in our Recordset object. Copy and paste the path string and worksheet setup code from the previous example: 'store path to Access 2007 and 2000 versions of Northwind db arr_sPath(0) = "C:\projects\Excel2007Book\Files\northwind 2007.accdb" arr_sPath(1) = "C:\projects\Excel2007Book\Files\northwind.mdb" Set xlSheet = Sheets("Sheet1") xlSheet.Activate Range("A1").Activate Selection.CurrentRegion.Select Selection.ClearContents Range("A1").Select Set the connection string: sConn = "ODBC;Driver={Microsoft Access Driver (*.mdb, *.accdb)};" & "DBQ=" & arr_sPath(0) Instantiate the Workspace and Connection objects: Set wrk = CreateWorkspace("", "", "", dbUseODBC) Set cnn = wrk.OpenConnection("", , , sConn) We use the Workspace object s OpenConnection method to create the Connection object. Next we ll use the Connection object s OpenRecordset method to fill our recordset with data from the Employees table: Set rs = cnn.OpenRecordset("SELECT * FROM Customers", dbOpenDynamic) Insert our column headings using the iFieldCount variable: iFieldCount = rs.Fields.Count For i = 1 To iFieldCount xlSheet.Cells(1, i).Value = rs.Fields(i - 1).Name Next i xlSheet.Range(xlSheet.Cells(1, 1), _ xlSheet.Cells(1, rs.Fields.Count)).Font.Bold = True Our first example used a zero-based counter to do this job: For i = 0 To rs.Fields.Count - 1 xlSheet.Cells(1, i + 1).Value = rs.Fields(i).Name Next i

At this point, you may be wondering if it would be advantageous to make use of the CLRmaintained thread pool rather than explicitly creating Thread objects. Consider these major benefits of leveraging the thread pool: The thread pool manages threads efficiently by minimizing the number of threads that must be created, started, and stopped. By using the thread pool, you can focus on your business problem rather than the application s threading infrastructure. However, using manual thread management is preferred in some cases, for example: If you require foreground threads or must set the thread priority. Pooled threads are always background threads with default priority (ThreadPriority.Normal). If you require a thread with a fixed identity in order to abort it, suspend it, or discover it by name.
