dispose

Does the garbage collector clean up web service references or do I need to call dispose on the service reference after I'm finished calling whatever method I call? Dan Herbert Instead of worrying about disposing your web services, you could keep only a single instance of each web service, using a singleton pattern . Web services are stateless, so they can safely be shared between connections and threads on a web server. Here is an example of a Web Service class you can use to hold references to your web service instances. This singleton is lazy and thread-safe. It is advised that if you make

In this answer I found, Cleanup the unmanaged resources in the Finalize method and the managed ones in the Dispose method, when the Dispose/Finalize pattern has been used in your code. And later I found this nice article about finalize and dispose and got a clear idea about them. The article has the following code( Page 3 ), to explain the concepts: class Test : IDisposable { private bool isDisposed = false; ~Test() { Dispose(false); } protected void Dispose(bool disposing) { if (disposing) { // Code to dispose the managed resources of the class } // Code to dispose the un-managed resources of

I am confused about dispose. I am trying to get my code disposing resources correctly. So I have been setting up my classes as IDisposable (with a Dispose method) them making sure that the Dispose method gets called. But now FXCop is telling me lots of stuff about Disposing = false and calling Dispose(false). I don't see a Dispose method that takes a bool. Do I need to make one? If so, why? Why not just have a method that gets called when it is disposing? I saw some code here: http://msdn.microsoft.com/en-us/library/ms244737.aspx that shows how to make a Disposing method that takes a bool. It

Start with these simple classes... Let's say I have a simple set of classes like this: class Bus { Driver busDriver = new Driver(); } class Driver { Shoe[] shoes = { new Shoe(), new Shoe() }; } class Shoe { Shoelace lace = new Shoelace(); } class Shoelace { bool tied = false; } A Bus has a Driver , the Driver has two Shoe s, each Shoe has a Shoelace . All very silly. Add an IDisposable object to Shoelace Later I decide that some operation on the Shoelace could be multi-threaded, so I add an EventWaitHandle for the threads to communicate with. So Shoelace now looks like this: class Shoelace {

How can I dispose JFrame from another class? My code is listed below. I use Netbeans generate form for generate window. And I want dispose using another class(name is needDispose). public class needDispose { /** *Call for dispose frame */ public static void disposeMyFrame(){ myEasyFrame.getMainFrame.dispose(); // DOESNT WORK } } NETBEANS GENERATE (important method is getMainFrame() ) import javax.swing.JFrame; public class myEasyFrame extends javax.swing.JFrame { /* * Get frame */ public final JFrame getMainFrame() { return this; } /** * Creates new form myEasyFrame */ public myEasyFrame() {

I have researching through very simple code and get stuck on seeing the dispose() result of datatable Following is the code DataTable dt= new Datatable(); SqlCommand Cmd = new SqlCommand("sp_getData",SqlCon); SqlCommand.CommandType= CommandType.StroedProcedure; SqlCon.Open(); sqlDataReader dr= cmd.ExecuteReader(); dt.Load(dr); SqlCon.Close(); grdView.DataSource =dt; dt.Dispose() // Here I dispose the table as it is no use for me & wanna memory free from this But after disposing off the datatable i still found that it is still showing RowCount = 10k. Does Dispose() method does not free up the
