Lets says we have 2 objects, Broadcaster and Listener. Broadcaster has an event called Broadcast to which Listener is subscribed. If Listener is disposed without unsubscribing from the Broadcast event it will be retained in memory because of the event delegate referencing it that Broadcaster contains. What I'm curious about is if Broad...

Possible Duplicate: Should I Dispose() DataSet and DataTable? OP comment: I would like to say that the "Should I Dispose() DataSet and DataTable?" link isn't a possible solution. It's a good link, but this is more design related. Instead, ignore that the exposed property is a DataSet and replace it with something that should ...
How to implement the Dispose(boolean) at a UserControl... when the VS Designer already implemented it with a DebuggerNonUserCode attribute? Will my modifications on this method removed? (code from UserControl.Designer.vb) <System.Diagnostics.DebuggerNonUserCode()> _ Protected Overrides Sub Dispose(ByVal disposing As Boolean) ...
I asked a question earlier today, but I think I need to approach it in a different way (on top of that there was a "hang up" in regards to DataSet). Here's a class that encapsulates the creation of a Font (in other words, it is reading data from an xml file and is creating a font, at runtime, based on what it reads from that file): pub...
I have a WindowsForm with a panel control which I use to display my UserControls.

Hello, I must add some Dispose code to a class that inherits from a class that already implements IDisposable so I tried to do an Override of the Dispose method but I have not available the disposedValue because it is declared as private. How can I add the new Dispose statements? Protected Overridable Sub Dispose(ByVal disposing As Bo...
I have an application I am making that creates a large number of windows controls (buttons and labels etc). They are all being made dynamically through functions. The problem I'm having is, when I remove the controls and dispose them, they are not removed from memory. void loadALoadOfStuff() { while(tabControlToClear.Controls.Count ...
I have the following class public class Presenter: IDisposable { public IView View {get;private set;} //snip other object reference, all managed public Presenter(IView view) { View=view; View.MouseUp += MouseUpEvent; } public void MouseUpEvent() { //do whatever you want to do on mouse up } public...
I got a .net WinForms application. I have a UserControl which gets instantiated based on user action - upon instantiation, it performs some time-consuming tasks on a background thread (using BackgroundWorker), while displaying the ajaxy spinning animation. The user can click away at anytime, then click back onto the user control (which...
I have this code: Dim xx as image xx = image.fromfile(Fileloc) picturebox.image = xx And i can't delete the file even though I've loaded it into a picture box. If I add this line: xx.dispose the picture box becomes a big red X. I only want to delete the images when my application is closing (they are temp files). So shall I just...

My WCF service is IDisposable because it uses a ReadWriterLockSlim. When I dispose both of them in the following method: public void Dispose() { lockSlim.Dispose(); } Some of the public methods are still running (or accepting new connections, I don't know), and it fires exceptions because of the attempts of using disposed objects ...

In one of my SharePoint apps, I am getting this warning & stacktrace over and over (with different GUIDS): since it's only one of my apps, I assume there's something in my project's code, but SPDisposeCheck returns cle...
Should be an easy one. Let's say I have the following code: void Method() { AnotherMethod(new MyClass()); } void AnotherMethod(MyClass obj) { Console.WriteLine(obj.ToString()); } If I call "Method()", what happens to the MyClass object that was created in the process? Does it still exist in the stack after the call, even thou...

(Thats the point why I can't post my code here, sorry). Now, I have the problem, that somewhere in development (just refaktoring) the form stopped closing co...
