VB 2010 - Express Webbrowser.Dispose Does Not Release Application Memory
Apr 13, 2010An application that has 3 Webbrowsers instantiated at design time navigates to webbrowser2 15 times every minute with a different webpage. Webbrowser2 is disposed of after each web page is received and processed. The size of the private application memory continues to grow as when the disposal was not instigated. The application memory grows to 1GB and then the program stops responding. Any suggestions? [Code]

Dispose Managed Objects In 2008?
Jun 1, 2011In My application, I have an MDI form. From MDI form I open all forms as child forms. I have implemented IDisposable for all large objects like file stream DB connection etc. In the Form_Disposed event I dispose all unmanaged objects. After the child form is closed, all unmanaged objects are disposed but managed objects (controls and form) are not disposed and still in memory. I find it from .Net Memory Profiler ([URL]).
So I have write code to remove all event handlers of all controls and form. Now, When form closed, dispose is called and all event handlers and controls are disposed, but controls and form are still in memory.
VS 2008 Call Dispose On Brushes?
Sep 16, 2009In my Zeal to get with the "Dispose" program, I implement a dispose pattern (still learning the ways and means of THAT) wherever it seems to make sense.I THINK I have the basic idea. However, I notice that, while Drawing.Brushes HAVE a Dispose method, when I call it, some sort of instability is created in Visual Studio itself, and i get the dreaded "Visual Studio has encountered an error and needs to close" splash screen, with no useable error information. SHould I assume that one should just NOT call dispose on Brush objects, or is there something I am missing here: [code]

View 6 RepliesVS 2008 DataTable Clear Or Dispose?
Feb 18, 2010I want to understand a situation; it's related to datatable clear().I have a code that populate a typed datatable from Excel in a separate thread using a backgroundworker. This works well, the table is filled and I can see the data. Now, I want to clear the data from table and restart the import. The operation is ten times slower than the first time. My datatable variable is declared like this:Private dt as new DataTable - not a local variableI want that all subs from class to be able to use the table, that's the reason I declared the table as private. What I want is to be able to create a new instance of dt (or clear allocated memory) - maybe this is the reason for slowdown.
View 2 RepliesVS 2008 Form Close Vs Dispose
May 6, 2009I am using VB.NET (Visual Studio 2008) and thus .Net framework 3.5. I have developed an application which has a MDI form and then has several other forms, most of which are shown using form.showdialog and some set of forms are shown using form.show. Whenenver a form (shown using form.showdialog) was closed (usually by clicking on a button (OK or Cancel)) I wrote code Me.dispose. After careful testing and R&D I figured this caused flickering on the screen. There use to be a flicker on the screen and it looked weird.

Jul 7, 2011I have prided myself in having a pretty clean code however in the game I am making I have a player view (showscreen) and a host view, which is a copy of the player view (on a smaller screen). This way the host can see what's going on.The problem is that the graphic doesn't dispose properly and Garbage Collector gets it, though I have noticed it will crash if GC doesn't get it in time. The larger the showscreen window the more junk gets put into memory, which sucks.I thought I had everything correctly disposed below but still doesn't get the job done.

.net - Dispose Of A Task?
May 13, 2011I am having fun working with System.Threading.Tasks. Many of the code samples I see, however, look something like so:
Dim lcTask = Task.Factory.StartNew(Sub() DoSomeWork())
Dim lcTaskLong = Task.Factory.StartNew(Sub() DoSomeWork(), TaskCreationOptions.LongRunning)
Task.WaitAll(lcTask, lcTaskLong)
That's the extent of the sample.Tasks implement IDisposable, so obviously I'm supposed to dispose of them, but what if I just want to "Fire and Forget"?If I don't dispose, will I leak threads/handles/memory/karma?Am I using tasks "wrong"? (Should just use a delegate and leave tasks alone?)

Appropriate Use Of Dispose Method
Jan 28, 2009When is it appropriate to apply the dispose method to controls?For example in a form that has five group boxes, once the first group box is used to gather user entries and is no longer needed, is it worth it to apply the dispose method to the first group box? Is it needed for local variables, for example a StringBuilder used within a private function which is only used while the function is executing?

Does The .dispose() Method Do Anything At All
Jan 7, 2010I was experimenting with ways to get rid of some memory leaks within my application the other day when I realized that I know virtually nothing about cleaning up my resources. I did some research, and hoped that just calling the .dispose() would solve all of my problems. We have a table in our database that contains about 65,000 records. Obviously when I fill my dataset from the dataadapter, the memory usage can get pretty high. When I called the dispose method on the dataset, I was surprised to find out that NONE of the memory got released.

Call Dispose With Regions?
Jun 22, 2011When you set a region equal to another, or set it equal to a new instance, do you have to call dispose on the region, or does VB do that? (I guess this isn't necessarily specific to regions)
ex:
'at some point in the code a region is created
Dim Rgn as New Region(SomeRect)
'....
[Code].....
If Rgn now points to the Rgns(0) clone, what happens to the original memory created by "New Region(SomeRect)"? Do I need to call dispose on Rgn before assigning it to the the Rgns(0) clone?
