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?
View 1 RepliesDoes 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.

Oct 14, 2009I have 2 question, hope somebody give me an explanation: 1. Should a local variable call dispose method and set to nothing? 2.

View 4 Replies.net - Will SqlConnection's Dispose Method Interfere With Connection Pool
Jul 20, 2011From my understanding, .Net will pool SqlConnection objects where the Connection String is the same by default. Will the connection still be pooled if I call the Dispose method? This question is asked under the context of an ASP .Net application that at times makes many hits to the database in a single PageLoad event. I want the connections to be pooled, but would like confirmation that Closing and Disposing of the connection once the data operation is complete does not interfere with .Net's handling of the connection pool.
View 3 RepliesC# Event Handlers Automatically Created By WinForms Designer?
Jun 18, 2010Just moved from VB.NET to C#.In VB to connect and Event Handler to a Sub we use the Handles clause.From what it seems, this do not exist in C#. After creating a simple application with a button I realize that Window Forms Designer automatically created an EventHandler to my button1_Click function (after I double clicked it), in Form1.Designer.cs with this code:
this.button1.Click += new System.EventHandler(this.button1_Click);
But, in VB, the WinForms Designer create the Handles clause in my class, in the function header. So, C# create the default EventHandler in designer file, while VB creates in main class where control resides.

.net - Hide A Property From Going Into The Form Designer File?
Dec 17, 2010I am working in VB.NET 2010 Framework 2.0.
I don't want to allow some properties from going into form's designer file but the those properties will present on the form(property grid). The behavior of these properties will be same always.
I used the following code:
<DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)>
Public Property GradientBegin() As Color = Color.Red
But the problem I am facing is that -> on the property grid after changing the "GradientBegin" color to other than RED and compiling the program, it is replacing the new changed value to RED again. So I am not able to change the color actually.

C# - Why All The Event Checks In The ButtonBase WndProc Method - .Net WinForms
Aug 3, 2010I'm creating a base class for a button that inherits from Control as opposed to ButtonBase.
I'm using reflector to look at ButtonBase to make sure I don't overlook anything important and I'm puzzled with the contents of the WndProc method. There's checks in there for things like button up, click and capture changed, which as far as I can tell are all handled within the relevent 'On' methods of the class.
