I am not sure how the user defined class objects are garbage collected. Do I need to implement IDisposable interface on every class and call the dispose() method on it to free the memory?

I am following directions on the set up of my application and they make no mention of implementation.
When to use Abstract class and when to use Interface class.
View 10 RepliesI have a block of SQL statements that I like to use as a sort of function.
I was thinking that I could make a class and inherit all of the master function, then add the parts that I need for other sections of the program in a sub class.
The problem is, up to this point I've been programming ASP .Net through visual studio, and it's kind of just programming behind controls. I'm not sure where to put the class/function/method/interface, or whatever we call it.
Of course you probably know that visual studio creates a bunch of partial classes when you do an ASP. Net application... so.. to get access to a function like object, across classes.. use an Interface?
I have created a Slider User Control which implements ISlider Interface.I have some methods like SetValue below which should accept both ISlider types and standard Slider control type.Am I'm obliged to use this heavy syntax is there any shortcut?
public void SetValue(Object slider, Double value)
ISlider ISlider;
ISlider = slider as ISlider;
if (ISlider != null)
ISlider.Value = value;
((Slider)slider).Value = value;
There is a SearchPage which has a properties ErrorMessage, SuccessMessage etc. This is basically a MVP pattern so for each page(view) there is IView that contains definitions for all the properties
I am using decoratoe pattern to set these peoperties dependingon the message type. There is another Interface IBaseMessage which has a method DisplayMessage() and a class BaseMessage which implements the interface. This class has a definition of the view
Interface IbaseMessage
{
DisplayMessage()
}
baseMessage:IbaseMessage
{
public Iview _view{get; set;}
DisplayMessage()
{
_view.Warning ="<message>"
_view.error="<message>"
}
Here, I am not able to set the message to the view properties. I am getting the error as "Object reference not set to an instance of the object"

I've got an ASP.NET application that I installed by creating a web setup. I ran into a problem where ASP.NET wasn't registered with IIS so it gave me a "installation was interrupted" message that told me exactly nothing. Anyhow, I finally got it installed, and I can access the main page, but it's telling me that my class isn't defined. The dll is in the same directory as the Default.aspx page
Here's the main error information

I've made an interface called ApprovalEvent in a separate file with the namespace myproject... I've also made a class called PurchaseOrder... it's also in the same namespace, just in a separate file. Whenever I try to make PurchaseOrder implement ApprovalEvent it always says that ApprovalEvent is undefined...
How can I make the class recognize that the interface exists but is in a different file?

I include the global style sheet file on the master page's 'head' section, but the child pages show an underline on the class parameters I put on the HTML elements (and they show as 'warnings' in the error list). It still works and the styles do get applied, but how do I tell the pages that their master page has the style definition? (and I don't really want to add the global CSS file to every child page, that should be one of the perks of the Master pages)
View 1 RepliesI am using VS2010 and am creating an ASP.Net application.I have declared a class called "Calculator" in a class file called "Calculator.cs" in the App_Code folder.I have a form called "CalcDemo.aspx" with a code behind file.

The namespaces are the same like Webapp1.xxxx
I am just starting with Crystal Reports and have been scanning articles on the web. I'm using the Push model so need to connect to a DataSet. All the articles I'm reading talk about creating a Crystal Report, for example, myCrystalReport.rpt. I have done this, connected my DataSet schema (.xsd file) to the report and actually get a pretty well formatted output in the Report Previewer in VS 2008. The problem is that in order to actually connect data to the report, I need to instantiate a myCrystalReport object. In the examples I've seen, there appears to be an autogenerated .cs class like code-behind for myCrystalReport. I do not get that, only the .rpt file. Is there something wrong with my VS configuration or do I need to take specific action to get

View 1 RepliesI have a hierarchy in my website project as below:
[CustomControl1 - folder]
- CustomControl1.ascx
- CustomControl1.css
- CustomControl1.js
I load css and js files dynamicaly based on which controls are used on particular page. I am doing it by using following code:
[code]....
where AddLinks method adds HtmlLink controls to Page.Header with href attribute set to coresponding css and/or js file.
I would like to add Interface that would force new controls to have AddLinks method but it is impossible since it is a static method. Because my custom controls inherit from Control class I cannot use abstract class and/or virtual methods either. How can I achieve my goal?

Label foo = new Label(); //Where this is an ASP.NET web forms label
Do I need to call dispose on these web forms labels? Also, how late in the page life cycle is it safe to call Dispose on these? If a class implements IDisposable, but doesn't actually do anything in it, is there any harm in not calling dispose?
(Yes, I have already read that closing connections is a good thing and using blocks are a good thing, too.)
DataSet is another class that seems to implement IDisposable for inexplicable reasons.
One thing I would like to improve on for many of my web applications, is the user interface design and the "look and feel" of the sites. To begin looking at how to do this, I thought I would start by asking the community what additional software they use or would recommend to combine with either VS2008 or VS2010.
