Using DebuggerBrowsable Attribute for a better view in debugger window

Daily Coder | Jan 23, 2010 |

There are lots of small tricks in .net which can be very useful if used wisely. In this post I want to discuss the use of DebuggerBrowsableAttribute. Using this attribute you can control how a member of class will be displayed in debugger windows during debugging. Before that consider small example:

public class Organization
{
    public List<Employee> Employees
    {
        get;
        set;
    }

    public Organization()
    {
        this.Employees = new List<Employee>();
    }
}

JavaScript Exception Handling Techniques

Like the Object oriented programming the exception handling is also not used while coding in JavaScript. That why in most of cases if there is any problem in one part in a page then surprisingly other part also stops working. In this post we will be discussing the various techniques to handle exceptions in JavaScript.

Using try..catch block

try..catch block in JavaScript is very much similar to the regular C# try..catch block. The suspected code will be put in try block and all exceptions which will occur in the try block will be caught in catch block.

window.onload = function()
{
    try
    {
        var x = 90;
        var value = x / y;
    }
    catch(err)
    {
        document.write(err.name + ": " + err.message + "<br/>");
    }
}
Output:
TypeError: 'y' is undefined

Top 5 Small but Must have Extension Methods

In this post I want to cover some very basic and small extension methods which are very useful for any developer. All below mentioned extension method are not doing any complex operation. Rather they are just performing very simple task which you generally encounter a lots of times in your day today coding.

Download Source Files

1. IsNull

This is probably most commonly used expression. A lots of places in out code we check to null references. We usually add the obj == null or obj != null check to do this. Here is the IsNull extension method

public static bool IsNull(this object source)
{
    return source == null;
}

Using the you can avoid the lazy null check. Example:

public void ProcessData(DataSet input)
{
    if (!input.IsNull())
    {
        // business logic here
    }
}

Vista had come with new and cool look & feel. If you want to add the Vista Aero style theme to you WPF application running on Window XP then it is very easy trick. You don’t need any third party library or tool to achieve this.

To do this all you need to do is to add following lines of xaml code into the designer of your window right after window tag:

<ResourceDictionary Source="/PresentationFramework.Aero, 
   Version=3.0.0.0, Culture=neutral, 
   PublicKeyToken=31bf3856ad364e35, 
   ProcessorArchitecture=MSIL;component/themes/aero.normalcolor.xaml" />

If you want to apply this look through out the application then add this to app.xaml under <Application.Resources> section.

Purely CSS Callouts

Daily Coder | Oct 16, 2008 |

16 Comment(s)

This article explains how you can create callouts using CSS and without using a single image. This will use the CSS thick border technique for creating slant area. Look at the callouts below:

Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Aliquam dignissim tincidunt turpis. Mauris pede. Vestibulum gravida magna id nibh. In nec urna. Sed ut purus. Duis sit amet lacus ornare massa mattis consequat. Donec nec tellus. Nam quis nulla viverra diam faucibus dictum. Nulla facilisi. Donec sit amet dolor at sapien accumsan consectetuer.

Ramesh Soni Said

This callout is created only using CSS. The arrow shown in the callout is basically a DIV with thick up border and transparent left and right border.
