Exploring Assembly in .NET

The Intermediate Language Disassembler (ildasm.exe),which comes with the .NET SDK allows to view a dll contents,manifest CIL code and Metadata…

ildasm can be loaded from command prompt(start –> Programs –> Microsoft Visual Studio 2008 – > Visual Studio 2008 Command Prompt

for demonstration i have developed a class with contains a method for getting the TotalPrice

   1: using System;

   2: using System.Collections.Generic;

   3: using System.Linq;

   4: using System.Web;

   5:  

   6: namespace www.buddhasmiles.blogspot.com

   7: {

   8:     public class buddha_class

   9:     {

  10:         public decimal GetTotalPrice()

  11:         {

  12:             decimal grandTotalPrice = 0, itemTotalPrice = 0, itemDiscountedTotalPrice = 0, itemTotalPriceCommodtity = 0;

  13:  

  14:             itemDiscountedTotalPrice = Convert.ToDecimal("100");

  15:             grandTotalPrice += itemDiscountedTotalPrice;

  16:  

  17:             return grandTotalPrice;

  18:         }

  19:  

  20:     }

  21: }

i open the dll using the ildasm and here is the output

for viewing the CIL just double click each method

Another free tool similar like ildasm …a great s/w where we can see the code in multiple languages

Selecting a single radio button inside a grid view

the below code will explain how to change your code for selecting a single radio button inside a grid view.

by default we can select multiple radio buttons inside a grid view.to make it a single selection we need to add a script..

below code explain that

  1 <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="CategoryID" DataMember="DefaultView" DataSourceID="SqlDataSource1"> 
  2 <Columns> 
  3 <asp:TemplateField> 
  4 <ItemTemplate> 
  5 <input type="radio" runat="server" id="rdOption" onclick="SelectOne(this,'GridView1')"  VALUE="rdo" /> 
  6 </ItemTemplate> 
  7 <HeaderStyle CssClass="Head" /> 
  8 <ItemStyle CssClass="Item" />
  9 </asp:TemplateField> 
 10
 11 <asp:BoundField DataField="CategoryID" HeaderText="CategoryID" InsertVisible="False" ReadOnly="True" SortExpression="CategoryID" > 
 12 <HeaderStyle CssClass="Head" /> 
 13 <ItemStyle CssClass="Item" /> 
 14 </asp:BoundField> 
 15
 16 <asp:BoundField DataField="CategoryName" HeaderText="CategoryName" SortExpression="CategoryName" > 
 17 <ItemStyle CssClass="Item" /> 
 18 <HeaderStyle CssClass="Head" /> 
 19 </asp:BoundField> 
 20 </Columns> 
 21 </asp:GridView>

add the following javascript

  1 <script language="javascript"> 
  2
  3 function SelectOne(rdo,gridName) 
  4 { 
  5    all=document.getElementsByTagName("input"); 
  6    for(i=0;i<all.length;i++) 
  7    { 
  8      if(all[i].type=="radio") 
  9      { 
 10         var count=all[i].name.indexOf(gridName+'$ctl' ); 
 11         if(count!=-1) 
 12         { 
 13            all[i].checked=false; 
 14         } 
 15       } 
 16     } 
 17    rdo.checked=true; 
 18 } 
 19 </script>

the Script will be called in the on click event of the radio button in the grid

The Write Less, Do More, JavaScript Library..Jquery



jQuery is a fast, concise, JavaScript Library that simplifies how you traverse HTML documents, handle events, perform animations, and add Ajax interactions to your web pages. jQuery is designed to change the way that you write JavaScript.

What jQuery Does

The jQuery library provides a general-purpose abstraction layer for common web scripting, and is therefore useful in almost every scripting situation. Its extensible nature means that we could never cover all possible uses and functions in a single book, as plug-ins are constantly being developed to add new abilities.

The core features, though, address the following needs:

1.Access parts of a page.

2.Modify the appearance of a page.

3.Alter the content of a page.

4.Respond to a user's interaction with a page.

5.Add animation to a page

6.Retrieve information from a server without refreshing a page.
(AJAX)

7.Simplify common JavaScript tasks.

            int startIndex = strInput.ToUpper().IndexOf("<" + key.ToUpper() + ">");

            int endIndex = strInput.ToUpper().IndexOf("</" + key.ToUpper() + ">");

            if(startIndex != -1 && endIndex != -1)

            {

                returnValue = strInput.Substring(startIndex + (key.Length + 2), endIndex - (startIndex + (key.Length + 2))).ToString();
            }

            return returnValue;

        }

 

string str = "<from>jeebu@abc.com</from>";

MessageBox.Show(ParseHtml(str ,"from"));

will return jeebu@abc.com
