How to retrieve images from database table in ASP.NET

By Jacob
Database is a storage system, through which we can store data permanently into the secondary storage device. Similar to programming languages, database also take some data types for categorize data. like int, Text, DateTime etc. Now, we will discussed on image. In this example we will retrieve images from database. First we store images into database, actually images is not stored directly, so for that path of the images is stored into the database. Now, bind the GridView with the image field.  

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default2.aspx.cs" Inherits="Default2" %>

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
 
    </div>
        <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="Id" DataSourceID="SqlDataSource1" Width="280px">
            <Columns>
                <asp:BoundField DataField="Id" HeaderText="Id" InsertVisible="False" ReadOnly="True" SortExpression="Id" />
                <asp:BoundField DataField="name" HeaderText="name" SortExpression="name" />
                <asp:ImageField DataImageUrlField="imagepath" HeaderText="Image">
                    <ControlStyle Height="200px" Width="200px" />
                </asp:ImageField>
            </Columns>
        </asp:GridView>
        <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString %>" SelectCommand="SELECT * FROM [imagetable]"></asp:SqlDataSource>
    </form>

Polynomial representation using Linked List for Data Structure in 'C'

By
Polynomial representation using Linked List The linked list can be used to represent a polynomial of any degree. Simply the information field is changed according to the number of variables used in the polynomial. If a single variable is used in the polynomial the information field of the node contains two parts: one for coefficient of variable and the other for degree of variable. Let us consider an example to represent a polynomial using linked list as follows: Polynomial:      3x 3 -4x 2 +2x-9 Linked List: In the above linked list, the external pointer ‘ROOT’ point to the first node of the linked list. The first node of the linked list contains the information about the variable with the highest degree. The first node points to the next node with next lowest degree of the variable. Representation of a polynomial using the linked list is beneficial when the operations on the polynomial like addition and subtractions are performed. The resulting polynomial can also
