Eample of QueryString in ASP.NET

By Jacob

Introduction

If we want to pass control or variable value from one form to another form then we can use QueryString . There are many options available to pass queryString , these are.

In Hyperlink:

    <a href=”~/Default.aspx?id=10&name=Jacob”>QueryString Example</a>

In Response.Redirect method :

 Response.Redirect(“~/Default.aspx?id=10&name=Jacob”);

If we want to get queryString Parameter valuefrom url then we should use Request.QueryString  Object.
Label1.Text=Request.QueryString[“querystring parameter”].ToString();

Lets take an simple example to pass textbox value from one form to another form using QueryString.




<%@ Page Language="C#" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<script runat="server">

    protected void Button1_Click(object sender, EventArgs e)
    {
        Response.Redirect("~/Default2.aspx?name=" + TextBox1.Text);
    }

    protected void Page_Load(object sender, EventArgs e)
    {
        if (Page.Request.QueryString["name"] != null)
        {
            Label1.Text = "name of the querystring parameter is " + Page.Request.QueryString["name"];
        }
    }
</script>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        Enter Name :
        <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox><br />
        <asp:Button ID="Button1" runat="server" Text="QueryString" OnClick="Button1_Click" /><br />
        <asp:Label ID="Label1" runat="server" Text=""></asp:Label>
    </div>
    </form>
</body>

</html>

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

Print the asp.net webpage using button
