Asp.Net Post for Get Home screen tweets from twitter using API and store into SQL Server Database

Get Home screen tweets from twitter using API and store into SQL Server Database

My first Asp.Net article  for the twitter tweets related to display latest less than 200 tweet for home screen in ASP.NET page and store in the database table.

Introduction

i search a lots of things related twitter tweets,i found lots of solution on internet using this information and i devlop a one Asp.net application for Display latest tweets on my page and store the tweets in my sql server database and use Visual studio 2010 withe .Net Framework 4.0

Background

First of sign in to twitter using this link https://apps.twitter.com/ and follow the step and Get the
"ConsumerKey"
"ConsumerSecret"
"TokenKey"
"TokenSecretkey"
After get all the twitter key the create a database in MS SQL Server and create a table

code

first Design the Default.aspx page


<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
 
<!DOCTYPE html>
 
<html xmlns="http://www.w3.org/1999/xhtml">
<head id=Head1 runat="server">
    <title></title>
 
    <style type="text/css">
        #myTitle
        {
            color: Black ;
            font-weight :bolder ;
            font-style :normal ;
        }
        
        #myDiv
        {
            background-color: #FFFFFF;
        }
        
    </style>
 
</head>
<body>
    <form id="form1" runat="server">
    <div id="myDiv" runat="server">
     
    </div>
    </form>
</body>
</html>

now next set the key and connection string in Web.config file

<connectionStrings>
    <!--put your connection string here-->
    <add name="conString" connectionString="Data Source=ServerName/IP;Initial Catalog=dbname;Integrated Security=false;User Id=username;Password=password;Persist Security Info=true; Connect Timeout=1000;Max pool size=25"/>
  </connectionStrings>
  <appSettings>
    <add key="ConsumerKey" value="hMYnAWt4fkZuirxDKvsH2yXe"/> <!--"insert here...";-->
    <add key="ConsumerSecret" value="763lji0wK3hrjSgAdC4Jz2XyfIs4nOK4cOo1BHNsBnTvr2vGU"/><!--"insert here...";-->
    <add key="TokenKey" value="3171598760-1mfuPn7YpzXRqDnj3Jnm6dg7YkYdN9J8qw7rZ"/><!--"insert here...";-->
    <add key="TokenSecret" value="DPjzDM8zy4DUDwtvYSRI4QeCWY9b6AEvP74fySyRc"/><!--"insert here...";-->

  <add key="Twitterizer2.EnableStatisticsCollection" value="false"/>
  </appSettings>


Now write this code in Default.aspx.cs code file
