{   
string TwitterUserName = "twitasp";
string TwitterPassword = "mypassword";
string TwitterMessage = txtShout.Text;

if (TwitterUserName != string.Empty && TwitterPassword != string.Empty)
{
try
{

Twitter twitter = new Twitter(TwitterUserName,TwitterPassword);

string TwitterMsg = txtShout.Text;
if (txtShout.Text.Length > 120)
{
TwitterMsg = TwitterMsg.Substring(0, 130) + "... For more update logon to DailyFreeCode.com";
}
else
{
TwitterMsg = TwitterMsg + "... For more update logon to DailyFreeCode.com";
}
twitter.Status.Update(TwitterMsg);
lblTwitMsg.Text = "Your have shout successfully on http://twitter.com/" + TwitterUserName;
