how to use thread

Remember Your UI is the main thread an all other threads are the child threads

so to use simple threading In your application

You can do this

Public void SendMail()
{
//Mail sending code
}


and to call this Thread

Thread thsendmail=  new Thread(SendMail)
thsendmail.Start()


another approach is to use the delegates in this You can define the delegates

//Declare the Delegate
Public delegate void sendMail(EmailObject );
 

To Call this delegate You can use the

sendMail Objdelegatesendmail= new sendMail()
IAsynchResult ia= Objdelegatesendmail.BeginInvoke(EmailObject,null,null );

Here First null is the CallBack Method if u need somethings
