你好 ~我现在自学网络开发,碰到多线程问题,然后,就来学习多线程程序的开发
   但是简单的我懂  
   显示进度条线程部分:
                    unit WaitThread;
                    interface
                     use
                        Class,Windows,ComCtrls;
                       trpe
                       TWaitThread=class(TTread)
                         private
                     FDelayMS:Cardinal;{
                     FBar:TProgressBar;   请问高手这５句是不是　　　　　　　　　　　　　　　　　FNewBarPos:Integer;　　　固定的必须设置这些属性
                     procedure INiteBar;　　还是有别的什么原因
                     procedure UpdateBar;
                     procedure KillBar;    }
                protected
                   procedure Execute; override;
