{Important: Methods and Properties Of Objects in Visual Components CAN Only Be? Used in a Method Called Using Synchronize, for Example,
????? synchronize (UpdateCaption);
? And UpdateCaption Could Look Like,
??? procedure thread.updatecaption; ??? begin ????? form1.caption: = 'updated in a thread'; ??? end;} {thread}
