什么时候该在我自己写的过程后面加上(Sender:TObject)呢?比如下面的代码,我加上后就报“参数出错”procedure TForm3.EmailIni;//加上(Sender:TObject)就出错beginif FileExists(extractfilepath(application.exename)+'person.ini') then begin speedbutton2.Visible :=false end else speedbutton2.Visible :=true
speedbutton3.Visible :=true;end;什么道理呢?
speedbutton3.Visible :=true;end;什么道理呢?
