将一个字符串映射为一个Delphi页面控件属性名（通过FindComponent和GetPropInfo找到这个控件指针）

uses   TypInfo;   

  function   TForm1.SetControlProp(ComStr,   value:   string):   boolean;
  var   ComName,   ComProp:   string;
          i:   integer;
      Loop:   Integer;
      PropInfo:   PPropInfo;
      cp:   TComponent;
  begin
      i   :=   Pos('.',   ComStr);
      if   i   >      then
      begin
          ComName   :=   copy(ComStr,   ,   i-);
          ComProp   :=   Copy(Comstr,   i+,   );
          cp   :=   FindComponent(ComName);
          PropInfo   :=   GetPropInfo(cp.ClassInfo,   ComProp);
          if   Assigned(PropInfo)   then
              SetStrProp(cp,   PropInfo,   value);
      end;
  end;   

  procedure   TForm1.Button3Click(Sender:   TObject);
  begin
    SetControlProp('button1.caption',   'test');   // 設置button1的caption   為   test
  end;
