在BCB中数组的妙用和纪录和改变控件的状态

如果能巧妙地运用数组会给我们带来很多方便;以下是我的一些用法，还觉得自己每掌握它的精髓；希望大家多多指点；（现丑了）

void ) __declspec(dllexport) myList::ReadList(AnsiString TS)
{//读出ini文件的数据
   System::AnsiString LabPath=ExtractFilePath(".\\");
   TIniFile *LabIni=new TIniFile(LabPath+"LabIni.ini");

   Form2->AddList();
   for(int i=0;i<Form2->LabelList->Count;i++)
    {
       TLabel *Lab;
       Lab=(TLabel *)Form2->LabelList->Items[i];
       Lab->Left=LabIni->ReadInteger(TS,"Left"+IntToStr(i), Lab->Left);
       Lab->Top=LabIni->ReadInteger(TS,"Top"+IntToStr(i),Lab->Top);
    }
}
file://----------------------------------------------------------------------------

void myList::WriteList(AnsiString TS)
{//写入文件
   System::AnsiString LabPath=ExtractFilePath(".\\");
   TIniFile *LabIni=new TIniFile(LabPath+"LabIni.ini");
   Form2->AddList();
   for(int i=0;i<Form2->LabelList->Count;i++)
    {
       TLabel *Lab;
       Lab=(TLabel *)Form2->LabelList->Items[i];
       LabIni->WriteInteger(TS,"Left"+IntToStr(i), Lab->Left);
       LabIni->WriteInteger(TS,"Top"+IntToStr(i),Lab->Top);
    }
}

file://------------------------------------------------------------------------------------------

  System::AnsiString LabPath=ExtractFilePath(".\\");
   TIniFile *LabIni=new TIniFile(LabPath+"LabIni.ini"); 

  TList *LabelList;
   LabelList=new TList;
   LabelList->Add(Label1);
   LabelList->Add(Label2);
   LabelList->Add(Label3);
   LabelList->Add(Label4);
   LabelList->Add(Label5);
   LabelList->Add(Label6);
   LabelList->Add(Label7);
   LabelList->Add(Label8);
   LabelList->Add(Label9);
   LabelList->Add(Label10);
   LabelList->Add(Label11);
   LabelList->Add(Label12);
   LabelList->Add(Label13);
   LabelList->Add(Label14);
   LabelList->Add(Label15);
