void __fastcall TIproveEditConnection::DeConnectionClick(TObject *Sender)
{
        TListItem *Item = ConnectStatusListView->Selected;
        TItemStates selected = TItemStates() << isSelected;
        while (Item) {
                char temp[MAX_SIZE];
                sprintf( temp, "%s\n",Item->Caption);
                IproveNormalMessage(temp);  // 메세지 찍는 함수...
                for( int i = 0; i < Item->SubItems->Count; i++ ) {
                        sprintf( temp, "%s\n",Item->SubItems->Strings[i].c_str());
                        IproveNormalMessage(temp);                       
                }
                Item = ConnectStatusListView->GetNextItem(Item, sdAll, selected);

        }
}

위와 같이 해결했습니다....

알고보니.. 쉽네요 ^^
