同花顺盘后日线数据读取

很长时间没有用D7,但是小应用原生代码还是要转回到D7.这两天在看同花顺和通达信，下载后的盘后数据下载想直接导入EXCEL。参考网上的同花顺数据格式介绍，下面的代码用于在TMEMO控件中显示文件头和文件内容。长时间不用D7,生殊处请见谅。 procedure TForm1.btOpenClick(Sender: TObject); var TM:TMemoryStream; FHard:TDayRec; PColDef:PByte; s,i:integer; tmp:Dword; begin if OpenDialog1.Execute then begin FName:=OpenDialog1.FileName; tm:=TMemorystream.Create; try tm.LoadFromFile(FName); tm.Read(FHard,sizeof(TDayRec)); Memo1.Lines.Add(format('数据记录总数:%x / %d ',[fhard.rows,fhard.rows])); memo1.Lines.add(for mat('数据记录内容开始地址:%x / %d ',[Fhard.StartAdd,Fhard.StartAdd])); memo1.lines.add(format('每条记录的长度:%x / %d ',[FHard.RecordLenght,FHard.RecordLenght])); memo1.lines.add(format('每个记录的列数:%x / %d ',[Fhard.ColNum,Fhard.ColNum])); fhard.StartAdd:=sizeof(TDayRec)+fHard.ColNum*4; memo1.Lines.add(format('数据记录内容真实开始地址:%x / %d ',[Fhard.StartAdd,Fhard.StartAdd])); s:=FHard.ColNum*sizeof(TRecordDefine); GetMem(PColDef,s);; try tm.Read(PColDef^,s); for i:=0 to Fhard.ColNum-1 do begin tmp:=PDWordArray(PcolDef)[i]; //tmp:=PDword(integer(pcoldef)+i*4)^; memo1.Lines.add(format('列 %d: %x , 列长度:%x',[i,tmp,TColdef(tmp).ColLength])); end; finally freemem(PColDef); end; finally tm.Free; end; end; end;
