即ACCESS中有两个字段,一个是ID,一个是picture,能实现在一个界面中显示它的缩略图,用于展示。比如一次显示前五个记录中的图片,然后可以点翻页,接着显示其它的图片,达到遍历。程序中有流来读取ACCESS中的图片,格式为jpgfunction JpegStartsInBlob(PicField:TBlobField):integer;//找起始标记函数
var
  bs:TADOBlobStream;
  buffer:Word;
  hx:string;
begin
  Result:=-1;
  bs:=TADOBlobStream.Create(PicField,bmRead);
  try
    while(Result=-1) and (bs.Position+1<bs.Size) do
    begin
      bs.ReadBuffer(buffer,1);
      hx:=IntToHex(buffer,2);
      if hx='FF' then
      begin
        bs.ReadBuffer(buffer,1);
        hx:=IntToHex(buffer,2);
        if hx='D8' then Result:=bs.Position-2
        else if hx='FF' then
          bs.Position:=bs.Position-1;
      end;
    end;
  finally
    bs.Free
  end;
end;
procedure TForm1.Button1Click(Sender: TObject);//读取图片
var
  bs:TADOBlobStream;
  pic:TJpegImage;
begin
  bs:=TADOBlobStream.Create(AdoTable1Picture,bmRead);
  try
    bs.Seek(JpegStartsInBlob(AdoTable1Picture),soFromBeginning);
    pic:=TJpegImage.Create;
    try
      pic.LoadFromStream(bs);
      Image1.Picture.Graphic:=pic;
    finally
      pic.Free;
    end;
  finally
    BS.Free
  end;
end;
我想实现的是能够一次过在同一个界面中显示多个记录的图片,便于浏览,不知道有什么实现方法,或者相关组件呢?
谢谢各位了!
