delphi中图片保存后再使DBIMAGE显示总提示‘BITMAP IMAGE IS NOT VOLID'

[sumh88]

各位大佬：
小弟新手，编个条形打开小程序，先在IMAGE1中产生条形码，再存入个文件取名’TEST.BMP',然后,再读入IMAGE2中(因不知在IMAGE1中产生的条形码图形是否是图像)，再保存在SQL中。
再次通过DBIMAGE控件显示，可是总是提示‘BITMAP IMAGE IS NOT VOLID'信息，不知为何，请各位大佬指教，万分感谢。
另外数据库是SQL2000，保存图像的字段名为TS，值为IMAGE

万分感谢二位大佬

BMP的还用TJPEGImage干麻.

ms:= TMemoryStream.Create;
Image2.Graphic.SaveToStream(ms); // 直接IMAGE2
ms.Position:= 0;
ADOQ1.Edit;
TBlobField(ADOQ1.Fields[0]).LoadFromStream(ms);
ADOQ1.Post;
ms.Free;
