(Form2.Table1.FieldByName('report') as TBlobField).SaveToStream(OleStream);
OleStream.Position := 0;
OleContainer1.LoadFromStream(OleStream);
(Form3.Table1.FieldByName('report') as TBlobField).SaveToStream(OleStream);
//OleStream.Position := 1;
OleContainer1.LoadFromStream(OleStream);//这一步出错
OleContainer1.SaveAsDocument('d:/cc.doc');
请问这样的程序应该怎样写????非常感谢!!!!!!!!

你的问题很怪，难道原始文件在存到数据库的时候是分段存储的吗?
如果是分段存储，要先合并，然后在导入流中

各个BLOB字段,是各个阶段的报告,我要将他们和为一个文档.

Form2.Table1.FieldByName('report') as TBlobField).SaveToStream(OleStream);
P:=OleStream.Position;
OleStream.Position := 0;
OleContainer1.LoadFromStream(OleStream);
(Form3.Table1.FieldByName('report') as TBlobField).SaveToStream(OleStream);
OleStream.Position := p;
OleContainer2.LoadFromStream(OleStream);//这一步出错

OleContainer1.SaveAsDocument('d:/cc.doc');
如果,将程序改成这样stream中存入了两段blob字段,但是一个ole只能取出一个blob字段

每个blob字段有一个流结束标志，你不能直接就合并得！
