ADO添加图片的错误！！！！！！！！！

[火鸟33]

代码：
TBlobField * pField=(TBlobField *)ClientModule->PictureDataSet1-〉FieldByName("Picture");
TBlobStream * pmem=new TBlobStream(pField,bmWrite);
pmem->Seek(0,soFromBeginning);
Graphics::TBitmap * pBitmap=new Graphics::TBitmap();
pBitmap->Assign(Image1->Picture->Graphic);
pBitmap->SaveToStream(pmem);
delete pBitmap;
delete pmem;

错误：
[Linker Error] Unresolved external '__fastcall Dbtables::TBlobStream::~TBlobStream()' referenced from D:\网站工程\工程\CLIENT\CCLIENT.OBJ
[Linker Error] Unresolved external 'Dbtables::TBlobStream::' referenced from D:\网站工程\工程\CLIENT\CCLIENT.OBJ
[Linker Error] Unresolved external '__fastcall Dbtables::TBlobStream::TBlobStream(Db::TBlobField *, Db::TBlobStreamMode)' referenced from D:\网站工程\工程\CLIENT\CCLIENT.OBJ

你应该用TStream来存取ADO的Blob字段，你可以仔细看一看CB的帮助

斑竹写的：
//读
TBlobField * pField=(TBlobField *)pQuery->FieldByName("Image");
TBlobStream * pmem=new TBlobStream(pField,bmRead);
pmem->Seek(0,soFromBeginning);
Graphics::TBitmap * pBitmap=new Graphics::TBitmap();
pBitmap->LoadFromStream(pmem);
Image1->Picture->Assign(pBitmap);
delete pBitmap;
delete pmem;
//写
TBlobField * pField=(TBlobField *)pQuery->FieldByName("Image");
TBlobStream * pmem=new TBlobStream(pField,bmWrite);
pmem->Seek(0,soFromBeginning);
Graphics::TBitmap * pBitmap=new Graphics::TBitmap();
pBitmap->Assign(Image1->Picture->Graphic);
pBitmap->SaveToStream(pmem);
delete pBitmap;
delete pmem;

为什么出现这错误？

[火鸟33]

我就是用的这段代码，不行！

真鬼，我放了个TTable 就管用了
删掉还管用？？
把头文件删除还是好的？？
