Can someone tell me exactly how i can use this code.

TBlobField(Table.FieldByName('Content')).SaveToStream(TOleStream.Creat
e(DataStream));

TBlobField(Table1->FieldByName("Content")).SaveToStream(TOleStream->Cr
eate(DataStream));
[C++ Error] Unit2.cpp(116): E2108 Improper use of typedef 'TOleStream'

And this other one

__int64 Dummy = 0;
_di_IStream DataStream;

DataStream->Seek(0, STREAM_SEEK_SET, (ULARGE_INTEGER*)&Dummy);
[C++ Error] Unit2.cpp(117): E2034 Cannot convert 'int' to
'_LARGE_INTEGER'


Thanks a lot.

Here you go:

    ((TBlobField*)Table->FieldByName("Content"))->SaveToStream(new
TOleStream(DataStream));

LARGE_INTEGER is a structure, but you're trying to pass a single numeric
value instead.  The first parameter of Seek() needs to be like this instead:

    LARGE_INTEGER li
    li.QuadPart = 0;

    DataStream->Seek(li, ...);
