Hello
  I an trying to store a binary data string in an Access database, I can see 
you need a OLE field but in not sure how to get C++ Builder to write data to 
this field. I normally use FieldByName->AsString for text but this does not 
work for binary data. Can anyone help or point me in the right direction

Thanks

Cast to TBlobField and use TBlobField::LoadFromStream() and 
TBlobStream::SaveToStream().
