blob's, c++, and sdac

I realize that this is a long shot, but has anyone used the SDAC component for borland c++ builder to insert blob's into a database. I am trying to figure out how to go about this. I believe that I am able to retrieve blobs from the db, but I haven't been able to test it because I can't insert them in the db. Do I need to create a TBlobField, or can I just use a TImage and then convert it when inserting into the db. This is how I am retrieving the data.

DB->MSQuery->GetBlob("JPEGImage")->SaveToFile("c:\\temp.jpeg");

I haven't been able to find a TPutBlob or something similar. SDAC is a control from core labs that stands for SQL Data Access Component. Thanks for any help you can give,

Ben
