Subject: TBlobStream

Can someone explain to me why this doesn't seem to work...
I dont think its saving to the DB and then when ready its empty. Please advise. (Note only snippets of code)

Creating picture works.................
Picture: TDibGraphic;
Picture := TDibGraphic.Create;
Picture := NewDibGraphic(OpenDialog.Filename);

Storing to DB doesn't..................
BlobStream: TStream;
BlobStream := CreateBlobStream(TBlobField(FieldByName(CPicture)), bmWrite);

Reading doesn't......................
BlobStream := CreateBlobStream(TBlobField(FieldByName(CPicture)), bmRead);

Please advise, when I try to save to DB, it says its empty and whenI try to read its empty. I check Picture before saving to DB its not empty, I think... Anythink I'm doing wrong????????
