How to get raw byte array or Binary{} from a memo-field?

DBFCDX (with FPT support). How to get/put memo-field as a raw value - BYTE[] (if possible without first 8 bytes of a header) ? BlobGet, as far as I see, returns a string, which is grinded with encoding.
regards,
Serggio

Hi Serggio,
please look at the function FieldGetBytes() in the online help.
AFAIK the DBServer has no suchg method.

Hi Serggio,
sorry, I was wrong: since 2.6 there is such a method in the RDD classes.
There is a method FieldPutBytes() and FieldGetBytes():

Hi Wolfgang,
I must admit I had not realized Robert has already added this also to the SDK, I was about to log a feature request to add it, but then I saw your reply

Hi Chris,
I know I have asked for this method because I need it for several migrations, but probably I had read the whatsnew document to fast to realize that this is now implemented.
As you probably know, I'm storing many different things in DBF fields - from compressed bitmaps to crypted content, and I need to retrieve a byte array for this.

Thanks a lot for this suggestion!
Haven't tried it yet, but I'm sure it will work.
