DBArchiveReader question

rbuser

Is it still required that I save the report to a file before I load it into
a db? Looking at example 155, that's the way it is done. I would prefer
to be able to save straight from a report to the db, which is what I thought
it did, and is the reason I upgraded to 7.

Any help is appreciated.

Hi Bobby,

Sorry, this is a little confusing. We have a way to read Report Archives
from a database but we do not have a built in way to write them. This is on
our wish list for future enhancements. As for now, you will need to write
to file and stream it to a BLOB field using the method described below (same
as demo 155).

---------------------------------------------------
Tech Tip: Loading an Archive File to a Blob
(or memory stream)
---------------------------------------------------

You can easily write a routine to take a .RAF file and
load it into a blob field or a TMemoryStream:

myFileStream := TFileStream.Create('myArhcive.RAF', fmOpenRead);

myFileStream.Position := 0;
myBlobField.LoadFromStream(myFileStream);

myFileStream.Free;


OR

myMemoryStream := TMemoryStream.Create;

{note: passing 0 as the second parameter will copy the entire stream}
myMemoryStream.CopyFrom(myFileStream, 0);

myMemoryStream.Free;
