Save archive to a database

rbuser

Hi.

I've noticed that ReportBuilder comes with TppDBArchiveReader, wich reads
an archived report from a table. But I can't figure out how to store the
archive in the database in the first place. I might try to generate the
archivefile first, and then store the file in a table. But I guess there
is an easier method?

Thanks in advance,
Arild Bøifot

Hi Arild,

---------------------------------------------------
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;
