Title: Download from Blob
Post by: rjolda on April 14, 2010, 05:09:51 AM

Hi,
How does the Web server know that a Memory String has been extracted from a BLOB and how does it know to serve the String instead of an actual file?
Thanks,
Ron Jolda

Hi Ron,
ALAIK, you need to BlobToFIle() and serve the file.

no, you certainly do not need to save the blob to a file, and then serve the file.

Ron - I presume you've examined example 40?

In it there is code in the WebHandler procedure, in the _SendFile method.
This code is before the parent call, and you'll notice ends with a RETURN if the requested "file" is found as a Blob.

You'll also notice that it makes a call to _SendMemory, sending the contents of the Blob (which was temporarily stored in sendString).

Cheers
Bruce
