[AccessD] Scanning into mdb

Thanks Jim.  

Did you use the Kodak Imaging control to call the scanner?

Hi Jim:

In the application that I wrote the scanner program was called from the
Access app and therefore I could hard code the profile, naming and save-path
of the scanned images... similar to the feature of a full-licensed version
of WinZip. I did not have to encrypt the images (jpg) as the application
also moved the graphics to a secure centralized directory on the server,
after the new image was saved locally.

HTH
Jim

Thanks Jim and Jim who replied from Jim who posted!

So I gather I should save to files or encrypt the BLOBs.  WinZip has some
automation tools.  I wonder if I should see if I can zip the images and
password protect the zip file?  Hmm.

I asked about TWAIN support because I thought the Kodak image control was
removed from XP.  Doesn't that have something to do with imaging in Access?

One last question.  If I can scan the images can I automate the saving and
naming of the files or will the user have to do that?

Thanks again

Jim DeMarco

<<1. Did you scan into BLOB data fields or store in graphic image format?
I'd prefer to use BLOBs as we'll be scanning HIPAA protected personal health
information and I don't want files on the laptops that anyone can access.
If you used BLOBs how did you tell the scanner where to store the data?>>

  Definitely want to go with a file on disk in some type of graphic format.
If you let Access handle the insert, it places an OLE wrapper around the
object which can double the storage required.

  If you really want, you can save the image to disk first, then pull into a
BLOB on your own.  That will avoid the bloating issue.  However you'll need
to export the BLOB back out to be able to do anything with it.

  In your case, this might be a good fit, as Access on it's own is easily
crackable and I'm sure would not meet HIPPA standards. When your write/read
the BLOB, you can use some form of encryption on it.  Then distribute the
app as a MDE so your code can't be looked at.

<<2. Are BLOBs an issue in A97?  The users fear data corruption.  There will
be 1-200 medical charts scanned in per day then the data is replicated back
to our main db here.>>

  I've never found memo or OLE fields to be an issue.  Others have.  A lot I
think depends on the type of environment the app runs in and the fact that
many people try to make Access do things it was never meant to do (like run
over a WAN).

<<3. We will be moving to A2K3 within the next few months and probably Win
XP (from 2000).  Will twain support in A2K3 and WinXP be an issue?  If so
what can I do in our A97 app now that will prevent issues when we upgrade
the mdb?  Are BLOBs an issue in A2K3?>>

  I can't think of any specific issues; all the drivers will still be 32 bit
and twain support has changed little if any over the years.

HTH,
Jim.

List,

I see in the archives that some of you have implemented scanning of images
into your Access systems.  I'm being asked to add some imaging to an
existing A97 app that runs in the field on laptops and I've got some
questions.

1. Did you scan into BLOB data fields or store in graphic image format?  I'd
prefer to use BLOBs as we'll be scanning HIPAA protected personal health
information and I don't want files on the laptops that anyone can access.
If you used BLOBs how did you tell the scanner where to store the data?

2. Are BLOBs an issue in A97?  The users fear data corruption.  There will
be 1-200 medical charts scanned in per day then the data is replicated back
to our main db here.

3. We will be moving to A2K3 within the next few months and probably Win XP
(from 2000).  Will twain support in A2K3 and WinXP be an issue?  If so what
can I do in our A97 app now that will prevent issues when we upgrade the
mdb?  Are BLOBs an issue in A2K3?

This app is for data collection only and if we do store as BLOB we will
convert to graphic image for storage and retrieval here so the images would
not sit in the mdb for long.

TIA
