<<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. -----Original Message----- From: accessd-bounces at databaseadvisors.com [mailto:accessd-bounces at databaseadvisors.com]On Behalf Of Jim DeMarco Sent: Thursday, December 29, 2005 10:58 AM To: AccessD (E-mail) Subject: [AccessD] Scanning into mdb 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.
