DBWEB: Updates Not Working Using Default dbWeb Documents

• Microsoft dbWeb, version 1.1

SYMPTOMS

When using the dbWeb default HTML update document, if you click the Submit Update button, a blank screen appears on your browser and no success or failure message is displayed for the update. When you look in the underlying table for the update, you notice that the data has not been changed.

CAUSE

The new caching functionality built into dbWeb version 1.1 caused the updates not to work properly.

RESOLUTION

There are two ways to work around this problem:

1. Create a custom DBX to perform the update.



2. Download dbWeb version 1.1a from the Microsoft dbWeb internet site at the following Web address:

   http://www.microsoft.com/intdev/dbweb

STATUS

Microsoft has confirmed this to be a problem in Microsoft dbWeb version 1.1. This problem does not occur in dbWeb versions 1.0 or 1.1a.
