Paradox 10 General Protection 1

[SercoSteve]

We have just installed Paradox 10 on our network. In Paradox 10 Runtime selecting print from the File Menu causes a General Protection Error on our WINNT machines. Win95 and Win98 machines are fine.

Anybody got any ideas.

Regards

Steve,

In general , GPF's are notoriously difficult to debug because they contain little direct information regarding the underlying problem.

However, there are a few things I've seen cause GPF errors:

1. Forms and reports that have invalid stylesheets associated with them. While you may not use sytlesheets directly, Paradox always saves stylesheet references with forms and reports. Thus, we need to verify that stylesheets are appropriately defined. See

http://techtricks.com/paradox/styleprobs.php

for more information and related articles.

2. Forms and reports that've been saved with active filters or ranges. To check this, you need to open each document in a design window, choose Format | Filter, clear any criteria that appear in the filter fields, and then save the document. Once you've done this, the problems should disappear.

3. Running Paradox on a version of Windows based on Windows NT (such as Win2K, XP, 2003 and so on) without disabling certain configuarion defaults. See

http://www.thedbcommunity.com/faq/29.htm

and

http://bdesupport.com/stability.htm

for details.

4. Not attaching your printers to LPT ports. Recent versions of Windows let you share printers using UNC paths. In certain cases, this causes problems for Paradox. You should, instead, attach network printers to local LPT ports and print to those local ports.

Hope this helps...

The probloem seems related to your number 4.

We have sort of isolated the problem to the network printer name length, anything over 25 chars gives us the the GP.

Thanks again
