Hello there,

From a VB.NET program that generates CSV-files from a SQL2000-database, I get the following error:

13-4-2006 9:03:03

The error occurs totally unpredictable (it can occur every run for 15 runs and then 15 runs can work OK?!?!) and I can't explain the reason it occurs.

Does anyone here have a clue??

Greetings...
