I have developed what amounts to a fancy shopping cart wizard for a
scientific instrument using VB.NET. We are having some disturbing
phenomena relating to dropdown controls.
On my system and other XP based systems I can repopulate the dropdowns
just fine, to reflect different system configurations. However one of
our engineers is runnign Windows 2000 and he has noticed that the
dropdowns are showing several blank lines. They are behaving properly
within the program but he is "selecting blindly" from these lists as
they are blank.
As my code reacts to the selectedIndex of the dropdown, not the
selected item's text, I don't really know whether this is a display
issue only, or a display and data issue. None of the other users have
observed this bug but we are intending to distribute this program to a
broad audience and I'd love to hear if anyone else has seen anything
like this before.

Dave,
Any chance the user with the problem is running McAfee VirusScan Enterprise
8.0i?
If so, this is a known problem and there is a fix on McAfee's web site.

Maybe the problem is caused by an unpatched virus scanner. These symptoms
are typically caused by a McAfee VirusScan problem that NAI is aware of and
that can be fixed by installing a patch:
Patch 5 for McAfee VirusScan Enterprise 8.0i

Hi there.
I am having an intrigueing problem.
I have a query which left joins another query to itself twice. The
original query is derived from a linked table in SQLServer 2000.
When I run it on my pc It runs fine. However for other users in the

Hi Freinds,
We are facing a very strange problem. Our system consists of UNIX batches which call the PLSQL procedures to execute the validations on the database.

The problem is that one of the procedure is working very differently. Some times when we execute the batch it gives the error on one record, and if we...

Hi,
I have some code which parses a text file and creates objects based on
what is in the text file. The code works just fine on Windows, but when
I compile it using XCode on OS X the parsing goes all wrong. Is there
some known differences with file handling on OS X?
My code is quite long, but one of the defect parts looks like this

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
