Hi,
My client has a product database od around 20000 items. And it is
updated every few days when he gets a catalog from the supplier.
It's supposed to work like this: if there already is a product in the
database with that ID (primary key), just UPDATE the price, and if
there is no product with that ID it should do an INSERT for that item.
Now I've tried it in several ways and I can't seem to get it to execute

My program can, when directed, check a floppy for updates, verify the MD5
sums from another source, then copy the new Java classes to its own
directory tree. Once it does this, I'd like to restart the program so the
changes take effect.
What's the best way to do this?
I figure if I call the program's main class, it will run, but then I'll have
2 instances (the original and the one that's upgraded) running -- plus I'm
not sure if the...

I started writing this up as a guide for some people who were looking for
general tips on how to do things the 'right way' with Javascript. Their code
was littered with document.all and eval, for example, and I wanted to create
a practical list of best practices that they could easily put to use.
The above URL is version 1.0 (draft) that resulted. IMO, it is not a
replacement for the FAQ,...

I've had a user delete one of the client records, I do have a version of
the DB with all records intact before the deletion occured.
Whats the best approach to getting all the related records in each of
the tables? I have about 12 tables to put data back into and multiple
records for each. Would I need to make an append or update query for each
table?

Various versions of my app have been in use for the last 5 years or so
(in Access 97, 2K and XP editions). To upgrade the back end for people
I have to add fields to some tables, some new indexes, and a few
tables.
I have been looking at the dbUpgrader demo (the ActiveX device), but
have not been able to get it to work. Before I spend a lot of time on
this I was wondering if anyone had any suggestions on whether this is
worthwhile or if...

I'd like to hear your thoughts on best methods for populating drop down list
controls. I have states and countries drop down lists that don't change
often, so naturally I "hard code" them in the aspx page. But the problem is
these tend to really slow the development -- it takes up to 15 seconds for
the page to come up in VS.NET design environment, so I'm thinking about
taking these out and populating the controls dynamically using the...

Hello,
I am trying to use vs.net 2005 to migrate a project originally in vs.net
2003. I started with creation of a "web site", and then created folders for
each component of the site.
I read somewhere that each folder under the "web site" is compiled in
separate assembly. I however, did not find that the "web site" creation in
vs.net 2005 created any AssemblyInfo.cs file.

Hi guys,
Basically i have been developing in dotnet for a couple of years but
ive had a few issues in regards to error handling.

i have an output parameter which tells me whether the SP select is
successful or not. If i get a error code passed back then i throw an

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.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
