Hi.
I have to design new API, which some of them have to return a string.
I have mixed feelings about the various strategies I can choose :
1. API(char *s, long *size)
=> the client gives a string pointer and its size; If the server has
to return a longer string, it fails, and the client calls back with a
longer string.

Hi there,
I'm in 3-tier project and I'm thinking about having Try / Catch
statements in each method, just in case you know!
If the case is that I don't have a special treatment for the error in
some method I would Cath the error and Re-Throw it!
The question is: what are the issues of this approach? Would I have
performance problems cus of my catches? What does MS recommends in such a
situation??

Many of our apps are in production and they do not have proper error logging
in them - unhandled errors are seen by the users in the form of error
messages and stack traces. I know how to make apps handle their errors
(global.asax.cs "application_error" event, web.config "customErrors"
section, etc). But can I do this without having to visit each app? Can
this be done at the machine level? I'm looking for a kind of machine-level...

Hi all,
I have an application which needs to manage the status on a server with 96
phone line ports. Each port is an indepedent process and reports status
codes independently.
Currently I have 1 thread per port monitoring the status... this is fine
for low volumes (i.e. when I only have 20 - 40 ports enabled) but once I
enable all 96, it seems that some messages are being backlogged. I *think*

With VB.NET 2005, and a Windows Form, running on a dual CPU box, I need to
take a recordset (e.g. 100,000 records) and spawn a thread to handle an
internet XML transaction routine for each of the records. This is a nice
use of threading because those internet requests are going against 3rd party
servers that often have 1 second latency problems and so handling them with
multiple threads is the fastest way to get through all the records in...

I'm writing a TCP/IP server app that will have many simultaneous
connections. The main thread listens for new connections and starts a
thread to handle each requested connection. These are short lived
threads that get a request and return a reply and end.
Can the main thread tell me how many connection threads are currently
running at any given time? I'd like to have a label on the main form to
show how many connections the server is...

A wizard? A formView?
I wanna capture about a dozen fields of info, then show a "is this
information correct" page, then allow edit or save.
Which is the best way?
I was thinking I could hide the formview and display its information in
labels when it came time to ask "is this info correct"?

I'm writing something in JS using the latest OO and JSON
and I'm looking for a bit of guidance. I'm going to have this
large object which has many top-level properties and some
top-level functions. That part I have no problem with, I'll
define it in JSON style (my prototype is working just fine).
What I'll also have though, is some arrays at the top level.
These arrays will contain n number of sub-objects. Each
of these sub-objects will...

Hi all,
I am a Python novice, and I have run into a problem in a project I am
working on, which boils down to identifying the patterns in a sequence
of integers, for example

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.

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
