Hi all -
I have a web application and I want to be able to do some basic error
handling. For example, here is one error I would like to catch and
display in a useful way for the user:
-----------------
Microsoft OLE DB Provider for ODBC Drivers error '80040e14'
UPDATE statement

Everyone knows that global variables get re-set in an mdb when an un-handled
error is encountered, but it seems that this also happens when the variable
is defined as private at form-level.
So if "global variables get re-set" doesn't tell the whole story, then what
does?
***please note***
I'm not looking for a solution - I'm looking for a more detailed description
of what happens when an un-handled error occurs - possibly with help file...

I need help in implementing proper error handling.
I am trying to upload a file based on the sample code below. The code works
well except if the file selected is too big.
I do know about the maxRequestLength parameter of the <httpRuntime> section
and that works as expected. What I want is to enforce a max file size but
haven't been able to trap the error thrown when the file is too large and
that's where I could use some help.

I'm confused about structured error handling. The following piece of
code is a simplification of a class library I'm working on. It works,
and it does what I want, but I'm still not convinced that I have been
doing it right. I think I overdo it. Please have a look:

using System.IO;

I am considering general error handling routines and have written a sample
function to look up an ID in a table. The function returns True if it can
find the ID and create a recordset based on that ID, otherwise it returns
false.
**I am not looking for comments on the usefulness of this function - it is
only to demonstrate error handling**
There are three versions of this code. David Fenton says under the earlier

Hi
How do I tell the user he has tried to upload a file which is too big...
1. when the httpRuntime.maxRequestLength has been exceeded and
2. when the uploaded file is under then httpRuntime.maxRequestLength
For point 1. it would be good to at least display a nice error page. IE
seems to just display a blank page.

I'm interested in an idiom for handling errors in functions without
using traditional nested ifs, because I think that can be very awkward
and difficult to maintain, when the number of error checks gets about
3 or so. It also gets very awkward in nested loops, where you want to
check for normal loop processing in the loop condition, not errors.
Yes, you could put some generic exit flag in the loop condition, but
when you're simply done if...

Exception may be thrown in the code inside the try block.
I want to handling the SqlException with State == 1 in a special way,
and for all others I want to use a general way to handle. Which of the
following options is better?

Option 1:
try{...}
catch (System.Data.SqlClient.SqlException ex)

I think I'm not quite understanding something about error handling in
PHP5. I have written some PHP code to index the contents of C drive
on a Windows machine. When it gets to certain special folders (fake
folders) it runs into errors. Directories it can not read from. I
have tried wrapping the code in a Try / Catch and the error still
comes through. What am I missing?

Overview:
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,...

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...
