When creating a new class, is it encouraged to always include error
handling routines within your LET and GET procedures? It's seems that
most text books never seem to include much about error handling within
classes. Just hoping to hear some programmer's thoughts on error
handling.

Hi,
assert and error handling can be used for similar purposes.
When should one use assert instead of try/catch and in which
cases the error handling is preferable?
I've read somewhere that assert could be used to start
an interactive debugger automatically. How do I realize that
on a Linux machine using gcc?

I have a command button on a subform to delete a record.
The only statement in the subroutine is:
DoCmd.RunCommand acCmdDeleteRecord
The subform's recordsource is "select * from tblVisit order by VisitDt"
I'm getting this error message:
Errno is 2465. Err.description is "Can't find field '|' referred to in your
expression"

I use code extensively; I probably overuse it. But I've been using
error trapping very sparingly, and now I've been trapped by that.
A form that works for me on the system I'm using, apparently runs into
problems on the system where it will actually be used, and since I
used so little error-trapping it dies very ungracefully.
I will of course try to fix whatever is causing the error and add
error-trapping to the functions where the...

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...

Hi all
I'am moving from Visual Foxpro and have a question
regarding "best practice" error handling in vb .net.
In VFP I have always used a "central" error handling
object in order to have a easy and reusable way of
handling all errors in a program.
The VB 6 coding examples I have seen there has always
been error handling code in each program module.

Hi,
I have error handling in place throughout my application. I also start the
application wrapped in error handling code to catch any unexpected
exceptions (i.e. exceptions that occur where I haven't placed error handling
code).
When I run my app from the IDE, the unhandled errors are caught by the error
handling code in my Sub Main routine and the error details are logged to a
text file and optionally e-mailed to me for follow-up.

and after that much typing, I don't want to lose it)
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.

Thought I would give something back with a few articles. This article is a bit of code to add error handling. When I have time, I want to write articles on multilingual databases, and Access Security, but I'll start with something short and simple
This code was written in Access 2003 but should be valid in Access 2000
By default, when you start a new module, either in a form or report, or a global module, Access does not declare Option...

Hello guys!
We have an SQL server which sometimes makes timeouts and connection errors. And we have an function witch writes and updates data in 2 tables on this server. When the SQL server error appears it, in 99%, of the cases, works if we just press the play button in VBA debug. Therefor we have maked an error handling which just tryes again.
However, as this error handling is difficult to test because of maybe 1 or 2 errors a day, we...

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:

Here is the code in...

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,...
