I'm trying to find an equivalent of key-event trapping which is easy in
QBasic. Several of my programs build up a geometric figure with two
parameter line families, eg with two nested for..next loops; after that, the
process is redone, or moves on to a new position of the same figure. With a
slow system each build-up may take some time. But after, say the inner
for...next loop it's easy to scan for a key-event with an a$=inkey$ command...

I'm trying to improve my code so that when I open a recordset object,
I can absolutely guarantee it is closed and is set = Nothing. I have
read some old threads and they all say to use the functional
equivalent of the following code:
Public Sub CloseRecordset()
On Error GoTo Sub_Error
Dim rs As Recordset
rs.FindFirst "This Will Error"

I have an Access 2000 database with a form that is giving me some
major headaches. When you open the form, it displays all records and
allows editing, but has AllowAdditions set to False so that the user
has to use my New Record button. When you click the New Record
button, the form presents a new record for editing. My client wants
to use the Escape key to cancel changes to new or existing records.
On existing records, Access already...

Hi there,
I am having difficulty with a piece of code which would work wonders
for my application if only the error trapping worked properly.
Basically, it works as follows:
- adds records from rsSource into rsDest
- if it finds a key violation then it deletes the current record from
rsDest and adds the new record from rsSource. This works perfectly -
but only for the first found duplicate record, it brings up the error

Hi Gurus
Does anyone know how I set the error trapping to option 2 in visual basic.
I know that you can go to tools, options and then choose on unhandled errors
only, but is there a VB command that I can use instead?
Cheers

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...

Hi all,
I was wondering if anyone has had any luck with trapping the <BODY>
onUnload() event in ASP.NET?
The thing is, I'm writing code for an Intranet site. The code makes a
call to a third-party component (think of it as a lock) when the page
loads. Now the OK and Cancel server buttons I can handle and use to
release the lock as required. But previously in classic ASP I had
been trapping the user hitting the close 'x' button by...

I'm still using Office 2000 myself, but some of my clients have Office 2003.
I've recently added a piece of code to create an instance of Word, open a
document, fill in the blanks and become visible so the document can be
printed and/or modified.
This all takes place within one form, in which the Word.Application and
Word.Document objects are both private form-level variables. Just to be on
the safe side I included this piece of code in...

Pretty new to PHP, I recently started learning about error trapping.
As of right now, I include the following into a page in my website:

error_reporting(E_ERROR | E_PARSE);
set_error_handler("SendErrorReport");
function SendErrorReport($errorNumber, $errorMessage, $errorFile,
$errorLine, $vars)

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...

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...
