Hi.
This post follows "does python have useless destructors".
I'm not an expert, so I hope what I will write is meaningfull and
clear.
Actually in Python there is no possibility to write code that follows
C++ RAII pattern.
Of course Python objects are not statics like in C++, but in C++ the
auto_ptr class is used for enforcing this pattern for dynamical

Hi all,
I would like give users the ability to experiment with complex queries but
I'm worried about them creating queries that will bog down the server.
Does anyone have any ideas for preventing a runaway process?
I'd like to empower my users AND keep my server online :-)
Thanks!

Unlike register, auto keyword can not be used to

Dear all,
I create a big number of a class instances of some class. Sometimes this
instances must be collected (all pointers are deleted, but instance is not
explicitly disposed).But sometimes I need to notify all living instances to
reread an init file.
Since I don't want to prevent a garbadge collection of the instances I don't
have an explicit collection of all living instances. So I am trying to use
shared event for notification.

I am in the process of writing an application that detects the
insertion of a pen drive, and if a specific folder structure exists, it
shows a form containing data.
The problem is that when I insert the pen drive on some machines
running Windows XP, a windows explorer window appears containing the
contents of the pen drive. This window covers my application's window,
even if my application window opens a few seconds later.
How do I...

I have an application with a master form with a tab control containing
nine tabs, each tab contains a subform. I have command buttons on my
main form including: Save , Cancel , Close.
My question is, how can I prevent Access from auto-saving changed or
entered data on both the main form and any subform?
The main goal is to force the user to use the 'Save' button to save any
data. I need the 'Cancel' button to just undo any changes...

What is the best mechanism/ convention for preventing
stacked datagrids from overlapping each other?
I'd like to do something similar to a "can shrink/can grow" in an Access

for an aspx page which displays stacked grids.
For example:

Hi,
I have a Java/JavaScript GUI application where I perform a lot of long DB
operations
, which takes 5-60 secs to perform.
Sometimes user double-clicks the button or just gets impatient and clicks
again,
which created duplicate forcm submission and hence duplicate records.
So I am trying to disable the button as soon as it is clicked, and as soon
as it's done,

I'm working for the first time on an existing application that
communicates with an SQL Server database. We've backed up the database
and installed it on our own machine, and copied the ADB file to our
PCs.
One problem. We can't open up the ADB file. When clicked, with the
shift key down or not, it spends a long time in hourglass mode, and has
to be stopped via the task manager.
I don't know why it is ignoring the shift key (does...

you do not want the Power Option "Turn off monitor" to be anabled. Is there
anyway to fix this from VB.net? (note that I am not talking about the screen

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...
