Hello,
I would like to prevent my perl program to be executed several times
simultaneously (if the program is already running, I would like to display a
message like "another instance of this program is already running, please
try again in a couple of minutes).
For doing this, I guess I have to check the running processes... but I don't
know how to do that and how I can identify my program in the running
processes.

I'm setting up an interface where clients must perform external
locking before calling certain commands. I do this to force them to
specify the duration the action they performed must persist before any
other threads can be allowed to perform some action.
My object exposes a Mutex which is locked via a IDisposable-Sentry
class. I want to throw an exception if certain functions are called
without this Mutex already being locked, but I...

How to obtain the lock status of a file held by other process?
If I read the file that is locked by other process, the read would
return -1.
If the file is locked by other process, how to put the read to sleep for a
second and try again after a period of time?
Thanx

Question one:
How do you detect if a file is locked. I have a program that is
cleaning up a temp directory and I want to scan the files to see if
they are locked before I try to delete them.
Question Two:
If the file is locked and I have admin privilages how do you take
ownership of the file and then delete it?

The only examples I have seen on how to check if a file is locked is to
try to open it a catch an exception.
MS has stated that you should never use error trapping in this manner.
Is there no other way to identify if a file is locked w/o trapping an
exception?

I found this thread about a pst file in Windows being locked and I am
having the same issue.

The problem is that I have a script that can find the pst files on
every machine in my network and back them up to a server for safe
keeping. The problem is that when Outlook is running it locks the...

Hey all,
So I have a script that runs pretty much every 5 minutes or so to look for updated files locally on a server. New files (ranging in size from 1KB - 2MB) are then FTP'd to another server. Without going into detail, one server is a content server, the other is a 'broadcast' server. Anywho, the problem seems to be with the FTP part. I'd say about 20 percent of the time, regardless of file size, something hangs up, such that the file...

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...

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,...
