The queue and condition class allow threads to wait only a limited
time. However this currently is implemented by a polling loop.
Now for those who like to avoid polling I have here a Tlock
class that allows for a timeout but doesn't use polling.
All comments are welcome.

Hi all,
I'm working on a report display page that currently uses 5
checkboxlists with a total of 86 items to display values from 5
different tables in an Access database.
The page works fine now. On presenting it to the users they pointed
out that their users could change the values in the checkboxes and
then print them out, ultimately documenting false information.

How does one make all controls on a Windows form read-only? Controls such as
check boxes, combo boxes and date time pickers dont appear to have a
read-only property. Disabling the controls makes them hard to read and you
cant select/copy the contents of text boxes.
Thanks

Ive got a time-critical application that runs on Windows XP and Unix. I've
got some timing issues that Ive traced to virtual memory getting paged in and
out. I think I can solve the problem if I can "lock" a certain huge memory
buffer into physical memory, so it is not paged out and in. The rest of my
program (code and other data) can get paged in and out: it is just this one
buffer that is critical.

Hi everybody,
I tried to find some information about my subject with google, but I
didn't find anything.
I need to read a text file, process the entire content, then kill. In
the meantime I have to be sure that no one could write on it. So I
opened with read write lock, but when i closed it, before deleting,
someone wrote something, and I lost the information because immediately
after I killed it.

I am working with directories in PHP for the first time. I have code
that I've changed multiple times to try different things. I would think
this is pretty standard fare so I'm not sure why I can't seem to get it
right.
What I would like to see happen:
The code opens the directory and loops through the files, opening them
and processing them.

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:

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,...

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...
