containing basic business objects. In order to improve performance these
lists are fetched and updated in the background.
When a UI is required to display one of these reference lists it requests it
by name from the cache. If the list already exists in the cache it is
returned to the caller otherwise a brand new empty one is created and
returned. This new empty...

Hi All,
I have a *.cer file, a public key of some one and I want to encrypt some
thing using this public key.
Can someone point me to a sample code for Encrypting some file using
X509Certificate ( *.cer file ) so that it can be used to email as
attachment.
The real part is Encrypting using X509Certificate and CryptoServiceProvider.

One of the things I've struggled with from time to time is handling
events raised on different threads. For example, an object could be
listening to events from one or more objects running in different
threads besides itself. There is a concern for thread safety. There are
various ways of dealing with this. One way is to make the class thread
safe by putting in locks. But another way is to stream the events from
the various threads into a...

What is wrong with my call below. If I change the
delegate and the CallBackComplete function to not take in
parameters then the .Invoke call works fine. As soon as I
put the parameters back I get "Parameter count mismatch."
error. Am I supposed to implement ISynchronizeInvoke in
order to call .Invoke? If so, why does it work when the
method i am trying to invoke has no parameters.

Now, I am aware of the

I have some .NET 1.1 code that utilizes this technique for encrypting
and decrypting a file.
http://support.microsoft.com/kb/307010
In .NET 2.0 this approach is not fully supported (a .NET 2.0 build
with these methods, will appear to encrypt and decrypt, but the
resulting decrypted file will be corrupted. I tried encrypting a .bmp

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,...

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.
