A three-tier user authentication system was running without a problem for almost a year and now is suddenly dysfunctional. We don't know of any changes to any of the servers. It's quite maddening. The details:
1) We know the COM+ app is instanced on the COM+ server (Win 2000). The component graphic spins when CreateObject is called.
2) The proxy is installed on an IIS server (Win 2000) with delivers the interface, written in ASP, to the...

I am completely baffled when the following managed exception is thrown:
"Object reference not set to an instance of an object" from a nested
subroutine when referencing a variable allocated on the program stack.
Given the following simple example:
void T( System::String * S )
{
const wchar_t __pin * pchars PtrToStringChars( S ) ;

I suddenly received an unexpected error in my project. I have been working
on this project for some time without this issue. Nothing has changed in the
form that caused the exception. A little experimentation shows that I cannot
run ANY .NET web project without getting this error:

Object reference not set to an instance of an object.

I don't some Excel automation. I've created a program that opens and Excel
template and inputs information to it. It runs great on my machine. When I

Hello,
I've been banging my head against the wall for a few days on this.
When I run a page, either in "View in Browser" or I actually build the
solution, I occasionally and very randomly get the following message:
Object reference not set to an instance of an object.

This JUST started happening, I don't remember changing any code:
When I click the submit button on my form, stuff is supposed to happen
(which it does correctly) and a result message is posted back to the
same page at the top of my form alerting the user that their request
has been approved or denied. However, the end result is an error
message:
Error Message:
Object reference not set to an instance of an object.

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.
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...
