Below is a routine I use for creating log files. It works great on most VB
Applications. However, for web services, it needs some help. The problem
is I cant reflect properly into a web service to find out where the .DLL is.
As is, this code writes a log file ok, but the log file ends up buried
directory deep inside the .Net Framework directories. Anyone know how to
find the path of a web service .DLL so I can fix this code to write to...

I am migrating my first vb6 app to vb.net 2003.
In the vb6 app a number of subs had optional date parameters:
Sub Fred ( ... ,optional FromDate as Date = 0...)
I need something like zero in there to see if the parameter has been used or
not.
In vb.net the imported code fails with:
Value of type 'Integer' cannot be converted to 'Date'

I got a similar idea a couple of months ago, but now this one will require
no change to the clr, is relatively easy to implement and would be a great
addition to C# 3.0 :)
so here we go..
To make things simpler and better readable I'd make all default parameters
named parameters so that you can decide for yourself which one to pass and
which not, rather than relying on massively overlaoded methods which
hopefully provide the best...

In our applications, we use the special value of DateTime.MinValue to
represent "null dates" throughout all our code. We recently ran into an
issue where we wanted an optional date parameter for a procedure. We weren't
able to declare it with DateTime.MinValue as its default value, as MinValue
is a read-only property rather than a constant. To work around, we had to
use a "magic date" that we checked for later on. I was never very happy...

Hi guys,
In the past I have used several time optional parameters in my
function.
But Now I am more inclined to think that they are more dangerous than
useful, and probably better to be avoided.
I'd like to hear your various opinions on this matter.

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:

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,...

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.
