I am converting a VB6 WebClass application to VB.Net. Used the VB upgrade
tool to do the conversion - and it left me a lot of little code things to
do. Did those code things and got my app to compile. Did a few other code
things to take advantage of .Net features not available in VB6.
When I start the application on my PC I get the error shown below. It seems
to me that the app initiation is failing before any app code is executed.

Hi all,
I guess I don't fully understand how a SHA1 hash value is calculated
in C# / .NET for a large file... I'm trying to calculate SHA1 values
for large files that are much larger than my physical main memory. It
seems the way to derive a SHA1 value involves opening a file stream to
the large file, passing it to a byte array, and passing the byte array
to the .NET hash method.
Does this load the entire file into main memory (within...

I want to create a file hash on my exe files and store the hash signature in

Is the code below valid? Generally a value must be accessed
through the same type it was stored as, but there is an exception
for data stored through a character type. I'm not sure if that
applies in this case though:
#include <limits.h>
unsigned foo(void) {
static const union {
unsigned char str;

How can I add an MD5 hash to XMLSerializer.Serialize without corrupting the
content of the file; then how to read it back to verify is correct?
I'd like to code up something (see below) that looks like this, but I'm not
sure this is correct approach to the problem. Once I add the signature, the
file won't test the same way again. I know I could add it to the bottom of
the file, but then everyone would have to know my algorithm for...

Hi -
I'm trying to calculate unique hash values for binary files,
independent of their location and filename, and I was wondering
whether I'm going in the right direction.
Basically, the hash values are calculated thusly:
f = open('binaryfile.bin')
import hashlib

I'm having difficulty trying to figure out how to print a text file from a hash table one line at a time. I have the text file read into the hash table and can print the text file all at once, but I can't seem to figure out how to do it one line at a time.
Here is what I'm trying to do: I want the user to be able to print the text file one line at a time by clicking a button to see the next line.

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

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.

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...
