Quick Question:
StringBuilder is obviously more efficient dealing with string concatenations
than the old '+=' method... however, in dealing with relatively large string
concatenations (ie, 20-30k), what are the performance differences (if any
with something as trivial as this) between initializing a new instance of
StringBuilder with a specified capacity vs. initializing a new instance
without... (the final length is not fixed)
ie,

On the advice of a user, I've timed stringbuilder v string. Here are the
results.
Here are the numbers:
Total # queries 3747
Time in Milliseconds
StringBuilder: String

I need to loop through a string and remove all characters except numbers or
letters. I am getting an ArgumentOutOfRangeException: "Index was out of
range. Must be non-negative and less than the size of the collection"
Not sure what is going on... any suggestions welcome!
public static string fixStr(string aStr)
{
StringBuilder bStr = new StringBuilder(aStr.Length);
for (int i = 0; i < aStr.Length; i++)

Hi,
I know this has been asked before, but reading the threads it is still not
entirely clear.
Deciding which .Replace( ) to use when.
Typically if I create a string in a loop I always use a StringBuilder. At
present I am
porting a VB6 webclass app to VB.NET and therefore I am trying to make it as
efficent as possible via the new functionality of VB.NET.

I thought that the whole point of StringBuilder was that it was supposed to
be a faster way of building strings than string. However, I just put
together a simple little application to do a comparative analysis between
the two and, surprisingly, string seems to out perform StringBuilder by a
significant amount. A string concatenation takes not quite twice as long
using StringBuilder than it does with a string. This doesn't sound right to...

Ok well i thought i'd try a different approach, so what I'm now trying is
appending 50,000 lines from the collection to a stringbuilder, and then
writing that entire stringbuilder to a file.
However, look at this log:
21/04/2006 14:09:06: Building String Start
21/04/2006 14:09:14: appended 10,000 lines to the stringbuilder

Hi,
It is generally stated that stringbuilder should be used instead of
just concatenating strings with the plus operator.
That's fine enough what I'm wondering in cases I have:
String S = "hello" + World;
Does it make any sense to use Stringbuilder in a case like the above,

StringBuilder better and faster than string for adding many strings.
Look at the below. It's amazing how much faster StringBuilder is than
string.
The last loop below is telling: for adding 200000 strings of 8 char
each, string took over 25 minutes while StringBuilder took 40
milliseconds!
Can anybody explain such a radical difference?

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...

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...
