It's official....Convert blows.
I ran a number of tests converting a double to an integer usingboth Convert & CType. I *ASSUMED* that CType would piggy-back ontop of Convert, and that performance would be identical.
I was 100% incorrect.
The code below produces the results:
CType Took: 0.2187528 seconds.
Convert Took: 12.187656 seconds.

Need a little help here. I saw some related posts, so here goes... I have some textboxes which are designed for the user to enter a integer value. In "old school C" we just used the atoi function and there you have it. So I enquired and found the Convert class with it's promising ToInt32 method, great... but it doesn't work. The thing keeps throwing Format Exceptions all over the place. What is the "C#" way to do this??? code

What is the best way to convert a managed unsigned int64 to an
unsigned long? Basically I need to do the following:
System::UInt64 managedInt = 10;
unsigned long unmanagedInt;
unmanagedInt = managedInt;
Also it would be nice to know how to do this:
System::UInt64 managedInt;

Hello,
what has the better performance and what are you using?
Dim myObj As Object = 70
a) Dim myInt As Integer = DirectCast(myObj, Integer)
b) Dim myInt As Integer = Convert.ToInt32(myObj)
Thanks,
Andreas

In VB6, foreground and background colors of controls had to be assigned a
single number. If you knew the RGB values for the color, you still had to
convert them into the single number accepatable to the VB6 controls.
In VB.NET, you can't set colors that way anymore, now you have to use a
"color". There is a way to convert RGB values to a "color", using the
Color.FromARGB method. But there doens't seem to be a way to convert the old...

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...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
