I'm trying to build a function that reads each character in a string
and converts it to an ASCII numerical value. So far, so good.
However, I'm running into problems when dealing with quotation marks.
Using ASC(""") dosen't work, neither does ASC('"') or just ASC(").
Is there any other way to handle this? Is this the only character I'll
have this problem with, so should I just error trap it?
Thanks!

Folks,
I need to try and make sure that a given string is a valid numerical
value (not just int, or int32 - it could be float, decimal, what have
you). VB.NET has a neat "IsNumeric" function - too bad C# doesn't have
anything similar. Or does it??
I was thinking about trying to convert the string to Int32, but as I
mentioned - that alone won't be good enough, and I really don't want
to attempt a dozen conversions to find out - nor do...

Hi,
I've made a program from numerical recipes. Looks like I'm not allowed
to distribute the source code from numerical recipes but it shouldn't
even be necessary to do that.
My problem is that I'm not very experienced with pointers, pointers to
pointers and the like and I got 4 compiler warnings + I don't completely
understand how to build this "compact matrix" (see later).

Hi
I am just starting on Visual C (2003) from a VB background. I find it easier
to learn by actually programming. I have fallen over at the first hurdle.
How do you extract a numerical value from a text box? I have a number of
reference books but it is not mentioned because I guess it is simple and I
am just missing it.
Regards

Hi,
I have a listview which has columns of text and columns of numerical
data.
I need to be able to sort these columns into ascending/desending order
whenever the user clicks on the column header.
The text columns are sorted correctly but the numerical columns seem
not to get sorted properly.
For example I get the following result when I try to sort a numerical

Hi all,
I am trying to find the numerical value of a string that stores a two
digit number. I have found the numerical value of a char as:
char character;
cin >character;
int number = character - 48; // Computing the numberical value of
character entered
cout << "The number you entered is: " << number << endl << endl;

hi
i need a fast way to do lots of conversion that between
string and numerical value(integer, float, double...), and
boost::lexical_cast is useless, because it runs for a long time,
(about 60 times slower than corresponding C functions)
it's too expensive for my program.
is there any way( library?) to do this fast and safely,
please ?

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,...

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...

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...
