IsNumeric(value) should return false if value "can not be
successfully converted to a Double." Instead I get the
following error message: "Input string was not in a
correct format."
I use the following function in a validating class to use
when needed. (Value = H880118A gave the error (like
other 'unconvertible' strings))

I have received the following feedback for the two functions bellow:
"The ISNUMERIC test is WORTHLESS for checking for an INT value, because
ISNUMERIC will happily accept DOUBLE values, such as 89.11998811777 and
other values that are simply *NOT* INT values."

Hello,
Does anyone have a good/reliable approach to implementing an IsNumeric()
method that accepts a string that may represent a numerical value (eg. such
as some text retrieved from an XML file)? Thus if you pass it "1" or
"5.12345" it returns true, but "1b3q" it returns false? I know VB has this
sort of function, but was wondering how to implement something similar in
C#. I suppose I could use the Convert methods and catch any...

Hi,
is there a dotnet function (other than the old isnumeric from VB) to check
whether an object is numeric or not.
also I notice that all the old vb functions such as split / isnumeric /
ubound etc are still availible by default in any VB.net web application.
is this because the vb library is being imported??
would it be best to totally remove this library (assuming that it is being
imported - which I can't see in my references) so...

All,
I think I may have uncovered a bug in the IsNumeric function, or at least a
misunderstanding on functionality.
I am writing a Schedule Of Classes Application for our campus and have a
section that lists the Times, Buildings and rooms for courses.
In this section I have a function called PadCell that takes3 parameters, one
the value, one a padd count and one a a boolean input called StripNumeric,
that if true, checks if the value...

What's the .net framework equivalent of the vb function isnumeric? If there
isn't one, how can I test a string variable to see if its a number or not?
I don't want to use isnumeric if possible

Hi,
I am trying to check a string to see if it's first 3 characters are numeric
and if they are, to replace those 3 characters with something else.
I've tried this but nothing happens...
newname = Replace(newname, VB.Left(newname, 3) = "101-", "101. ")

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:

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,...
