Hi!
I've modified a javascript order form calculation script that tallies
up the subtotal, shipping/handling, and total automatically.
I did some modifications and it still worked fine, even in Netscape,
but at some point the Shipping/Handling field has ceased to display
correctly in that browser, showing a Not A Number error. (In Safari it
looks fine, and it calculates correctly in all browsers I've tested it
with.)

Hi Gurus
Does anyone know how I set the error trapping to option 2 in visual basic.
I know that you can go to tools, options and then choose on unhandled errors
only, but is there a VB command that I can use instead?
Cheers

Hi,
Does anyone here have a strong understanding for the meanings of the
terms "lvalue" and "rvalue" as it pertains to C, objects, and different
contexts? If so please share.
I've been reading several old posts/threads on the subject, and they
never end with a conclusion (people keep correcting each other and
disagreeing).

Hi!
I don't want to use eval() in order to parse a user-supplied formula.
What alternatives do I have? PHP has no standard functionality for
tokenizing or parsing expressions in this regard.
Here is a simple example: The user supplies the following formula in
string format,
"a = (6+10)/4",
and the script needs to find out what the value of 'a' is.

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,...
