Now I want to use the variable plus in an equation:
5 plus 7, just line 5 + 7
How do I do that?

Hi,
I get this error
error C3181: invalid operand for __typeof, expected a fully defined managed type
Whenever I try to use Enum in VC++ .NET, which is actually defined in my VC++ library (unmanaged code)
Is there any way so that I can perfom "Enum::GetName" on the Enum of unmanaged code?
Please suggest

Hi All,
I am trying to undestand "Type Conversions" from K&R book.I am not
able to understand the
bellow mentioned text
"Conversion rules are more complicated when unsigned operands are
involved. The problem
is that comparisons between signed and unsigned values are machine-
dependent, because
they depend on the sizes of the various integer types. For example,
suppose that int is 16 bits

I need the quantity entered in a field to be <= a certain quantity. I've opened the field properties and entered the following under the "Validation Rule".
<= ( sum ( ( ! ) Where ( ( ! = ) AND ( ! = ) AND ( ! = "Received" Or "Shipped" Or "Scrapped" ) ) ) )
I get the error message:
"The expression you entered contains invalid syntax."
"You may have entered an operand without an operator."
Any ideas or additional info needed?

Overview:
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,...
