I've been fighting with this issue for a long time. Let's say I want to do
something in a procedure only if something is not Null, not Empty, not
Nothing, not Missing, or not EOF. The conditional is always ugly. If there's
an Else condition, you can often reverse the condition to eliminate the
double-negative, but that can mean putting the If and Else parts in a less
logical order.
I figured out a while back that the loop until EOF issue can be handled
exactly that way = Do Until rst.EOF, so that helps, but sometimes, I still end
up needing Not rst.EOF.
I've been trying for a long time to figure out a nomenclature for functions to
invert these conditions that are not simply including the word Not in the
function names, and I finally think I've worked out a 1/2 way decent
nomenclature. It's idiomatic and imperfect, but so is the existing
nomenclature I'm working from, so if this or something like it became a de
facto standard, we would all get used to seeing and using it...
Current Antonym
----------- ----------
IsEmpty IsAssigned
IsNull HasValue
Is Nothing Exists
IsMissing IsSupplied
rst.EOF BeforeEof(rst)
Len(...) = 0 HasChars(...) Synonym would be EmptyString(...)
Other nice derivatives:
FirstAssigned(Arg1, Arg2, ...)
FirstHasValue(Arg1, Arg2, ...)
FirstExists(Arg1, Arg2, ...)
FirstSupplied(Arg1, Arg2, ...) 2 1369
