'is not' or '!='A newbie question to you; what is the difference between statements
like:
if x is not None:
and
if x != None:
Without any context, which one should be preferred?
IMHO, the latter is more readable.

"x == y" tells you whether x and y refer to objects that are equal.
"x is y" tells you whether x and y actually refer to the same object.
In the case of singletons like None (there's only one None object),
it's better to use "is".

Do the following: take two $10 bills. Hold one bill in the left hand,
hold the other bill in the right hand.
Now, the bill in the left hand "is not" the bill in the right hand.
However, the bill in the left hand "==" the bill in the right hand.

In almost all cases, both tests would result in the same behavior.
However, the "is not" test is conceptually the correct one since you

'''''''''''''The Running Update/Append Queries Using VBA code Ordeal'''''''''''''' #2Hi,
Thanks for ur help there HJ.
I know how to do the tasks you specified there.
I would like for the update query to use field values from some of the
fields on the form (frmInvoices) such as InvoiceNumber, DateFrom,
DateTo. My problem is that an append/update query can't find the
values in the open Form (frmInvoices) when I specify them as;
[Forms]![frmInvoices]![InvoiceNumber]
a select query has no problem finding the field values on a form.
please help.

Hi Aaron,
Could you post the entire code that you are having trouble with? Now it is
not possible to see what goes wrong.

First off, if you are not always using all the parameters specified in
your form, then you have to add parameters to your query on the fly.
Also, you can't just do something like

Bad taste? It returns T if the list X contains nil as an element. It
would be clearer to write (some #'null x).

is there a function implemented doing this conversion?
my Problem is, that I want to use the following code:

No, they are not the same thing. == and != test to see if the *value* of
two variables are the same. Like so:
>>> a = 'hello world'
>>> b = 'hello world'
>>> a == b
True
a and b both have the value of 'hello world', so they are equal
is and is not, however, do not test for value equivalence, they test for
object identity. In other words, they test to see if the object the two
variables reference are the same object in memory, like so:
>>> a is b
False
a and b are assigned to two different objects that happen to have the
same value, but nevertheless there are two separate 'hello world'
objects in memory, and therefore you cannot say that a *is* b
Now look at this:
>>> c = d = 'hello world'
>>> c == d
True
>>> c is d
True
In this case, they are again the same value, but now the is test also
shows that they are the same *object* as well, because...

'[OFF]' as in 'offensive'???Hi,
given that 'off-topicness' is indicated as '[OT]' and taking a look at
those postings that started the threads indicated as '[OFF]' (which may
both be seen as being somewhat offensive) may lead to the conclusion
that '[OFF]' stands for offensiveness.
I don't think that this is the intended meaning so what actually *does*
'[OFF]' mean? I never came across that abbreviation before (although I
have been around on the USENET for quite some time) but maybe it is
worth knowing?

'!' vs. '.'Is there an advantage to using the '!' notation to represent form/

I am currently using the '.' notation exclusively (for code completion
in the VB Editor), but much of the high-quality code that I've seen
(in Duane Hookom's Query-by-Form db, for example) uses the other.
Here's one opinion for you: http://doc.advisor.com/doc/05352

Here's my $0.02 worth on this.
I tend to copy the notation style and naming conventions that I see being
used in the Help files.
That would be Me![text1] for a control on a form. I am of the belief that
this notation explicitly refers to a control itself rather than a field in
the form's recordset.
Here's an example:

3-character abbreviation for a brand name, and is the na...

In Gforth itself, there is no difference. In Gforth's cross compiler,
"a," is there for addresses, and "," is there for other cells;
addresses can then be relocated when loading the image.

Re: if str_mo not in ('','.') and str_da not in ('','.') and str_yy not in ('','.') Any shorter ? #2Igor,
There are many ways to make it more concise, however the parsimony is likely
to be achieved at the expense of clarity. For instance, the expressions
length ( input (mm||dd||yy, $10.) ) > 2
length ( compress(mm||dd||yy, ' .') ) > 2
and like might be somewhat shorter than the original, but they will execute
slower, and their intent is far less eminent. Since it appears that you are
trying to validate the components of a date, maybe it is not a worthless
idea to try the date informat conforming to the mask you are testing. Say if
all the pieces are 2-digit, the expression
input (mm||dd||yy, ?? mmddyy6.)
will return a missing value for the case you are testing and also if any
irregularities in the input value that prevent it from being interpreted as
a valid date should be found. And if you want a note in the log to alert you
about it, leave one of the question marks off.
Kind regards,
