Hi all,
this post contains at the end a handy module that I've used quite often
when I wanted to analyse the occasional complex expression and how it
was to be evaluated.
The function analyse_expression is called with a single string argument
containing an expression. Names are allowed (actually, preferred over
numbers ;-), since the function eval's in a protected dictionary, where
names are generated as needed.

I am trying to run the following agregate function in a parameterized query
on Access2000:
Min(.*sqr(./.)/)
The query saved OK, but an attempt to run it results in the message:
The expression is typed incorrectly or it is too complex to be evaluated
If the sintax correct? Perhaps it is, otherwise it would not save.
What can be done about it?

I have struggled with the issue of whether or not to use Regular
Expressions for a long time now, and after implementing many text
manipulating solutions both ways, I've found that writing specialized
code instead of an RE is almost always the better solution. Here is
why....
RE's are complex. Sure it is one line of code, but it is on hell of a
line. Some of my RE remind me of the obfuscated code contest winners,
where one line of...

Is there an easy way (without duplication of the complex expression) to
use the same complex expression in all three places?
Will something like this work?
WITH (SELECT t.*, <complex expr> AS x FROM <base_table> AS t) AS wt
SELECT * FROM wt WHERE ABS(x)<10 ORDER BY ABS(x)

I am trying to get around the problem "The expression you have entered
is too complex" for a select query. (The example below is not the
expression that is giving me headaches.)
So I am thinking that I just need to do the parsing and calculating in
an event procedure for an "On Click" event.
My question is:
If I have a query field in access97 that parses date (in format

How can I create a property or function for a typed datasets column?
By this I need to add a new column (element) to the table or override an
existing column.
For instance I have an Invoice table that needs to have a Status property.
This status property has to read the other elements in the table to
determine what the status is and return a string.
I know that I can enter this in the expression fields, but as the
expressions become more...

In Linq, you can apparently get a meaningful body from and
expression's .ToString(); random question - does anybody know if linq
also includes a parser? It just seemed it might be a handy way to
write a safe but easy implementation (i.e. no codedom) for an
IBindingListView.Filter (by compiling to a Predicate<T>).
Anybody know if this is possible at all?

Hi,
I'm using Access 2003 on Windows XP.
My Error:
This expression is typed incorrectly, or it is too complex to be evaluated. For example, a numeric expression may contain too many complicated elements. Try simplifying the expression by assigning parts of the expression to variables.
I'm guessing that one of these calcs is the problem:
(/)*31 AS , (/)*31 AS , (/)*31 AS , / AS

Hi!
The words "expression" and "statement" are often used in C99 and C-
textbooks, however, I am not sure of the clear defintion of these
words with respect to C.
Can somebody provide a sharp defintion of "expression" and
"statement"? What is the difference between an expression and a
statement?

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,...
