Hi.
It would be great to be able to reverse usage/definition parts in
haskell-way with "where" keyword. Since Python 3 would miss lambda, that
would be extremly useful for creating readable sources.
Usage could be something like:
>>> res = where:
>>> def f(x):

Hi, all.
In 1998, I graduated from Computer Science Dept. in a university in China.
Since then, I've been using C Language for almost 6 years. Although I'm
using C++ in my current job, I'm also interested in understanding C more and
deeper at the same time. In the past half year, I decide to improve myself
on C, read some books on C and digest some posts on comp.lang.c and
comp.lang.c++. Now, I feel I have a better insight on C than...

if ($willLimitByDB) $sql = preg_replace('/#(+)#/i', '$$1',
$sql);
This does not give me the results I want, instead of the value of
$where in $sql, I literally get '$where' instead.
How do I substitute #where# with $where?
Thanx

My CATEGORY table does have one row where TCATEGORYPARENTID is null (real DB
null value).
TCATEGORYID and TCATEGORYPARENTID are uniqueidentifier columns.
My questions:
- is Type="Object", below, necessary?
- what shall I specify for DefaultValue in my function? I tried everything.

Background
Whenever code is used there must be a way to differentiate the actual code (which should be interpreted directly) with literal strings which should be interpreted as data. Numbers don't usually have this problem but Dates can too.
Debug.Print Me.ControlName
refers to a control on a form. Whereas,
Debug.Print "Me.ControlName"
simply prints the literal text
Me.ControlName
Where to Use Each Quote Type (' or ")

I was hoping for increased functionality with the where clause in C#
3.0. Using the new keyword 'var' would really allow us to take nice
advantage of these. Specifically:
1. I want to limit it to primitives: "where T : System.Type.Primitive"
or something like that.
2. I want to limit it to an unspecified generic: "where T : List<>".
3. I want to limit it to a generic with a subset of types: "where T :
List<new TTwhere TT : class" or...

Dear Experts,
I have a fairly simple query in which adding a where clause slows
things down by at least a factor of 100. The following is the slow
version of the query

ON x.event_date = y.event_date

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:

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,...
