I wrote my own Predicate class for .NET 1.1 which allowed composite
predicates using operator overloading...
for example:
Predicate p1 = {...};
Predicate p2 = {...};
Predicate p1andp2 = ~(p1 ^ p2); // ^ is the AND operator in logic notation

Hi,
M'm writing a program to output the results of transforming logical
predicates using deMorgan's. Does anyone know of a library that handles
logical predicates?
Cheers,

I'm trying to find CPP predicates that allow conditional compilation
based on the compiler's standard / features / extensions. So far I have
determined that, for GCC,
- __STRICT_ANSI__ implies -ansi.
- ! __STDC_VERSION__ implies -std=c89 or -std=gnu89.
- 199409 == __STDC_VERSION__ implies -stdc=iso9899:199409.
- 199901 == __STDC_VERSION__ implies -std=c99 or -std=gnu99.
I'd like to be able to

Hi, i've read that 'Col BETWEEN expr1 and expr2' became stage 1 and
indexable in DB2 UDB for z/OS Version 8.
Is there any way to find out which predicates are stage 1 and indexable
in V7/V8?
Had a look in the SQL references but no luck.
TIA, Markus

I've been looking at predicate delegates in connection with List<Tsearch
methods. My initial reaction is that the mechanism looks cumbersome, to the
point where I'm wondering if it's not just simpler to stick with a foreach
loop.
If I understand List<Tsearch predicates correctly, I'll need to write a
predicate, which is no big deal. But I will also need a member variable to
set the value of the search criteria that the predicate uses.

Hi all,
What does something like mean in an XPath query like /c/d ?
If I am not wrong, /c/d means return all d elements that their
parent is c and their grand parent is the root element and have a
child that is a and their a child has a child b. But I don't know when
we don't use an expression that starts with ./ or .// in a predicate
and instead use an epxression that starts with / or // what it would
mean.

Okay, after having bashed my head against this long enough I thought of you guys... I thought having exhausted just about every other .NET concept I would come back to predicates because Microsoft's "EndsWithSaurus" demonstration is beyond useless at explaining what this is useful for. Having previously understood delegates and got my head around those, predicates finally makes sense...although I still think Microsoft's example is ridiculous. I...

Inspired by Jon, I did a demo prorgram showing three ways to declare
predicates, in for example the "FindIndex" and "FindLastIndex" methods
of Lists, but in general you can do this for any predicate.
Note the most compact way is to use Lambda notation and anonymous
functions, the first way shown below. The most 'intuitive' way is to
'hard code' the predicate using a predicate method, the second way
shown below, but the best way (for me)...

Hi
I was using a query previously, that was efficient
select * from table where pred1 and pred2 and pred3;
Later I was asked to introduce new ones, but they were not based on
table columns but variables declared in SP.
select * from table where pred1 and pred2 and pred3 and variable1
='number1 and variable2 =number2;

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,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...

In this session, we are pleased to welcome a new presenter, Adolph Dupré who will be discussing some powerful techniques for using class modules.
