Hi.
Just as we have AVG(COLUMN_NAME) and MAX(COLUMN_NAME) how can I write
my own variation of a such a function. If I can appreciate how to do
this,
then I hopefully I can write a MEDIAN(COLUMN_NAME) type function or a
more general function like a 10% percentile function with syntax such
as
PERCENTILE(COLUMN_NAME,25).
Regards JC......

In Microsoft's help literature, it states:
"You can filter out non-unique rows by using the DISTINCT option of an
aggregate function"
I am trying to do this in Access 2003 with the COUNT aggregate
function, but there is no reference, at least that I can find anywhere,
of how to do this. I have multiple lines fields for which I would like
to do a "count distinct", but for simplicity, I am showing an example
of only one field. Here is...

I've read that the expression property for DataColumns is used to "Sets or
retrieves the expresssion used to filter rows, calculate the values in a
column, or create an aggregate column.".
I have seen examples on how to filter a column, but how would I filter out
an entire row depending on the value of a column?
For example, if I wanted to filter out every row in a multi-column table
where the "Is Fubar" column equals "true", how would...

Hello,
I created a datalist in an ASP.Net / VB page.
I display the image and price of a few products.
When a user clicks an image I want to load the page
"detail.aspx?number=id" and send the value of the "id" field of that
record as a URL parameter.
Can someone tell me how to do this.

just wasted a long time figuring out this and I figure if I post it
might save someone some pain!
Jet (DAO) will allow you to to use nested aggregate functions like
building blocks, e.g.:
SELECT
A,
sum(B) as Answer1,
Answer1 * 2 as DoubleAnswer

Hi i have been struggeling with this question for quite some time now.
I have some helper classes that handle images (upload an image, create
thumbnails and show a imagelist), links (add link, edit link, show
linklist), comments (add comment, show commentlist) etc.
I do not need all this functionality on every page.
Ideally I could just extend the controller like this

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:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

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,...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.

I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
