I think I know the answer to this, but suggestions welcomed.
I have to store lots of information. An electricity reading every half
hour for hundreds of meters for several years.
The ways I thought of storing this in SQL were:
1. One table row per day with 48 fields for the readings.
144M table, 3M index
saves space and having a long skinny table
however, getting the min/max reading in a day is a pain. I

I have a client who would like to have several pictures associated
with one system. I have read about storing only the pathname to save
OLE overhead and have set-up a form for my client to browse/add one
picture at a time to a system. Now he would like to 'view' all of the
thumbnails associated with any system on a single form.
I can setup a main/subform scenario, but how do I show all of the
pictures as thumbnails. I was using the...

Hi,
I've got 10 image thumbnails generated with GetThumbnailImage down the side
of each page of a site. However it seems the thumbnails are being
re-generated with every page request rather than cached in the browser. Is
there a way to cache the thumbnails or would I be better saving them to a
file? The thumbs change every hour so I really wanted to avoid having to
create a file for each one

I am creating dynamically some Office documents in my ASP.NET application. When I want to send the resulting document to the client, I am currently saving it to the local disk and then redirecting user's browser to it.
Is there any way to skip this saving phase, i.e. to send the document directly from memory?

My question is similar to one someone posted a few months back, but I don't
see any replies.
Basically I want to be able to have users upload photos and save them in a
database (as byte data) and be able to load them to an image webcontrol, but
system.web.ui.webcontrols.image only seems to have a control to load the
image from a URL.
There's no way to load this directly without saving the image as a file and
then using...

I have a gallery-like application. (The gallery will be actually presented
in Flash, but the management (cms) of the images will be in asp.net. )
My question is, is it ok to create Thumbnail images on the fly by resizing
the original sending it to the output stream (i.e. Response.ContentType =
"image/jpeg"; Response.BinaryWrite(imageContent) ), or best to actually save
the thumbnails to disk.
Would this method result in a much slower...

Hi all,
It may seem like a rather odd request (or not) but I would like to be
able to create a file (doc, jpg, xls or one of many other files that
can be automated) on a website and stream it to a user without saving
it to the disk first.
Obviously saving the file first and streaming it afterwards is fairly
easy to do, but it relies on disk write permissions on the server and
you'd have to make sure the file was removed afterwards.

I have a databse containing amongst other things many images stored as
BLOBS.
When listing, currently I download all the images full size and let he
browser do the reduction to thumbnails.
It's getting a little slow on long lists.
Is there anyway to take the data and scale it down on the fly to a
smaller image? I have plenty of processor power, just not much bandwidth.

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:

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...
