Hello there,
I am at my wit's end ! I have used the following script succesfully to
upload an image to my web space. But what I really want to be able to do is
to update an existing record in a table in MySQL with the path & filename to
the image.
I have successfully uploaded and performed an update query on the database,
but the problem I have is I cannot retain the primary key field in a
variable which is then used in a SQL update...

I have a system that basically stores a database within a database (I'm
sure lots have you have done this before in some form or another).
At the end of the day, I'm storing the actual data generically in a
column of type nvarchar(4000), but I want to add support for unlimited
text. I want to do this in a smart fashion. Right now I am leaning
towards putting 2 nullable Value fields:
ValueLong ntext nullable
ValueShort nvarchar(4000)...

I'm building a system when one can upload a document to the website.
I will be storing the document on the hard-drive for quick/easy access,
but I was also thinking of storing it in an existing database since most
of the sites information is all stored there.
As well there would be only one place to worry about backing up. And if
the file on the hard-drive was ever missing or became corrupted, I could
restore it form tha database. Is...

Hi,
I am currently writing a news admin system. I would like to add the
ability to add images to each article.
What I have always done in the past is uploaded (using a form) the
image to a folder on the server and then in the database table that I
INSERT the news article, I'll store the path of the uploaded image.
To me this seems a bad idea as if the image paths were changed on the

Dear All,
What's the best way to store jpgs in postgresql to use in a web page?
I tried to use large objects, but how would you extract them from a table to
be viewed in a web-page without having to write them to a scratch file
somewhere first?
Thanks

User wants to go this route instead of storing pointers in the DB and the
documents outside.
Only time I tried it was with only MS Word docs - and that was a loooong time
ago - and it seemed to me like there were performance issues at the time.
How about the different types? The MS docs I would expect Access to
differentiate and handle appropriately (i.e. .DOC and .XLS).. but how about
..PDF? and can I stash a .TXT document in the...

Hi,
I need to add photos to my database. Back End is on MS SQL Server (I
believe 2000), and Front End is on MS Access.
I have read about storing the photos as BLOBS, but I am not sure how
to do this with SQL Server. Does this mean store the photo as OLE
image, but do something else to it to make it a "Blob"?
I have also read about linking to the photo rather than storing it on

I was wondering if anyone had any advice on this.
This is not to study graph theory; I'm using the graph to represent a
problem domain. The graphs could be arbitrarily large, and could
easily have millions of nodes, and most nodes have a substantial
amount of data associated with them. Obviously I don't want a whole
such graph in memory at once, so libraries the just deal with in-
memory graphs are out.
I know I could implement 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...

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,...

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...
