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'm updating a record by opening a recordset, setting the fields and the
updating it with objRS.Update.
I need to set an image datatype to NULL. objRS("field") = NULL works for
datatypes int and varchar but not for datatype image, although there is no
error - the image field still contains the image!
I'm using SQL server and running an UPDATE statement including image = NULL
works.

I have a number of very common queries that the optimizer plans a very inefficient plan for. I am using postgres 7.2.3. I vacuum hourly. I'm wonderingwhat I can do to make the queries faster.
Here are the relevant tables:

I am trying to update a field of type IMAGE.
I am able to do this by deleting the record and then INSERTing a new record
as shown below in the commented section.
But I really want to do this with an UPDATE command as shown below in the
un-commented code. I assume this is possible.
The image is passed as a byte array called 'content'. I then want to update
the column STREAM with the new 'CONTENT'.

the prms go through except the binary image data. Using SQL server

Hello All,
I¡¯m using a context menu associated with some pictureboxes to provide
copy/paste functionality. Copying the image to the clipboard was easy. But
pasting an image from the clipboard is proving to be more difficult. These
pictureboxes are bound to an AccessDB. If the user wants to add an image,
they select an image using an OpenFileDialog:
Dim result As DialogResult = Pic_Sel.ShowDialog()
If (result = DialogResult.OK) Then

Is there a way in Javascript, or perhaps in HTML, to force a browser to
re-render an image on an HTML page after a round-trip between the client
and the server ?
In my particular case, the image is changing on the server although the
URL for it remains the same, but the browser is still displaying the old
image from its cache rather than the new image from its URL location.

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,...
