Let's say I have an html form with 20 or 30 fields in it. The form
submits the fields via POST to a php page which updates a table in a
database with the $_POST vars. Which makes more sense?
1) simply UPDATING the values for all fields in the table, whether or
not any particular field has actually changed
2) running a second SELECT statement and comparing the $_POST vars to
the returned values, and only UPDATING those that have...

I have a problem wherein a query that updates a GridView doesn't seem to
really stay in sync with a label I have above the GridView.
I have a GridView object that I'm updating with information whenever my
user enters a job number into a textbox and hits a button. There is a
SQLDataSource object on the page that does the retrieval of the data, and
the job number parameter for its query is bound to the textbox "Text"
value. In the button...

Unless my app is EXTREMELY simple, I get the cross-threading error message
regularly when updating controls on a Windows form.
My latest example involves a dll that runs a System.Threading.Timer,
updating private shared variables. When it finishes updating, it raises a
NewData event. My app responds to that event by updating display controls
(labels in this case). I have to use a delegate and update them like this:

Suppose I have a windows form (.exe) that has a load of labels and
text boxes on it.
I enter a number into one of the text boxes and hit the search button.
This then launches another thread, which may or may not spawn other
threads.
What's the best way of updating the user interface?

I have been fighting with trying to update a GridView for a while. I
don't want to use the "built-in" way to do it because I am using
business layer methods for updating and deleteing and I don't want to
have my parameter names in those methods have to be
"original_Parametername" or even if I change the
OldValuesParameterFormatString to get rid of the "original" I would
still have just "Parametername". I think most people user parameters...

I have a winform app (VB 2005) that allows users to export data to
excel, make updates to the excel file and import the data from that
Excel file and update the database.
My question is: Is it best to do it this way, calling the update
stored procedure for every update? Or should I be loading this data
into a staging table, and if all goes well do the 'Real' Update. Or
put this into a data adapter and update from that? The application...

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
