Hi, I have a table where two fields will make up the primary key. In
a few cases the second field will be blank. When I try to append the
existing data into the keyed table I get the message that it cannot
append a null value into the keyed field.
Is there any way to set this up to allow the nulls in that second
field?
Thanks for any assistnace with this.

Hi Folks,
I have been given a CD with approx 130 .xls files (bean-counters!) that I
would like to import and merge to ONE table (tblTradeshow).
The XL files are *similarly*, but not identically structured, and the first
row does NOT contain field names.
Some (actually most) of the column names *are* the same in all of the
spreadsheets.

Can I set the Format property in a date/time field in code?

Can I set the Format of a Yes/No field to Checkbox in code?
I am working on a remote update of tables and fields and can't find enough
information on these things.
Also, how do you index a field in code?

In design view, say you habitually type descriptions for each of
the table fields you create. After many moons, many many tables
and many many many fields - you wanna delete each and every
table field description. Can that be done somehow using the
tables collection and the fields collection??? Any resource you
care to point out will be greatly appreciated.

I have a DataGrid that is configured to use the Edit/Update/Cancel concept
correctly. My grid shows values from 5 database fields. I only need to
update that last 4 fields. The last field is a Yes/No value in Access.
Using the OleDbCommand, if I do not consider the Yes/No field, the
ExecuteNonQuery command, using my UPDATE SQL statement, updates the record
correctly. However, if I put the Yes/No field into the mix, ExecuteNonQuery...

I've got a comboBox with 2 choices and based on the choice, I make

if choose choice 1, button A is visible
now, I undo the choice so that the comboBox is null, but button A is

I tried the field's onChange event, but no luck
I could use the form's timer event, but I wonder if there's a better

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,...

These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention.
