I have an A97 table with a Yes/No field named
TowJob and a form bound to that table. The
TowJob control on the form is bound to the same
field. It is an option group with Yes and No bttns
valued at -1 and 0 respectively.
Unless I specifically set the table field's defaultvalue
to Null, the form comes up with an automatic value
of 0 in the control? The control has NO default
value property setting. Why is that?

Hello!
What purpose has this Value propery on nullable types because it possible
to display their value without using it.
For example:
int? intNullable1 = 3;
int? intNullable2 = 5;

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,...
