Hello,
In a search form, i want to permit few characters (see below) and some signs
as - _ / , .
So thios my RegularExpressi on and it works.
ValidationExpre ssion="[a-zA-Z 0-9-_/,.]{4,20}"
But i'd would like to permit the sign ? in my string, but only one or two
occurence., like this.
Search : 123?456?
I don't manage to do it. All my tests are wrong.
thanks.

You could try this:
([a-zA-Z 0-9-_/,.]+[?]?){0,2)[a-zA-Z 0-9-_/,.]*
but then you lose the maximum-length check.
explanation:
- one or more of your characters
- optionally followed by a ?
- the above repeated 0 to 2 times
- possibly followed by characters

I have a regex "^\d{5}$" that does not allow blanks, but the

way to make it do so? I would rather not include a separate

Thanks,

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:

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,...
