I am interested in hearing opinions on the semantic meaning of FORM (elements) in HTML. I have to start of apologising because this question arose in a context that is not applicable to the Internet. Specifically, marking up a document that will contain multiple related form controls (intended exclusively for client-side scripting) that would never be intended to be submitted.

Hey guys, I'm new here, just a simple question. I'm learning to Program in C, and I was recommended a book called, "Mastering C Pointers", just asking if any of you have read it, and if it's worth the $25USD. I'm just looking for a book on Pointers, because from what I've read it's one of the toughest topics to understand. thanks in advanced.

Hi all, I am reading "C: A Reference Manual" 4th ed and I get lost for the "extern". It says that global object without specifying the storage-class specifier will have "extern" as the default storage-class specifier.

I'm working on examples of programming in several languages, all (except PHP) running under CGI so that I can show both the source files and the actually running of the examples online. The first set of examples, after decoding the HTML FORM contents, merely verifies the text within a field to make sure it is a valid representation of an integer, without any junk thrown in, i.e. it must satisfy the regular expression: ^ *?+ *$ If the...

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,...
