I need a JavaScript timer - I have five events I need to time, that can be
triggered by a mouseclick event, or a keypress event. Each event is
separated by only one to two seconds.
The first event (mouse or key) starts the timer. Then, each time the event
(mouse or key) occurs, I need to display the present time in the
corresponding spot on the screen (so when it's over, the screen is
displaying five times for each corresponding event)....

With all due respect to Stan Leszynski and Greg Reddick, I'm still wondering
how to name controls on forms in my Access MDB.
Correct me if I'm wrong...
If a textbox or other control on a form is *bound* to a table field named
"FullName", then it should *not* be named "txtFullName", but rather just
"FullName" - that is, the name of the textbox on a form should always be the
*same as the name of the table field* it's bound to. And...

7.4#1 states
The header <ctype.h> declares several functions useful for classifying
and mapping characters.166) In all cases the argument is an int, the
value of which shall be representable as an unsigned char or shall
equal the value of the macro EOF. If the
argument has any other value, the behavior is undefined.
Why should something such as:
tolower(-10); invoke undefined behavior?

In the article, the description for
"Modiy DLL That Contains Consumers That Use Managed Code and DLL Exports
or
Managed Entry Points"
suggests the creation of the class ManagedWrapper.
If I need to build multiple mixed mode dll's used by a consumer application,
do I have to implement multiple ManagedWrapper's (each embedded in
indiviudal DLL project) and call all of them in my consumer application?

I have just started programming .NET having come from ASP.
We used to create a connection and store it in a session.This meant for each
user logging into the site there was only one connection
Now with ASP.NET using the SqlClient libraries this is not possible (No
doubt for good reasons).
So for each page before I need to access the DB I call
objConnect = new SqlConnection(connectionString);

Hi,
Have this following hierarchy which am implementing for a networking
program. The base class 'ASocket' is the base class from which
'AListener' and 'ATalker' inherit . None of the functions in the
derived classes would override functions from the base class. The
derived classes would extend the base class. A couple of doubts :
1. Should the functions in the base class be declared virtual ?

Hey everyone. I'm back in search of a better understanding of OOP. I feel like these past couple of months have paid off for me because I am at a point where I am really beginning to understand how this all works. I'd like to get some clarification on a few things first.
My questions stem from wanting to use private members and methods. I know that there is a reason for making methods and members public and private and honestly I'm still not...

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,...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
