dimensional array. But, it doesn't work. Could anyone tell me what's
wrong with my code. My code is as follow:
<html>
<body>
<script language="javascript">

Hello,
In some examples of a PHP implementation I saw the following:
if ( isset(x) and x==12)
I do not understand what for before to check whether some variable has
some value one need to check whether this variable is set. If the
second condition is true than the first one is also true, isn't?

is there anyway to check if a string could be used a variable name. So
return false if the first character isn't a letter or if it contains
spaces etc.
I started writing a function that would do a load of tests because I
couldn't see any easier way of doing it:
<?
function is_valid_handle($str) {
// determines if the string provided can be used as a handle

Hi all
In my functions I'm using a double-check all the time to trap if a value has
nothing in it and my question is do I need this double-check.
My check line is:
IF IsNull(xxx) OR LEN(xxx) = 0 THEN
blah blah

I have a Customer table. The table has two different CHECK constraints.
Then there is the Customer details dialog, which provides the user with
an UI for changing users. I have some UPDATE sql, which is called once
the user clicks the OK button on this dialog.

int rows = cmd.ExecuteNonQuery();
}

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,...
