How does VB.NET determine comparing vs. assigning?
For instance, if "checkbox1.chec ked = True" it only checks the value but
leaves it as it whereas if you have "checkbox1.chec ked = True" by itself it
changes the value. Is that correct? I believe in C you have a "=" and a "=
=",
one for assigning and one for comparing. Am I understanding VB.NET
correctly?

In VB.NET, the '=' operator is /overloaded/ for assinging and comparing,
depending on the situation. Notice that 'a = b = 1' will result in
differewnt results in VB.NET and C#. In VB.NET, the 2nd '=' compares
'b' with 1 and assigns the result ('True'/'False') to 'a'. In other
programming languages, 'b' is assigned 1, and 'a' get's 'b''s value, 1.

Wow. This explains so much but seems so dangerous. You would think this
stuff would be better documented.

Ech... 'a=b=1' seems too messy to deal with anyway. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics | |

All,
I am comparing to functions to see which is "better". In better, I mean more
efficient, optimize, faster, etc.
I have read other posts from other boards, but I'm not really sure of the
benefits or if there is a speed increase
with one vs. the other.
FIRST VERSION
function is_active($module) {
global $prefix, $dbi;

Very basic question I'm afraid. Once an array has been declared, is there
a less tedious way of assigning values to its members than the following:
myarray=8;
myarray=3;
myarray=4;
myarray=0;
myarray=0;
myarray=1;
myarray=8;

I have a form which I am letting the user enter more than one event at

an error.
I am getting values like:

I am using this code for checking wether a value (form input) is an

a given minimum value:

if (!is_numeric($value) || (floatval($value) != intval($value))) {
$err .= 'Input must be an integer. ';

I need to write a function where the third parameter points to an

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,...
