Greetings,
(I am an Oracle newbie -- been working with SQLServer for quite some
time, however. I'm using Oracle9i and Oracle9i JDeveloper v9.0.3.1
(build 1107) for my programming environment).
I'm trying to get an Oracle function to return XML to a JSP page, but
am having some problems (mostly Oracle errors). Let me start by
showing you what I've done so far.

I have read a number of posts on the use of eval() in Javascript, and I
agree that its use is questionable. But it does beg the following
question:
"How arbitrary does a string need to be before the use of eval() is
required to execute it?"
Given the following code, I'm able to evaluate/execute most expressions
like: "a.b.c.d()"

Hi,
It seems to be a generally adopted convention to have a function return
FALSE in case of an error. But if a function is supposed to return a boolean
anyway, one cannot distinguish anymore between the "normal" FALSE and the
"error" FALSE. So why not using NULL instead to indicate an error? Are there
drawbacks I am not aware of?
Greetings,
Thomas

Whats the common/best practice for returning a "Does not exist/not
found" result from a function. Imagine I've got a function:
myObjectType GetById(long id);
where the object may or may not be found. Currently, I just return a
null. But this muddies up the calling code with null checks and stuff.
Example:
I've got an Appoinment class, that has a property Doctor of class
Doctor. This property is lazily loaded, so I only store the...

This question was asked in comp.lang.javascript with no result.
In IE5.x and IE6, I want to display an image when the user rolls over a
text link. The image does indeed display, but only on the first
rollover. It seems that the image height and width become set to zero
after the image is displayed once; or perhaps that the
height:expression(eval(...)); code is executed only once for each page
load/reload.

FAQ Topic - When should I use eval?
-----------------------------------------------------------------------
The ` eval() ` function should _only_ be used when it is necessary to
evaluate a string supplied or composed at run-time; the string
can be anything from a simple (but unpredictable) expression such
as 12*2.54 to a substantial piece of javascript code.

I'm putting a radG:GridTemplateColumn together (which is probably
irelevant), and within it I'm using a Label, as so:
<asp:Label ID="defaultDescription" runat="server" Text='<%#
Eval("description") %>'></asp:Label>
Fo this Label, I'd like to only show the first 50 chars of the
"description", but I've no idea how to change the Eval to do this.. is
there a way?

I have a script that creates new objects based on the value of a form
field. Basically, the code looks like this.
eval ('new ' + objType.value + '(val1, val2, val3');
objType is a select with the different types of objects you can create
as values.
I really don't like using eval, and it's causing problems, like if I
do something like the following:

Hi,
Im currently looking to move into using JSON for AJAX instead of
returning from the server a string like the following:

can treat it exactly like an array - oSet = ...
Are objects just as quick to access/alter as arrays? I have a few

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:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

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,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention.
