Hi Everybody,
I have an issue about deleting an object from an arrayList.
I've bounded a datagrid using this code
where it will first run through all of the code in loadQuestions() and bind
a arrayList to the datagrid.
private void BindQuestions()

I am trying to create an arrayList that contains multiple arrayLists.
My code attempt is below. The question I have is how can I get away
from creating another pAttribute list than can be added to pItem.
As I understand it (and I coded it to test) if I try to use pAttribute again
by clearing with pAttribute.Clear because it is a shallow copy the
pItem is also cleared. I guess I need a "deep copy" but can't find
any documentation on it.

I was wondering if someone can help me with an web application design
problem. I have a aspx page which builds up an arraylist called addresses
and outputs the values in the arraylist items to a datagrid. I am using the
viewstate object to store the Arraylist items on the page on postback.
My PROBLEM is that I need to redirect the user to a new aspx page and on
this new page i need to be able to access the items in my arraylist. Is this...

I run into this situation all the time and I'm wondering what is the
most efficient way to handle this issue:
I'll be pulling data out of a data source and want to load the data
into an array so that I can preform complicated operations against
this data. The returned record count in these operations is always
variable.
1. I have been using an arraylist.add function to handle
non-multidemional returns but was wondering if I'm better...

From reading the documentation, this should be a relatively easy thing. I
have an arraylist of custom class instances which I want to search with
an"indexof" where I'm passing an instance if the class where only the
"searched" property has a value. I expected to get the index into the
arraylist where I could then get the entire class instance. However, the
'indexof' is never calling my overloaded, overrides Equals method. Here is

Hi All
I'm planing to write an application which allows users dynamically add
their points (say you can add upto 30,000) and then draw xy graph. Should I
use an array for my coordinate point storage and dynamically resize it when
there is a new point or should I use ArrayList? Is speed noticable between
the two?
Regards,

I am using VB.NET 2003 and a socket control to receive and sending data to
clients.
As I receive data in 1 thread, I put it into an arraylist, and then I remove
the data from arraylist and send it to the client.
Before adding data to the arraylist, I check if the depth of the arraylist
is longer than iMaxQueueDepth, and if it is, I clear the arraylist.
Is it possible that while I am clearing the arraylist, the ThreadMain at the
same time...

I've been reading about how C# passes ArrayLists as reference and Structs as
value, but I still can't get my program to work like I want it to.
Simple example:

Hello
My pgm1 (User Interface Level) passes an empty ArrayList to pgm2

the ArrayList.
Question1: When pgm2 gets the ArrayList back from pgm3 how to extract and
separate the fields out fo the ArrayLists?

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,...

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.
