Is there a performance advantage to parsing thru a recordset verus using an
array?
I'm currently trying to populate a listbox by returning data from my
database, then either parsing thru the recordset until I reach the EOF, or
putting the data into an array.
Thanks for your assistance.

Ok, I'm quite a newbie, so this question may appear silly. I'm using
g++ 3.3.x.
I had been taught that an array isn't a lot different from a pointer
(in fact you can use the pointer arithmetics to "browse" it). So I
expected that when I run this program, I get both c1.A and c2.A
pointing to the same address, and changing c1.A means that also c2.A
changes too.

Hi,
I am trying to read in a list of data from a file. Each line has a string in
its first column. This is what i want to read. I could start by saying
char to read in 1000 lines to the array( i think!!).
But I want to use malloc. Each string is at most 50 characters long, and
there may be zero to thousands of lines. How do I actually start the array?
I have seen char **array etc. At first I tried char *array but I think
that gives 50...

All this time I was under the illusion that I understand the concept of
multi-dimensional arrays well ---- however the following code snippet
belies my understanding.
I had assumed all along that a declaration like:
int intArray
means that there is an array of pointers to int with a size of 5, each
of whose elements is an array of int with a size of 3.
This definition seemed intuitive to me since a declaration like

I looked at the addresses in an 'array<>' during debug and noticed that the
addresses were contiguous. Is this guaranteed, or just something it does if
it can?

If The size of the array is unknown during programming time then how is
such array declared??
Suppose there is an Array named arrClashname(size unknown at start),
Now when the clash occurs I want to store that name into the
arrClashname,
Therez a do while loop inside which has some conditions which decied
when clash occurs and a variable named Clash is set to true and its

Hi, ppl
Somebody knows why this works in MSIE6 and not in MSIE7 :

artPage=new Array();
artPage=null;

I've read the msdn doc about IEnumerable. It seems to me that
IEnumerable objects are essentially wrapped-up arrays. It simply gives
us the foreach convenience. Is this correct?

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,...
