Removing first index of an array

ORC
I have a large array where the first index must be removed, but how is the
best way to do that when the application must be optimized to speed?

Thanks

Use ArrayList or any other ICollection to implement your own override for
such class

I would suggest using the Queue class. An actual array would be very
slow as you'd have to copy all the elements each time you removed one -
and ArrayList would work the same way.

If Queue doesn't do exactly what you want, you can use my
RandomAccessQue ue from
http://www.pobox.com/~skeet/csharp/miscutil

Basically it's like an ArrayList with a circular buffer.

Hi,

An array may not be the best way to store the data if you have this
requirement.
You have two options:
1- Change the store method, using a Queue, an ArrayList or maybe a Stack (
if it's suitable for you )
2- If for some reason you need to use an array what you can do is use a var
to indicate the first index not used, in this way instead of using
array[0] you use array[FirstIndex] and update FirstIndex according.
You can do this a class too.
Cheers,

I have the following. There must be something less cumbersome without push pop. The function parameter obj is the event.srcElement and has the attributes(properties?) picNum and alb pinned to it. The function is part of a process to delete the selected obj, a photo in this case from the album vis albumArr. TIA Jimbo function Album(albumName) { this.name=albumName; this.paths=new Array(); }

Hi, I start a new thread about a discussion from yesterday (or for some of us this morning). It was a not so nice discussion about dynamically removing controls from a panel or what ever. It started by an example from me, that was far from complete and with typing errors, but basically it had the meaning to show that removing controls reversible was the nicest method. This was a lets say conclusion (but what is that in a newsgroup) in a...

Looking for suggestions on how to handle bad words that might get passed in through $_GET variables. My first thoughts included using str_replace() to strip out such content, but then one ends up looking for characters that wrap around the stripped characters and it ends up as a recursive ordeal that fails to identify a poorly constructed $_GET variable (when someone hand-types the item into the line and makes a simple typing error).

(VB'2003) What's the correct way to remove multiple, selected items from a ListView control (say, from a ContextMenu)? I ask because I'm getting a very annoying ArgumentOutOfRangeException because the ListView seems to be trying to "re-select" items that are no longer there! for example, giventhat I have 3 items in my list: Select the first and remove it - no problem.
