Need to reenumerate Vector after removing element(s)?

Hi,
I'm using a Vector to hold a collection of Hashtables, and periodically I call a cleanup routine on the Vector as the contents change quite frequently. My question is: after I enumerate the Vector in order to walk through its contents to remove any Hashtables that are no longer needed, if I remove a hashtable do I need to reenumerate the Vector? Or will the removal of the Hashtable not affect the enumeration indices?
Pseudo-Code example.....
Vector v;
Enumeration e = v.elements();
while(e.hasMoreElements()){
Hashtable h = (Hashtable)e.nextElement();
if(h needs to be removed){
v.remove(h);
Any help is greatly appreciated.

yes, the Vector needs to be reenumerated, but a better approach is to not use Vectors for a collection that frequently changes.

Is it possible to rearrange the elements in a List after removing indexes?

Hello,
I am hoping someone can help me out w/a question.
I have a list
List<String> Labels = new ArrayList<String> ();and I add 3 elements in the list
labels.add("one"); //index 0
labels.add("two"); //index 1
labels.add("three"); //index 2Later on in the program I remove 2 indexes,
labels.remove(0);
labels.remove(2);When i try to iterate through labels it throws
Exception in thread "AWT-EventQueue-0" java.lang.IndexOutOfBoundsException: Index: 1, Size: 1I perfectly understand the error. My question is this: after removing the indexes, how can i rearrange the list so that the one element that is left (currently at index 1) is set at index 0 so that it doesn't throw an exception ? is this doable ?
Thanks very much for your help!!

This doesn't work!
Before those call the List looks like this:
[one, two, three].
After you call remove(0), it will look like this:
[two, three]
Now, when you try to call remove(2), it will throw an IndexOutOfBoundsException, as there is nothing at index 2 anymore.
I perfectly understand the error. My question is this: after removing the indexes, how can i rearrange the list so that the one element that is left (currently at index 1) is set at index 0 so that it doesn't throw an exception ? is this doable ?I'm afraid you don't understand the error message correctly, since then your question would be different.
The error message says "you tried to access something at index 1, but this list only is of size 1". This means that the only valid index at that moment is 0.

Deactivate "insert element before / remove element" in array

Hello guys.
It is possible to deacitvate "insert element before / remove element" function appears after right-click on a array in the frontpanel?
"Description and Tip" should stay.
Thank you.
Alex
Solved!
Go to Solution.

You can customize the right-click shortcut menu to remove some application items and keep others:
Right-click on the array (and not on the array element!) in the front panel and select Advanced->Run-Time Shortcut Menu->Edit...
This brings up the Shortcut Menu Editor:
Change the drop-down control from "Default" to "Custom".
Select the "???" line in the tree control on the left.
on the right, change the Item Type from "User Item" to "Application Item -> Description and Tip..."
It will automatically fill in the corrent Name and Tag.
Save the rtm either into its own file or into the control.
LV will automatically handle application items in the control, no event case needed.
I sometimes find the "Copy entire menu" function of the shortcut menu pretty useful if I only want to disable a few items.

I have installed elements 11. should i remove elements 8.

i have installed photoshop elements 11. is it safe to remove elements 8?

yes.
to install an upgrade, you need either the serial number of the upgraded program or, the upgraded program needs to be installed.
in either case, the upgraded program does not need to be installed after the upgrade completes installation.

HELP! I need to be able to remove power from a PXI chassis and replace a card without rebooting the whole system

I do not have particulars on the controller, but I am sure it's an NI chassis
and NI regular controller that has a serial cable leading back to the PC.
I am making this PXI rack into a debug rack for instrument cards,
so I need to be able to remove power from just the PXI chassis
and then replace the card with another one
or the same one and then turn the power back on and restart a
diagnostic test on the card WITHOUT
having to reboot the PC.
Is there a PCIe bridge setup that would allow me to do this?
Is there software that I need that can accomplish this?

Yes
The Chassi is a NI PXI 1045
and the controller is a NI-PXI-8331
Let me re-enumerate my requirements:
Background:
I have a number of NI cards as well as other manufactured cards in the system.
One of these cards in the NI system is considered to be a UUT.
That is, I am using the NI card cage system and other cards in the system to test a CARD
during a manufacturing test of said UUT CARD.
The UUT uses a PLX 9030 for it's PCI interfacing.
This UUT is not designed for hot swap, and I do not bieleve it is plug and play.
Requirement:
1. I need to be able to shut off the chassis and remove the UUT when the test finishes, replace the tested UUT
with a unknown UUT, re-apply power and then test the new UUT WITHOUT having to reboot the PC.
I have tried several things, such as disabling the PCIe busses in the windows control panel, and then removing power
replacing the UUT with the next one, re-applying chassis power and then re-enabling the bus and SOMETIMES it works.
I need a very robust way to do this.
I also bought a CHROMA PXI-52906-E extender card with bus switches on it, so that I can remove power to the UUT
without shutting off the chassis. The card is supposedley designed so that when power is re-applied to the UUT, the necessary
signals to boot the PXI PCI interface is conducted, but I think something else has to be written to the card's PCI registers.
I am by no means an expert in PCI/PXI,
but I seem to have exhausted all of my reserach online in how to meet my requirements.
Perhaps there is a way for the NI8331 controller to capture PCI configuration data to the card's on system boot,
and then "replay it" to my UUT after I re-apply power to the UUT?
Or perhaps PLX makes such a tool?
Any ideas?

Is there a way to remove elements from an array 1 by 1?

I have an two arrays, and they vary in size depending on a parameter set by the user (both arrays are the same size though, they both can vary in length). What I need to do, is remove elements one by one from the array, and use these as indices for another array. Basically, I built two arrays to store x-values on a graph. At the first value on the first array, I want y values on the graph to move from 0 to Y (any value). Then on the first value on the second array, I want the y values to move back from Y to 0 (creating a pulse, essentially, from the first value on the first array and the first value on the second array). By having each x value act as an indice for the y array, I belive I can acc
omplish this (ie, y =0 up to indice 90, then y = 5, then at indice 100, y goes back to equaling 0). I know this is poorly phrased, but it's difficult to explain. If anyone could help me out, I'd really appreciate it.

jdaltonnal,
Note: to add an attachment based on your comment of 6/12/01 to my earlier reply, I had to go back to this 'answer' mode, which gives me the option of adding attachments.
Per your comment, you have a sequence, so I've added a simple sequence structure and the 2nd array to provide a 250ms delay between each array output. Let me know...Doug

Hi, My photo stream used to work fine. But after removing all the photos to separate folders in my computer, my new photos are no longer streaming to my PC. They appear in the photo stream on my other devices - iPhone5 and iPad Mini. It's just my PC

Hi,
My photo stream used to work fine. But after removing all the photos to separate folders in my computer, my new photos are no longer streaming to my PC. They appear in the photo stream on my other devices - iPhone5 and iPad Mini. It's just my PC that's missing the photos.
When I open the iCloud control panel, I cannot turn on the photos. That option is ghosted. I'm running on Windows 7 with iCloud 3.0. Any ideas on how I can fix this? All help is appreciated! Thanks!

I need to uninstall downloaded version of Elements 12 on a computer, then install Elements 12 on the same computer directly from a disk. Elements 11 was previously used on same computer, and the albums and library had been moved to the first installation

I need to uninstall downloaded version of Elements 12 on a computer, then install Elements 12 on the same computer directly from a disk. Elements 11 was previously used on same computer, and the albums and library had been moved to the first installation of 12, which I am removing. How do I correctly unstall the old Elements 12, and install the new elements 12 from disk, and retain all albums and libraries from the old Elements 12?

You're welcome. It was not an answer, it was a question, and it could lead to being helpful if you explain why you think you need to uninstall.
As far as uninstalling goes, you will uninstall it like you do for any program, which depends on what kind of operating system you have. If you wish to retain albums and whatnot, maybe the following link can provide some guidance.

Use back up and restore from the Organizer menu. You are permitted two activations so no real need to deactivate the old copy unless you have installed it previously on another machine.

Need to take the N-th element from a queue

hello everyone!
I have a problem, i don't know how to take ony one element from a queue...
Indeed, i need to take only the 3rd element of a queue but i don't know how to do that... so i though maybe i can change it as an array (with the vi "flush queue") and then take the 3rd element of this new array but same problem, i don't know how to manage that!
please help me, i have been trying to solve this problem all day long
thank you very much!
Yanis

I am not sure if there is a more elegant solution but what I have done in the past in similar situations was to get all elements of the queue with the queue status. Then I would flush the queue and pop any elements I wanted back on the queue while removing the items I needed/wanted. As I say, this is not the most elegant but it is a tried and true method. If your elements are fairly small and you don't have lots of elements on the queue the performance hit is not too terrible.
