Array.length changes not really after the item deleted?

Frame 1, I loaded 9 clips (pieces of a chart) and their names of the instance (piece1, exhibit2 etc.) are in a table, arrPieces.   In 3, I'm trying to remove them, but I discovered that I had a problem with my while loop.   I removed the loop and discovered that the problem is really that the size of the array does not reduce after that I deleted an item.   I could not find it in the documentation.  Is this true?  I do not suspect.

That's what I've stripped the code in frame 3 down for:

trace (arrPieces.Length);     9 as planned
var whichPiece = Math.floor (Math.random () * 9) + 1;
arrPieces.splice(whichPiece,1);
trace (whichPiece);   as expected
trace (arrPieces);   as expected
trace (arrPieces.Length);   still gives 9 - should not
Stop();

Something obvious, I suppose, but I can't.   Help appreciated.

I don't know what you've changed things in, but you can still get the random index duplicate values, though that if you are splicing to the table, then it should not matter.

I don't know what else is going on in your code, or if you really need to remove the elements in the array, but you might consider randomizing just the array and then read through it, from 0 to 8.

  • Delete buttons do not work after the update of 10.11.16.

    Delete buttons do not work after the update of 10.11.16.  The delete button works if I pointed out and then delete, but not if I use the "back" button or try a removal of uniqueness.  It is a problem in all applications.  I tried it in textedit, search google chrome, safari search and find finder engine.  There seems to be a 'problem' of the keyboard' as far as I know nothing happened to my keyboard, IE the spilt coffee, that recent warming has been updated to 10.11.16.  I use an iMac (27-inch, late 2009) with i5 clocked at 2.66 GHz, running OS X El Capitan.

    Any suggestion would be appreciated.

  • My apple pencil does not work after the 9.3.4 update.

    My apple pencil does not work after the 9.3.4 update. I tried to restart but still does not work. Tried to forget the device and whenever I connect the pencil to the ipad pro, it is said that it does not recognize the cable / device. Help please.

    Greetings RechargeableJam,

    Welcome to the communities of Apple Support!

    I see that your Apple pencil does not work after update to iOS 9.3.4. I guess it's about to have a problem with something that worked with the previous version of the iOS software. I'm happy to help you to help you find the best resolution.

    First of all, let's close open applications on your iPad Pro. This can ensure that there is nothing running in the background that is causing a conflict. The following article will help you:

    Force a nearby application on your iPhone, iPad or iPod touch

    Then connect the pencil of Apple and see if it is recognized for the time being. If you don't see the Pair button, wait a minute while your Apple pencil costs. Then disconnect your Apple pencil, Plug and back on hold until you see the button in hand.

    Best regards.

  • Firefox does not open after the update. Cannot open the profile technical, even when you use the directory in cmd line path

    I'm using Firefox on a Windows 7 computer. Firefox does not open after the last update. I read the help articles and it seems that I need to create a new profile because my settings were probably corrupted. I'm unable to open the profile technical, even when you use the directory in cmd line path. I tried the following commands in the command line:

    Firefox Pei

    Nothing happens with every order.

    I am also running Norton Internet Security. I read a help of virtual navigation features Re article that can cause a problem. The article says to check the setting of virtualization in the internet security software and to clear the virtual cache. I went through all the menus of settings in Norton Internet Security version 21.6.0.32 and I don't see anything that looked like in "virtualization" settings, so I guess that does not apply to me. "

    There seems to be a bit of a problem past, especially with older models of iPad 2. Some people have reported success after that restore their device via iTunes, for others that it has not worked and all they get is a message "bring it in an apple store.

    Since it affects a lot of people, I think it's safe to say that the problem lies in the range of Apple. But I don't think it is recognized or no matter what put forward fix.

    You can try to restore your device, or you may just be stuck waiting to see if a fix comes out.

    More information: two bricks iMacs were late 2013 models.  A 21 "and a 27.  We have just updated a test iMac which was a late model 2012 using the 10.11.4 combo updater.

    Fix unexpectedly closes or problems of launch in iTunes for Windows - Apple Support

    Solution, according to this link, is:

    If the problem does not occur in Mode safe, remove any third party plug-ins iTunes: solving problems with third party plug-ins - Support Apple iTunes but the link has been archived, and I can't find any plug-ins installed iTunes. Any other ideas?

    For general advice, see troubleshooting problems with iTunes for Windows updates.

    The steps described in the second case are a guide to remove everything related to iTunes and then rebuild what is often a good starting point, unless the symptoms indicate a more specific approach.

    Review the other boxes and other support documents list to the bottom of the page, in case one of them applies.

    More information area has direct links with the current and recent buildings if you have problems to download, must revert to an older version or want to try the version of iTunes for Windows (64-bit-for old video cards) as a workaround for problems with installation or operation, or compatibility with QuickTime software or a third party.

    Backups of your library and device should be affected by these measures but there are links to backup and recovery advice there.

  • Computer does not start after the screen of the bios, Compaq Presario SR1023WM

    Ok. Trying to fix a friend's computer and seem to have met a strange barrier.

    Problem: The computer does not start after the bios screen.

    Details: When you turn on the computer, the compaq logo with intel inside is and has the < F1 Setup > and < F10 System Recovery > options listed as well.  And that's it as far as the computer becomes.  After that the computer just locked up, no work of buttons on the keyboard lights keyboard ect ect.  I tried the puree on the F1 key, as soon as I turn on the computer and I can handle so he can say * entering setup * but it freezes again after this point.  I already tried to eliminate the possible sources of the problem, removed all expansion cards, HDD and Dvd Rom module only disconnected, only memory (256 MB ddr 2700), power, vga and keyboard connected.  Ive also used the jumper on the motherboard to clear the cmos, hoping that would solve the problem without success.  I tried using a different memory stick and different memory as well...  Tried to use both a ps2 and a usb keyboard... Ive even tried pulling the rider for the protection of the bios password (even if she did not have a password on it, just try everything I can think of).

    The installed bios version is 3.1, and that's all that I know on the computer at this point, except that the website tells me to him.

    I'm basically at a loss on this one, so if someone feels scroll line-by-line of their brains on this one, I'd be very happy.

    I have a pretty strong understanding of computer repair, so feel free to give me something to try.

    If you need more information out of me, let me know as well.

    Try to clear the CMOS again but this time remove CMOS battery and hold the power button on a few seconds. Replace the battery, then try to start back to the top.
