advisable to remove and reassign the listeners to button
Hello
I'm trying to delete and then reassign a MouseEvent.CLICK to a step on the button, using the step button for 1 second.
When the first button is released, it works very well, but what 2nd is published, 1 a MouseEvent should be cleared and be given a second listenner.
what I'm missing here?
code example
bt_ok.addEventListener (MouseEvent.CLICK, log_in);
bt_pesquisa.addEventListener (MouseEvent.CLICK, pesquisar);
//
function log_in(e:MouseEvent) {}
var BTN = getChildByName ("bt_pesquisa");
{if (BTN.hasEventListener (MouseEvent.Click))}
trace ("exist um listener activo");
If (btn.removeEventListener (MouseEvent.CLICK, pesquisar)) {}
trace ("1 remocao");
btn.addEventListener (MouseEvent.CLICK, pesquisar_2)
} else {}
trace ("not removed");
}
}
}
Thanks for help

removeEventListener returns an empty and not a Boolean... so you can not do the if(!...) "check.
If you need to perform a sanity check, then you can removeEventListener first and check if it exists before adding the new event.
Right now, we just have to trust that the current callback method is deleted by the runtime Flash
This code works...
function log_in(e:MouseEvent) {}
var btn = getChildByName ("bt_pesquisa");
btn.removeEventListener (MouseEvent.CLICK, pesquisar)
If (! btn.hasEventListener (MouseEvent.CLICK))
{
trace ("add a new event listener");
btn.addEventListener (MouseEvent.CLICK, pesquisar_2);
}
on the other
{
trace ("remove current event has failed");
}
}

Want desolde/resolder, remove and replace the two damaged usb2 ports
I have a Sat A30 perfect by all means other than 2 USB2 ports on the back that are damaged (black plastic seperaters between connectors jumped) not quite sure why this happened because I was simply unplug the connected usb plugs on both occasions.
The connectors were not especially tight. fault is I have no insulation between copper connectors which are still found in the slots and causes a short circuit, when I plug in a usb device.
I bought a card mother relpacement (damaged) and usb2 connections are OK! Have good technician experience in carring out Soldering/desoldering and has all the tools. Problem is that I have not the slightest idea what connections under the Board of Directors are required to unsolder my damaged usb2 card in order to remove/swop and perform the necessary replacement.
I'm sure I'll be advised to contact an authorized reseller of Tosh. I tried this and they say that they will be already only the motherboard together and the cost is horrible. I would rather make the repair myself that's not rocket science.
The techies out there who could counsel with picture of the relevent pins to desoldering in order to remove and repair the fault would be greatly appreciated.
E-mail: [email protected]
If you can help in any way or point me in the right direction to go repair.
I hope someone can help. Thank you very much
StewartHello
Please don't be crazy about me, but in my opinion, is not a very good idea to open the notebook alone if you don't have a lot of experience with it. Laptops are designed on the specific way and exchange of material is not so easy as the exchange of material to work stations.
Believe me that a small error in the assembly/disassembly procedure can case damage to equipment or the façade of the same laptop parts. I know that there's not much service partner assistance because they want to do. It costs money, but you must understand that if they give that kind of advice or information they may close the shop very soon.
You can try to do it alone, but at your own risk and be careful.

Removing and installing the RAM several times can affect to my Mac Mini?
My little brother back RAM on my Mac Mini many times; but it remove the RAM properly and install it correctly
Removing and installing the RAM may affect to my Mac Mini?
Mac Mini (late 2012)
OS X 10.11.5
No, it should not affect the machine when the withdrawal/re-installing memory - correctly.
My second thought about this - why it has removed/re-installed memory several times? Trying to upgrade the drive? change a component any? repair?
Materials only I 'played' were - SSD, adding second HARD drive disk with data doubling cable, insulating modular wifi/bluetooth, etc. and of course, the upgrade memory. Once they did that, I got very little intention of reopening the mini - except air jet, clean the fan.

You can restore the factory state after an iTunes backup

Can I remove and reinstall the font without records book?
On my MacBook Pro 10.6.8 FontBook operates as a two-bob watch - do not let me access policies in Freehand MX that are definitely in the font book, among other things. The operating system used on 10.6.3 and I upgraded to 10.6.8 via a Mac/PC independent shop, so I have no 10.6.8 discs (I have the original 10.6.3 discs).
Is it possible to throw the font book in the trash and the re - download online? Or I can reinstall it from my 10.6.3 drive...?
Thanks in advance!
To clarify, there was never a 10.6.8 released on record as an installable OS. You install 10.6.3 (the last version released of the snow leopard), then apply the 10.6.8 Combo Update.
What you see, is very typical of a corrupted font book database. Replace the app does nothing to remedy.
Follow 1 a or 1 b depending on the version of Mac OS X you have. If you can't find the com.apple.FontRegistry file in your user account preferences folder, then it is easier to use 1A rather than trying to dig through several hidden files.
1 a) restart your Mac and immediately press and hold the SHIFT key when you hear the startup chime for a safe boot. Now keep the SHIFT key until OS X asking you to sign in (you will get this screen on a Safe Mode boot, even if your Mac automatically connect). Let the Mac has finished boot to the desktop and then restart it normally. You can release the SHIFT key right here. Yosemite is a little different. Whether a boot Safe Mode or a regular, you get the same progress bar. It takes just as long to reach the office in Mode safe. Then hold the SHIFT key until you get to the desktop. This will delete the font book database and cache files for the account you logged in Mode safe. Restart again normally.
1 (b) for a period of time, the font book database file, com.apple.FontRegistry, was buried deep in the private/var/folders/.../-Caches-/ folder. In later versions of Mac OS X, it is much easier to remove. Quit the font book. Open the Preferences folder in your user account, put the com.apple.FontRegistry file in the trash and restart. More fast than method 1 where you will need to restart twice. If you are using Snow Leopard, use 1 a method because this file is located in the private hidden folder.
Leopard or an earlier version, font sets, that you have created will be gone. In addition, all the fonts in the main three folders of fonts (System, library, your user account) will now be active, regardless of their status beforehand. In Snow Leopard, your games will remain intact.
