• How to read the value of the selected item in the DropDownList control?

  Hello

  The DropDownList component has a selectedItem property is supposed to return a ListBase.

  But what I want is just the 'chain' which is supposed to be the selected item in the DropDownList control.

  How to read this value?

  Thank you

  -Malena

  You are misreading the documentation. ListBase.selectedItem returns an object. This item comes directly from your data provider, so you just have to go up or go for any property you need.

  Hi Alex,

  Please find the code to work for your problem. I did it in Flex3... but you can do even in Flex4.

  Since it is just a function in your script. Check out the code below:

  How to disable scrolling on the right side of the mouse?
  It drives me crazy. Just want the cursor but cannot see anything in the control panel.

  This option you can find in the advanced options of the mouse.
  Control Panel > mouse properties > device settings and if you have Synaptics driver click on settings. You will find the option of virtual scrolling.

  Just remove the check mark in front of the horizontal and vertical scrolling options, and it will be OFF.

  Hmm, I did not forward. This is a new tab page with nothing to do with what you were dragging?

  I wonder if this might be a feature of one of your extensions. You can see their and disable/remove those that are not essential or unrecognized, here:

  Firefox orange (or the Tools menu) button > addons > Extensions category

  If you disable the extensions, usually a link will appear above at least one of them to restart Firefox. You can complete your work on the tab and click one of the links in the last step.

  If there is no difference, you could test mode without failure of Firefox - which is a standard diagnostic tool in order to avoid interference by extensions (and some custom settings). More info: questions to troubleshoot Firefox in Safe Mode.

  You can restart Firefox in Mode safe help

  In the dialog box, click on 'Start mode safe' (not Reset)

• How to identify items on the checklist 'Exceptions' in the firewall of Windows XP?

  I have 40 points listed on the 'Exceptions' list Windows XP firewall. Of those, there are 24 which can be easily identified as being for use with software installed and utility.  I have 14 items listed with a term somewhat vague, called 'Services '.  I checked the lists of these TCP ports on the internet and I found that 5 are called or classified as 'no '.  Others have names that do not match what I have installed on my computer. such as dynamic and/or Private Party, Synapse non HTTPS, NUTS Bootp Server instantiates zero - control messaging, CosmoCall Universe Communications Port 2, ATI Sharp logical engine, System DVT and SecureSight Event Logging Server Port.  The others are DCOM (135), UPnP infrastructure and they are often referred to a being obsolete, according to various sources online.
  It should be our responsibility as users of computers and/or administrators to use measures to protect our operating systems using programs antivirus and antispyware up-to-date and ensuring that our systems and other operating software are updated regularly.  Thing that many of us can forget how our firewall settings are configured, including which are checked on our firewall lists 'Exceptions '.  Sometimes, you may need to remove a list control item because the software to which it applies is no longer installed or when a reliable source online checks as a checklist item is obsolete and can be deleted safely.  Unfortunately, it is not enough on line information to correctly identify some of these Firewall Exceptions as course, still being in service and for the legitimate transfer information.  There are several Exceptions to the Services on my computer that will eventually be rechecked when Windows is restarted by two programs (svchost.exe and another that I have not yet identified). How do we identify each function as legitimate?
  We have a lot to deal with when we protect our information.  Spyware, virus, worms, Root Kits and even our own programs and settings can affect the safety of our computers.  He arrived at a point where we have to develop software better which will keep a record of each file is added, changed or removed from our operating systems, while they are carefully parsed for signs to be used as a form of Malware. Using antivirus and antispyware programs, alone may not be enough protection. Our firewall settings are equally important.  We can not simply block all exceptions in the firewall, because we need to have ports open for software, monitoring of maintenance programs, email and security programs.  The big problem is to identify who is who and what they are supposed to do when they are vaguely defined as 'Services' how to determine who is who, and that one can be deleted safely?

  Well,.

  If I were in your shoes, I wouldn't have kept all programs except the default (not same remote connection or sharing as I don't use them). For others he added as exceptions, I would have checked them on: Microsoft.com and msdn.microsoft.com. If the programs are associated with MS, you will always get an answer. If there is no answer or if I'm in doubt, I have it deletes from the list of exceptions.
  Finally, if any program is affected by this and creates the connection problem, I would have added it to the exceptions. Other, I would allow in Exceptions.
  THE RULE IS TO REFUSE ANY PROGRAM THAT YOU DO NOT KNOW, AND IF YOU HAVE ANY DOUBTS. IF YOU EXPERIENCE ANY PROGRAM, CREATE PROBLEMS, YOU CAN ALWAYS ADD IT LATER.

• Qosmio X 770 - 11 c - how to disable on board the speakers when you use Line Out?

  Hello

  Is it possible to disable on board to intervene when the output line is used.

  Currently, if I plug in a cable to the socket of hadphone and choose alignment on the realtek Control Panel, sound is output line out as expected, but also through the internal speakers.

  Is it possible to stop this and don't have sound out through the output line?

  Thank you

  Graeme

  If you want to hear his helmet only you should choose option helmet.
  Disconnect the cable and reconnect it. When you see the small window on the screen where you can choose between the headphones and output line options choose headphones and you'll hear on external display only.

  In case you have disabled this pop-up dialog box you can activate it manually. Open the Realtek Manager connect the external device and when you see active point black on the right side make double click here and change the settings.

• How can move items in the queue of 1 printer to another

  the title is the question... There are 2 printers put in place, just one, the disposable items in the queue and I want to move them.

  Jobs that are already in the queue are files that were produced by the printer driver and therefore include the printer controls that are specific to this printer.  Directing to the queue print on a second printer will only work if the second printer can correctly interpret the commands to the printer to be the first printer.

  If the second printer is of the same type as the first, the simplest method is to temporarily redirect the port assigned to the second printer.

  1. Go to printers and faxes
  2. Right-click on the icon for the 'good' printer and select Properties, then click the Ports tab
  3. Scroll the list of ports and make a note of the port to which the 'good' printer is made (one with a check) click on Cancel to close the Properties dialog box
  4. Right-click on the "disposable" printer icon, select Properties, and then click the Ports tab
  5. Make a note of the port which is checked, uncheck it and check the port that you noted in step 3.
  6. Click OK

  If the printers are not identical models, but at least the same type (laser, inkjet, matrix), it can work.  The closest to the printers are, it is likely that the print job prints correctly.

• How to disable access to the cd player while windows is locked.

  Hello

  Does anyone know it's possible to disable access to the cd/dvd drive while windows is locked?

  That is, I would like to press Ctrl + alt + delete to lock my pc, then while I'm away, someone presses the eject button on my cd player and it will not eject.

  I have looked in device, properties of D: drive management, security settings, etc., but have been unable to find such a control to this day.

  Any help on this is greatly appreciated.

  Kind regards

  J

  Hi JC_226,

  This isn't the Windows feature. Can not disable access to the cd player while windows is locked. However, there is an option to disable the CD/DVD device. To do this, you can follow these steps:
  a. Click Start, click Run, type devmgmt.msc, and then click ok.
  b. in the list of objects, expand CD/DVD players.
  c. right-click on the sub element and click on disable.
  d. follow the instructions in the wizard to disable the device.

  Important: If you disable a device that is required to start the system, such as your floppy drive or CD-ROM/DVD-ROM drive, these devices will not work, and your system might not start.
