• Can I access a variable form of function outside?

  I don't know much about ColdFusion yet. If I declare/cfset a variable inside a function, can I just access this variable directly from anywhere on the. CFM page?

  If you define a variable in a function without specify var then Yes, the variable will be accessible on a global scale.

• How to disconnect a network unidentified without internet access?

  My laptop running Windows 7 says I'm connected to a network not identified without internet access and allow me to connect to my wireless home connection, but there is no internet connection is.  The only way that I can use internet on my PC is if I connect my phone and use the internet tethering from there, (which sometimes is not recognized).

  Please help on how to disconnect a network not identified!

  Hello

  You can't disconnect from it.

  It's good because of the inability of the computer to connect to your network.

  It detects that there is something there, but it can connect to it.

  Assuming that it is wireless and the wireless router signal is strong, and it broadcasts its SSID (wireless network name).

  -------------------------

  These steps and tell us where is the breaking point.

  Check the Device Manager for the wireless card valid entry.

  http://www.ezlan.NET/Win7/net_dm.jpg

  If there is no valid entry, remove any entry from fake and re - install the drivers for the wireless card.

  Check network connections to make sure that you have a network icon/entry wireless connection, and that the properties of the icon (right-click on the icon) are correctly configured with the TCP/IPv4 protocol in the properties of network connections.

  http://www.ezlan.NET/Win7/net_connection_tcp.jpg

  ------------------

  The wireless card drivers much also install utility wireless of the seller.

  Make sure that if there are teas from Wireless Utility of seller does not work with the native Windows wireless utility (Service WLAN).

  ----------------

  Make sure you firewall No. preventing / blocks wireless components to join the network.

  Some 3rd party software firewall continue to block the same aspects it traffic Local, they are turned Off (disabled). If possible set up the firewall correctly, otherwise totally uninstall and get rid of its remaining processes that permit the own local network traffic flow.

  If the 3rd party software is uninstalled, or disables, make sure Windows native firewall is active .

  party like Hello and NetMagic 3rd network managers can block local traffic too.

  ---------------------------

  Stack TCP/IP work should look like.

  Right-click on the wireless network connection card, select status, details and see if she got an IP address and the rest of the settings.

  http://www.ezlan.NET/Win7/status-NIC.jpg

  Description is the data of the card making.

  The physical address is MAC of the card number.

  The xx must be a number between 0 and 255 (all xx even number).

  YY should be between 0 and 255

  ZZ should be between 0 and 255 (zz all the same number.)

  The date of the lease must be valid at the present time.

  * Note 1. IP that starts with 169.xxx.xxx.xxx isn't valid functional IP.

  * Note 2. There could be an IPv6 entries too. However, they are not functional for Internet or LAN traffic. They are necessary for Win 7 homegroup special configuration.

  ---------------------------------------------------

  A message in the small window that says connected wireless doesn't means that you are really a valid functional connection.

  Above everything is OK, you must be able to connect to the router.

  Connection to the router means that you can enter the IP of the router base in an address bar in one go, being able to connect and configure the router menus see.

  If it doesn't connect to the router, journal newspaper from any computer that can connect to the router wirelessly with a wire, disable wireless security, make sure that the wireless SSID broadcast is enabled and try to connect with no. wireless security.

  Enable security wireless after you eat to make a functional connection.

• With the help of Creative cloud on a desktop computer in a rural area without Internet access

  I have a subscription to creative cloud for my home office. I soon will participate in a photography workshop in a rural area with NO INTERNET ACCESS. I don't own a laptop and you carry my office instead, we remain. I know that the software is installed on the machine and I should be fine with its use without online access, rectification? I'm also right in thinking it will "not be considered" as being used on a second computer, because while I use it on this trip I won't have access to the Internet and so no IP address?

  Hello

  The only thing that could cause problem, is if your workshop is more than a month long. While using applications downloaded from creative cloud, internet access is necessary once a month for a routine license check. Here are some creative cloud FAQ:

  http://www.Adobe.com/products/creativecloud/FAQ.html

  Do I need a continuous Internet access to use my Creative Suite apps?

  Because your Creative Suite applications are installed directly on your computer, you will not have a continuous Internet connection to use on a daily basis. However, you need to be online when you install and license your software and at least once every 30 days thereafter. The software warns you when you connect to the Internet for a license status check.

  Note: If the product can not check your permit at the 30-day mark, a 7 days period. However, if you are not able to access the internet within 7 days, your applications will be blocked (Soucre: http://forums.adobe.com/message/4513667#4513667)

  As for your second question - as long as you use the same device that you already have your applications installed, you have always only a single device registered to your account.

  If you have any other questions, feel free to post here again.

• Get the value of the variable inside the function from the event (EventListener)

  How to get the value of the variable inside the function from the event. Variable has been declared as a function of external events.

  var StringVar="sample";
  
  
  
  
  myButton.addEventListener(MouseEvent.CLICK, myClickReaction);
  
  function myClickReaction (e:MouseEvent):void{
  StringVar="other sample";
  }
  
  trace(StringVar); /* it gives me "sample" value and i would get "other sample" value */ 
  

  This strange because if it would be the trace of a normal function would give me good result.

  var StringVar="sample";
  
  
  function myClickReaction():void{
  StringVar="other sample";
  }
  
  myClickReaction();
  trace(StringVar); /* it gives me result as i wanted to have - "other sample" value */ 
  

  I also know method of passing of arguments depending on the event, but it doesn't for me as I would like to

  var StringVar="sample";
  
  
  
  
  myButton.addEventListener(MouseEvent.CLICK, function(e:MouseEvent){ myClickReaction(e, StringVar) },false, 0, true);
  
  function myClickReaction (e:MouseEvent, StrVar:String):void{
  
  StrVar="other sample";
  }
  
  trace(StringVar); /* it also gives me "sample" value and i would get "other sample" value */ 
  

  How to do it correctly?

  I do not know the structure of your screen lists so I can't tell you how to access the variable, but you're on the right track. If it's a parent, then you can always use the .parent property to cross to the top the list display to try to access.

  for example 1 level:

  MovieClip (this.parent). StringVar = "another sample";

  Add more properties .parent to continue to move to the top of the list.

  for example:

  MovieClip (this.parent.parent). StringVar = "another sample";

  Just like always, use traces (MovieClip (this.parent). StringVar); until you get the value that you want to know that you're accessing them correctly.

• How to create network without internet access

  I have three devices: air mac, mini ipad and iphone OS. but I can't access the internet.

• Airport network guess without the access control list.

  In fact, on the page AirPort base stations: on the guest network feature, Apple write this:

  "If enabled, access control lists will be applied to both the main Wi - Fi network and the network of comments. If you use Access Control Lists, you will need to add your comments network clients to the list so that they can join. »

  I think that on previous versions of the airport, it was possible to use the network to guess without the access control list.

  The idea is that only the (primary) private network should use this access control list.

  The network presupposes that is give for direct and temporary access (not necessary to access Airport utility, ask your friend and note its Mac address, restart the resort from the airport... for every friend who invited you to home)!

  Is there a workaround resolution?

  Unless you have set up a default rule 'No access' in the timed access settings, then it is not necessary to set up a rule for each "guest." Just give them the password for the network of comments and they will be able to access the network.

  IF... you have set a default rule 'No access' in the timed access settings, then you must also configure a rule for each device that you want to allow to connect with the settings for the time that the device is allowed to access the network.

• How to change a global variable in a function?

  Hello

  I want to change a globalvariable in a function, as a first step I made in this way:

  class Global_output_class
  
  GlobalDim("Correlation_Status,fail_part,End_Exp")
  dim pouet
  
  Correlation_Status = 12
  Call Correlation()
  pouet = Correlation_Status
  
  Function Correlation()
    Dim Global_output_class_sub
    Set Global_output_class_sub = new Global_output_class
  
    Correlation_Status = 1
    fail_part = 2
    End_Exp = 3
  
    Global_output_class_sub.CorrelationStatus = Correlation_Status
    Global_output_class_sub.failpart = fail_part
    Global_output_class_sub.EndExp = End_Exp
    set Correlation = Global_output_class_sub
  End function
  

  In this case: correlation_status receives a value of 12, then I go to my correlationn() function where it became 1

  Then he comes out of the Sub-function and takes the previous value of the program (12) (I hate that)

  To solve the problem I did it this way:

  class Global_output_class
  public CorrelationStatus
  public failpart
  public EndExp
  end class 
  
  GlobalDim("Correlation_Status,fail_part,End_Exp")
  
  Correlation_Status = 12
  Set Global_Output = Correlation()
  Correlation_Status = Global_Output.CorrelationStatus
  fail_part = Global_Output.failpart
  End_Exp = Global_Output.EndExp
  pouet = Correlation_Status
  
  Function Correlation()
    Dim Global_output_class_sub
    Set Global_output_class_sub = new Global_output_class
  
    Correlation_Status = 1
    fail_part = 2
    End_Exp = 3
  
    Global_output_class_sub.CorrelationStatus = Correlation_Status
    Global_output_class_sub.failpart = fail_part
    Global_output_class_sub.EndExp = End_Exp
    set Correlation = Global_output_class_sub
  End function
  

  This way my global value are copied in themselves after leaving the subprogramme

  I had a lot of variables, is there an easier way for the global variable in a function of change keep the value after you leave the service?

  Thanks for the help,

  Fred

  Hi Fred,.

  It is possible to use a global variable defined, but the best way is to use a function call (or procedure call) with parameters. Please first find the right solution for a function call with parameter and the suboptimal way with a comprehensive valiable:

  dim oParameter
  set oParameter = new cGlobal_output_class
  
  oParameter.Correlation_Status = 12
  
  msgbox "Correlation_Status before Call Correlation: " & oParameter.Correlation_Status
  Call Correlation(oParameter)
  msgbox "Correlation_Status after Call Correlation: " & oParameter.Correlation_Status
  
  '-------------------------------------------------------------------------------
  Function Correlation(oPara)
    msgbox "Correlation_Status in the FUNCTION before change: " & oPara.Correlation_Status
    oPara.Correlation_Status = 1
    oPara.fail_part = 2
    oPara.End_Exp = 3
    msgbox "Correlation_Status in the FUNCTION after change: " & oPara.Correlation_Status
  End function
  
  '-------------------------------------------------------------------------------
  class cGlobal_output_class
    dim Correlation_Status,fail_part,End_Exp
  end class
  

  call GlobalDim("oPouet")
  
  dim oPouet
  set oPouet = new cGlobal_output_class
  
  oPouet.Correlation_Status = 12
  
  msgbox "Correlation_Status before Call Correlation: " & oPouet.Correlation_Status
  Call Correlation()
  msgbox "Correlation_Status before Call Correlation: " & oPouet.Correlation_Status
  
  '-------------------------------------------------------------------------------
  Function Correlation()
    msgbox "Correlation_Status in the FUNCTION before change: " & oPouet.Correlation_Status
    oPouet.Correlation_Status = 1
    oPouet.fail_part = 2
    oPouet.End_Exp = 3
    msgbox "Correlation_Status in the FUNCTION after change: " & oPouet.Correlation_Status
  End function
  
  '-------------------------------------------------------------------------------
  class cGlobal_output_class
    dim Correlation_Status,fail_part,End_Exp
  end class

• Variables in the function MathScript ode solver

  Hello

  I'm using LabView for awhile and I started using the text tools more. To solve a system of differential equations, there is this very elegant tool to do this in a MathScript node with the ode solve algorithms (for example, "ode_adams"). As the LabView help said, I've defined a function and registered as a ".m" file. I loaded this function in mathscript and solve differential equations.

  Both and so good, but my problem is that I can not all variables in the function. I can only put numbers in the function but not variables. Unfortunately I need to define the variables outside the function in the MathScript node.

  Does anyone have an idea how to manage the variables in this case?

  I have attatched a picture of the function and test VI (LV2014).
