• With the help of constant static as the FXML id

  Is it possible to use a constant static like the id in FXML and if so, how?
  
  For example if I have a Person class with a constant static set, such as:
  
  public static final String NAME = "name" field
  
  And then in a FXML file:
  
  <? import person? >
  < TextField id = Person.NAMEFIELD / >
  
  The code above FXML generates an error saying that "what exspected.
  I also tried with "$Person.NAMEFIELD", but this does not work either.
  
  Any suggestions?

  Is it possible to use a constant static like the id in FXML and if so, how?

  Yes, this is supported in JavaFX 2.2:

  The code above FXML generates an error saying that "what exspected.

  The quotes are required. FXML must be syntactically valid XML.

• Get a static reference to decoration

  Is it possible to get a static reference to a decoration? I have some tips that is represented by colorful decorations that I want to change the colors of them based on the data that I get. I know, it is possible to obtain references to the decorations in a programmatic manner, but it is something huge maintainability because it is incredibly difficult to follow the course of the program. Thank you.

  I don't think you can get that directly. Check the exchange of ideas. I think that there has been a few proposals along this line.

  Perhaps another approach would be to put indicators of color behind the decorations box and change the color of those. The borders of your pipe decorations would be opaque, while the Interior would be transparent to allow the squares of color to show through. The color boxes appear as standard terminals on the block diagram. With appropriate labels, they fit perfectly in the paradigm of data flow.

• How to get the name of a class private data controls?

  How can I get the names of the controls within a class private data?

  I use the framework of the actor and try to create a tha method will be executed when run the actor. This method should an o list all names of control inside the data class to find the initial value within a configuration file (config.ini file), the key to the configuration file will be the name of the control.

  Thank you.

  You already do the substitution method just because you write for the bundle by name.  And then how are you going to respond to all types of data might be the key.  You do more difficult things that it takes to really very few benefits.

• Get the default value for class LV 1498 error

  I call get the Default Value.vi LV class to dynamically load a class.

  It was working fine until I added Open Config Data.vi to read an .ini file.

  The application works fine when I press the button RUN in the LabView development environment, but when I create the executable file with Application Builder and then run it, I get:

  "1498 error occurred getting class LV Default Value.vi"

  Possible reasons:

  LabVIEW: Library has errors. Correct the errors before performing this operation.

  «"" "String of full appeal:»»"»

  Download LV class by default Value.vi

  Test.VI

  LabVIEW has tried to load the class in this path:

  g:\cal\devices\Digital300Meter\Digital300Meter.lvclass

  I narrowed the problem down to open Config Data.vi included in the application, not in the class. I don't have to call the Open Data of Config vi to get this error.

  I have a Subvi, called "SelectDevice" which refers to Open Data from Config. In my main Test.vi SelectDevice is in the true case of a true/false case structure, which is set to False.

  If I put a design schema off around the Open Data of Config vi, I do not get the error.

  I suspect that including Open Config Data include a VI in the application that interferes with the LV ranks by default.

  Thank you, it works!

  I also put the additional Exclusions page as follows:

  Disconnect the type definitions - verified

  Remove unused polymorphic instances of VI - verified

  Remove unused libraries project - members verified

  Change the project library file after removing unused members - unaudited

• I get constant attention that my Vista is not valid. How can I turn it back on it?

  How to re-enable

  I turned off my ADSL router and it made my phone freeze and not be able to restart again. Send in repair and store PC has managed to recover the Vista, although a lot, a lot of my data has been corrupted and could not be recovered. In addition to this, I get a constant attention that my Vista is not longer valid. Vista was already installed when I got my laptop two years ago and I don't remember how I got it registered last time even though I know I did. I do not have a CD with it and don't know where to find key "reg".

  I'm worried that I will be thrown completely after some time has elapsed. I have lost so muc htime on this incident everything and can not afford another disaster. MS will be able to give me the information of the previous time, I registered?

  You can reactivate your Windows Vista installation by doing the following:

  1. click on the Start button and in the box, type search: slui.exe 4

  2. press the Enter key on your keyboard.

  3. Select your country.

  4. follow the instructions for the activation of the telephone (toll-free).

  NOTE: When you call this number, you will first hear an automated voice. If the automated voice gives you an option to talk to a
  Live the Rep of Activation, select this option. If this is not the case, do not enter all the numbers. This should force the automated voice transfer
  an Activation Rep. Live trying to activate through the automated voice won't work, in your case, only through the Live Activation Rep
  your activation will be successful.

• Variable static in a class bug?

  Hi guys. I try to keep a number of objects of a class with the static count variable.

  When I try to compile with 'public static int count' it gives the compiler errors "reference to undefined"Box::count"for the two cases where the number is incremented and decremented

  Strangely, it compiles perfectly if I use only "int count" without the keyword 'static'... but it's not useful to me.

  Here is my code... can someone tell me where I have gone wrong?

  #include
  using namespace std;

  Box class
  {
  public:
  public static int count;
  Box()
  {
  Count ++;
  } //compiler survey "refers to the undefined"Box::count"here
  ~ Box()
  {
  County;
  } //compiler survey "refers to the undefined"Box::count"here
  };

  int main (int argc, char * argv)
  {
  Area B1;
  fprintf (stderr, "Hello");
  return 0;
  }

  Welcome on the support forums.

  You must initialize the static variable
  you access the variable with Box::count

• Cannot get internet static IP address

  Hi, I put several new Win7 PC in an office that replace Win XP PC. I need to use static IP addresses on all of the PCs, as it is required to access the Unix server. Start of the new PC with internet access very well, but when I assign static IP addresses, they have more internet. My IP address, DNS server, gateway, etc. are all correct and identical to what is plugged into the PC XP (except IP address of course). Even if the new PC do not have internet access, they can connect with the Unix server and other PCs on the working group. When I diagnose the problem I get the answer: "your computer seems to be configured correctly, but the device or resource (DNS server) is not responding." All the XP computers using the static IP address and have the internet very well. Yes, I already tried to clear the DNS cache.
