Programmatically get names of all cases in a case structure

Hi All,
I have a subVI that is a state diagram (controlling some test equipment), with many states (i.e. each "state" is a case of a case structure), a text string chooses the case. All cases are named.
Within this subVI is it possible for me to programmatically retrieve the text name for each case of this case structure? I wish to be able to retrieve these strings so that the main VI will only be able to call valid states.
I have error handling to ensure that if an invalid state is called (by using the default case) that an error will be returned to my main vi, yet I would prefer to be able to retrieve the string to prevent any typo's etc.
Not sure if I've explained this well.
Thanks,

Solved!
Go to Solution.

You can do it with LabVIEW scripting, however, I wouldn't leave scripting in a final application. Use a typedef enum if you don't want to worry about this. If you want to keep it as a string (remember, this is a heavily debated subject) just make sure you test all cases before making it an executable and that should suffice. If you want to check to make sure it's a valid string, this seems like a bit overkill on the error checking! Just work it out when testing, or again as was said above, use a typedef enum.

How to get names of all Windows in a Form Application at runtime

Dear All,
I want to get the name of all windows in a form module programatically at run time. How to get it?
Any help or comments will be highly appreciated.
Thanks in Advance.

Hi Francois Degrelle,
First of all thanks for the response.
What if I have no items on a content canvas? In my application, I am using content canvas to hold the Image banner and help text of the current form, having no items at all. I am also using tab canvases to hold all items of form. The tabs are displayed on the content canvas at run time. So the tab canvases acts like frames (In my case).
Now if I am looping through items, it gives me the list of all of the tab canvases. Whereas the tab canvas always has no window assigned, as it is displayed on content canvas which has that Window which I need. Thus I am unable to get the names of windows in my case through the above stated procedure.
Another option could be if I can get the name of the content canvas upon which the given tab canvas is displayed?
Any way to do this or some other way to achieve the use case?
Any help will be highly appreciated.
Thanks in advance

List of inks can be obtained from Document.inkList and iterate through each ink to find whether InkInfo.printingStatus is set to "ENABLEINK"
here is the script
mydoc = app.activeDocument;
mydocTotalInkList = mydoc.inkList
mydocUsedInkList = new Array ();
j =0;
for (i=0;i<mydocTotalInkList.length;i++)
    if(mydocTotalInkList[i].inkInfo.printingStatus=="InkPrintStatus.ENABLEINK")
       mydocUsedInkList[j] = mydocTotalInkList[i].name;
       j++;

Getting names of all files in a directory.

import java.io.*;
import java.util.*;
public class dir{
     public static void main(String args[]) throws IOException{
          //BufferedReader in = new BufferedReader(new FileReader(args[0]));
          PrintWriter out = new PrintWriter(new FileWriter("dir.txt"));
          File file = new File(args[0]);
          //FileFilter filefilter = "log";
          Vector x = new Vector();
          int vlength;
          x = getDirectoryContent(file);//,filefilter);
          vlength = x.size();
          for(int i=0;i<x.size();i++){
               out.println(x.elementAt(i));
          out.close();
     public static Vector getDirectoryContent(File file){//, FileFilter fileFilter){
          Vector v= new Vector();
          if (file.isDirectory()) {
               File[] content = file.listFiles();//fileFilter);
               for (int i=0; i<content.length; i++){
                    v.addElement(content);
               }//for
          }//is directory
          return v;
     }//getDirectoryContent
That is the code that I am using, what I am trying to do with it is read all the files in a directory. So I can open them and calculate all the data in all of the files at the same time.
These are the file names that are in the directory when I run the program.
L0519013.log
L0331001.log
I have the code out put the file names in a file called dir.txt
after running the program this is what I get in the output file.
[Ljava.io.File;@70ccc4b2
[Ljava.io.File;@70ccc4b2
[Ljava.io.File;@70ccc4b2
Any clue waht this means?
also I am passing in the director as args[0]

if possible as well...
I could not get the FileFilter to work, could not get the syntax down to get it to work when I was initializing it so for the moment it is remed out. all files in the given directory will be of type .log so there really is no need for the FileFilter. But any help on how to include that in the code would be greatly helpful.
Thankxs

Programmatically get name of object?

Is it possible to call a method on a object to get the name of that object---the variable name, not the name of its class?
Example:
Person fred = new Person();
Person barney = new Person();
List names = new ArrayList();
names.add(fred);
names.add(barney);
for (Object o : names) {
     System.out.println(o.methodThatGivesObjectName()); // should print "fred" and "barney"
     //...print out other info about the object...
}It seems like this should be possible, but maybe it's not. BTW, I know I could add a "name" field in this example, but I actually want to do this with other objects, like arrays.
Thanks,
Gregory

What if you add the following code before putting the objects in the list?
Person wilma = fred;
Person betty = barney;You've now got two variables pointing to each object. Which one is the object's "name" and why?
And if you add this code after adding to the list but before printing
Person tmp = fred;
fred = barney;
barney = tmp;Now fred and barney have swapped which object each points to. What are the "names" of the objects now, and why?

You can get names of all controls and of all indicators. Use Get All Controls method of VI server.
This is not exactly that you want but may be will help you.

How can I get IP and hots names of all the machines.....

I need to get the IP addresses and host names of all the machines in my netowrk and need to select only is a HP / Compaq x86 machines finaly.
If you know atleast a part of this please help me.
[email protected]

You coulduse the broadcast address (x.x.x.255) in an ICMP sweep to determine which hosts are alive (and accepting ICMP).
But no, there's not a single (and definitive / sure) way to retrieve all IP addresses.

Getting the names of all classes

Hi,
I want to write a Java editor with code completion. Is there a way to get all the class names available in the installed Java run time environment.
Does the reflection API provides a way to do it.
Thanks a lot,
Chamal.

You can also look at JPDA (should be documented as part of your JDK under 'Tool Support' of the documents index), and the JDI api VirtualMachine.allClasses() method.
That will return the name of all loaded classes, which will not be the same as all classes on the path, as it includes any dynamically created classes, and excludes any classes on the path not loaded.
