How do I make 3 variables global throughout????

I want to be able to access them in the functions getInput and printToFile
I want to make the following 3 stacks global:
Stack headOutput = new Stack ();
Stack bodyOutput = new Stack ();
Stack footOutput = new Stack ();
I want to put them in this program:
import java.io.*;
import java.lang.*;
import java.util.*;
public class Assemble
     public static void main(String args[]) throws IOException
          if (args.length > 0) //     Checks to see if there are any arguments
               printArgumentInfo ();
          else // if no arguments run the program
               getInput ();
               printToFile ();
}

it compiles.. but.. i get what is below when the program runs.. if i make the stack's static.. then i can't add to them.. isn't that the reason?... i need those 3 stacks to go through the functions getInput and printToFile and those are static methods...
Exception in thread "main" java.util.EmptyStackException
at java.util.Stack.peek(Stack.java:82)
at java.util.Stack.pop(Stack.java:64)
at Assemble.printToFile(Assemble.java:183)
at Assemble.main(Assemble.java:29)

How can I make a global change so all controls and indicators labels on the front panel change to another colour?

How can I make a global change so all controls and indicators labels on the front panel change to another colour?
I need to change the front panel so that it can be used in a dark environment.

Hi
The only way I see, is to use the "Controls[]" property and iterate through all of them. But don't forget about nested elements (i.e. clusters, tab-controls, ...).

How do I make preferences global?

This Oomph looks interesting but quite complex! I'm using eclipse for C/C++, and I have a custom code formatting style, and a custom syntax coloring style I use. In previous versions of eclipse I had to export both of those, and then import them in every workspace which is a bit of a pain.
So I imported the .epf and the formatting .xml files in Mars, and when I create a new workspace, my custom settings are not there. I do have the preferences recorder turned on. How do I make my syntax coloring, and code formatting work across workspaces without having to import them each time?

Moses,
Certainly there are a number of things we might consider adding as
features, e.g., drag and drop of an *.epf file might convert them to
preference tasks. Being able to record preferences into something other
than your user.setup, e.g., a project setup. Some ability to
selectively record the current setting of preferences as preference
tasks, much like the Eclipse's existing preference exporter (which is
very poor at being selective, so one often must literally paw through
the XML to remove unwanted things).
Think about which specific things would be very helpful, open
enhancement requests for them, and consider contributing something
towards those ends.

How to use a variable global?

Oracle 10g Enterprise edition
Is there a way to retain a text in a global variable session specific?
The global variable is declared in a package specification. But i am losing the values as the session changes.
Can any one suggest me an approach to go with this?
Thanks
R

No you didn't do anything wrong.
Web applications are inherently stateless, so create a new session for each database request. Oracle's Application Express, which is a web based application, implements a form of state persistency through it's own means of storing values. It does this by allocating a session ID to the user as they start up their connection to the application and then that session ID is passed as part of the URL to each page call, which allows the Application Express "engine" on the database to identify the session and pull back any variables that require persistency.
Sounds like you need to implement something similar.

How do I make a global color change in Flash CS5?

I am a rank Flash newbie, so maybe I'm missing something obvious. In InDesign or Illustrator, if I want to change every red object to blue, I can go into the color list, edit the red color to the blue values, and every instance of red in the document reflects the edit. I don't have to select each red element and pick the new blue for stroke and/or fill. I can't find how to do that in Flash, yet it's hard for me to believe that that capability is lacking. Help please!

i don't think there is such a setting in flash.

How do I make variables from CS.INI available to task sequences?

So I have created some custom variables in customsettings.ini under the 'Properties' area. These variables seem to be working in WinPE, but once I reboot and start to install Windows, the variables aren't listed.
I also don't see them listed in the BDD.log (if they should be there).
What am I doing wrong?

You need to also add the custom variables to the "\Scripts\ZTIGather.xml" file. As it is what tells the ZTIGather script to look for in the CS.ini.

How do I make a global helper servlet for all applications?

I am running about five different web applications in tomcat 5.0.24. They all need to do some spelling correction from time to time. I have a spelling correction API and a bunch of dictionaries, etc. so I can do it just fine. The problem is, I don't want each application to create all the dictionaries because then I end up with five spell checking programs and five dictionaries being accessed (basically I am exactly repeating myself five times and I start running out of memory). I would like to have a servlet that just sits waiting all the time and which any other servlet or JSP in any of my web applications can quickly dash of a spell check request to at any time.
How do I do this?
I think I need to write a servlet since I want to run it in tomcat and access it from my webapps, but it might not need to be a servlet since it is never actually contacted from a browser and will not ever write anything back to the client. I just need my other servlets and JSPs to access the spell checking functionality from time to time.

I'd say tomcat/common/lib is a good guess for where you'd put the class's jar file, but I don't use Tomcat so I can't say for sure. As for how to only have one dictionary, you need a singleton class, i.e. one that only permits one instance of the class to be created. Like this, if you haven't heard of it:public class SpellChecker {
// create a single SpellChecker here:
private SpellChecker theInstance = new SpellChecker();
// don't let anybody else create another one:
private SpellChecker() {}
// provide a method for returning the single instance:
public static SpellChecker getInstance() {
return theInstance;
// remaining methods go here
// watch out for synchronization issues
}To get hold of the spell-checker, just doSpellChecker.getInstance()PC²

How to make a variable global to use in all of my cfm page?

I have a problem with the variables.
i need to use a variable " loginrecord" in all of my cfm pages, its created in my login.cfm and the value of this needed in other page and maybe i need to change it .
in ASP simply we can use SESSION to make a variable global , is there any way in coldfusion ?
also in ASP we have a command SESSION.SESSIONID , so return the unique number from browser and we can se it as a security check for each one of people login to our site and each one is seperate random and unique number , is there any similar in coldfusion ?
Thanks
Alireza

Thanks,
the reason at the moment i stock with this command is i need to have login information available in all the pages to check the security. the good point i had in ASP is SESSION.SESSIONID , it make a unique number base on browser and i can check it if user loged in or no , or if loged in is the same user or other user . i couldnt find same command in coldfusion , and now i use <cflogin> but if i can find the way to have a browser session it help me in other part of my program.
i start coldfusion new ( near a month ) i have some book and Lynda DVDs, also online sources , and in this priod i re developed one of my program from ASP to coldfusion and its work. i am happy of this and help me to develop better and faster . in compare the coldfusion developed one realy is 40% original development in size and 50% faster . i have good background of ASP in last 8 years include MCSD and developed many program for a small and big companies. but i wanna to continue with coldfusion because i found it more helpfull than ASP specialy in FLASH development .
BTW thanks for your help

How do I make a variable path in AppleScript?

I'm mass distributing an application, and for the next update I want to add customization. My application currently make a folder in the "Documents" folder. The folder is called "MCL_CONFIG". What I need to do is make a unicode text file in "MCL_CONFIG". Since it's going to be used on many different computers the path to where I'm making the new file has to change depending on the user. How can I make a variable path to a non-directory? Here's the section of my code with the problem:
tell application "Finder"
    if folder MCLConfig exists then
    else
        display dialog "Welcome to Mc Launcher! You will only recieve this message once, unless you delete the MCL_CONFIG folder." buttons {"Ok"} default button 1
        make new folder at New_User with properties {name:"MCL_CONFIG"}
    end if
end tell
It's not shown but I set the variable MCLCONFIG to (path to documents folder from user domain) & "MCL_CONFIG" as text.
As a side note how do I make the code look like it does in applescript, here?

You can do something like:
set supportFolder to ((path to application support from user domain) as text)
set appName to "My Spiffy App"
set subFolder to "MCL_CONFIG"
tell application "Finder" -- add application support folders if needed
if not (exists folder (supportFolder & appName)) then
    make new folder at folder supportFolder with properties {name:appName}
    make new folder at result with properties {name:subFolder}
end if
end tell
Edit: it is recommended that the folder in Application Support be named with your application's bundle identifier, but most just use the application name.

How to auto create a global variable with specific variable name in a global vi ?

how to auto create a global variable with specific variable name in a global vi using lv ? Because i need to add a lot of global variable in this global vi. But you know, if i manually add them , it will be a much time-costing work. So i want to use someway to auto generate ? Can i ?? Thanks a lot !

Hi
what aartjan is saying is the way for you. but you can develop an utility which will actually help you create global variables. To get the details on this just have a look at VI Scripting section on LAVA forum.
But i would like you to suggest few things
1. If your programs have so many global variables (Thats why u want utility) then you should take out some time to read about LabVIEW design patterns. I think if programmer follows these practicess he dont need a single global variable.
2. Their are some other ways to achieve similar functionality as of global variables (Uninitialized Shift Registers, Single Element Qs and so on) but they are much faster than global variables.
I am Attaching Whatever Resources i am having I will also attach the template of the design pattern i generaly use in short duration

How can we deinitialize the global variable........?

how can we deinitialize the global variable........?

It would possibly be more performant to...
DBMS_SESSION.MODIFY_PACKAGE_STATE (DBMS_SESSION.REINITIALIZE);
Bearing in mind that reinitialize is not exactly the same thing as deinitialize ;-)

How can i make a CHECK in an ALTER table, to compare 2 Variables of TWO different tab

I have 3 tables:
EVALUATION (No_expert, No_article)
EXPERT (No_expert, origine, name)
AUTHOR_ARTICLE (No_Article, Code_author)
AUTHOR (Code_author, Name, Original)
and my question is: How can i make a check to refuse each time an EXPERT ADDED to the EVALUATION table. If this one is an AUTHOR, in other words, the EVALUATION.No_expert must <> than AUTHOR.Code_author.
This is what i did but it doesn't work:
ALTER TABLE EVALUATION ADD CONSTRAINT No_expert
CHECK (EVALUATION.No_expert <> AUTHOR_ARTICLE.Code_author);
thank a lot

BEX Query variant - how to make it Global ?

We have a problem that we did not have in 3.x. In NW04s, when some one saves a query variant, it can be seen/accessed only by that person. We have a need to make it global so that other users in the division can use the variant to run the query. Does anybody know to make this work?
I looked at the table RSRPARAMETRIZA and the field PERSONAL is always set to 'X' for variants created in BEX (using new BEX tool). We tried to blank this out (for testing) to see if the variant becomes global. But it did not help, in fact after this change whenever I choose this variant it kicks me out and I have to login again.
Any input/workaround is appreciated.
Regards
-Bala

As of NetWeaver 2004s variants (created in the BI70 runtime) are stored as an XML string inside of the table RSRPARAMETRIZA. In BW3.5 and before they were stored along with ABAP variants within the table VARI.
