Create Global Variable

Hello developers,
I need to create a global bind variable, which i can fill with a return value of a select statement. Can someone tell me how to do it, or send me a link, where global bind variables in APEX are explained

Hi,
Thanks for your information.
>
This works, when the condition of P0_END_TIME is "always", but doesn't work, hen it's "never".
>
Of course the conditional display for the other item will not work, if the conditional display for the P0_END_TIME is set as Never.
Do you want to hide the item P0_END_TIME on the page where the other item is displayed?
If yes set the conditional display as:
Condition Type: Current Page is NOT in Expression 1 OR Current Page is in Expression 1(Use the appropriate one! )
Expression 1: Comma delimited list of Page Numbers
OR
Do you want to hide the item P0_END_TIME for all the pages of the application?
Then set the item attributes for P0_END_TIME:
Display as: Hidden
Value Protected: No
Hope it helps!
Regards,
Kiran

Creating global variables

Hi,
I am searching for the best way to create global variables so that the script can work on all adobe reader versions . I tried gobal.varibaleName at the initialize event of the form, but it is only working in the earlier versions of designer. I tried using script variables, but it always initializes the variable to string value. I have wrote some functions on the script object, and every time any functions fails, a global variable count gets incremented. At the potsave event of the form if the count value is greater then 0 , a simple warning message is displayed . Now how to declare and initialize and increment this count variable so that the script can work on all the versions of adobe reader ?

You need to change your code little bit..
First,
All Global Variables are String Type. If you use a "+" sign to add a number it will treat the value as string and append at the end.
So if you want to do numerical calculations on the global variables first you need to convert them to the right type.
In the below code I am parsing the value to an Integer type first before I increment it.
Second,
You have created a variable of name "count" which could be a reserved name. Try to avoid the reserved names for variables. So I created a variable "intCount".
Third,
After incrementing value if you want to assign the value back to a Global variable you need to conver it to String type. (the opposite way like you did earlier in step 1 by converting String type to Integer)
var a = parseInt(intCount.value) + 1 ; //Step 1
intCount.value = a.toString(); //Step 2
var b = parseInt(intCount.value) + 1; //Step 3
intCount.value = b.toString(); //Step 4
Thanks

How do you reference a created global variable in a report text field?

I have created a parameter using the Globaldim statement in a script file. when I reference this parameter in any other script file during the current DIAdem session the value is passed without any issue. Call the variable parmxyz where I assign it a value of 25.3
The help section under Globaldim mentions that global variables can be referenced in all panels, scripts, and dialogue boxes. When I try to insert a text box on a report page using the @@parmxyz@@ it returns NOVALUE where I expect to see 25.3 (for example).
When I substitute @@CurrDate@@ I do get the date, so I know the text box is valid. What am I doing wrong?

Hello Steve!
It should work the way you did it. But their are some circumstances wich might prevent it:
You have reseted the global script engine. All variables will be lost.
You have a Sub with the same name in a command extension script. There is no warning ;-)
One Test you can make is to put in '@@TypeName(paramxy)@@' as the expression to see the variable type. You can also try a realy unique variable name. The last option is to use ItemInfoGet to get detailed infos about your variable.

Dynamically create (global) variables

Hi,
Is it in anyway possible to dynamically create variables, like you can do in Forms:
DEFAULT_VALUE('test', v_test);
with v_test holding the variable, like 'GLOBAL.TEST'. Forms would then create me the variable as it doesn't exist yet, assigning the given value.
Like this I could read my variables' names from a DB table, dynamically create them, and assign their values. Inside the report I would then use them as lexical references.
I know I can create parameters inside the report achieving the same, but we need the table-approach for our translations. Getting rid of the parameters' overhead would be great!
Any suggestions appreciated,
K.

Where the lov is attached set the VALIDATE FROM LIST property to YES and craate one trigger for each field called WHEN-VALIDATE-ITEM and use the code as below...
IF GET_ITEM_PROPERTY('FORM_FIELD_NAME',ITEM_IS_VALID)='FALSE' THEN
:FORM_FIELD_NAME:=:GLOBAL.EmpCode;
END IF;
Don't forget to set NULL for global variable in KEY-LISTVAL trigger after assigning value to the form's field.
HTH.

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

Global Variable in Package Specification

Hello,
I created global variable in package specification,
Is it valid for the current session or it will work for all the session.
Thanks,Kannan.K

Package varaibles are session bound, to demonstrate, a simple test:
--session 1:
SQL> select dt_test_pack.get_global from dual;
GET_GLOBAL
SQL> exec dt_test_pack.set_global(50);
PL/SQL procedure successfully completed.
SQL> select dt_test_pack.get_global from dual;
GET_GLOBAL
        50
--Session 2 at the same time
SQL> select dt_test_pack.get_global from dual;
GET_GLOBAL
SQL> exec dt_test_pack.set_global(100);
PL/SQL procedure successfully completed.
SQL> select dt_test_pack.get_global from dual;
GET_GLOBAL
       100
--Back to session 1:
SQL> exec dt_test_pack.set_global(null);
PL/SQL procedure successfully completed.
SQL> select dt_test_pack.get_global from dual;
GET_GLOBAL
--Back to session 2:
SQL> select dt_test_pack.get_global from dual;
GET_GLOBAL
       100HTH

Global Variable declaration in Custom Infotype

Hi All,
I need to validate a custom infotype field, where i need to check for execution times. I need to override the field value only during first time of the run(PAI logic) and there after user can choose a value of his choice.
I was looking out for Global variable to check if its first run. Can you please tell me how do i create global variable in custom infotype? The top include specified in the program is not editable, being standard (MPH5ATOP).
Thanks,

The system will generate an include with the naming convention ZP<Custom Infotype number>10(This program will be included in the custom infotype main program ZP<Customeinfty number>00). You can use this include for your data declarations.
Ex: if the number of the custom infotype is 9010 the generated include name will be ZP901010.

Global Variables in BI

Hi,
Can anyone explain me the steps to create global variables in BI with out using Query designer?
I do not have the infoobject in my cube but still I need a variable i.e for currency translation with out the need of adding the infoobject to the cube.
Thanks
Sri

Hi Sri,
You can create a bew variable in table RSZGLOBV. Also all variables used in BW Queries are global, i.e. not tied to any InfoProvider. You can use a variable created for a query on Cube A, in a query on cube B. The variables are attached to the InfoObjects (Char variables). There are other variables like formula variables which may not be attached to an InfoObject.
Hope this helps...

Declare global variable and retrive?

Hi,
we are working in live project in webtool, we wants to create global variable,
calling that variable in a required pages, our questions is that where to declare global variable and how to declare in which page we have to declare? pls guide us its very urgent and send the code.
Regards
Kannan.D
Edited by: kannan desikan on Jan 14, 2008 8:07 AM

Hi Kannan,
I would suggest using a comma delimied list or putting it in the database.
ArrayList myList = new ArrayList();
myList.Add("one");
myList.Add("two");
myList.Add("three");
string comma = "";
// store the array in the session state
foreach (string s in myList){
Session["persistedArray"] += comma + s;
comma = ",";
To get the array back
if (Session["persistedArray"] != null){
ArrayList myList = Session["persistedArray"].ToString().Split(new char[1] {','});
If your array is storing objects, you should use the database.

Global variable readonly

I chose to try/use a global variable to resolve a complex situation I was having. I followed the "Creating Global Variables" from LabVIEW help and everything seemed to work fine. The global stopped working, however, when I checked my files into CM and the xxxGlobal.vi (created by the global variable process) was readonly. I didn't see a runtime error, but the global always returned the default. Then, when I changed the file's attributes (enchecked readonly), I could exercise the other functionality.
Is this a known issue - do I have to make this global.vi read/write for all users, or is there another solution?

I don't think my conclusion (above) is correct. I had a case statement error that made it appear that the readonly was the issue, when it was not. I'm not sure what the deal is now. Here is what I did.
I placed a global variable(gv) in the block diagram of one VI, then double clicked on the gv and got a blank vi. I dropped a text control onto the front panel and named it ReportFormat. I then did a "save as" to save the new (global) VI. I then added some logic (where I originally dropped the gv) to populate the global variable with the user's selection from a drop down (two possible choices) . I then went to another VI and in its block diagram I did a "Select VI", found/selected this global.vi I just created. Since I only have one item on the front panel (in the global.vi), I received an association to ReportFormat. I did a "Change to Read" so I can use the string output to drive a case statement. The default case is always selected, though.

Programmatically select global variable object

Hello all.
I have a rookie question that may have an easy answer (or perhaps you can direct me to a different method which is fine too). I’m using a global variable in an instance where it’s controlled by a parent VI and read by multiple children VIs. The global variable contains Boolean switches, each with a specific name.
If possible, I’d like to make the ‘child VI’ more generic and programmatically flexible so that I don’t have unique children. That way, instead of four children, I just have one (makes debugging easier). Here’s the crux of my question: selecting which object is assigned to the global variable on the block diagram is done by clicking on it with the mouse – can I instead do that programmatically?
More specifically, when using the global in children VIs (as instructed in the “Creating Global Variables” section of the help files), you can select the global vi and add it to your block diagram. The next step is to select the front panel object to associate the placed variable with the proper data (you do this by mouse clicking the node you just created – see the attached image). My question is, can I select the object associated with the placed node programmatically instead of needing to mouse click on it?
Cheers!

There is a better way of doing this as the others have already pointed out.
Even Single Process Shared Variables with their API Interface would be better as Globals:
Using this VI to read the variables gives you the ability to reference them with a string (Link to Variable). You may have to add an additional variable in future versions of your code, where you just need to add the new variable to the project and pass the string to the VI without changing the code. Single Process Shared Variables are based on Global Variables, which are usually just a bit faster. Single Process Variables can easily be converted to network variables.
However, I agree with Damien that Data Value References would probably be the best sulution.
Btw, there is a good KB talking about Globals: Are LabVIEW Global Variables good or bad, and when is it ok to use them?

How do i create and pass a global variable from one vi to several sub-vi's?

Hi Guys,
I am trying to create a program that opens several front panels (sub-VI's) in sequence. in each front panel, the user would open a file that the name is obtained from the previous sub-VI. I would like to know how i could pass the filename and refnum of the file thorough from one sub-vi to another. A global variable would do it in VB, but how do we do global vars in LABWIEW. thanks
Papish

I put together a sample VI and Sub VI that illustrates how to pass a Refnum and access a data file while in a Sub VI.
For multiple VIs just repeat the sub VI process.
You probably don't wanna use a Global Variable if not needed (can add to the mess down the road haha).
Let me know if it helps you out! Or if I can clarify anything else!
Chances are if you have seen VI in the forest it hasn't fallen.

How to create a global variable in forms 6i

How to create a global variable in forms 6i

:GLOBAL.my_var := 15; Well, this statement is not correct! Global variables
stores a character string of up to 255 characters in
length. Thus, valid statement for Khurram example
is:
:GLOBAL.my_var := TO_CHAR(15);
or
:GLOBAL.my_var := '15';
But numeric values are implicitly converted by oracle so there's nothing in fact wrong with the statement...
:GLOBAL.my_var := 15;

What I want to do is to combine Get Voc/Isc and GO buttons (shown in the front panal) to one button, and also combine Setup Linear Stair Sweep and start sweep together. I do now find a good way to do that. Thanks so much for your kind help.
There is no "Get Voc/Isc" or "GO" button anywhere on the front panel, and I have no idea what you mean by "Setup Linear Stair Sweep" and "start sweep". Are you sure you uploaded the correct code?
Other VI comments:
You are abusing/misusing global variables.
You already have a state machine, so you can actually code this using just the state machine without actually needing the separate event structure loop. Even if you do keep it, that still does not require you to use global variables.
Why do you have a loop around the Write to Spreadsheet File? This serves no purpose and actually stops your code in that loop until the Stop global is set. This doesn't make much sense.
Since you do not have a path wired to the Write to Spreadheet File VI, you will be asked for a path each time the loop iterates. Use a shift register to hold the value of the path from iteration to iteration.
Get rid of the Build XY Graph Express VI and those Convert to Dynamic Data functions. Replace with a single Bundle function.

Business Rules : Unable to create a global variable (Fixed)

Hello all,
I try to create a global variable in order to use it in a business rule;
I selected an outline.
I chose the type "Member"
I chose the dimension "Period"
I clicked on the lookup button in front of the default value and chose the member "January"
Finally, I chose the usage type "Run-Time prompt" and type in a prompt string.
Unfortunately, when I click on save, I get an error message : Variable value ["January"] is invalid.
If I try to do not specified a default member, it is possible to save.
But when I launch the business rule and specified a member in the the prompt message, I get an error 1060120 : OLAP error.
I cannot figure out what's going wrong, so any help is welcomed.
Thanks,
DLP

Thanks for your answer,
I finally figure out what's going wrong.
This issue is due to the fact that the outline is configured to accept duplicated names.
When I create the same outline but with duplicated names turn off, every thing goes perfectly.
I don't know why the outline accepts duplicated name.
In fact, I do not understand what are the reasons for using duplicate name...
