Use variables that are defined later on

Hi Guys!
I'm having some troubles trying to figure out how to use or call a variable that I define later on a website, for example
<cfoutput>#meta#</cfoutput>
<cfset meta=1>
The real case is that meta is being used by other functions and since it's already there I want to take advantage of it and recycle, so how can I call or use a variable that where I want to use It, it hasn't been declare yet?

This is a very very fundamental question about how programming & web apps are concerned, so best you read some docs:

I want to delete a lot of things childrens stories, albums which are not used which that are on my ipad. However when I go through Itunes it wont show me most of the stuff in my library. it takes ages to delete one at a time.
Can you help please?

Thanks King_Penguin for taking time to read and reply.
I just purchased this movie on Thursday, May 15, so just a few days ago. I have never had any trouble whatsoever since I have been in Vietnam. I have downloaded several movies and even music and they have all synced to my respected Apple products except for this purchase.
Sorry, I don't quite understand what you mean by studios and different versions. Could you please explain?
I checked my purchased list in my purchase history under my account and there are no hidden items.

Unable To Reserve Lots that are Expiring Later on the Current Date

    Hi Guru's,
       An item has an expiry date of 12-APR-2015 23:59:59.But it got expired, from 12-APR-2015 00:00:00 the lot shows an (Available To Reserve) ATR as 0 on the Onhand Availability , although the onhand quantity and Available To Transact (ATT) show the quantity.As per expiration date expiration of lots should starts from the date stamped on it and the timestamp doesn't really play a role.
Seen the note: Unable To Reserve Lots that are Expiring Later on the Current Date through Auto Detailing get Error of Could not Query Reservations (Doc ID 1193423.1).
    But the solution provided is confusing, as in a R12.1.3 inventory implemented environment we cannot find the options to set picking rules with Lot --> Exp Date >= Expression --> Trunc(sysdate).It would be great if any body can let me know the solution.
Rgds,
Sri.

Hello,
InContext Editing does no longer support HTTP authentication method, as the release notes state. As a result, users will not be able to edit sites, folder or pages that are password protected.
Currently we do not have a workaround for this issue and we recommend removing the password protection. The issue has been added on our feature list but we do not have a proposed timeframe to fix it.
Thank you,

Check if in Word document (Word 2013) advanced option "Use fonts that are stored on the printer" is set

Is it possible in a VBA macro to check whether an opened word document has the advanced option "Use fonts that are stored on the Printer" is set.
I have a word macro that opens and processes thousands of word documents. The processing needs to be different based on whether this option is set or not.
Thanks,
Harry Spier

Hi Harry,
I'm afraid that we're not able to retrieve this option value. The Advanced Options are actually stored as application level. Some of the options can be accessed with the Word.Application.Options property. But there're also many options that are not
exposed in the Word Object Model. As you can see in this figure, there's no property corresponding to "Use fonts that are stored on the printer":

Using a Meter control in LV Touch Panel, and using shared variables that are custom controls.

I Just started using LV touch Panel module with an NI TPC-2106.
I have two differenct problems:
1) I was planning on using the "Meter" control quite a bit. I can set up the meter exactly how I like on the host PC, but on the touch Panel computer it seems to ignore my adjustments, mainly the start and end of the scale - i.e. I would like control to run from 0 to 360 with 0 straight up, using the entire circle. However, on the Touch panel computer it always puts 0 at about 7 o'clock and 360 at about 5 o'clock. I have also tried adding markers to no avail.
2) I am communicating with a compact fieldpoint controller. I can creat a shared variable that is a simple double with no problems. However, I have some shared variables that use a custom control for the variable type - bascially a cluster with a couble doubles, a time stamp, and an enumeration. It lets me drag the shared variable into my diagram, but it seems to ignore it when I run it.

Ipshita_C,
- I am using LV 8.6.1f1and LV Touch Panel 8.6.1.
- I have attached a simplified VI that shows how I want to use the meter. Notice that the placement of the endpoitns does not work correctly on the touch panel, and that it ignores the arbitrary markers that I placed.
- I also have included an XY graph control that displays on the TPC with margins around the graph area that I removed from the graph control.
- For the shared variable, it appears to be an issue related to the touch panel, not fieldpoint. I found another thread in this forum that mentioned that clusters containing Enumerations do not work in shared variables on the touch panel. I changed the enumeration to an integer and it now works fine.
In general, there seem to be a disappointing number of limitations in the touch panel implementation. My biggest concern is that I have not found any documentation from NI that lists these limitations. I seem to have to try things out and see what works and what does not work. Can you point me to a comprehensive list of touch panel modules limitations?

When to use Tables, which are defined as u0093No Objectu0094?

Generally, in which situations should we use a <b>no object type</b> table ? Theres not much explanation about that type in help files.

Hello,
the possibility to define a type for table is new with version 2004. Before, all the table where defined as "no Object type"
"No Object Type" tables are tables not used in UDO (User Defined Object). They are the "defaut type" table in Business one, You can access to them using the UserTables object, select/insert/remove/update record using this object
If you choose ono of the available object type (master data, master data line....) theses table are created as UDO tables.

Why we use variables what are the advantages of variables

hi
can u tell me why we use variables and where we use variables
ashwin

hi Ashwin!
Variable are used for providing the parameters for a query at real time. that means we can dynamicall specify some what exalty the query should display in the query for example we can use a variable on the charectersitic like country so that we can decide the contents of the query to will be relavent to the countries we specified.
Advantages of using the varibles in a query are
1) we can build a single query which can be used by all. Ex:we can generate a report for all the customers seperatly by using a single query and just by changing the value in the variable at runtime
2) if we use the processing type authorization for a variable. We can limit the user from accessing the information which he is not authorised to see in the report. This will also make us personalize the query based on the user who is accessing the report.
Sap help on overview and usage and the types are given in the following link:
http://help.sap.com/saphelp_nw04/helpdata/en/f1/0a56a7e09411d2acb90000e829fbfe/frameset.htm
hope it helps.

Can I set a Session Variable from a Dashboard Prompt, using values that are

Hi All
Trying to set a Session Variable to an integer value, by letting users select a text value from the drop-down list on a Dashboard Prompt. The goal is to set the input parameter to the IndexCol function, but to provide the end users with a text description of what they are setting.
Select Value Set Variable Value
My 0
My Team 1
My Companies 2
My Teams Companies 3
Any suggestions on how to accomplish this? Certainly we could populate the drop-down from a data source, however I don't see how to populate a variable with something other than the values on the screen.
The IndexCol function is referenced in a Filter in Answers, and I'm thinking to populate a Session variable using the (Presentation) variable value set from the prompt. But how to do this? I see a reference to a function NQSSetSessionValue(), but cannot find documentation on how it works.
Any clue will be greatly appreciated.
Thanks

Hi kishore..
Looks like the link u have sent uses advanced SQL tab to set session variables. I want to know if I can use "set variable NQ_SESSION.myvar= @something" in the "SQL results" -while creating a dashboard prompt-.
Purpose: I want the session variable to be set based on whatever report that im currently in.
And i dont want to use presentation variables because im using a reset button in my page.
My reset script resets presentation variables and NOT session variables.
Thanks in advance

Change public variables that are used in another class to private variables

Hi
I have public variables in one class and I am also using them in another class the only thing is all my variables are supposed to be private. When I change then to private then I cannot use them in the other class. Please someone help me.
Thanks
D

First way - make variables protected an you can access them from any class within package or from any class that extends class with variables.
Second - make variables private and create public get/set methods for that variables for accessing they from any other class/package.(That's preferable way).
I have public variables in one class and I am also
using them in another class the only thing is all my
variables are supposed to be private. When I change

Can I read/write global variables that are in other PC?

I attach the vis and the executables.
My problem is that when I run( continuosly, because in other way, I read the default value of the variable) getvalue.vi and setvalue.vi, I don´t have any problem, I can read/write the global variables, the two vis is running in the same PC.
But when I do the exe and I run them continuosly , it doesn´t work.
Any solution?
Thanks in advanced!
Graci

Hello Bichillo,
By running the vis continuously you are running into race conditions. If you cannot control when you are writing to or reading from a global variable, you cannot know whether the value writen/read is the right one or not.
In your case the global variable value that is read is sometimes the last value writen and sometimes an empty string.
To make the global variable behave as desired, that is, keeping its last value, the global variable must be in memory when you access it using VI Server. If it is not in memory, the returned value is an empty string. That´s why you sometimes get a non-empty string: when you access the global variable to read its value, it happens to be in memory because you´ve just writen to it.
To ensure that the global
variable is always in memory and it keeps its last value, you must include the global variable into your block diagram. I am attaching modified vis that implement this.
Hope it helps.

Setting global variable that are static but I want them to change

I'm trying to set a global variable so I can let the user change the state in the Plugin Manager. I've created a checkbox (in PluginManager.lua)
f:checkbox {
title = 'Show HTTP response',
value = _G.showHttpResponse,
that references the global variable (in PluginInit.lua)
_G.showHttpResponse = true
The state of the checkbox accurately reflects the initial value as set. Everything seems fine but after unchecking the checkbox, the value is always true in my plugin. I expected _G.showHttpResponse to change to reflect the setting in the checkbox.
What have I overlooked? Is this only for setting static globals?
Abe

Reading the Lightroom SDK manual seemed to indicate that using globals would be the way to go. I'm thinking that it is only appropriate for static text.
I've taken both your suggestions and have used the plugin preferences. I didn't think you could get and set them in the Plugin Manager but they work just fine. Now I set my debug flags in the plugin manager screen and they are available to the plugin and are persisted as well.
Thanks for the suggestion. Everything is working.

Query time affected when using dimensions that are at a lower grain

Hi all,
I have a product dimension that has one hierarchy and 7 levels: All Product -> Category -> BU -> Class -> Department -> SubDept -> Item. The lowest level has about 8 million members. The Department level has about 1500 members
Some of my Cubes are actually mapped to fact tables where the grain is at Department level. So I've ensured that in the Cube Mappings Editor, the Department Id of the fact table is mapped to the Department level of the Product Dimension, and I can actually see in the Cube's Aggmap, it is using LOAD_STATUS to limit the Product dimension to the Department level members for the aggregation.
Querying the Cube using SQL brings back the correct result across different level combination, however the query constantly takes about 2 - 3 mins to complete.
As a test, I've built another dimension that goes down to the Department level only, and issue the same query against the Cube. The difference is significant as the query takes roughly less than 1 second to complete, and returns exactly the same result.
Any idea? I am using AWM 11.2.0.1.0A
Thanks

The stats you posted are puzzling. Usually the sum of loop and fetch time is close to the total time, but there is a big missing chunk of time in your case. It is clearly related to the calculated measures, since removing them solves the problem.
The most common problem with calculated measures is that they can cause the cube to loop densely (i.e. all logical member combinations) instead of sparsely (i.e. only the member combinations that have data). But I don't think this is the problem in your case since the difference between rows_read and rows_returned is small
ROWS_READ 212ROWS_RETURNED 185
NULLTRACK_SUPPRESSED 27>
If dense looping has happened then the rows_read is often orders of magnitude greater than rows_returned. You can see the looping strategy by running
select value || ' : ' || details as loop from cube_operations_log where name = 'LOOP_OPTIMIZED'Here is an example of the output for a good (sparse) loop.
LOOP
ON : LOOP AGGMAP(PRICE_COST_CUBE_SOLVE_AGGMAP PRICE_COST_CUBE_PRT_TEMPLATE)Here is the output if I add a year to date calc to the cube.
LOOP
ON : LOOP UNION(AGGMAP(PRICE_COST_CUBE_SOLVE_AGGMAP PRICE_COST_CUBE_PRT_TEMPLATE
) AGGMAP(DENSE(TIME) PRICE_COST_CUBE_SOLVE_AGGMAP PRICE_COST_CUBE_PRT_TEMPLATE))Note that TIME is now looped densely, but the code is still trying to loop the other dimensions sparsely. Finally, here is the loop if I add a random olap dml calculation to the cube.
LOOP
DISABLED :There is now no optimized looping and the cube will be looped densely.
So it may be worth checking the loop descriptor for your fast and slow cases, but my best guess at the moment is that the performance gap has something to do with your specific calculations. If I were you I would add them back one at a time to see if you can find a particular measure, or type of measure, that is causing the slowdown.

How can I view my photos in "Events" like in iPhoto? How can I create events? I have 55,000 photos and 1700 events so the only way I can possibly manage my photos is using events that are one slide in size.

I have 55,000 images organized into about 1700 events. The only reasonable way to view my library is using events in iPhoto where each event has one image That still leaves 1700 images to sort through but that is a lot easier than 55,000 images. In the side bar is a folder with "iPhoto Events" but those views still show all of the slides. How can I create events and view my photos as events as in iPhoto? Events are critical for large libraries and has been my primary way to sort images.
Thanks!

I had a problem a couple of months ago when iPhotos suddenly rearranged the order of my Events (Why won't iPhoto let me arrange my photos?) . I was told "Use albums not events - events are not a good way to organize - albums and folder are designed for organisation and are very flexible".
Haha! I should have paid attention and read between the lines! My iPhotos were highly organised groupings - not according to date but the way I wanted them - and it was so easy to do! I see now that if I had them all in albums, as per the Apple Apologist suggestion, I wouldn't have this unholy mess I have been left with just to make iPhone & iCloud users happy. I am now going through Photos and making Albums (of what used to be in my Events) ... maybe I'll get this finished before they do another non user friendly update!

How can I add 2 variables that are entered via input text/number type

So I have created 2 text fields via composition ready
$("<input type='text' value='' name='input1' id='input1' size='5'>").appendTo("#Stage");
sym.$("#input1").css({"position":"absolute","top":"70px", "left":"52px"});
$("<input type='text' value='' name='input2' id='input2' size='5'>").appendTo("#Stage");
sym.$("#input2").css({"position":"absolute","top":"90px", "left":"52px"});
input1 AND input2.
The user then puts a number in each field.
I have a 3rd field created to hold the answer. I also made a text field with the name "scorefield" to see if that would work, either will do.
Then on a button on the stage, the user clicks on it to add those first two numbers together and have the sum appear in the 3rd field or the text field that has the symbol name "scorefield".
However I can not seem to be able to add the 2 values of the text fields. On the submit button I have:
var number1 = $("#input1").val();
var number2 = $("#input2").val();
var additionresult = number1 + number2;
sym.$('scorefield').html(additionresult);
answer1.value = additionresult;
The problem is that it is NOT adding number1 and number2 together!
If I substitute + for - or / or * it works using those symbols, but if I try to use the plus sign and add the two, it does not work and instead physically adds the numbers next to eachtoher.
So If I were to put a 5 in field one, and a 2 in field 2, the result comes out to be 52...instead of adding the two values, it places them next to eachother.
I know those ARE numeric values because any other mathamatical sign works. I can multiplay, subtract and divide those two numbers. I can even check to se if its higher or lower of a value using > or <.
But when I use the + sign, it breaks.
Is there some other sign I must use to add two values?

Sorry I forgot to change the string to a integer earlier. Here it is corrected.
file here: https://app.box.com/s/mulkhd1rlyyafovqc3od
var input1 = sym.$("input1")
input1.html("number1: ");
userInput1 = $('<input />').attr({'type':'text', 'value':'', 'id':'input1'});
userInput1 .css ('font-size', 28);
userInput1 .css ('width', 50);
userInput1 .appendTo(input1);
var input2 = sym.$("input2")
input2.html("number2: ");
userInput2 = $('<input />').attr({'type':'text', 'value':'', 'id':'input2'});
userInput2 .css ('font-size', 28);
userInput2 .css ('width', 50);
userInput2 .appendTo(input2);
sym.$('btn').click(function(){
var number1= userInput1.attr('value');
var number2= userInput2.attr('value');
var Numone = parseFloat(number1);
var Numtwo = parseFloat(number2);
var answer = Numone + Numtwo;
sym.$('result').html(answer);

RegisterOutParam doesn't recognize types that are defined between quotes.

Suppose one defines a type as below:
create or replace type "VectorOfInt" as varray(300) of number(10);
in the C++ program, when using statement -> registerOutParam (...), the fourth argument is the type.
If one passes ... registerOutParam(..., "MYSCHEMA.\"VectorOfInt\""), that is, escaping the type name between double quotes, to indicate that the case should be respected, doesn't work. Everywhere else this construct seems to work fine.
If, however, one defines:
create or replace type VectorOfInt as varray(300) of number(10);
and one passes... registerOutParam (...,"MYSCHEMA.VECTOROFINT"), that works fine.
Is that a bug... or am I misunderstanding the concepts?

Shaun,
Don't know if this is the problem or not, but I had the same thing happen and my problem was that I had signed in to one device with my @mac.com address and the other device with my @me.com address. Both were recognized by Apple & I never got any errors (I only have one Apple ID account), but my data would never sync. Once I signed in with the same addy on both, it worked fine.

Use variables that are defined later on
