Use lpad function in local variable definition

Hi
I want to define a variable with lpad function applied to a data field. For example C_CHECK_NUMBER is the data field. I want to left pad the field with 0's to make it 6 digits long and store it in a variable. Something like this
<?variable@incontext:PADDED_CHECK_NUM;xdofx:lpad(C_CHECK_NUMBER,6,’0’)?>
<xsl:variable xdofo:ctx="incontext" name="PADDED_CHECK_NUM" select="xdoxslt:lpad(C_CHECK_NUMBER,6,’0’)"/>
Neither of the above works.
Thanks
Kishore

<xsl:variable xdofo:ctx="incontext" name="PADDED_CHECK_NUM" select="xdoxslt:lpad(C_CHECK_NUMBER,10,’0’)"/> worked for me. I missed the '$' sign to retrieve the value.

How to use lpad function in external table definition?

i need to modify one column of .csv file using lpad and want to insert it in external table.
lpad(AMT,3,'0')
Please send the code

Hi,
Please read SQL and PL/SQL FAQ
Additionally when you put some code or output please enclose it between two lines starting with {noformat}{noformat}
i.e.:
{noformat}{noformat}
SELECT ...
{noformat}{noformat}
The information you posted are quite poor. You don't expect to have an answer with such few details.
Anyway external table are read only.

How to find out where I have used a certain Global/Local Variable

Hi Friends
I want to track how and where the shared variable's value has been
changed/Read when I try to debug the program. Anyone
here had the expenrience on how to find a certain shared variable in
the Block Diagrams/VIs. I will very appreciate you help.
Cheers!

Hi All
I have tried the ctr+F to find a certain shared variabl, but the result came out is looks all the shared varibales. How can I focus on 1 certain shared variable. I am using labview8.2.1.
And I have tried the Find shared variables VI from the link Ben showed me. It can not work properly. It showed an error when I try to search, which says: Error 1057 as attached. Could anyone tell me why. Thanks.

Why import isnt needed whn ref is used without storing to local variable

Hello, Guys
Consider this statement
System.getProperties().getProperty("propertyname");
for this statement import of java.util.Properties is not required, but we are using method of Properties
but it will required for this statements.
Properties props = System.getProperties();
props.getProperty("propertyname");
Whats the reason??
Regards,
Nachiket

import is just a shorthand anyway, actually you don't really have to import anything. Import doesn't, of itself, generate any kind of external referencing, it merely allows you to shorten, for example, java.util.List to List.
The compiler knows the class which System.getProperties() returns.

How to use Min function to get FileName into a Variable

I was wondering how to use MIN function in Evaluate variable in package to get the first file name from the list(Datastore)
With reference to Merging Flat Files into a single file Post number-4
Thanx

Hi Diwakar,
That List data store should be table, than only it will gives the min of the filename string,
If it is a file datastore, Min function does not works properly it will returns a first name in the file data store.
so please, use an interface to upload the List filedatastore into some other temp table. From that table you can use variable to get Min value of file name.
Thanks

Is there an easier way to create a local variable?

I want to create a local variable, but I don't wont to have to find the terminal first and then use the option create-local variable. Is there a way to make a copy of an existing local variable? If I use the CTRL-C and CTRL-V option another terminal is created too.

> Great! That was exactly what I wanted. It even works if more than one
> variable is selected.
This may not apply in your situation, but I feel obliged to make this
warning anytime I see this sort of posting. If you find yourself making
too many local variables, it is worth checking to see if you are doing
things the best way.
If you are using the locals for communication between parallel loops or
for UI -- writing to controls, then keep trucking. That is why they
were added. If you are using them as storage locations, like variables
in BASIC or C, or to avoid wires, then you should definitely read the
devzone article about race conditions and the usage of globals/locals.
If not, you will probably find yourself with some monument
al debugging
sessions later on.
If you have questions, fire away.

Can you sort the "local variable" pick list?

My program has a lot of local variables. If I right click on a variable and click on "select item", a loooong list of all my local variables appears. They appear to be in the order in which they were created in my program.
Is there any way to modify the display to where the local variables appear in alphabetical order?
Amateur programmer for over 10 years!

The best solution is to not use a lot of local variables . Here is a neat trick to use local variables without having to use local variables . If you are using a state machine (case structure inside a while loop), create a cluster constant on the block diagram inside a state or case called "Local Defs". Inside the cluster, put constants for every local variable you will use. Label the constants like you would a local variable. Put a shift register on the loop border. Wire the cluster to the shift register on the right side. Do not initialize the shift register on the left side. In any case frame, you can wire from the left shift register into an unbundle or bundle to read or write to the Local. You never have to call the Local Defs state, the cluster will be defined because of the wiring. If using controls at many places, make a local constant for each control and have a state where the control is written to the local. Then you can read the local to use the value at any time. See attached vi for an example.

Shall I use global or local variables for my program?

Hello,
1) I am using 2 while loops in parallele. One 50 ms timed and the other one 1000 ms. The 50 ms one gets data from a sensor. I want to display that data every 1000ms in the 1000 ms loop. I have used global variables to do that. Should I better use local variables?
2) This question deals with the VI I have attached
a) Shall I initialise the " Quitter programme " global variable in the main VI aswell ? Or is what I have done enough?
b)
I want the sequence to continue ( finishes the last sequence and goes back to the first one without any delay if possible ) until the user presses Quit. I am concerned about the " wait until " icon of the exterior main while loop ( set to be 250 ms at the moment ). This time, 250 ms, is the time it takes between the end of the last sequence and the beginning of the first sequence? Is that right? Once u start the first sequence, the while loop doesn’t do anything until the end of the last sequence ( my 3 sequences can take several minutes ) ?
Hope I am clear… lol
Don’t hesitate to ask any questions if not clear enough
thanks a lot,
David

Bonjour Marc. You will definitely have a race condition because you are writing to the global in a parallel loop. You could click the stop button in the quitter program, then before it is read in the main loop, the lower loop writes a false to it, and your click is lost. Why do you want a separate quitter program? You may have a good reason but it isn't clear here. I would not use globals or locals for this, just put your stop button on the main vi. You already have one, so why do you want another one in another vi? If you must do it this way, eliminate both lower loops. They are not necessary. The global default is set to false, so when you run the vi, it is false. The button mechanical action is set to latch when released, so after clicking it will turn true until the main vi reads it, then it will automatically turn false. So you don't need the lower loops to keep writing false to it. If you just eliminate both lower loops, it will work fine. The only purpose I could see for the quitter vi is to have one button cause several vi's to stop. Instead of doing it this way, put one stop button in your main vi, create a reference (right click - create - reference), and wire this reference into all subvi's that the main calls. The subvi's must be changed to accept the reference and use it. This would be a much better method to close all vi's with one button.
You could also get rid of the sequence structure (it hides code and makes it more difficult to read). Just put all your code side by side. The error in/out wire will ensure that the execution order will be fixed, just like in your first sequence with the open file and write file functions. Just wire the error out of the write vi to the second write vi, and then the error out of the second write vi to the close vi. No sequence structure needed, and all your code is viewable on one screen.

Data Acquisition - using local variables to write data to a file

Hello,
I am running a Data Acquisition vi (currently in LabVIEW 7.1 but soon to be updated to 8.2) that collects ~100 parameters of data from several sources contained in a while loop. The current configuration (which I did not write) uses very few subVIs and writes to ~100 local variables to store each parameter. It then reads all the local variables and builds an array of all the strings, converts then to a spreadsheet string, then uses the write characters to file function to append to a datafile. I am trying to clean things up and have came up with subVIs to collect the data from the following sources:
8 serial port sources collecting btwn 8 and 20 parameters each
~15 thermocouple readings
~10 analog inputs
~20 parameters read off an ARINC 429 bus.
I have come up with a subVI to read each of the sources and have placed the subVIs in the while loop. Each subVI outputs the data that it collects in array or cluster form. I was wondering how best to write each parameter to a CSV file at between 1 and 10 Hz. Should I write each subVI output to a LV and then read them off as was done before (the difference being that I have reduced the # of LVs to ~10 vs >100?
I should add that precise timing is not that important, so if all the subVIs are not collecting simultaneously (which I understand that they won't be), it does not really matter.
Thanks.

Hi jilla,
jilla wrote:
What I think that you are saying is to turn the outputs of the 4 subVIs into inputs of a 5th subVI that writes to the data file. Correct?
Yes. It may sound like a fine-point, but I beileve it's better to create a VI specifically for formatting data - in your example, 4 arrays IN, a single string OUT. Then write the string to file as a seperate operation. GUI-displayed data can go through a similar transformation, the four arrays wired to a subVI which builds output-structures specifically for display. It's a beginner's mistake to put lots of individual controls and indicators on the screen when groups of them are naturally related (in an object-oriented sense.) Use clusters to group related controls - this will keep the diagram much cleaner.
One more question: at what point (either # of data points or frequency of data collection) does it become necessary to use queues? Thanks.
Well, there's not really a clearly definable "point". I'd say if your update-rate climbs above 100Hz, or you witness poor program or system performance, then it's time. The scenario you've described is a fairly simple acquire/display&log loop - and simple is good. Then-again people can't see/react-to updates faster than about 10Hz - so it doesn't make sense to sacrifice performance - if performance becomes an issue.
Re: queues: Queues are sometimes used to buffer data that's "produced" in one place and "consumed" in another.
Here, if/when logging data, you're logging with every DAQ. I wouldn't recommend using a queue to transport data from a "DAQ loop" to a "Logging-loop" - those functions can be in the same loop. Should/could a queue be used to get data from a "DAQ loop" to update the GUI at a lower frequency? Sure, but a Notifier might be a better choice. Further, in the (simple?) program you've described, you might use a case structure (True/False) to only update FP indicators every "X" iterations - a simple solution that doesn't require Queues or Notifiers.
Cheers!

Possible to use local variables in Calculation Manager

Hi,
I'm using calculation manager in EPMA for the first time. Have not found any function for using "local variables", i.e. variables that can be used for fixing on the current members a user has selected in a form. Do someone know if it is possible to use that functionality in calculation manager? And in that case, how do I find it?
Thanks!
Regards
Mats

Hi,
I guess you are referring to local variables in Essbase Administration Console. When you are in calculation manager (System View), you can go to Tools->Variables. There you can create variables at application, database (global) or business rule level (local variable). You can use these in Business rules by placing the name in curly bracket {...}.
The usage of the variables in the forms is the same as before.
If however, what you meant to say by local variables is substitution variables, yes you can use them in Calc manager the same way you use in calc script.
Cheers,
Alp

How to solve error using local variables?

I've created a sequence with a local variable.
But when I execute it, an error occurs since the first step (before the step where I manipulate the local variable).
The error code is something like:
Error in Evaluation. Syntax expression. Column [0-0]
It's interesting because it seems that once I've executed my sequence for the first time I can't create any other sequence where this error doesn't appear.

Pparo,
The problem does not occur under TS 1.0.3 on my system. However, I think we can get to the bottom of this.
When at a breakpoint in your sequence, if I type the expression "Locals.nls == 15-" in the TestStand watch window, I will get the message
Evaluation Failed: Syntax error in expression (Column 18-18)
I believe that this is the same type of error that you have encountered. Correct me if I am wrong.
The numbers after the word "Column" indicate where the error has occurred in the expression. In your case the error occurs at the beginning of an expression. The question still remains as to in which expression is error occurring.
Are you seeing this error reported in the watch window? If so, then you have typed the expression in the watch window.
If I copy the bad expression above into a the expression of a Statement step I get a run-time error of
An error occurred in the 'Statement' step of the 'MainSequence' sequence in 'Sequence File1'.
The post-expression for the step 'Statement' could not be evaluated.
Syntax error in expression.
Error Code: -17322
From what you report, the error appears to be located in your watch expression. When I executed your sequence with a breakpoint on the first step, I added the watch expression by selected the Context tab, expanding the Sequence Context tree view until I could see the nls variable, and then I dragged nls from the tree view to the watch window. This created the watch expression of Locals.nls. I also created the same watch expression by right clicking in the watch window, selecting Add Watch from the context menu, and selecting (or typing) Locals.nls. The expressions all evaluated to 24 without error.
This process has NOTHING to do with creating local variables. You asked if you are creating variables properly. There are only 2 ways to create variables in TestStand 1.0.3, neither of which you have described. The most common method is to select the Locals tab after opening your sequence (not during execution), right click in the right pane and add the variable of your choice. It seems like you did this correctly based on the sequence file you sent. The other method of creating variables is to do so programmatically. However, this is beyond the scope of this answer.
You ask a question about "the best way to create three constants in LabVIEW and pass them to a LabVIEW VI that is a step?" This implies to me that you want to create the strings within a VI called by one sequence step, and then use them in another VI called by a different sequence step. I would recommend taking a look at the example AccessingPropertiesAndVariables.seq that ships with TestStand. The first 3 VIs write values back to step properties, but could just as easily write them back to local variables. The 4th VI writes a file reference back to a TS local variable. The 5th and 6th step get the file reference from the TS local variable. You want to do something similar to the 4th and 5th VI, however, you want to send 3 strings to local TS variables, and then get them in the following VI. This will require using "TestStand - Set Property Value (String).vi" and "TestStand - Get Property Value (String).vi" which can be found in the TestStand function palette in LabVIEW. After reviewing this example you can then ask additional question. I recommend posting the question on a different thread since it is unrelated to your original question about the syntax error.

How to use local variables declared in b/t the methods in other views

Hi
i need to use the value of the local variables declared in b/w the views in one other view,as i have manipulated the value based on some condition & want to use it in 1 more view for my req.,but that variable is not global one just for once i need to use it,and i can't again write the whole for its conditions,as its there in initialization view,which if coded again,can hit the functionality there,so is it possible to use the value of such local variables thereafter or not,if yes pls let me know,or i need to declare the global variable for this.

hi,
1.Declare an Attribute in Component controller.
2. Pass the value to this Attribute in View V1.
using :
wd_comp_controller->Att = 'Saurav'.
3. Now in view2 , you can access this Attribute using:
data lv type string.
lv = wd_comp_controller->Att .
Here Att is my attribute of type string declared in component controller.

Store Counter Number in BODS using Global/Local Variable

Hi All,
Anyone done before adding a counter integer field into a table based on key via BODS?
Example:
Table 1 (contains just 1 field) <-Input:
Key 1
Key 1
Key 2
Key 2
Key 2
Table 2(contains 2 fields with INT as the 2nd field) <-Output:
Key 1      1
Key 1      2
Key 2      1
Key 2      2
Key 2      3
I was wondering if populating the Local Variable or Global Variable might work but from my understanding, inside the Data Flow , it's not possible to increase the variable value ($count = $count + 1).

Hi Maurice,
Thats a good idea!!
I had currently implemented a solution where i use Variables and Customize Functions to solve the problem.
Will give a try and see if your solution produce the same result.

Dbx: Can't evaluate local variables in optimized functions

I turned on the optimization for the whole product. Now I found that I can not print the local variables declared in side the main funciton or inside the function locals.
eg.
int factorial (int n)
int factorial = 1;
while (n > 1)
factorial *= n--;
return factorial;
When I tried to print n or factorial, I would not able to do so...
Is there any way can I get the local variables printed?
Is there any compiler options to overcome this problem and printing the local variables...
I know this is an difficult question becuase the locals go to Register instead of memory. By reverting it back to memory, I may loose the efficiency I gained with this optimizations.

dbx: Can't evaluate local variables in optimized functions

Dbx typically cannot show auto variables in optimized code. The reason is that the variables typically do not have a stable location, or might be eliminated altogether. Similarly, source code lines don't have a stable relationship to object code. The debug data emitted by Sun compilers is not enough to keep track of these issues.
We plan to provide better debugging of optimized code in a future release.
Dbx can show the value returned from a function, which in your case might be enough.
