Case structure with arrays

why don't the array values are not shown in array 0 and array 1 in the enclosed attchment array0.vi.
thanks

Then default value then NOT wired is an empty array. So using array 0, as an example. It will be filled with data on iteration 0. But this data will be overwritten with an empty array. In the next iterations.
Besides which, my opinion is that Express VIs Carthage must be destroyed deleted

Case structure with more than 200 cases, slower lab view app

Problem Description :
i am currently making a vi which compose of a simple case structures, a case structure with more than 200 cases, what i noticed is that the more i added cases the slower the labview reacts, it takes time for me to route wire on each of the cases.
i dont know if there are any setting in the labview environment that i can increase the buffer size? i dont know... but its getting slow (only on the
vi with more cases in a case structure)

Can you clarify what you mean by "slow". Does it run more slowly or does it feel sluggish during editing?
Could you attach the actual VI?
Overall, I agree with the notion of local variable overuse. For example, you read the same local variable twice in the same case. Is there a need for this? Is there a chance that it varies between the two reads? Typically, you would place the terminal in front of the case structure and wire to all the locations where you need the value. This ensures that the data is consistent. Still, this should not cause any slowdown problem.
(On a sidenote, the code in the upper left corner is inefficient. You convert the same data to lower case with each iteration, so you might want to place this before the loop and do it only once (well, if you are lucky, LabVIEW will fold the operation, but still....). Also your "index array" operation can be replaced by autoidenxing of the 2D array on the outer loop boundary.)

Sort values of structure with arrays

Hi
For a shopping cart I'm using a structure with arrays to store the items in the cart. I tried to use StructSort but did not work...
This is how I store the items in the cart:
<cfscript>
            if (not(isdefined("session.cart"))) {                // Check to make sure that the Shopping cart structure exists.
                session.cart = structnew();
            // The item structure we are going to use to store the items in the cart
            // is going to have four parts...
            //         1. The item id
            //         2. The item name
            //         3. The price per unit
            //         4. The quantity
            tempvalue = listtoarray('#attributes.id#,#attributes.name#,#attributes.price#,#attributes.quantity#') ;
            // if the item is not yet in the cart, simply add it to the cart
            if (not(structKeyExists(session.cart, attributes.name))) {
                StructInsert(session.cart,attributes.name,tempvalue);
            // if the item is already in the cart, update the item quantity
            else {
                tempvalue[4]=session.cart[attributes.name][4]+attributes.quantity;
                StructUpdate(session.cart,attributes.name,tempvalue);
</cfscript>
Any help will be appreciated.
Thank you.

To loop over an array one has two options:
<cfloop index="i" from="1" to="#arrayLen(a)#">
Or:
<cfloop index="someVar" array="#a#">
Personally I use the former because I think the implementation of array-looping with <cfloop> is cocked-up as it's not the index that gets put into "someVar", it's the array element itself. So by way of pedantic protest, I don't use that syntax.
But anyway...
The reason why your struct is unordered is because structs are - innately, and by definition - unordered. If you want an ordered data structure, you use an array.
However what you are wanting to do is to sort your array by a subkey value of the structs the array contains. If you want to do that, you will need to roll your own sorting solution.
Personally I'd stick with using an array and just use its intrinsic ordering (the order in which items are added to it). However if you wanted to sort on one of the inner struct keys, you could maintain a separate struct keyed on the value you wish to sort on, containing a reference to the array element in the original array. Then you could extract a structKeyArray() from that, and use arraySort() to order those index keys in whichever order you like.

CASE STRUCTURES WITH TAB CONTROL

Hi,
I have created tab controlled case structures for three different cases,
Tablet type
Machine Input
Output
It seems that data is not interlinked while switching betweeen the cases.
I have to select the start buttun for each tab to get results.And also if I skip the second tab and jump to third tab, it doesnot give results. SOmehow the data is not acquired.
Can anyone help me out for the same.
Attached is the main VI (PAR_LAB_ATT_00_01)followed by a sub VI(gen time array)

Please don't use all CAPS when posting your message subject.
How are you running your VI? I don't see any while loop in it, so it only runs once. Which means only the case structure associated with the tab that is currently highlighted before you press the run button will actually run.
The vast majority of the time, a tab control is only used to control what is displayed in the front panel and is not used to actually control the execution order of the program.

Converting from case structure to arrays

I am working on a set up that write out 8 digit binary to a connector block. I had it set up with a case structure but there are over 40 different writes and it is becoming way too convoluted. I know it would be much easier to do this with arrays but I have no idea how to use them, please help.

Here is a quick attempt to do everything with arrays. See if it makes sense to you. As you can see, the code is much simpler. (LabVIEW 8.0).
You should be able to adapt some of the ideas. Many additional simplifications are possible, for example you could calculate the port 0 values directly from the outputs of the upper Q&R function. Try it!

How do I use a Case Structure with Strings?

I need to use a string list to set up a set of cases to be performed. Is it possible to tell a single case structure to do "a, b, c, and d, but not e or f" or "do a, c, d, and f, but not b or e" etc... when you use a string containing the cases to be used?

Blackavar,
A case structure will only execute a single case at a time. If you want to have multiple cases execute in parallel, then you would need to have multiple copies of the case structure and split the string apart and wire them to all of the needed case structures.
This could be done with reentrant subVIs to run truely in parallel. Anther method would be to have 6 different case structures, all with 7 cases each. The 7 cases would be "a", "b", "c", "d", "e", "f", and "0". Your input sting will need to be built up so that it will always be 6 characters long and then split up so that each character goes to one of the case structures. You would have your needed code for cases a - f. Case "0" would do nothing.

Building a case structure with four boolean (true/false) inputs.

I currently have two boolean inputs that I would like to use to select cases in a case structure. I would like to have four cases, each one dependent on the true/false condtions of the two booleans. If boolean 1 =true, then case 1 should be used, if boolean 2=true, then case 2 should be used, etc.
What structure should I use to convert these boolean inputs into numeric cases?

Or build them in to an array and "Search 1d Array". If you are only looking for a single bool being true, this would be easier because your cases could be {0,1,2,3} instead of {1,2,4,8}

Execute Case Structure with Button Press Slows Down VI

Hi -
I'm fairly new to LabView, and I am having some issues with using a button to run a timed while loop.
I am writing a VI that outputs a timed voltage pulse to an output channel on a DAQ; meanwhile, the VI reads and graphs the voltage on three input channels on the DAQ. When I use a timed loop that automatically executes when the VI runs, the program works. However, I would like to include a button so I can control the timing and number of voltage pulses sent to the output channel, instead of sending only one voltage pulse each time the VI runs. I have tried to do this using a button wired to a case structure. If the button is 'true,' the VI should send the voltage pulse. If the button is 'false,' the VI should keep the voltage at zero.
When the button is 'false,' the VI runs normally; however, when the button changes to 'true,' the VI slows down and never sends the pulse. Why does this happen? How can I fix it?
Also, how can I send the voltage pulse only when the value of the button changes? I only want the timed loop to execute once when the button changes value.
Thanks for any help or advice!!!

The graph is in the same while loop as the case structure. The while loop won't iterate until all the code inside of it has completed. So the graph only gets updated once, and won't update again until the while loop iterates again. If you need more continual updating you may want to put that in a loop that executes a couple of times, or completely separate your code into 2 while loops. Is it that long of a wait considering your pulse length is 1 second?
Your analog output code is just writing a voltage out (7 volts) until it eventually writes out 0 volts. There is no reason for it to drop down unless you have some sort of electrical problem between your DAQ device and the device on the other end that is reading the 7 volts. What are you connecting that analog output too?
What if you don't use LabVIEW and try to test out that analog output using Measurement and Automation Explorer? Does it do the same thing?

How about an Error Case structure with warning?

Hi,
while wiring some vis and thinking about error handling....
In most cases the simple case structure feet by the error cluster will do the job. However in some cases when you deal with warnings, wouldn't it be nice to have an additional (optional) warning case that is true for a not empty source string and/or an error number?

I forget to mention: Of course there is a solution possible by unbundling the cluster and check the error number and string followed by a case. I still remember the time when the case selector couldn't handle the error cluster ... (started with LV3.1 )
I just thought it would be a nice thing when you wire the error cluster to the selector and get the red and green case and you can right click, add a case and get a yellow(?) case named 'warning'

I now understand what you were saying about inlining a subvi. I did as you said and made a subvi with a case structure and an indicator within it. I use the New VI Object node to add that subvi to the slow-inlining parent VI. Then I tried to inline it using the invoke node, but I got error 1399, which make sense. Is this what you meant for me to do, or did I misunderstand?
Also, I tried the ControlTerminal reference approach you mentioned earlier. Unfortunately when I called the move method on the control terminal property and had the 0th frame of the case structure as the owner I got error 1060 again.
I really appreciate your help. Do you have any other thoughts?

Case structure with two selectors

Hi all
Once again I'm wondering...
...if it is possible to wire more than one value to a case structure. I'm just working on a project and came to a point where I have to nest case structures. I have two enums and depending on both enums I set a value.
How would it be to have more selectors so that the following code extract could be "drawn" with just one case structure?
enum X1 = {manual, auto}
enum X2 = {red, green}
if(X1 == manual && X2 == red)
else if(X1 == auto && X2 == red)
Maybe something useful for new LV versions, if it does not exist yet.

@David - Great solution. I might remember it one day .
@Shane - You could have given me at least "en stutz" . Well, I see your point, but in every textual language exists this possibility. Although your argument is acceptable (the compound enum), I prefer to have enums without combinations. Ok, maybe the values would make some sense, but I like it better if they are separate. In addition, what should I do if one input is an enum and the other a boolean? And now don't say "use DavidCrawford's solution" .

Using Event Structures with Array of Clusters

Using LabVIEW 8.5
Hi all,
I'm trying to convert an existing application to one that can be used
through a touch screen. I updated the UI and added an event structure
to listen for mouse ups on controls that require a HMI keyboard or
numpad to show up. Although I've been programming for a while, I'm new
to LabVIEW and am struggling with a problem:
Is there any way to have an event case listen to an event within
arrays? I've seen a few examples on the forums, but they all start with
breaking up the arrays into individual variables. Using the variables,
they build arrays. This seems pretty tedious, and I'm pretty sure I
can't apply it to one of my arrays. Essentially, I just want to know
which cluster in which array the user has clicked on, so I can open the
HMI keyboard or numpad and send the text to that cluster. In my watered down app (Array of Clusters.vi), I've put 3 arrays of clusters and a few stand-alone controls to give you guys an idea of what I'm taking about.
BTW, I'm using the HMI Keyboard and Numpad built by the Beta Community (http://decibel.ni.com/content/docs/DOC-1062) and modified it to add a "Clear" button to the keyboard and numpad. Please let me know if I implemented this in the best way.
Thanks for the help,

You probably can adapt some of it for the arrays on the right. If the array can be scrolled, you also need to account for the "indexvals" offset.
The Layers controls is easiest, because you only show one element. Just read the "index vals" property to get the array element and parse the coordinates to get the cluster element.
btw: the small while loop on the right serves no purpose at all and acts just as a CPU burner. You can delete it without any change in functionality. Is there anything else to it?

How to share structure with arrays in a single file between C# and C with arrays?

It is possible to define things so that a file that contains a struct definition can be included in both C# and C programs once the differences are taken into account. Most of these differences can be handled but not all. One of those problems is arrays.
Here's a contrived example of a file that can be imported directly into either a C or a C# project. If '__c__' is defined then the file is being imported into a C++ project. If not then the file is being consumed by a C# project. This simple little
thing allows those things that are different between the two environments to be taken into consideration. The one really knotty problem is how to handle arrays. In C, an array can be given a fixed size in a struct. Not so in C#. C# generates a compile time
error. I've been working around it so far by numbering the elements in the C# branch.
// If '__c__' is defined then the file is being included in a C project.
// If not then the file is being included in a C# project.
#if !__c__
// C# can utilize a namespace. C cannot.
namespace CrossPlatform
// C# wants to include the struct in a class.
public class Structs
#endif
#if __c__
// C defines a struct as a named typedef.
typedef struct _RtInfo
#else
// C# wants a struct object with a name.
public struct RtInfo
#endif
// Simple value types and previously defined structures
// can be shared directly between both C and C#.
float f;
#if __c__
// Arrays cannot be shared. C can use arrays with a size.
int v[4];
#else
// but C# cannot deal with sized arrays at all.
int v0;
int v1;
int v2;
int v3;
#endif
#if __c__
// C optionally gives the struct a name.
} CALDATA;
#else
// C# does not do that here.
#endif
#if !__c__
} // end of class.
} // end of namespace block wrapper.

What are right parameter types of ODCIIndexInsert in case of creating indextype WITH ARRAY DML option (documentation mismatch)

Hello.
During developing Domain Index for Oracle 11.2.0.1.0 (problem also appears in 12с) i was faced with misunderstanding of parameter types of function
ODCIIndexInsert in case of creating indextype WITH ARRAY DML option
According to Oracle documentation
http://docs.oracle.com/cd/E11882_01/appdev.112/e10765/ext_idx_ref.htm#i76892
In case of WITH ARRAY DML option Oracle will invoke ODCIIndexInsert with following signature
FUNCTION ODCIIndexInsert(
ia ODCIIndexInfo,
ridlist ODCIRidList,
newvallist varray_of_column_type,
env ODCIEnv)
RETURN NUMBER
In my case indexed column has datatype NUMBER so i defined varray_of_column_type as SYS.ODCINumberList
STATIC FUNCTION ODCIIndexInsert(ia in sys.ODCIIndexInfo, ridlist in sys.ODCIRidList, newvallist in sys.ODCINumberList, env in SYS.ODCIEnv) RETURN NUMBER
Indextype was created as
CREATE INDEXTYPE test_index_type
FOR
test_eq(number, number)
USING index_methods
WITH ARRAY DML(number, sys.ODCINumberList)
WITH LOCAL RANGE PARTITION
WITH SYSTEM MANAGED STORAGE TABLES;
or
CREATE INDEXTYPE test_index_type
FOR
test_eq(number, number)
USING index_methods
WITH ARRAY DML
WITH LOCAL RANGE PARTITION
WITH SYSTEM MANAGED STORAGE TABLES;
(problem occurs in all cases)
CREATE TABLE test_table (id NUMBER (19,0));
CREATE INDEX test_index ON test_table(id) INDEXTYPE IS test_index_type;
When attempting to insert data in the table
insert into test_table values (1);
oracle raise exception
Error starting at line 53 in command:
insert into test_table values (1)
Error at Command Line:53 Column:1
Error report:
SQL Error: ORA-29925: cannot execute SCOTT.INDEX_METHODS.ODCIINDEXINSERT
ORA-06553: PLS-306: wrong number or types of arguments in call to 'ODCIINDEXINSERT'
ORA-06553: PLS-306: wrong number or types of arguments in call to 'ODCIINDEXINSERT'
29925. 00000 - "cannot execute %s"
*Cause:    The specified function does not exist or does not have an
           appropriate signature.
*Action:   Implement the function with the appropriate signature.
So my question is.
Is it normal behavior of oracle (according to documentation)?
What is correct signature of ODCIIndexInsert function in case of INDEXTYPE creation with 'WITH ARRAY DML' option and fact that indexed column has NUMBER datatype?
By the way if i define indextype without 'WITH ARRAY DML' option signature is clear, and working. But this approach doesn't satisfies our performance needs.
Also if i define index type with option 'WITH ARRAY DML WITHOUT COLUMN DATA' and use signature
static function ODCIIndexInsert(ia sys.odciindexinfo,   ridlist sys.odciridlist, env sys.ODCIEnv) return number
Everything works too. But this approach doesn't satisfies our business needs.
Is it a way to define ODCIIndexInsert parameter types (in case of indexing number column) so that batch inserting works according to documentation ?

      ia ODCIIndexInfo,
      ridlist ODCIRidList,

Is there a known issue with emailing from case structures

Hi,
I am working on a quality control vi for data coming in as a text string. I need to be able to have the vi perform a check with the responce to the check (true or false) will cause different steps to then be performed. I was able to get the vi to perform 1 check and email out if the responce was false. When I tried to add a second check if the responce was true, the vi would run without any errors but would not email out or would only email out from the first check even if the first check passed and it was the second check that failed. This was all done without case structures. I then started using case structures with the true responce leading to other checks but the false responce leading to an email generation. For some reason even a simple one check with the email generation happening in the false case will not work. There are no errors or anything, it goes through the whole process correctly but will not send an email. Please help!!

Hi,
Here is the vi and the sample text file it calls for. You will of course have to change the path name. Feel free to call me if you have any other questions. Thanks
