While loop and for loop condition terminal

Hello friends,
I am using labview 8.6. The condition terminal of the while loop and conditional for loop is behaving in just the opposite way.
When i wire a true to the condition terminal of my loop, the while loop continues to run when I click on run. when I wire a FALSE, it stops.
Is there any setting change that I have to make it to get it work properly.
Please suggest on this.
Thanks and regards,
Herok

Whatever you are seeing must be due to some corruption or folding error. It all works fine here.
To make sure there are no hidden objects, simply press the cleanup button which would reveal any extra stuff (which is obviously not there). Does it fix itself if you click the termination terminal an even number of times? What if you remove the bad loop and create a new one?
Could it be you have some problems with the graphics card and the icon of the conditional terminal does not update correctly?
Whay happens if you connect a control instead of a diagram constant?
What is different on the computers where it acts incorrectly (different CPU (brand, model), #of cores, etc.)

i have written this code,i need to use cursor and for loops to get more than one rows and update also.
if there are more than 1 rows in cs_strmap_t,then the procedure throws an error stating that it cannot take 2 rows.

Why use cursor and for loop?

Hi All
So in general why would we use a cursor and a for loop to do update in a stored procedure?
Why wouldnt we just use a single update statement ?
is there compelling reason for using a cursor and a for loop: I am reading some code from a co-worker that the business logic for the select (set need to be updated) is complex but the update logic is simple (just set a flag to (0 or 1 or 2 or 3 or 4).
But eventually the select come down to a key (row_id) so I re-write it using just a single sql statement.
The size of the main table is about 2.6 to 3million rows
Any thoughts on that??
The code below I just do a google for cursor for update example in case for something to play with

Adding my sixpence...
PL/SQL is not that different from a SQL perspective than any other SQL client language like Java or C# or C/C++. PL/SQL simply integrates the 2 languages a heck of a lot better and far more transparent than the others. But make no mistake in that PL/SQL is also a "client" language from a SQL perspective. The (internal) calls PL/SQL make to the SQL engine, are the same (driver) calls made to the SQL engine when using Java and C and the others.
So why a cursor and loops in PL/SQL? For the same reason you have cursors and loops in all these other SQL client languages. There are the occasion that you need to pull data from the SQL engine into the local language to perform some very funky and complex processing that is not possible using the SQL language.
The danger is using client cursor loop processing as the norm - always pulling rows into the client language and crunching it there. This is not very performant. And pretty much impossible to scale. Developers in this case views the SQL language as a mere I/O interface for reading and writing rows. As they would use the standard file I/O read() and write() interface calls.
Nothing could be further from the truth. SQL is a very advance and sophisticated data processing language. And it will always be faster than having to pull rows to a client language and process them there. However, SQL is not Turing complete. It is not the procedural type language that most other languages we use, are. For that reason there are things that we cannot do in SQL. And that should be the only reason for using the client language, like PL/SQL or the others, to perform row crunching using a client cursor loop.

Removing Items While Using New For Loop

Consider this:
ArrayList<String> a = new ArrayList<String>();
... add some stuff ...
for(String s : a) {
// Do some stuff
if(some_condition) {
a.remove(s);
This will cause a ConcurentModificationException the a.remove(s) is ever run. Is there anyway to call the iterator.remove() method instead? The new syntax is much cleaner, and I'd like to use it, but I need to be able to call iterator.remove()
Anyone?

I think the code should iterate through a, putting
references to objects in an auxillary array and then
the loop will go through the auxilary array rather
than the original data structure. This perfectly
reasonable, but different implementation results in
drastically different results (the example above would
work fine). I see this as an issue of these general
language features being defined to close to the metal.
Their semantics are defined by their implementation
not by a sound language design decision that is
agnostic to different implementations.The enhanced for loop is defined in terms of java.lang.Iterable, a very simple interface, which can be implemented in many different ways. You can't get much farther from the metal. The concurrent modification exception is a feature of particular implementations of that interface. If you don't like those implementations, use others that behave differently. For example, you could use one of the CopyOnWrite collections implementations in java.util.concurrent, which never throw a concurrent modification exception. Your suggestion to copy the elements into an array is one (inefficient) implementation mechanism for such collections.

Apple Loops and the Loop Browser

maybe I'm missing something here, but whenever I save an edited audio file (or loop) with Apple Loops I can never seem to find the same file in the Loop Browser.
(unless that is how the app is suppose to behave ...)
I assumed the Loop Browser behaves somewhat like Logic's Project Manager, referencing and finding files that are associated with Logic Sessions.
Long story shot, how can i save my edited Apple Loop files and still find them using the Loop Browser
Thanks.

The additional content is not just the loops. It is also all the samples for the instruments etc.
You are correct, however, in the method of moving the loops.

Soundtrack Pro preview loops and non-loops are cut-off

I need help with this issue.
When I am going through the loop library/libraries, I click in a loop and it used to preview without an error, I am not sure when this happen, but now if I click in any audio clip from the loops and mixes libraries (about 7500+) clips, .aif and .caf audio files, in the library, all I get is half a second if not any preview.
When I open the clip, and press play, it seems to be choppy as well. it plays through but skips or pauses for a fraction of a second, but enough to know that it is not playing flawlessly.
I am not sure if this happen after installing the last Pro update or the 10.5.4 update.
I also have FCP and Motion, those applications seem to not have any issues.
Is there a way to reset the whole STP?
I am not sure all locations where the preferences are, I tried deleting all the libraries, and adding them later, that didn't work. I deleted the one preferences in my user preference folder, but that didn't do anything either.
Any help would be appreciated.
Thank you.

You may need to rebuild the loops index.
Open up Logic and display the Loops Browser
Open up FInder and locate the folder containing the loops as you describe
Drag the loops folders onto the Loops Browser
That will rebuild the index and all should be well.

Producer consummer loop and timing loop

Hi,
I have to acquire 32 signals and record each signals. I would like to acquire my signals at a sample rate of 100kHz. But I tried with a different sample read and I have always an error of overwritten.
In my producer loop I read and display all signals and in my consumer loop I record and resample my signal.
But I thought It was maybe I haven t a timing loop in my producer and consumer loop and it slow my read in the buffer.
So do you think my error due to I haven t timing loop? And if it s yes, where do I put my timing ? in the consumer or in the producer loop.
Thank you very much for your response

Why won't my audio loops and MIDI loops sync together in a project?

I have a number of guitar riffs in a project that I've been making into loops, as I wish to use these as ideas which I arrange in a new project. I've been saving the edited regions of the riffs by going to Region>Add To Apple Loops Library> and saving it as a loop, which is supposed to conform to tempo as stated. These are a blue icon with a little soundwave icon in it.
I have been doing the same with drum loops that I have created using the piano roll. These have a green icon with a note inside it.
I want to use these to create arrangements in a new file. Obviously I need them both to conform to various tempos together.
Why are my guitar riff loops comforming to my global tempo track, but as soon as I add a drum loop and change the tempo, the drum loop will conform but not the guitar.
I've also tried exporting each of the guitar riff (regions) as audio files because I read something in the manual about the audio files needing to be saved in as SDII to conform to tempo, but that doesn't work either.
What's the deal?

I'm no guru, I'm a neophyte, but I'm interested in the problem anyway.
"I have a number of guitar riffs in a project that I've been making into loops... I've been saving the edited regions of the riffs by going to Region>Add..."
I assume all of these regions are audio regions. Do they all have an anchor assigned to whatever you consider the downbeat?
"I've also tried exporting each of the guitar riff (regions) as audio files..."
Once imported anew, again, is there an anchor indicated. I think that may be key.
You say that sometimes they work? What have you changed when they do? The tempo?

Help with if statement in cursor and for loop to get output

I have the following cursor and and want to use if else statement to get the output. The cursor is working fine. What i need help with is how to use and if else statement to only get the folderrsn that have not been updated in the last 30 days. If you look at the talbe below my select statement is showing folderrs 291631 was updated only 4 days ago and folderrsn 322160 was also updated 4 days ago.
I do not want these two to appear in my result set. So i need to use if else so that my result only shows all folderrsn that havenot been updated in the last 30 days.
Here is my cursor:
/*Cursor for Email procedure. It is working Shows userid and the string
You need to update these folders*/
DECLARE
a_user varchar2(200) := null;
v_assigneduser varchar2(20);
v_folderrsn varchar2(200);
v_emailaddress varchar2(60);
v_subject varchar2(200);
Cursor c IS
SELECT assigneduser, vu.emailaddress, f.folderrsn, trunc(f.indate) AS "IN DATE",
MAX (trunc(fpa.attemptdate)) AS "LAST UPDATE",
trunc(sysdate) - MAX (trunc(fpa.attemptdate)) AS "DAYS PAST"
--MAX (TRUNC (fpa.attemptdate)) - TRUNC (f.indate) AS "NUMBER OF DAYS"
FROM folder f, folderprocess fp, validuser vu, folderprocessattempt fpa
WHERE f.foldertype = 'HJ'
AND f.statuscode NOT IN (20, 40)
AND f.folderrsn = fp.folderrsn
AND fp.processrsn = fpa.processrsn
AND vu.userid = fp.assigneduser
AND vu.statuscode = 1
GROUP BY assigneduser, vu.emailaddress, f.folderrsn, f.indate
ORDER BY fp.assigneduser;
BEGIN
FOR c1 IN c LOOP
IF (c1.assigneduser = v_assigneduser) THEN
dbms_output.put_line(' ' || c1.folderrsn);
else
dbms_output.put(c1.assigneduser ||': ' || 'Overdue Folders:You need to update these folders: Folderrsn: '||c1.folderrsn);
END IF;
a_user := c1.assigneduser;
v_assigneduser := c1.assigneduser;
v_folderrsn := c1.folderrsn;
v_emailaddress := c1.emailaddress;
v_subject := 'Subject: Project for';
END LOOP;
END;
The reason I have included the folowing table is that I want you to see the output from the select statement. that way you can help me do the if statement in the above cursor so that the result will look like this:
emailaddress
Subject: 'Project for ' || V_email || 'not updated in the last 30 days'
v_folderrsn
v_folderrsn
etc

Incorporating either of these into your query should assist you in returning the desired results.

Using Cursor and FOR LOOP to INSERT the data into table

Hi all,
I have SELECT statement that returns 3 rows:
PROCESSNAME
PROTDATE
IMM
2013-12-18
Metrology
2013-11-18
CT
2013-12-04
SELECT processName, MAX(NVL(protStartDate, protCreateDate)) AS protDate
    FROM TABLE(SEM_MATCH("{
            ?ipc rdf:type s:Protocol .
            ?ipc s:protocolNumber ?protNum .
            ?ipc s:protocolCreateDate ?protCreateDate .
            OPTIONAL {?ipc s:protocolSchedStartDate ?protStartDate }
            ?ipra rdf:type s:ProcessAggregate .
            ?ipra s:hasProtocol ?iprot .
            ?iprot s:protocolNumber ?protNum .
            ?ipra s:processAggregateProcess ?processName.
    }",sem_models("PROTS", "LINEARS"),NULL, SEM_ALIASES(SEM_ALIAS("","http://VISION/Data/SEMANTIC#"),SEM_ALIAS("s","http://VISION/DataSource/SEMANTIC#")),NULL))
        Group by processName
Now I need to INSERT these values into the table along with the other values.
these other values come from different table.
       INSERT INTO MODEL_CLASS_COUNTS (MODEL_NAME, CLASS_NAME, INS_COUNT, COUNT_DATETIME, PROCESS_NAME, PROT_DATE)
       VALUES
       ("$MODEL",
            "${i}",
        (SELECT COUNT (DISTINCT S) FROM TABLE(SEM_MATCH(
                        "{?s rdf:type :${i} . }",SEM_Models("$MODEL"),NULL, SEM_ALIASES(SEM_ALIAS("","http://VISION/DataSource/SEMANTIC#")),NULL))),
         SYSTIMESTAMP, %%here need to insert PROCESSNAME, PROTDATE%%
t was giving me error:
PL/SQL: ORA-22905: cannot access rows from a non-nested table item
so i enclosed sparql query into single quotes.
The code is as follows:
declare
type c_type is REF CURSOR;
cur c_type;
v_process varchar2(200);
v_pdate varchar2(200);
begin
open cur for
       ' SELECT processName, MAX(NVL(protStartDate, protCreateDate)) AS protDate   <-- it's complaining about this being too long identifier, i think...
        FROM TABLE
          (SEM_MATCH (
                        ?ipc rdf:type s:Protocol .
                        ?ipc s:protocolNumber ?protNum .
                        ?ipc s:protocolCreateDate ?protCreateDate .
                        OPTIONAL {?ipc s:protocolSchedStartDate ?protStartDate }

                        ?ipra s:hasProtocol ?iprot .
                        ?iprot s:protocolNumber ?protNum .
                        ?ipra s:processAggregateProcess ?processName.
                    }",SEM_Models("XCOMPASS", "XPROCESS"),NULL,
          SEM_ALIASES(SEM_ALIAS("","http://VISION/Data/SEMANTIC#"),
          SEM_ALIAS("s", "http://VISION/DataSource/SEMANTIC#")),NULL))
           Group by processName';
loop
fetch cur into v_process, v_pdate;
exit when cur%NOTFOUND;
--here I need to insert v_process , v_pdate into my table along with other values...
dbms_output.put_line('values for process and prod_date are: ' || v_process || v_pdate );
end loop;
close cur;
end;
exit;
Now, I get an error:
ORA-00972: identifier is too long
Does anyone know way around this?

Hi,
I tested something similar with insert into select and it worked fine :
insert into t_countries(ID,CITY ,POPULATION, DESCRIPTION, located, insdate )
SELECT 1 id, city, o , city||' is a nice city' description, max(nvl(locatedAt,'unknown')) as located,
SYSTIMESTAMP
FROM TABLE(SEM_MATCH(
    '{GRAPH :gCH {<http://www.semwebtech.org/mondial/10/countries/CH/> :hasCity ?cityID .
       ?cityID :name ?city .
       OPTIONAL{?cityID :locatedAt ?locatedAt .}
       ?cityID :population ?o .
    SEM_Models('VIRT_MODEL_MONDIAL'),
    SEM_Rulebases(null),
    SEM_ALIASES(SEM_ALIAS('','http://www.semwebtech.org/mondial/10/meta#'),
    SEM_ALIAS('prv','http://www.semwebtech.org/mondial/10/countries/CH/provinces/')
    null))
    group by city,o
    order by city;
Or with execute immediate :
declare
v_country varchar2(200) :='http://www.semwebtech.org/mondial/10/countries/F/';
v_text varchar2(2000);
begin
v_text := 'insert into t_countries(ID,CITY ,POPULATION, DESCRIPTION, located, insdate )
SELECT 1 id, city, o , city||'' is a nice city'' description, max(nvl(locatedAt,''unknown'')) as located,
SYSTIMESTAMP
FROM TABLE(SEM_MATCH(
    ''{<'||v_country||'> :hasCity ?cityID .
       ?cityID :name ?city .
       OPTIONAL{?cityID :locatedAt ?locatedAt .}
       ?cityID :population ?o .
    SEM_Models(''VIRT_MODEL_MONDIAL''),
    SEM_Rulebases(null),
    SEM_ALIASES(SEM_ALIAS('''',''http://www.semwebtech.org/mondial/10/meta#'') ),
    null))
    group by city,o
    order by city';
    dbms_output.put_line(v_text);
    delete from t_countries;
    execute immediate v_text ;
    commit;

Ref Cursor and For Loop

The query below will return values in the form of
bu     seq     eligible
22     2345     Y
22     2345     N
22     1288     N
22     1458     Y
22     1458     N
22     1234     Y
22     1333     N
What I am trying to accomplish is to loop through the records returned.
for each seq if there is a 'N' in the eligible column return no record for that seq
eg seq 2345 has 'Y' and 'N' thus no record should be returned.
seq 1234 has only a 'Y' then return the record
seq 1333 has 'N' so return no record.
How would I accomplish this with a ref Cursor and pass the values to the front end application.
Procedure InvalidNOs(io_CURSOR OUT T_CURSOR)

One remark why you should not use the assignment between ref cursor
variables.
(I remembered I saw already such thing in your code).
Technically you can do it but it does not make sense and it can confuse your results.
In the opposite to usual variables, when your assignment copies value
from one variable to another, cursor variables are pointers to the memory.
Because of this when you assign one cursor variable to another you just
duplicate memory pointers. You don't copy result sets. What you do for
one pointer is that you do for another and vice versa. They are the same.
I think the below example is self-explained:
SQL> /* usual variables */
SQL> declare
2   a number;
3   b number;
4 begin
5   a := 1;
6   b := a;
7   a := a + 1;
8   dbms_output.put_line('a = ' || a);
9   dbms_output.put_line('b = ' || b);
10 end;
11 /
a = 2
b = 1

How do i use Arrays and For Loops in Loading Multiple Images?

I am struggling to load a sequential array of images to appear like a moving image. So when u click the button the images load one after the other.
The code below is what i have so far, but it fails to do what i seek in that there's only one image loading which is the last image in the array, so either because the images are stacking up atop each other, or because i simply dont understand the basics...
And, i am unclear about what you said kglad, that my solution will be more complicated because i need to preload my image sequence and then use a loop to load it?
import flash.net.URLRequest;
import flash.display.Loader;
var count:int = 0;
var imageArray:Array=["1.jpg","2.jpg","3.jpg","4.jpg","5.jpg","6.jpg","7.jpg",
"8.jpg","9.jpg","10.jpg","11.jpg","12.jpg","13.jpg"];
for(var i:uint=0;i<imageArray.length;i++){
var btn:YourButton=new YourButton();
btn.ivar=i;
addChild(btn);
btn.x=0;
btn.y=0;
btn.addEventListener(MouseEvent.CLICK,clickF);
var ldr:Loader=new Loader();
addChild(ldr);
ldr.x=20;
ldr.y=20;
function clickF(e:MouseEvent){
    ldr.load(new URLRequest("D:/flash cs5.5/image_sequence/twirlSeq/"+imageArray[e.currentTarget.ivar]));
function loadComplete(e:Event){
     // first process loaded image, then...
    count++;
    if(count < imageArray.length){
        loadCurrentImage(); // load the next image
    } else {
        // sequencial loading complete, carry on to next activity
function loadCurrentImage(){
     ldr.load(imageArray[count]);
     ldr.contentLoaderInfo.addEventListener(Event.COMPLETE, loadComplete);

create a new fla, add btn and add the code i suggested. test.
var count:int;
var imageArray:Array=["1.jpg","2.jpg","3.jpg","4.jpg","5.jpg","6.jpg","7. jpg",
"8.jpg","9.jpg","10.jpg","11.jpg","12.jpg","13.jpg"];
var ldr0:Loader=new Loader();
ldr0.contentLoaderInfo.addEventListener(Event.COMPLETE,loadCompleteF);
var ldr1:Loader=new Loader();
ldr1.contentLoaderInfo.addEventListener(Event.COMPLETE,loadCompleteF);
btn.addEventListener(MouseEvent.CLICK,clickF);
function clickF(e:MouseEvent):void{
// initialize count
count=0;
// call loadF
loadF();
function loadF():void{
// add one of the loaders to the top of the displaylist and load the next image
addChild(this["ldr"+count%2])
this["ldr"+count%2].load(new URLRequest(imageArray[count]));
function loadCompleteF(e:Event):void{
// increment count
count++;
// check if the last has loaded
if(count<imageArray.length){
// if not clear the content out of the next loader.
if(this["ldr"+count%2].content){
this["ldr"+count%2].unloadAndStop();
// and call loadF so the next loader can load the next image in the array
loadF();
} else {
// if the last has loaded.
// last load completed

While loop in for loop

hello,
i have a problem with the following:
it starts and doesnt end. only the first "m" and "b" gets inside the while loop. afer "=" there is false. Why is this while loop standing still?

You could also make it without a while loop:
One thing to note about the above code. If the input arrays are not the same size the loop will only run a number of times equal to the length of the shortest array. If an empty array was input the loop would not run.

Difference between open loop and closed loop mode when finding the index on a stepper motor axis.

I have a test system which uses a PXI-7352 motion controller with a MID-7602 stepper motor drive to position a 200 step/revolution stepper motor with an attached 1000 line encoder. The MID-7602 is configured for 64 microsteps per step, giving 12,800 microsteps and 4000 encoder counts per revolution. The system is controlled using LabView 7.1 and NI-Motion 6.13. To home the motor, I've defined a sequence in MAX which first finds the reverse limit switch and then moves forward to the encoder index pulse.
When finding its reference in open loop mode, the system its reference at the same microstep each time. When findings its reference in closed loop mode, the system finds its reference somewhere within about a 20 microstep wide range.
I hope somebody out there with more experience with this controller can describe the difference between finding the encoder index in open loop mode and finding the encoder index in closed loop mode.
Thanks,
Mark Moss

Hello Mark,
I suspect that the behavior you are experiencing has today
with the resolution difference between your encoder and your
microstepping. Let me illustrate with an
example:
Example Setup
Stepper
Motor
NI
Motion Controller
10
steps per encoder pulse (Every 10 steps the controller gets an encoder
pulse, therefore positions 0-9 all appear to be 0 to the controller)
The
system has a maximum of 3 pull in moves set
Open Loop Scenario
The
system is commanded to go to position 9.
The
controller sends out 9 pulses.
The
motor moves to position 9.
Closed Loop Scenario
The
system is commanded to go to position 9.
The
controller sends out 9 pulses.
The
motor moves to position 9.
The
controller checks its position and sees that it is still at position 0
because it has not received an encoder pulse.
Because
the controller thinks it is still at position 0, it sends another 9 pulses
as its first pull in move.
The
motor moves to position 18.
The
controller checks its position and sees that it is at position 10 because
it has only received one encoder pulse.
Because
the controller thinks it is still at position 10, it sends1 reverse pulse
as its second pull in move.
The
motor moves to position 17.
The
controller checks its position and sees that it is at position 10 because
it has only received one encoder pulse.
Because
the controller thinks it is still at position 10, it sends and additional
single reverse pulse as its third pull in move.
The
motor moves to its final position of 16.
I believe something similar is happening with your
application as it looks for the index pulse.
Because the controller does not compensate for what it perceives as
position error in open loop mode, the motor always goes to the same commanded
position. In closed loop mode, the motor
is bouncing around inside the single index encoder pulse trying to find a
certain position.
There are several recommendations I can make towards
correcting this behavior. These
recommendations are in order of effectiveness:
Setup
your system so that there are more encoder counts per revolution than
steps per revolution.
Turn
off pull-in moves by setting them to 0 in MAX.
Use an
open loop configuration.
Play
around with the pull in window in MAX.
Regards,
Luke H
