For loop don't updates

Hi,
First I'm new at labview ,
I'm trying to read 8 checkboxs vals and for each checkbox I'm queuing a single val witch will be a test.
I have a problem with my for loop it simply won't update and staying at 0 val ( only one iteration )
vi is attached , can any one give me some help ?

I cant look at the code right now, dont have LV currently, but it sounds like you're either not looping at all, or not doing what you should inside the loop (but outside).
Could you post a .jpg/png? (usually we ask for the vi's instad )

FOR LOOP cursor that updates table A based on a value in table B

Hi,
I need a FOR LOOP cursor that scans and updates all pro-rata column in table EMPLOYEE(child) based on what pay classification all employees are on in the CLASSIFICATION(parent) table.
DECLARE
BEGIN
IF employee.emp_type = 'FT' THEN
UPDATE employee
SET employee.pro_rata = ((classification.yearly_pay/52)*52)
WHERE employee.empid = v_empid AND classification.class_id = employee.class_id;
END IF;
IF employee.emp_type = 'PT1' THEN
UPDATE employee
SET employee.pro_rata = ((classification.yearly_pay/39)*52)
WHERE employee.empid = v_empid AND classification.class_id = employee.class_id;
END IF;
IF employee.emp_type = 'PT2' THEN
UPDATE employee
SET employee.pro_rata = ((classification.yearly_pay/21)*52)
WHERE employee.empid = v_empid AND classification.class_id = employee.class_id;
END IF;
END;

Info records flagged for deletion don't update purchase orders

Hi, I would like to know how I can customize SAP-MM in order to avoid that the info records flagged for deletion update the purchase orders.
When I create a PO from a Purchase requisition (which have data with texts like "Vendor material number"), the Info record flagged for deletion update this data.
Thank you

Hello
I think inforecords flagged for deletion is not being considered for PO updation. Could you please check again.
It might be posible that 'Vendor material number' is spcified in Purchase requisition and when you create PO from Purchase requisition, it is copied from there to PO.
I hope it will resolve your issue.
Best regards
Avinash

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.

Parallelized for loop progress bar

I have a for that takes a long time to execute and enabled parallelism to speed things up. I also want a progress bar. Before enabling parallelism, I simple had an indicator wired to the iteration counter and the array size that is being processed. This gave a good percent complete indicator. With the for loop parallelized, the indicator bounces around depending on which instance of the for loop happens to update the indicator. Is there a way to have an indicator inside a parallelized for loop?

A better idea is probably a simple action engine that increments with each call, incrementing an integer in a feedback node, and returns the total count. Since it is not reentrant, it will be shared by all loop instances.
Here's a very quick draft. See if it works for you. (Warning, only use it in one FOR loop overall).
Probably needs a few tweaks....

Commit after every three UPDATEs in CURSOR FOR loop

DB Version: 11g
I know that experts in here despise the concept of COMMITing inside loop.
But most of the UPDATEs being fired by the code below are updating around 1 million records and it is breaking our UNDO tablespace.
begin
for rec in
      (select owner,table_name,column_name
      from dba_tab_cols where column_name like 'ABCD%' and owner = p_schema_name)
      loop
        begin
        execute immediate 'update '||rec.owner||'.'||rec.table_name||' set '||rec.column_name|| ' = '''||rec.owner||'';
        end;
      end loop;
end;We are not expecting ORA-01555 error as these are just batch updates.
I was thinking of implementing something like
FOR i IN 1..myarray.count
LOOP
                         DBMS_OUTPUT.PUT_LINE('event_key at' || i || ' is: ' || myarray(i));
                         INSERT INTO emp
                         empid,
                         event_id,
                         dept,
                         event_key
                         VALUES
                         v_empid,
                         3423,
                         p_dept,
                         myarray(i)
                         if(MOD(i, p_CommitFreq) = 0) --- When the loop counter becomes fully divisible by p_commit_frequency, it COMMITs
                         then
                                   commit;
                         end if;
END LOOP;(Found from an OTN thread)
But i don't know how to access the loop counter value in a CURSOR FOR loop.

To be fair, what is really despised is code that takes an operation that could have been performed in a single SQL statement and steps through it in the slowest possible way, committing pointlessly as it goes along (exactly like the example you found). Your original version doesn't do that - it looks more like some sort of one-off migration where you have to set every value of every column that matches some naming standard pattern to a constant. If that's the case, and if there are huge volumes involved and you can't simply add a bit more undo, then I don't see much wrong with committing after each update, especially if you track how far you've got so you can restart cleanly if it fails.
If you really want an incrementing counter in an unnamed cursor, apart from the explicit variable others have suggested, you could add rownum to the cursor (alias it to something that isn't an Oracle keyword), although it could complicate the ORDER BY that you might be considering for the restart logic. You could have that instead of the redundant 'owner' column in your example which is always the same as the constant p_schema_name.
Another approach would be to keep track of SQL%ROWCOUNT after each update by adding it to a variable, and commit when the total number of rows updated so far reaches, say, a million.
Could the generated statement use a WHERE clause, or does it really have to update every row in every table it finds?
Could there be more than one column to update per table? If so it might be worth generating one multi-column update statement per table, although it'll complicate things a bit.
btw you don't need the inner 'begin' and 'end' keywords, and whoever supplied the MOD example you found should know that three or four spaces usually make a good indent and you don't need brackets around IF conditions.

I am done with Verizon for their inability to update Android in a timely manner. When my contract is up, after 10 years, I am gone.

Verizon,
Nobody.. and I mean NOBODY is buying your crap. You don't update to the latest software in a timely manner. The entire planet has the KitKat update for Android and you don't under the guise of better experience. That is crap, everyone else can do it but you, you are inept.
Additionally, you are the most expensive by far and the guise of biggest network. I really don't care about the biggest network, I use a very small percentage of it so this is no excuse. AND if you are the biggest how come EVERY carrier can beat you on price and get updates out faster?
Your new tiered plans "Family Share" crap.
I do how you still charge me for data, voice, and text.. even though at the end of the day these are all just data packets across your network. I love being charged three times for the same service though.
You want to really be the best, then change your ways.. but I am done waiting around for you.. this contract ends and I am gone.

After 20 yes TWENTY YEARS being with Verizon I to am done with their cell phone business. I have had nothing but problems with my "new" Droid, which I was "steered" to by a tech who told me what I should have not what I chose, my weakness was to still trust the employee had the best interest of their customer at heart. Brewhahaha! Boy what a error that was on MY part. I got a phone that has been defective from the moment I turned it ON.
I first had home service with Verizon for many years...then wifi....then the bundle. Great, all I can say is as this company has grown, they have fallen apart on their customer service and their policies. Their nothing more than yet another CORPORATE mentality company whose bottom line is PROFIT.
My droid arrived, it would not hold a charge...it would not always take a preference I chose...it would change things on preferences on it's own (wondering if my phone is like that car in the movie "CHRISTINE") and was encouraged to keep using it, I just either didn't understand the "smart phone" ...or my age was allowing them to think I could no longer learn to use anything other than a rotary phone. One tech actually told me to take the battery out and reset the phone, hmmm...sure right and ruin the phone? RIGHT...who trains these people???
Verizon is no longer any resemblance of the once good company it just to be.
Today my day was horrible. (your just lucky I told blab on about the last three months dealing with them!)
Having just spent the majority of my day being transffered from one department to the next (seems they now have to transfer you if there is something as simple as adding an e mail to the order that was cancelled in error by the way to replace the lousy dysfunctional Droid I got) no one person can do what ever your account needs. Half way through my completely messed up day, I got so tired of this syrupy fake responses telling me to have a wonderful day and enjoy the rest of my day..and it was a pleasure to serve me.... after way to many transfers to other departments...they started sounding like they were recorded bots...or flight attendants. I just had to ask them if they served peanuts and cold drinks. HARD LIQUOR?
So now I am waiting for my "reburbished" droid. (again)..checked on why I had not gotten it...it was cancelled flagged by "fraud". WHATTT? Fourth time I have ordered something and this has happened, and no e mail asking me to contact them. I live in a senior gated community and they are trying to tell me "someone in your gated community attempted to commit fraud" so MY order gets flagged. (half the seniors in this gated community are half dead the others are either in Palm Springs or traveling...and the one who are slightly mobile...might not remember how to even get to the mail room .and back to their house..granted UPS requires I SIGN for the phone...but impossible since they flagged and did not send the phone out. So, here I sit, wondering after three months of dealing with these (not so funny) clowns and gain absolutely NO satisfaction, except to say....adios...when my contract ends. AT&T hopefully is better, but who knows..this phone situation may be the death of me yet..and in the end VERIZON will not longer have to waste their time or mine transferring me to try to get a 1. working phone 2. my order actually processed correctly 3. have to re-educate their techs.
I no longer TRUST Verizon, I no longer believe they have the interest of their customers at heart. (what heart?) and about the only thing I don't understand is they sell me a phone, then a package to buy time...but also $30.00 a month fee to connect to their lines? Shouldn't that rather come with the package deal??
Signed..done with Verizon squeezing me two ways to Sunday. I just hope some other company comes in with a plan to beat the socks off these top providers of cell services in the states...and I'd like to just sit back and watch the huge exodus of people leaving. The pickens are ripe to do just that.

TS4083 My folders that message rules divert emails to don't update when I open Mail on my iPad or iPhone. Only the inbox does. I have to click on each folder for it to update. Is there a way around this? The folders update on my mac fine when i check mail

My folders that my message rules on iCloud divert emails to don't update when I open Mail on my iPad or iPhone. Only the inbox does. I have to click on each folder individually for it to update. A real pain as I have about 30 folders. Is there a way around this ? The folders update on my mac fine when i check mail without having to select each one of them. Can the iPad and iPhone do the same thing?

My Mac has 4 mail accounts coming into it, but you are correct, one of them is a POP account, (and unfortunately it is the main @ account, and is the one associated with my apple id, since we've had it for years). I couldn't figure out how to replace this with the Imap version, short of deleting that account entirely.
Is this what I have to do?
Thanks for your help!

What 'redeem code' are you expecting, and why do you think that you need one ? iTunes gift cards are country-specific (they can only be redeemed/used in the country in which they were issued), if they aren't available in your country then you won't be able to get one. You shouldn't need a gift code in order to update an app.

Updating sceen elements in a for loop?

Hi
I have a for loop that, among other things, contains an appendText command. It adds a character to a text box on the screen.
I notice that rather than append the text on each iteration, it waits until the for loop has finished, and then appends all the characters.
It's not noticable on short loops, but very noticable on longer ones.
Is there a way to make flash update the text box as each iteration happens, rather than dump all the appended text at the end?
Thanks guys.
Shaun

Hi Kenneth
I've been playing around with that this afternoon, and am making progress, but was wondering if you could please explain it a little with regard to my code?
The function I want to have a graphical progress on is populateOutputBox(). Basically, it's taking data from an array (songlist), adding text to each array item, appending the result to a text box, and then the save function saves the data from the text box as a txt file.
It was working fine as a for loop, but as you've shown, no screen updates could happen if a lot of data is being processed.
So I've changed populateOutputBox to do one iteration, and on each check if the array has been iterated through.
Here's that code, followed by the code I've taken from your tut for checking on each frame:
function populateOutputBox() {
   //blah blah code for adding text to array items, then...
    p = p + 1;
    if (p == songlist.length)
            saveFunction();
    else
            populateOutputBox();
function startFunc() : void {
    addEventListener( Event.ENTER_FRAME, onCycle );
    //populateOutputBox();
function onCycle( event : Event ) : void {
   var cycle : Boolean = true;
   var startVar : Number = getTimer();
   var milliseconds = 1000 / stage.frameRate - 1;
   while( cycle && (getTimer() - startVar) < milliseconds ) {
       cycle = populateOutputBox();
   if( cycle == false ) {
       removeEventListener( Event.ENTER_FRAME, populateOutputBox );
As it stands, Flash seems to do nothing when I run it. Am I supposed to initiate populateOutputBox(); in the startFunc(), or does that happen automatically in the onCycle func?
Thanks again Kenneth.

How do you delete old music that it don't want anymore for the iOS 7 update. It gave me all the music I deleted in the past.

How do you delete old music that it don't want anymore for the iOS 7 update. It gave me all the music I deleted in the past. I tried going to settings and turning off music from the past and it got rid of my music I recently purchased.

Hello there, Syd_ma22.
The answer to how to delete a song on your phone in iOS7 is found on page 62 of the iPhone User's Manual:
http://manuals.info.apple.com/MANUALS/1000/MA1565/en_US/iphone_user_guide.pdf
Specifically:
Remove a song from iPhone. Tap Songs, swipe the song, then tap Delete. The song is deleted from iPhone, but not from your iTunes library on your Mac or PC, or from iCloud.
Thanks for reaching out to Apple Support Communities.
Cheers,

Real-time updates of an XY graph with a 2D array (x,y) inside a for-loop

Hi all,
I am new to this forum, and relatively new to LabView (I've used TestPoint in the past), and I have a question. I have implemented a for-loop to grab data from an LCR meter (via GPIB) which becomes the Y data. The X data is calculated and tunneled into the for loop (although varies with incrementing 'i'). Anyhow, I am trying to store all of the data and keep the user updated throughout the test by plotting the XY Graph each iteration. Right now, the XY Graph plots one point at a time, so somehow the data I am appending to the 2D array (x,y data) is getting overwritten each itteration. How can I make it so that each new point is added to the array, making it bigger so that the data will be saved and so that the user will be able to see all the data in real-time on the graph as the test in running?
Thanks
P.S. I would post a screenshot, but I'm not sure how to upload here.

Hey Mendeleev3104,
There is an attachment section at the bottom of the post when creating or editing a post. You might want to use that to attach a picture of your code.
None the less I will give a shot with some suggestions without viewing your code.
You should look into using shift registers along with the Insert Into Array.vi to build an array of numbers. A good source of information for shift registers can be found in the For Loop and While Loop Structures help.
Hopefully this helps!!

Thunderbird just done an update on my computer but now in e mails iv`e lost all my folders I had, For example I had a folder for my receits and other e mails I wanted to keep.

can you provide a bit more info before you do anything.
I'm presuming this is a pop mail account - please confirm.
First, make sure hidden files and folders are visible:
The AppData folder is folder is a hidden folder; to show hidden folders, open a Windows Explorer window and choose "Organize → Folder and Search Options → Folder Options → View (tab) → Show hidden files and folders".
* Help > Troubleshooting Information
* click on 'show folder' button
* click on 'Mail' folder.
* Please post image of the contents of the 'Mail' folder.
In thunderbird:
* right click on mail account name and select 'Settings'
* Select 'Server Settings' for the mail account
* Look bottom right for 'Local directory'.
* Put mouse cursor in the text box, then use keyboard arrow keys to navigate to the far right..some of the directory will be hidden as it does not fit it all in, so keep going to the right until you reach the end.
* Then left click, hold down and move mouse to the left to highlight the entire entry.
* Right click on highlighted area and select Copy.
* Paste info into this question in the forum.
