For Loop - How to retain data generated inside even if prematurel​y terminatio​n by user?

I have a loop that executes x times and each time generates a unique data point. If I wanted to give the user the ability to stop the loop before it finishes, an eventually save the data, how can I keep a hold of the data that has been generated up to that point? If I put an array outside of a loop the data doesn't get filled in until after the loop is complete, and an array inside of the loop only retains one data point for some reason.
Please keep in mind that I am relatively new to LabView so would appreciate fully explained answers.

However the auto-indexing doesn't seem to actually output the data for use until all the loop iterations are complete. In my case though I may need to do stuff with the data that has already been generated before it completes.
How do you figure that?  The auto-indexing tunnel will return values for all the iterations that have been completed.  Post your VI if you are still having problems.

    Hi fais,
    Following through with what JB suggested. The steps involved in replacing the inner for loop with a while loop are outlined below.
    You can replace the inner for loop with a while by doing the following.
    1) Right-click of the for loop and select "Repalce" then navigate to the "while loop".
    2) Make sure the tunnels you where indexing on with the for loop are still indexing.
    3) Drop an "array size" node on your diagram. Wire the array that determines the number of iterations your for loop executes into this "array size".
    4) Wire the output of the array size into the new while loop.
    5) Set the condition terminal to "stop if true".
    6)Drop an "OR" gate inside the while loop and wire its output to the while loops condition terminal.
    7) C
    reate a local of the boolean "stop" button, and wire it into one of the inputs of your OR gate. This will allow you to stop the inner loop.
    8) Drop a "less than" node inside the inner while loop.
    9) Wire your iteration count into the bottom input of the "less than".
    10) Wire the count (see step 4 above) into the top input of the less than. This will stop the inner loop when ever the inner loop has processed the last element of your array.
    Provided I have not mixed up my tops and bottoms this should accomplish the replacement.
    I will let others explain how to takle this task using the "case solution".

  • How to retrieve data from inside the folders in SharePoint SSRS

    Hi ,
    How to get the data from inside the folders and subfolders.
    How can I do that.

    Hi Vinodaggarwal87,
    According to your description, you want to retrieve data from sharepoint list in a sub folder. Right?
    In this scenario, we should select the XML data source type and in the connection string provide the
    List.asmx service URL when creating data source. Then we need to use the List web Service and specify "recursive" for ViewAttribute in Lists.asmx. For detail steps, please refer to the links below:
    Generate SSRS report on SharePoint List with folders using List Service.
    SSRS: how to specify ViewAttributes when creating a report against a SharePoint's list
    If you want to set the ViewAttribute on CAML query level. You need add the view tag outside of query tag:
    <View Scope="RecursiveAll">
        <Query>
            <Where>...</Where>
        </Query>
    </View>
    Reference:

  • I'm creating an array using a for loop, how do I get the values outside the loop while it is running? thanks

    I'm creating a set of values using a for loop and a shift register inside the loop. I want access to these values outside the loop as they are being created inside. When I connect a wire from the shift register to a display outside, it doesn't work. How do I do this? Thank you.

    I tried to create the local variable that was wired to numeric indicator inside the loop. If I try to connect this to the analog output outside the loop, the loop just starts blinking and nothing happens, am I doing something wrong? Thanks again.

  • How to avoid data selection inside the loop?

    Hello Experts,
    I am working on one performance item and I have already applied some changes to the original version.
    Now, If I compare my new program with old program, I have good improvement in performance. I am checking if I can do anything on statements that are top on the below list. I think 40% for Modify statement is acceptable after my research (Below run is updating around 20M records which is real time volume for this application).
    As we can see 34% of run time to going for one SELECT query on custom table. Take a look at below high level flow of my program to understand above select query.
    1. Select data from ZABC
    2. Select data from Variant Table (Var1, Var2, Var3 etc.., 12 in real time)
    3. Loop Variant Table
    4. Select data from X, Y, Z table for Var<n>.
    5. Populate final internal table from ZABC, X, Y and Z table
    6. Modify ZTABLE with Final Internal table data
    7. End Loop on Variant Table
    As described in the flow of the program, ZABC table data is common for all the variants and need not to fetch multiple times. Hence I am doing it only once in my program. Below is that select query:
    select rrcty ryear rbukrs racct rcntr sum( amt1) as amt1  "Like I have 32 amount fields in original query
               from zabc
                into table i_zabc
                where ryear in r_year    " Two records in ranges with I and EQ
                and rvers = '001'
                and rrcty in r_rrcty        "Three records in ranges with I and EQ
                and rldnr = 'DT'
                group by rrcty ryear rbukrs racct rcntr
                order by rrcty ryear rbukrs racct rcntr.
    ZABC table is again having huge volume of data and we are fetching millions of records with above query. That is primary reason to take long time. May be that is okay as I am already using Indexes of this table. But, I am not comfortable with it as it can reach max. memory point and through run time error. Fetch Cursor is one reliable option that I can see here, but with that, I should move ZABC selection inside the variant loop which can cause fetching ZABC data 12 times (Let me know If I am missing anything here).
    Now, third statement in my trace results, with 10% of overall time is this:
    loop at i_abc assigning <fs_abc>. 
    loop at i_table assigning <fs_table> where low <= <fs_abc>-racct and high >= <fs_abc>-racct. 
    endloop. 
    endloop. 
    6 million executions with this complex WHERE condition is causing this statement to get 3rd position in trace results. I tried below two options which are, I think, taking even more time - (I am still monitoring these options)
    1) Removed WHERE condition on LOW, HIGH and applied filter inside the loop.
    2) Removed WHERE condition on HIGH only and applied filter inside the loop.
    Any suggestions on how to proceed with ZABC selection and I_TABLE loop.
    Let me know if you have any questions on above compose.

    Since I looked at this case before, let me try some quick suggestions:
    Is table ZABC related to table X, Y and/or Z and can the selection be limited by applying those 12 selection variants?
    If yes, try a join select involving these tables that could make your step 1 obsolete and replace steps 4 and 5.
    This might also get rid of the "loop inside loop" problem. Generally, make sure that the inner table is declared as a sorted table with a key that consists of the fields as used in the WHERE-condition of the inner loop. Use secondary keys for internal tables if your ABAP release permits and the task at hand warrants it.
    Finally, look at PACKAGE SIZE option for the (join) select to reduce memory consumption.

  • HT1414 tooggling power loop - how to backup data

    My phone is toggling in a power loop between the apple icon (what you get when you shut it down) and the lock screen. I downloaded icloud on my computer to tried and backup all my data, videos, etc. I don't think I have the icloud app installed on my phone and now can't get into it to add it. Is there any way to recover my data? From what I've read, i'll have to do a factory reset.

    Hello Kim,
    Thank you for providing the details of the issue you are experiencing with your iPhone.  I understand how important it is to keep the data on your iPhone.  Have you attempted to back up your iPhone using iTunes? 
    The following article has steps to back up your iPhone using iTunes.  I recommend resetting your iPhone as described in the steps below and then trying to create a backup with iTunes using the steps in this article:
    iOS: Back up and restore your iOS device with iCloud or iTunes
    http://support.apple.com/kb/HT1766
    Once you have created a backup, I recommend continuing with steps 4-6:
    If a single application is not responding or stops responding when it opens, you can force it to close.
    If the device is unresponsive or if certain controls aren't working as expected, restart your device.
    If the device remains unresponsive or does not turn on (or power on),reset your device.
    If there is no video or if the screen remains black, verify that the device has enough charge to turn on:
    If you are using an iPad, ensure that it's connected to the USB Power Adapter supplied with the device.
    Let charge for at least twenty minutes, then see if it starts normally.
    If there is no image on the screen, press the Sleep/Wake button to attempt to wake the device.
    If the screen displays a red battery icon, continue charging the device until the battery is fully charged.
    If the above steps do not resolve the issue, or the if the screen remains black or shows a persistent Apple logo, try restoring with iTunes:
    Connect the device to your computer and open iTunes.
    If the device appears in iTunes, select and click Restore on the Summary pane. Learn more about restoring iOS software.
    If the device doesn't appear in iTunes, try to force the device into recovery mode, and then restore it.
    If the above steps do not resolve the issue, contact Apple.

  • State Diagram inside For Loop

    I created a fairly involved for-loop with a flat sequence inside of it.  The sequence had about four events that occured, and since it was kind of ugly, I thought I'd try the State Diagram Toolkit to replace the majority of the code.  When I selected state diagram from the pallete, I was outside my for-loop.  I drew up the various states/transitions, then realized that all this code needed to be inside the for-loop, but LV won't let me place state diagram-generated code inside the for-loop.  I select everything related to the state diagram, but when I drag into the for-loop, only the comments come inside.  I even tried generating a new for-loop and placing the state code inside.  No luck. Any thoughts?

    "Any thoughts?"
    Yes but not any that will help.
    1) Just modify your SD so that the exit loops back to the start while there are still things to do. Forget the outer For loop.
    2) THe observations you reported are correct. When I first discovered these limitiations I said "That sucks!". Since then I have learned a bit and have grown to love the SDE.
    The SDE is JUST (note: "just" is a four letter word around here ) a LV application that ofers a very limited GUI consisting of a picture control that then scripts (see LAVA Scripting Forum for info on scripting) your SD for you. SCripting LV code is no easy task. My experiments with scripting has shown that I have to keep a database of the contents of the LV diagram my code is developing to keep track of what is where. Well it turns out that the structure of a LV diagram is a lot like the structure of a FP in that you start with a "root" object either the FP or the BD. THe BD then has structures on it, like seq's loops etc with unlited nesting possible.
    Now the SD created by the SDE is really just a fancy while loop with an case structure and code to support the driving enum. In order for you to be able to edit the SD the SDE needs to know what is htere already so it can show the diagram. It "KNOWS" by looking at its internal DB (I believe is stored inside of VI along with the enum.ctl) of the SD. To keep the DB updated, the SDE must be used to manipulate the SD.
    Stop rambling and guessing and get to the point!
    Moving the SD is just not supported by the SDE so it can not be done. To do so would require the SDE be able to "look" at the diagram, and repeat all of its work in the new location in the diagram.
    BTW: Thank you for trying out and asking about the SDE. the more talking we do on this subject, the sooner the SDE will be updated.
    My SDE wishlist (partial)
    Add comments to diagram from SDE screen.
    Add data structures to SD (shift registers) from SDE screen.
    Add "un-do".
    Select multiple objects on SDE screen and move or allign.
    Select multiple objects on SDE screen and do "create sub-State-Diagram".
    Allow watching more than one SDE in execution highlighting at the same time.

  • Commit inside For Loop

    Hi,
    I have a query which is updating millions of records and is inside a for loop . I have issued commit inside that for loop only . Which one will be better . Should I issue the commit inside the for loop or outside it .
    Thanks in Advance,
    Rahul Guha Ray

    No it is not technically true but ajallen has a valid point. Under traditional rollback segment management reading and updating the same table where large quantities of data were changed with frequent committing was probably the number one cause of snapshot too old errors. However, there are many factors that play into this so even under traditional rollback segment management how likely you are to get an error depends: total size of transaction, total run time, concurrent access, and amount on rollback space available.
    With undo segment space management it largely depends on the total transaction size and runtime verse how much undo you have and your retention policy.
    At some point re-opening the query may indeed be a good idea. One approach is to code to re-open the query only on getting the 1555 error. Some updates however cannot be resumed easily as the update does not mark the row in such a way as the query or where clause conditions can exclude it. In cases like this saving restart information with each commit is necessary.
    A lot of different factors have to go into the decision of how often to commit.

    -- used this SQL for fetching the data using the function -
    select *
    FROM the ( SELECT cast(ABC ()
    as H_TAB) FROM dual )
    the above SQL not gives me the data in the as a normal table returns, plz suggest me how to write SQL for above case.
    Thanks in Advance,

    First try to move your obj1 and obj2 initialization outside of the for loop. Not sure if this is even the issue, but it can't be helping.
    obj1 := A_TAB();
    obj2 := B_TAB();
    for i in(SELECT AG_PROD_MOD_NR, COMM_NM FROM BV_PRODUCT WHERE AG_PROD_MOD_NR = 'E4440A')
    loop
      obj1.extend;
      obj1(obj1.last) := A_OBJ(i.AG_PROD_MOD_NR, i.COMM_NM);
      obj2.extend;
      obj2(obj2.last) := B_OBJ(i.AG_PROD_MOD_NR, i.COMM_NM);
      l_data.extend;
      l_data(l_data.last) := H_OBJ(obj1,obj2);
    end loop;
