How can I use an iteration value from a "while" (or "for") loop as part of a filename?

I am using the "Write To Measurement File" function  inside a while structure and would like to incorporate the iterative value from the while-loop as part of the file name. I'm not sure how to do it. Any suggestions?

  • How can I use the output value from SIMPLE PID to write something to the serial port?

    I am working on my Senior Design Project that requires the use of incoming compressed air, propotional valves, continuous servo motors, and a serial servo motor microcontroller.  I have figured out how to send byte sequences to the microcontroller through LabVIEW using the VISA serial write function.  The motors are attached to the valves to control the flow rate.  I have created my own simple feedback system using a bunch of case structures but I realized that I am basically trying to recreate the wheel (I basically was writing my own PID VI).   I have an older version of LabVIEW (7.0 Express) and theres no way to upgrade or buy the PID toolkit, so I am stuck using the Simple PID VI.  Also, the only way the motor works is sending an array of bytes to tell it to turn on/off, direction, and speed.  Is there any way I can use the Simple PID VI in conjunction with the VISA SERIAL write function, or is there any other way I can communicate with the serial port using this pid vi?  Any information would be appreciated.

    Hi gpatel,
    you know how to communicate to serial port, but you don't know how to send a value from SimplePID to serial port???
    You know how to communicate, but then you don't know how to communicate???
    You should explain this in more detail...
    Edit:
    From you first post you know what values your motor driver is expecting. You know which values the PID.vi is providing. Now all you need is a formula to reshape the values from PID to the motor. It's up to you to make such a formula. Unless you provide any details we cannot give more precise answers...

  • How Can I get multi column values from dynamic search help?

    Hi Gurus;
    I'm using dynamic search help in my program.
    I want to get multi column values from search help. But I dont know solution for this issue.
    I'm using F4IF_INT_TABLE_VALUE_REQUEST FM.
    How Can I get multi column values from dynamic search help?
    Thanks.

    Believe it or not, the same FM worked for me in a dynpro. I will try to explain here how it works in custom screen and then you can do your work for other screens or program types. I am not going to write my actual work but will explain in general.
    I have 4 fields (FLD1, FLD2, FLD3, FLD4) and i made the search based on FLD2 and when user click on a line (could be any field), then this would bring the line on to the screens.
    There are like 3 steps.
    You have your value_tab for my fields FLD1, FLD2, FLD3 and FLD4. This is just the data that we pass into the FM. (data: IT_VALTAB type table of ZVAL_TABLE)
    Next map the screen fields into an internal table (data: It_dynpfld type table of dselc ). I also have other internal tables defined  (just to keep it straight, i will be putting here) data:  It_return type standard table of ddshretval.
    Next step is to call the function module. Make sure you have values in IT_VALTAB.
    call function 'F4IF_INT_TABLE_VALUE_REQUEST'
    exporting
            retfield        = 'FLD2'
            value_org       = 'S'
          tables
            value_tab       = It_VALTAB
            return_tab      = It_return
            dynpfld_mapping = It_dynpfld
          exceptions
            parameter_error = 1
            no_values_found = 2
            others          = 3.
        if sy-subrc <> 0.
          message id sy-msgid type sy-msgty number sy-msgno
          with sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
        else.
          perform get_selected_fields tables It_return.
        endif.
    The code within the perform GET_SELECTED_FIELDS  - We need to map the result fields after user selects it. The code goes like this. This is step is to update the dynpro fields.
    I need a internal table as well as a work area here. like,
    data: lt_fields type table of dynpread,
            la_fields type dynpread.
      field-symbols: <fs_return> type ddshretval.
    so fill out LT_FIELDS from the IT_RETURN table
    loop at lt_return assigning <fs_return>.
        la_fields-fieldname = <fs_return>-retfield.
        la_fields-fieldvalue = <fs_return>-fieldval.
        append la_fields to lt_fields.
        clear: la_fields.
      endloop.
    Call the FM to update the dynpro
    call function 'DYNP_VALUES_UPDATE'
        exporting
          dyname               = sy-repid
          dynumb               = '1002' "This is my screen number. You could use 1000 for selection screen (hope so)
        tables
          dynpfields           = lt_fields
        exceptions
          invalid_abapworkarea = 1
          invalid_dynprofield  = 2
          invalid_dynproname   = 3
          invalid_dynpronummer = 4
          invalid_request      = 5
          no_fielddescription  = 6
          undefind_error       = 7
          others               = 8.
      if sy-subrc <> 0.
        message id sy-msgid type sy-msgty number sy-msgno
                with sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
      endif.
    good luck

  • How can i get the all values from the Property file to Hashtable?

    how can i get the all values from the Property file to Hashtable?
    ok,consider my property file name is pro.PROPERTIES
    and it contain
    8326=sun developer
    4306=sun java developer
    3943=java developer
    how can i get the all keys & values from the pro.PROPERTIES to hashtable
    plz help guys..............

    The Properties class is already a subclass of Hashtable. So if you have a Properties object, you already have a Hashtable. So all you need to do is the first part of that:Properties props = new Properties();
    InputStream is = new FileInputStream("tivoli.properties");
    props.load(is);

  • How can I use mp4 audio files from my iTunes library in an Elements 10 slide show?

    How can I use mp4 audio files from my iTunes library in an Elements 10 slide show?

    AAC is Advanced Audio Coding.  Basically it's a format that sounds better than MP3 but doesn't take up as much space as a lossless format (like you'd have on a CD).  More than likely you've had that encoding turned on when you ripped your music into itunes (it's the default encoder).  Therefore your LG phone won't play them.
    You need to turn off the AAC format by going to the iTunes menu, Preferences, General (at the top), then clicking the "Import Preferences" button.  Change the AAC Encoder to MP3 Encoder.  After that you'll have to make MP3 copies of your songs by right clicking them and selecting "Create MP3 Version."  You'll get a copy of the song that should transfer to your SD card and have MP3 encoding.  Hopefully your phone will play that.

  • HT201328 My iPhone is from Japan and I want to activate it here in the Philippines because I'm living here. I have lost the original SIM from Softbank and replaced it with a new SIM card from Globe. How can I use the SIM card from Globe?

    My iPhone is from Japan and I want to activate it here in the Philippines because I'm living here. I have lost the original SIM from Softbank and replaced it with a new SIM card from Globe. How can I use the SIM card from Globe?

    You cannot. The iPhone is locked to Softbank, and only they can unlock it. Problem is that Softbank will NOT unlock the phone, as they do not offer iPhone unlocking.
    Buy an iPhone in the Phillipines.
    PS Before you go on a rant at Apple, be aware that Apple does NOT unlock phones and they do not set unlocking policies. The carriers (Softbank in this case) set the unlocking policy.

  • How can I findout the coulm value contains 0 through 9 for the table

    could u plz suggest me how can I findout the coulm value contains <> 0 through 9 for the table...

    Well I am going to give it a shot, because I believe I am looking for the same thing.
    I have a value that is of type varchar2. How can I determine if it has special characters or alpha characters in it? In other words, I only want the value to consist of numbers. (Initially it had been thought that Letters would be used as well, but now they just want numbers and the datatype of the column cannot be altered since there is data in it.)
    I have gotten this far, but I do not know what else I can use besides '[:alpha:]'? I cannot seem to find this documented anywhere...I can find the regexp package reference, but not the character classes...
    select regexp_instr('1a23456', '[[:alpha:]]',1,1,1, 'i') x
    from dual
    This works fine = returns 3, so I know there is an alpha character.
    select regexp_instr('1$23456', '[[:alpha:]]',1,1,1, 'i') x
    from dual
    This returns 0 - what do I need to change so that it detects the '$' and returns 3?
    Thanks!!

  • How can i use my smart TV as a second monitor for my Power mac (2010) via HDMI cable? i've made the connection but no options show in system prefs display.

    How can i use my smart TV as a second monitor for my Power mac (2010) via HDMI cable? i've made the connection but no options show in system prefs display.
    the computer:Mac Pro, Mac OS X (10.9.5), 2 x 2.66 Ghz 6-Core intel Xeon
    the TV: LG Smart tv

    The Mac uses a highly-parameterized universal Driver for every display. The parameters are set at certain times when a query is sent to your display. The display MUST answer with its name and capabilities, or the screen stays dark. A TV set that is off or "not paying attention" because it is set to a different port when the query occurs will rarely answer, and so will often remain dark.
    You can use tools in the System Report to see whether your display has been detected at all. If it has, the report will look something like this, but its name will appear:
    The times when the query is sent are:
    • at Startup
    • at wake from sleep
    • when the Mac-end of the cable is inserted
    • when using the Option ( Detect Displays ) button in displays preferences

  • How can I remove the background sound from the headphone jack for my MacBoo

    for my MacBook Air problem adding music intensifier (Panasonic ST-HT1000) to give it an unpleasant sound background that sounds like a whiz, it's not so loud, but it is an unpleasant .. after a short time can get used to, but the fizz does not pass, however, believe that it is a big problem.
    Further I notice that when MacBookAir disconnected from the charger, it remains quieter sound.
    At first thought that the headphone jack (3.5 mm Headphone:
    Connection: 1/8-Inch Jack) or wiere have problem, but tried 3 different cables, but that does change enything, the problem remains.
    When I added iPhonu3GS playing - the background sound were not, then everything is OK!
    How can I remove the background sound from the headphone jack for my MacBook Air 13?

    There is no way to bring that up unless you have it typed in a document. You can use My Support Profile to find a list of serial numbers that have been purchased or registered with your Apple ID.

  • How can I use the color adjustments interface that shows up for camera RAW on jpeg files?

    How can I use the color adjustments interface that shows up for camera raw on other files types? The HLS controls had the secondary color adjustments (6 colors instead of the 3). Plus, it had same vibrancy and a better Curves interface. Yesterday was the first time I imported raw into Photoshop CS5 and I got that really cool interface. What is that? Can I use that on other file formats?

    Actually I am using the Tradional Chinese Version, when I try to edit the jpg file with camera raw, the system shows that there is no camera raw plug-in. The cmaera raw never work.

  • How can I get the edited value from the editor in JTable

    I have a JTextField added as an editor to a cell in JTable.
    I value gets changed when I press enter.
    but in actionPerformed of the JTextField when I say
    String txtEditorValue = txtEditor.getText();
    I am getting the old value. How can I get the edited value? Thanks.

    Hi,
    I guess, your understanding of how JTable works together with its models is not good enough - for example the method getTableCellEditorComponent(...) of the TableCellEditor interface is used to get the component, that should be used as editing component - its second parameter is a value that should be used to setup the editing component - it is normally not the editing component itself.
    JTable uses an underlying TableModel to store the cell values - if you have edited a cell, JTable gets the value of the editing component by itself and stores it in the TableModel using its setValueAt(...) method. To retrieve this data you only need to query the TableModel using row and column of this cell as parameters
    say jt is your JTable, and row and column are the row and column of the cell - so to get the value, simply use
    Object obj = jt.getModel().getValueAt(row,column);
    if you know, that there is a String in this cell use
    String str = (String) jt.getModel().getValueAt(row,column);
    The editor component is used for the view of the JTable - you only want the data, which is stored in the model - you don't have to deal with the GUI components in this case.
