Error while opening an excel file via labview

i don't know why i get this message,then the excel won't open at all

It appears that the New Report .vi only accepts the .xlt template format and not .xltx as one would commonly expect. I am currently working to determine for sure that this is the case, but it does run (mostly) properly on my end if you make that change.
When I say mostly, I mean there are a couple other minor issues with your code. First the first frame of your sequence structure is really accomplishing anything. If your intent is to open a reference to the excel template, there is no need because the New Report .vi does it automatically.
Second, you will need a file path of some sort wired in to your Save Report to File .vi or else you will get a different error message after fixing the .xlt issue. I am currently researching whether this should be marked as a required terminal instead of recommended so that it not being wired would result in a broken run arrow rather than an error.
Let me know if these suggestions resolve your issue, or if I can provide further input on what you are doing in your first frame. I will touch base again once I determine whether these are expected behaviors or bugs.

  • Error While uplaoding a EXCEL file in Web dynpro - HR_KR_XSTRING_TO_STRING

    Hi,
        I am getting an error while uploading an excel file in web Dynpro application. i am using the HR_KR_XSTRING_TO_STRING this function. I am getting the following error message 'Unable to interpret    as a number'.

    First of all, are you sure you know what you are working with here.  If this is standard Excel file in the Microsoft binary/propriatery format there is not function module or class in ABAP that can magically just transform this to a character string.  You should search the forums as this has been discussed extensively.  On that topic, please also do not post duplicate threads.  I have already locked your other thread with the same basic question.
    Instead of the binary/propriatery format of Excel, the file should be saved on the client as a text based format - like XML or Text Tab Delimited. You can then use several different options on the server to convert the XSTRING to STRING and process the content (becuase it was text based to begin with).  You could use CL_BCS_CONVERT, the function modules in the function group SCMS_CONV, or the class CL_ABAP_CONV_IN_CE.

  • How to open an excel file from labview?

    I tried to use "open file" vi from File I/O -- Advanced file functions to open an excel file in LabVIEW. Why the excel file wouldn't open after I run the program?

    In addition to ActiveX, you can also manipulate Excel data files using the Windows ADO interface - a technique that is more robust, faster and IMHO easier. Do a search on the forum as there have been several threads within the last week or so discussing this very thing.

  • Microsoft Forms and Microsoft Visual Basic while opening the Excel file

    Hello,
    I have issues with 2010 64 bit Office Pro Plus Excel. Whenever I open an Excel file (97-2003 worksheet) which has macros then I get below 2 errors in sequence.
    Please note that all macro settings are enabled and below are my system configs.
    Win 7 Ultimate 64 bit,
    MS Office Pro Plus 2010 64 bit with SP2.
    Googled all and tried but in vein and also note that I dont have any .exd files under ../forms to delete. Please help.
    Please note that for others with same system config/office versions and same 97-2003 worksheet it works so issues is only in my system.
    First Error
    Microsoft Forms
    Could not load an object because it is not available on this machine.
    Second Error
    Microsoft Visual Basic for Applications
    Compile error in hidden module:  MainUtilities2.
    This error commonly occurs when code is incompatible with the version, platform, or architecture of this application.  Click "Help" for information on how to correct this error.
    Thanks.

    Your macro's will not run in a Office 64 environment only in a 32bit environment. The 64bit environment has a whole different setup and macro's created in an earlier 32 bit environment will stop working.
    So if you want to use them in a 64 Office environment you have to rewrite the macro's.

  • How to stop prompt while opening an excel file in new window

    hi all
    i made one table in jsf and i am having two icons corresponding to each row one for open and one for save. on the click of open i am calling web services getting the excel file and opening it but it is happening only . when i choose to open option from the prompt which comes when i click on the link. how to remove that prompt so that on click of the open it should directly open the excel file. plzzzzzzzzz hepl

    in the url of the new page that you are opening add --> &RetainAM=Y at the end.
    Following points should be useful :
    Suppose ,you have to open a new window from your page by clicking on a link or a button and after opening, when you click on any button in the parent page, if you are getting a session out error… try the following solutions:
    1.     Add retainAM=Y in the destination URI of the button or link
    2.     If you have the back button handling in your code, ensure that…
    if (!pageContext.isBackNavigationFired(true)) is written instead of
    if (!pageContext.isBackNavigationFired(false))
    3.     Also ensure that the trasaction name is exactly same in both startTransactionUnit and end TransactionUnit
    TransactionUnitHelper.startTransactionUnit(pageContext, "sameName");
    TransactionUnitHelper.endTransactionUnit(pageContext, " sameName ");

  • Problem while opening the excel files

    Hi
    In my system , i have excel reports in my server disk . And i am opening the excel files through an action class like /viewReport.do?id=23 .....and thus from the action class i open my excel file .
    After opening one excel file , i try to open another excel by clicking that link , then my system often hangs else excel shows an error saying "a report with name viewReport.do is already open " even though both of these files are different on the server
    How can i avoid this ??
    The reason why i am opening the excel file through an action class is , i need to perform some operations before opening that excel report
    i tried by setting the
    response.setHeader("Content-disposition","attachment; filename=myWorksheet.xls");
    and i kept on changing the names but that doesnt work
    Can any one let me know how to go abt this ??

    Hi Sir,
    I found you posted the issue in the
    APS.NET forum, and you seems use some code to open the file. Have you tried the last link in the thread?
    Then, let's do some test to narrow down the issue.
    I notice that you are using Office 2010, does the issue occur only with 'Reachlocal.xlsx' or every existed file?
    If every Excel file has the issue, please try the following methods:
    Open the file in
    safe mode.
    Repair Office 2010.
    On the other hand, this problem might be caused by malware on the affected machine. There are now two known variants of malware which causes this problem: Win32/Crilock.A and
    Win32/Buma!rts. They have both been identified as a new family of
    ransomware.

  • Why does TDM Importer start up when I open an Excel file in LabVIEW, and how can I stop it?

    I have a new application using LabVIEW 2012 SP1.  I open an Excel file using the Report Generation toolkit and when I do so, a small TDM Importer window pops up on top of the Excel file.  
    How can I prevent this?

    Hi Steve,
    The TDM Importer pops up because the report generated in LabVIEW is in the TDMS file format.  TDMS is a binary file that requires an importer to make sense of the binary data and translate it into an Excel spreadsheet.  As per this white paper, the appearance of the floating toolbar is expected behavior:  http://www.ni.com/white-paper/5874/en/
    To the best of my knowledge, you cannot get rid of the floating toolbar unless you uninstall the add-in, in which case you probably would not be able to open your LabVIEW-generated reports.  However, as of Excel 2007, the toolbar is embedded in the "Add-Ins" tab instead of floating on your spreadsheet.  You can see how the toolbar looks as of Excel 2007 in step 6 of this white paper:  http://www.ni.com/white-paper/5885/en/
    If there is a way to embed the toolbar in Excel 2003, it would be the exact same way you would embed any other floating customer toolbar in Excel.  In other words, I don't think this has anything to do with the fact that it's NI's add-in.  This is just the way Excel 2003 and earlier treats add-in toolbars.  Someone on these forums may well know a way to embed it (perhaps a macro?), but you may have better luck contacting Microsoft.  I'm not sure whether it's even possible for a user to embed the toolbar.

  • BYMONTHDAY is causing the error while opening the ics file in outlook when event is exported from SharePoint Calendar

    Hi All,
              I am trying to parse the SharePoint recurrence data to get the RRULE for the ics file the RRULE parsed works fine for Yearly and Daily but it causes error when opening the ics file for the Monthly and
    weekly recurrence recurrence. I have opened the ics file in the notepad and observed that the BYDAY and BYMONTHDAY causes the problem. If I remove the tag the file opens fine but with wrong recurrence pattern.
    Any help will be appreciated.
    Regards

    Ajeet,
    I see that this is an extremely old post, but I thought I would refresh it with a bit more info.
    I wish I had found this post a few days ago.  I realized the same thing as well.  I don't quite understand the reasoning behind requiring the by day date must be the same as  the event date.  Another thing with rrecurrence is that if
    you pick a day of the week for a recurrence (i.e. Friday), then the start date must also occur on a Friday (I am just casting it as the first Friday of the month).
    I have come into this same issue with the BYMONTHDAY.  I am currently working on trying to configure an .ICS file to allow for multiple monthly recurrences, but it appears Outlook does not support multiple days within an event (determined by trying
    to create an even in Outlook and picking the recurrence option).  It seems that you are only allowed to have an event on (for example) every Friday of each month, or the (x) day of each month.  You cannot set any other occurrences of any other day
    within the same ICS file.  Hopefully someone else will find this information useful.
    Cheers,
    Tracy

  • Problem while opening an excel file

    Hi
    I am trying to open an excel file by clicking a link where it goes to action class and then sets the content type to excel and I am opning it from there�but the strange thing is that a file download opens with open/save/cancel but in the same window but it is showing a warning in the dailog box(windows warning which comes as an exclamatory mark) saying "This type of file could harm your computer if it conatins malicious code" and on cliking open it shows a dialog saying "Could not open http://localhost:8080/context/myaction.do?fileName=3.xls" .Dont know why its trying to opne my action url rather than it should look for 3.xls in my folder
    Any clue on this would be helpful

    Hi,
    Try saving the file and then check if extension is xls. If you are not able to do anything (open, save), try to call the same application (file), from other machine, as sometimes browser gives the problem.
    If still problem occurs, then copy paste the code for setting the content type here.
    Best of luck,

  • How can I creat or open an excel file in labview?

    I am using Labview 7.1 and report generation toolkit. I got the example code from this address :"Creating a report in Microsft excel using the labview report generation toolkit"
    But seems this example only can creat report when the excel file exist, otherwise it will get error code 7.
    How can I creat a new file if it doesn't exist and open the file if it exist? Can I creat a report without openning excel because I need to creat more than one report and check it after the test.
    Thanks

    Simply use the "Open/Create/Replace File.vi, and wire a constant "Create / Replace".
    Wire a path/filename and make sure the name ends with the extention .xls
    If you have multiple lines (likely), place aech line in an array and use the "Array to Spreadsheet String.vi" before sending it to "Write to file.vi". Don't forget to close the file.
    Hope this helps..

    Regards,
    satish.

    You are going to need to provide more details about this shell script file you are executing and the environment it is in. Beyond being on a Windows box, you have provided none of those details.
    If the SQL statement will execute cleanly in SQLDeveloper but not your script, then the issue lies in the script. How do you know the error is that SQL statement? Can your script even "select * from dual;" successfully?
    Also, SQLDeveloper (which I don't use) may contain its own libraries for accessing the DB. You probably should consider upgrading to a SQL*Plus client that is at least the same version or later as your database.
    Note:
    As I recall, xmlgen in 9.2 is now a synonym for dbms_xmlgen. You should change the package name accordingly [url http://docs.oracle.com/cd/B10501_01/appdev.920/a96612/d_xmlge2.htm#1010709]dbms_xmlgen.getXML
