File:reference help

how do i get the dialog box to open only once and have
multiple files downloading. I dont want to use zip or any
compression folder types.
This is for a standalone player

look at the help files for the fileReference class, it's
pretty straight forward. copy the example and try to get it to
work. then mold it into your project. the mulitple files is tricky
but there are tutorials on the web about it...

DAQmx C Reference Help file pack?

Hi all,
I'd like to download the latest version of DAQmx C Reference Help file pack.
Where can I find it?
Thanks

Solved!
Go to Solution.

Hi George,
If you download and install the latest DAQmx driver from http://www.ni.com/support/daqmx you can install it and you will get the C reference help with it. After installation you can find the C reference help at Start->(All )Programs->National Instruments->NI-DAQ->Text-Based Code Support->NI-DAQmx C Reference Help
I think, you cannot download directly only Reference Help packet for the newest version of DAQmx (9.3 now). You can download the latest DAQmx 3.x Base C reference directly (http://digital.ni.com/manuals.nsf/websearch/C4B5B92E74F160C6862574560065F8BC), but it is from 2008 June.
I hope my reply is an aswer for you question. If you have any other question, feel free to write again.

A File Reference and its evolving life!

Hi all,
I've noticed something that came as a little bit of a surprise to me, but I think I have the explanation, at a hand-wavy higher level anyway. What I have not established is if this is a 'bug' or a 'feature', and if there are any ways the following issue can be avoided at the NI function/api layer.
Consider the file open and file close function. You open a file, you use the reference to the file to write/read data, then at some point you close the reference and the close function spits out the file-path. Here are a couple of tid-bits you may not be aware of (that are easy to test):
Q1) After your application opens/creates a file and starts using the file-reference to make file writes, if an external source changes the file-name of that file... guess what will happen on your next write function call?
A1:: The write successfully updates the newly re-named file with your new data without producing an error or a warning. (At least this is the case if your program is running on a vxWorks cRIO target and the file-name is changed directly on the cRIO via an FTP browser.)
Did this surprise you? It did surprise me! -My handwavy explanation is that the file-pointer is perhaps managed/maintained by the OS, so when the OS tells the file-system to rename that file, the pointer that LabVIEW holds remains valid and the contents of the memory at the pointer location was updated by the OS.
Q2) Continuing from the situation setup in Q1, after writing several new chunks of data to a file now currently named something completely different than when the file reference was originally created, you use the close function to close the file-reference. What do you expect on the file-path output from the close function?? What do you actually get??
A2:: The close function will 'happily' return the ORIGINAL file-name, not the actual file-name it has been successfully writing to(!). This has some potentially significant ramifications on how/what you can use that output for. At this point there is a ton of room for pontifications and more or less 'crazy' schemes for what one could do, but I argue that the bottom line is that your application has at that point completely lost the ability to accurately and securely track your file(s). Yes, you could list a folder and try and 'figure out' if your file-name was re-named during writing and you can in various ways make more or less good 'guesses' on which file you in reality just had open, but you can never really know for sure.
So, what do you guys think?? Is the behavior of returning the (incorrect) original file-path when you close the handle a BUG or a FEATURE?? Would it not be possible for LabVIEW to read back the data contained in the (OS?) pointer location and as needed update the file out path data when it closes a reference? Should we not EXPECT that this would be the behavior?
Q3) Again, continuning from the above situation, lets assume we are back at the state in Q1, writing data to a (re)named file. What happens if the file is deleted by an external process? What happens to the file reference? File function calls using the reference?
A3:: This one is less surprising. The file reference remains 'valid' (because it is a valid reference), but depending on the file function you are calling, you will get error such as error 6 (binary write reports this), or error 4 (a TDMS write will report this error), etc. So as long as you don't rely on file ref-num tests to establish if you are good to go with a file-write or file-action, you should be safe to recover in an appropriate way.. Just don't forget to close the file-reference, even if the file is 'gone', the reference will still remain in memory until you 'close' it (with an error)(?I might be wrong about this last part?)
I am not sure if the above is possible on e.g. Windows, Windows would probably prevent you from re-naming a file that has an open file-handle to it, but this is definitley observable on at least vxWorks cRIO targets. (I don't have PharLap ETS or RTLinux devices so I can't test on those targets.. if you want to test its pretty straigth forward to make a simple test app for it.)
[begin rant-mode related to why I found this out and why this behavior BITES]
There are situations where the above situation could cause some rather annoying issues that, for somewhat contrived reasons related to cRIO file API performance, CPU and memory resource management, are non-trivial to work around. for example, using the NI "list folder" to listing folders take a very hefty chunk of time at 100% cpu that you cannot break up, so polling/listing folders after every file update (or even on a less regular interval) is a big challenge, and if you are really unlucky (or didn't know any better) and gave the list command in a folder with 1000's of files (as opposed to less than about 100 files), the list will lock your CPU at 100% for 10's of seconds... Therefore, you might be tempted to maintain your own look-up table of files so that your application can upload/push/transfer and/or delete files as dictated by your application specific conditions... except that only works until some prankster or well-intention person remotes in and starts changing file-names, because then your carefully maintained list of file-names/paths' suddenly fall appart.

Hey guys, thanks for turning out your comments on this thread!
-Deny Access : still able to re-name (and delete) the file via FTP browser (didn't test other file avenues). I think this is for the same reason that NI vxWorks targets (such as cRIO-9014) do not support the concept of different users with different rights, as such, everyone have access rights to everything at the OS level. Another issue for me would be that "Deny Access" does not work on TDMS file references, so even if it worked, it would not help me.
--> I strongly suspect that these things are non-issues or issues that can be properly managed, on the new NI LinuxRT targets since (the ftp is disabled by default) it supports user accounts and user restrictions on files/folders. The controller could simply create the files in a tree where 'nobody else' has write access.
Obviously nobody should mess around with files on a (running) cRIO, but customers don't always do what they are supposed to do.
As far as the 'resources' or overhead to update the file-refnum with the new information, this would not be needed to be done in a polling fashion, simply, when the file-close function is called, as part of that call it updates its internal register from the pointer data, so this should be a low overhead operation I would think? If that is a true concern, a boolean input defaulting to not updating or a separate 'advanced close' could be created?
I've included a zip with the LV2013 project and test VI's (one for tdms one for binary) that I've used. nothing fancy, but in the interest of full disclosure. The snippet is the 'binary file' test vi, in case you just want a quick peak:
Steve Bird's findings of (yet) another behavior on Pharlap systems is also very interesting, I think!!
[EDIT] JUST TO CLARIFY, on vxWorks, the re-named file keeps being successfully written to, unlike the PharLaps' empty file that Steve Bird found.

ERROR ITMS-9000: "META-INF/container.xml must contain one and only one root file reference."

Hi all,
After correcting a table-of-contents error in my .epub file, I am unable to upload it via iTunes Producer. It lists this error message:
ERROR ITMS-9000: "META-INF/container.xml in 9780615431727.epub must contain one and only one root file reference." at Book (MZItmspBookPackage)
The file has been verified and only has one root file reference in the container.xml file.
Has anyone been able to find a solution to this problem?
Thanks!

Hello Forum Users…
For those of you who have run into the upload roadblock, getting an error message similar to this:
Package Summary:
1 package(s) were not uploaded because they had problems:
          /Users/slm/Desktop/MUSIC to PICTURE for IBOOK/2012 MTP for iTUNES Bookstore/9780615600918.itmsp - Error Messages:
                    Apple's web service operation was not successful
                    Unable to authenticate the package: 9780615600918.itmsp
                    ERROR ITMS-9000: "OPS/ibooks.ncx(5): 'p50': fragment identifier is not defined in 'OPS/content9.xhtml'" at Book (MZItmspBookPackage)
Following is a "specific" fix, but the idea of the fix will help you with your specifics too.
I tried for 17 days to upload a book that looked and worked perfectly in iPAD via Preview.
After many discussions with Apple, who to their credit stayed with me over 2-3 days, I decided to play a hunch.
I went into a duplicated copy of the book and on every page, (because the error message was not telling the whole story), looked for what InDesign would call "Overset Text."
Now... the "flaw" in iBOOK Author (hint) is that it won't advise you of this "overset text" as does InDesign.
And to compound the matter, the exported ePUB document WORKS in iPAD Preview.
See Screenshots from InDesign:
Okay... Couldn't add it but it is a Warning Box that says there is overset text. (Characters which exceed the text box.)
Nevertheless, I played this hunch, and sure enough found a few boxes with the + in them. In other words I clicked on EVERY text holder and every text block in the entire document.
Where I found + signs, I simply deleted some carriage returns from the iBOOK file... (please note… carriage returns and literally empty spaces that caused the overset text) and then erased all previous copies of the Music to Picture Book on my hard drive, iTUNES and iPAD.
The result? A "text-book" upload with no snags! As my Son would say… "Victory!"
So, first make sure that you are using only PNGs, Jpegs and Movie files to iBook Specs. Then... make sure there are no overset text boxes, which you must do manually.
Enjoy & Godspeed!

The file reference 0x3000000003d66

Hi,
My hard drive has performed recently a chkdsk at boot. Since then, I cannot find an excel file named mdp.xlsx.
I have the following lines appearing in the bootex.log created after completion of chkdsk:
The file reference 0x3000000003d66 of index entry mdp.xlsx of index $I30
with parent 0x39e8 is not the same as 0x1000000003d66.
Deleting index entry mdp.xlsx in index $I30 of file 14824.
The file reference 0x3000000003d66 of index entry MDP~1.XLS of index $I30
with parent 0x39e8 is not the same as 0x1000000003d66.
Deleting index entry MDP~1.XLS in index $I30 of file 14824.
I was wondering whether this would help me. Thanks for letting me know what is the best path to follow to recover this file.

Relative file reference

OK-relatively new to the product, so bear with me. Due to
file size, I needed to link several projects together. From info I
got here, I wanted to use a relative file reference so I could copy
the .swf's to other computers. So at the end of each module, the
project is to open a new file ( ..\file\file2.htm). This method
worked fine on my computer. When I copied the necessary files to a
different computer and the first module finished, it tried to find
the file on my local drive. Can anyone help?

Try using links formatted as follows:
for files in subfolders from the calling file use
foldername/filename
for files in folders above the subfolder use
../filename

Get associated avi file from avi file reference

For normal bytestream files, there is a "refum to path" function (under File I/O -> Advanced File Functions) that will give the associated file path for the input file reference. This does not seem to work when an AVI file reference (opened using IMAQ's AVI functions) is wired ("refnum to path" returns <Not a Path>). Is there a way to extract the AVI file path from an AVI file reference?

Thanks for your help. The design of my program involves streaming video to disk (along with multiple other parallel functions, including DAQ interfacing and collection, playing back AVIs in mediaplayer, etc.). Because of this, I have multiple "engine" loops running in parallel to the user interface loop. In the UI loop, the target of the streaming video can be changed or even turned off, so I have a LV2 functional global holding the AVI file reference, which the video streaming engine checks for validity before proceeding through a loop iteration. However, in the engine, certain decisions about extra data that needs to be saved with the streaming video is made by checking the directory of the file it is instructed to write to. Therefore, a way to extract that file name from the reference in the LV2 global would be usefull. The workaround I have to use now is to store the file path as well as the AVI file reference in the LV2 global and pass them around together. This isn't that bad, but in the intrest of keeping block diagrams uncluttered with data I shouldn't need, I posted the question.

Whre can I find "Traditional NI-DAQ C Reference Help" ?

In NI-447X User Manual I have found in "Related documentation" paragraph the suggestion to read "Traditional NI-DAQ C Reference Help" for traditional NI-DAQ version7.0 and later. Where can I find this manual?

To view the NI-DAQ reference help, go to Start » Programs » National Instruments » NI-DAQ and select the appropriate file for the version of NI-DAQ that you are using.
For NI-DAQ 7.0, there are separate reference help files for NI-DAQmx and Traditional NI-DAQ, the NI-DAQmx C
Reference Help and the Traditional NI-DAQ Function Reference Help.

How can I create dynamic file references in Power Query?

Hi all,
I'm new at using PowerQuery, and so far I like it. There's one thing I am struggling with though... Once I have set up my PoweQuery connections, I don't find an easy way to change the file to which the query is connecting. I'm using it for a monthyl recurring
process, and every month the source data to query on woudl be different. The same in format/structure, but just a different dataset.
Is there a way to make the source setup more dynamic? Can I for example in a parameters sheet enter the name and path of the new source file and update the queries?
Currently the Advanced editor shows me following file reference:
let
Source = Excel.Workbook(File.Contents("Z:\Templates\EMEA\Source Data Tables\EMEA_EW_Source_Data_for_Power_Queries v1.xlsm")),
Thanks in advance for suggestions

Yes, this is something that you can do with Power Query. Here's how you can do it:
Create a table in Excel containing your parameter value. Let's say that it has one column, called ParameterValue, and one row.
Create a new Power Query query that gets the data from this table. Call the query something like ParameterQuery.
In your original query you will now be able to reference values from your parameter query by saying something like this:
Source = Excel.Workbook(File.Contents(ParameterQuery[ParameterValue]{0})),

Thank you very much !
Indeed, I was unaware of the enormous number of options that can be selected when converting a WORD file to PDF.
I went thru the settings and found the right one for embedding the fonts.

The main firefox menu that was a feature in ff4 is not showing up, but rather just the File through Help options.

I do not have the main firefox menu that was a feature of firefox 4. How do I make that show up rather than the file through help options I currently have.

Suddenly Movies and Tv Shows icon showed up, i rented a movie it worked perfectly. But the next day it happened again? only Internet - Computer - Settings icons are showing at the main menu.
i dont think it is about the location since it has worked with current settings. the itunes location is set up as US already. the time zone is selected automatically as Istanbul.
I couldnt figure out what causes this, anyone have suggestion??

Project File File References

Does JDeveloper 9.0.4 use absolute or relative file references in its project (.jpr) files, or is it a mixture of the two? I've heard conflicting stories but have personally only ever seen relative references.

Yes, I've tried this and have gotten a clean compile. However, the .dll is associated with third party software intended to add controls to a form. The form does not display in Designer though (extensive stack trace errors) which made me wonder
whether there is a downside to this approach.
