Reading Waveform (.hws) files from Analog Waveform Editor into LabVIEW causes read errors

Hi Gang,
In my application, I want to create files Using the Analog Waveform Editor and then, through LavVIEW, play them out through an D/A.
I've not been able to read the .hws file into LV. I've tried two methods:
Using the Read Waveform VI in the Waveform palette, yields Error -1821.
I looked in the knowledgebase and found the article "Using the Analog Waveform Editor and HWS Files with Multifunction DAQ Devices" That recommended using the HWS VIs that are a part of the FGEN driver. I tried that and get an Error -21515.
The file I want to read is quite small, only 20 samples. Is there some limitation on .hws files or the Waveform Editor I'm not aware of?
I've attached the file if anyone is willing to experiment. I had to change the extension from .hws to .txt to be able to attach it.
All responses will be appreciated.
Thanks,
Roger

Interesting. I tried to look at your file with the low level read .hws file vi's and I too got error -21515. So I tried the NI-HWS express load.vi and it looks like it worked. I'm not familiar with the analog waveform editor...does it store using the dynamic data type? Oh I converted the dynamic data to 1d array of waveforms using the convert from dynamic data.vi.

HELP! How can i restore/recover files from Bootcamp with Boot Failure - Missing operating system error?

Hi,
I am having a few problems with bootcamp on my imac. When i tried to move the bootcamp partition on windows 7 into free space, it crashed and turned off. Ever since i have had the error 'Missing operating system' and it fails to boot. I have some very important files on the bootcamp partition. Is it possible to recover these files or even to restore the bootcamp partition to it's original state? I do not have a backup of my bootcamp partition. Another problem i have is that ever since i tried to expand my macintosh HD partition into free space, when i hold alt while booting up (to choose which partition to boot like i normally do), the bootcamp partition has stopped appearing. This means that i cannot even boot the windows 7 bootcamp partition anymore!
So basically here are my 2 questions:
How can i restore/recover files from Bootcamp with Boot Failure - Missing operating system error?
How can i make the Bootcamp partition appear in Startup Disk and when i hold the option key while starting up my computer to allow me to boot windows 7?
Any solutions are very much apreciated!
Thanks!
I know that bootcamp (disk0s4) hasn't been fully deleted since it appears in disk utility (i cant do anything to it though)
And here is the error i see when i try to launch bootcamp (back when i was actually able to boot up bootcamp to the error screen)

WinClone 3 is OS X and saves Windows image it makes for restore - that should work but you will have to try and you would need to make a new image unless it also works with a native Windows system restore image. It is now supported and has come a long way.

Paragon Clone OS works and does disk-to-disk clone just like CCC you end up with two bootable drives. But does not work with your setup. It would let you clone and move your Windows install to an SSD or another disk drive though and be bootable.
During its clone process it checks for errors which is very helpful and lets you know - something CCC and others should adopt more of.

I wish for our/my sake you had re-read and rewritten the long 'story' and broken it into a brief list of facts we needed.
OS X
Windows
Backup (though external is much safer) and you want bootable OS X clones as well as TimeMachine

There are a number of things to do like chkdsk and others as well as Windows DVD to do automatic system repairs and find out why.
AppleHFS - the abilty to mount and read HFS volumes can be notorious.
I would rearrange and redo your storage setup and how you use the 4-5 internal hard drive bays.

Drag and drop files from outside of DW into DW Files Window

When I was using Dreamweaver CS for Windows, I could drag and
drop files from my desktop directly into the Files Window of
Dreamweaver. But I can't do that in the Macintosh version. Am I
doing something wrong, or is it not supported?

No. This is not supported.

I installed the InDesign CC Testversion and now i try to open INDD-Files from earlier Version. Always i get the error "This file is made by an earlier Version...." but it´s CC that is the latest Version. What is the problem ? Should i have to convert the files ?

Adobe has been using confusing version names for at least five years.
There are now two versions labeled CC, version 9 and version 10 (also known as CC 2014). Version 10 is the latest, and if you attempt to open a version 10 file in Version 9 that is not fully patched you will get an error message telling you that the file cannot be opened. The latest patch for version 9 should use a cloud-based service at Adobe to convert version 10 files to IDML and allow you to open that.
I suspect you may be using an older operating system. Version 10 requires that your system runs at least OS X 10.7 or Windows 7 SP1 and if you are not it will not even be offered to you.

Convert DV-AVI file from the sony camcorder into MPEG2 with time and date

I want to capture or convert a raw DV-AVI file from the sony camcorder into MPEG2 format...this i want frame by frame conversion and i also want the metadata i.e. time and date to be captured at the same time when the conversion is done....so i want to know that which is the JAVA tool available for that ?

I read a whole bunch of random responses to similar questions ... here's some
Try opening the file in iMovie
Try changing the filename extension to ".dv"
Here's an interesting one: http://discussions.apple.com/thread.jspa?messageID=6172027
But my personal favorite idea is to just re-export the file from a PC in a better supported codec
(BTW If you don't have access to a PC then you can easily install Bootcamp on your Mac .... you can even download a free prerelease copy of Windows 7 to install on the Bootcamp partition if you're quick)

" When I did this, my library showed all the music I have "purchased" from itunes but did not have the music that I downloaded a long time ago through itunes from my old CDs."
Correct.

Copy it from your old computer or your backup copy of your old computer.

Copying file from a local computer into mapped LAN share.

Hi,
Flash itself has no filewriting capabilities other then the
SharedObject
stuff.
But why can't you call a php script? You could install
apache, PHP and
MYSQL on the computer running the Flash app and get it all
into the
database in one go.
Otherwise you either need to get going with AIR (Adobe
Integrated
Runtime), or use a wrapper application like Adobe Director
(which has
tons of ways to write to file through it's plethora of
Xtras.) Director
may be 'a bit' hard on your budget if you only use it for
this purpose
though.
The XMLSocket is for connections to some server, local or
remote, not to
a file.

I need help! when I am importing my NEF files from my D3300 camera into lightroom 5 and try to use the "copy as DNG" button I always get an error message saying that "saying the file is not recognized by the raw format support"

I need help! when I am importing my NEF Raw files from my D3300 camera into lightroom 5 and try to use the "copy as DNG" button I always get an error message saying that "saying the file is not recognized by the raw format support". The whole purpose of that button is so that the file can be recognized... How can I make the "copy as DNG" button work as it is supposed too?? Thank you

Thank you for responding. So I essentially will never be able to use that button in lightroom 5? do I need to get LR 6? Will there ever be an update for LR 5 that will enable me to use it?
Does DNG Converter work within LR or do I have to upload pictures to my computer and then make a second copy in DNG format. and then go into LR and use them?
Thank you @dj_paige

How do I import files from My Canon XF300 into FCPX

Is there a plugin for FCPX Ver 10.0.7, I found one for FCP 7 but that doesn't work. I also downloaded The Canon XF Utility but although this opens the clips from the camera I am unable to get the clips into FCPX.
Fred,
Sorry, I mis-spoke. I do have Canon Utility installed on my SL machine, but have used it mainly as a file review interface and as a backup utility. My MXF files are then brought in via Log & Transfer in FCP 7, which requires one of the plug-ins (and as you noted, does not work with FCPX).
In the majority of situations I'm ingesting on location to a MBP running Lion. In that case, I have the option of importing them either into FCP7 or FCPX.
A came across this hack for getting the Canon plug-in to install on SL. It looks straightforward but I haven't tried it, so if you do, proceed at your risk. As for me, my plans are to partition my drive later this month and boot from both 10.6 and 10.7 as necessary.
Good luck.

How does I read a HWS file that contains 2 traces, in labview? (error -21508)

Dear experts,
I have been using a PXI-5105 acquisition card to save data from 2 channels at the same time (coming from different sensors).
Up to now I have been reading the files in Matlab, taking into consideration the group name, the trace name and the coefficients of each channel. I was able to do the post-processing of the data in Matlab. I attach an example of the kind of files I'm handling if it helps, inside a zip.
Now I would like to implement this post-processing (FFT, etc.) in Labview. I have tried to use a couple of examples such as "hws_low_level_read.vi" or even the HI-HWS Express load utility to check the file, but it seems difficult to read it because of the 2 channels saved inside the same file.
The error -21508 appears at the "niHWS Get Wfm reference.vi". That refers to:
Error -21508 occurred at niHWS Get Wfm Reference.vi
Possible reason(s): NIHWS: There is no group in the file that matches the provided group name
And it seems odd to me, as I'm using the same name for group (wfm_group0) and trace(vector0) than I was using in Matlab.
Anything I'm missing? Any hint on how to read it in any way?
Thanks you very much in advance for your help
Best regards

Dear all,
I have been struggling with that problem today and I just wanted to post here how I have finally found a way to read the data.
It is so easy that I'm a bit ashamed, but I think it is worthy to answer in case anyone would need it.
The "niHWS Get wfm Reference" is asking for a Group Name and for a waveform name. I have used the "niHWS Get Group Name" and the "niHWS Get wfm Name". Both have direct outputs (strings) with the information that "niHWS Get wfm Reference" understands. You can directly link them.
But actually, in the reading of the data I found that the group name doesn't need to be fulfilled and the waveform name is "0" or "1" in cae you have 2 channels.
So, you see, it was very easy for my HWS file: put a control and select "0" or "1" for waveform name. The simpler the better, jejeje.
I hope it helps. And sorry for opening the question I'm now answering myself. I was completely lost yesterday.
Best regards
