Read From Measurement File doesn't work

I am using LV 8.0 and have a daq program that writes data to a .lvm file every two seconds. When I use the Read From Measurement File block the resulting waveforms have dt set to 0 rather than 2 as it says in the file. All the y values are good but I have to ue the Build Waveform function to set dt to 2 but I should not have to do that right? I can see dt is 0 using a probe on the output of the Read Measurement Function.. I have attached a sample .lvm file but I have changed the extension because this site would not accept a .lvm file!

Jeff B,
Sorry for the delay, I have been travelling for a couple of weeks. I took a look at the profile and your are right, it was modified incorrectly. When the data are taken and stored as a CSV file using Write to Labview Data file, the program always sets the sample number to 1 because it is being called to append one sample each time through the timing loop. Since the number of samples is wrong, I was modifying the number aftewards to get the read to work. After your comment, I used jedit to modify it rather than excel and it worked. I could change the program to store the data only once after the run is finished to eliminate having to mess with the data. I don't know how else to fix it.
Thanks,
Phil

Problem with ArrayLists and writing and reading from a .dat file (I think)

I'm brand new to this forum, but I'm sure hoping someone can help me with a problem I'm having with ArrayLists. This program was originally created with an array of objects that were displayed on a GUI with jtextFields, then cycling thru them via jButtons: First, Next, Previous, Last. Now I need to add the ability to modify, delete and add records. Both iterations of this program needed to write to and read from a .dat file.
It worked just like it was suppose to when I used just the array, but now I need to use a "dynamic array" that will grow or shrink as needed: i.e. an ArrayList.
When I aded the ArrayList I had the ArrayList use toArray() to fill my original array so I could continue to use all the methods I'd created for using with my array. Now I'm getting a nullPointerException every time I try to run my program, which means somewhere I'm NOT filling my array ???? But, I'm writing just fine to my .dat file, which is confusing me to no end!
It's a long program, and I apologize for the length, but here it is. There are also 2 class files, a parent and 1 child below Inventory6. This was written in NetBeans IDE 5.5.1.
Thank you in advance for any help anyone can give me!

BalusC -- The line that gives me my NullPointerException is when I call the "DisplayProduct()" method. Its a dumb question, but with NetBeans how do I find out which reference could be null? I'm not very familiar with how NetBeans works with finding out how to debug. Any help you can give me would be greatly appreciated.The IDE is com-plete-ly irrelevant. It's all about the source code.
Do you understand anyway when and why a NullPointerException is been thrown? It is a subclass of RuntimeException and those kind of exceptions are very trival and generally indicate an design/logic/thinking fault in your code.
SomeObject someObject = null; // The someObject reference is null.
someObject.doSomething(); // Invoking a reference which is null would throw NPE.

Read From Binary File doesn´t work on MCB2400 in LV2009 Embedded ARM

Hello,
I try to read a Binary File from SD-Card on my MCB2400 Board with LV2009 Embedded for ARM.
But the output is always 0, if I use my VI on the MCB2400. If use the same VI on the PC it works fine with the same binary file.
The
access to the SD-Card on the MCB2400 works in other cases finde, if I
try to read from a text-file it works without any problems.
Are thre any constraints for the "Read From Binary File"-Node in Embedded in comparison to the same node on PC ?
I have noticed that there is also a problem
with the reading of textfiles. If the sice of the file is about 100Byte
it doesn´t work anymore, too. I can´t understand it, because I read
always just one Byte. And even if the implementation in Labview is so
bad that it allways reads the total file in the ram it sould work. The
MCB2400 has 32MegaByte RAM, so 100Byte or even a few MegaByte should
work.
But this doesn´t seem to be the Problem for the Binary-Problem. Because even a 50byte Binary-File doesn´t work.
bye & thanks

SD_Card_Read-test.vi ‏12 KB

Hello,
thank you for your Help.
But I just want to read a Binary File, which is build by another program. And this is coded with 8Bit (like a normal Binary File) and not just with 7Bit (ASCII). So the workaround doesn't work in my case.
I posted the Test-VI in my first post (here once again as picture). And it works fine on the PC, but if I try it on my MCB2400 the "Read Form Binary File" Node doesn't work.
And it is also possible to open the Bin file with the "Read Text File" Node and see the cryptic content of the Bin-File. So the Problem seems to be in the "Read Form Binary File" Node.
bye & thanks again

I am trying to download a file from Safari. It doesn't work.

I am trying to download a file from Safari. It doesn't work. It always comes up with a notification saying, 'Safari could not download this file'. Why does it do that? More importantly, what should I do? how do I download it?
Thanks to the users who reply to this. It will help me a lot.

What type of file is it?
If safari can't natively open the file, or there is no App installed thatr can, it won't download.

Windows Easy Transfer (WET) Issues with External Hard Drive - "Can't read from the source file or disk"

I work for Office Depot, in the tech department. Basically, one of our associates was supposed to do a data backup, and re-install Windows 7, then transfer the files back. He used Windows Easy Transfer and compacted everything into a 163 GB file.
Now comes the hard part. When we try to put it back on his computer ((drag-and-drop to the desktop) which has been wiped back to factory settings using the recovery partition), it stops at 79.5 GB remaining (you know how it doesn't give you a % of completion,
it just shows how many GB are remaining) and then says "Can't read from the source file or disk" and gives you an option to try again, or cancel. It gets hung up on the same point each time.
Normally, this wouldn't be a huge issue, but the contents on the drive are his wife's architect blueprints and interior design stuff, along with wedding photos, etc, which are the only copies they have. On top of those, they have court documents and other
important files that we are unable to access now.
I wasn't involved with this transfer, so I'm trying to clean up the mess as best I can. I remembered that the customer's wife was Russian, and had some files typed with a Russian keyboard, so on and so forth. I wonder if that's the issue? If not, I really
have no idea how to manually extract things from a ".mig" file, or how to diagnose what area is potentially corrupted.
In light of this situation, we tried using "Recuva" to recover the files post-wipe, but everything was corrupted or unable to be opened, and it also extracted and recovered all of the "useless" photos, such as the skype logos, up and
down arrows for browsers, etc (it was 160,000+ photos).
Trying to avoid a potential lawsuit, unhappy customer, and costing the company lots of money to see if professionals can get into this external hard drive.
Other relevant information:
We used a Toshiba 500 GB (465 GB) external hard drive.
Customer's computer is an HP Pavilion P6000 Series (Model No. p6520y) running Windows 7 Home Premium 64-bit Service Pack 1.
Any other information that is needed can be provided, thanks in advance, and hopefully we can find a solution to this issue quickly!

I think there's a lack of understanding somewhere.
"If you even can't start the process, please unplug it from your new PC. Then head back to your new computer and plug
the external drive back in to your new computer. "
Unplug from new, head back to new, plug it back in? That doesn't make much sense! Haha.
I knew what you meant though, somewhat. When I search through the drives after clicking yes (Has windows easy transfer
already saved your files blah blah blah) I click on the transfer file and it says "Windows Easy Transfer could not open the file".
Rather than drag-and-drop the file to the desktop, I now tried to double-click on the file itself while it was plugged
into the computer. It opened, and it started transferring until it was about 70% completed, and then an error popped up saying "WET can't open the easy transfer file, make sure your USB device is plugged in or check your internet connection".
I checked, and the USB hard drive's light wasn't on. Now, I unplug it and plug it back in, and the light comes back on,
so I click Retry, and it resets the bar back to nothing and says "Transfer time: 1 minute".
Rather than continue trying, I clicked "Cancel" instead of Retry, and it says "Your transfer did not complete successfully."
It says to click "view report" for more information, but there's no "view report button".
At the moment, I am scanning the External Drive for bad sectors using the check disk tool in properties. It's frozen
at "0 USN bytes processed".

The data of CS5 was created at another PC. I installed Cloud version into two different PC. One has had the site data since dreamweaver CS5 and it works correct in Cloud version. Another PC got the site data from remote server and it doesn't work correct. <navi> and linked image are broken.

This implies your site is not properly defined in DW. Go to Site > Manage Sites.
Or simply go to your other installation of DW and export the site definition file from Manage Sites.
Save it to a flash stick or other removable drive. Then import the STE file into your 2nd installation of DW.

Examine and repair iphoto library files doesn't work?

examine and repair iphoto library files doesn't work?

As a Test:
In the Source account - create a new library and try share it instead.
Hold down the option (or alt) key and launch iPhoto. From the resulting menu select 'Create Library'
Import a few pics into this new, blank library. Is the Problem repeated there?

Getting repeated values when reading from a text file.

I need to read from a text file. When the token encounters a particular word (command) I need to read the next line and perform some actions. However, this part is working but it is repeating the values again and again until it encounters the next particular word (command). Hope that someone will help me out, as always when I posted a problem in these forums.

Thanks for your interest. Please ignore SetOperations class, it is just the class containing the methods and it works correctly since I checked it without reading from a text file. I marked the part where I think lies my problem in class SetTestOperations.
The information in the text file is as follows:
membera
Hillman
membera
Skoda
membera
Honda
membera
Toyota
and the result is:
[0] Hillman
Number of set members: 1
[0] Hillman
[1] Skoda
Number of set members: 2
[0] Hillman
[1] Skoda
[2] Honda
Number of set members: 3
[0] Hillman
[1] Skoda
[2] Honda
[3] Toyota
Number of set members: 4
instead of just one set:
[0] Hillman
[1] Skoda
[2] Honda
[3] Toyota
Number of set members: 4
Hope it is easier to understand like this.

Post Migration from SP2010 -Attach File Button not working in any list new/edit forms

Hi,
We have migrated the SharePoint 2010 farm to Sharepoint 2013 on last saturday and we are noticing an interesting issue after the migration .
On any custom list on any web application ,When we create a new item,if we click on attach file button in the ribbon,nothing shows up on the screen.
In the browser Dev Tools its showing an error message as "Cannot read Property style of null".
This is happening on a javascript (form.debug.js) on line No : 5276
(document.getElementById("partAttachment")).style.display = "block";
There is no element rendered in html with id "partAttachment",which is causing this error to happen.
Solutions tried are
1) Modified the List Advanced Settings to disable and enable the attachments ,which did not work
2) Ran the Sharepoint Configuration wizard which did not fix
3)Tried reset the site definition for all pages in the site from site settings
4) Deactivated and activated all the activated features in the site collection
Its an OOB List New Form,no customizations has been done.
Similar error occurring with List Edit form as well
when you click on the List Item in the List default view when you navigate to the list and when you click on attach file,a popup dialog to upload attachments appearing,However its not working when you
navigate into the list item and tried to upload attachment.
Please help if any Solutions / thoughts

Hi Christopher,
Thanks for your reply,
Farm Information
OS: Windows Server 2008 R2 SP1 Enterprise
SQL: SQL 2008 R2 SP2
SP -SharePoint 2013 with no CU applied
Method,we used is restored the content DB from SP2010 and attaching to SP2013 SQL Server
Site Collection is in 15 mode
It happens on new site collection even though its not migrated site.
Server is 16GB RAM 8Core Processor
If we create a new form from designer,attach file link is working
OOB New form.aspx is having List Form webpart
Custom New Form.aspx creaed with designer has data form webpart
if we create a new sharpoint site collection in 2010 mode,its working fine without any issues
Interestingly,all the javascript files loading were debug.js,Not sure how its loading all debug.js files

Cannot read from the source file or disk

I had to get a new hard drive for my Satellite A665 old one kept freezing up; had a recovey disk from Geek Squad when I got it but they did not work. So I ordered a Recovery Disc set from Toshiba.

An error has occurred.

Please press [OK] to turn off the computer.
I tried erasing the disk, then running the Recovery Wizard again, but wind up in the same place.

It's hard to know exactly what the problem is. You might want to contact customer support because it could just be a faulty disc.

JSP referencinc taglib.tld in JAR file doesn't work.

I have some custom tags which work fine under Weblogic 5.1 when I do a
          normal deployment of files, including the taglib.tld. However, when I
          try to reference the taglib.tld located in a JAR file, then weblogic
          throws an error saying that it cannot resolve into a valid tag library.
          I am only doing this because I am testing the same site agains both
          iPlanet Web Server and Weblogic. iPlanet will only find the taglib.tld
          when it is in a JAR file.
          Can anyone shed some light on referencing the taglib.tld in a JAR file.
          This should work, as it is covered in the JSP 1.1 specification.
          FYI - the jar file is in the same location as the JSP which references
          it. The URI to the JAR file (in the JSP) is from the root of the site.
          Thanks for any help.

Welcome to the Sun forums.
Subject: My Applet Jar file doesn't work !! .
1) Note that one '!' denotes exclamation, whereas 2 or more often denotes a dweeb.
2) Since you are on your first post, I will point out that applets are an advanced topic, and should not be attempted by newbies.
3) "doesn't work" is very vague. It is likely to produce a reply like "maybe the applet is lazy - try flogging it".

i made a jar file :So does the applet work before you make the Jar file? Your post so far suggests the Jar file is the problem.
i created a file and named it MANIFEST.MF .i wrote inside it :
Main-Class: test
Then i placed it in a folder with the test.class .I created jar file using command line.
I entered the test.class path and then wrote this command :
jar cvfm myjar.jar MANIFEST.MF *.class
Then the jar file "myjar.jar" is created .
it's executed but this function "public void actionPerformed(ActionEvent e) " won't wrok.
i keep pressing the buttons but nothing is happening !!So you get 'no output in the console & no effect in the applet'?
What is the URL where I can see your applet failing?
As an aside, since Sun does not guarantee that applet clients will act on the showDocument command, even if it does not work, it would not be a 'bug'.

Are you not seeing the icon of the app you just downloaded (it happens sometimes, and the quick fix is to reset your iPad)? Or are you running out of space on your iPad?

Reading from an excel file

I was wondering, what do i need to look at to get cracking with making a programme that can read from a excel file
I was thinking of making a programme that uses a excel spreadsheet <this spreadsheet is made and provided by the national lottery and has all the winning combinations that have been drawn in past draws> and reading them in and generating a list of combinations that have not occured yet
Its just for a bit of fun, but could be a good challenege
thanks

If all you want to do is select from the excel sheet you may find it easier to use the jdbc option, I have an example of some code I wrote that does a select from an excel sheet and it may be useful for you:Just my opinion here but I would avoid using odbc to deal with the spreadsheet if at all possible.
Time for a war story:
After losing an argument with some business, marketng and management I had to develop a program that accepted spreadsheets as datafiles and it was nothing but trouble.
I experienced all kinds of type problems, the most common and annoying of them being
that the driver (via some logic unknown to me) will determine the type of each column.
Any data that is does not match that expectation is dropped (I found that the query returned NULL).
As far as I could tell there was no way to make the driver treat the data the way you want it too.
After much trouble and lots of manual intervention by the poor person who has to deal with this data on a regular basis it seems to be working but it was not fun it is still very ugly code.
You may not end up reliving my tale of woe, but I though I would give you some fair warning.
As I continue to say "Spreadsheets are not a reasonable data transfer format."
