Open file in main vi, write in subvi and close in mainvi
Hi,
Im opening a file in the main vi , passing the reference number to the
write to text file which is located in the subvi and passing the refnum
out from this vi to the main vi again to close the file.
But, I always have only the last value of the measurement stored.
Im getting data from the serial port.
what am I doing wrong?
Can someone help me.
Thanks and regards.
You probably have forgotten to set the "Write" function to APPEND the data to the file.
This has nothing to do with where you are writing the file. Check the inputs for the write function and make sure you set it up to append.

I have recently updated the new apps via creative cloud now photoshop and bridge no longer work, they open then say they have encountered a problem and close, I also tried opening the old version of photo shop but getting the same result
What OS version? What's the exact error? Exactly when does the error occur? What previous versions? What is on the screen when the error displays? Does Photoshop get fully open?
Try opening Photoshop holding down Shift key immediately to turn off plug-ins. Lots of good suggestions here: Photoshop: Basic Troubleshooting steps to fix most issues -

Untitled Project 1.lvproj 7 KBI'm not sure which version of LabVIEW you are using, nor what some of the VIs are in your code. However, if you have a recent version of LabVIEW (say 2012 or later) and have access to the Report Generation Toolkit, you will have a much easier time working with Excel.
In January of this year, I posted an Example to replace the Excel example that ships with LabVIEW. However, I'm not very good at finding my own posts on this forum, so I can't easily point you to it. However, if you do use the Report Generation Toolkit and do not use ActiveX calls, you will find that the functions to open and close Excel Reports tend to work without significant problems (there is a glitch, that I've reported, whereby if you "manually" close the Excel Workbook and then try to close it with the Report Generation's "Save Workbook", it will actually delete the manually-saved Workbook for you)(there is a "work-around" until NI fixes this ...).

This was happening with FF 3 before upgrading to 4, and was not happening with FF4.0 until the 4.0.1 update was applied, the first time it ran. Same issue on another computer running FF3, so may be a extension related problem.
If I have three windows open and close the third, I do Not get this. Only when two are opened and one is closed. I could have three, close one, then the second and get the prompt.

Why do CS4 always open files on main monitor ???
in the older versions, photoshop opens all the files on the monitor on which the last time pictures were closed. in cs4 this does not work, alwasy opens the pics on the main monitor. so i have to drag every picture from the main to my "picture calibrated" second monitor.
can i fix this problem anyhow???>didn´t wanna know anything about the workspaces.

Sack:
If you typed in standard English (" I didn't want to know ), it might be easier to understand you.
I made a suggestion which might work to solve your problem with your monitors but if you are to idle to even try it, you will have to solve this for yourself.
Or you could telephone Adobe Tech. Support. -
Opening file in Illustrator prompts "Text Import Options" and does not open file correctly.
I've been dealing with this issue for quite a while and I am thoroughly stumped. A co-worker has emailed me .ai files in the past without issue. In the last couple months, however, her attached .ai files no longer open properly.
This is the first screen I get when trying to open the files:
Regardless of what checkboxes are marked or options changed, the outcome is always the same:
If you can't read that, the error code is as follows:
{"Body":{"ErrorCode":500,"FaultMessage":"Unable to get write stream for mac attachment.","IsTransient":false}}
Putting this line of code into Google returns exactly "0" finds.
Nobody else in the company seems to have an issue with opening the same file when this co-worker forwards it to them. I did notice, however, that the file is 141 kb within her email, but when I download it, it shrinks to 344 bytes. I don't know if for whatever reason my computer is just not downloading all of the information or what might be going on.
To reiterate, these are the facts that I know:
1. She is on a mac and I am on a PC.
2. We are both using Illustrator CS6.
3. Other co-workers on PCs do not have this problem when she emails it to them.
4. The file shrinks from 141 kb to 344 bytes when I try to download it from her email.
Edit: I just had her send the email to my personal gmail account and the file opened perfectly, so this appears to be an issue with office365.com which is where my business email is located. Everyone else here uses the same email service, however, so this is still an isolated issue with my account.
Any help or ideas would be very much appreciated.
Thank you!Thank you for the reply. We went through a lot of different ideas to try and fix this, but zipping the file never even crossed our minds for some reason... :\

I seem to randomly get this error. I am running a rather complicated 'for' loop that runs about 1000 times. I get the following error somewhat sporatically. I think this has something to do with a file permission error, but I cannot find a way to fix this error, not can I make it consistently occur at the same time.
Any help?
Thanks a ton.Most probably another application (e.g. disk indexing, antivirus scan, backup, etc) opens the file and denies your application write access for a short time.
You can ignore this error retry since it for a short time. Another solution is to set the deny mode to "deny read/write" when you open the file. That is a setting on the "Open File" node. By default, LabVIEW opens file allowing simultaneous read/write access by other application. This is seldom required and wouldn't be a problem if the other application didn't lock the file for itselt the time it access it. Unfortunately, the high level File I/O VIs don't allow to set the deny mode on the file; you have to open the file using the "Open File" node directly.

I have a very important document and it is saved only o the icloud (which I thought would be fine). Only now, whenever I try to open it it gives me the message 'can't open file'. I'm a PhD student, and that file represents a lot of work for me. I did it on the ipad because I had to travel, and now I'm kicking myself. I need that file! Is there any way to get it back?
Thanks for your suggestion - I have tried that like 50 times (I was feeling the desperation and thought if I reset enough times it would do it), and I have also tried turning off and on the cloud, adding .pages to the filenames, downloading (didn't work) emailing to myself (did work, wouldn't open). When I looked at the package contents of the file, it did not have a file for content in it - or not one I can find. I'm afraid that it's lost the content within the file (though I don't now how it could!).
I've not had any joy with anything else I have read online. I think it's a more knotty problem than a simple off/on again job! -
When I open the "open file" dialog box using the ctrl+O and then hit the escape key to exit the box, I get an error message which I'm not able to paste here.
it says something about a runtime problem and if I try the same thing again to reproduce the problem, it will sometimes just hang and windows vista will tell me the program is not responding.
I've checked to see if there are any crash IDs but none were found for this time frame.
I have even disabled all add ons.
I'm currently using vista 64 bit edition and Firefox 6, beta edition.Hi,
Please also try right-clicking on the link corresponding to the language version and '''Save Target As''' to save the Firefox installer. If the problem persists, posting [http://answers.microsoft.com/ here] would also be helpful.

IWeb will not start, menu items dim, cannot open files
I designed a website using iWeb and need to make modifications to it. However, after I tried to open an html file with iWeb and get this message:
"Can’t open file “~/Sites/qhuyn002/Howto.html”
...iWeb closes on me. While this message is up and before I click OK to make it go away, the menu items are dim, and I cannot access any websites I've designed and saved in my "SITES" folder on this Macbook.
I've re-started the computer many times. Same issue keeps coming up. iWeb seems to think that every time I open it, I am trying to open this html file. I just need it to start as normal so that I can use it!
HELP!Up until V 2.0.3, iWeb stored the domain file for the last site that was opened in iWeb in Home Folder/Library/Application Support/iWeb.
After I updated to V 2.0.4, I discovered that there was no domain file there. I keep all my domain files in separate folders in an "iWeb" folder kept in a second dock using Dock-It so that I can launch any site with two mouse clicks.
Just for fun, I launched iWeb from the application and a site that I had "lost" during the upgrade appeared. It is still there and doesn't change no matter what site I launch in iWeb!
Some people "lost" their domain file after the upgrade and couldn't find it on their hard drive although it would still launch in iWeb. It wasn't in the default location.
I didn't report this to the iWeb development team as it didn't cause me any problems. Has anybody done this?
Most problems with upgrades to iLife and iWork applications occur because, if they are not instructed to do so, some people don't bother to do a restart after installing them. -
