Representation of images in old and version of Labview
I'm trying to update an old software (working on Labview 5.0 and Windows 95) to Labview 7.0 and Windows XP.
I'm using the NI-IMAQ 3.1 and Vision 7.0.
I've noticed that the new representation of images is a typedef that is a reference to the image object. The old representation seems to be a cluster.
Unfortunately the software which I'm updating makes use of a code interface node which calls a C library. An error occurs, in particular "IMAQ Vision: not an image". I suppose that the C library requires the old representation of image therefore it doesen't accept the new reference.
Before starting to uderstand what the C library does and build a new labview code I would like to know if there is the possibility to convert the new typedef to the old one.
Is anyone able to help me?
Thanks a lot

Hi,
This is Xiaolei.
I also met this problem. Our labview version is 2013, and vision assistant is 2013. The image data type of IMAQ create is refnum, and image data type of camera setting is cluster, so I try use IMAQ image datatype to Image cluster.vi to converter the data type. But it doesn't work since IMAQ image datatype to Image cluster.vi have two elements, but the image in is the cluster of 17 elements. Please find the attachments. Would you please give me some suggestions?
Thank you so much.

Open an old VI version on LabVIEW 8.2
How can I do to open some old VI (made on LabVIEW 6i) at LabVIEW 8.2?
Hi Morim,
Any VI written in LabVIEW 6 or later should convert to 8.5 when you open it. There may be some change in the functionality of the code, I would suggest reading through the 8.5 upgrade manual and going to page 38 where changes in functionality are outlined.
I hope this answers your question.

Image suddenly reverted and history cleared after resuming from screensaver?
Apologies in advance everyone, I'm new here... I checked the FAQs and knowledgebase first, but didn't see anything remotely like this...
I'm running Photoshop CS3 v10.0.1 on Vista SP1, brand-new HP Pavilion m8400f machine w/AMD Phenom 9500 QuadCore 2.2GHz, 3GB RAM, ~600GB free still on HDD, not even old enough to bother defragging yet. I have a nVidia GeForce 8500 GT video card w/256MB dedicated video memory. Driver is updated.
I was working on an image and had to walk away for a bit. While I was gone, it went into screensaver, and when I came back, after logging back in I found that the image I had been working on had reverted back to an earlier state and that the history was cleared. No error messages came up and Photoshop was not frozen, crashed or etc. Business as usual, except that the image was "old," and the history gone.
Luckily it was recoverable, but I'm concerned about this happening again when it isn't. Does anyone have any ideas? I'm fairly sure I didn't click anything by mistake, press a key I shouldn't have...
JessicaAbsolutely, I should have saved. ::smacks forehead:: If I had lost anything unrecoverable, it would have been deserved. My mantra with Windows in general has always been to save early and often... because you never know. Forgot my own advice.
I was just wondering whether anyone else had run into this behavior before. John, I think it was just screensaver, but now I'm wondering whether there isn't something a little odd with the sleep process anyway... it's probably just something weird going on with my computer. Lovely. You buy a new system instead of building one, you hope you don't have to tech things. ::Sigh::
I'm going to be humming that all day at work Dave! Yes it is, it's a magic number...

When I have resized and saved an image in Photoshop (CS, version 8.0 for Mac) using image size, why is it so large when I open it in preview or another image viewer? Has it actually saved according to the size I specified?
You want to view the image at the Print Size, which represents the size that shows in the Image>Resize Dialog.
View>Print Size
Since screen resolution is almost always lower that the print resolution (somewhere between 72 and 96 usually), images will always look bigger on the screen, unless you view them at print size.
(apple Retina displays have a much higher resolution than normal screens, closer to the average print size resolution)

I have an older version of Adobe Digital Editions (around 3 years old) and was very happy with it.
Then I had problems with my Kobo Reader and asked a friend who works in IT to assist. She could not fix the Kobo but she messed up my Addobe. She downloaded version three and I have an account and a password - was not able to transfer my books from my reader to version three (and I don't like the lay-out - I would prefer to stay with the old version as I also loose all my download date info..)
But all the books I have bought over the last three years are in the old Adobe Digital and I cannot access them any more. When I use it I get the message "that the document is licensed to a different account. I can't even open the books on my computer.
When I go to my Kobo library, I cannot also not open my books and get the message "this doc is protected by adobe digital rights management and is not currently authorized for use with your adobe. please sign in with your authorized adobe id and try again"
I believe the problem is that I do not seem to have a digital id for my old adobe or that the Kobo is not in sync with it anymore.
can you please help me - going on vacation in three days and cannot go without books.Please authorize ADE 3 with same credentials that you used with older version of ADE

I can not delete my history and adding new bookmarks.
Upgrading to later Firefox versions and/or re-installing didn't rectify it either.
The address bar still shows the web addresses of old and whenever I make new bookmarks, it's always gone as if it was never made.
Also, I have noticed that every once in awhile you can not close tabs you've opened, either by pushing on the X button and/or clicking on the mouse to close it. Although closing the window and opening it again (without closing the Firefox application) seemed to rectify the problem in the short term, it's becoming quite annoying.
== This happened ==
Every time Firefox opened
== the Firefox is being usedI think I have a solution.
First, download the add-on SQManager. This should be included with FireFox, it is really good.
Look for the file '''moz_hosts''' in the folder '''places.sqlite'''.
Don't delete the file, just delete the information in the file. My file has over 3600 websites, which go back years!! I did not know they were there, but I was frustrated about not being able to get rid of them. They popped up every time I used the address bar. Clearing my history would not get rid of them.
This is where they are stored!! I found that by deleting the pesky web site from '''moz_hosts''', it does not appear in my address bar anymore!!!
I think that if I just delete all the websites in moz_hosts....
Wa-la...History Gone!!!
As long as you don't delete the file, just empty it, FireFox won't know the difference. It will just keep adding websites to it until you empty it again.
Why running "clear recent history" doesn't do this, I don't know. You are doing manually what "clear recent history" is not doing.
Please tell me if you see any flaw in this.

I use an Iphone 4 which had to be replaced recently. However when i did a backup it was on the new IOS version 7, but now that my phone was replaced and i am back on the old IOS version 6 i how do i restore my backup??
When i try to restore my Back up using Itunes this is the message i get - "Unable to restore backup as the software is old - Please setup as a new device and then try to restore your backup" - Please advise. If i do so are there any chances of loosing my data. At this point in time i would be happy if i could just retreive my contacts list. Any suggestions would be greatly appreciated.Nope - you cannot restore a backup from a newer iOS version on to a device running an older iOS version. The reverse works, but in your case to use your backup, you must update to iOS 7.0.3 - no other option if you want to use that backup.

iTunes says that my iPhone is updated, and I've done all the updates, but I've still got an old Bluetooth version and not the new menues. If I download music to iTunes directly that music does not transfer to the iPhone when I sync it to iTunes, but music from the iPhone is copied to iTunes... Any one else who has experienced this and/or have a solution? I'm having big problems with using bluetooth handsfree and I've heard that got better with the new bluetoothversion.
/LindaThank you for your answer, but no, I've got 7 GB free space...

When I have finished working on an image in Photoshop and I hit the "save" button, it goes instead to the "save as" screen. This never happened in previous Photoshop versions. When I get to Lightroom, I have a grey screen the says "File could not be found." I then have to go to "locate" to get the image. When I select the correct image, I get a message that it is not the same file name but I am eventually able to access the image. Needless to say this is having a negative impact on workflow!
The problem with write permissions for the OneDrive folder only shows up in Lightroom 6's export dialogue, that's why it's to irritating. Lightroom 5.7.1 is not having that problem nor does the file explorer. The problem also exists on both of my machines. I will try to check for other problems with the OneDrive troubleshooter though: Running the OneDrive troubleshooter - Windows Help

just got a Nikon D610 and CS5 for Mac can't open the images -- message says installed version of camera raw doesn't support the camera. Downloaded the Raw 6.2 update for Mac, but installation failed. Now what?
The D610 didn't get out-of-the-box RAW support until Photoshop CC.
You can either upgrade to CC or use the DNG Converter to convert and open your DNGs in CS5. -
I created an image in Photoshop and saved it as the PSD file. Now when I try and open it it says it is not compatible with my version. How could this be when I created it in this version?
That depends on why it won't open. Most of the time it means the file is corrupted and unlikely to be recovered. If you saved it right after adding or copying a LOT of layers - then it might just be the layer limit and we can attempt to recover it.

Glenn,
I tried upgrading to leopard, even bought the software and brought it home but it wouldn't let me. So i went back to apple, gave them the specifications of the machine and been told my machine is simply too old for leopard. This is incredible to me because it really isn't THAT old (i think just a little over 6 years maybe) and yet i'm left out on the curb when it comes to using newer apple products. I understand technology moves on but the mindset that i am supposed to dump a perfectly working machine after a couple of years or face not being able to use any other apple product is counter to what thought apple was about. -
I've tried the new iWork (on a friend's new MacBook Pro) and feel very disappointed. I'm gonna stick with my old '09 version. It appears to have lost utility, and is now easily surpassed by Word 07. Dear Apple, from a veteran user: In your rush to market, you have dropped the basket on this one! Is a new version that's worth the money and hype coming?
Welcome to Apple Support Communities
A lot of users have complained about the lack of features of the new iWork version. However, I'm sure Apple will add features with more updates in the future, like with Final Cut Pro X. See > http://support.apple.com/kb/HT6049?viewlocale=en_US&locale=en_US
Until then, you can carry on using iWork '09, or try Microsoft Office 2011 or even LibreOffice, which is free and open-source -
My MacBook was wiped of all my music and everything else, and now my iTouch is the only device with my entire music database. My iTouch is old. (Version 6.1.6, Model number: MC547LL/A) Is there any way I can put all the music on my iTouch back onto my MacBook? I hate that I could lose my entire music library by dropping my iTouch in the toilet.
I've tried to plug in my iTouch into my MacBook, but I can't seem to give the music-transfusion without subscribing to iTunes Match or just completely wiping my iTouch.
PLEASE HELP MEEEEEYour i-device was not designed for unique storage of your media. It is not a backup device and media transfer was planned with you maintaining a master copy of your media on a computer which is itself independently backed up against loss. To use a device with a different setup you transfer the old library from a computer or a backup directly to the new setup, not the device to the library. Media syncing is one way, computer to device, updating the device content to the content on the computer, not updating or restoring content on a computer. The exception is iTunes Store purchases which can be transferred to a computer.
iTunes Store: Transferring purchases from your iOS device or iPod to a computer - http://support.apple.com/kb/HT1848 - only purchases from iTunes Store
For transferring other items from an i-device to a computer you will have to use third party commercial software. See this document by turingtest2: Recovering your iTunes library from your iPod or iOS device - https://discussions.apple.com/docs/DOC-3991

Having problems finding and importing actions I recorded in CS5 :(
Hi. I've recently upgraded from CS5 to CC but I'm now having problems finding and importing actions that I previously had recorded in CS5. Where do I need to look to locate these actions, as they are still in CS5 when I open it.
