Reading QR code
Heno... recently I'm using the example labview, QR to read code.vi... I discovered something odd when I rotate the image 45 degrees and turn it to the position of origin... the vi on an error message, that:
But this image may initially be decoded by this vi... the strange thing is that after the rotation, even turn to the original position... it does not make the decoding process... do can someone know what is happening here?
This is the image I used to decode...
The error introduced by labview occur usually when you try to do an operation on a type of image is not suitable for the operation.
types of images are:
RGB 32
RGB 64
U8
I8
U16
I16
etc...
and refers to the type of data used for a pixel
When you turn usually provide a destination image, and my guess is that the image of the dst is a different type of what is gone...
the output of rotation is now DST type, rather than the type of image input.
to avoid this, when you create the image of the dst, use the 'get image info' to get the type of the input image, then the wire that the image 'create '.

Hello
I joined a program to read the QR code. This program can read QR codes I generates on the web for example (see attached 'QR code'), but I can't read the QR code of an image (see Test_snap_jpg). This photo is engaged with a mini USB camera. The photo is a little blurred, but that shouldn't be a problem to read the QR code. I tried to read directly from the screen with an iPhone app QR reader and it reads perfectly. The problem is probably related to the shape or the size of the image, but I can't understand. What to do. Someone has an idea?
BR,

Your test_snap_jpg.jpg file seems to be corrupted some how.
I downloaded and tried to open it with LabVIEW, but he reported an error. Your Code.jpg QR original opens in fine LabVIEW.
I tested your images against the decoder online zxing
http://ZXing.org/w/decode.JSPX
Your image of component snap-in has not been recognized, your original QR code file decoded successfully. I did open your component file snap with SnagIt, save it as a png and open it with LabVIEW. I could see, but not decode it.
I presented the convert png to the decoder zxing online, he could not detect the bar code in the image.
The problem seems to be in your image file. Not sure where comes bands in the image.

How to read bar codes using qith and the mink of Gige camera software
Hello
I have a Gige vision camera, I need to use it to read bar code and save it in a file. Is there a way to read a code bar directly from the camera with LabVIEW to mink. Please let me know if there is a way.
Thank you

Hello AnkitG,
If you open the finder example in Labview, there are examples of code bars. They are under the Modules and Toolkits > Vision > Applications. You should find two examples of how read bar codes.

Check read the code 0000 T500 failed error even with a new hard drive
Hello
My T500 was slammed very hard one day, once I reboot, he worked for half an hour and gave up. I tested via the BIOS, he gave me code 0000 read failed error check.
I presume that the HD is dead, inserted an a healthy Interior and works very well for a few hours and give up once again, tested by BIOS gave me the same error code.
I was wondering what problem could be?
best,

You can also prove that it is a SATA interface error by testing two hard drives in a box USB or Firewire. If you can live without portability, then perhaps this is also an option to use the T500 in the future.

I'm looking for a website design Web e-business that helps clients create an account on my site. must be a drag and drop, Web site editing. WiX and weekly cannot meet this need. pouvez muse? also, I read the reviews that muse product causing a 'bad code' not if good integration on some devices, browser e.t.c. Web site has this changed, improved? I really want to be able to design my own e-business very graphic design friendly way... I can't code, nor have I not the energy or the time to learn to (don't really want to..)
If anyone knows s if theres a way to do this in a wix or weebly, I'd appreciate knowing because that would allow me to save a lot of time. Oh I have no money to associate a Web Designer...
Oh, this isn't only ease of connection member... its an installation account roughly as installation located on topman, River Island and other sites detailing.
AppreciaitonsThis has nothing to do with the Muse. Management of the user accounts, payments and what you have is linked to a backend suitable running on a server by using electronic commerce systems such as XtCommerce and CMS such as Joomla, Typo 3 and so on. Of course, you can sign up for an additional account Business Catalyst Pro as well. Whatever it is, you are nbot getting away with a free meal. It costs a monthly fee in the world.

- Thanks his old but nice machine
Hello
You have received incorrect information from Blue microwave
"I have a new Toshiba with 7"
You cannot move the key product/license OEM Windows 7 preinstalled on Toshiba computer to another machine.
Here is some information on the license OEM Windows 7 has been preinstalled on your new machine from Toshiba
If the laptop came with the preinstalled Windows operating system (Dell, Toshiba, HP, Acer, etc.), it is an OEM license and this product key supplied with the laptop is preinstalled OEM license and is not transferable.
Preinstalled OEM license of operating system on Toshiba, Dell, HP, machinery etc. is related to the first machine that it has been installed on and dies when dies of this machine.
Only retail OS licenses, you buy and install yourself, are allowed to transfer to another machine.
OEM licensing rules:

Follow the advice of Mike Hall MVP and go back to XP.
See you soon.

another message comes up and says "Insufficient for an image" and the page

Any help would be greatly appreciated.

A "quick" fix that worked for me was to uninstall Adobe... and download Adobe Reader 11.0 installation base.
Then download each individual updates and run them sequentially.
I installed back to the last update of security which is version 08 and were able to register under normal operations.
You will need to disable the automatic updates to keep up with the 08 version, until Adobe fixes this problem in a future release.
