The vi is identifyng the number of bytes to be read but the VISA Read vi is not able to read the data from the port.

We are trying to communicate with the AT106 balance of Mettler Toledo.The VI is attached.
We are sending in "SI" which is a standard command that is recoginsed by the balance. The balance reads it.The indicator after the property node indicates that there are 8 bytes available on the serial port. However, the VISA read VI fails to read the bytes at the serial port and gives the following error:
Error -1073807253 occurred at VISA Read in visa test.vi
Possible reason(s):
VISA: (Hex 0xBFFF006B) A framing error occurred during transfer.
The Vi is atttached.
Thanks
Vivek

Hello,
You should also definitely check the baud rates specified; a framing error often occurs when different baud rates are specified, as the UARTs will be attempting to transmit and receive at different rates, causing the receiving end to either miss bits in a given frame, or sample bits more than once (depending on whether the receiving rate is lower or higher respectively). You should be able to check the baud rate used by your balance in the user manual, and match it in your VI with the baud rate parameter of the VISA Configure Serial Port VI.

What is the 'quickest' way to read char data from a txt file

Hello,
What is the 'quickest' way to read character data from a txt file stored on the phone to be displayed into the screen?
Regards

To be even a bit more constructive...
Since J2me does not have a BufferedInputStream, it will help to implement it yourself. It's much faster since you read large blocks at ones in stread of seperate chars.
something line this lets you read lines very fast:
while ( bytesread < filesize ) {
         length = configfile.read( buff, 0, buff.length );
         // append buffer to temp String
         if ( length < buff.length ) {
            byte[] buf = new byte[length];
            System.arraycopy( buff, 0, buf, 0, length );
            tmp.append( new String( buf ) );
         } else {
            tmp.append( new String( buff ) );
         // look in tmp string for \r\n
         idx1 = tmp.toString().indexOf( "\r\n" );
         while ( idx1 >= 0 ) {
            //if found, split into line and rest of tmp
            line = tmp.toString().substring( 0, idx1 );
         /// ... do with it whatever you want ... ////
            tmp = new StringBuffer( tmp.toString().substring( idx1 + 2 ) );
            idx1 = tmp.toString().indexOf( "\r\n" );
         bytesread += length;
      }

Hi
Also, check where the window is placed in the Form Painter...may be it is not on the page properly..and also check the size of the window..
Further, check the paragraph format that is used.

I can't synch my iPhone with iTunes because the device does not show up in a device window when I plug it in...it's missing in action and thus I'm not able to add any content from the iTunes to my iPhone, e.g. podcasts

I can't synch my iPhone with iTunes because the device does not show up in a device window when I plug it in...it's missing in action and thus I'm not able to add any content from the iTunes to my iPhone, e.g. podcasts. All the instructions on synching start with "find your device in the device window". But what if you have no device window?

Missing "message" from above: The iPad "DGMTR" is synced with another iTunes library on DGMTR's MacBook Pro. Do you want to erase this iPad and sync with this iTunes library? An iPad can be synched with only one iTunes library at a time. Erasing and syncing replaces the contents of this iTunes library.
I thought the libraries were the same.

I have a Iphone 4, upgraded to ios 5 with itunes 10.5 Since doing upgarde to both Itunes and Iphone I am not able to add individual songs from my itunes library to my Iphone. I get a grey listing of the song and the sync symbo but it is not moving.

Paul--you are a life-saver!! Worked great. I did have to look around to make sure I was getting 4.9 instead of 4.7 (even when the file was named 4.9 at techspot.com), but I finally got the right file, did the install as you suggested, and everything is now fine. One note, though, that I haven't seen mentioned in any of this thread: when I first tried to open up iTunes after getting back to 4.9, the following message appeared: "The file iTunes Library.itl cannot be read because it was created by a newer version of iTunes." I merely went to the old .itl file that was created when I did the update to iTunes 5, renamed it, moved it over to my now new 4.9, and iTunes opened fine. My library was a few days out of date, because of the few days' lag from the time I did the iTunes update, but that was easily taken care of, and everything's now working fine. Thanks again!!!

I've been using LR with my Nikon D3200 for a year or so. Shooting in RAW/NEF no issues with import etc until I updated LR and now I can't get LR to allow me to select when I try to import. It does show the images but they're grayed out and not able to be selected. Any thoughts? TIA

Greyed imaged in the Import dialog box mean you have already imported the photos into Lightroom, so there is no need and no benefit to importing them a second time.
Just go to the Library module, search for the desired photos, and resume working on these photos.

If you have a rescue email address (which is not the same thing as an alternate email address) set up on your account then the steps half-way down this page should let you reset them : http://support.apple.com/kb/HT5312
If you don't have a rescue email address (you won't be able to add one until you can answer 2 of your questions) then you will need to contact iTunes Support / Apple to get the questions reset.
Contacting Apple about account security : http://support.apple.com/kb/HT5699
When they've been reset (and if you don't already have a rescue email address) you can then use the steps half-way down the HT5312 link above to add a rescue email address for potential future use

Not able to update any apps from new apple id.. Old id im not using anymore., cannot access the old one

Not able to update any apps from new apple id.. Old id im not using anymore., cannot access the old one.. But during update time asking for same old password of old apple id

If you change your Apple ID, all the apps you purchased with the previous ID will no longer updatable for you and this problem will continue. You see your old Apple ID because you are likely still using some of the apps purchased on that ID.

I paid early termination fee two months ago to Verizon and am now out of the country. Am trying to unlock the phone but the local guys say they are not able to. I see from the blog here that iPhone 5 comes unlocked. Is it true?? Do I still have to unlock.

Thank you for reaching out to us, Texasman. Sad to see that
you have left the VZW family, but it is definitely awesome to be able to
travel! Regarding your iPhone 5, the phone is unlocked for international usage.
Just need an active local SIM card that is compatible with your iPhone. Your local provider
may need to configure some settings under Cellular, but it should pick up signal. Just in
case, make sure that Settings>Cellular>Roaming>Voice & Data are
active.
