• Vista Service Pack 1 installs - perpetual loop

  Hello! I was wondering if anyone would be good enough to help me. I'll have the perpetual loop of Service Pack 1 by saying it is installed but is not as he continues to repeat in Windows Update. I made a new reformat and reinstall yesterday to solve the problem, but is happening all over again. I ran the tool Vista only strengthened. I just ran a FixIt and he could not solve the problem of Windows Update. I'm worried about the stability of my laptop. I'm not wonder with computers. It's a Toshiba Satellite A210 Vista 32 bit Home Premium btw. I ran the Windows 7 Upgrade Advisor to see if I could just get the hell outta Vistaland altogether and go to 7, but I need that SP1 installed even for that! Having a nightmare. Help, please. Thank you, Simon :)

• Configuration of updates - in perpetual loop

  Hi, I am trying to turn on my laptop, but keeps it shut itself down and restart with the message: "Configuration of updates. "3 of 3 0% complete"
  Then it stops again and goes back to this message.

  I'm desperate to get a file on my laptop, but this does not stop the case. How the hell do I? Any help is GREATLY received!

  Thank you very much

  You can start your laptop in safe mode (F8 at startup > safe mode)?

• Update configuration 3 of 3 loop

  Configuration of update: stage 3 of 3% full. Do not turn off your computer.  Can't get out of this loop. Tried all that the security modes, but they come back to the loop. Tried to fix your computer, also without help. Didn't back up the disk to restart.  Any help?

  Hello

  1. How were you running Startup Repair?

  2. do you have the installation media to perform the computer repair?

  3. What is the brand and model of the computer?

  4. what happens when you try to start in safe mode or other tasks? Do you have an error message?

  5. were there any changes (hardware or software) to the computer before the show?

• Tried to update in Windows Vista Home Premium, stuck in the "Configuring updates" and "reboot" loop 11/05/2011

  Hello! I have a portable M-6752 Gateway under Vista Home Premium.  It was perfectly functional this morning 11/05/2011.  Then I noticed the sign (of exclamation in a circle) who said the new updates.  So I started the update and thought nothing of it.  It was until an hour later and I realize that my laptop was still updated.

  Right now I am stuck in a loop between "Configuring updates: stage 3 of 3-0% complete.»  Do not turn off your computer' and auto restart.
  I tried to restart in 'safe mode' and 'safe mode with network.  These attempts did not help.  I'm still stuck in the loop and my laptop is overheating.  The only thing I could do was to be able to.  Fact that several times already.
  Fortunately, I have another laptop and is able to ask for help.  Can someone help me?  I'm NOT a technical person.  Thank you.

  Thank you, but my laptop WAS running Service Pack 2 when this problem happened.  It has been resolved.  For anyone having this problem, here is my experience and solution.

  When I found myself stuck in a loop and my laptop keeps restarting without giving an error message, it began to overheat.  I turned off.  When I turned on it again the screen "Advanced Boot Options" appeared.  I chose 'Safe Mode'.  Then, I went to "Configuring updates...". ».  Machine started himself reboot again.  It happened a few times.  Finally I had to turn the phone off again.  All of a sudden when I turned on again, the "Windows Error Recovery" screen comes on.  There is a choice, 'Launch Startup Repair'.  I chose this.  Machine asked me if it is allowed to create restore point.  Of course.  Then I GOT!  I was saved by Windows self-diagnosis program.
  If you are not familiar with the screens that I mentioned, please search 'screen name' and the word 'image' as a whole.  You will see what these screens look like.
  Now I realize there is another way to reach the Startup Repair.  When you turn on again, press the F8 key several times.  Which will bring you to the early Startup Options screen.  On advance Boot Options, there is a choice 'repair your computer', scroll down to this choice, press ENTER.
  Turning off my machine during the restart is another way to force the "early start Options" screen appears.
  I read that some do not have the "Repair your computer" option according to your PC in the screen «In advance Startup Options»  You will need to know how to get to the "Windows Error Recovery" screen.
  As a last resort, you can restart Vista recovery disk.  Many manufacturers do not understand that when they send the PC for you.  However, it is available for download for free on the internet.  You can download and make your own within 30 minutes.  I hope this helps!

• The configuration of Windows Update loop again and again and again...

  While on my computer, I received a pop-up to restart my computer for Windows updates.  I fact and 2 of the 3 downloaded.  For the 3rd, my computer restarts, the vista logo appears and the screen is blue saying 'configuration update 3 of 3 0% complete'.  The problem is it never moves 0, constantly restarts itself and has been done for more than a week (I can't leave my computer on all day).  I'm frustrated and want to come back on my computer, but no matter what I do (restart it, put it in safe mode...) it won't go past the updates configuration message.  What should I do to fix my computer and have it show the office, etc. ?

  Hello

  To see the version of Windows - Start - type in the search box-> Winver find at the top of the list and double-click it.

  (Or for XP Start - Run - type Winver hit)

  I guess that part of the question could be a driver which is really old or similar should not be loaded.

  This exit Windows updates on (after you have access) and stop the updates of the driver to load.

• Post in "infinite loop" starting from El Capitan migration

  Hi all

  After an easy migration of Yosemite to El Capitan 10.11.4 for my MacPro (end of 2013), surprises: at startup, Mail display 2 superimposed dialogues that perpetually loop at about 1 second period preventing any other action with the Finder. The more 'readable' dialog box is titled: 'upgrade of the current library', the second last less time and I can just read the beginning of the title: "Migration...." ». I waited more than 24 hours in case it has been a very long process, but... Santa came

  I have a little video, but apparently, it cannot directly attached to this message...

  Here's a link: https://youtu.be/hmR32wn4ejE

  Yesterday, I thought I found a solution: after removing "Maildata" from its location, Mail folder loaded normally and gave an update of my ISP (POP and IMAP) accounts. Everything was normal (somewhat long) and I tested sending and receeiving for several mailboxes without encountering any problem... After 2 hours of racing, I quit Mail and re-load: disaster! Starting the State returned with the "recycling of dialog boxes"...

  I suppose that a resource is corrupt but have yet to find that one...

  Thanks in advance for your help

  One of 2 dialog boxes...

  

  The new version of Mail stores its database in a different format that the old, so the database must be converted before Mail can use it. Sometimes, the conversion fails because the old database is damaged, or because of a bug in the conversion code.

  What you should do depends on what type of e-mail accounts you have. The first step, no matter what you do, is to save all the data, if you don't have a current backup.

  Please read this post in full before anything else. If this is unclear, ask for clarification before taking a step. If you're not convinced that you can follow instructions, stop, don't change anything.

  A. Si you know that you have IMAP or Exchange only e-mail accounts

  The easy way to recover is to delete the old database and start over. You can do this without losing all the messages, provided that:

  ☞ All your incoming mail accounts are on an IMAP or Exchange Server

  ☞ You store messages sent on the server

  ☞ You have no mailboxes "on my Mac".

  Independent mail services the best-known as iCloud and Gmail are inspired by the IMAP. On the other hand, hosted by ISP e-mail services often use pop. If your ISP is one of your providers of mail services (or the only), you cannot use this procedure. See below part B in this case.

  If the above conditions are met, please continue to do so.

  Quit Mail runs.

  Open your home folder's library folder by pressing the option key and selection

  Go ▹ library

  in the Finder menu bar. Inside, it is a subfolder named "mail". Move this folder on the desktop. You do not move the e-mail application; you move a folder named "mail".

  Launch of Mail. The mailboxes must be restored automatically. The messages will be downloaded from the servers, so it can take a long time if you have very large mailboxes. Some people have mailboxes in the gigabyte range, and which can be a problem if the bandwidth is measured or the Internet connection is slow.

  If the mailboxes are restored successfully, you can delete the folder that you moved to the desktop. You may have to re-create your rules, signatures and custom stationery Mail. If it's important for you not to have to do these things, ask for instructions before you delete the folder.

  B. Si you have a POP or "on my Mac" mailbox store, or if you don't know what you have

  Move the folder of mail on the desktop as in the part has and open.

  Press the key combination command + F to search. In the line of chips to search along the upper part of the window, select "Mail". Below, defined as the search criteria

  The name ends with mbox

  Results of the research will be a list of folders with a name ending with '.mbox '. Each of them represents a box the letters.

  Launch of Mail. All mailboxes will be empty at the beginning, but if you have any IMAP or Exchange mailbox (including iCloud), they should fill in automatically after a delay, as in part A. If you have now all the messages you want to keep, you can stop here. Otherwise, import from mailboxes in the search results. The article of support related, select

  Apple Mail

  as import format. You'll probably want to jump boxes to letters with names such as "Deleted Messages", "Junk", "Spam", or "Trash". Some may be duplicates of what you already; those that you can remove.

  In some cases, a mailbox may fail with an error to import. If this happens, thanks for posting your results.

  If all the mailboxes that you want to import do successfully, you can delete the mail on the desktop folder.

  I'll insert a text that I found somewhere else... I still can't get the Dell PC to start. Here is the text.  I think that this problem is an old man, and I'm not sure what to do next.  This is just an excerpt from a very long list of events.

• HP Pavilion e020us 17: 10 Windows will not start

  I worked on a portable computer that no longer starts.   If I boot from the hard disk in the recovery partition I can't start there on the Windows partition.  I have a choice of Windows 10 of Volume 4, Windows 10 of Volume 4 (Yes it is listed twice) and the Windows recovery environment.  Picking either 10 Windows starts the computer in a reboot loop that can only be stopped by pressing ESC and returning to the recovery environment.

  Boot from CD and try to repair the operating system does nothing - he says that he cannot repair the computer and goes to the recovery environment.

  Auto repair, recovery Image system and System Restore does not work.

  Command prompt shows everything on the C drive is still in place.  CHKDSK shows that all is well with the drive.  But I can't boot from the drive.

  I have not tried to reset the computer only because I'm going to do as a last resort.

  Any suggestions on what to do next?

• myRIO sampling rate

  I'm new to myRIO and use it to measure sine wave (0V to 5V) of up to 10 Hz 20 KHz. I also quickly transformed of Fourier (FFT) of the signal measured in real time.

  Sideways FPGA of things, I try to keep things pretty simple, just read 2 channels of AI (connector B: AI0 and AI1), therefore potentially able to read each HAVE 250 kech. / s (as the unit has a capacity of 500kS/s). Does that mean this program gets a two analog inputs data exactly every 4 microsecond? If this is not the case, how can I make sure that the data is acquired through a fixed sampling rate?

  

  I realized that we can add to the FFT in FPGA function, but I wanted to manipulte the acquired data of analog inputs before it is sent to the FFT, which I don't know how to do now. Can someone explain me how do the arithmetic data (muliplication, division and so) on the acquired data and analog inputs to reducde the 12-bit resolution 10-bit to program FPGAS.

  Later, I created a myRIO program to read analog data 2 FPGA program which continues to turn in timed loop. In the program myRIO, the timed loop is configured to 1 MHz clock source type by a delay of 25 microseconds.

  This configuration means that the loop runs exactly every 25 microsecond?

  When I set up the less than 10 micro second time, myRIO has stopped working. Why is it so?

  Is it because myRIO cannot run as fast as FPGA?

  

  It is advisable to make the FFT of myRIO side analog data or FPGA?

  When I tried to do FFT using the power spectrum of myRIO side, he asked for waveform data. What I acquire is data analog. How can I convert in waveform data?

  If I read in the forum for help, I couldn't have the full answer to my doubts

  Discussions at the Forum I did reference:

  A lot of good questions here, I will try to answer as much as I can so as to offer a bit of advice.

  First of all, if you are looking to acquire data at a very specific rate on the FPGA, you'll want to use the Timer VI.  You are also going to use a FIFO of DMA to transfer data of FPGA in real time. A node read-write using as you do now means you'll run out of samples, or read the sample even several times.  The link below is a very good tutorial on how to do what I described above.

  When I set up the less than 10 micro second time, myRIO has stopped working. Why is it so?

  In general, you should not run a timed loop much faster than 1 kHz.  Using timed inside loop knots, you can monitor the real rate of loop during execution to see if f you meet your needs of the moment.

  The portion of your myRIO RT is slower than an FPGA in the sense where it cannot manage the rates of lines 40 MHz (he makes up for it by being able to work with much better pictures) and it is important to remember that it is just a computer.  The advantage of a real-time operating system, is that you have more control on the Scheduler, not that he is faster (less jitter, not faster code). There is more good reading below.

  It is advisable to make the FFT of myRIO side analog data or FPGA?

  When I tried to do FFT using the power spectrum of myRIO side, he asked for waveform data. What I acquire is data analog. How can I convert in waveform data?

  I would say that it is generally advisable to treat your FFT on the side FPGA as long as you have the resources available, but for many applications probably little matter ultimately.

• niUSRP automatic tuner FM 2920

  Hello

  I'm improvising on NOR condition example of FM demodulation, in which I try to create auto tuning feature and store FM channels available in [0-9] table 1 d to 10 preset stations. What I need to design my own driver, as I am not able to niUSRP driver configuration Rx in a loop. The errors I get States that the Configuration niUSRP driver should be initialized and not running.

  Any ideas how I might be able to sweep of 88.1 MHz to 108 MHz and store 10 stations? I have not received the permission to share my .vi, so I am limited to descriptions only.

  Thank you

  Use the node property for frequency LO and the carrier. There is an example of navigation that uses these functions.

• Trigger by using PCI-6233

  What is the best way to trigger an entry to start of data acquisition when the test unit is in analog motion?  I use a card of acquisition data PCI-6233.  The input voltage is generated by a linear transducer.

  Thank you

  Gerry-

  Your card doesn't support a trigger analog input.  Your card must support a digital signal of 10 VDC, but if you are worried the voltage is high so that it triggers, then you can use a voltage divider to reduce the strain of your relaxation.  You could try to get edge in case your switch is wired backwards.

  If the signal you are measuring is a floating source and you use differential measurement, hold on to the positive terminal to your terminal block 1 Terminal and the negative terminal to Terminal 2 and use a wire between terminals 2 and 3.  It is the best way to measure a floating source.

  If the signal is floating and you're not really worried about the introduction of ground loops, you could plug it as unique reference ended.  That is the positive wire going to Terminal 1 and the negative terminal goes on Terminal 3.

  You will use these same configurations if the source is grounded.  Again, differential is the best configuration to avoid Earth loops.

  For your relaxation, you relate to the positive terminal of the source of 10 VDC to Terminal 13 and the negative terminal of the Terminal 14.

  I hope this helps!

  Thank you

• Visa erroneous zero byte in reading series

  Hi all

  Trying to debug a problem that I have with a Labview2011 VI and the USB-485/2 device.

  The installer has been simplified to get the wire from port 1 to port 2 in a 2wire-auto configuration. As described here:
  http://digital.NI.com/public.nsf/allkb/D5CC369B3E3E6F0586256D1600563245

  and here:
  https://decibel.NI.com/content/docs/doc-4169

  Port 1 sends a message of 8 bytes by using visa / writing then begins a visa-reading of 8 bytes. (timed content in a loop of 10 Hz)

  Port 2 is configured in a single loop using the wait for event visa byte, then visa-read 8 bytes, connected directly to visa / entry.

  For 1 Port data transmitted, the data received and read visa error code are recorded on the disc.

  The success of installation passes are receives data without loss... so the back loop work...

  However! Occasionally, another zero byte is read from visa-reading the port1.

  Almost all the code read visa back operations "1073676294" port 1 (the number of bytes transferred is equal to the number of entries requested. More data may be available) which is very good. Even if sometimes the error code '0' is back (operation completed successfully). This "0" code seems to be associated with the extra byte in the receiver.

  This causes a problem because it throws the mismatch scheduled application command/response pairs.

  I tried many tariffs buad, visa-read timeouts and transmit frequencies, the problem remains. Adding a visa-flush buffer prevents the error from reproducing, but won't stop him intervened and upsetting the logic of command/response.

  Any ideas would be appreciated.

  If you send real binary data (which it looks like you are), you should have the off stop character.  Remember that reading VISA will be completed when the FIRST of the following: the desired number of characters is read, the character of endpoint found, there is a timeout.  So if there's a 0xA in your data, which will stop the read before that you would like it.
