  Hello

  Thanks for posting your question on the Microsoft community.

  Thank you for details on the issue.

  Windows may freeze if multiple programs are running at the same time or if Windows is infected by a virus or malware.

  I suggest you to execute the resolution of performance issues and check if that helps.
  Reference:
  Open the troubleshooter of Performance
  http://Windows.Microsoft.com/en-us/Windows7/open-the-performance-Troubleshooter

  It checks issues that could slow down the performance of your computer, such as how many users is currently connected to the computer and if multiple programs are running at the same time.

  Please also run Microsoft safety scanner to check and remove any viruses or malware that may cause the problem.
  Reference:

• Duplex charger HP 8620 document Mac error - 'the scanner could not complete the scan.

  Hello

  When the analysis attempted double helped since the document feeder, I get the following error:

  the scanner was unable to complete the scan

  If I don't select duplex option, the printer scans very well. I really need the duplex feature was that the printer was purchased for.

  I uninstalled the printer, reset and all that gubbins.

  my setup is the following, configure the printer as wireless on mac osx mavericks last generation last drivers/HP utility. Ipgraded for the latest firmware of the printer also. all without success, and now support is not open until Monday

  For more information on this...

  So I think that I managed to fix it. Different solutions etc. then forums all about I thought I would include it here. This is the steps that I found to work for Mac OS x 10.9.

  I need to follow the steps:

  1. Remove the power cable while the printer is turned on wait about 15 seconds and plug it in again.
  2. When the installation of the printer using the selection HP not the Airprint, which is added by default on Mac OS x 10.9 - capture screen attached and operating.

     

     If everything is working great and then if not go to step 3.

  3. If the printer is already installed with AirPrint go to the printer main & scanners, right click in the box on the left where you printer is displayed and click on reset printing system. -This will remove all printers found here also.
  4. Download of the latest version of the software for your operating system
  5. Install the software, restart the computer.
  6. Download the latest firmware, if it is available for your printer
  7. Add your printer and follow the steps 1 & 2. It should work and allows you to copy double-sided.

  Don't know if this is a limitation of the software or drivers but ADF allows up to 300 dpi, as the manual scanner allows all the way up to 1200 dpi.

• HP OfficeJet 6700: Could not complete the scan

  Printing now works fine.

  I was in the Middle I digitizes a 7 page paper on the feedbed in TIF format, (which I did successfully several times before) when he leaves the analysis. I had to pull the output printer page.

  I could click on new scan and go to the properties of a couple of times, but it is not yet complete the scan.

  What happened to my computer?

  Hello and thanks for trying to help.

  They were always connected wireless.

  I does not solve the problem, after having paid Best Buys Geek Squad $100 to register for a program.

  It remote access to my computer. He had to remove all the drivers for my printer and then reloaded them and it worked fine.

  Published by: santi January 5, 2012 04:04

  Hi Santi

  Rather than read the index and the ROWID can visit the table, the CBO has decided it's cheaper to do:

  Get all the ROWID of the index xyz_IDX1 on the CHARGECODEID column via a scan interval for two values of interest (2.29)

  Get all the ROWID for all entries using the Index Index fast Full Scan on the NBFC_xyz_PK index on the CHARGEID column (as this is the only column to select)

  Do a hash join to determine what ROWID exists between these two indices.

  The index view $ _join$ _001 is the result of this hash join, which allows to extract only CHARGEID values that are of interest.

  All necessary information can be obtained from these 2 indices and so avoided visits to the table. A column should not be in the WHERE clause of an index to consider.

• It is faster to index an initialized matrix or use a tunnel auto-indexed, both inside a loop - what happens?

  WARNING: MATLAB user here.

  Note: This is a question of LabVIEW, not a matter of MathScript.  I just use MathScript to demonstrate the point.

  This is background to the particular question.

  In MATLAB if you want to calculate decent efficiency then you want previously declared tables and want the built-in functions.

  This means that it's slow:

  ICT

  for i = 1: 10000

  ENTRIES = rand;

  end

  T1 = toc

  (t1 = 0.266, so 37.6 elements/MS)

  and it's faster

  % start before the next loop, but not copy - paste with it because it slows down it waaaay

  Claire x

  ICT

  x = Zeros (10000,1);  % If not the ', 1' and then it overflows of memory to MathScript

  for i = 1: 10000

  ENTRIES = rand;

  end

  T2 = toc

  (t2 = 0.205, items so 48.8/MS)

  In MathScript, it is an improvement of 23% at run time.

  ratio = 100 *(t2-t1)/t1

  (ratio = - 23.3)

  When I use LabVIEW for the same thing, I get:

  

  which leads to a computation time of 269 ms for about 10 000 000 elements in a vector.  (Note that this is literally ~ 1000 x faster than MathScript).  He created elements of k ~ 37 per millisecond.

  If I change out for a created matrix indexing, then the time is strange.

  

  When I run it for 10 elements of k, or about 1000 times less, then he finished in approximately 30ms, or approximately 333 items per millisecond.

  When I run it for 100 k items, or about 10 x more last run and 100 x less than the previous vi, and then it ended with about 5000 ms, or approximately 20 items per millisecond.

  The best construction and replace it is running hundreds of times slower, and it is perhaps running ~ 1800 x slower.

  Here's my problem:

  One of these things is 1800 x slower than others.  Why is it reasonable?  Why is-111 x reasonable?  Here are the simple changes.

  I love that LabVIEW is literally 1000 x faster than MatLab in certain tasks.  I need to understand why, in some cases this multiplier 1000 x falls down to a 2. 4 x DECREASE.  Intuition I have is not only wrong, it's incredibly bad.  He's wasting the 1000 x multiplier of speed that I am very happy with.

  My thought:

  If I did it in assembler to nickname the first loop is as follows.

  I point to the stack, call the random number generator to get a value on the stack, incrementing my counter, check if it's 10 million, update my pointer location and iterate.

  The second loop would be as follows:

  Point battery, I write a zero, incrementing my counter, test whether it is 10 million, update my pointer location and iterate.

  then

  I will return to the beginning of the location of the stack, call the generator of random numbers to get a value on the stack, incrementing my counter, check if it's 10 million, update my pointer location and iterate.

  The report of the runtime for loops would be the time difference of calculation-writing-increment of a (pseudo) random number and THEN a zero against writing incrementing from zero.  I expect it to be somewhere between 2 x and 10 x.

  There are BONES.  Perhaps the algorithm to calculate a random number has many steps, like thousands.  Here is the difference between On-die, L2, RAM and disk.  Given enough items I would expect things to have to go through the bottlenecks and get slow.

  You have to shift registers when using him in place element structure. I don't know why, but it is much faster (and a more exact comparison) when you use the shift register.

  

• Unable to complete virus scanning - unexpected errors

  Hello

  Couldn't find this name on Google, it is spelled correctly? Could be malware.

  Right click on it - properties - Details tab you can determine the author? Is legitimate?

  The reason that you can not remove it is that's probably because it loads at startup.

  No one program cannot be used to detect and remove any malware. Added that often easy

• MSE does not complete its scan - blue screen of death

  my laptop has been running and playing pandora through chrome. I came back to it and saw a blue screen of death. immediately, I restarted and opened the MSE. went to "Refresh" for the latest definitions. ran the scan. at about 99% completion, the machine restarts and says windows (I'm using win 7 pro) is not stopped correctly. I start again normally and try to re-run the MSE. same thing happens to about 99% scanned, it restarts and says the same thing all over again. I noticed that my MSE changes color at the top of the screen to yellowish and said that your computer is not protected.

  Help, please. Thank you, Steve * address email is removed from the privacy *.

  Moved from the center of Community Participation.

  Hello

  1. What is the exact and full blue screen of death error?
  2. Do you have other security software installed on the computer? You have installed don the computer registry cleaners?

  If you have another antivirus software installed, then the most likely reason for this problem is that you have installed entirely or partially on the PC security software conflict. Remove all other computer security software. You may need to use a cleaning tool to remove your previous security software.

  Also, make sure that the PC clock and calendar are correct.

  If this isn't the case, then you will have to uninstall/reinstall MSE.

  You should be able to remove MSE of the control panel. Uninstall problems see: http://answers.microsoft.com/en-us/protect/forum/protect_start/uninstalling-mse/a63b8c4b-58ed-437e-8086-fa08d80725a4

  It is best if you restart the computer to make sure that uninstall is finished.

• Query not using Full Scan Index

  Hello world

  I'm on 11.2.0.3.0 AIX 6.1.

  There is a query such as:

  Select: sys_b_0 | Count (distinct (column_name)) table;

  that goes for the analysis full table. The column was values separate only 104 with not NULL values. To save memory buffer gets, I created an index on the table with the column used in the query (i.e. whose distinct values are recovered).

  The problem is that even after the creation of indexes and force the flag index that it does not use the full scan of the index. The provided indication is correct in syntax and was the only clue in the query, so there is no question of conflicts with others.

  Can anyone suggest me what I might be missing?

  Thank you

  It seems to me that if print_branch_code is defined as nullable in the table. If this is the case, the optimizer goes for a sweep of index, even if there is no real NULL values

• Wait signal generator complete the scan list before sending the next command

  I am writing a program for Agilent E4421B signal generator scan to list between a range of frequencies (ramp up to the maximum frequency and then back down to the original frequency) specified. The signal generator has only a list of 401 points, which is a problem when I want to wash over a wide frequency range. To work around this problem, I would like to perform several scans of list in a row. However, I can't figure out an effective way to "say" the program to wait until the previous scan has finished before sending a new order of scanning for the signal generator. Any ideas? For reference, I use Agilent ESG drivers series LabVIEW.

  Thank you!

  If you use standard VISA calls, I would say just that send the scan command, but add; * mutual fund? (operation ends?) make a query.  Then, run a VISA to read what's coming.  This indicates to the device to send a 1 to the output buffer when the scan is complete (or just about any other operation, also).  As you are waiting for a response, your computer will wait the amount of time to wait so he could see a response, it is not less, your way with the exact amount of time - no more - to be actually taken.

  A few warnings:

  (1) make sure that the time-out is longer than the length of most slow scan.

  (2) there are variants of the '1' being returned.  I saw '1', '01', and even "1.00E + 3" therefore to allocate more than one byte to read."

  Hello

  Under Printers Scanners &, click on the Plus sign button and you should immediately see the printer listed as like Hello.

  If the printer is not listed as Hello, which can occur because of a configuration of the router or limitation, any support from router Hello (aka. Multicast) and some provided with such support disabled by its default configuration.

  Please specify your model and brand of router, so I can try to guide you further.

• Questions Windows Fax and Scan

  Hi all

  After modernizing our systems to small business from Windows XP to Windows 7 x 64, we were unable to use the toolkit provided with our printers Canon MF Fax/scanning, we converted in Windows Fax and Scan

  So far, it's working fine, but I have three questions that I can't find answers to...

  1. when a received fax is deleted, where is he?  I can't to the trash, and sometimes, I delete a fax by chance and here to recover, but can't find it

  2 can we somehow add a comment/topic to faxes received to allow the best management of incoming messages?     Would be really nice if the Inbox can be sorted by sender or subject

  3. can you inbox / outbox backed up/archived/export made?

  Thank you

  Hi Mike,.

  Thanks for posting your query in Microsoft Community.

  I understand that you have some queries about the Windows Fax & Scan utility. I hope you find the following useful answers.

  1. There is no "deleted items" bin ior recycles n Windows fax and scan, so unless you have a backup system, you cannot recover the deleted documents.

  2. No, you can't add a comment/topic to faxes received to allow the best management of incoming messages.

  3. Ideally, the location of the Inbox of fax is C:\Users\ (username) \Documents\Fax\Inbox.

  I would also ask refer you to the following article to understand Windows Fax and Scan.

• Question simple signatures!

  Hello team Cisco,

  I have a simple question for you to do. Why disable most of default signatures? Have no explanation? Why are obsolete? What signature should I allow and what should I disable?

  You could help me, please?

  Kind regards

  Rodrigo Alves

  My thoughts without order.

  set to disable by default signatures

  a. a few signatures are vulnerabilities that are very old. Signatures would be necessary only in rare cases. Affecting the default signature can save resources to the IPS.

  (b) the quality of a signature is perhaps not very high. If the signing is enabled, a large number of false positives generated may be creating frustration for the admin.

  I could go on, but I think you get the idea.

  What signatures need to be activated?

  Signatures that meet your environmental requirements must be enabled. If you are a shop all Windows, you don't need signatures Unix oriented. In addition, you must enable the signatures that match your organizations security policies.

  I would start with the signatures of what Cisco has enabled by default. Feel you comfortable alerts, false positives tune and address problems, allow more signatures.
