• Invalid argument when you delete a record in doubles

  I use BerkeleyDB 4.7 on Gentoo 2.6.24 - r7.
  
  I have a database with keys duplicated which I access via a slider. When I try to delete one of the records duplicate the function c_del() returns the value 22 (EINVAL) which means a flag is not valid or the cursor is not initialized.
  
  According to the documentation, the indicator (the second argument) should be zero. So the problem must be with the cursor, but him still said that the slider is very well.
  
  I have distilled the problem of autonomous code below. You should be able to cut and paste into a file named deltest.c and compile it. The comments near the top shows how to compile and run it.
  
  The code may seem long, but it's really very simple. He wrote just three records with duplicate keys and reads them. He tries to remove the second disk.
  
  Help, please. I don't know what I'm missing.

  Make a Berkeley DB error output? If this is not the case, try adding this call before opening the environment:

  envp->set_errfile(envp, stderr);
  

  Nevertheless, it seems that the problem is that you open the transactional database, then open the cursor without a transaction. Nontransactional cursors can read a transactional database (in isolation 'read committed'), but cannot perform updates. To update a transactional database, you must include a transaction.

  Here, you can open the cursor in a transaction that is configured with the DB_READ_COMMITTED flag to avoid read - lock the database entire when you scan through it.

  In the Photos of El Capitan how to record a double published in a separate with its own name and the ID file file?

  Only by exporting - with Photos (and iPhoto and Aperture) - you can have several versions of an image by duplicating the image (control - D), but this does not create an image file separated until you export - it creates a separate edit list in the database that applies to the original when you watch or export the photos

  Photos as it were its predecessors is a non-destructive control Digital Asset Manager (DAM) which does not any changes to files in the database but built a list of validation

• I tried to record some live audio. I downloaded Wondershare Streaming Audio Recorder I opened the program - but could not hear the audio I tried to play.

  Hello!

  I tried to record some live audio. I downloaded

  Wondershare Streaming Audio Recorder

  I opened the program - but could not hear the audio that I tried to play. I don't know if downloading this program is related to the problem.
  I opened Skype - and everything worked fine. I could hear, etc. But if I run an MP3 in Windows Media Player - I hear nothing!
  My sound is at the top.
  In my Volume mixer, I see:
  1 output device digital (SPDIF) bounce up and down. (but I don't)
  2 but applications: sounds of Windows, Windows Media Player and Google Chrome will not move. (but they are at the top).
  Any suggestions?

  I managed to get the results of work. I don't know where come the SPDIF.

  I downloaded a new driver Realtek for audio from the computer. This corrects the problem.
  But I still want to know what happened.

  How do I enter recorded meetings? When I click on the "meetings" tab it says I don't have permission

  Meeting records will have a direct URL, as well as meeting rooms and the content in Connect. You probably not a member of the host of the meeting or Group Admin group in this Connect account, so you do not have the permissions to access the library of the meeting.

  You will need either the host of the meeting room as you are looking for the registration you get the link and make sure you have the appropriate permissions to view, or switch the recording to the content library where it can be placed in a folder that you have viewing permissions.

• Ghosts on pages double-sided printing second on Officejet 6700 Premium e-all-in-one

  Please can someone help?

  Printer name model e-all-in-one Officejet 6700 Premium

  Firmware MPM3CN1232AR

  Software 028.000.1315.000

  Driver 09.84.00.1173

  Win 7 SP1 64 bit

  Wired ethernet connection

  Problem

  On two-sided printing, the second side of printing on all pages is ghost. This is in particular the noticebale on verticals.

  This is true for all the qualities of printing on any documents .pdf or. doc.

  I use all the HP printing paper and original cartridges.

  I aligned the print head and checks suggested on the help pages.

  I contacted HP support, which were brilliant and replaced the printer and the duplex unit.

  They suggested that it was because I was using Office 2003 SP3 and Windows 7 but I find this problem on too but not in Wordpad v6.1 .pdf files

  The problem does not occur when scanned or copied documents are printed

  Is there a solution out there on this new printer please?

  Hi 007OHMSS,

  I carefully read through a VionAiry pointer to the post of ItalSanif with links to more articles.

  There were two main suggestions as to how to proceed. I didn't uninstall the "bloatware" and back to base for the HP Officejet 6700 Premium drivers, but I installed the drivers from the series HP Deskjet 6980 in accordance with the procedure at this link http://h30434.www3.hp.com/t5/Printing-Issues-Troubleshooting/HP-7510-Duplex-Problem-y-axis-scaling/td-p/1754773 and listed below, with a few mods to include activation of unit duplex in one set of instructions.

  And you know what? This MARKET! Ghosting on the second side of all pages printed double-sided disappears to be replaced with a nice crisp clear impression. At present, all the other functions, including scanning seem not affected and function as usual, although of course the new driver (HP Deskjet 6980 series) makes the leaves of different properties.

  In my environment, I have also 3 XP machines in network connected wireless to the printer via the router and the PC Win7x64 connected by ethernet to the same router. Meant this download and the installation of the driver HP driver the HP Deskjet 6980 series for the XP PC Web page not the Win 7 x 64 because they were not present.

  I modified a bit routine and reproduce it below to help others. A/c for the original post, that was provided by the HP Technical Support. Why nobody's support services seems to know about or drivers have not been fixed I would never know.

  First turn off you will want the printer already available on the computer before you continue.

  For Win7 PC (XP is similar but not identical)

  1. Go to Start -online device and printers => then click on the "Add a printer" button in the upper left corner of the device window.
  2. Click on the button "Add a local printer" (choose this option if you do not your configuration)
  3. Check the box "use an existing port.
  4. On the drop-down list, select the option for example CN115130TP05JW , but use the correct name for the PRINTER port which is the serial number of your printer (do not use the fax entry)
  5. Now in manufacture of list on the left, select "HP".
  6. On the list of Printers to the right, select "HP Deskjet 6980 series (HP)" "
  7. "Once the pilot moved to enter in the" 'devices and printers ' window and right-click the newly added "HP Deskjet 6980 series" and select ""printer properties ' on the drop-down list. "
  8. Go to the "Advanced" tab, and then in the drop-down list next to the label of "Driver" select "HP Deskjet 6980 series.

  9. Click on the button 'Apply' - the configuration window should change it's shapea bit.

     10. in the HP Deskjet 6980 window properties, click on the tab "device settings" on the top of the window.

     11. in the list of parameters, search for "Unit duplex (for printing on 2 sides) ' and select it.

     12. once highlighted, select in the drop-down list ""Installed "; "

     13. When finished press apply

     14 now, go to what you use to print documents and select "HP Deskjet 6980" as your printer. Activate duplex printing and you should see the pages to print correctly.

  15. you can also change the name of the printer in the "Général" tab I changed it in mine to "HP Officejet 6700 with HP Deskjet 6980 pilot set shadowd duplex printing".

  I had a little problem in that, for some reason any in the document (e.g. Word / etc\ .pdf) box under the effects tab my radio button has mysteriously been on 20% until I changed it it was hard to see that there was no ghosting dialogue printer properties.

  So after complete 1 reconstruction of the printer of the original with the parts sent to HP services support for November 2012, an escalation at magnifications greater within HP (no answer) and a new printer of A...n, VisionAiry has pointed me to a solution that I had tried with DJ 450 drivers, nothing works, after a Shane_R post dated last year.

  So thanks to you and also to 007OHMSS who worked on this problem and original posters

  All I can say is that it worked for me and I am so grateful to everyone on this forum to ensure that I am sure of my eyes and mental health, looking more printed duplex printed with a shadow/ghosts and to be what they were not prepared.

  Congratulations so all round and thanks again

• If I enter an event in the calendar on a PC it will automatically be entered/synchronized in Thunderbird on a second/other PC agenda

  I entered one and the event does not appear in the calendar of Thunderbird on a second PC.

  How is a computer supposed to know what you did on the other?

  It works with email IMAP-connected because two e-mail clients display the same common shared together e-mail messages and folders, which are held on a mail server. Whenever you change, sending or filing a message, the changes are visible to all connected devices.

  For the calendar to do the same, there must be a communication channel. I don't know how you imagine a computer can arbitrarily to recognize another one of your computers and share data with it.

  You need to set up a common, shared schedule each of your computers can connect to. The solution less expensive and easier to set up a Google Calendar and have each of your Thunderbird/Lightning installations are synchronized with it. Note that since Google Calendar is supported by multiple devices, you can sync of calendar with computers using a variety of operating systems and also tablets and phones. Even supported Blackberry Google Calendar. Use this, I sync calendars on multiple computers Linux, Android tablet, a Windows laptop and an Android smartphone, and before that I stopped using it, a Blackberry phone.

  Or start porting your profile multi-gigbayte between your computers. Ugh.

• Never used front microphone input, correct Recorder window, no audio output.

  Sound input tape recorder going nowhere, an acoustic window is supposed to open, it does not work.

  There is a software that is missing in my computer portable pavilion g7.  Its media player is fine, its internet

  is fine, don't you miss that sound comes from the microphone input.  The sound recorder window is open and the

  record bar is moving because the entry varies, how do I get the sound to the speakers.  Never used this

  the option before, it might be defective from the factory.

  Problem solved.  You can not turn on computer with the microphone or other audio cable.

  If the computer does not meet the entries, you must connect the microphone or audio

  cable after connection and then a window will open allowing you to select the default entry.

• Record from an audio cassette in digital format on a Satellite A100

  I want to record music old of an audio cassette to MP3 or similar. I downloaded the Audacity software but don't know if I can actually put up a line of connection of my tape to my Toshiba Satellite A100 player. Is this possible via the microphone connection? Are there other ways to make it through one of the USB ports?

  If anyone has any suggestions I would be interested to read.

  Thank you

  Ken

  Hello Ken

  If you want to do this on professional road, you need good things to do. One of my friends bought a package to scan old gramophone records. He bought some external device and special software.

  Can I really do not remember the name of this product, but I know that it was connected on the USB port. The gramophone or, in your case, cassette player must be connected to the external device.

  Small little around Google and you will find many good products for these purposes. In my opinion the MIC port is not the best solution.

• T4i does not record more than a few seconds of HD videos?

  Hello

  The obtained T4i my partner does not seem to record HD videos more than a few seconds. It does NOT use video snapshot mode to capture video. Videos captured mode 640 x 480 can save for a time quite long... more than twelve minutes. She emptied the SDHC 16 GB card completely and still the same problem is faced.

  Any suggestions as to what can be causing this?

  Thank you

  The manual recommends a class 6 or higher.  Any class 10 will work for video.

• Double-sided print second page upside down HP6700

  When I print 2 Facer, the second page is upside down. I looked for solutions on this forum and on the net, but nothing helped. I have installed new drivers, checked all the available boxes. The one I need ('turn page' or something like that) is not found.

  I have a new HP6700, to replace an old HP6700 which made duplex very well, but became old. Why is it suddenly so hard to make something of my old printer without problems?

  I use a MacBook Pro with OS X 10.9 laptop.

  I hope someone can help me.

  Hello Cheetah12,

  Thanks for your reply. In the meantime I discovered that the most important step is NOT to install the printer via AirPrint, but using HP6700. Only, then you have the possibility to click on the duplex option and install the printer with the 4.1.2 pilot.

  The solution mentioned by Roger2499 in the following thread has helped me tremendously, after a day of frustration!

• Video recording will stop after 33 seconds

  I bought this because I was always running out of space on my iPhone 6plus. I tried to use it today to record the events of my daughter.  When I went back to see her, she stopped after 33 seconds.  I tried to take another video and the length was 33 seconds.  I decided to watch the next time.  I started the video and after 33 seconds, the Red changed record button but the meter continued as he was recording.  When I watched the video, it was 33 seconds.  I did a few tests more.  The video has stopped saving to 33 seconds every time, but the continuous meter.  Everyone knows this or make me a bad device?  It is an iXpand of 128 GB USB 3.0 for my iPhone.

  I'm tempted to simply return it.

  I spent about an hour with the support of SanDisk today.  They were able to reproduce the issue and it is related to the amount of storage left on the phone.  When I started, I had about 340 MB of free space and which equated to about 33 seconds.  I deleted some apps, so I had about 840MB and it allowed me to save up to 6 minutes but it stops again.

  I'm a software developer so that I can sort of guess what happens.  As can imagine you, it is quite possibly using storage phone (a cache?) when recording and when it stops, immediately transfers the video to disc.

  I wouldn't have a problem with this behavior as a long time I didn't know that it was a restriction.  I bought this because it says, you can record directly to disk iXpand.  128 GB is a lot of video.  Unfortunately, with the current limitation, I'm in the same position as I was before the training.  I have to remove applications whenever I want to record a lot of video.

  Another anomaly, I noticed.  When the application reached the memory limit, it will stop recording but the ticker keeps it turns out that it is still recording.  This is obviously a bug and needs to be repaired.  You would think that there should be a way to clear the cache on the disk while recording, so he isn't running out of phone storage space.  If I were writing the application, I would check to see what my free space on the phone, then make sure that I took an amount of cache, which was less than the amount of available space and then continue to clear the cache on the disk I was recording.  This would require a couple of threads and I don't know if the OS is multithreaded or not.  I hope it is, but there may be a limitation there too.

  Support said they would escalate this problem and inform me of any solution, with which they came.  I'll mark this as answered, but I'll try to update this thread if they come up with a different solution.

• HALP! My Computer Configuration double double audio needs.

  HI HI I'm having a little problem with my audio to computers. you see I have a Setup dual monitor so that even if I'm on my games my roommate can watch his movies (we have no TV) unless I have to disconnect from the game. However, audio installation does not work with that very well we have one another or both and none of us is happy that I have to configure something so that I can listen to my game on my helmet while she uses the speakers for his films without compromising either is this posible? If yes how? I have a card his rescue (ols very lol) if I need a peas and thank you

  Hi Kittygoboom,

  Unfortunately, in a configuration double monitor you won't be able to implement the dual audio. This is because vista allows only one card at a time his default and doesn't have the option of assigning speakers for a particular application.
