• Full of blackBerry Smartphones key lock?

  Hello. Is enybody please knows how to make a lock key on the curve?

  I mean not a key lock, as if the locking of the upper keyboard button is pressed. This, after pressing a button is always displayed a message, that the keys are locked and must unlock them. This consumes a lot of battery through pressure on the keys at random if your handheld is in a Pocket, etc.. I want to make a such keyloch as if your handheld is in the original case. Hope so, it is possible without the case.

  Thanks for your advice!

  ... I discovered, its potential affecting only the pocket computer sleep mode. To do this, I have to press the right top key on the top, not the upper left button (it's only for the locking of the keyboard is not complete as I described).

  If the laptop is in sleep mode, it continues to receive everything (phone calls, emails, sms, etc.) but the buttons are locked except the gren and Red call and menu buttons, and back buttons. You wake up the Pocket since the previous day by press the button top right again (same way as you do this the simple keylocking).

  I hope this helps.

• Connection num lock problem

  Here's my problem:

  I am running Windows XP on triple boot with Ubuntu and Backtrack. Caps lock Num Windows turns on whenever I start. Lock num on my computer is physically damaged (even if this is not the reason why turn on num lock), which means that I can not connect.

  I use Ubuntu right now. Since Ubuntu has the ability to open and modify Windows .exe, I open regedt32.exe and modified HKEY_CURRENT_USER\Control Panel\Keyboard "InitialKeyboardIndicators" = "1".
  I also modified HKEY_USERS, yet my registry did not have a "Control Panel" button, so I created myself: HKEY_USERS\. Default\Control Panel\Keyboard "InitialKeyboardIndicators" = "1".

  I also tried another method that was to create a file called "numlock.vbs" and write the following:

  Set WshShell = CreateObject ("WScript.Shell")
  WshShell.SendKeys "{NUMLOCK}".

  And paste the file in All Users\Menu Démarrer\Programmes\Démarrage. Nothing has worked so far.

  In accordance with the following article, the values only legal "InitialKeyboardIndicators" is 0 (off) or 2 (market).

• Ctrl key locks

  System: Windows Vista Home Premium Service Pack 2
  Model: HP Pavilion dv9700 Notebook PC
  Processor: Intel Core 2 Duo CPU T5450 at 1.66 GHz
  Memory (RAM live): 3.00 GB
  System type: 32-bit

  Probably not related to the info above, but it can't hurt someone help.

  TL; DR: My computer keeps thinking that the ctrl key is pressed when it is not. Is there a way to solve this problem permanently, or my keyboard is simply broken?

  FULL ARTICLE:

  Today, I turned on my computer and the start screen where it tells the brand of computer and all ordered options and avoidance for the analyses of the system has really had much time to disappear and load the OS screen. I been a little perplexed and worried about it, but it doesn't seem to be a problem.

  Just in case, I did a virus scan with my Avast! Free antivirus and it tells me there is no problem with my computer. My unstable feeling, put at ease, it seemed OK to me. I open windows live messenger and tried to start talking to my friend, but it wouldn't let me type. Switch to Firefox, because I tried to find a solution, I found that I couldn't type out there either because all these windows as save the page and find jump upward.

  I discovered by pulling my on screen keyboard that my ctrl key has been locked, even if I wasn't pressing it at all. I temporarily fixed several times by pressing the CTRL on the keyboard on the screen or by pressing the right CTRL key on the physical keyboard several times, but only one of the two could never work. I determined that it was left CTRL that was causing the problem.

  Now my left ctrl key has had a history of bad luck with me. First the PAC itself came out a year ago, and then the little spongy rubber under a thing done as well. But the button still works if I press on the space where the key used to be. I don't know if the missing key could be part of the problem, but I doubt it because it has never been a problem before.

  I checked my settings, and sticky keys is not the problem. I doubt the sticky keys would be able to assign the same computer outside the OS anyway. I can't find a button or setting change to get this to stop, and the CTRL just randomly sticks again on the computer without warning, even when I'm not in contact with the laptop at all. It's really in the way of myself using my laptop, since I can't even type easily. Writing even this message was very difficult, given that the SHIFT is very inclined to press ctrl as well for some reason any, but which may or may not be the fault of the absence of a case key for my key Ctrl. As I was saying before, however, that the absence of Carter has never been a problem, even when I used Shift.

  My computer keyboard has changed often other languages for this reason also, and I had to go into my settings and erase all my shortcuts for changes of language because of this problem.

  I had to resort to the help of my shift for caps and random lock record and bookmarks and find windows pop up without warning. Backspace erases sometimes whole lines because, with the CTRL key, BACKSPACE deletes words, no letters.

  If someone could give me an answer, I would be really grateful!

  Hi Chrysfaic,

  You can try these steps and see if it helps.

  Step 1:

  Try pressing both keys CTRL left and right at the same time and see if that release CTRL.

  Step 2:

  a. go to start / settings / control Panel / Accessibility Options Options /Keyboard.

  b. turn off CTRL lock if it is enabled.

  c. If this solves and to avoid future problems, press "settings".

  d. disable "Press modifier key twice to lock.

  e. turn "disable automaintenues keys if 2 key at the same time." Or disable "use shortcut".

  For more information, see the following article:

  Facilitate the use of the keyboard

  Step 3:

  Clean your keyboard.

  If you're still having problems, then you may need to replace the keyboard.

  Hope this information is useful.

  Please suggest.

  First of all, thanks for posting the code that allows us to reproduce your test. It is essential for such problems.

  Because the primary key is global you will not be able to use

  INCLUDING INDEXES
  WITH VALIDATION;
  

  And you need to add the primary key to the temporary table

   ALTER TABLE DEMO_INTERVAL_DATA_LOAD_Y ADD CONSTRAINT IDX_DEMO_ROLL_Y PRIMARY KEY (ROLL_NUM);
  

  The Exchange will work. You must rebuild the primary key after the Exchange.

• ENQ: TX - conflict in line for the foreign key lock

  Hi all
  
  My DB is 11.2 exadata machine.
  
  I've got to get a case and don't know how to explain it.
  
  session 1:
  
  create the parent table)
  ID number primary key);
  create the child table)
  parent references ID number,
  name varchar2 (20));
  insert into values parent (3);
  
  session 2:
  Insert children values (3, 'aa');
  
  Session 2 crashes.
  
  I'm curious to know how oracle knows that 3 in the parent table can be inserted? Otherwise, why not oracle comes throwing ORA - 02291:parent key is not immediately that I have ' insert into child values (3, 'aa');
  
  Best regards
  Leon

  How about this scenario
  Session 1:

  1. insert into parent(id) values (3);
  2. commit;
  3. delete from parent where id = 3
  

  Session 2:

  1. insert into child values (3,'aa');
  

  What a result for the session 2 you expect in this case?

  Let me repeat a sentence of my previous post:
  Theoretically, the general rule is that account required to a SQL statement (whose key foreign is just one particular case) two different operations should only be serialized when both transactions run a kind of DML statement that could be contrary to the assertion.

  Now give me a scenario where two operations in effect running a kind of DML which could be contrary to the assertion of FK:
  -session 1 deletes a parent, which could be contrary to the assertion of FK because there may be child-lines 'under' parent.
  -session 2 inserts a child, which could be contrary to the assertion of FK because there could be a mother line for that child.

  ERGO: sessions 1 and 2 in your scenario above must be serialized.

  Still once, this was not the case in the scenario of the OP: FK assertiveness could never be breached by what session 1 (insert a new parent).

  >
  I don't see what that has to do with "modes of locking for insert, update, delete statements" (what do you mean by there btw?)
  >
  Thus,.
  Oracle of the second session always will go, lock in exclusive mode the entry created in the child table and then try to check for the presence of record in the parent table by reading it in shared mode (why reading is in shared mode must be clear from the scenario described above). Because the parent record is locked in exclusive mode, it cannot hold a shared lock, so he waits. So, if we need a different result if the first session of the insertions and deletions a record, Oracle, stumbled on the lock, you need to know what type of operation has led to the blocking.
  Something like that...

  The problem with the implementation of the Oracle of the assertion of FK is it locks data to serialize an assertion of the FK validation.
  Theoretically, this is the wrong approach. When dealing with simultaneous transactions and validation of constraints in several rows, it should return a predicate to first lock and then read the other rows (without lock somehow) to validate the assertion. Scientific research for this return began in the 1970s: http://dl.acm.org/citation.cfm?id=360369

• macOS Sierra caps lock problem

  I have put 2 languages in my macbook air mid-2013. After having the upgrade to Mac OS Sierra, my macbook air cannot change text or uppercase nor lowercase.

• Key command problems, Macbook Air

  In a first time, I realized that 'cmd + 2' not was not to give me a '@' but instead would turn tabs on chrome, same for the hashtag. But the "cmd + c" or "cmd + v" were operating normally.

  I went into system preferences and tried to restore all the default keyboard settings, still nothing. I had to go the keys command and Option before it finally worked. But then new problems, even if the "1,2,3...' buttons now worked with cmd I have to use ' alt + c/v ' to paste instead of the normal cmd + c/v. Also, before I had to press cmd + a keys "F1, F2, F3...". "to make them work (such as the volume, for example), now I have to use fn + 'F1, F2, F3...". »,

  It happened all of a sudden, I have a few theories of how it happened: I slept last night on my keyboard, I kept my laptop in a few days (software because of this problem maybe?), and finally, I connected my pair of speakers today (a thought that never posed a problem before).

  Although I managed to find a temporary solution, I want to get my keyboard will work as before. Anyone got a solution please?

  So, apple won't let me delete the question, if someone wants to know more about this problem here:

  As I said I fell asleep on my keyboard, because I spent the last hours of 10 studies, my brain was so tired that I forgot the '@' key is "alt + 2" and not "cmd + 2", I really spent two hours of navigation for the 'solutions'.

  So many children, go to sleep and do not leave final kill you.

  At soon xx.

• MacBook Pro fn key locked somehow WE

  I managed to make my Macbook Pro 9.1 behave as if the fn button is LIT. I pressed the fn key to make the keyboard to behave normally, is not a viable solution. I tried different combinations of fn, control, option, and command keys (well, all, really), both hold and just typing, reset the SMC, reset the Pram, restored the defaults in system preferences - keyboard. I am at a loss.

  Various Google searches suggest that others have had this problem, but I have not found a solution online.

  The problem arose after that I have had left the MBP asleep for maybe a week and then could not exceed the stage of password to wake up. Forced feeding. Restarted, took forever to get my password to enter (I understand why, now that I realized the fn key problem) and now I'm looking for an answer.

  Any help gratefully received.

  Just an update...

  I plugged a USB keyboard borrowed a Mac Pro on my MBP and it works properly. Makes me think that there is a problem of real hardware with the MBP keyboard. BTW, the problem with the position of blocking ON fn key also affects the operation of this door on the operation of a USB mouse connected to the Mac Pro keyboard and the trackpad on the MBP.

  I just noticed that the Mac Pro keyboard does not have a fn key. Wonder if that could be relevant to the operation of the USB keyboard.

• Z580 - WLAN adapter problem

  I've got Lenovo IdeaPad Z580, with Core i7, 4 GB of RAM and 1 TB of HARD drive processor.

  A few months ago, I noticed that my BONES sometimes would freeze (make this beep sound freakin ') if I moved my computer too fast in my office (weird). She got worse a few weeks ago and seems to be somehow connected to my wireless network adapter.

  It especially simply - nothing works. Switch WLAN disappears from the BIOS configuration, etc., like it wasn't even there. If I'm lucky (as I am now), it would work somehow. All of a sudden appears again in the BIOS etc. I can even use it on my Windows 8, but... If I propose a little my laptop, it will suddenly freeze and restart causes WLAN adapter not in the system at all, or the connection is de-energized ("metered" stuff etc.). Restart adapter according to the results of system in "find no WLANs", wlan switch endangered or gel.

  I tried to reinsert the WLAN card, it sorta fixed stuff when I did it for the first time, I had a week or two without a problem, but he returned and reintegrated support is no longer.

  First question what I can do with this adapter WLAN problem?

  Second question is - while doing all this thing reinserting, my screws are a little bare now (but not completely, it is possible to get them unscrewed without any problem) because I have not noticed my screwdriver is broken and ruining. My laptop is still covered by the warranty? I do not have removed or broken any warranty seals in the process well, just the screws.

  I forgot to mention, by WLAN adapt is Atheros AR9485WB-EG.

  Information on repair mentions setting parts disconnected.

I try to drag the ground, but he thinks that I lifted my finger and the lines are red, as when guess you the wrong pattern, and the lines can get crazy, the point shooting randomly on the lock screen, making very tempremental. When this happens I just click the lock button to close the display off, and then try again. Even after I do that, it still does not work and the lock screen will become crazy... Any help/tips? I can load a video if that helps...

  I have this problem with my phone in the morning. I think it is do to the fact that I have my AC make my really cold room. If I leave the room for a few minutes, that I have no problem. It only happens when it has been in a cold room.

• Screen lock problem

  I have a 64 GB iPhone and last week, I updated to iOS iOS 8.xx 9.1. After the update, my phone slow sometimes and the screen has not moved even I scrolled across. The problem is, when you locked your phone with touch support, screen, it should be showed black white screen and locked instantly, but with my phone, sometimes when I blocked my phone, it shows the black white screen and then the background appear for a while and then the locked phone. Could someone help with this problem? Is this a bug or something?

  Could just be a bad copy of the iOS software. Save it to iTunes or iCloud, plug it into iTunes, restore as a NEW and test again. If the problem is resolved, then restore your backup, if the question comes up, the iOS and the phone is very good, it's probably something corrupt in your backup. But most of the time, a restore will solve your problem
