• NEED HELP WITH THE SHORTCUT "SHOW DESKTOP".

  Hello!

  I made a shortcut 'show dekstop '. I did it by adding this code into Notepad and save a .vbs file:
  Set shell = wscript. CreateObject

  Shell.MinimizeAll
  When I click it, it go to the desktop, just like I wanted. But when I click it again, it will not go back to my previous 'place', as the button show desktop in the windows taskbar. Does anyone of you guys no matter what code I could add so when I clicked it again, I would be back to where I was?
  It's a little "off topic", but since you are master's degree in computer science and coding, I guess that some of you can give me an answer.
  BTW!
  I am fully aware that Windows 8 has also the 'show desktop' button, but I make a shortcut for my RocketDock ;)
  Thanks in advance

  Do not try to write your own.  ;-)  No need to reinvent the wheel that is already on your system.
   
  Copy of the who that can be found here:
  "%AppData%\Microsoft\Internet Explorer\Quick Launch\Shows Desktop.lnk"
   
  You can put this shortcut anywhere.  This works.  Your just sends a command "MinimizeAll" - so what he does is JUST that.  ;-)

• Help with cursor

  I have a valid procedure work if I pass some TXN_ID inside.

  for example

  exec PM_VALIDATE (1); > > will run successfully for a single txn_id

  exec PM_VALIDATE (2500);  > > will run successfully for a single txn_id

  Now, I want to create a Proc like this

  SQL > exec PM_validate_final (num_array (1: 2500)). > > so I can pass in several txn_ids.

  I was using a loop / loop and get errors.

• Problem with cursor - will switch to a link

  I was hoping that someone could help with this.

  My dad's Mac has a problem with the cursor. It uses the trackpad and when you try to click on a link, it will not work. The arrow does not change into a symbol of the 'hand' and it can not click on it. This makes it almost impossible to navigate. It seems that the links are not recognized. He tried to use a mouse via the USB port and nothing changes.

  He tried to update to El Captain but he can't because the mouse doesn't work. The simple, restart or turn off / suite does not work. The problem persists on Chrome and Safari.

  Any help appreciated, thanks.

  Hi Irbea,

  Thank you for using communities of Apple Support. I see that you are the dad had problems with clicking on the links on his MacBook. These are some great troubleshooting steps to try to solve this problem. I am happy using.

  According to the steps that he has already done, I'll try to test this in safe mode. This will allow his MacBook making some changes and prevent the loading of the software. Please follow these steps to safe mode:

  Try safe mode if your Mac does not end commissioning

  While you are in safe mode, you may notice that the MacBook is running slower or the screen flashes.  No worries, it's normal.  Read this article for more information about this:

• iMac 27 "with the second monitor boots black with cursor

  I can't seem to find another discussion altogether as my problem starting special 'black screen ':

  New iMac 27 "retina 5K (end of 2015) running OS X El Capitan 10.11.3 with second monitor Samsung connected by Mini DP - DVI.  When starting, the two screens are displayed in black, but the cursor is available and can be moved.

  I have to make a hard stop and disconnect the second monitor to start at the login screen. Then I can reconnect the monitor and everything works.

  Any suggestions for a fix?

  So, I spent some time with Apple customer support. Several of the standard troubleshooting for problems of mystery, they came to the conclusion that there was an incompatibility of driver with the Samsung monitor at startup which is mucking things up, and I just have to accept starting with the second disconnected monitor then plug it in again after a successful login.

  Samsung does not write the monitor for Mac drivers (for some reason any), that's why the customer support figures that there is a hangup at startup. But why OS X recognize the monitor and run fine otherwise? Why only hang at boot time? And why my Mac Book Pro 2007 running the same version of El Capitan boot fine with the connected monitor? It has something to do with the Thunderbolt/mini-DP-to-DVI connection? I don't know, and I guess that Apple's Support is not either.

  I fell on a hack, which is as follows:

  1. start with the second monitor connected

  2. in the "black screen with cursor" hold the power button quite long to put the computer to sleep

  3 wake up the computer with the keyboard or trackpad or other

  4 and now the login screen will appear.

  5 log in as usual.

  6.

  I hope this helps someone. One day I'll get a more compatible monitor and it will not be a Samsung.

  They make nice dish, however.

• Black screen with cursor

  Problem:

  Windows startup but stuck on the black screen with cursor

  System:

  E7440 Dell with Windows 7 Pro

  Description:

  E7440 has a ssd msata 250g installed with an msata to sata adapter. Hard drive's MBR mode. The system works well on Windows 7 pro. E7440 comes with an msata slot, so I removed the adaptor and connect directly on the slot msata ssd. Then the black screen with cursor problem happened. Put the adapter back with ssd and Windows 7 booted up normally.

  I made a disk image of the ssd adapter so that Windows 7 is running, then restore the image to a disk sata hard. The black screen problems are out again.

  Safe mode works normally. Low screen resolution does not solve the problem.

  I also tried to copy of ssd hard disk drive, but Windows boot had another problem: session3_initialization_failed.

• Windows 7 Pro black screen with cursor on all modes and no login screen

  OK so basically, it's how, my laptop decided to me-screw right when I need to make some adjustments to my final project for next week.

  Friday he started very well in class and at the end of the course at 6:30, I stopped him. I normally don't that often stopped because I usually find myself opening upward in an hour later. But I did this time and when I got home and turned on around 9:00, it started like this:

  Screen Compaq PhoenixBIOS > Windows boot animation > black screen with cursor mobile, no login screen

  No screen connection. No sound. Not nothing but a black screen and the cursor movement. So I force shutdown and turned it back, this time he asked a chkdsk and I ran it. A ton of stuff file unreadable came and it took all night to run through it all. Tried to start again and Windows Error Recovery came and I tried all Modes of security and start normally and all produce the same black screen and the cursor with no login screen.

  Then I used my Windows 7 dvd repair to try and system restore to a week before. That's where I noticed that windows had installed a critical update at 12:00 on Friday. Tried to restore before that, but he failed. Gave me an error 0 x 80070057 and said I should run chkdsk /r and then try again. Then I used the cmd prompt through dvd repair and he has seen all these things wrong file again once recovered things then realized hours later. Tried to restore the system again. Still the same error. A run chkdsk again through the cmd prompt, then he went to clean without errors or orphaned files or anything, but it took a lot of time. I used the Startup Repair, and he has not found anything wrong either. But still the same error the system restore.

  So I looked around online for the last two days, trying to figure out and that someone said to try CTRL + Alt + Delete, the sticky shift key thing. So I tried to boot the system again, same black screen with cursor movement. I did CTRL + Alt + Delete, nothing. Press and hold the SHIFT key, and a pop-up window asked FilterKeys. Press the SHIFT key 5 times, a popup asked about sticky keys. But that's all I can get it to do. Nothing else. I tried to boot into safe mode with F8, chose, each of them and that changes in screen resolution and the words "safe mode" in all the corners of the screen. If the repair dvd's while I start in safe mode, it will open as well in safe mode, but with the same black background mode. Tried running sfc/scannow through repair invites cmd of the dvd and it says a system repair is pending and he had to restart, and then run the sfc/scannow. Tried, but it doesn't do anything when I restart except go to Windows Error Recovery asking either start in any safe mode or normally. And then it's just black screen again.

  So I am at a complete loss what to do now. After all of this mess, it seems that this Windows Update Friday afternoon did something and when I booted it upward once again, his cause nothing but problems. I think it has something to do with the display and the graphics card drivers? It's as if the thing starts but I do not see anything either because the sticky keys appears, but sees nothing else, no matter what I do. Seriously, I don't want to this junk because this is a new hard drive and I was just able to retrieve my files from my old hard drive that had epic failures as well. And I just got this new specifications I wanted as well.

  Laptop Spec:

  Compaq CQ50-115nr
  OS: Windows 7 Professional
  HARD drive: Western Digital Scorpio Blue 320 GB SATA WD3200BEVT
  Processor: AMD Turion X 2 RM-70
  Graphics card: NVIDIA GeForce 8200 M G
  Memory: 3 GB RAM

  If someone could seriously help me I would be VERY happy.

  This isn't good news.

  STOP: 0XC000021A

  Can be a difficult problem to solve, and you indeed need a technical help in a real store of the computer
  (not the leeks and the glances at a BestBuy or other BigBox stores) or system manufacturer support.

  Cause

  This error occurs when a subsystem of mode user, such as WinLogon or the Client Server Run-Time Subsystem (CSRSS), irremediably compromised and security can not be guaranteed. In response, the operating system goes into kernel mode. Microsoft Windows cannot run without WinLogon or CSRSS. Therefore, it is one of the rare cases where the failure of a user mode service can stop the system.

  Incompatible system files can also cause this error. This can happen if you restored your hard disk from a backup. Some backup programs may skip restoring system files which they determine are in use.

  Solve the problem

  Run the kernel debugger is not useful in this situation because the error occurred in a user mode process.

  Resolve an error in the user-mode device driver or system, third-party application service: Because the bug 0xC000021A control occurs in a user mode process, the most common culprits are third-party applications. If the error occurred after the installation of the new or updated device driver or service system, third-party applications, the new software should be removed or disabled. Contact the manufacturer of the software on a possible update.

  If the error occurs during the system startup, restart your computer, and then press F8 to character-based menu that displays the choice of operating system. In the Windows Advanced Options menu that results, select the last known good Configuration option. This option is most effective when a pilot or a service is added at a time. If the error is not resolved, try to manually remove the offending software. If the system partition is formatted with the (FAT) file allocation table, use a MS-DOS boot disk to access the hard disk of the computer. If the system partition is formatted with the NTFS file system, you may be able to use Safe Mode to rename or remove the defective software. If the defective software is used as part of the start-up procedure of the system Safe Mode, you must start the computer by using the Recovery Console to access the file. If a room newly installed if material is suspected, remove it to see if that fixes the problem.

  Try running the emergency recovery disk (ERD) and allow the system to repair any errors that it detects.

  Solve a problem of file system do not match: If you have recently restored your hard disk from a backup, check if there is an updated version of the backup/restore program available from the manufacturer. Make sure that the latest Windows Service Pack is installed.

  It's my generic bluescreen convenience store - you can try Mode safe mode as suggested in article
  above - repeatedly press F8 that you start. Disks of Vista are probably necessary - if you do not try to repair it, you can borrow a friends because they are not protected against copying. You can also buy the physical disks
  good system machine cheap that you already own Windows (you have to reinstall them if)
  required). You can also repair disks on another computer.

  Here are a few ways to possibly fix the blue screen issue. If you could give the blue screen
  info that would help. Such as ITC and 4 others entered at the bottom left. And all others
  error information such as codes of STOP and info like IRQL_NOT_LESS_OR_EQUAL or PAGE_FAULT_IN_NONPAGED_AREA and similar messages.

  As examples:

  BCCode: 116
  BCP1: 87BC9510
  BCP2: 8C013D80
  BCP3: 00000000
  BCP4: 00000002

  or in this format:

  Stop: 0 x 00000000 (oxoooooooo oxoooooooo oxoooooooo oxooooooooo)
  Tcpip.sys - address blocking 0 x 0 00000000 000000000 DateStamp 0 x 000000000

  It is an excellent tool for displaying the blue screen error information

  BlueScreens many are caused by old or damaged, in particular the video drivers drivers however
  There are other causes.

  Options recovery if your system is installed by the manufacturer.

• BlackBerry Smartphones help please - cursor does not not while browsing internet

  Hello

  My Curve 8520 not long ago and fear I'm kinda a dinosaur techno so please bear with me! Wonder if anyone can help with this.

  While browsing the internet my "slider" has suddenly stopped working. My "cursor" - the small black arrow - is still there but when hover over an area of research for example and "click on" my trackball that nothing happens, even if the little hand symbol appears on a link if I "click" the trackball that nothing happens. I discovered I can press return when the hand appears and it goes on the link, but this is unnecessary when only the arrow appears.

  Any assistance received with gratitude

  Ken

  Its the kind of thing that could possibly be fixed by a battery pull.

  With the BB powered, remove the battery and keep it for a few minutes. Let us know how you go.
