• Is it possible to connect and reconnect a keyboard with the computer on?

  I have now 2 iMacs Office sitting side by side on my desk.  Since I want a keyboard with a numeric keypad on the right side, I found the only way to get that with an Apple keyboard with a USB connected keyboard.  Therefore, when I want to knit back and forth between macs, I have to unplug the keyboard of one and then plug it in another one - and back.  It would be a hassle to turn off mac whenever I need to do that, so I was wondering if it would damage a computer.  Two usb ports are usb powered external hubs.

  There is no problem with the device on a keyboard with the computer and plug in another.  It's only external drives that need to be removed before unplugging.

  Is there more than one user account on your computer? If you

  the fact that it is one that rises at the start, a piece

  similar issues or is it just works fine on shut down?

  The question may take some trial and error troubleshooting. This

  may include some basic startup keyboard shortcuts for

• HP 15 laptop: problem with the touchpad and the key "stuck."

  Hello!
   
  Last weekend, I have an irritating problem with my HP 15 laptop. Bought two years ago and upgrades to Windows 10 a year ago.
   
  First of all, my touchpad started to not work properly. It "freezes" and I can't use it until I click the ESC key, but it doesn't last and "freezes" again a few seconds later. Then, everytime I open a window where there is a text box (Start menu, edge browser, Control Panel, etc.), the number 5 is entered automatically and permanently, as if the button 5 has been blocked. I did a quick check and button 5 do not seem physically stuck.
   
  Yesterday, I restored the system to the factory settings, so I'm back to 8.1 for Windows and then upgraded to Windows 10. Everything seems to work fine, but this morning, the problem was back. Is there something I can do? What is the problem caused by Windows 10 or the computer? Should I restore it to Windows 8.1? Everything worked great til last weekend, I don't know what that was.
   
  Thank you in advance for your help!

  It could be a driver problem to be able to look at that for you, I need your model number. I wish I could give you an answer or not, but at this point without the troubleshooting results and the model number, it is difficult for me to say.

  I can say that if everything works in point 8.1 of Windows without problem, the driver TROUBLESHOOTING is a great place to start. Please try to follow these steps for the keyboard and the touchpad of troubleshooting:

• my wireless keyboard does not work on the letter and number keys.

  It seems to be connected to the computer, because it does not work on the control button and snooze sound

  Hello

  -Have you made any recent hardware / software changes prior to this question?

  -What is the brand and model of wireless keyboard?

  Method 1: run the hardware troubleshooter.

  Open the hardware and devices Troubleshooter
  http://Windows.Microsoft.com/en-us/Windows7/open-the-hardware-and-devices-Troubleshooter

  Method 2: update a hardware driver that is not working properly

  (a) open Manager devices by clicking the Start button, click Control Panel, click System and security, and then, under system, clicking Device Manager. If you are prompted for an administrator password or a confirmation, type the password or provide confirmation.
  (b) in the list of hardware categories, find the device you want to update, and then double-click the device name.
  (c) click on the driver tab, click Update driver, and then follow the instructions. If you are prompted for an administrator password or a confirmation, type the password or provide confirmation.
  http://Windows.Microsoft.com/en-us/Windows7/update-a-driver-for-hardware-that-isn ' t-work correctly

  Method 3: resynchronize your device with the receiver
  
  To resynchronize the mouse or the keyboard with the receiver, follow these steps.

  Note When you synchronize the mouse or the keyboard le clavier with the receiver, place the device near the receiver and store other keyboards and wireless mouse at least 6 feet.
  1. press the button on the receiver and check that the light on the receiver starts flashing.
  Note Some newer devices from Microsoft are subject to their receiver and cannot be reset. If your device has a button, go to method 2.
  2. If a dialog box appears on the screen in seconds, follow the instructions that appear on the screen. Otherwise, continue to the next step.
  3. press and release the Connect Channel button on the bottom of the mouse or the keyboard.
  4. check the green light on the receiver. A continuous green light means that the synchronization was successful. If the problem persists, repeat steps 1 to 4.
  5. for the Wireless Notebook Mouse: this issue can occur if the micro-switch on the bottom of the mouse is not released. Use a PIN or pen to try to release the button, if it is pressed.

  Hope this information helps.

  Objective: Create a file name variable with the County and the date

  Error: get a lot of error. Do you know how to change my code?

  Question: how to create a file name variable with the County and the date?

  Mini code:

  std::string * rawfilepath;
  std::string * rawfilename;

  rawfilepath = "./shared/documents/";
  RawFileName = rawfilepath + 'rawlog -' + 0 + '-.txt ';
  QFile file (rawfilename);
  If (file.exists ()) {}
  rawfilenamecount ++;
  RawFileName = "./shared/documents/rawlog-" + rawfilenamecount + "-.txt ';
  }

  Thank you for your attention,

  Thank tzander reminding me the idea. Method of cascades is not good for me because all of the kernel code is written by Native. If I change the channel to QString, I need to change a lot of codes.

  Solution is below.

  While (access (rawfilename, F_OK)! = - 1) {}
  rawfilenamecount ++;
  sprintf (format, RawFileName, rawfilenamecount);
  fprintf (stderr, "file exists");
  }

  Rawlog = fopen (rawfilename, "w"); Save the file in a specific path.
  fprintf (rawlog, "System Time (ms)" "");
