• How to detect the moment you press the Enter key

  I use a texteditbox on a Panel to take input from the user. I want to process the contents of the edit box when you press the Enter key in the editing area. I wonder as to how I would be able to detect the key pressed? Pointers would be appreciated. Thanks in advance.

  Hello

  Yes, if you want to do something only if the Enter key is pressed, you must implement an IEventHandler and check the virtual keys kReturnKey and kEnterKey.

• LabWindows - how to detect the unlock key?

  My application uses a reminder with EVENT_KEY_PRESS to detect the function keys on the keyboard. A routine is executed depending on the feature key. It all works very well.

  Is there a way to tell when the key is out?

  The goal is the routine to run only once and not repeated if the user is now pressed the button for an extended period of tiime.

  Ideas are appreciated,

  Thank you

  Scott T.

  Note: You can also use this method to avoid multiple keypress for any key events.

  Scott used the example of function keys.  If you also want to avoid entering repeated alphanumeric keys, 1 return your reminder of the textbox to swallow the event, is not a new key pressure.

  A new .c file (to replace the one of my previously posted project) is attached that illustrates this.

• Detect the moment you press menu key BlackBerry using the Midlet and GameCanvas

  I develop only a game and I need to detect when you press the BlackBerry menu button, so I can to pause the game. I don't want add that any new options in the menu, just pause the game when clicked. I found a lot of references using UIApplication and other things. But I use MIDLet and GameCanvas, I use a library of the rim.

• Is there a way to detect all the keys that the user clicked in AS3?

  Hi all

  Quick question - is there a way to detect all the keys that the user clicked using the AS3 code? I have pimples on my project and I want to that they be disabled once the user has clicked on it, but I wonder if there is a function that I can write that will automatically disable all keys that the user clicked once?

  Thank you!

  Here is an example where the buttons share the same handler... try it and see if it works (I can't due to not having Flash on hand).  The only problem that I could expect it not to love the evt.currentTarget is not identifiable as a particular class type, but sometimes it can't.  If this is the case there is an easy solution.

  Btn1.addEventListener (MouseEvent.CLICK, processBtnClick);

  btn2.addEventListener (MouseEvent.CLICK, processBtnClick);

  function processBtnClick(evt:MouseEvent):void {}

  evt.currentTarget.removeEventListener (MouseEvent.CLICK, processBtnClick)

  }

  If you also want to keep track of which buttons were clicked already you can store in an array...

  var clickedButtons:Array = new Array();

  Btn1.addEventListener (MouseEvent.CLICK, processBtnClick);

  btn2.addEventListener (MouseEvent.CLICK, processBtnClick);

  function processBtnClick(evt:MouseEvent):void {}

  evt.currentTarget.removeEventListener (MouseEvent.CLICK, processBtnClick)

  clickedButtons.push (evt.currentTarget)

  }

• HP Pavilion dv6-1334us Entertainment Notebook - mute button color in the key board is always Red

  The color of button mute Audio always on red although the sound turns power on and off when you press.  When the switch is turned off indicator turns white for a second.  Please suggest me the solution so that the mute button becomes red and white on the operation.

  Hello

  Try the following.

  Download IDT Audio Installer on the link below and save it in your downloads folder.

  IDT Audio Driver - Windows 7.

  One time finished, open windows control panel, open Device Manager and open sound, video and game controllers.  Right click on the IDT device and select uninstall - also, you should get a command prompt to delete the current driver, check the box allow this and then proceed to uninstall.

  When you're done, shut down the laptop, unplug the AC adapter and then remove the battery.  Press and hold the Power button for 30 seconds.  Reinsert the battery and plug in the AC adapter.

  Robinet tap away at the key esc that you start the computer to launch the Start Menu, and then select f10 to open the bios menu.  Press f5 to load the default values (sometimes it's f9, but the menu below indicates the correct key), use the arrow keys to select 'Yes' and press ENTER.  Press f10 to save the setting and still use the arrow keys to select 'Yes' and press on enter.

  Allow Windows to fully - charge it will automatically load an audio driver, but let just this complete.  Then open your download folder, right-click on the IDT Installer and select "Run as Administrator" to launch the installation.  When it finished, restart the computer again and check if the 'secret' led now changes colors correctly.

  Kind regards

• using the key to toggle the button and retain a mechanical Action

  I'll put in place to control the race of a stepper motor and I have 2 buttons for jogging forward and backward to jogging. These buttons have the mouse down and mouse events sends commands to the motor controller. The mechanical action of the buttons are set to release the latch.

  I would also use the previous Page and Next Page on the keyboard to toggle these keys. But I would like the button to act in the same way that the mouse when the button is pressed and held the button remains pressed and released with the release of the key.

  However when I press on and press and hold the button continues to activate / deactivate. Is has something to do with the repeat button, but I don't know how to operate it. Any advice would be appreciated.

  I've attached an example of how I started. The mouse down press the reverse button opens a dialog box, but the key does not work and when the key is held down the button flashes. Page Up for forward and Down to the opposite Page.

  Concerning

  Terry

  Simply use another event and manages press button from the bottom to the top in the same way. The button using local variables while active, you can switch to event.

  I don't know why you use latch action. Why not with the button until this that released and value change events?

• What is the difference this 2 examples of photos? Use function IMAQ detect circles to detect the GREEN button.

  Hi all

  Please refer to the attached 2 pictures, they are similar, just the size is defferent. (pass PNG, 5478 pass. PNG).

  But now I try to use IMAQ detect circles to catch the GREEN button. For the PNG pass, it works very well, but for another example, it is still does not detect this button.

  I also try to change the curve settings and note that entry, but still no. Another way, I also try to use function IMAQ find circles , but the result is worse that IMAQ detect circles, so give up.

  The code is detect the circles.png, copy of block diagram.

  So what is the root cause? Thanks for help.

  Hi colinzhang,

  The extraction of curve so it uniform mode, you can get the result.

  -Suggestion, if you want to use the entire image area as KING should get the size of the image, get the rectangle and convert it to the descriptor of KING. (I think this is unnecessary)

  -Be careful with the extraction of the plane, u use default color which is the Red plan. In this example, it is fine. but make sure you know what aircraft you are extracting.

• If a logging program button has been installed on your computer performs this Act of when it is installed or is able to access the previous use of the keys?

  Hello

  I received an email from a friend that I opened, it has since informed me that his computer has been hacked and thought that a virus has been incorporated into the e-mail. I have a limited knowledge of computers and would like to know if a logging program button has been installed it reads the keys historically or only from when it has been installed? Also, I found that a user account and password that I had not placed on the computer had been set and the user account setting that governs the installation of new programs was at a minimum level.

  I deleted the new user account and password and changed the UAC to the highest setting and did a scan of my computer using AVGfree, he showed a threat of conduitinstaller.exe but it would allow me to delete or archive. A search on the internet about this program shows that it is a threat, this page: http://www.removeonline.com/conduitinstaller-exe/ offers to download a tool to remove it, but I am now worried I'm going beyond my capabilities. Could I have some advice please. I'm currently travelling so don't have do not have access to a friendly computer shop is where English is spoken.

  If I do all the work financial online from the computer in safe mode, this will get me in until I can get the problem sorted.
