InsertionPalette activex control key down event

Hi,
Can any one know how to get the key down event of InsertionPalette activex control.
I have handled the KeyDownEvent but it is not fired while the control is active and key is pressed.
regards,
Ceaser

  • How to separate "Key down" event from panel and numerical control

    Hi, All
    I have a vi proecess key down events for panel and  a numerical control in this panel. the application will do: 
    1. when panel is focused, user can use "up" and "down" key to driver some hardware.
    2. when the numerical control has the focus, "up" and "down" key will change it's value as usual.
    somehow the second one did not work, because the panel "key down" event was trigger as well when I use "up' "down" key inise the numerical control. 
    then I used "Key down?" of numerical control to block the "up/down" key. But the first time when I run the Vi, the panel still got triggered one time. 
    any suggestions on this? test code attached  in this post too. 
    thanks

    This works for me in 2014.  In short, you just need to check to see if your numeric has the focus.  If it doesn't, then you process the key value.  No need for any other event here except for the stop button.

  • CS3/MAC key down events

    I have a plugin which presents a dialog and does some keyboard input,
    and under mac/cs3 ONLY, indesign is capturing and acting upon key
    down events before the plugin sees them.
    Oddly, key UP events are being passed through normally.
    These events are being delivered to the plugin by the
    mac toolbox function WaitNextEvent.
    Is this a known problem?

    The last time I read about the Mac event manager, WaitNextEvent was deprecated in favour of carbon events. Maybe InDesign now also follows this path.
    http://developer.apple.com/documentation/Carbon/Conceptual/Carbon_Event_Manager/Concept/ch apter_2_section_4.html
    Anyway, bypassing InDesign in order to invoke WNE is bad style. Make yourself familiar with IEventHandler and alike.

    If you're working at Extensis then at least one of your users now has found the problem ... . Could be a different reason though, I just saw this post:

  • When is Key down event case triggered

    Hi all,
    In event structure there is an event <this VI> key Down? 
    When will this event be triggered... i.e will this event be triggered only in case of a keyboard entry... ?
    Or in case i use a barcode reader, if data gets populated in a control on the Front panel through the barcode reader will this trigger this event...?
    Thanks

    The Key Down event will only be fired when a key is pressed on the keyboard.  If you want to fire an event off of a Front panel control, you can either use a User Event or a property node called Value (Signaling).  This property node will cause a Value Change event to trigger when the value of the Front panel control changes.
    Cheers

  • Key down event handeling when the VI isn't active

    Hi
      I've written a simplel VI that increases or decreases a numerical indicator depending on which key is pressed on the keyboard. But this only works when the VI window is active (the titlebar is blue and not gray). Is there anyway to listen for the key-down event even though the VI is not active?
    In advance thanks

  • Key down event in background

    Is there a way to make the key down event in the wait event structure run in the background when labview is not the focus? Also what is the difference between the "key down? event" and the "key down event"? I couldn't find a good answer in the LabVIEW help.

    tst wrote:
    To expand a bit on RF's answer, while you can't use the event structure to register for key down events in other windows, there are some potential options:
    You could use the input VIs to poll the keyboard (and you can have a loop which will use a user event to send each new key to an event structure). The main problem with this (and it's a big one) is that it is unreliable. You would have to poll quickly enough (probably at ~20-50 Hz) to have a decent chance of being sure that you're not missing keys and even then it's not guaranteed. The other problem is that you don't know which window was actually in focus.
    You could try getting the window messages from the other window. I have no real experience with Windows messaging, but my understanding is that this will probably require you to write a custom hook in C to get it, but it's possible that this is also possible with the standard Win32 API functions. Even if it is, this is probably not something you want to get into to, but you could try looking it up.
    Actually this Windows Messaging already exists in LabVIEW:
    http://zone.ni.com/devzone/cda/epd/p/id/4394
    However there is a few issues.  It only partially works in Windows 64-bit, and you have to know the handle to the application that you want to intercept key downs for.  I did a quick test and I was able to detect the KEYDOWN event in another VI that was running for for some reason got an error when I tried to get keydown on notepad.  This method would eliminate polling if you can get it to work, and because of this you shouldn't miss any key presses.

  • Key down events

    Hi,
    I've been working on code for handling a flash-plugin inside an existing application, and have been looking at getting the flash player working with the Cocoa/CoreGraphics API.
    Thus far, I have plugin loading, focus, mouse handling events all working. But then key events don't work consistently - on some flash applications, the key down events work, but on most they return a '1' but the flash app doesn't respond.
    This is most odd, and a pretty esoteric type of work - I don't know many people who get this kind of work, and it's hard finding people who can share their experiences of this.
    I've been going through the NPAPI docs on the mozilla website and copying a lot of the handling code in WebKit, Chromium and Firefox, but none of it seems to help any more - my handling code works the same way as that does, but the responses for key down events are different.
    So, this is just a last try before I go crazy - has anyone ever seen anything like this before?
    Thanks,
    Tom.

    Well, it is a problem with Flash Player and not Flash. I don't need an experienced Flash developer.
    Seriously though, the nature of the question is so esoteric that I doubt there are many developers anywhere who could give much advice.
    Thanks anyway.

  • Detecting external keyboard Key Down Events in Ipad2 without EditText Field.

  • Detection of the control Key down when application start

    I need to detect if the control key is down when my program start. This program was created with CVI 5.0. Would you tell me how to do it under WIN 9x et NT/2000. Regards

    Normally, for any other key you could just set up a callback function for your panel and set up a case statement for the EVENT_KEYPRESS value for the event type. Or do the same on the initial control that has focus. However, this does not work for the control key, because it does not generate an EVENT_KEYPRESS. Therefore, giving you no option through the normal CVI user interface capabilities.
    Now, you might be able to detect the keypress through windows messaging if you use the function InstallWinMsgCallback found in the Programmer's Toolbox library (toolbox.fp in cvi\toolslib\toolbox) and set up a callback function to look for the message that the control key generates for a window. Other than that, you might have to use some Windows SDK functions, that wait for a keypr
    ess to happen.

  • Key down event to start something an stop arbirtrary

    hallo,
    what I'm trying to do is to start an event on key down an do a loop , something like move an axis for CNC , and this until i press an arbitrary key again.
    i have already a while loop an an event structure so it would be good just to add something withtout large modifications.
    have anyone an example code for me , please.
    i've looked already in a lots of posts but i can't find anything usefull for me.
    many thanks in advance

  • Weird Digital Display Key Down events

    (Using LV 8.51)
    I have a slider with the digital display shown.  The slider is restricted to 0-50 (I32)  I want the user to be able to type 0-50 in the digital display only.  I have formated the display as %2d and set all limits.  The display allows the user to type any arbitrary number of characters as well an many letters.  I figured out the random letters are the allowable numeric prefixas such as k (for kilo).  I need to not allow the user to type anything in the numeric display except [0-9][0-9].  I figured that I could filter the key down? event.  This did not work.  I placed the key down? event and the key down immediatly restricted the typing to a single character.  What did I do wrong or is this a bug.  Is thare a simpler way of restrictin g the imput (NOT Coersing which is done on the data but limit the input characters).  Thanks I am stuck on this one.

    I hope I am doing something wrong but I dont see it.  It seems that independent of registering for the keydown event the action of the slider changes.  I have attached an example.

  • Safely switching focus during backspace key down event?

    I have a simple form that I'm building. It has a variable
    length list
    of entries, and I'm using a TextInput for each entry.
    Because the list is variable in length, I'm allowing the user
    to
    delete elements from the list. One of the ways they can do
    this is to
    press the backspace key when the cursor is in an empty
    TextInput. I
    am handing KeyboardEvent.KEY_DOWN and checking for the
    backspace key,
    to accomplish this.
    The problem I am having is that after I remove the deleted
    TextInput,
    I want to leave the focus in the TextInput above. I can do
    this using
    'setFocus', and that works fine, however it seems that the
    backspace
    is still processing, and so after the focus is set, the
    content of the
    TextInput is delete which I don't want.
    To get around this, I've created a one-shot timer with a 0ms
    delay
    which changes the focus after the KeyDown event has
    completed.
    My workaround is successful, but feels very heavy handed. Is
    there a
    better way to achieve the same effect?
    Any advice would be greatly appreciated.
    -Robin

    I guess one of the way could be adding KEY_DOWN listener on
    focus and removing it from other input fields at the same time.
    adding/removing listeners is pretty fast.

  • Dialog not on display list getting key down events

    Hi all,
    I have a listener on the stage listening for KEY_DOWN events.
    I show a dialog (MovieClip containing a TextField). Click a button
    on the dialog to close the dialog. ("close the dialog" == remove
    the MovieClip from the display list - the dialog instance is still
    around, which I think is part of the issue)
    Now, the stage's listener no longer gets KEY_DOWN events
    until I click somewhere on the stage. The dialog's text field is
    getting the key events. (I don't normally add a KEY_DOWN listener
    to this dialog, but I did as a test to see if it was indeed getting
    the events.)
    How can I get the stage to get KEY_DOWN events again without
    clicking it first? There seems to be no way to explictly set
    keyboard focus that I can find.

    Hi. What happens if you simply request focus to the
    MainTimeline? That should seem to do the trick. If focus is on a
    removed element (but it still has focus, which seems weird), the
    the stage won't get any events.
