How to detect the channel delete event in a custom device

I am creating a custom device and want to detect when you press the button Delete (X) in the system browser.  This is so I can increment or decrement a counter in a folder (where the channel is under).  I saw no option in UserEvent loop options.  How do I detect that a channel is deleted?, I'm sure it's easy, but I can't seem to understand.

Thank you!

I recommend usually do not do that... If you can avoid it. For example the parent folder can do if everything is just a child get point-> the size of the array to count channels rather than storing a property that could get out of sync. I always try to design my devices do not store the property values for things I could go get.

That being said... Sometimes you don't have that. You want an actionviondelete: https://decibel.ni.com/content/docs/DOC-30447

  • How to detect the number of created quickobjects

    How to detect the number of quickobjects created? quickobject are quickbox2d.

    Basically, I have a timer that will countdown to 4 seconds and it will create a falling ball, it will get removed when she falls down. However, I want only there so that if more than 5 bullets are in step, it will cease to create until it is less than 5 to start creating some balls again. Is there a way I can do?

    It's the timer to create the ball

    If (! _ballCreation_timer) {}

    _ballCreation_timer = new timer (4000);

    _ballCreation_timer.addEventListener (TimerEvent.TIMER, _onBallCreationTimer);

    }

    aQuickObject.destroy ();

    REMOVE FROM THE CUSTOM TABLE

    _balls_array.splice (_balls_array.indexOf (aQuickObject), 1);

    }

    check the length of _balls_array.  If it is greater than 5, do not create another bullet:

  • How to detect the color pages in a PDF file?

    I use a plug-in of Acrobat C++ read/modify a PDF file.

    I need to get the total number of pages in the PDF file and the page numbers of the pages in color.

    So far, I was able to get the total number of pages using PDDocGetNumPages() with no problems.

    However, I can't find an API that lets me know if a particular page is color or not. Is there a way to do this?

    Thanks in advance!

    But what happens if there are RGB data which means black or grey (R == G == B), that means black or RGB?

    There is a code sample in the SDK to browse content in the PDF file, and then you can get the color space and color of each object.

    But you really need to do background research on the colors & spaces to achieve this properly.

  • How to detect the event mouseclick-control

    I am trying to relax the max property Z on the scale of a graph of intensity to be changed from the front panel.  In the VI attached, I use an increment/decrement control and just detect a value change event (without taking into account the value of the control).  It works very well, even if it's a bit of a hack.

    I want to make them much more functional.  My main question is this: How can I detect an event 'control-click '?  I intend to use this event to change the max of graphic intensity by a factor rather than an additive value.

    A second quick question: on the numerical control, is there a way I can get rid of the number in the display space and leave only the increment/decrement buttons?

    Thank you

    Allan

    Are you talking about the button increase/decrease on a digital control?  I thought you had Boolean separate to increment and decrement. It's hard.  You can't be the PlatMods when using a value change event.  You will maybe make your own controls inc/dec and update a digital indicator rather than use a digital command.

  • How to detect the number of channels on an oscilloscope?

    I have various models sitting around the laboratory, some two-channel, a few four-channel oscilloscope.  I would like for my program to be able to detect the number of channels is available.

    I can just tell my program how much string is available based on the model number, but is there a VISA command to request scope directly what channels he has?  I would also be able to ask what, if any, ability to function math there.

    "all drivers of the oscilloscope must return the instrumentID after initialization, and that should be enough to know the number of channels.

    What Albert was referring to is that all compatible drivers IVI in their base class interface have an attribute/property that indicates how many channels has the scope.

    If you don't want to use the driver of the IVI for the scope then maybe download some of the drivers and check the source code to see how they calculate this dynamic repeated capablity.

    Flex will not take focus away from something unless the discussion is going on elsewhere.  Maybe assign focus to a "submit" button or something like that.  Capture phase listeners can see mouse events and affect the focus.
