If Boolean statement

Hey,.

It is a simple question just have not worked on it yet, I want my if statement to check if the Boolean is true so here is my code.

name: Boolean = new Boolean();

MC1.addEventListener (MouseEvent.CLICK, myMouseEvent);
function myMouseEvent(event:MouseEvent):void
{
name: Boolean = true;

If (name: Boolean = true)
{

Code to run...


}


Syntax error: expected paren right before the colon.

probably a simple explanation that can't do this.

Thank you.

When you declare a variable, you need to do just that, declare it as a variable, otherwise, you are the same error as before and designating a type when you should not...

var myboolean:Boolean = new Boolean();

If you make false immediately before the test if it is false, there is no reason to test if it's wrong... it is.  What follows is not necessary...

myBoolean = false;

If {(myboolean)
myBoolean = false;

}

  • LabVIEW basics - Cahnging Boolean State question based on the input signal

    Hi all

    I would like the State to change the Boolean indicator based on a simulated sine wave signal. I have partially managed to do this but need help to develop it.

    See the attached vi. At the present time changes Boolean false to true when the value of the signal is greater than 8 or lower than-8.

    The focus I need is:

    Once the signal passes more than 8 (and the Boolean value becomes true), I hope it becomes false again to a value of 9, but only after the peak value was passed or when the signal is down.

    Similarly on the negative side of the graph, I want the Boolean value to become reality at 8-under, stay true until after the peak value was passed and then back to false when the value is greater than-9.

    Any suggeastions?

    Thank you

    While Crossrulz responded, I had a little look.

  • How can I test the Boolean State of the button action?

    Hello
    in as2.0, how can I test the Boolean value if a key has been pressed or not?

    I have a function simple im trying to work with like that...

    button_btn.onRelease = function (success: Boolean) {}
    If (success) {}
    trace ("we pressed the button value is true");

    working with Boolean values in this way is new to me - pointers will do - thanks!

    I got it! Here's a quick run down in a table format, hehe

    cry [0]...
    [1] create a Boolean variable
    [2] create your switch case statements correctly //which I have...
    [3] condition your Boolean in case statements
    [4] and then create your button managers
    [5] if the Boolean value is true, then say stream_ns.seek (0)

  • Boolean logical operation

    Hello! Recently, at work, I was responsible for creating the code that returns something on two Boolean State. Something like: If Boolean has and Boolean B, return if Boolean is and B no Boolean etc something else.

    At first I thought that the best way to do it would be a formula node with the return value is passed through a bunch of if else statements. Then I discovered that Booleans are not supported in notes formulas and forms knots are designed for writing formulas, and not for current programming, that makes sense.

    I came with two ways to do it, but I felt that they were both quite stocky and they suck if I had more than 2 Boolean values my logic on the basis. Here is the code with the two different methods.

    I feel like this is an operation that would be much better to do it in an if else statement in code and I would like to know if there is a better way to do this in LabVIEW.

    Typical in LabVIEW is to combine Boolean both in a table, then use of the boolean to number table. This will give you a value between 0 and 3 (included). You can use a single case statement, or you can create a table of values of output desired and use it as an index in the table, or if there is a direct mapping of the enum, you can simply convert that number to the enumeration type.

  • NVL equivalent to Boolean instructions?

    Hi guys,.

    just had this question asked by a delphi programmer - apparently assignments to variables can be performed in a manner similar to the following:
    v_assignee := <boolean statement> : <result if true> : <result if false>
    or basically a nvl, how if it evaluated the accuracy rather than nullness.

    I use Oracle for quite awhile and know any such function (what wrong with a case or if statement?) but I thought I would ask anyway - such a thing exists in Oracle?


    that is to say:

    Not exactly; NVL covers only 2 values, not 3 like the above statement.
    NVL2 is a closer analogy.

    I use Oracle for quite awhile and know any such function (what wrong with a case or if statement?) but I thought I would ask anyway - such a thing exists in Oracle?

    No, in SQL, I think that is the closest thing. As you say, what's the problem with the CASE? It is not as concise as a: b: c, but it is also enigmatic, more.
    For specific types of conditions, COALESCE, DECODE, NULLIF, NVL and NVL2 have their uses.

  • Retrieve the State of the menubar control station

    So I don't see the menu bar items can be defined as type = "check", which means that it behaves like a checkbox with a Boolean State.

    < label menuitem = "Foo" type = "check" enabled = "true" / >

    My problem is that I can't seem to understand how to reference this object to retrieve its State. If the type of radio, it's all right to the front where the declaration contains a groupName attribute to retrieve the value. Is there something similar that can be done to get the Boolean status of an item of type check?

    Don't know what you use to capture the Click event, but it is an example. You need access to the atrtibute of the rocker.

    private void menuHandler(event:MenuEvent):void {}

    Alert.Show (Event.Item.@Toggled);

  • NEITHER USB 6008 AI acquisition and generation of pulse

    Dear users of LabVIEW,

    Greetings for everyone. I am a beginner of LabVIEW and I have a problem that I solved partially. I would really appreciate your help and suggestions that I searched for days without a bit of luck. The problem is as follows:

    I am the acquisition of tension HAVE (continue) 4 to 8 accelerometers. In the meantime, I send you a digital output signal each time when you click on the sampling frequency (i.e. 1000, 2000, 3000,...) If the sampling rate is 1000). In other words, try to send a signal of output digital (at a frequency n Hz) at intervals of 1 second (depending on the material). To make the digital output signal begins to blink a LED every one second. In addition, I need to write signals (voltage) AI and the LED blink timestamps PC (software) separately. All stages of the above are followed in my .vi program, but the real hardware/software level operations kill my timestamps. In other words each LED flash timestamps are not accurate, when I use LabVIEW measurement file express VI (the difference is not at least to the third decimal). In addition, the timestamp is kinda OK when I disable the file LVM write VI. Onemore thing I've noticed is that physically the LED blinks every second two times, I feel it's because of the shift register and loop delay of a second. Is there a way to control the speed of blinking (i.e. Boolean State must change to every 500ms without delaying the inside while loop).

    Results and comments:

    LabVIEW 2011 .vi, timestamp of files with or without generator of LVM (express VI) files are all attached. Please note that there is a considerable amount of drift in the consecutive timestamps when the file LVM generator is used, on the other hand there are derivative of 0.001 ms when the file LVM generator does not. The reason for horodateurs PC have is about aligning the various measures or observations or events to global time scale.

    Please give me any suggestions or help me do at least accurate to milliseconds in VI of witten. Finally, is there any USB DAQ module relatively inexpensive which allows to send an impulse to directly from channel impulse of output digital channels when the "n" sampling frequency Hz is obtained by level of material which could all be accurate, so that the software timer is completely reduced to a minimum. Although there are very material sophistiated of NOR, but our goal of this project is to build and test the system profitable.

    Thank you and I really appreciate your time and effort inavluable. Have a great weekend!

    Just change the samples to the constant playback at the entrance of the DAQmx Read.vi from 1000 to 500.

  • Position of the active cursors

    Hello world

    I'm programming an application with sliders on my graph XY. They are visible or not according to Boolean State keys programmed event. I just need to retrieve the position of the visible sliders and then transform to a material substance, but it seems that I do not use the right solution. I'll be back all positions of cursors, even the most invisible.  How can I tell the difference between the visible and the other ones? I said I can't do it one by one because I have a lot of sliders this is why I use the cursorList as you can see on the relative picture.
    Any idea?

    Best regards
    MartinO.

    The list of cursor does not distinguish between visible/not visible. It will always return all cursors. If you want just the ones visible then you must browse cursors and read the Visible State. Something like this:

  • Capture the key of the second keystroke

    I need to capture, the keyboard of the second sequence of keys (and ignore the premiera), I need to be '0' or '1' to start the movie.

    On first use, it works very well, but after that my film back to the beginning, the keys are not recognized more...

    Here's the script for this part. Maybe something is wrong with the way he ignores the first strike?

    import flash.events.KeyboardEvent;

    stage.addEventListener (KeyboardEvent.KEY_DOWN, reactToKeys);

    function reactToKeys(keyEvent: KeyboardEvent): void {}

    If (barCodeFirst == 1) {}

    If (keyEvent.keyCode == 48) {}

    trace ("Zero");

    } ElseIf (keyEvent.keyCode == 49) {}

    trace ("One");

    } else {}

    trace ("nope");

    }

    } else {}

    (barCodeFirst = 1);

    }

    }

    Basic troubleshooting: paste a trace statement to the first line of the event handler to see if it is still running.

    Also, never use numbers to store the Boolean State. You should be setting barFirstCode to true, not 1.

  • NullPointerException error

    Hi guys,.

    There are a number of things you should re - visit in your code:

    1. it seems clear that MyCheckBox is your own JCheckBox extension? But you do not extend JCheckBox, as in:

    class MyCheckBox  extends JCheckBox {
    

    ... but why you must extend JCheckBox I can't think your purposes described

    2 set up your database connection whenever you update or select is probably not a good idea - unless a lot of time can go between the use of the database.

    Instead have a separate class or method that makes this configuration and returns a connection once (again, at least that the app is sitting for long periods of non-use)

    3. I do not understand your JCheckBox configuration in jButtonActionPerformed, but I can understand why you might get a NullPointerException.

    It is not a good idea to create your objects JCheckBox (or MyCheckBox FTM object) in the case of the methods in code. Set them up in advance.

    4 where to start the new Thread/practicable?

    Just before executing your SQL statements would be a good idea. Take a look at the link posted in a previous answer.

  • Apparently easy AS2 code that I can't understand...

    Long story short, I just want to be a mc (acting as a button), when I click it tells an instantiated mc to move one image, and if I click on the button again the mc instantiated goes back one frame. Another way to look at it is, click on advance once an image, click on go back again a framework. Clicking repeatedly alternates.

    Using AS2 I am a bit confused and I tried from Google and I ask my friend who is more than an AS3 coder. Initially, I put the var function in the event after the one (release) which gave me no errors. My friend said that if the var statement is in the result will always be true.

    I must admit that I am certainly not familiar with conditional statements and this will be my first attempt to do so. My confusion was how does the know what true and false. I was told to put forward =! before would be inherent in the mechanism of switching based on the Boolean statement active.

    var before: Boolean = true;

    We (Release)

    {

    If (towards front = true) {}

    _parent.keyboards.nextFrame ();

    } else {}

    _parent.keyboards.prevFrame ();

    }

    Forward =! front

    }

    You are welcome.  AS2 can be written in the timeline like AS3... If some Protocol obliges to use code on(), who defined it needs to be educated.
