  In the attached VI why looping force the type of data while the other does not?

  I'm guessing that you have created the Enum on the front panel.  If you right click and create an indicator, it corresponds to the type and be an enum.  LabVIEW represents enums as U16, but because the types are not the same (for example, your enum has 3 values, but a U16's 65 536 values), LabVIEW automatically converts value (or converts) the smallest representation (enum) in the largest value (U16).

• Why PL/SQL procedures does not allow users to enter data dynamically at run time?

  Dear all,

  I tried to do a procedure that will search for a group of approval in our database that matches.

  (1) the number of levels

  (2) the number of users by each level

  (3) the id of users by level

  entered by the user.

  I tried various methods to receive user input dynamically at run time, but in vain.

  Finally finished my procedure allowing the user to enter the parameters and then executes the procedure, to which these parameters are passed as arguments. (1 variable for the number of levels and 2 userdefinedarrays with the number of users by level and level respectively)

  Why PL/SQL procedures does not allow users to enter data dynamically at run time?

  Hello Sir,

  My question is that if I'm going to say, the number of levels 5, is there any way by which, at runtime, the procedure prompts me to enter at the start of the number of users per level. Now as soon as I get the number of users per level can I do the procedure ask me to enter the nicknames of the members of each level. I mean, something like a invite.

  Thank you

  There is no way to do it in SQL or PL/SQL, because not SQL PL/SQL is a way to get user input.  User interaction is a job for your front end, like Zlatko tool suggested in response to #5.  If your front end tool is SQL * Plus, you can use the substtitution variables, as Jarkko showed in response #6.

  New event with the plu date September is saved without date. Only the photo and name of the event. Older date is saved normally.

  

  The event is recorded without date 1.11.2012

  

  

  When I put date of 1.9.2012 everything is ok

  

  The solution is in the location settings in windows. I changed the English localization settings and everything is ok.

  

• launch event is not caught, why?

  Hi all

  I need therefor. When the mouse is over the image, I need to enlarge outside, to shrink to normal size. But if the mouse is moved quickly, the launch event is not caught. Any solution on this?

  Code here:

  <? XML version = "1.0" encoding = "utf-8"? >
  "< mx:Application xmlns:mx ="http://www.adobe.com/2006/mxml"layout ="absolute">"

  < mx:Resize id = "myResize" / >

  < mx:Script >
  <! [CDATA]
  public function rollOverHandler (): void {}
  imgViewer.width = imgViewer.width * 1.1;
  imgViewer.height = imgViewer.height * 1.1;
  }
  
  public function rollOutHandler (): void {}
  imgViewer.width = imgViewer.width / 1.1;
  imgViewer.height = imgViewer.height / 1.1;
  }
  []] >
  < / mx:Script >

  "source ="dolaemoney.jpg"rollOver =" rollOverHandler () ' rollOut = "rollOutHandler ()" / >
  
  < / mx:Application >

  It is most definitely get managed (the deployment that is)... Replace your code with the following:

  public function rollOverHandler (): void {}
  trace ("ROV");
  myResize.stop ();
  imgViewer.width = 400;
  imgViewer.height = 400;
  }
                
  public function rollOutHandler (): void {}
  trace ("RO");
  myResize.stop ();
  imgViewer.width = 270;
  imgViewer.height = 270;
  }

  Note that the trace message "ro" occurs whenever you unroll.  You need to just play with the mechanics of the effect of resizing so that things behave the way you want.

• Why the STOP button stops not timed loop.

  Hello world

  I had a rather complicated code launched against me. I had to change program action unique (and many other things) when ACQUIRING a button has been clicked making timed measurements. I was able to add the time... but I want the loop to stop once you click on the STOP button.

  I have attached a very simplified version of my code.

  So if you start and press the ACQUIRE the program generates random numbers (to simulate the measure) and records them with a device ID. The program stops once the total is for instance in the default settings after 20 sec.

  But it does not stop when you press the STOP button. MY QUESTION: why not?

  FOR INFO:

  In my actual code, there are 10 events instead of only 1.

  It doesn't have to stop immediately, inbetween iterations (because I already tried to include the timed stop Structure VI and it did not work either).

  I also used the execution to highlight, but it did not help me.

  Thank you for any help or suggestion!

  Lisa

  Lisa,

  First of all, thank you for explaining clearly what your problem and to present a simplified program.

  The problem with your program is very simple. The loop inside the structure of the event begins when the acquisition: Mouse Down event occurs, which seems to be what you wanted. The default condition for the case of the event is "front Lock (defer the treatment of the actions of the user) until the end of the occurrence of the event." This is controlled by a checkbox at the bottom of the evetn installation dialog box. What this means is that the stop button is not recognized until AFTER the event is complete.  BUT the case of the event cannot complete until the while loop stops.

  The Solution: Move the loop outside the case of the event.  Generally speaking, event must not contain any code that could take more than a few milliseconds to run and certainly should not depend on the user's other actions to complete.

  Look at the design of producer/consumer models (events) for advice.  Also learn how to use queues to pass data between loops rather than local variables.

• Why do I get message not delivered on my SMS

  Why do I get message not delivered on my SMS

  Because they were not delivered for some reason any!

  Make sure that you connect to your cellular network (if you are using SMS), and that you have a data connection as well (if you use iMessage).

  In addition, call the intended recipient and ask that they check the same.

  You can also turn off and on your phone.

  Then test some messages.

• Structure of the event does not not at the exit of a Btn dialog box

  Hi all

  I have here a simple VI. I want to blow a One button in the user dialog box. I want VI to wait until the user clicks on the OK"" button. When we click on the OK button the VI should pop another dialogue a button and stops when you press the Ok button. The VI does not stop. The value change event is not captured by the structure of the event. Can't really understand why.

  What OK button you are wanting to trigger structure of the event?

  1. as you have connected it the case of the event is related to the OK INDICATOR on the front panel.  You don't have an OK button on the front panel. The OK button in the dialog box is not easily accessible to the structure of the event.

  2. programmatically change an indicator does not raise an event to change the value.

  3. you can use a Value property node (signaling) to trigger the occurrence.

  4. There is almost always a better way to do what you want to use an indicator and a value (follow the signs).

• use the queue and event to read data from two series mean

  Hi all

  I'm reading the data of two serial port using QUEUE AND EVENT but not sccusess. can someone help me?

  I use LABVIEW 2011.

  att my project.

  regrads.

  You stop the second for loop using cluster of error which means that your upper and lower loop stops when you press exit but not the one in the middle. In theory, you should send a queue for loops below when you press the exit button and also make sure that you shoot hunting all queues before closing everything.

• value chain control event does not trigger change

  Hello

  I am trying to scan a barcode with a barcode usb HID scanner. I use a structure of the event to detect the change in the value of a control of the chain. When I scan the barcode, the chain control updates on the front panel, but the event does not fire until I left on my mouse on the front panel. can someone help? See attached vi

  Your barcodes are probably fixed length. When you get an event, check the length. If it corresponds to the length of the barcode, then process the data, otherwise wait for more characters.  This can be treated very quickly in the case of the event.

• UserChanged event does not run

  Why the event UserChanged without executing when the user is changed with the IEngine.CurrentUser property in an operator interface?  I noticed that it will run when the connect/disconnect methods occur, but not when it is modified directly.

  Also, is it possible to force this event programmatically, so runs the code in the callback associated with this event (such as a work-around?).

  Thank you

  Paul

  TS 4.0.1

  LV 8.5.1

  Paul,

  for the event to not be fired because IEngine.CurrentUser is a property of the engine and the event is controlled by the Application Manager. Therefore, changing the value of the property does not create the event on its own.

  If you work in a user interface, it is recommended to use the Manager commands; the application Manager provides a method of "Login":

  Connects the user by running the front-end reminder LoginLogout. This method does not wait for the callback to run. Use the ApplicationMgr.UserChanged event to determine whether the connection was successful.

  The downside is that the front-end LoginLogout creates the default value of connection dialogby. If you do not want to have this dialogue, you should consider to replace with your own front end. But please do not change the default reminder, but substitute using the directory of users!

  hope this helps,

  Norbert

• Data Driven Conditions, alarms &amp; Actions

  I have a Multiple-severity rule configured with 4 alerts (Normal, warning, critical and Fatal). the alarm goes off when a certain percentage is reached. Ditto for criticism and Fatal. My question is, what triggers the normal alert in a Data Driven rule. I currently have it set to email me. I was under the impression that when a warning, critical or fatal alarm is resolved, the normal alert would fire and send me an email. My warning, critical and Fatal rules do not seem to be pulled because I don't get emails. However, my normal alert is fired. There is no place in the normal alert to set a condition, only an alarm message.

  Thank you

  Hi Jeff,

  Gravity Foglight several rules are State. This means that they are triggered when the State of the condition. Monitored objects start to the Normal State. If the Fatal, critical or warning condition is true, the State of the object will be set according to the severity and of the actions of severities will trigger.

  The same rule may be reassessed at the same severity for a number of iterations, but no further action is triggered that rule corresponds to a different State. This could happen in two ways:

  1. The rule evaluates a more severe State to true. for example, Warning-> criticism or Fatal, critical to Fatal
  2. The rule evaluates the Fatal, critical conditions and warning false

  In the first case, the State of the object passes to the more severe State and the associated actions that will trigger more severe condition.

  In the second case, the State of the object returns to normal, the alarm is deactivated and the actions associated with the Normal State are triggered.

  In this context, the answers to your questions are:

  1. The Normal State is triggered when an object that was previously in Fatal, critical or warning States is re-evaluated and fatal, critical conditions and warning to evaluate false.
  2. Normal conditions should only fire after a warning, critical or fatal returns to normal.
  3. It is possible for a State Normal shoot without warning pre-existing, critical or fatal rules of shooting first, but this is unexpected behavior that probably indicates a bug. A package of support with the recording of debugging is probably necessary to diagnose this problem.

  The foregoing is based on the actions defined to trigger on "enter". It is also possible to set up actions on 'Out' of a given State, but this feature is rarely used. Like "Heading" shares "Exit" are also triggered when the State of an object changes.

  Kind regards
