• How to solve problems using the event viewr log?

  Hello guys,.

  Can someone tell me how to use the event viewr log and resolve the problems or errors?

  I can solve the problems by myself, but do not know as the use of the display of event logs and information.

  Kind regards

• Structure of the event in the event structure

  Is it possible that I can have a structure of the event, which is in another structure of the event? When I run the code, I can't use other buttons. (See chart for details)

  

  Do not put the event structures in the structures of the event! There is never any reason to do so.

  Redefine architecture your code in a correct state machine.

  (By default, events lock the façade until the event ends and if you raise the event internal or external, first of all, the other event can never fire because the current event can never accomplish or is inaccessible by data stream.)

• Is there a c# example to use the event handler ExpressionEdit Custom Button control

  TestStand 4.1

  VISUAL C# 2008

  I've added the event handler for ExpressionEdit events as I would any event handler:

  exprEdit.ButtonClick += new NationalInstruments.TestStand.Interop.UI.Ax._ExpressionEditEvents_ButtonClickEventHandler (_ExpressionEditEvents_ButtonClickEvent);

  Then, I create the event handler using the syntax

  public void _ExpressionEditEvents_ButtonClickEvent(NationalInstruments.TestStand.Interop.UI.ExpressionEditButton btn)

  {

  }

  I get the following error when I compile Isaiah:

  Error 1 no overload for delegate matches '_ExpressionEditEvents_ButtonClickEvent' 'NationalInstruments.TestStand.Interop.UI.Ax._ExpressionEditEvents_ButtonClickEventHandler '.

  I guess that means that I don't have the right parameters or types in my statement of event handler, but it corresponds to the object browser.  Any ideas on what I'm missing?

  See my last edition but I think you want your handler to look like this:

  Public Sub exprEdit_ButtonClick (ByVal sender,
  NationalInstruments.TestStand.Interop.UI.Ax._ExpressionEditEvents_ButtonClickEvent

• The commands ordered in the Structure by using the event trigger

  I wrote a few weeks ago, asking for help running of programs using .NET. (Finally understood, thanks) I'm ready to move on. My goal is to control the software Filmetrics by LV in the attached vi .NET Setup works, and now I just have a problem with the controls. To start a measurement of the film, Filmetrics takes a series of Spectra of the sample, reference and background, so I would do the same thing in LV I think that using a structure of the event in a sequence, that's what I'd do, but other ideas are welcome. I want buttons only to be triggered in order and disabled when it is not their turn. From now on, when I click 'Acquire basic' façade freezes. Also attached is a version very simple what I think, and it freezes as well. Any help would be great!

  No, do not use a sequence and several structures of the event!

  Here is a possible alternative (simple draft).

• Problems using the event to write new parameter values to VISA structure

  Hi all

  I created a VI to read an Omega flow meter. It is possible to change setpoint (setpoint (0-2) SLPM) of the meter and the gas (O2, CH4,...). To read instrument I write its ID (A-Z), followed by a carriage return, for example: A + 0x0D

  I created a VI with the events to write only the parameters to the instrument when a value is changed. My VI works but from time to time, it does not write the parameter change (gas or set point). I think that is has something to do with the while loop containing an entry VISA.

  Open FMA contains parameters and VISA opend

  Case of timeout initialize writing gas and setpoint for the first time

  Other events are for the change in the value of setpoint and gas

  How can I make sure that any change of setting will be writtent the instrument?

  Thank you

  Salvation Bass,

  Well, it is true that I lose this way time-out feature.

  No, you do not lose this feature. You put in a different position.

  You must call it BEFORE your loop!

  I'm not sure that I am following on this one there

  Why are you not sure? You have a large number of constants "0d" and it would be great to see that they are displayed in HEX mode instead of the normal display mode.

  The new VI manages events sometimes... but sometimes, missing a few changes... I think it is because there is an entry in the while loop. Do you have any idea how to prevent this?

  Never, NEVER use parallel loops to write and read on the same device on your serial port!

  How do ensure you that you always get the right answer to your order sent before?

  What is the purpose of using a second loop here? A loop with no wait States?

• using the event

  Hello.

  When I try to change the value of y in my vi my theta value is 0 (the default).

  Change value of theta event is ok. But I need help value change.

  My files on the attachment.

  Thank you.

  The value of theta is not zero. However, when you change is you use the original image rather than rotated table array.  I think that you need to feed the displacement to the left register terminals to the structure of the event for the image data and Boolean.  In the picture below the arraos view the original connections.

• using the event keydown aboard animate (was: keydown event)

  I want to use the keydown event and I used this syntax that works very well:

  $(document) .one ('keydown', {Function

  If (e.which == 32) {}

  Alert ("Something");

  }

  })

  But I wonder why this syntax does not work:

  $("#Stage").on ('keydown', {Function

  If (e.which == 32) {}

  Alert ("Something");

  }

  })

  Thank you.

  KeyDown events are sent only to elements that can receive focus. Default divs do not receive focus. Setting the tabindex on a div property can lead to receive the focus. If you set the same on stage, it should work once the stage has the focus.

• How seeds Cache using the Event Table of the poll

  Hello Experts
  
  I have configured the Event Table of the poll in my PC
  Steps to follow:
  (1) table created using SAEPT. Oracle.SQL scheme in 10g
  (2) any SAEPT. Oracle.SQL by creating a new connection pool in the physical layer
  (3) configured in repository - tools - utility - OBI event Polling tables by selecting SAEPT. Oracle.SQL and gave 15 min in the polling frequency
  (4) inserted data in SAEPT. Oracle.SQL
  (5) NQserver.log checked after the time of the poll which is 15 minutes. NQserver.log was not getting updated or details about the event that occurred.
  
  You think that I missed a few steps in the configuration of EFA, if so... Please help me I need to implement on the client machine soon.
  
  Enjoy your time guys.

  As much as I know the vote event tables are used to purge the cache automatically. It is not used to start the cache.
  If you want to start the cache, the ibots use or you do like a program...

• Using the event Script to load the Excel model data for users

  Hello

  Whoever did this in the FDM 11.1.2.1.

  We want to exploit the event Script to load the data validated MDF for a standard template so that users can make some adjustments and then load the same data through the FDM? Is there a better alternative. Basically, trying to avoid making adjs data forms in HFM in view of the number of columns that we have and validations for each line required with adjustments.

• How to merge the event structures?

  I have a program of VI script that reads a text file of records and displays a structure of the event.  It works very well because it creates all the controls and indicators I need associated with the defined registry and code backend (i.e. the structure of the event).

  After I generated all this code, I copy and paste in the main VI I develop.  Everything works very well.  The only problem is that there are 100 text files from separate registry.  This means that I end up with 100 separate event structures.  Although it works, it takes a lot of space and I prefer to combine them.  However, each event structure has anywhere from 15 to 75 entries, so to do this manually is not an option.

  Is it possible to selectively merge the event automatically structures?

  I guess I could write a labview scripting routine that could get a reference to the structure of the event in VI, then merge... but part of the problem there is that there are a handful of structures of event I want to separate them just because they are not associated with the set of registers, that I mentioned.

  
  

• Coming out of the event structures

  Hello

  I need to select an exercise in a table (see table).  Goto the façade and select a line with a mouse click and place the cursor on an exercise.   Can anyone suggest a graceful way to exit out of the structure of the event by pressing the Enter key, and from the exercise that you chose a string indicator?

  Thank you!

  Unfortunately, you are using a multicolumn listbox, not a table. In order to select the individual cells, you must use a table control.

  Is attached a simple implementation, perhaps this may give you some ideas. (I also assigned the key entry to the stop button).

• Reach target FIFO in the event structure will not achieve

  Hello

  I'm just counting the time in ticks between edges mounted on two digital channels. Therefore, I use a myRIO and LabVIEW 2013 SP1 on a Windows 7 PC.

  As you can see in the attached photo, I use a FIFO extended target to switch the number of ticks between two SCTLs events to a while loop, where I want to send them via DMA to host of the RT.

  I chose this model to limit the number of DMA channel and increase the SCTLs clock (allows greater accuracy in time). The number of ticks is determined using the DSP 32 bit - built-in counter.

  However, when I run the VI no data is written to the target FIFOs scope. 'Number of elements to write' is still 127 (128 requestet), 'Number of items to read' is always zero. "ch0 post" indicates that the "real" State of the structure of the case is actually entered.

  Edit: all indicators have been added for debugging purposes. Simulation on PC indicates no error either, but I realized that no data is written to the host of RT during actual use.

  I checked the cRIO programmers guide and the high Performace FPGA Developer's Guide and do not see where I was wrong. However, it will not work.

  I would be happy if someone could help me solve this problem!

  In the lower part while loop what do you do if one of the read FIFO has expired (zero cases in the structure of the case)?

  If you set the Boolean value False in any other case (1.3) then you'll only send something to the host when the two data FIFOs received in the same loop iteration.

  If she receives a number of cycles on a FIFO in an iteration, and a number of cycles on the other FIFO in the next iteration has expired will never be null.

  To debug you may store the value 'tick count ch0 fifo' in a shift register and update only when the delta_c_ch0 FIFO does not time-out. Then you can see if this value is always nonzero.

• Flashing light without the event Structure

  Hey everybody, this question should be worded a bit better than my past. I've finally finished Core 1 and 2 so now I really have a grip on what I ask. Haha!

  In any case, I have a game custom sensors that interface via a com port and a weight which is summarized output.  The weight is then put through a business structure to give different sizes "bucket".  The various cases of output values to a slider that the user sees. This is just to give you an idea of how the load is large.

  What I need to do, is make a Boolean flag that starts flashing if she sees a significant change in weight. The weight is anywhere between 0 and 20 pounds, so I thought that a change of 1 lb or more would be a great time to activate the flashing.  I also need to only flashes for a short period of time (10 seconds).

  I tried to use the structures of the event based on the cursor and a property node. I created an event based on a change in the value and put a flashing property node, but all that did was cause my Panel before locking.

  Any ideas?

  Well without seeing your VI do is to feed your weight measurement in a shift register on the right side of your loop. Take the register shift on the left side and slide it downwards. This will give you the previous iteration of displacement registry value that you can compare up to our days.
