Continuous sampling method get unreasonable values

• Why can I not make a continuous sampling of port 0 on USB 6216?

  I have a USB-6216 of NOR. I try to capture digital signals using port 0. However, the only way that I can function is samples on request. If I select N samples or continuous sampling, I get the following in the DAQ SignalExpress Wizard error message both Labview 2011. What I'm not doing correctly?

  Error-200077 occurred to the DAQ Assistant
  
  Possible reasons:
  Requested value is not supported for this property value. The value of the property may be invalid because it is in conflict with another property.
  Property: SampTimingType
  
  Requested value: sample clock
  
  You can select: on request
  
  

  
  

  The 6216 not having a sample for the e/s digital clock as you can see from reading the specification, every time you try to use one, you will get this error message. Thus, in LabVIEW, whenever you want to do a reading, you must call a single value DAQmx Read mode single sample (or the DAQ Assistant, configured the same way). How many samples per second you take is going to be highly variable due to windows being nondeterministic.

• How to get the values of page jspx (view layer) to the custom method defined in AM

  Hello
  
  I have 1 text field and 1 submit to homepage.jspx. When I click the button submit, it will call the custom method defined in the 'Module of the Application' java class (ApplicationModuleImpl.java). Can I know how to get the value of this text field in this custom method.
  
  I used the getter and setter method, however it didn't work as it is defining the value correctly, but get method returns null. Its not allowing to use FacesContext. Could someone please tell me how to get the value of the text field to this custom method (that is, using ADFContext,... something like that)
  
  Thanks in advance

  User,
  you have mixed up something here. Bean (as you did) cannot use the module of the application. They belong to different layers.
  I suggest you to look at some first tutorials (http://docs.oracle.com/cd/E18941_01/tutorials/toc.htm) or watch the developer guide http://docs.oracle.com/cd/E16162_01/web.1112/e16182/toc.htm and take a look at some of the videos http://www.oracle.com/technetwork/developer-tools/adf/learnmore/adfinsider-093342.html

• How to get the value of a variable to bind a client method of the AM?

  Hello
  
  I have a VO based on a variable binding. This binding variable is associated with an element on the page. When the user fills the element that the binding variable is written, the query is executed. This method works.
  What I want now is the following. With a second button, the user runs an exported AOS action method. In this method, I want to get the value of the binding variable that has been put forward.
  How would I do that?

  You can get the variables bind currently set on the object view as follows:
  catServiceDurationsVO has the reference to the VO
  VariableValueManager vm = null;
  VM = catServiceDurationsVO.ensureVariableManager ();
  System.out.println (VM.getVariableValue ("BindVariable"));

• Is it possible to collect data from two separate modules of cDAQ NOR while game mode "continuous sampling?

  I am using a cDAQ with NI 9237 module and one NEITHER 9205 and LabVIEW 8.6.1. The two arecoded of modules using the DAQ Assistant in LabVIEW.

  I would like to simultaneously read data guarantee of deformation (NI 9237) and data LVDT (NOR 9205) in order to operate a piece of equipment from laboratory to different load profiles. However, when I try to run the VI with two Assistants DAQ continuous sampling value, I get an error saying that the 'resources are not available."

  To work around this problem, I tried to have both alternate between taking a series of samples. This method is insufficient, as it produces choppy data that controls a machine cannot be invoked.

  Sorry if the words I have used are not good. I'm kinda new to labVIEW.

  Thank you

  I assume you are using cDAQ-9172 chassis.

  This was just an analog input synchronization engine, which means that only HAVE task can run at a time.

• Get the value of the variable inside the function from the event (EventListener)

  How to get the value of the variable inside the function from the event. Variable has been declared as a function of external events.

  var StringVar="sample";
  
  
  
  
  myButton.addEventListener(MouseEvent.CLICK, myClickReaction);
  
  function myClickReaction (e:MouseEvent):void{
  StringVar="other sample";
  }
  
  trace(StringVar); /* it gives me "sample" value and i would get "other sample" value */ 
  

  This strange because if it would be the trace of a normal function would give me good result.

  var StringVar="sample";
  
  
  function myClickReaction():void{
  StringVar="other sample";
  }
  
  myClickReaction();
  trace(StringVar); /* it gives me result as i wanted to have - "other sample" value */ 
  

  I also know method of passing of arguments depending on the event, but it doesn't for me as I would like to

  var StringVar="sample";
  
  
  
  
  myButton.addEventListener(MouseEvent.CLICK, function(e:MouseEvent){ myClickReaction(e, StringVar) },false, 0, true);
  
  function myClickReaction (e:MouseEvent, StrVar:String):void{
  
  StrVar="other sample";
  }
  
  trace(StringVar); /* it also gives me "sample" value and i would get "other sample" value */ 
  

  How to do it correctly?

  I do not know the structure of your screen lists so I can't tell you how to access the variable, but you're on the right track. If it's a parent, then you can always use the .parent property to cross to the top the list display to try to access.

  for example 1 level:

  MovieClip (this.parent). StringVar = "another sample";

  Add more properties .parent to continue to move to the top of the list.

  for example:

  MovieClip (this.parent.parent). StringVar = "another sample";

  Just like always, use traces (MovieClip (this.parent). StringVar); until you get the value that you want to know that you're accessing them correctly.

  I started my answer a long time ago while waiting for a reboot and am just finally getting back to it.  I see that you got another another answer in the meantime.  On the outbreak of reference, here is another link that might help some: Acq suite w / Ref Trig

  I did have not tinkered with reference trigger a lot, so not sure what is meant in the link above about the task being an acquisition over 'the end'.  Maybe the task continues to fill the buffer just before there about to overwrite the first sample of pre-trigger?

  In any case, my original thought the whole thing was on another track.  If the trigger Ref works for you, it'll be easier.   But if Ref trigger causes the acquisition of stop * and * you really need to keep it going permanently, then consider the things below:

  -------------------------------------------------------------------------------------------

  Passage of the continuous sampling done will require the judgment and the reprogramming of your task, and you will have a 'blind spot' of data loss, while what is happening.

  An approach that I think is to stick to a sampling WAS continuous, but also set up a counter task that can count it HAVE examples of clock and capture on the trigger signal.  The captured value of count will be HAVE it taste # when the trigger has occurred, and then easily post-process you your data HAVE to find the subset that represents your data before and after the desired trigger.

• Get the value of the question page before submitting.

  Hello all, I use the Application Express 4.2.5.00.08. I have a question on getting a value for a page element before the page is sent. I have a dynamic action:

  Action: Moving the mouse (on a region/State)

  Real Action: $('a[href*="39"]').each (function (index) {}
  lnk = $(this) .attr ('href');
  $(this) .parent)
  . Parent ('tr')
  .Attr ("href data ', lnk")
  {.mouseover (function ()}
  $(this) .css ("cursor", "pointer");
  Lrowrequired var = $(this) .closest ("tr"),.
  BLOCK = lRow.find("td[headers=BLOCK]").text ();
  $x('P39_BLOCK').value = BLOCK;
  })
  {.mouseleave (function ()}
  $(this) .css ('cursor', 'default');
  })
  });

  I am successfully able to get the value of the line while I'm hovering above the report (and P39_BLOCK is refreshing). But, in this case, the value is not set whenever it changes. My question is, if I need to use this value (say, put an another page element when P39_BLOCK is changed) without submitting the page, how is that possible?

  Kind regards
  MFadel.

  Hi Mohamed,

  That's what bothers! In my first dynamic action, I have real action 'Execute JavaScript Code', which doesn't have a property "Page items to show.". And I need this code to retrieve values from the row of the report.

  On the right, you will have the option 'page elements to present' the dynamic JavaScript actions. Only the PL/SQL. And you do not need to handle things strictly the use of javascript. JavaScript is usually used to manipulate items on the page itself, not the things on the server/session). If you need to present before your PL/SQL block, you can either use AJAX call, or you can create a dynamic action of PL/SQL that runs before your JavaScript. Put this field in the 'submit' page elements and the block of code, just put null;

  Here's a sample in javascript, ajax call. It pushes three elements of the page in the session or in the scope where APEX can access their values. You can return values through AJAX if necessary also:

  $.ajax ({type: 'POST',})

  URL: "wwv_flow.show",

  data: {}

  p_flow_id: $('#pFlowId').val (),.

  p_flow_step_id: page,.

  p_instance: $('#pInstance').val (),.

  "x 01': P39_PAGE_ITEM_1, '.

  "x 02': P39_PAGE_ITEM_2, '.

  "x 03': P39_PAGE_ITEM_3, '.

  p_request: 'APPLICATION_PROCESS = YOUR_PROCESS_NAME'

  },

  success: function (data) {}

  Console.log (Data);

  }

  });

  Then you would have a PL/SQL process called YOUR_PROCESS_NAME that can refer to variables such as

  my_var_1 VARCHAR2 (100 CHAR): = APEX_APPLICATION. G_X01; -Javascript password

  my_var_2 VARCHAR2 (100 CHAR): = APEX_APPLICATION. G_X02; -Javascript password

  my_var_3 VARCHAR2 (4000 TANK): = APEX_APPLICATION. G_X03; -Javascript password

  Can I use in my "PL/SQL procedure? Because in the end, I'm trying to use this value in a PL/SQL procedure:

  To answer your last question, Yes, you can use the P39_BLOCK in your PL/SQL, how you demonstrated above, but you must submit in the 'page' referred to submit box, otherwise it uses the last value that has been submitted.

  What I'm not clear, is do you need really value before executing the PL/SQL or you just want your PL/SQL? If you just try to pass it in PL/SQL and then just use the dynamic action of PL/SQL and pass it by using the "elements of the page to present. '' Remember, if you need a new value to publish on the page, you will need to put these fields in the box "items to display the page.

  If you only need the value of front page because you will use in javascript, somewhere, then reference it with jQuery or js and then use AJAX to continue your treatment.

  A third way, you could do, is to create a dynamic action of PL/SQL that runs before the javascript code that is null; in the body of PL/SQL, but put the P39_BLOCK in the "elements of page to submit" box. Who will just send the page element, and then take action dynamic javascript. But, I don't know why you would do that since you can't have the value submitted for javascript to use.

  Hope that all makes sense.

• Method = GET CFFORM behaves differently in CFMX6.1 in CF 8?

  Hello world

  My organization is testing applications for a move to CF8 CFMX6.1, however, we found there seems to be a difference between the way CFMX6.1 and CF8 run the GET method in a CFFORM Tag.

  I'm not sure why our developers have used the 'GET' instead of 'POST' at first. In the application, I'm testing, I found that all but one of the 50 + occurrences of 'GET' can be changed to 'POST' without problem. However, I worry a bit with many other apps we have and the amount of testing that would be required.

  Here's what happens:

  CFMX6.1: an added query string parameter is always part of the submitted url ACTION to either POST or GET.

  CF 8 : A query string parameter that is appended to a url in the ACTION attribute will be part of the url submitted when the METHOD is POST, but not when the METHOD is GET.

  To see the above difference, run the sample code below both CFMX6.1 and CF8. When running in CFMX6.1, you will notice that when the NEXT button, the myTestParameter = 123 parameter is present in the browser's address bar and the variable will be accessible in the resulting page. This will not be the case when running in CF8

  < h3 > Test CFFORM POST vs GET (CFMX6.1 vs FC 8) < / h3 >
  < cfoutput >
  < table >
  "< cfform method ="get"action="/Bayerah/gettest.cfm?myTestParameter=123 ">
  < input type = "hidden" name = "mytestFormVariable" value = "abc" >
  < b >
  < td >
  The CFform tag that displays this text contains action = '#CGI. Path_Info #? myTestParameter = 123 "
  < br / > < br / >
  < strong > CF 8 < facilities > < br / >
  < p >
  The query string parameter 'myTestParameter = 123' will be part of the url when the
  METHOD is POST and the form is submitted, but not when the METHOD is GET
  < /p >
  < br / >
  CFMX6.1 < strong > < / strong > < br / >
  < p >
  The query string parameter "myTestParameter" is displayed with the POST and GET
  < /p >
  < br / > < br / >
  Press "Next" to submit the form...
  < table >
  < /tr >
  < b >
  < td >
  < input type = "submit" value = "Next" >
  < table >
  < /tr >
  < / cfform >
  < /table >
  < / cfoutput >

  Thanks in advance.

  It doesn't have really anything to do with cfform.  The "method" attribute did not exist in MX6.1. So the generated html form code used method = "post".

  You will see the same behavior in MX6 if you create a simple html form with method = "get".

  [Edit] A better way to put that last comment is: that parameters in the action url must be respected when the form method is GET. My instinct is 'yes '.  But I don't remember what the rfc specifications will say on the subject.

• acquisition of continuous sample with multiple channels

  Hello! Please tell me what I'm doing wrong here, I'm confused about how the acquisition of continuous sample with several channels (using NI USB-6215 boxes).

  Following code is python code, but I don't know who confuse you (and it's only a part of my code in order to not try, it won't work

  buffer_size = 2000 #samples to read
  sampling_rate_hz = 20000
  channels = "Dev1/ai0 ai1/Dev1" #this can be a string or a large number...

  CHK (nidaq. DAQmxCreateTask ("", ctypes.byref (taskHandle)))

  CHK (nidaq. DAQmxCreateAIVoltageChan (taskHandle, channels,"", DAQmx_Val_Cfg_Default, float64(-10.0), float64 (10.0), DAQmx_Val_Volts, None "))

  CHK (nidaq. DAQmxCfgSampClkTiming (taskHandle,"", float64 (sampling_rate_hz), DAQmx_Val_Rising, DAQmx_Val_ContSamps, uInt64 (buffer_size) "))

  CHK (nidaq. DAQmxRegisterEveryNSamplesEvent (taskHandle, DAQmx_Val_Acquired_Into_Buffer, uInt32 (1000), uInt32 (0), EveryNCallback_func, None))

  CHK (nidaq. DAQmxRegisterDoneEvent (taskHandle, uInt32 (0), DoneCallback_func, None))

  the callback function #and

  def py_EveryNCallback_func (self, taskHandle, event_type, nSamples):
  data = numpy.zeros ((self.channel_amount,buffer_size,), dtype = numpy.float64)
  read = int32()
  CHK (nidaq. DAQmxReadAnalogF64 (taskHandle, buffer_size, float64 (10.0), DAQmx_Val_GroupByScanNumber, data.ctypes.data, buffer_size * number_of_channels, ctypes.byref (read), None))

  With only one channel, everything's fine, and tension diagram looks like this:

  

  buffer_size = 2000, sampling_rate_hz = 20000

  But if I use two channels, voltage diagram looks like this

  

  buffer_size = 2000, sampling_rate_hz = 20000

  It looks like the sampling rate is higher or there are fewer values?, but with two channels with the results table is 2000 * 2 long and with a single result is 2000 * 1 long is not smaller

  most of the settings important (?) in my code:

  DAQmxCfgSampClkTiming "float64 rate": 20000 (sampling_rate_hz)
  'UInt64 sampsPerChanToAcquire' DAQmxCfgSampClkTiming: 2000 (buffer_size)
  DAQmxRegisterEveryNSamplesEvent "uInt32 nSamples": 1000 (?)
  'Int32 numSampsPerChan' DAQmxReadAnalogF64: 2000 (buffer_size)
  DAQmxReadAnalogF64 "float64 [] readArray": [[buffer_size] * number_of_channels]
  'UInt32 arraySizeInSamps' DAQmxReadAnalogF64: buffer_size * number_of_channels

  as you can see nSamples is a big question mark, but the problem still exists if I set variable buffer_size y (2000)

  Hi Dazzler,

  It is not a multi-channel example that ships with the driver, but after a quick look at the code that you use in your third post, everything seems to be configured correctly. The only thing I was thing I got a question about your plots. Looks like you draw each time the same number of points. If you draw just the table of data directly from the playback feature, you need to draw (buffer_size * number_of_channels) number of channels since the data returned is as an interlaced array. You can also choose to deinterleave samples. More information about this lie in the NOR-DAQmx C reference help, which is installed with the NOR-DAQmx driver.

  Kind regards

• Get the value of point of contact OFA

  Hi guys,.

  I am new to oaf, so this may seem like a very novice question. I tried several things, but could not solve it.

  There is an advancedtable region in my page. The first column of the advanced table has been put to contain elements of binding while the rest of the columns are messagestyledtext. The advancedtable would be filled with a few details of the item with the first column is the item number. The requirement is to fill in the details of article on click in the item number which essentially appear as hyperlinks.

  I try to get the number of the first column.

  pageContext.getParameter ("itemnumber");    ['itemnumber' is the ID of the binding inside the column inside the advancedtable element]

  This returns null, so I can't get the item number. Can someone please help me solve this?

  Thank you

  Sasmas

  You can see the bottom of thread for "the line being returned as null Reference".

  https://community.Oracle.com/thread/581600

  As an alternative, you can add parameters, p_item_num to the PPR method with value in the form ${oa.current.ItemNumber} (if the number represents the VO attribute name)

  In the processFormRequest, get the value using "pageContext.getParameter ("p_item_num")"

  Therefore, the code will be

   public void processFormRequest(OAPageContext pageContext,
                                     OAWebBean webBean) {
          super.processFormRequest(pageContext, webBean);
          OAApplicationModule am = pageContext.getApplicationModule(webBean);
          String event = pageContext.getParameter("event");
          if ("itemLinkClicked").equals(event)) {
          {
                 String itemNumber = pageContext.getParameter("p_item_num");
  
                  Serializable[] parameters = { itemNumber };
                  am.invokeMethod("fetchItemDetails", parameters);  
  
          }
      }

  I have four 'levels' portfolio and ideally, I would like to have a user select a year in the high parent page and have it spread down to the forms under.  I went as far only to create a category for all portfolios that accesses the value of parents above him.  Once on the level of form, I am unable to get this value.  I guess that the getHomePortfolio method does not once on the level of form, but I don't know.

  Unfortunately it doesn't seem to be the documentation with examples on how to use the functions at all so I'm poking around in hopes of understanding how everything fits together.  Unfortunately, I was in it for a year without any chance to find the most of.

  Does anyone have information on how I can create a global variable that is accessible from any level?

  Thank you.

  No, just another way to get the desired response. Probably you won't need the audit NaN since your RegEx is specific enough that it will return only an index for any string of 2000-20 to 2099-20.

  I suspect that you will need a text category for each position of FY you need year and add the "FY" + starting value of the year.

  V/r,
