• Session ends not with StructClear function

  Normally, if you want to delete a session we do with StructClear function. But I don't see that it does not end in a user session because the same CFID and CFTOKEN values exist once we've cleared a session. This means so that it is not really ends a session. right?. But if we are expiring these cookies (CFID and CFTOKEN) values then we can see new values for these cookie variables. Here force us coldfusion to new values for these variables cookie but actaually there neither expired nor onSessionEnd() handler has been invoked.

  So my question is how effectively ends the session. But it won't work if we use StructClear function because it erases a logical business identifier as reported in your business logic.

  Anyone have any ideas on that.

  Suppose that you set your session timeout to 2 minutes.

  When you visit the page, you start a new session, CF generates a CFID/CFToken and SENDS that back to you in response to your first request.

  When you visit a page before the session, your browser sends the CFID/CFToken with demand, CF sees this, check the this is a live session and does not issue you a new.

  If you wait 2 minutes of a session timeout, CF kills the session, but not FACT NOT to MESS with your Cookies.  It doesn't matter, because they are invalid anyway.

  When you make a request, you send the CFID/CFToken now old, CF sees that it is not correlated to a live Session and generates a new CFID/CFToken it sends to you now and you update the cookies with the new values.

  A session expires on the server is NOT because ColdFusion deletes the cookies from the user's browser.  It States only that "for this combination CFID/CFToken, the session no longer exists, so let me generate a NEW session for you and send you it is CFID/CFToken to correlate your visitor to the new SESSION scope.

  In the meantime the timeout and check your cookies should show the last cookies you had when you request.  Nothing new.

  In your onSessionEnd() method, it will BE the old values because when the session expires, this method gets a COPY of the scope SESSION and APPLICATION, (the SESSION just expired) and it's the old data CFID/CFToken.  CF performs as one might expect.  What you trying to do?  I think that the problem here is that you don't understand how work sessions.

  A SESSION that CF is when he takes a cookie CFIF/CFToken provided the user request and checks to see if it is valid.  If so, then all the variables stored in the SESSION scope are made available for the processing of this application.  These cookies act as a means of your browser, say who they are.  By default, Session values are stored in RAM.

  When you do not apply for an amount of time specified in the THIS.sessionTimeout value, CF mess with cookies on your computer.  He says simply.  "Hey, these variables that I wanted for the SESSION which was for CE CFID and CFToken THIS, well, delete them.  The session has expired.  The browser will not see anything different either until he makes another request.

  When you make a request, once again, your browser provides CF CFID and CFToken cookies, but this time CF says ' Hey, that the session has expired, so I'll make a new one for you (lights off the coast of the onSessionStart() method) and he referred to a new CFID and CFToken cookie to the user who now matches the new session.»  A session that will stay alive as long as the user makes requests in the specified time-out period.

  If you have deleted your cookies, the SESSION would still be ALIVE, but it would simply be inaccessible, and after the time-out value, SEE it would expire.  But if you have deleted your cookies, to present a request to the server, we're no. CFID/CFToken cookies sent, so CF would create a new session for you and will send you a new CFID/CFToken.

• export to spreadsheet - data 2 channels appear in alternation with loop of producer/consumer

  Hello

  I'm having trouble with the function "Export the waveform to the worksheet" - but it is not clear to me if the problem is with how I use the export feature or if I am wrong concatenating two waveforms of different modules of the series prior to export, or if my queue is wired incorrectly for producer-consumer loops.

  I use a hunts SMU-1073 with SMU-6361 and 4330 modules (tension and strain). I tried to change the example of the "entry analog cross synch" for use with a structure of producer-consumer (see VI below).

  The output of the worksheet contains a large part of the data in the string tension, followed by a smaller piece of data (with timestamp) strain, after which the alternate output data between data of tension and strain.

  Can anyone suggest where I could go wrong, or how I could solve this?

  Attachments do not work, so I'll try to post in an empty message directly after this post.

  Thank you

  Claire.

  That's what I thought.

  A number of wire.  -1 gives all the samples available in the buffer (which can be zero for some reason any).  A number will expect that there are many examples.  If the two readings can wait until they have both the amount of data requested.  This way, they will also have the same number of samples and be better aligned in the text file.

  Your loop will continue to run until you press stop or get an error.

• Can I use data value references with a functional overall?

  Can I use data value references with a functional global?  I am trying, but it causes problems:  I run the attached VI with "new DVR" selected.  Then I run it again with "return array" and I get the error 1556: "The reference is invalid. This error might occur because the reference has been deleted."  It seems to have forgotten the DVR, but I thought it should be stored in the shift register.
  
  Another odd thing:  In my VI, if I try to connect the wire shown in "something strange", then the type changes (from U16 array to DBL), i.e. it doesn't recognize the type referenced by the DVR.
  
  I want to pass a very large 4-dimensional array between parallel loops with a functional global.  To avoid memory problems, I want to use a DVR and in-place element structures.  If that's not allowed in Labview, I will try passing it through a user event or notifier.  Any problems with those alternatives?
  
  Thanks.
  

  I received a response from an engineer applications OR on this subject, and it seems that it is perhaps a problem with Labview.  They are working on it, so I'll go ahead and close this discussion.

  Thanks for the help,

• Error with the function "Open/create/overwrite file" with cancel button

  I have attached a very simple VI who embodies what I want to do with my function to open the file. I just want to stop the rest of my program (theoretically embedded in the Structure box) to run if the user deigns to do not to specify a file location.

  However, if you click on the button cancel an error is produced before the rest of the program is running. If ignore you the error and continue, the "canceled" properly true made variable and the Structure of business runs correctly. "" I just want to remove the error message given to me by LabVIEW.

  Any ideas on why or how?

  Read the help of LabVIEW on automatic error handling.

  In your case, you can just wire the output of cluster of error to the structure of your business.

  

• Using subset of table with loops

  I have a 2D (m * n) table and I want to look at a subset of this table (x * y). I am having some problems using the subset of the table by doing this. If I want to browse 'y' columns of items containers 'x', I thought I could use a loop with the function of the subset of the array for interior but the resulting table I receive is actually a populated by the diagonal elements of my natal chart. I enclose my current VI where I hope that things.

  For example, if I load an image that is 800px * 600px then my program creates an array of 800 * 600 and each element is the maximum of the value of red, green and blue pixel. So, I want to watch the first 320px * 600px (which is a subset of the array with size 320 * 600). So, how can I use subset table properly to generate that 2d hack? My goal after this step would be to perfom some basic mathematical calculations like averaging on the subset.

• Can join us variable liquids with other variables or/strings of data in the declarations of liquids

  Can join us liquid variable with other channels for use in conditions or other liquid or variable methods?

  For an example simple Assembly variable/data with a string:

  {% assign newVar = globals.get.id + "#anchor" %}

  to get the result:

  newVar = / page-name #anchor

  or two variables in a conditional Assembly:

  {% assign var1 = "xy" %}

  {% assign var2 = 'z' %}

  {% If xyz is var1 + var2 %}     (but not + as in addition to math, actually join the 2 resulting from the chains of var1 and var2)

  so the if statement would be true.

  You don't need to capture Robert

  Adam,

  First is the sign + - in a liquid, it is 'more '.

  {{500 | more: 20}}

  And combine a string:

  {% assign var1 = "xy" %}

  {% assign var2 = 'z' %}

  {% assign combine = var2 | append: var1 %}}

  {{combine}}

  Capture is a double pass less effective.

• IsDefined dislikes the names of variables beginning with a number. Unless they are defined...

  Hello

  I detected a strange (for me) behavior of the IsDefined function. I have something like:

  < cfif IsDefined ("url.vose") > < cfset = "value" unevariable > < / cfif >

  < cfif IsDefined ("url.3d") > < cfset = "value" unevariable > < / cfif >

  * If url.3d is set, all right. All work as expected.

  * If url.3d is not defined, CF throws an error "Parameter 1 of function IsDefined, which is now url.3d, must be a syntactically valid variable name".

  * If I use structKeyExists (url, "3d") instead of IsDefined("url,3d"), works as expected.

  I have tried different combinations of variable names and extended (EP, url.5d, or form.3d) and the problem seems to be the number at the beginning of the name of the variable.

  This is the expected behavior? I found it very strange that it works if the variable exists and only generates an error if not. Can it be considered a bug and should be reported?

  TIA,

  It doesn't matter if the language is CF or JavaScript or PHP-HTML - variable names are considered invalid if they do not begin with a letter or underscore.  You must friezer prefix a variable name with a number.

  Also, I have heard many developers complain IsDefined().  Use rather StructKeyExists().

• Definition of session the names of variables based on variables in a loop

  I'm trying to set up a loop that puts in place a list of variables based on a loop on the list list, and setting the session.NAME:

  < list CFLOOP = "' #fieldnames # ' index 'fieldname' = >"

  < cfset session. #fieldname # = "1" >

  < / CFLOOP >

  He doesn't seem to like the session. A_CF_VARIABLE. then session. #fieldname # does not work, I get an error

  A CFML variable name cannot end with a '. ' character.

  The session variable. ends with a '. ' character. You must provide a key of the additional structure or remove the "." character.

  Do I have to wrap it another way?

  Thank you

  Mark

  You were writing, I had the scope bad format, I managed to strike up a little test that worked. I just needed to use the form [fieldname]

  What I noticed is that I used 1_email for the name of the form, when I came to hardcode for testing purposes, a CFSET failed, saying that this was not a valid name, so I'll have to change the format of email_1 etc, not much. Here's how I managed to make it work

  #session.email_1 #.

  Thanks a lot (again) for you help!

  Help, please

  THX pavel

  When a while loop, and the beginning of the loop for, they are running from end to end before anything else happens.  so, it's a problem.  You also have an inconsistency of the left and right bracket.  then things get worse with nested functions and a timer that don't do anything useful.

  I don't see any way to correct your code.  but here's how I would do what you want:

  var c:SoundChannel;

  var t:Timer = new Timer (2000,1);
  t.addEventListener (TimerEvent.TIMER, playF);

  var s:Sound = new YourSound();

  playF (null);

  function f (e: Event) {}
  t.Start ();
  }

  function playF(e:Event):void {}
  c = s.play (0.2);
  c.addEventListener (Event.SOUND_COMPLETE, f);
  }

• in combination with the function sequence

  Hello
  
  I have a problem with a sequence in combination with a function.
  
  I want to generate a kind of a hardware inventory report that contains some kind of a hardware ID (a number not repetitive, auto-increment, allowed deviations). However, I have to keep track of what material ID I used to which material of the inventory, for reasons of traceability. Another important requirement is that whenever the report is run, that the returned hardware IDs are never repeated. If repeatedly runs for the same hardware in the inventory must always return new material ID.
  
  So I was about to create a simple function from PL/SQL where I spend my data of traceability as parameters. Then the function uses internally a sequence (nextval) to generate a new hardware ID, then stores the new ID of material by related values in the input in a table (autonomous transaction) parameters and returns the new ID.
  
  It works pretty well so far.
  
  Now the tricky part: I want where I want to go back the same ID in different columns of a SQL statement.
  
  Let me give you an example:
  

  CREATE SEQUENCE XXX_TEST_SEQ
  MINVALUE 1 MAXVALUE 999999999999999999999999999
  INCREMENT BY 1 START WITH 1
  NOCACHE NOORDER NOCYCLE;
  
  
  CREATE PACKAGE XXX_TEST_PKG AUTHID CURRENT_USER AS
  FUNCTION get_id(p_someparameter NUMBER) RETURN NUMBER;
  END XXX_TEST_PKG;
  
  
  CREATE PACKAGE BODY XXX_TEST_PKG AS
  FUNCTION get_id(p_someparameter NUMBER) RETURN NUMBER IS
    l_new_id NUMBER;
  BEGIN
    SELECT XXX_TEST_SEQ.NEXTVAL
      INTO l_new_id
      FROM DUAL;
      /* do some more logic, e.g. store the freshly generated ID 
          together with the input parameter values in some tracing table */
    RETURN l_new_id;
  END get_id;
  END XXX_TEST_PKG;

  It is a simplified version of the function for demo.
  
  We will use:

  -- 1) this works as expected:
  select xxx_test_pkg.get_id(1) from dual;
  
  XXX_TEST_PKG.GET_ID(1) 
  ------------------------ 
  1                        
  
  
  -- 2) this returns two different numbers:
  select xxx_test_pkg.get_id(1) as id_one
      ,  xxx_test_pkg.get_id(1) as id_two
  from dual;
  
  ID_ONE                 ID_TWO                 
  ---------------------- ---------------------- 
  2                      3                      
  
  
  -- 3) This is the problematic case: I want to return the same ID two times:
  select my_id as id
       , my_id as same_id
   from (select xxx_test_pkg.get_id(1) as my_id from dual);
  
  ID                     SAME_ID                
  ---------------------- ---------------------- 
  4                      5                      
  
  
  -- 4) CURVAL on these sequence does not work:
  select my_id as id
       , xxx_test_seq.curval as same_id
   from (select xxx_test_pkg.get_id(1) as my_id from dual);
  
  SQL Error: ORA-00904: "XXX_TEST_SEQ"."CURVAL": invalid identifier
  
  
  -- 5) This gives the output that I need, but why?
  select my_id as id
       , xxx_test_seq.nextval as same_id
   from (select xxx_test_pkg.get_id(1) as my_id from dual);
   
  ID                     SAME_ID                
  ---------------------- ---------------------- 
  7                      7                      

  Query 3 is one who gives me headaches. I need to return the same ID in different columns. But it returns only two different pieces of identification. I know that the optimizer will merge the two select statements into one and therefore perform the function twice. Someone knows how can I avoid this?
  
  Which is a little strange to me, it's the query 5 is really what I need, but at first glance I would say that he should not do. I would say that using nextval would be me again another number sequence.
  
  It's confusing... Can someone explain this and advise how can I build a query if I can get the same ID twice by line?
  
  
  I know that I can totally get rid of the sequence in my function and use something different, but I was wondering if I can avoid to change my function.
  
  
  Thank you
  David.

  Oracle's FUSION query inline with the outer query block, which causes the function being called twice.

  Instead of MATERIALIZING suspicion, or relying on ROWNUM = 1 effect predicate aside, I would explicitly tell the optimizer to not do so via the NO_MERGE indicator.

  select my_id as id
       , my_id as same_id
  from (select /*+ NO_MERGE */ xxx_test_pkg.get_id(1) as my_id from dual);
  

• Update of Variables between two loops

  Hi all

  I use LabView to work and did not have formal training in it, so I'm learning I'll. The problem I'm having is LabView won't let you pass variables from one loop to the other let say update the entry, my understanding is probably wrong. In the code shown below, I need to be able to update the entry for the cycle of use based on the measured laser power. This program is ideally year a CO2 laser for any desired power by adjusting the cycle until the electricity meter is +-1 watt of power you want to be. This duty cycle can be used as input into another program to run the laser at a specific energy. Currently on duty cycle block diagram will adjust but its not really the entrance of the device changes. This is my LabView knowledge to short.

  Any ideas anyone?

  Thank you!

  
  

• Fitting with integral functions

  Hello

  I try to fit the data with full functions.  It is impossible to obtain analytical solutions of the integrations.

  Integration is integral [(T - abs [x]) f (x) dx, T, - T]

  Here, f (x) is one of the functions of autocorrelation for different model systems.

  Thank you

  Doogie

  Hi Doogie,

  We certainly have the integration and curve build VIs in LabVIEW. For example, you can find several kinds of system integrators in the mathematics > integration & differentiation palette. Also, if you use our design Simulation tools by & control, that built the integration as well. However, because you are dealing with an equation as opposed to sampled signals, I'd start by programming your equation in LabVIEW. Take a look at this forum thread that discusses this, and examples of code.

  Once you have programmed the equation and can generate an array of points for your stove, you might try to enter a function of integration as the "Integrate x (t) .vi" and then use a function as the "general polynomial Fit.vi" curve to generate an equation fitting for him. I would try getting started in this way. Please let me know if I address not the functionality that you are interested in.

  Best regards

• Kalonline-works until I get the anti-piracy icon so stop saying: there is a problem with the function of anti-hacking

  I play kalonline (RPG game), when to start the game it works up until I get the anti-piracy icon so stop saying: there is a problem with the function of anti-hacking. the program stops. I am the admin of it say kal computer run it in administrator mode and I did and I delete and reinstall the game. Solve the problem in win 7 by a right click and run as administrator, they wanted to work in win xp it all fits on how to solve this problem. These are the things, I was told to do to fix it.
  Hello

  It comes to KalOnline.

  Your error message can be corrected by following these steps:

  1. run KalOnline in Administrator Mode.

  2 uninstall KalOnline d_lete the entire Inixsoft folder, then reinstall the game.
  I did it and and it has not worked. then I was told that this was causing the problem

  Please check your computer system.

  This problem has occurred by a kind of problem of piracy.

  And if you have used a kind of memory-editing program, it could be happen too.

  So if your receipt similar to, then please remove it.
  I have none of these things on my computer. All I know is that people who have not updated windows xp can play the game and people who win 7 can play the game if they right click icon and run as administrator, that I still say side here but no way to prove it.

  Hello

  I suggest you to get in touch with the manufacturer of games and see if there are any other fix for this problem.
