While the loop and the passage of a string to a Subvi problem

• CFC - URi too long during the passage of text string to CFC

  I have a page that allows the user to save a large block of text which is held in a < div > tag to the database without reloading the page through cfajaxproxy and a cfc.
  
  When you click on 'save' a javascript function draws text of the div block and stores it in a javascript string, which is then passed into a cfc using cfajaxproxy as a parameter to the javascript function. (ie. functionName (theTextBlockString);). It works fine except if the text contained in the javascript string var gets too long and causes a URi too long message.
  
  Display of the request in firebug, that I see the cfc is called via a GET request, which causes all my input parameters that I placed in the service to be placed in a GET url string, so of course when it is a long block of text, only the URL query string is too long, and I get the message too long URI of the CFC.
  
  What I'm trying to understand, is how hell I can pass a large text string in the EFA without encountering this problem. Is there an alternative application method so that I can't use GET?
  
  Thank you in advance!

  I found the setHTTPMethod parameter used during initialization of a cfc to cfajaxproxy - you can change it to a POSITION which obviously solves the problem. Adobe, mark POST by default as AJaxCFC, CFAjax, etc.! Maybe theres some reason to have default GET, who knows...
  

• Reading from the sensor to LabView via rs232 or Subvi problem

  I'm quite new to LabView and not too experienced with instrument control so I was wondering if someone could help me to solve my problem?

  Currently, I'm using LabView 2011 and I'm trying to read pressure DualGauge of Pfeiffer (TPG 262) pressure sensor and display the readings of two pressure on LabView.  However, when I run my program, the pressure readings are not displayed - what is displayed are default 0.00 if same mBar pressure reading a reading of the display of the DualGauge probe.  To connect the sensor, I use a RS232 cable and have managed to find the device on my device manager, so I don't think that the connection is the problem (I've also seen the port appears in the Device Manager, when I connected the sensor via RS232 and USB in my computer).  I also use Subvi Pfeiffer in my code, and I suspect that the problem may be in there.

  Attached is my code and here are links to the manual of the DualGauge and the driver of the software LabView of Pfeiffer

  Double manual gauge - p. 23 and 68 are probably the only things related to the RS232 connection.

  You have not tested really do anything. Devices and MAX Manager displays only the com port that you added to the computer. It does nothing to verify that an instrument is truly connected. You might have the wrong settings of com or the wrong type of cable serial (null-modem is required). I suggest that you start with program such as hyperterminal, PuTTY or MAX and try something simple. It seems that you will receive an acknowledgement returned by the instrument when a correct command is received. Make sure that this simple step that happens.

• Change the values of the cluster in while loop and in the face at the same time

  Hello.

  I have a little problem in a test program, that I'm working on. I'll try to simplify as much as possible. I have a cluster control that contains two controls A and B. I want to:

  1. switch to update the value of the command A a while loop
  2. allow the user to change the value of the B control through the face, while the loop is running

  To change the value of order in the while loop, I first get the cluster control cluster, update the value of the control for a way to group by name and finally rewrite the cluster in the cluster control.

  The problem is that if the user changes the value of the B control while control that is in the middle of the update, the new value of B control is lost because it was read before updating in the face. Is there a way to get around this?

  Then they do not belong in the same cluster.  They are disconnected obviously enough that they do not go hand in hand.

  Where it can get really complicated, it is that you're talking about the user and code changing the same cluster.  It is very dangerous and very difficult to manage.  You might be able to get there with a driving force.  But walk slightly, my friend.

• complete the loop and get data

  I need to acquire the acquisition values of data every x seconds. Waiting in the loop of data acquisition is defined so that the next N samples are acquired after x seconds. Pressing stop the loop of consumer DAQ stops after the sec x which is connected to the wait function.

  1. how to stop the inner loop immediately when you press a stop?

  I also write acquired samples after doing some calculations on the samples.

  1. plan of sample of the queue to file consumer loop. Is there any other recommendations such as drop loop is not without samples? How many data can an expectation of the queue?

  Thank you.

  sonotk,

  You've missed the point. Rather than having a 5000 milliseconds of wait, use an expectation of 100 ms and count the number of times that you have been waiting for 100 ms.  When the count reaches 50, sample and start the count again.

  The counter is just in the shift register containing an integer. Inside the while loop you have a box structure. Test the shift count register to see if it is 50. If set to True, use the real case of the structure of the case. Inside, it's all in your loop except waiting and the logic of the judgment. In the case of false, you add 1 to the shift register and wait 100 ms.

  Looking at your picture code once again, it seems that the shift with TempData and VoltData regsiters are not necessary because you never use the data previous iteration on the left side.

  Make a simple VI with two loops and some expectations.  Run with execution highlighting market to see what is happening.  It is a good learning tool.

• How to set the limit function, means I want defined logic that when the value is between 0 to 0.3 loop and then stops.

  Hello

  I'm looking for the logic as the way to define the logic of upper limit and lower limit.

  Means that there is only one indicator of entry in which a user can enter any value, I want that when the user gives value between 0 and 0.3 for example while then loop will stop other wise, it will work on an ongoing basis.

  Please guide me.

  Thank you very much.

• RandomGen elements, case structure nothing if it's false, while the loop passes iterations, can not get the values in table outside the structure of the case

  Hello!

  I tried to build a trigger that triggers a true value each 1000 milliseconds (from the first real);

  which real command structure box to a value of the randomNrGen of the sample and place it in a table.

  but I would like to USE this table and I can't do this beacause I can not get out of the structure of the case.

  AND:

  the while loop ignores samples; If you run the vi and look at the speed at which the table fills, ypu notice it is not periodic: the first few items are inserted at 1 second interval, but then it jumps one;

  would it be because of the wait time 1ms?

  1. How can I create a structure that does this:

  If set to True, it samples a value from Genesis at random and places it in the table

  OTHERWISE, it does NOTHING, without zeros sent to the table just waiting for the next true and only the values sampled at True remain in the table?

  2. How can I stop it pop samples (multiples of 1000 in my case)?

  In conclusion: I need to be able to take samples on the sample generator and store them in an array of 3d in a zig - zag (1.jpg) way, but able to think about it, we need to go beyond these two questions.

  Please ignore the meter.

  Please help me!

  This did not omit all values and it works fine.

  Is it possible to get information in a case without making use of the large loop?

  My program will become very complex (I need to synchronize a magnetometer and a stepper motor to make a 3d map of the magnetic field of the magnet) and I want to do everything as simple as possible.

  If there is a way to get information about a case structure, other tnan using registers with shift on the big loop, and you know it, please show me.

  Thank you!

  You could also use a Feedback node, just keep it out of the structure of the case.

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

  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).

• While the loop Tunnel help

  I have a variable inside a while loop, that I want to access outside the loop, that is, in my VI, I have two indicators, one inside the loop and the other outside the loop.  The variable is incremented on each iteration.  However, I am not able to see this iteration of the loop.  I see that the last value of the variable.  Is there anyway for me to access the variable inside the loop as it is running.  In regards to my VI, is it possible for my indicator "inside" correspond to the indicator 'outside '?  Any help with this will be appreciated.  Thank you.

  Kind regards

  David

  Yes.  You must use a local variable of the 'Inside' indicator that writes to the indicator 'outside '.

  There are other ways to do so, such as pass the data via a queue or a notifier.

  The concepts of tunnels, flow of data, and that data is not available to that structure, it is finished, is all notions of LabVIEW.

• Open a local copy or move on the server, and then disconnect while the task is running until the end

  RNOS6 running on RNDU600 +.

  Looking to start a local copy or move of the large collection of files on the server, and then disconnect the PC while the task is running until the end. For example, to move a branch of several hundreds of GB of small files from one share to another, or copy them to a share.

  Seems to make my PC (in wireless) is inefficient as each file seems to have sent to the PC first, then return to the NAS.

  Is there a way of ordering on the NAS, so that it can continue the operation even if the PC is disconnected?
