FPGA open file reference difference calling bitstream or VI?

• dynamically called vi, PDM invalid file reference

  Hello

  I can't explain a strange behavior, I hope someone can give me a hint.

  First of all, do not ask why I need this way to go, I would like to understand why this is happening.

  We have a FGV which has 3 actions: Init, write data and close. It works on the TDMS files. The action of the init creates a TDMS file reference that is stored in a shift register to be prepared, used by writing and finally narrow cases.

  Everything is OK, if I use this FGV simply in a main VI directly from the block diagram. So that I can init, write data and finally close the PDM file.

  However, for some reason, appeared a new requirement: to be able to 'Init' and 'Close' the TDMS file using the FGV, but within a dynamically called VI (a pop-up window that may not stop the execution of the appellant).

  So in primary VI, I call dynamically VI one another by using the asynchronous call (flag x 80, "call and forget" method), and it dynamically called VI fires the FGV TDMS.

  When I probe the reference of TDMS files, I can see that it gets its value correctly after the case 'Init' of fire. After this 'init' which happened (from Dynamics called VI), a location in the MAIN VI starts calling this FGV with enum action 'Write '. I can see via sensors, the case of writing Gets the same number of REF TDMS file which has been stored in the shift register after the case 'Init '.

  But even so, the VERY first function TDMS write throws an error msg "TDMS file invalid reference '! How is it possible, if the file reference is OK and the same as that created by the function 'File open TDMS' in case 'init '?

  Again, if I execute 'init' action also directly the main VI, not a third dynamically called VI, everything is OK, it works.

  I hope that my explanation is not too bad

  Thanks for the tips and if no idea, I'll try to recreate/replicate this behavior in a test project that is small, and I'll post it...

  The problem is that when the dynamic called vi stops all references that he open invalid.

  To see what I want to say, change the dynamics vi delay like 30 seconds before she stops, the savings loop works fine until the dynamics vi stops, then the error returns.

• The file reference does not call. upload()

  OK it's going to take a little bit to explain but stick with me:
  
  I have two layers in the timeline, with no keyframes (coucheUn) and the other with a picture any key for every frame in the layer (layerB).
  In coucheUn, I have the script action to declare a variable of FileReference and I also declare and attach a listener object to the file reference.
  The listener object detects the event .onSelect to the FileRefernce (this event is generated when the service. the FileReference class's browse() is called - which opens a file browser and allows you to select a file). When called onSelect listener object executes the function. upload() FileReference which analyzes the file selected to a php script that downloads the file on my server.
  Function. for the FileReference browse() is called from an image in layerB. This is where the weird stuff that happens.
  When I test the movie the first time I enter the keyframe that calls the function. browse() all download routine work and the file is downloaded successfully. If I continue to the next keyframe (using navigation controls) and then navigate back and try to repeat the download process, then the file browser opens successfully, I select the file and then nothing happens. I have problems to identify the problem, for as far as I see it is as if it does never emit the onSelect event once the file is selected, which shouldn't be the case that the function .Browse works and a file is selected successfully. This would imply the php script does not work which is just ridiculous because it is a very simple script and it works the first time.
  Everyone has ideas, if you need more just information!
  
  
  UPDATE:
  
  Just did some tests and I'm completely confused, it's something the onSelect event. For some reason, it is not called / is not detected by the listener object. It's just weird because he calls good the first time you enter the frame, but if you navigate back, it is not detected. I checked the listener object was still in the scope of this framework and it seems to be, so I'm completely confused. The listener object is there and listening, the event that generated the onSelect event is executed but then never detected.

  Wooops, corrected just, said an another FileReference var on the following image with the same name, changed the name and works very well. Really really stupid of me.

• ("VMError when calling code Connector.open("file:///c: ") (and a few other formats)

  Hello all, thanks for reading this question. I'll start with the problem. I wouldn't actually call the Connector.open with "file:///c:" as an argument for the real program. I've just simplified to do later when it did not work to try to find the problem.

  Data sheet:

  JDE4.5

  Using components package 4.5 Eclipse plug-in

  Running in from Release or Debug in the Blackberry Simulator

  Code:

  ("To debug in my code it rolls up to what I touched the Connector.open("file:///c line: ") I also tried these formats.

  Connector.Open("file:///c:/"); "

  Connector.Open("file:\\\c:\\") "

  ("Connector.Open("file:\\\c: ")

  originally it was-

  Connector.Open("file:///c:/Caleb/middieFolder/") "

  I tried the same thing above formatting with this URL

  The problem:

  When I hit this line of code with one of the strings above as an argument it throws this exception

  Exception class - FileIOException

  Message:-e.getMessage () actually get an error also. net.rim.VMError - I get a message at the bottom of my Ctrl + Maj + I window - net.rim.vm.VMError calling toString.

  (This probably happens because it is null)

  _errorCode = 1003

  backtrace = null

  I guess for some reason any he just dislikes the URL I provided what is a good way to test this? can I call to C: if I'm testing this on my computer?

  Thanks for any help.

  ' c: / ' does not exist. You call the same path in the Simulator as you would on the device. Set the Simulator to simulate a SD card is inserted.

• Error-2501 TDMS invalid of the file reference

  Hello. I'm using LabVIEW 2013 for myRIO on Windows 7. Im trying to perform a simulation to the readings of sensors from 0 to 5, then disconnect the data. Ive used the random number generator to get readings. So my code works very well (or almost), as ive used reporting to stop several loops with a stop button. I put not too many timers. I'm using TDMS files to save data. Ive opened a common PDM file in which I want to connect 4 different reading groups. Im getting the error '-2501', 'invalid file reference '... How can I get rid of him? My VI is attached below.

  Thanks in advance

  Hello

  In your attachment VI, you wired 1 'TDMS open' with 4 'TDMS shut. " If none of the "TDMS Close" has been run, the other reference has become invalid 3. This is why you are having error-2501 and this is the expected behavior.

  In fact, 1 'TDMS open' should only be connected to 1 'close TDMS"and make sure that"Close TDMS"is called after all the PDM operation. You can put it in a 'flat sequence Structure"to solve the problem. I modified your VI in the attachment.

  Thank you.

• It is possible to pass arguments to a VI uses "Open VI reference.

  I am modifying pre-existing code. (I say this, because there are many other ways to work around this problem, but I'm stuck with what I have)

  I have a large project that is compiled into an EXE file.

  Within this project, it uses the 'Open VI reference' in VI that is bundled in the compiled exe file.

  All good, no?

  Well, here's the question:

  Is it possible to include arguments of open type of command line with a "reference VI"?

  Where I can say "Something.vi / Option: Foo".

  

  I tried many variants such as

  ' Something.vi-/ Option: Foo ".

  even tried variations such as

  "C:\MyLVProgram.exe\Something.vi Option:Foo".

  (Interestingly, quite there no error when you do "C:\MyLVProgram.exe\Something.vi" when executing the VI reference opened.)

  This exe is deployed in a system that has only installed the runtime.

  My current environment is LV 8.6.1. (I know it's old)

  It seems that the antiderivative of LabVIEW recognizes only the paths, and in all other cases, I get an error

  Error 1026 to invoke the node in Something.vi-> MakeSomething.vi

  Possible reasons:

  LabVIEW: VI Reference is not valid.

  Any ideas?

  You can only send command line arguments to an executable with the system Exec.  If you want to pass data in VI, then use the asynchronous call with run.

• Tecra M7: Vista 'Open file security warning' for Alptec pointing device .exe files

  I gritted my teeth and updated my M7 for Vista Ultimate Friday. Overall I am very happy with the results. I have stripped the machine of all Toshiba drivers before installation and then re-installed all Vista drivers afterwards.

  Everything seems to be OK aside, whenever I boot, I get the following errors when the device pointing Alptec drivers load: open file security warning - the Publisher could not be verified.
  Are you sure you want to run this program? The file is: C:\Porgram Files\Apoint2k\appoint.exe, then the same thing for: c:\Popram Files\Apoint2K\ApmsgFWD.exe and C:\Program Files\Apntex.exe. I click "Run" on each of the applications and uncheck the button "always Me ask."

  It makes no difference and every time that I reboot, I get the same error. If anyone has had this problem, and if so, do you know how to fix it?

  I suspect it is a problem of certificate with Alps Electric Co Ltd and have checked their website and found nothing.

  Help much appreciated as always.

  Hello

  Just a question before we start any discussion here: have you downloaded and installed the drivers, tools and utilities for Toshiba download page in order facilities listed in the instructions facilities document?

  BTW: where you have downloaded the pointing device Alptec driver?

• Definition of registry FPGA: using the reference transmission

  Question of Labview FPGA basis. When I use FPGA read/write control to set a record in an FPGA, is there a difference between using a FPGA reference 'place' (connection FPGA VI reference Out on a block from the FPGA VI in the next reference) or directly to sharing the same node of reference?  Image below illustrates the two spare connectors: they are functionally identical? If so, why is there an outside reference? Is it just to keep the more neat wiring diagram?

  

  Yes, these two are the same, they would be for any reference type in LabVIEW. The top version is much more clean, however, isn't? Also, if for some reason you do not want to use error wire, wire reference here provides another way to enforce the order of execution.

  Also note that you can drag down the node to read/write to read and write several items in a single node, and they can be a mix of reading and writing.

• set the configuration of appeal vi for node reference vi call

  As noted in the title someone knows how to set the configuration of appeal vi (load with the appellants, charging for each call, load and store on first convocation) for a vi dynamically loaded via call by reference node?

  Thank you.

  CBR is irrelevant in the present case, since he already receives a VI reference.

  If you use the primitive opening VI refers to open this reference, then the VI will be charged the first time you call the primitive.

  If the VI leaves no memory (and you do not configure it on the way home), subsequent calls to the prim OVR returns the reference to the first VI you have opened. This is equivalent to the load and keep it.

  If you close and reopen the VI reference, it is equivalent to recharge.

  If you use a static reference to the VI, it is equivalent to the load with the appellants.

  Personally, I have all my default subVIs charge with the appellants.

• Open a reference to a labview project

  I am trying to automate a database containing information on all of our bunch of labview code ancient user. I need to determine what version of labview has been used, then collect information about the screws that are part of this. I don't find a way to open a reference to a project?

  I had almost closed the window when I happened to watch again invoke the mode that made me the 'VI' Version in VI files. And it was there, under the path of the project. So simple. I must owe marewa more. Have a nice day together.

• Open VI reference Cant find control

  Unless...

  From the beginning, I'm under LV2009. I open a reference to a global functional VI running on a remote computer to get the value that is in its "front panel indicator. I have two problems. The first is that when I use a string containing the name of VI, he will not find the VI. When I use the full path to the VI, the reference open VI works fine. Boring, but doable, because I have only about six FG read and they are all saved in the same folder.

  Second problem and the real reason for the post: I can get all the values of control as a variants without problem using Ctrl Val. Get all the method. But when I try to name a control in the method (Ctrl Val. (Get), I get an error indicating that the control cannot be found.

  SO, I used nodes property to get the text of the label and checked to see if everything was equal to the name of the command, I'm reading. It came negative. So I created a list of the labels out of the label. Property of text and node is the name I just checked for. So I copy and paste this back into the constant that is connected to the entry of the name of the control on the Val Ctrl. download Invoke node and no mistake. What the? So I delete the text I pasted in the constant and fix it and it still works very well.

  I checked and rechecked enough to know that I was not typing the name in wrong, but now it works fine. I can close the VI and reopen it, works very well. Type the name again. Still works fine. Any thoughts?

  An area located to the right of your constant original fits this description of the problem.

  May be useful...

  If you know the data type of the data that you read using the prpererty val node, you can use the node "to THE more specific" to set up your to the appropriate type. After that your val will not be a Variant, and you can use the standard LV operators to work with the data.
