• How to pass the session IMAQ to the Subvi

  Hello

  My experience with LabView is neither very good nor extended. I am a scientist and I'm with IMAQ data acquisition. My current problem is that the people who wrote the script is modular, versatile, or clear initially structured. So I try to reduce the ridiculous number of tests in a simple flowchart to a level that people can actually understand it... and to make the more versatile script for future experiments.

  I'm introducing quite a few subVIs to be executed repeatedly. However, I can't know how to pass the IMAQ session on the Subvi. I constantly get the error messages. In this case, I want to acquire images with OIDE_CollectFrame.vi controlled by OIDE_TrialPhaseCollect.vi. I couldn't understand how to assign the refnum IMAQ session class, either.

  It is probably a newbie question, but usually I program with LabView.

• How to pass a sequence of 'help' to run immediately

  How can I place a sequence.nxlval as a parameter using, here is my code looks like
  
  sql_string is-> insert into some_tab (col1, col2,...) (select col1: passed_seq,...) where the... (I want to insert values in sequence for col2)
  
  
  and I call it like
  
  
  passed_seq: = "seq_". some_dynamic_num |'. nextval' (in my PB will be sequences with the string formed as seq_10.nextval)
  
  EXECUTE IMMEDIATE sql_string using passes_seq;
  
  If I do like this I get
  
  Error: - 1722:ORA - 01722: invalid number seq_10.nextval

  So is there another way to solve my problem, where queries are already formed and stored in a table in the form of data in the column, and I need to run those from different sequences in different scenarios.
  >
  Yes - you change applications to use a placeholder for the sequence you need (e.g. [SEQ_GOES_HERE]) when you need to run it you create a PL/SQL block into a VARCHAR2 variable, then use run immediately on the variable.

  If your stored query would look like this

  sql_string is -> insert into some_tab (col1,col2, ....) (select col1,[SEQ_GOES_HERE],......) where .... 
  

  Load the good seq.nextval in a variable, and then replace "[SEQ_GOES_HERE]" in the query with this value.

• How to create session refnum imaq?

  Hello all,.

  I have an app where I would like to pass a Session IMAQ by refnum Sub several screws, however, I am unable to find all the information on the creation of Session IMAQ refnums. I saw it was in a previous post to an old version of labview, but can't seem to duplicate (the example http://forums.ni.com/t5/Machine-Vision/how-to-pass-IMAQ-session-to-subVI/td-p/2089804 snapvi)

  I use LV2013 and I have the VDM 2013 installed with all options (and be used at other functions imaq, so I don't think its an installation problem)

  I tried looking in the following locations:

  Controls palette (Refnum or under the controls-> range of Vision).

  Rapid decline (the research of refnum imaq or session)

  Assembly of the control and the indicator IMAQ Session (right-click menu)

  Hoping someone could point me in the right direction.

  Thank you

  If you go to any VI IMAQ, who holds the refnum and right-click on the entry of the session, you can select "Create control" and it will create one for you.

• How to change the sequence of films in iMovie Theater

  By exporting iMovie projects in iMovie Theater, the sequence of films is determined by the time of download. How to change the sequence of films in iMovie Theater list?

  HI, breeaz,

  I have not found a way to change the sequence of films shown in the movie screen.

  If you access your movies in the Finder folder, then Ctrl-click on the folder of the theatre, you will find your movies to the poster

  in the alphabetical order in archival records.   I was not able to manually rearrange it.   They can be rearranged in some categories, through the view menu item at the top of the screen and the changes applied to the entire window, but it was not carrying at the display of iMovie.  In General, I'd like to make changes to the structure of iMovie in the finder.  It can cause serious problems.

• How to pass a string to a vi from a dll?

  I have a DLL that generates errors in the log. How can I display my Panel before these errors? In other words, how to pass a string from a DLL to a vi using the library to call feature?

  Thank you

  Diego

  The DLL actually allocates memory for the string? If this is the case, there should be another function to free the memory. Otherwise you won't be able to do the deallocation of LabVIEW, which means you would have to write a wrapper DLL. If you do not have the deallocation, then you will have a memory leak.

  Are you sure that the DLL is not simply wait for a buffer "of a proper size? In this case, you can simply create a U8 in LabVIEW to a size that is larger that the largest string that you expect to get.

• How to pass the Visa Resource Name parameter to labview dll in labwindows/cvi

  Hello world

  I build a dll of labview, the prototype is: double getchannelpower (double f, uintptr_t * VISAResourceName);

  I don't know how to go from VISAResourceName to this function.

  Is it related to the ViPSession paremeter in function viOpen(REES ViSession, rn ViRsrc, ViAccessMode am, ViUInt32 ti,ViPSession vi)?

  BRs,

  lotusky

  Hey, guys:

  I figured out how to pass the parameter.

  In labview, you must replace the control of visa with string control. In this way, the generated dll function at the entrance of the string type.

  I hope this will help others!

• How to pass data (more effective) autour

  Hello
  I wonder how to pass around large data around across the application.

  For example:
  1 data or data of my analog channels
  (I have a lot of screws that will process these data of waveform)
  Is it not wise to spend around analog continuous data?

  2. What if you want to process digital data?
  (I must treat these unique bits in several screws, for example,)
  security door bit, stop bit of emergency, must be treated as higher priority than screw
  input 1, selector, etc.).

  Or you have any suggestions, what type of data I should use. I have a
  global impression screw actually write these digital data in a file, then
  These files are passed around?

  3. is there a mechanism that pass around data in memory, NOT in the files?

  By far, the way the more effiecient to pass data autour is a thread.  If you are really worried about memory, then you must avoid the connection of the wire that he holds the large amount of data.  This could mean making your processes in series (one at a time) passing the data of one Subvi to another via the controls and indicators and the connector pane.

  You can use the method of file sequence, open the application Manager (then you just need to connect the path to the file)

• How to pass an argument of javascript to java extension

  Hello, I have an application running with a Java Extension.

  For the course of time, I only call some java extension methods (ScriptableFunction, but now, I have to pass the variable javascript (arguments) to the extension.

  I call a method with:

  // In: public final class MyCamera extends ScriptableFunction
  
  public Object getField(String name) {
  
      if (name.equals("getImage")) {
       return callGestorCamera.pushUICameraSnapshot();
      } 
  
      return new String("do nothing");
  }
  

  and javascript :

  function getImage() {
      var name = mycamera.camera.getImage;
      return name;
  }
  

  and run correctly.

  But now I have to pass one argument, as some URL, and I don't know how to do.

  I try to move the handful of Java class to Javascript, something like this:

  // In: public final class MyCamera extends ScriptableFunction
  
  public Object getField(String name) {
  
      if (name.equals("getImage")) {
       return callGestorCamera.pushUICameraSnapshot();
      } 
  
      if (name.equals("getObject")) {
       return callGestorCamera;
      }
  
      return new String("do nothing");
  }
  

  and javascript :

  function setUrl(url) {   var handle = mycamera.camera.getObject;        handle.setUrl(url);
  
      return true;}
  

  but is not running and try:

  mycamera.camera.getObject.setUrl(url);
  

  but does not work.

  What is the way?

  Thank you!

  I believe that the Extensions lab shows how to pass a parameter to a function... For example, he spends the duration of the vibration.
