How to use ctrl val.get on a Subvi running?

• CTRL val get reference returns zero refnum

  I use 'ctrl val get' in a vi.  The value it gets is a bunch of references, the references are returned with a value of zero.  Is there a prohibition against the use of 'ctrl val get' by references?

  Adde a probe earlier to see what Ref was not valid.

• Programatically register values of control only works with Ctrl Val.Get all (not recommended)

  Hello

  I just downloaded "programmatically save 86 vi of https://decibel.ni.com/content/docs/DOC-3551 control values.

  This works.  In the recording, but there an invoke with Ctrl Val.Get All (deprectated) node structure of the event.  I thought that I would get rid of the obsolete reselecting the control method get all.  Of course it was more an (outdated) at the end and the top of the page, little changed from pink to yellow.  However when I run and load a file that is saved I get: error 116 took place to Unflatten chain... Possible reasons:

  LabVIEW: Unflatten or stream of bytes read operation was in pain due to corrupted, unexpected or truncated data.

  A few questions:

  If I were writing this thing without having to download the example it wouldn't work.  Any ideas how I would work in LabVIEW 2011?

  The example is quite old, people would use another method of loading and storage of the parameters in a VI these days?

  This VI crashes after a while.  Is it because he has two event Structures in a loop or because there is no case of timeout or what? (I am not really concerned about why it crashes but if someone knows the answer without wasting time running it I'd appreciate it)

  Thanks for the tips, things that I can draw from this

  The old ways worked with a data type that was {name, type descriptor, flattened data}. The use of new methods {name, variant}, to adapt the code to work with this data type. Also, you cannot use the old data with the new code files.

  I'm assuming that the VI is lock because you have two structures of event in a loop simple (it would make sense, since each structure must wait for an event is to occur), but I'm not the code itself, I can't be sure.

  With respect to the other options, I generally without saving all the controls on a front panel, but when I want to record a bunch of controls, I usually use something like this, which can also work if you collect all the controls of the FP. There are also links to other similar things in the more 'like this' section with the page.

• Change Ctrl.Val.Get or binary write format of LV8.5 until 2014

  Hello

  I have recently updated from LV8.5 to 2014 and a problem of compatibility. I used the Crl.Val.Get method to get an array of values and save them in a binary file:

  

  to read later with a binary read:

  

  My problem is that the files generated in this way with LV2014 (64-bit) cannot be read by LV8.5 (32 bit) - the result is a "LabVIEW: Unflatten or stream of bytes read operation failed due to corrupted, unexpected or truncated data" error or an application crash.

  Writing binary VI changed of LV8.5 ro 2014? Is this a problem for 32/64-bit? Oddly enough LV2014 reads the files generated with LV8.5 without problem. Is it possible for me to this LV2014 program to ensure backward compatibility with LV8.5 (something that I need for a prolonged transition period).

  Kind regards

  Casper

  About, unless you set the binary file format exactly (for example define how you store the data in the file until the byte level) I'd be dubious on the file is readable in the new/old versions of LabVIEW - especially if you are using types of complex data as of the beams.

  Dealing with backward compatibility would be either define the binary file format and work to that or use a file format string in function (e.g., JSON, XML, INI) for which you can write a compatible rear parser. The OpenG library has screw for saving/loading of the controls in the Panel before a VI in an INI file, for example (even if OpenG stop supporting, it's a format string in function, so you can always write your own parser if you need to in the future). I know that don't helps you you in your current situation, but maybe something to keep in mind for the future.

• How to use JS to get the movieclip in the Web?

  Hello

  Look at this code example:

  JS of the canvas:

  (function (lib, img, cjs, ss) {
  var p; // shortcut to reference prototypes
  // library properties:
  lib.properties = {
  width: 550,
  height: 400,
  fps: 24,
  color: "#FFFFFF",
  opacity: 1.00,
  manifest: []
  };
  lib.ssMetadata = [];
  // symbols:
  (lib.mc = function(mode,startPosition,loop) {
  this.initialize(mode,startPosition,loop,{});
  // ss 1
  this.shape = new cjs.Shape();
  this.shape.graphics.f().s("#FFFFFF").ss(1,1,1).p("ApwmjIThAAIAANHIzhAAg");
  this.shape.setTransform(62.5,42);
  this.shape_1 = new cjs.Shape();
  this.shape_1.graphics.f("#FF0000").s().p("ApwGjIAAtGIThAAIAANGg");
  this.shape_1.setTransform(62.5,42);
  this.timeline.addTween(cjs.Tween.get({}).to({state:[{t:this.shape_1},{t:this.shape}]}).wait(1));
  }).prototype = p = new cjs.MovieClip();
  p.nominalBounds = new cjs.Rectangle(-1,-1,127,86);
  
  // stage content:
  (lib.mymc = function(mode,startPosition,loop) {
  this.initialize(mode,startPosition,loop,{});
  // mc
  this.mc = new lib.mc();
  this.mc.setTransform(215.5,167.1,1,1,0,0,0,62.5,42);
  this.timeline.addTween(cjs.Tween.get(this.mc).wait(1));
  }).prototype = p = new cjs.MovieClip();
  p.nominalBounds = new cjs.Rectangle(427.5,324.6,126,85);
  })(lib = lib||{}, images = images||{}, createjs = createjs||{}, ss = ss||{});
  var lib, images, createjs, ss;
  

  HTML:

  <body>
  <canvas id='canvas'></canvas>
  </body>
  <script>
  alert('lib.properties.fps')
  </script>
  

  My question:

  the canvas has a movieclip named "mc".

  How can I alert the 'mc' as alert the 'lib.properties.fps '?

  alert('lib.mymc')//success
  alert('lib.mc')//success,but it is library ,Not in the scene
  alert('lib.mymc.mc')//undefined,how do it?
  
  

  Thank you very much!!

• How to use the registration centres to stretch and run properly a MovieClip

  

  Is the type of an explanation of what I'm trying to do.

  I have 2 known points, a slope angle that I want to turn and the hypotenuse.

  I spent at least an hour to try different things and Google search.

  Any idea on what I should do? Currently a bit setting the greater width and then using .rotation.

  Thank you.

  use a reg top center point.  assign your circle x, match the top point x y.  then assign the width and the height to the distance between the two points and finally its rotation to the atan2 between two points of the circle:

  circle_mc.x = p1.x;

  circle_mc.y = p1.y;

  circle_mc. Width = circle_mc.height = Math.sqrt ((p2.y-p1.y) *(p2.y-p1.y) +(p2.x-p1.x) *(p2.x-p1.x));

  circle_mc. Rotation = - 90 + 180 * Math.atan2 (p2.y - p1.y, p2.x - p1.x) Math.PI;

• How can I update the driver for the webcam running Windows 98 > vista windows?

  Hello

  How could I go to get a driver who runs a
  Home QuickCam vs Webcam on my Windows Vista computer? I found the webcam in an old car for scrap, but the software is not compatible with my Vista. Pleassssse! help > I been up all night looking for the web and gettn dressing!  Thank you, Faye

  Get the manufacturer, the brand and model of the Webcam and go to the manufacturer's technical support group and see if they have Vista drivers available for download.  If they do not exist, I'm afraid you're out of luck. If available, download and install and you should be running.  But you should contact the manufacturer.  Given the age, it is very likely that there's no Vista drivers for this device.  There is no realistic way to do your own drivers, unless you are a developer of professional pilot (and even then, it would be not possible).

  I hope this helps.

  Good luck!

• need to know how to block the ophcrack from running, my child uses this to get my password and in the parental controls in vista

  you want to know how to block the ophcrack from running, my child uses this to get my password and in the parental controls in vista. I have 3 accounts going 2 for children and one for the parents/administrator. I found ophcrack in several places on the computer. any help would be greatly appreciated

  The only question the idea of Malkeleah, that is when you put a password on BIOS, all you need to do is pop the battery from the motherboard and the password is gone. Faronics has in some programs such as anti-executable and a few other programs that may block the name or ID of a process and prevent it from running (some antiviruses have that option, such as Avast, but usually is a pain in the ass to configure)

• I get request to update my Flash Player from Adobe. What is c? Where to find info on how to use it?

  I don't really know how to use this thing, I'm seriously "physically challenged and a slow-learner." and my computer repair man keeps changing computers about me.  (In this I am not sure that it helps me.  Once I have to get used to some programs, there are 'new '.   His "real confusion.  For example, I got a real easy to use-address book that had all my personal and business addresses and telephone #s in there.  The computer got a 'blue screen' several times, so he came and changed my "Dell XPS" computer professional with a 'new' (a ' Dell 7 Ultimate' it was 'better'.    If I could afford it, I buy a new one and start over) so I rarely know 'where' I am, or what to do when I'm 'where I am.  With a full-time job and a serious hobby of computer repair, it doesn't have the time to help me with "operational" issues This put an unfair burden on anyone trying to help me, but I HAD TO GET HELP - SOMEWHERE, so if I'm not a gene with what will be long-term issues (because I don't know much about the computer operations), can I impose to ask what might be the basic questions?  Of course, they cannot be "basic", but what I know.     I read "... for Dummies" books, but they did not answer my questions.  I'll try to be brief, but it's not my nature.          So, let's go...

  Sometimes I get request to "update my Adobe Flash Player."  I have looked under Start programs and everything I find is "Adobe Flash Player";  I do not use reader because I do not know how, or its purpose.  But I feel like I'm missing out on thing, why would he says in the 1st place?  (I don't want to watch videos, and somewhere, I think I remember it may have something to do with it.  If so, I peut have a NEED for him.  And if so, where can I find information on how to use it.  Once again, if so, I also NEED the Flash Player?

  Original title: * e-mail address is removed from the privacy *.

  Flash Player is used by some web sites to improve how their web page or pages are displayed. If you go on a site that uses Adobe Flash and Flash Player is not installed on your computer, you will see a request to install Flash Player. When Flash Player is installed, then you can never know its duration as its transparent you when loading a web page.

  In your case and on my computer I installed Flash Player, and for this purpose, I see the same update request that you see. It is best to install the update to the latest version of bugs or security risks that may currently exist in the old version install on your PC.
