• Two copies of Firefox open. How to close one without losing the lugs on the other.

  Firefox has been slow to open up, so after awhile I clicked on the icon a second time.
  Then two copies opened, one with this page of solution of Mozilla and the other with all the many tabs that I use frequently.
  But when I tried to close the copy of solution of Mozilla, I was warned that the two copies would be closed, I know from
  experience can sometimes cause me to lose all the tabs on my master copy.
  So, how can I safely close a copy without losing the tabs on the other?
  Thank you.

• How to implement a callback to the help function call library function node in LabView?

  I try to call a fuction from a SDK.dll library by using the node call library feature. The SDK has been provided to

  me and I don't have the source code, just the .dll and .h files.

  The SdkSetPropertyEventHandler function has a function of recall as one of its parameters. How to apply the

  callback using the NSI node? I'm a good programmer LabView but this is my first time using the library to call

  Function node. I read all the info I can find on the web site of NOR and the discussion Forum, but can not understand

  This one out. I'm using LabView 8.6.

  The deacribes SDK.h function as:

  Function: SdkSetPropertyEventHandler

  (SdkSetPropertyEventHandler) SdkError SDKAPI
  SdkCameraRef inCameraRef,
  SdkPropertyEvent inEvnet,
  SdkPropertyEventHandler inPropertyEventHandler,
  SdkVoid * context);

  //
  Description:
  Registers a callback function to receive the status
  change the notification events for the States of property on a camera.
  //
  Parameters:
  In: inCameraRef - designate the object camera.
  inEvent - designated one or all the events will be completed.
  inPropertyEventHandler - designate the pointer to the callback
  function to receive the camera property-related events.
  inContext - designated application information must be passed
  way to the callback function. All the data necessary to
  your application can be passed.
  Output: no
  //
  Returns: A sdk errors.
  -----------------------------------------------------------------------------*/

  A separate header called SDKTypes.h file contains the following data:

  typedef SdkUInt32 SdkPropertyEvent;
  typedef SdkUInt32 SdkPropertyID;
  typedef void SdkVoid;

  typedef struct __SdkObject * SdkBaseRef;
  typedef SdkBaseRef SdkCameraRef;

  /*-----------------------------------------------------------------------------
  SdkPropertyEventHandler
  -----------------------------------------------------------------------------*/
  typedef SdkError (SDKCALLBACK * SdkPropertyEventHandler))
  SdkPropertyEvent inEvent,
  SdkPropertyID inPropertyID,
  SdkUInt32 inParam,
  SdkVoid * context);

  Thanks for your help.

  Hi Rolfk,

  You are absolutely right. This article describes what you were talking about? I'm just trying to get as much information as possible on this thread if the solution is easier to find for the future. Thank you.

  Yes, but I find the idea of using .net to call a LabVIEW VI as callback function C a bit as using a roll of Steam ironing your pants. Why do it? Well the steamroller has extra security guards that make it less likely that you'll break your pants in the process, but it's not elegant IMHO.

  Write a C DLL that translates between a C callback and a user event LabVIEW using the PostLVUserEvent() of the interface of the kernel to run LabVIEW function seems so eleganter for me. Yes, it's a bit of programming in C, but good!

• How to copy DAQmx task without the help of MAX?

  Howdy-

  I hit a bit of trouble here I think points to a fundamental misunderstanding I can have on DAQmx channels and tasks.  I can hack together a workaround, but I would like to know how to do these things, common sense.

  In a Word, I prefer to do everything in the code and not use MAX.  For my application, I would like to create a single channel/task initialized with all the scaling, the physical channel parameters and units (it is what is, in my case, a 'channel').  I would then like to create copies of this channel/task and configure each with parameters of specific task of sampling... corresponding to what I would call the "tasks" to use "Channel".

  I'll have no chance, so of course, I do not understand what I do.  Any reading/posts I've met use MAX.  Here's what I've tried so far:

  

  Even when you try to use MAX, I am the breath.  Any help straightening on my confusion here is very appreciated.

  Thanks in advance and have a nice day.

  -Brad

  In fact, you're not confused.  In this instance of National Instruments is perhaps...

  See the links ofthese ideas in the link.

  But a 'task' is really just a section in an XML file.  If this file is named *.lvproj the project has access to tasks.  If this file is *.nce any labview application has access to tasks.  If this file is created by the RTE that vi has access to the task.  In short, the "tasks" are never really defined by 'Code' but by the XML code to the file than declairs them and teir properties.  Tasks need to be defined a time-preference during design - project

  Yes, it's a bit simplistic but a good analogy!

  Go ahead and kiss MAX to set your tasks... use DAQmx property nodes if you need to programmatically determine a task property.   "do everything in code" as you say is just not really the way it is... the way I think you hear it...  'S really not 'made it in the code"but rather how LabVIEW is inherintly multithreaded.  The IDE just handles it for you "So easy that could encode a cave man!  Relax and let it work the way it does work for you.

• How to republish one FMIS in the other streams

  Hi guys,.

  We are 24/7 streaming live from a number of OUT to the FMS server interactive for a livepkgr app cloned, and our customers, listen to Flash via rtmp and IOS via HLS.

  Since we want to set up another server (to be able to serve more customers), the question is - hot to republish a different server so that both servers can stream rtmp and hls to customers?

  We already use the url stream on a backup server backup in OUT - cela us do not want to change from the backup server is just that - the backup, if the primary server goes down.

  Could someone point me to a SSAS sample code that will do this (and work within existing main.asc livepkgr which has not changed, except the parameter 'append' is changed to 'save')?

  I will propose.

  1. create an app name it say ingestapp. Place a main.asc

  application.onPublish = function (client, myStream) {}

  trace (myStream.name + "publishes on request" + application.name);

  This is an example of using the publishing feature multipoint to republish

  stream to another instance of the application on the local server.

  reissue of first server

  trace ("republish the stream in livepkgr1/_definst_");

  NC1 = new NetConnection();

  NC1. Connect ("rtmp://localhost/livepkgr1");

  ns1 = new NetStream (nc1);

  called when the NetStream server has a status

  ns1.onStatus = {function (info)}

  trace ("stream status:" + info.code)

  If (info.code == "NetStream.Publish.Start") {}

  trace ("publishes the stream");

  }

  }

  ns1.setBufferTime (2);

  ns1. Attach (myStream);

  ns1. Publish (myStream.name, 'live');

  next server

  trace ("republish the stream in livepkgr2/_definst_");

  NC2 = new NetConnection();

  NC2. Connect ("rtmp://localhost/livepkgr2");

  Ns2 = new NetStream (nc2);

  called when the NetStream server has a status

  ns2.onStatus = {function (info)}

  trace ("stream status:" + info.code)

  If (info.code == "NetStream.Publish.Start") {}

  trace ("publishes the stream");

  }

  }

  ns2.setBufferTime (2);

  ns2. Attach (myStream);

  ns2. Publish (myStream.name, 'live');

  }

  application.onUnpublish is function (client, myStream)

  {

  ns1. Attach (false);

  ns2. Attach (false);

  }

  (You can write much better managed code...) It's just an example)

  2. create two application, livepkgr1... livepkgr livepkgr2... In above code, I assumed that the two are on the same server, if you change the server and keep the application of livepkrg even name.

  3. from GFFE, instead of publish livepkgr, publish on ingestapp... otherwise keep everything even.

  4. from customer to subscribe to livepkgr1 and livepkgr2 and correct server...

  so in this case, OUT feed to ingest the app and ingest app working as a driver for several applications of livepkgr... Hope that clarifies...

  Kind regards.

• 3 documents are the same how to keep one and delete the rest

  Title: many
  I save a lot of letters, files etc in MY DOCUMENTS for the engraving or printing at a later date, now I find there are THREE my documents on the desktop and do not all have the same information stored in

  I moved all necessary letters etc. in one my question is that how can I remove all but one of MY DOCUMENTS?

  Thanks for any help

  Don

  There should be a "My Documents" folder for each user account on your computer.  For example, if you have configured your computer with two user accounts, Don and Phyllis, there should be C:\Documents and Settings\Phyllis\My Documents Settings\Don\My Documents and C:\Documents.

  Please answer the following questions:

  1. When you say you have three "My Documents" on your desktop, they are records or they are shortcuts (with the arrow curved in the lower left corner of the icon)?

  2. for each of the three folders "My Documents" on your desktop, right click and select Properties.

  • If the icon is a shortcut, select the tab "shortcut".  Copy the information that is in the 'Target' box and paste it into your reply here.
  • If the icon is not a shortcut, select the tab "General".  Copy and paste the information after the word "Location" in your response here.

  Once it is clear that these elements of "My Documents" on your desktop actually represent, I can suggest ways to consolidate things.

• How can I download pictures without the help of Photos?

  V10.10.5 using OS X Yosemite with pictures v1.0.1. I would like to upload RAW files without having to import through Photos, because I want to change them. Unfortunately, I was not very successful. While exporting pictures (RAW) images in a folder, the images have been converted to jpg. :-(

  Therefore, how can I download photos from my camera without using pictures?

  Download from where to where?

  Usually you download using Safari or another web browser and click load and select the RAW file wherever you downloaded it to disk

  If you talk about form of import a mount of the camera the card in a card reader and use the finder to copy the files to the location you want RAW format - or use Image Capture to import them to any desired location

  And importing RAW woes not convert them to JPEG using the finder, transfer of images or Photos - each of these copy the RAW file as that disc for your use, you choose

• Comenting code - style - how to keep coments anywhere - without the help of sequences

  Silly question perhaps on the style of comment.

  Basically, I want to use the sequence boxes to keep the comments on my diagram opposite the bits of code that they referred to-otherwise, when you use cleaning diagram (which I'm afraid that I use all the time) they're going anywhere.  It is good - except that I found especially when doing the FPGA programming sequence boxes reduce the amount of parralelism that can go on--since the 'box' must end before one of the outputs can be used.  Is there another method I should use rather than areas of sequence to keep the text beside items - but does not require that a set of items are fixed in one place?

  You can vote for this idea. The decoration of the flat frame under the range of structures is better to highlight a section of code than a sequence structure. Of course, it will not include the code and you will mess up the cleaning of the comic. I personally don't use cleaning comics often but when I do it's only to clean a selection. Never all otherwise, I have more work to do.

  I'm quite OCD about the cleanliness of the bd, but recently I started everything just do not worry much that the VI is almost done. So only I make sure that there is no pixel wire bends, subVIs are aligned and spaced perfectly, and comment boxes are in the right place.

• Deploy multiple virtual machines from one model to the help of customization of the OS and a text file for hostname and IP

  Hi all

  Not sure if this has already been answered, I did a search on the forums, but couldn't find an answer to what I'm looking for.

  I want to fully automate the deployment of multiple VMs of a model using a customization file, but also to retrieve the host names and IP addresses from a text file / spreadsheet.

  for example:

  I need to deploy a test environment of 30 virtual machines using the template file and customizing TestVM. I have a spreadsheet with the VM host names and IP addresses. The process now is to manually enter the host name and IP when the customization file invites to do while deploying them in each virtual machine. The customization file takes care of the rest (license key, admin password, add to the domain etc.) can I automate entry of the name of host and IP addresses in reading from a text file?

  Thanks in advance!

  Take a look on the deployment, customization and modification of virtual machines to a csv file
