How to make a shared variable, which is an update on the host channel?

Hi all

I'm relatively new to LabVIEW, so I apologize in advance.  I'm working on a vision for research application and I'm trying to convey an image of the smart camera target to the host.  I flattened the IMAQ image to a string and pass the string to a shared variable.  On the end of the host, I unflatten image and try to post to see if I don't really get the image data on the host.  However, it only displays the first image and after that the image is not updated.  In addition, the shared variable itself is not up-to-date.  I have a loop timed on the target and a loop of simulation on the host.  Help or direction would be appreciated.

Thank you very much.

I thought about it and will post here just in case it might help someone else.  For some reason, the IMAQ flatten channel gives a format that did not like the unflatten of the chain.  When I have no flat chain, it didn't recognize it as an image.  Instead, I just used the generic flatten the string on the target and then block when I have not flattened image on the host computer, I had to only give the guy I got to report the allocation of memory IMAQ.  Maybe I'm just slow, but if this helps someone else, fine.  Thanks again.

  • VBAI: How to read a shared variable?

    I'm doing my inspection to do things that depend on the value of shared Variables. How to set the VBAI Shared variables, it is obvious, but I didn't understand how to read them and then create some kind of a structure of MATTER using this variable.

    Any ideas on how to implement such an architecture?

    I create two different States and use the transitions that are based on the value of the shared variable. You can read the value of the variables or the previous measures in stages that allow this (not all stages, but most don't) or transitions. To create a new State, go to the state diagram (click on the 'toggle window view hand' so the State-transition diagram is in the main part of the window). Right click in an empty part of the state diagram and select "create a new State".

    To create a transition, right-click on a State and select 'Create a new Transition' and drag the transition to the new State.

    To change the transition, double click it and you will be able to select the shared variable as measurement, and comparison operations to make the decision. If this comparison is false, the default transition is taken instead.

    Select help > Show context Help if you change the schema of the State for more details on how to use it.

    Hope this helps,

  • my 500 vacation photos are now on the lists section of the control panel-display wallpaper how to make their return to which they belong?

    Downloaded the camera vacation photos and sorted by them by putting each location days in it is a separate file. I also received a disc of NASA just with scenes of wallpaper on it and downloaded it.  These points of view, NASA, to another disc I changed once a week. I keep them in a separate folder named desktop wallpaper photos, in my position of photos. I went to change this view for weeks and not only discovered that all these photos have been in the display list folder / in Control Panel, but also all the pictures in the files of our holiday, which should have been in the image file in my documents. There are also pictures of my family photos files that are in the selection of wallpaper from the 'view' file in the documents.  I will return to my pictures folder and there not a file here for them, which means that it is not a copy of the file, but the actual file. I did not do in the lists of display/control panels. How can I remove or cut pictures that came the wallpaper display lists and put them in the my documents/images files where they should be. Tried to cut and paste functionality, but nothing of this nature appears.

    Hello

    Navigate to the folder where the photos are and then right-click on the image and click on copy and then open the folder My Documents/photo then right-click and press on paste.  Since you have a lot of picctures you can hold CTRL and left click each photo in this way they need only hit copy once.

     
    I hope this helps.
  • How to make a web page which changes each time the user refreshes? Is it possible to Muse?

    Hi, I would like to make a simple site where the main text in the center of the page changes whenever the user refreshes the page in their browser. I guess I'll have to do a master and several pages that are all the same except for changes in the text, but I don't know how to make sure each update goes to another page and not just the home page? Is it still possible in the Muse?

    This is an example of what I'm going: : procatinator:

    Thank you!

    You can't do it with only Muse. Would be probably pretty simple to do with a bit of Javascript. Check the widget directory such that it is possible that someone has made a widget for random content. If not, maybe I'll do one this weekend. ;-)

  • Shared variable between 2 LabVIEW executables via the network

    Hello, I need to create a number of network shared variables by two (built with LabVIEW 8.6) executables running on two different computers on a local network. The library to invoke node returns an error when you use a different IP than localhost. even more, it is not clear to me what exactly I have to do (what executable deploys the library, on which targets, activate the link or not, so on...). Thanks for any help, if you have already managed to make this communication works properly...

    Thanks for the replies. I've found the last two documents, but the first one is the most interesting: if I can't put the sources of two applications in a single project, I will move to another solution (data as suggested by Mike sockets or TCP). The two original projects are larger, and their merger would lead to such a huge thing!

  • How can I display a variable evolution in a Subvi on the face before of the main vi as the Subvi is excuting

    In the attached document the vi on the right is sub to the vi on the left. On the Subvi on the right of the variable "playing field" is continuously updated on the façade of the Sub - VI as the loop 'for' is executed, but only the last value of the variable is updated in the table main before vi which is what is expected. My question is how can I display the evolution of the value of 'Playing field' on the main façade of vi that the loop 'for' in the Sub - VI is running?

    Thank you.

    I don't have the drivers you are using. But here's an example of how update an indicator of a Subvi. To create the reference control in the Subvi, select control refnum in refnum palette and drag a numeric (or other) on the refnum control.

  • How to make still photos of my camera of Lenovo to the appropriate library to upload on a social networking site (Facebook, not)?

    First of all, I'm 50 years old and I grew up in the time before the PC, so I am very naïve.

    I have a laptop from Lenovo and it has a camera in it. I recently discovered that it can take still pictures, so I took some pictures of me.

    Now I want to download pictures to an online community, I belong to where I have a profile. But the photos are not in my images on Microsoft Word, or in Windows Media Player or any library I can find.  They are in the box in the photo section.  How can I get them on the part of the camera on the computer in a place where I can then download them to my profile online? Where should I store, and how to make them here?
    I appreciate your help.

    Hi James,

    I see you want to download photos of the Lenovo built in webcam for a social networking site still. I'll help you with this problem.

    1. what operating system is installed on the computer?

    2. what security software is installed on the computer?

    Please follow these steps and let us know the status.

    1 - click on "Start" and start the webcam software. Every computer manufacturer take its computers ready webcam with a specific software for the control of the camera.

    2 - Click on 'Snapshot' or 'Take picture' (or similar) in the program to capture still images. Most of the programs of webcam show you what see your webcam, as soon as the program is open. When you move, the webcam image also moves. Specific commands vary from one program to a program and manufacturer in the manufacturers, but the standard webcam software has a "snapshot" command to take a picture.

    3 - Click on 'Tools' and 'Settings' (once again, or similar) to change the way the webcam records still images. You can configure the quality of the photos up to a preset maximum resolution. A webcam software allows you to save a series of images or to add digital effects to the pictures. That depends on the camera photo and its software by default, too. While in the 'Settings' window, find out where the pictures are stored. Each program stores pictures in a different location.

    4 - Click 'Start' and 'Computer' to open a file browser. Find the folder where the webcam stores its photos of step 3 to change the photos with a graphics program or to delete and rename files. To send photos to your friends and family, open your email and attach photos to this folder. Webcams store photos in smaller resolutions, so you never get hurt to send these files as attachments, even with a very slow Internet connection.

  • newBie Q: how to make a clickable form to access a slide with the same name of the form (button c_1 drag c_1 f.e.).

    I've done a few clickable placeholders on a masterslide

    PS I use a trial version to test a branched interactive scenario. A choice of a user driven tot another slide with a followed video reaction of other choices,...)

    Not possible to use a variable in this case to link the label name for a name for the slide.  But I still don't see the purpose at all?

    Will you need to the same button with the same name on multiple slides? Will you use for the rest of the project timing in this case? Because you cannot reuse a name of a button, if you have two instances of this button on two different slides, they will need each a different name. If this is the same form button, programmed for the rest of the project, we will always use the same action, needs not even a tip action because it will «Pop X zip» But there is no way to use the name of the button in this action at all. Joint action is possible with X as the parameter, and then you can assign it to all the buttons that have need of this action. But why do you want that the link between the button name and the name of the slide?  Can you explain? My Captivate intuition tells me that there is a misunderstanding, perhaps because of your experiences of Lectora. Captivate is really different, presented on the differences in workflow with an expert Lectora. I no longer use Lectora but the structure, and certainly the way to 'script' is totally different.

    Hello

    You may need this resolved at this point, but here are a few tips.

    An example of a loop in a dynamic array is here: Re: how to make invisible/visible or hidden columns with checkbox?

    You are usually not necessary to resolve the nodes, especially when the script object is in the same table as the target objects.

    For example if the table was not static your script could be simplified:

    if (this.rawValue == "1")  // this object is in Row2
    {
         Row4.ComplianceCheck_L1_1.mandatory= "error";
    ...
    }
    

    However because you will be to loop through all the rows in the table repeatable instances / then you need to resolve the nodes. Take a look at the example above.

    In your script, you have to Row8 Row4. I don't know if this is repeatable or just some of them. If we take Row4 as being repetitive, then you can apply the following to all repeatable lines.

    var vRow4 = Table48._Row4.count;
    console.println("Row4: " + vRow4); // You can delete this or comment it out after testing
    
    if (this.rawValue == "1")  // this object is in Row2
    {
         for (var i=0; i
    

    I have not tested, but it should be close to work.

    Good luck
