Dialog box to open the file on the target in real time

It is possible to load data from a file on a local PC to a VI runs on an RT target? I have a RIO OR the VI running on. From the front panel, I want to be able to click a button and have a dialog pop up where I can choose a local file to load data from. The problem is that when I try to use the spreadsheet VI load data it returns an error indicating that the dialogue has been canceled. If I use the express VI from file dialog, the VI will always return true to cancel. The dialog box never appears. It is not possible to open a local file to a VI runs on a real-time target?

This function will not work in time real (RT).  Please see the bulletin 2S9D21OH knowledge base: creation of a dialog box file for use with LabVIEW Real-time for more information on this.  However, it only locates the files on the target of RT.  If you try to communicate with a file on your host computer, you can be forced to transfer this document to the target of RT, or implement a different architecture for this task.  I would also add that given the user to define the source of the file manually create non-determinisme within your system.  Again, it is perhaps another reason to implement a different architecture.

  • Browse the contents of the hard disk of the target in real time

    Hello

    Is there an easy way to browse the content of the hard drive on a real-time target by using the file path control (or another type of control)?

    What I have in my application is a PC real-time desktop (running on PharLap) who has a Main.vi running on it. There are a few configuration files (for this VI) I want to be able to read and record to that would be stored on the hard drive of the target in real time. However, when the application runs and I hit the Browse button, it displays the contents of the Windows machine and not the machine in real time. Is there something I'm missing?

    Please note that I can send via FTP on the Windows computer to the target in real time and can interact with the drive of the target in real time without any problem.

    Thank you.

  • Can not enter wildcard (*) in the file selection dialog box when opening a file

    It's something I've not seen before. I posted this question in the forum Autodesk AutoCad LT five days ago, but I got no answer at all. Because I'm not sure whether it is a Windows or a problem with Autocad, I thought I'll try to post here, too.

    On one of our AutoCad workstations, when you open a drawing, we cannot enter a wildcard character (*) in the file selection dialog box to help unravel the drawings.

    In other words, say there are 10 versions of a drawing with the number 5008. I should be able to enter the 5008 * and just see these ten designs. On this computer, when I try to type an asterisk (*), I get this error message: invalid character. The following characters are not allowed in file names: \ /: *? "<>

    Now, I know that they are not allowed... but I don't mean to create a file name. I'm just trying to classify them. On our other RTE Autocad workstations, the wildcard character works fine.  What's up with this one? Y at - it a setting or a variable that controls this?

    Thanks - Kevin

    Hello

    ·         The problem occurs with any other application?

    It may be some setting in Auto CAD, which raises the question, and its best you seek help from experts in DAO automatic.

  • Photo of Pixmap vi on the target in real time

    I need to shoot some simple pictures in real time and display by PXI. The image is drawn with the functions of images in the palette of the graphics and sounds. To view through PXI, I found the RT IMAQ video output in the NOR-VISION package. So I need to convert the type of type picture IMAQ. I searched online and it seems these conversions all requires the 'Photo to Pixmap' vi, which I cannot find on the aim of RT.

    Is there another way to convert the picture in picture IMAQ without using this VI?

    AuZn,

    The picture to Pixmap VI is not supported on real-time targets. The only other method I can find to get the pixmap cluster is to use Image 'Get' invoke node. However, if you plan to build this application into an executable, invoke node won't work anymore, as façade elements are removed in executable RT.

  • Need help recovering data of the target in real time. Using NI 9233

    I have a cRio-9012 with 9233 module. I have recently setup of the software for the computer and the target. I have also gone through and set up the "NI 9233 start-up scan mode" to use on my controller. However I couldn't really get the execution of vis data. Could I have missed?

    The VI is executed, but it reads zero while I use an accelerometer (Wilcoxon research model 797-33).

  • Register the event on the target in real time using LabVIEW 2012

    Hi all,

    It seems that LabVIEW 2012 RT does not support user events. Screws are not in the range of function and the help of LabVIEW says that it is not supported. In LabVIEW 2010, everything seems fine.

    That's happened? We need this feature.

    Thanks in advance.

    Hello

    Thank you very much. We will use this workaround, which is not a lot of work if you know what to do. Develop a VI on workstation and the execution of switching left target to the low edge also implements the correct block as well as feature diagram objects.

    This can be fixed in the next patch-Patch because a lot of users could by irritated by this behavior?

  • Why can't I get a glimpse of the indd files in the dialog box to open InDesign?

    Hi all

    It is unfortunate that Adobe does not add a plugin to display a preview of any Adobe source file in Windows Explorer (I mean, except for the PDF but I think that Microsoft did this).

    But I think it's ridiculous that I can't preview the source .indd inside the dialog box to open InDesign files. He says just, "no preview available". I am sure that this failure is related to what Windows can preview... again, not a good excuse!

    It is also the same problem in Illustrator and Photoshop... or program Adobe can get a glimpse of their own file format!

    WHY?  OR how can I fix this?

    [UPDATE: SageThumbs |] [SourceForge.net seems to partially work on several Photoshop files (works reasonably well as long as I limit the file size to 70 mb), it doesn't seem to work with Illustrator files (despite the claim), and it does not work on InDesign.]

    Yet the question remains: why Adobe is not taking responsibility for this?

    I think that for the dialog open regularly, Adobe wants to use operation

    Open the file integrated system of dialogue, so that users are familiar with it.

    and also if they can use the peculiarities of their OS (Windows vs

    Mac have different habits).

    And to solve your problem, they created Bridge (and even Mini Bridge).

    He could theoretically get into the habit to use to open the files,

    That is, instead of file > open it just click on the bridge icon.

  • where the daqmx on real-time target files are stored?

    Hello

    I'm working on an application that is embedded in a desktop RT target.  To make the system easier to maintain in the future, I would like to be able to generate a DAQmx task programmatically to the *.ini file exported from MAX.  In this way, users don't know what my code does to recalibrate the sensors or manage new material; they only know how to use MAX and where to store the files in config on the target.

    Where are the task daqmx, channel, and scale information stored on an RT target?  I have been through the files on the target you are looking for something that contains my task data but have found nothing, while dropping a node of system property in a VI running on the target will give a correct list of the tasks that I set up.  (The project that contains the aforementioned VI has no tasks in it IE: I do not import into the project.)

    Is there a utility that runs on the RT target that can generate a task at the time of the *.ini files exported?

    Thank you

    Exahustive keyword search led me to an answer on the forums.  I'll post here a brief summary in case someone else uses the same key words I.

    1 export the MAX configuration file

    2. write a VI that uses tools in the system palette to load the configuration on the target in real time.

    3 profit.

    In my case, the VI I wrote to download the config DAQmx also generates the configuration files for the screw on the side host and target, so everyone knows what is called tasks.

  • How dio I remove the unwanted of dialog boxes when opening files in FM9

    Everytime I open the fm files in FM9 I am bombarded by a plethora of dialog boxes such as the ADD/EDIT VARIABLE, DITA CROSS_REFERENCE didn't intend to use. During the day, it must lead to probably over 100 clicks to get rid of these while being very annoying. Often, the work area is completely hidden by these dialog boxes. Is there a way to permanently delete these things and only open when we really want to do something like modifying a variable? Thank you very much.

    1roach,

    The feature you're looking for in FM9 is called "Workspaces." Your workspace is selected by using the dropdown in the top right of the window of FM, left minimize/maximize/close buttons. Simply set up the workspace exactly how you like it by opening the dialog boxes (or "pods") you use regularly, close the pods, you have not, fusion as the pods together as you wish, and moving everything exactly where you want. At this time, click this menu workspace and select "Save the workspace." The name that you want, and the next time that you open a document in FM, it should initiate this workspace automatically (assuming that it was the last workspace you had open... He memorizes the last workspace you used).

    For example, I put in spaces of work different for when I'm in the office or work at home (I have larger monitors at work, so I can use the space differently), but also of different workspaces for different phases of the drafting process. For example, I have a workspace for 'creation' which includes the pods for the Structure, elements, Variables, markers and cross reference. I then have a different workspace for working with graphics which has more pods based graphics, and another for the creation of index that has the pods that I use the most when indexing.

    Do a quick search in the help files of FM for "workspace." You will find a ton of info here. Indeed, if your help system is "online" mode and you select "include the results of the community" when searching, the first entry should be a blog entry titled "Workspaces in FrameMaker 9" on May 26, 2009... and the opening of the line is "Tired of loading dialog boxes, modeless, every time that you start your FrameMaker? Sounds familiar...

    Good luck!

  • File copy/delete dialog box is off the screen in a staggered multiple follow Setup

    I'm on Windows 8 on a ThinkPad W520 with a 1920 x 1080 screen and a secondary antibody NEC LCD2070NX 1600 x 1200 display connected via DisplayPort. The NEC is positioned to the left of the ThinkPad and raised higher than the ThinkPad display; the bottom of the NEC is near the center of the left edge of the ThinkPad.
    I put to the top of the poster in the Panel to take account of this arrangement:
    If I have a window of the Explorer of files open in the secondary monitor on the left and use this window to copy or remove some large files or folders, the progress dialog box is not visible. It is currently displayed in the "man no of land" above the main monitor and the secondary screen.
    The problem occurs when the secondary monitor is on the right, or above or below the primary. (I have tested some of these cases, but not completely). Also, this does not happen when the Explorer window is on the primary monitor. The problem does occur at all on Windows 7.
    Here's a film that illustrates the problem. For each image, I copied a large directory on the network and took a screenshot to display side by side and move the secondary display up to about 120 pixels in the control panel every time. You can see how the copy dialog box follows the secondary monitor vertically, but her left side is pinned to the left edge of the main screen, so he ends up disappearing from the screen.
    It is easy to see what is happening here: Explorer normally centers the dialog box of progression on the same screen as the Explorer window that opened the dialog box. This does not work as expected in the direction, but on the axis X to the left edge of the dialog box's get pinned to the left edge of the main screen.
    As the corner at the top left of the primary monitor is always (0,0), it acts as if the dialog box was positioned like this pseudo-code:
    monitor = getWindowMonitor (feed)
    dialog.centerOnMonitor (monitor)
    If dialog.left< 0:="">
    Dialog.Left = 0
    When the dialog box is off the screen, it's a bit disturbing, because it makes the impression that the Explorer window is locked. The only way I know to make visible the dialog box is with this exercise of the superpowers of keyboard shortcut:
    1. use Alt + space to open the system menu of the dialog box. The menu will open on the screen no matter where is the dialog box.
    2. Press m to move (or click on move).
    3. you will see a four-headed mouse cursor, just to fool you into thinking the mouse could do something now. It will not!
    4 instead of this, you have to hit any key of the arrow, which begins the displacement of the dialog box.
    5. now you can use the mouse (or the puree on the arrow keys) to move the dialog on the screen.

    A bit of good news...

    I just tested this on the latest version of Windows preview 10 technical, and it seems to be fixed.

  • Overview of the output only works when the preview dialog box is open?

    The preview of the output adjustment certainly between into force, but only when the output preview dialog box is open, while precisely the preview of the images in playback mode is not possible; It is only possible to preview by clicking on an image and open the dialog of OP. As soon as the OP dialog box is closed, the image reverts to its prior Preview State. This is not normal!

    That's how it has always been. Keep in mind, this is a modeless dialog box, it prevents you to navigate through the file.

    What do you mean by "reading mode" specifically and why you can not use?

  • File navigation dialog box always returns the application folder, not the one I selected

    My script uses a hardcoded destination path to save files. I want to make it more flexible with a file navigation dialog box.

    The function of file selectDlg seems obvious, but it always returns the location of the folder of Photoshop, not the folder I chose in the dialog box.

    For example:

    var outputFolder = Folder();

    outputFolder.selectDlg ("output :"); folder

    $.write (outputfolder);

    Expected:

    My JavaScript console must declare the file I selected in the system dialog box.

    Actual results:

    Regardless of the folder in which I select in the dialog box, it returns always like:

    /c/program%20Files/Adobe/Adobe%20Photoshop%20CC%202014/tmp00000001

    The directory path is where Photoshop is installed on my computer. The tmp00000001 file seems to come.

    Am I missing something obvious?

    var f = Folder();
    var outputFolder = f.selectDlg("Output folder:");
    $.write(outputFolder);
