How to create a Subvi without controls?

Greetings,

I go through exercises to learn LabView and I have a question.

One of the exercises in my book is to create a Subvi, which generates a random number in a range of minimum/maximum.  (OK - re - invent the wheel)  I have the block diagram and I have the icon, but I have trouble getting the wired connections.

Currently, it is a static value hardcoded for the min and max.  I wish I had a connector in each of the min and max (so that the parent can specify that however, he wants to be with a static integer, one entry, etc.) and then a connector for output - once again, without a control specified so that the parent can take the value and run with it.

How to do wiring?  I can obviously fall into the controls in the front panel, but my parent project doesn't have space for 3 additional orders coming on it.

Thank you

newbo

In the connector pane, you can right-click on a connector and select a setting.  You can assign "this connection is->" recommended or optional.  This will allow the VI to be called without these wired terminals of the parent VI.  If the left unwired, will serve as values by default that you put in the controls.

  • How to create the hierarchy without creating a Subvi files

    Hello

    I have an existing LabView program that uses blocks of Subvi.  I want to change it so that I can't copy files Subvi (when I transfer the program to another computer).  The goal is to have a single file/program that I can copy, paste, and run on other computers.  So, I want to know if there is a way to create the hierarchy without creating a Subvi files or how to integrate the Subvi in the program.  My program and Subvi files are included here.

    Thank you

    Rocky

    You can create a version in an executable file.  It would be the most common way if you insist on having a single file.

    You could also build a source distribution in a zip file.  Then you just copy and paste the zip file and unzip it anywhere where you want.

  • How to create a strictly typed control refnum using LabVIEW scripts

    I want to use LabVIEW to create a strictly typed refnum control that is bound to my custom control (a defined cluster), but I'm not familiar with scripts and can't see how to do it.

    If I create a new object of VI, with Refnum of control as the Style, how can I give my custom class object VI control terminal? When I try to use a reference to my control.ctl file customized (using the Open VI reference) I get an error: 'error 1057 occurred... ". Type mismatch: object cannot be cast to the specified type. »

    Alternatively, if I create a new Refnum of control as above, using a standard Cluster as the object of VI class, how I can convert this refnum control to a strictly typed refnum, which is related to my custom cluster control type?

    Thanks in advance for any advice,

    I tried, and as usual, things were slightly different.  The big problem is that a constant control reference becomes a node, not a constant, so cannot be converted to a control.  The good news is that you simply move to the front of the new control, as you would in the dev environment.  Here is the raw code (always needs cleaning to close the refs and add save of the new control, and more, you don't need to show the FP control if you do not want).

  • How to create the EM Database Control in Windows, if the Service has not been created initially

    Hi all.

    The procedure to re-create EM 11 g Database Control is described in note Doc-ID 278100.1 .

    I have to administer a new database that is located on a Windows machine and I find the Service control database EM missing, so I assume that the database has been created without EM.

    My question is this:

    Can I use the procedure described on Doc-ID 278100.1 ?, I mean it is to recreate but I guess it still applies for a new installation.

    Thanks in advance!.

  • ODI 12 c how to create the table without number (38.0)

    Hi gurus of ODI.

    I got following problem:

    I have a copy 1:1 with the addition of metadata and a delta on the side to find target. When I look into the target in several numeric columns, the values are truncated, I lose precision.

    What ODI research I found the problem to the work table.

    All affected columns are defined as number without giving any precision or scale, in the target as well as the source.

    When I ran the simulation to see what ODI I noticed that, in the creation of the work table statement ODI number is used (38.0) for all numeric columns where no precision is explicitly given.

    It is so clear when ODI loads the data from the source to the working table the values of the numeric columns are truncated.

    My Question now is, how do I know ODI is not to use the number (38.0), but simply of number for the numeric columns with no details given when a work table is created?

    I know I could explicitly give precision and scale for each column of numreic, but it would be a lot of work and for some of the columns the precision required is not known, then that would be the worst Option.

    Thanks for the help

    I found myself where was the problem, then I write the answer, while others may find it here:

    The mapping was

    Source--> Filter--> Expression--> Join--> target.

    The join joins anothher Table.

    In the target, the instructions for completing the columns have been Expression.ColumnName

    I changed it to be Source.ColumnName

    The Knowledgemodules delivered with ODI treat different columns depending on how they are.

    In the creation of the work table, firstly everything all computed columns in the Expression or read from the expression by other components, including targets. It then uses the presission and scale in the component expression with number (38.0) by default if it is explicitly given. Items but which are directly read from somewhere before the expression are also saved in the work table, it ODI use the scale and precision holding of the source - and when the Source's number without taking into account the precision and the scale he uses just number.

  • How to create a text WITHOUT a caption field?

    This must be a ridiculously stupid question, because I've tried Googling all possible variations of this question and come up with squat.

    I got a form in excel, converted to a pdf, it imported into LiveCycle and am trying to add fields where the wizard didn't. When I create text fields, he almost always puts in a legend, despite the fact that I don't want one. I can't resize to remove it and I don't want that, but I don't know how to get rid of it.

    On a colleague's computer, I was able to create without caption text fields - the caption in right field properties field is dimmed. In fact, when I pull a form created on this computer, all text fields, I create have no subtitle. When I create a new document on my own computer, they are all legends again.


    On an unrelated note, why is that what forms I create in this way do not have the PDF option Preview? It is just gray.

    Select the field, then go to the tab "layout". Inside, there is a section called "Caption". Select 'none' in the drop down menu.

  • How to create the Webservice data control with a secure Web service?

    I am creating a data control with a Web service that requires authentication (SSO)

  • How to create a hotspot without a break?

    I have a video full length which is 60 seconds long. The seconds 34-36 an object appears and the test taker should click anywhere on the video. If the hotspot is 100% transparent and covers the entire video.

    I need to somehow add a slide that will only last 2 seconds, and if the user clicks on the video in the 34-36 seconds he gets 5 points. If he get-0.

    Also, I need to monitor/number of clicks. Each click, I show a flag at the bottom to show that the trigger has been registered. I need this to prevent users to click constantly and complete brand every time. Also if too many clicks are registered within a certain time--> disqualified.

    Can anyone suggest what to use?

  • Adobe Captivate 7 - How to create a custom without the function table of contents table of contents?

    Hello

    I want to create a table of contents in my E-Learning-project because the automatically generated TOC of Adobe Captivate 7 includes all the features I need to check for example chapters which are the groups in the film strip.


    I use master slides in my project.
    The table of contents, I need must be designed and programmed as follows:

    1 intro / title slides

    9 chapters

    The progress of the work - 3 status - all chapters should be moved by symbols in the table of contents

    Symbol 1: chapter has not yet begun (just an empty box)

    Side 2: chapter is work in progress (a square with a green triangle inside)
    Side 3: chapter is finished that means that all of the slides in this chapter are read (the square is filled with a green square)

    All the chapters and Points to the table of contents must be clickable (links) maybe with a mouse over effect (change in colour of mouse) and should start to the first slide of this chapter.

    The chapter which is open must be written in bold with one blue color, others who are not open to be written in the normal font with a black color

    I think it's a little complex, but solutionable.

    I think I need to create three symbols of the buttons form, advanced actions that tend to fade and fade out named symbols.

    Is there someone who can describe the process of creation? Where should I place all the functions, actions and so on? On the slide master?

    Thank you for the answers!

    The only thing I can say about it is that I build it in Flash, so it could be dynamic and reusable.

    If you take the time to build a PC inside it only works for one project. Certainly you would have a base to work from, but for a another edition project wouldn't be fun.

    If you need HTML5, I think it would be much more difficult to build a dynamic table of contents.

  • How to create a recovery without a disc writer drive

    I want to create a recovery disc for my 13 edge that has no internal disc burner.

    Unfortunately rescue & recovery does not offer to create an ISO collection that I could then burn it on another computer.

    I have an external DVD drive, but no writer. So, I'd be able to boot from a CD of restoration if I could create a.

    I inserted a USB and Rescue and Recovery can write to it, but in my experience USB keys are lost or overwritten easily so I prefer a CD as recovery media.

    So my question is:

    Is it possible to make a key USB bootable recovery CD, or perhaps create an ISO with R & R recovery disk?

    Or can I just burn the stick as a data CD?

    ADD ON:

    I just tried to test booting from the USB stick recovery created but it did not work

    I was able to select the USB key to the F12 prompt, but the screen stays white with a underscore cursor in the upper left corner. After 2 minutes, I gave up and started normally new so I don't always have a recovery media.
