Display number Variable

Hello world.

Here's what I'm trying to do: I have a double arrow face indicating the distance between two things. The arrow will shorten that two things are closer (these two things are essentially squeezing the arrow), so I'm going to keyframe its scale. I have a number on the arrow, which is the measure between these two things. I would like the number to decrease gradually as the arrow gets shorter. I'm guessing that there is a way to do by parental property 'ladder' of the arrow the number and using an expression that fewer little as the passage of the arrow. Is this possible?

Thank you

You add an expression to the layer of text in alt/option clicking on the Source text. You point the expression of the value of the scale to use. Let's say you make scaling horizontally, then you would point to the X scale value. If your arrow was vertical you remind the value of Z scale. Now, you add a linear method to the value of the scale and if you want integers you round off the result. Say you want the numbers to go from 1000 to 10 so your linear expression would say something like v = linear (t, 0, 10, 100 and 1000)

The expression of integers would look like this:

t = thisComp.layer("Shape_Layer_1").transform.scale [0];

n = linear (t, 0, 10, 100 and 1000)

Math.Round (n);

The expression is complicated if you need figures after the decimal point. This universal Dan Ebberts counter is a good starting point: universal meter

    Failure of Options when you click the Dock icon to include 'Desktop in the display (number).

    I use an iMac 24 "mid-2007. The help documentation tells me how to assign an application to a space is to use this Option. But it does not, while the other three are. Is this an error or something that can be explained? Could there be a work around? My OS is El Capitan.

    Hi peterwhi,

    I understand you are trying to set an application to open its windows on a particular space. To do this, move to the space that you want to use for the desired application, and then choose 'The Office' in the list of options you mentioned see (under Options).

  • 1013 JDev how 2 display number on a specific attribute on the output text table?

    Page 1: I created a form of parameter with 7 top search criteria fields and table of results of search or a Table read-only ADF downstairs. The setting is based on the application of top link where each parameter is as the corresponding field in a table and works very well!

    For Page 2: I want the page looking at the same research, same parameter table of search results albums and even down with the addition of display also count on a particular area so that when someone enters data into the fields of setting up, he would always check the table and show the results of all fields, but in the last column do a count on this field (totally separate from the default number of records to search entire JDEV).

    Is it possible to create as a count or count (*) function at the level of the line of text out? I tried to create a view based on a Select sql statement a, b, c, d, count (e) table, group by a, b, c, d, e and when I dragg this object that contains this sql statement from the data control panel, it gives me the correct regulation of all areas, including the last column to display the number of records for this field , but together does never change based on what has been entered in the parameter, it is as if he is not yet connected to it. For ex: I want to display the number of all students within the setting of the East region, on the contrary it shows total number for all regions, not specific to East.

    Hello:

    I worked on a very simple application form ADF search against table Scott.emp in the Oracle database.
    Now I see what you mean. The idea is probably you shouldn't directly drag and drop control of your data: directly in your jspx as «ADF search form» Here are the steps:
    (1) create your entity object, the view object and I'm in the model layer; (You have already done this, you do not have entity and your view may come of TopLink request;)
    2) double-click the View object in your project of "model"; Add a connection variable: type Bind_deptno Number. It's read in a number of dept on the search engine;
    (3) change the SQL statement of the Emp View object on the same place as 2); WHERE Emp.Deptno = NVL (: Bind_deptno, Emp.Deptno) this indicates ADF if the binding variable is bound to a value
    then use this value, or if it is null, just ignore it. That's the tricky part;
    (4) create a new JSF called "Search.jsp', which will be the search engine;
    (5) from App Module, select EmpView1 (EmpView is updatable, EmpView1 is read-only, but it is not serious on the research plan), drag and drop the EmpView1 on your
    Search.jsp as an array of the ADF (not a search ADF form). This ADF table then displays the result of the research;
    (6) of the control Module of the App, go to EmpView1 data, drag and drop a "ExecuteWithParams" on your search engine like settings-> parameter ADF
    Form, this will tell ADF you want to set the variable binding as an executable looking for shape parameter.
    That's all! and you're good to go. Do the same for the other variable binding (you have 7 search criteria, so you have set 7 bind variable by using the same logic here.
    Good luck and don't forget to mark my answer as "correct" it to make me a few partitions.

  • 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.

  • Display number in build request.

    I found a few old threads about it with no solution, but nothing recent. Does anyone know if there is a simple method to display the version number of an executable built with the manufacturer of the application. I have the build to set to auto increment and would like to be able to see this number in the installed application.

    For the love of light, I mean the build number of the exe file, not the version number of the installer again that I create.

    At present, it seems I have to manually assign a version number and construction and make it visible in the application. For this, I use a different 'about' available from the main routine vi.

    All suggestions welcome.

    Assume I know nothing on .NET, you won't be far from the truth.

    What class do you need select invoke, in the node to access the FileVersionInfo method?

    And it requires specific .NET already installed on the computer, things that maybe I don't have no control is the target?

    There is an example here: http://digital.ni.com/public.nsf/allkb/D45E3A1E694815AD86257173005CFD36

    You will need to have installed .NET, and this solution is specific to Windows.

  • With the help of a number variable in a SQL statement

    Hello

    I am trying to use a variable in a sql statement, and I ran into problems when the variable is a number. The following line of code works if the variable is a string, but not if it is a number.

    "SELECT PAGE 1 UUT_STATUS OF UNIT_UUT_RESULT WHERE UnitID = '" + Locals.LocalUnitID + "' ORDER BY DESC START_DATE_TIME.

    Is there a difference in the use of single and double quotes and the sign for numbers variables +?

    Thank you

    Stuart

    Jervin is almost correct in the post above.

    While it is correct that numbers in SQL are not enclosed in single quotes ('), we still need the entire expression to a string.  If Locals.LocalUnitID is stored as a number to TestStand, you will need to cast to a string so that the string concatination works properly.

    I believe that the correct form is as follows:

    "SELECT PAGE 1 UUT_STATUS OF UNIT_UUT_RESULT WHERE UnitID ="+ Str (Locals.LocalUnitID) + 'ORDER BY DESC START_DATE_TIME'

  • Page number variable based on the anchor text & SEO numbered list

    I looked and looked, not only in Adobe help centers but also just in Google, and I can simply find an answer one way or another to my questions!

    I would like to do 2 things:

    1 use a variable to refer to that page more information can be found on a certain subject (i.e. for more information, please see page #.), even if the page number will no doubt change I have continue to work on this project and eventually build my book from the various documents that I created.  I can insert a kind of marker or anchor text or whatever it is I need the information that I am referencing, as long as it is not visible, of course.  I would just have a dynamic reference, so I don't have to go back through and try to check my page references are all correct.  The variable of the current Page will help me not in this case.

    2. I would also like to refer to numbered tables I have; they are currently configured as being numbered by a custom paragraph style which is mode number, 'continue previous number "; Another situation where the table numbers will change because I continue to work on this book and I want a dynamic solution.  If I need to insert a variable to calculate the numbers in the table, rather than using the paragraph numbering style, it is very good; I prefer to do a little more work now, so that I can be sure my references are accurate, when this is said and done!

    Thanks in advance for any help you can give!

  • Display number in the area of dynamic text without rounding

    Hello

    I use AS3 and try to place the extracted value of an OC in 2 dynamic text boxes. I use a couple of numbers of test (2.25 and 1.25). Strangely when I run the following script, I have trouble getting my test numbers in areas of 2 text (T1, T2). (Before the numbers stopped show altogether, they have been rounded up and that he seemed to be 10 x greater than they actually are, without my something like that.) Note: The script also displays the text (T3, T4, T5, and T6) boxes with messages like "above average" based on the scores don't know if these screens are correct, since I can't show 2 numbers inspired by the poster.

    Here's the code. I have to do something wrong:

    Btn1.addEventListener (MouseEvent.MOUSE_DOWN, mouseDownHandler);
    function mouseDownHandler(event:MouseEvent):void {}
    var so: SharedObject = SharedObject.getLocal ("G1", "/"); using ' / ' as a local path should work to pick up the SO created by the SWF quiz
    var read1:Number = so.data.value1
    var read2:Number = so.data.value2
    var read3:Number = so.data.value3
    var read4:Number = so.data.value4
    T1. Text = String (read1);

    {
    T3. Visible = true
    T4. Visible = false
    T5. Visible = false
    T6. Visible = false
    }
    ElseIf (read1 > = 2.65)
    {
    T5. Visible = true
    }
    otherwise if ((read1 < 1.95) & & (read1 > = 1.25))
    {
    T4. Visible = true
    }
    ElseIf (read1 < 1.25)
    {
    T6. Visible = true
    }
    }

    Any help appreciated.

    Try just the text assignment clear ole to the textfields.

    T1. Text = "ole plain text."

    If you're not yet see anything, my inclination is first ask you to check if the font for the textfield color could match the background.  If this isn't the case, then are hide you, rotation, or animate these textfields - in which case you should join the police for them.

  • Display number date in report

    Hello

    We receive the date information in the format DDMMYYYY and have the card in the number field. I want to show this as dd/mm/yyyy date info in the report.
    For example, if the date is 10072009 (10 July 2009), it should be displayed as 07/10/2009 in the report.

    I tried to
    (a) CAST the channel number, but which was not allowed.
    (b) first to cast the integer and then cast in character. But when I used the RIGHT function to get the last 4 characters, it did not return any values.




    Suggestions how to approach the issue?

    Ady

    Hello
    You can do this by using the CAST and String functions.

    Here is an example of the formula-note that I use recipes counts as base, this can be replaced by any number, whole or currency field:

    LEFT (CAST (account. (("" Annual sales "AS CHAR), 2) | '/' || INSERT (SUBSTRING (CAST (account. ((("" Annual sales "AS CHAR) OF 3), 3.0, ' / ')

    See the online help for the full description and use of the various functions:
    LEFT - clips off the first characters
    INSERT - adds a character string
    Substring - clips off the last characters
    CAST - convert from one type to another
    || -double pipe is concatenation

    Your error may have tried to Cast to a String - there is not of type 'String', CHAR performs the same function.

  • IPhone does not display number of unread emails

    Hello world

    I think I'm getting a problem with my iPhone.

    In iCloud, I created some rules for incoming emails and I am moving them to a custom folder. I see the same configuration on my mac and my iPhone.

    In iCloud and Mac, I get a label with the number of unread emails, but not in my iPhone, so when I'm on the city and check my emails on my iPhone I never see a notification or a label with the number if there is new e-mail messages. Here are some pictures of my settings!

    In the first image, there is records who created the iCloud (synced with no problems) and I know that I had new e-mail messages, but as you can see no folder only shows the number of new emails. I can see it on my mac and in iCloud but nothing in the iPhone.

    Thank you!!!

    Hello Jarkaos,

    Thank you for using communities of Apple Support.

    I see that you don't see notifications to your e-mail application. I have a number of things for you to try to solve this problem.

    First of all, quit the Mail, Force an app to close the iOS application

    Then, restart your iPhone, restart your iPad, iPhone or iPod touch

    Finally, to test the issue.

    If the issue is not resolved, follow the same steps, but this time make the "force restart" of the second article and test it.

    Is the best.

  • Expect the icon display number in the table of Boolean

    Can someone shed some light on a piece very little icon that I receive on a function 'boolean array number?

    I seem to be getting a little "wait" icon superimposed in the corner. The help context entry looks the same, and the feature looks the same (as far as I know).

    The piece of code that I use has been converted to a newer version of V8.5 but apart from who should have nothing unusual about that.

    The illustration below shows the offending icon with another who is fresh out of the palette next to him.

    Am I missing something?

    Thanks in advance for advice.

    The wrong icon with registers for previous and the new 'sign Extension Modes' right-click menu options that have been added to this feature on the FPGA diagram in LabVIEW 8.6 or later.  The bug was reported as CAR # 122749 and should be fixed in a future release of LabVIEW.  Apparently, the function may return incorrect values when it has a weird icon, so I recommend you remove it and drop a new to the case where.
