Function call does not

I created the following function in a java file called "ProgramScreen".

public void SetLineWidth (int crack width)
{
_width = width of stripe;
}

If I call the function in the java file "Program", it works.

Screen ProgramScreen = new ProgramScreen (this);
pushScreen (mainscreen);
       
Screen. SetLineWidth (1);

If I call the service from a java file different that they do not compile I get the following error; "Cannot find symbol.
' symbol: SetLineWidth (int) method.

Screen;
       
screen = this.getScreenBelow ();
screen. SetLineWidth (1);

If I put a watch on the screen, it's the same as the screen.

How can I call the function I created in ProgramScreen from a different java file.

Thanks for the help!

Because the function is valid for your class. You will need to catalogued the display to your class to call it. You can only call functions defined in the Screen class on a Screen object.

That is to say

Screen ProgramScreen = this.getScreenBelow ((ProgramScreen));

  • function call does not - why?

    Hmmmm.  I don't see why it does not work.  I have an application with a new class that I just created.  The load class, but he will not call its own internal function.

    package com.parkerandkent.components.classic.photogallery {}

    Import caurina.transitions.Tweener;

  • Oracle query of relay and access function call does not return the list

    Thanks to aid in a previous post, I received, I created an oracle 10 g feature that returns the list after you run the sql code it contains. It works in oracle, using sql developer.

    I need to have the list that he returned to see the place in MS Access via a relay request. It does not work so far. The string for connection etc is ok, I'm able to use passthrough queries to run sql strings correctly. But when I try to call the function through the request of relay and access initially nothing seems to happen (IE no list) and if I try to run again, there is an "ongoing call odbc error. Current operation cancelled "." There are only three records in the table. I'm missing something, someone can he spot?

    The application of relay and looks like this

    Select * from fn_testvalues of the double

    Once that is running in oracle.

    To create the test table and 2 functions below.

    CREATE TABLE t_values (MyValue varchar2 (10));

    Table created
    INSERT INTO t_values)
    SELECT 'Merced' c1 FROM dual UNION ALL
    SELECT "Pixie" dual UNION ALL
    SELECT "452" DOUBLE);

    3 lines inserted
    FUNCTION to CREATE or REPLACE RETURN NUMBER IS fn_isnum(p_val VARCHAR2)
    n_val NUMBER;
    BEGIN
    n_val: = to_number (p_val);
    RETURN 1;
    EXCEPTION
    WHILE OTHERS THEN
    RETURN 0;
    END;
    /

    Feature created

    table test:
    SELECT val, isnum fn_isnum (MyValue)
    OF t_values;

    VAL ISNUM
    ---------- ----------
    Merced 0
    Pixie 0
    1 452

    Now the function that is called in the application of relay:

    create or replace function fn_testvalues
    sys_refcursor is back
    RC sys_refcursor;
    Start
    Open rc for
    Select t_values.*, fn_isnum (MyValue) t_values IsNum;
    Return (RC);

    end fn_testvalues;

    Why not?

  • Satellite A350-13 a - function keys does not work

    I have the Satellite A350-13. I installed Windows 7 for 2 weeks.

    The function keys does not work although I have installed the Toshiba value added package, which is responsible for the activation of the function keys.

    What the solution to this problem?

    > Function keys does not work although I have installed the toshiba value added package, which is responsible for the activation of the function keys

    Next to the VAP (value added package) you need to install the Flash Utility card support!
    Card Flash utility support controls the keys FN and not the VAP! But VAP is also needed.

  • Function editor does not support the pointer to the digital type

    Am I missing something or is it true that the CVI function Panel Editor does not support specifying a type parameter as a pointer of type number?

    I see no reason why he wouldn't or shouldn't.  It supports the pointer to char.  And it supports a table name (which, in C, is a pointer to the first element of the array).

    I guess I could use the array form as a pointer, but surely it's confusing when dealing with a simple pointer to a numeric scalar type.

    I am using the function Panel Editor only for the purpose of creating a dictionary of type so I can call functions DLL in VB.  Y at - he know somewhere how CVI types could are mapped to the VB types when you use the type dictionary?   for example, what happens if I use an unsigned int in a function parameter (VB does not support unsigned integers)?

    Menchar

    Hi Menchar,

    To create a pointer to an integer as a parameter to a function panel, you have two different options.

    First of all, all output parameters are defined as the default pointers.  So if you create an output parameter of type "int", he creates a ' int *' parameter.

    Second, if you want it to appear in the entry list, you can create a data type in CVI which will appear at the bottom of the list.  Data types to change your data types, go to the Options"(you must have a function Editor tab open and selected Panel to make this option available).  Enter the name of the type (in this case ' int * ') and click the Add button.  The new "int *" option should now appear at the bottom of the list.

    Third, you can use the array form (int []), but as you say, which can be confusing for other people looking at the code.  Or the other of the two first options are better choices.

    As for your second question, here's a link to a page MSDN showing types in Visual Basic and their representations .NET: http://msdn.microsoft.com/en-us/library/47zceaw7 (VS.80) .aspx.  This allows to make a comparison between VB and ANSI C data types.  For example, to ask on unsigned integers, and this site shows that Visual Basic has an Integer type (-2,147,483,648 through 2,147,483,64) and an unsigned return, UInteger (between 0 and 4 294 967 295).  From what I can tell, VB has signed versions of all its digital representations.  You can then take this with a list of ANSI C data types to convert between the two.  A list of ANSI C data types can be found here: http://www.exforsys.com/tutorials/c-language/c-programming-language-data-types.html

  • XHR call does not work in Edge animate 1.0?

    I am a developer of meteorological applications and worked a lot with Flash and HTML 5. Now, I'm testing the Animate thing on cloud to Adobe.

    Here's my problem:

    I try to call a txt file to my server within a composition Animate. However, I don't have the text of the response.

    On stage, I placed the global variables in order to access it from any scenario of symbol or any other trigger function;

    MY_XHR = new XMLHttpRequest();

    MY_FILE_LOCATION = " " http://myserver.com/myFiles/init_stuff.txt ";

    MY_RESPONSETEXT = "";

    On stage > onCompositionReady I placed this function

    SYM.init_myStuff = function() {}

    MY_XHR.onreadystatechange = function() {}

    If (MY_XHR. ReadyState == 4) {}

    MY_RESPONSETEXT = MY_XHR.responseText;

    Alert (MY_RESPONSETEXT)

    }

    }

    MY_XHR. Open ("Get", MY_FILELOCATION, true);

    MY_XHR. Send();

    }

    In an action of a timeline of symbols, I finally placed

    sym.getComposition () .getStage () .init_myStuff ();

    I get the alert window (so there is no problem with the general idea), but without the expected text.

    Knowing that the problem is always between my ears, I appreciate any idea what the problem is.

    Thanks a lot for your help.

    Piloted it drives me crazy, but finally - solved:

    It was a political matter even. Txt file is located at www.mydomain1.com and the anination is located at www.mydomain2.com. Try to call the mydomain2 mydomain1 does not work.

    When I included the txt file in the folder of www.mydomain2.com animation, everything works fine.

    So be sure to include all external files in the directory on the server of your aninamtion.

    PS: This is also the reason why an iframe added interactions were not possible in FF, Opera and IE9. After you put the HTML code of the pages on the same directory the iframe worked as expected. Like I said: the problem is always between my ears...

  • Satellite U920T - function keys does not work after update to Win 10

    Hello, good morning / evening...

    I use (U920T satellite) and recently updated my Windows 10 Tablet
    but after that, the function keys, volume, brightness, key FN and even the backlight does not work anymore!

    I tried to restore the system and update the driver software but nothing has worked...

    I use these keyboard shortcuts all the time and now it's really hard without them!

    What is the problem? What should I do?

    The problem is that U920T satellite is not listed as Win 10 support unit and, therefore, drivers earn 10 Toshiba and software that controls the FN keys is not released.
    But as far as I know using the FN keys, system of Toshiba and the Support of Flash Card Utility driver must be installed.

    For all Toshiba units win 10 supported, the drivers can be downloaded from this page:
    http://win10upgrade.Toshiba.com/swup...SPX?region=TEG

    Maybe you can try the drivers released for other models of portable Win 10 supported...
    I'm not sure if the software will be compatible with your model of U920T, but its certainly worth a try...

  • Satellite Pro A-153 C50: F11 function key does not work

    The F11 key where I can spend the sound power switch does not work!
    The other keys work correctly.

    Everyone knows how to restore its function?

    Hello

    You use the special function or Standard F1 - F12?
    The special mode of operation allows you to use special features without pressing the FN key.
    This means that if the special function mode, you must press only F11 to turn the sound on and off. In the case of special function mode is off, you must press FN + F11 to turn the sound on and off.

    You can enable or disable the special function mode in:
    Office-> Office help (in the task bar)-> tools & utilities-> function key

    But I wonder if the F11 key works with other software?
    For example: pressing F11 key while using the Internet browser (internet explore) should allow mode full-screen. You can check this?

    Keyboard F11 key is maybe defective and so the sound ON / Off function does not work
