the pointer to int as a parameter in the dll, but the value of parameter variation doesnot

Hello, I have a function in the dll as void set(int * a) {(* a) = 99 ;}}

And I connect an int32 to the dll. But when I run the vi, the Int32 value does not change.

As the picture below:

You connected control DLL parameter. This means that the value of the command is passed to the DLL... and finito! You must connect an indicator on the right side of the DLL parameter to see the value returned by the DLL.

  • CVI 2013 SP1 - function calls repeated with pointer on a variable array parameter causes a shift of the index

    I have some functions will be pointers as parameter and CVI 2012 SP1, they work as before without problems but with CVI 2013 SP1 they are now incorrect.

    Here the description of what is happening - I found a cure, but a duty adopt the old code and I think it's clear that nobody don't "captures" all lines in a 'big old code' which are affected (maybe):

    I have functions

    'function_XYZ(int *p_paraArr) '.

    with 'p_paraArr' as pointers on a table (int).

    Suppose I have another function

    "fct_TOP (void)".

    where is a local array variable which is inizialized by

    "int TheArray [25] = {0};

    and inside of this "TOP"-function-body I call a function ".

    "function_XYZ (TheArray).

    There are no complains of the compiler (CVI 2012 or 2013) and the code works (but the CVI 2013 only once!).

    But if I put 'fct_TOP' loop I have a lag in the "TheArray' -memory.  (The loop surrounds the function "TOP"! "")

    This means that the result "TheArray" obtained from "function_XYZ (TheArray)" starts at index '1' not on the index '0' - as the first time that the function "function_XYZ (TheArray)" was performed. ".

    The solution is:

    I only replaced

    "function_XYZ (TheArray)" (<1>)

    by

    "function_XYZ (&(TheArray[0]))" (<2>)

    overall the program now works every time (in the whole loop)-the first time (in the loop).

    In the second version (<2>) everything is necessary to "work well":

    The '&' and parentheses "(...)", which contains the element that may be designated by the '& '.

    And I hope that you believe me: I've tested several times, it was only "little" change that solved the problem.

    So it seems that the ICB 2013 (SP1) is a kind of internal offset index by a repeated execution of the

    "function_XYZ (TheArray).

    but I don't know how or why but I see in debug mode by observing the expected against the values in the table received!

    At the first time the (implicit) internal index of 'TheArray' is '0', but the following times (during the execution of the loop) the internal index passes to '1' (seen in the debugger because that all the expected values were shiftet like that!).

    So there's an explicit index in the table ("function_XYZ (&(TheArray[0]))") necessary to make the first time of this clear code execution.

    There are some good improvements in 2013 CVI (SP1) and I like this environment more than the 2012 version - but:

    There are other "changes" also, in the compiler (or linker...?) that are more rigid than "in ancient times.

    The problem of this kind of error is always the 'old code '!

    It is expected of such behavior.

    The compiler/linker do not complain (a complaint would be good!) writing but he made this mistake (in a loop).

    By the way: my 'compilation Options' are set to 'Extended' (without change in the "..." ("- button - Options) and that all of the boxes, except the" OpenMP_support "-box are checked!"» So I think that I put the very rigid compiler - maybe there are some «...» ' - button - settings to get rid of this problem, but I have not found them/it.

    My request:

    -Check the stiffer compiler by the need of an explicit index

    - or switch to the 'old' behavior with "function_XYZ (TheArray)" always refers to implicit index '0' of the element "TheArray". "."

    Thank you for your messages, comments and suggestions.

    -As I wrote before - maybe it's the style of programming or error"self made"... maybe...
    .. But if I replace 'function_XYZ (TheArray)' by "function_XYZ (&(TheArray[0]))" and
    then it works... Why so and not, if bothe the same? ...

    But as long as I do not post sample code, nobody is going to accept - I accept it. So consider this post more as an allusion to the fact that of the LW/CVI 2012-2013 LW/CVI more changed than just the LW - GUI or certain features: the compiler changed its 'way to'... or almost.

    For this problem, I think that I will use the solution 'use no implicit and explicit pointers'.

  • Please show or ask how to create the value of arrayOfValues of setValuesAtTimes parameter?

    Hello AEScriptComm,

    I have a few small scripts that use the method setValueAtTime successfully placing a keyframe on the existing layers of maskPath, but as you can see in the scripts below, results of setValueSatTimeS errors using IE: "Array is not of the correct type", "value is not an array" or "Null is not an object", depending on ,...

    (A) what variable is used as the value of parameter IE:

    .maskPath;

    . maskPath.value;

    . maskPath.value.vertices

    (B) what kind of table is used as the parameter value as in:

    var addTheseKeys = new Array ((1,2,3,4);    (as a parameter of the time)...

    (with either)

    var keyValues = new Array([10,10],[100,100],[15,50],[100,120]);             ...." ]) "

    (GOLD)

    var keyValues = [[10.10], [100 100], [15.50], [100 120]];                               ... (Array of arrays? RE: " ]] " )

    I just read a 'push' of the values in a table may be necessary?, but I was hoping someone who knew setValuesAtTimes could show it please...

    1) .. How to create the value of arrayOfValues of setValuesAtTimes parameter?

    1 (a): WORK setValueAtTime script...

    App.Project.Item (1) .layer (1).property("Masks").property ("mask 1");

    var app.project.item = myProperty (1) .layer (1) .mask (1) .maskPath;

    myShape = app.project.item (1) .layer (1) .mask (1).maskPath.value;

    myProperty.setValueAtTime(1.0,myShape);

    1 (b): If there is no script setValuesAtTimes...

    prop1 = app.project.item var (1) .layer (1).property("ADBE_Transform_Group").property ("ADBE Position");

    var fourKeys = 4;

    var addTheseKeys = new Array (1,2,3,4),

    var keyValues = new Array (10, [10], [100 100], [15.50], [100 120]);

    myProperty.setValuesAtTimes (keyValues, addTheseKeys);

    app.beginUndoGroup ("Keys");

    ~ for (var k = 0; k < fourKeys; k ++)

    //~ {

    ~ prop1.setValueAtTime (keyValues [k], addTheseKeys [k]);

    //~ }

    myProperty.setValuesAtTimes (keyValues, addTheseKeys);

    app.endUndoGroup ();

    .. Thanks for any advise\suggestions,

    J

    (A). maskPath.value; It's always a Shape(). (maskPath is a property, not of a shape on its own, and maskPath.value.vertices is only a part of the shape data).

    (B) nothing of what you propose... that is why your failed script fails.

    var keyValues = new Array([10,10],[100,100],[15,50],[100,120]); and

    var keyValues = [[10.10], [100 100], [15.50], [100 120]]; are just as good as arrays of points, the only thing is that keyValues are arrays of objects Shape().

    Read the guide and script for how to report a form of this post (just wrote it...): http://forums.adobe.com/thread/1419866?tstart=0

    Your keyValues array should look like this: [keyValues0, keyValues1, keyValues2, keyValues3], where each entry is a Shape().

  • the procedure entry point GetFinalPathNameByHandleW could not be found in KERNEL32.dll dynamic link library

    Hello

    While trying to install a program, I see the following on the screen error message:

    The procedure entry point GetFinalPathNameByHandleW could not be found in KERNEL32.dll dynamic link library

    The I set him, is a Windows XP 32-bit environment.

    The I am installing, is a program, created by my own company, using a 32-bit self-extracting installer, which is also created by my own business using InstallAnywhere Flexera software.

    No changes were made on the environment of the installers.

    No change seems is done on the environment for creating installation programs (where the self-extracting installer is created): I checked the monitor of reliability/Action Center / Control Panel and no entries are present between a job and an installer without work.

    The file 'KERNEL32.dll' is mentioned in the error message, I checked his date of change, which is 11/30/2012, this should not be the cause of the problem either.

    Witnin the self-extracting installation program, a few changes were found, those who are considered at the moment, but there is no indication or not those who are causing the error message I see here.

    Does anyone have an idea what may cause the error message mentioned and how to cope?

    Thank you

    Dominique

    These types of error messages mean that the program is looking "inside" the file specified (in this case kernel32.dll) try to find a function/procedure to run called "GetFinalPathNameByHandleW" and find do not.

    The program calls the non-existent function badly or the library file is not in there.  Things do not match somewhere.

    A DLL is a library of dynamic links and files as kernel32.dll are sometimes just a bunch of procedures/functions/subroutines and all located in a single, portable file.

    In a primitive way, you can use a text editor to open the kernel32.dll file (make a copy if it your desire) and search for a string "GetFinalPathNameByHandleW" and you will not find.

    You can even search for "GetFinal", and you won't find it in the XP kernel32.dll file:

    But if you do the same thing on a Windows 7 + kernel32.dll you 'll find:

    If your program calls a function inside a DLL, but this feature does not exist in the Windows XP's kernel32.dll file.

    I think that GetFinalPathNameByHandleW was introduced in Windows Vista, so now here you would be fine.

    If who wrote your program is that it works on XP, they need to stick to the functions that are part of XP and GetFinalPathNameByHandleW isn't here, where the error.

    I'm quite new to forms, I have 1 requirement, I have 2 points (dot, dot XY) on the forms and the point x can be set to LOV or the user can also enter the value without LOV.

    The condition is that if the point x has received value = '03' part must be active, editable, and if the scope of the element X is set to any other value (or null), the item field there should be delivered to null, made inactive, cannot be changed.

    I'm really grateful if someone to guide me. Thank you

    Concerning

    Muzz


    Dear MUZZ

    in forms, if you disable or invisible something, its NAVIGABLE, INSERT_ALLOWED, UPDATE_ALLOWED properties were also defined as FALSE. So if you allow an element, you must set the other properties to True.

    So, your code will be

    IF :. = '03' THEN
      SET_ITEM_PROPERTY('.', ENABLED, PROPERTY_TRUE);
      SET_ITEM_PROPERTY('.', NAVIGABLE, PROPERTY_TRUE);
      SET_ITEM_PROPERTY('.', INSERT_ALLOWED, PROPERTY_TRUE);

      ELSE
      :. := NULL;
      SET_ITEM_PROPERTY('.', ENABLED, PROPERTY_FALSE);

    Hi guys,.

    I want a global variable (application point) whose value will be set to start when a user logs on to the application. The value will be retrieved from the database by using a sql query. I don't exactly know the syntax to set the value of the point of application in the application process. Also, I want to know what type of enforcement process should I use to set the value of the point of application, when a user starts a session. The value of the point of application varies from one user to the user.

    Help, please.

    I use apex 4.2

    Kind regards

    You can use the application element as a link with his name. That is to say. your point of application is named G_MY_APPLICATION_ITEM, then you can / set of access using: G_MY_APPLICATION_ITEM.

    For example

    BEGIN

    -assign as a variable

    : G_MY_APPLICATION_ITEM: = 'LARRY ';

    --

    -use in a SQL statement

    SELECT WHATEVER_COLUMN

    IN: G_MY_APPLICATION_ITEM
