create the header file

Hi, I did a LabVIEW project and created a dll from which should be used in another environment (Visual Studio). I did a VI for each function, I needed and connected the inputs and outputs to the icon as usual. The problem is that the functions declared in the header file for the dll appear to be wrong.

For example, the "CBX_ptite_brune69" in the attached picture VI has without an entrance and an exit (the Bay), but in the header file, I found this:

void __cdecl CBX_ptite_brune69 (double [] noise_array, int32_t len);

This seems to be a function in which there are two entrances (table and len) and which has no exit (Sub).

The same goes fot the other functions of my dll... Why? What I am doing wrong?

Yes you can! You can just it have as value of the 'return' function - you get the data from a variable as an argument to the function (that the DLL then fills with data).

There is a little more information about it here: http://digital.ni.com/public.nsf/allkb/862567530005F09C8625649700587C37

Edit: And here is an example in c ++- http://www.ni.com/example/26518/en/

  • Create the header package or body of several sources in 11 G files?

    I am new to Oracle and although the concept of a package is quite simple (I think than just DLL), it seems terribly cumbersome to have to put all the code for the header or body of a package in a single file. I have a few hundred functions and procedures in the package and it would be nice to be able to split the source into multiple files. I was not able to find a reference to this feature anywhere. Is this possible?

    As an aside, I was going to put all my routines for a particular application in a single package. Is this a common practice, or he normally get broken down more than this?

    Hello

    You want to have hundreds of functions and procedures in the same package?
    A lot of people would create several packages, each with less procedures.

    You can call one script from another. Just put a line containing

    @pk_foo_part_2
    

    anywhere inside the pk_foo_part_1.sql, and every time that you run pk_foo_part_1.sql, then pk_foo_part_2.sql will be executed also.

    If you use two @ signs instead of one, it means that the file is located in the same folder as the appellant.
    In general, I have at least 4 scripts per package:
    (1) a main script, which calls (2), (3) and (4) and grants privileges
    (2) a script to create the head of package
    (3) a script to create the package body
    (4) a script to test the package. He often calls other scripts to test individual procedures, which sometimes rely on other scripts. If there is a limit to how deeply script calls can be nested, I've never met it.

    Only (1) is called a full path name with a single sign. @ all others are called using the @ and the simple name of the script.

  • Error message Microsoft Word "Word could not create the work file. Check the amount of disk space on your startup disk. »

    I have a MacBook Pro, retina 13inch OS X el Capitan Version 10.11.1 with 16 GB of memory. It's brand new and I have recently installed Microsoft Word/Powerpoint etc. a disc that I bought a few years to my previous MacBook. It seems to work very well, but whenever I want to open a word document a message comes up saying "Word could not create the work file. Check the amount of disk space on your startup disk '. However, once I click 'OK' this message disappears and my word file opens without a problem. I have 16 GB of memory on this laptop and it's new I have not reached anywhere near the maximum amount of storage so I'm puzzled as to what this message means. How can I avoid that this message popping up everytime I open Microsoft Word? Any help would be appreciated!

    This has nothing to do with memory - it's the SSD. Word tries to create a temporary file to use as a backup if the program crashes while you are working. First, run the Microsoft Update program to see if there are updates you have missed. Second, Microsoft currently supports only versions 2011 and 2016, so if yours is older, you should consider the upgrade. Thirdly, I suspect that the temporary file is not get created so that you have fewer cancellations (maybe any) and that if the program crashes you have to restore.

  • create the new file using report generation express vi

    Hello

    In my application, I need to write that certain data in spreadsheet Excel. For whom I created an excel template and I used the express vi report generation Toolkit to record appropriate data in the columns of the place. I need a new file created every day by the name of the day and write the data that he rest of the day. I have problems, create the new file using this express vi. I tried to use the low level vi but not able to make properly.

    Join my code and the excel template.

    Help, please.

    Thank you!

    I suspect that your problem is illegal characters (' / ') in your path, certainly it is the case in your original vi. You need to format your path, something like this (underscore instead of a slash stroke):

    Follow the steps below at our own risk.  Set a restore point before doing this. Make a mistake in the registry can have bad results

    In your registry HKEY_CURRENT_USER\Software\Microsoft\Windows\Current Version\Explorer\User Shell Folders\Cache Database Cache data value must be %USERPROFILE%\Local Settings\Temporary Internet Files

    Close all programs. Then in the registry editor, once you get in the folder above, right click on "Cache", make a left-click on "Change", paste in "%USERPROFILE%\Local Settings\Temporary Internet Files" (without the quotes), on the left, click 'Ok' close the editor of the register. Restart the PC.

    This should solve your problem.

    b. navigate to the folder-> "HKEY_CURRENT_USER\Software\Microsoft\Windows\Current Version\Explorer\User Shell Folders\Cache"

    c. check the values of variables [for everything in the "User Shell Folders" folder] - all the variable should have values from '% USERPROFILE%\ '. ». Any variable that is not of this starting point is probably damaged. In my case, all variables corrupt has been a correspondent of "Backup_VariableName". Example: my variable "cache" was damaged when there is a variable called 'backup_cache' with the correct values

    d. change the value of variables corrupt to correct the values. Example of change variable value "cache" in "%USERPROFILE%\Local Settings\Temporary Internet Files" and so on.

    e. close all of Ms Office programs, and turn. The problem should be solved now.

  • Cannot install some programs-can't create the output file in the AppData\Local\Temp user account

    When I try to install a program (.exe) it works winzip Self-extractor, which attempts to create a file in the directory Users\ (myusername) \AppData\Local\Temp\setup.exe

    I just installed windows 7 and had to happen one or two times before that, I think, but I re-uploaded the file and I tried again and it ended up working. Now when I try to install this program (Hava), he says that it is unable to create the output file.

    When I try to go to this place it doesn't even have the AppData folder I have to first create this path or is it a problem with the program? Any help is appreciated. Touch Pro

    Well, that's possible. As WinZip SFX has a small option to overwrite without confirmation box.

    You can move forward with delete the file setup.exe from the Temp folder in the sound is no longer used by any program (where its in the Temp folder)

    You can also try now is, since its opening a WinZIP Self Extracting Archive, you can try manually, and manually specify where to extract the files before you click ok.

    Once you do this, just run setup.exe from the specified location.

    What can be?

    Well, you very probably not a lot of space on the left under/Home.

    You can move to another location that is located on/home/oracle/orInventory the / partitioning of the partition where you probably have more space left if you used the default value.

    For example, as a root user:

    mkdir/U01

    MV/home/oracle/oraInventory/U01

    Update /etc/oraInst.loc and replace

    inventory_loc = / home/oracle/oraInventory

  • How create the CSV file delimited by tabs using ORACLE utl_file?

    How create the CSV file delimited by tabs using ORACLE utl_file? Please provide the code sampl.

    This isn't a problem with Oracle, it is a problem with the way you open the data in Microsoft Excel.

    In Excel, you want (depending on your version may vary slightly)...

    Office 2010...

    1. go in the Ribbon "Data".

    2. click on 'text '.

    3. Locate and select your file, and then click "import."

    4 step 1 of the wizard - choose "Delimited", then click on "next >".

    5. step 2 of the wizard - choose "Tab" as the delimiter and click on "next >".

    6. step 3 of the wizard - define types of column as needed (if necessary) and click on "Finish".

    7. check where you want the data in the worksheet.

    Data is loading now in single cells as you expect.

    If you just double-click the CSV, Excel is apparently assuming that it will be separated by commas and does not recognize tabs as separators, unlike when you rename the file with a .xls extension where it examines the file, complains that it is not a content .xls and asks you to confirm that you want to continue loading and then intelligently recognizes the tabs and the format for you.

    As I said, not a problem with Oracle, just a problem with the MS Excel software.
