How to Use DLL correctly in LV ?

I'm trying to use a DLL from former S/W written in C++.
The DLL is using other DLLs.
The LV doesn't find the other DLLs although they are in the same directory .
Can you direct me how to pass this issue ?
Thanks
Edo

You are using the DLL node correctly, but the problem is that it is
Windows looking for the supplementary DLLs, and it has a pretty fixed
set of places it looks. Putting the supplementary DLLs in the Windows
System directory definitely works -- this is why so many apps just dump
them in there. I think that setting your working directory to the
location of the DLLs will also work, but not real sure about that.

How to use dll in Labview ?

I compile this code to dll file with VC++2010 filename is test_dll.dll .
#include "stdafx.h"
#include <iostream>
#include <Windows.h>
using namespace std;
int main(int a){
cout << "Test dll...............\n";
return a;
After that, I put Call Library Function node in editor and double click Call Library Function node. I browse test_dll.dll into Library name or path and set function prototype to int32_t main(int32_t a); but it show error Call Library Function Node 'test_dll.dll:main':function not found in libraly. How to use dll in Labview ? And I have more question is what is differrent from Tools -> Import -> Shared Library(.dll) and use Call Library Function node.
Solved!
Go to Solution.

The issue you are having is that LabVIEW is not capable of using C++ DLLs directly. It only handles C DLLs. This does not mean that if you you cannot use the DLL if it's compiled with the C++ compiler as opposed to the C compiler. Rather, it means that you must take extra steps in order to use it from LabVIEW. The primary issue is that of name mangling or adornment. This is discussed here: http://zone.ni.com/devzone/cda/tut/p/id/4877. Basically you need to prepend extern "C" in front of your prototypes in your header files. I would also suggest reviewing this article: https://decibel.ni.com/content/docs/DOC-14564.

How to use .dll compiled in Delphi in Java?

Can anyone provide me information how to use .dll compiled in Delphi in Java? The .dll Delphi program may be non-OOP program.

Hi
If You want to write anything in PASCAL then simply write JNI code in C++ and call functions from this DELPHI DLL, but remember about changing the order of parameters etc when You call it. I had exactly the same problem, but it is possible, and we succeed.
You will need exact description of input parameters required by PASCAL functions and of output parameters. Then construct in C++ objects wchich looks in memory exacly the same as they will look if You will be using PASCAL. Then PASCAL function will interprete this area in memory as known structure and will run.

How to use dll function in JDeveloper?

I want to use function in dll to develope my application,but
I can't find how to do that in the JDeveloper document.

You have to use the Java Native Interface to use dlls. The JNI
tutorial at http://java.sun.com/docs/books/tutorial/native1.1/
walks you through the basics and provides a sample too.
Hope this helps.

"Only Get Delta Once" - How to use this correctly?

Hi folks,
we are currently facing the following situation:
We have a data source only being able to deliver full update.
That's why we proceed as follows:
1.) Full-Load with Infopackage to PSA
2.) Delta-Load with DTP from PSA to first-level-DSO (write-optimized)
3.) Delta-Load with DTP from first-level-DSO to second-level-DSO (standard-DSO). As the activation aggregates all duplicate entries, we are therefore able to deliver a delta to all following data targets (e.g. infocubes)
What we are now wondering about how to use the flag "Only Get Delta Once" which is available in all Delta-DTPs. The help explains it should be used when creating snapshot-scenarios like ours as each request is only delivered once, even if it gets deleted in the data target.
But what other benefit would we have when setting this flag? As I mentioned, the snapshot-scenario also works without this flag...
Could anyone perhaps provide me some more details about this flag and where it should be used?
Thanks & regards
bivision

Hi,
If you select the option 'Only get delta once', then every request in the PSA will only be loaded into the Data target once. For example. If you load a full request into the PSA through an InfoPackage and then load it to the Cube. In a snapshot scenario, when the new full load comes to the PSA you will need to delete the previous request from the cube before loading the new request.
But if you delete the previous request from the cube, and not from the PSA - and if you haven't checked the 'Only get delta once' flag, when you execute the DTP, it will load both previous and the new requests from the PSA to the cube. In order to avoid this you have 2 options:
1. You can delete a request from the PSA after every successful load into the Cube OR
2. You can check the 'Only get delta once' flag in the DTP so that it won't load any request it has loaded into the cubes previously even if it was deleted from the cube.
Using the second option de-couples the PSA maintenance from your regular data loading and also saves you an additional step of deleting the PSA request in your process chain.

How to use DLL written in VB in JSP

I have a .dll written in Visual Basic. I want to use that dll in JSP. can anyone tell me is it possible? if yes than how.
please rely with a complete example.
Thanks in advance
Lalit

I thought JNI required that it be a C++ DLL.
Maybe you could wrap that DLL as a COM object and used a COM bridge to talk to it.
"please rely with a complete example." - I don't have one, but if I did I'd ask you to please reply with a lot of USD. This isn't an on-demand free consultancy, you know.

How to use DLL in JSP?

          Hello, all,
          I wrote a program to check the user authentication by call Windows's cryptography
          functions. I have generated a DLL file,
          and have put it in the C:\bea\jdk131_03\jre\bin. But my jsp
          page seems ignoring the java code to call the function in the
          DLL. I am not sure what should be imported at the head of the
          jsp file. Would somebody kindly help me out? Thanks a lot!!!
          My jsp code is here:
          <%@ page import="java.sql.Connection"%>
          <html>
          <head>
          <title>
          Jsp1
          </title>
          </head>
          <body>
          <h1>
          JBuilder Generated JSP
          </h1>
          <%
          try{
          if(Ntauth.authenticate("gecorg", "almond", "1025"))
          out.println("Valid user credenticals");
          else
          out.println("Invalid user credenticals");
          }catch(Exception e)
          out.println(e);
          %>
          </body>
          </html>


          One of my friend helped me to generate a new dll,
          just changed the package name. Then it works. I don't
          know why. But anyway, it works. Thanks everybody for
          your attention.

How to use BAPI_INTERFACE_GETDOCU correctly?

Folks,
I need to get the list of parameters and their definitions for a specified BAPI. It appears I need to call BAPI_INTERFACE_GETDOCU to get this information. However, there is not enough information on how to call the function correctly. The following .NET code, for example, returns an error that objname or objtype is not specified.
p.Bapi_Interface_Getdocu(null,   null,   null, "BAPI_MATERIAL_SAVEDATA", null, null, null, null, out ret2, ref tbl);
Can someone please help me on calling this function correctly?
Thank you in advance for your help.
Regards,
Peter

Hello Peter
The documentation of BAPI_INTERFACE_GETDOCU is quite verbose:
FU BAPI_INTERFACE_GETDOCU
Short Text
     Read BAPI Interface Documentation
Functionality
     This method reads the interface documentation for a BAPI.
     The method enables you to read out and make available to developers the
     information they need to implement BAPIs correctly.
     The parameters of this method delimit the documentation to be displayed.
     With these parameters you can specify whether you want to display the
     documentation on a business object, method, parameter or field. The BAPI
     interface documentation below can be accessed with this method:
     o   The documentation on the business object, if one of the two
         parameters OBJTYPE or OBJNAME contains a value and the parameters
         METHOD, PARAMETER and FIELD are BLANK.
     o   The documentation on the method, if one of the two parameters
         OBJTYPE or OBJNAME contains a value and the method name is specified
         in the parameter METHOD. The parameters PARAMETER and FIELD must
         also be BLANK.
     o   The docmentation on the parameter, if the parameter name is also
         transferred in the field PARAMETER.
     o   The field name, if the field name is also transferred in the
         parameter FIELD. This is only possible, if a structure has been used
         for the parameter.
Example
     In this example the documentaion on the BAPI "Employee.GetList" is
     retrieved without the parameter documentation. It is displayed in
     English (EN) in RTF text format.
     Import Parameter    Value
     OBJTYPE
     OBJNAME             "Employee"
     METHOD              "GetList"
     PARAMETER
     FIELD
     LANGUAGE            "EN"
     TEXTFORMAT          "RTF"
Notes
     Messages are returned in the parameter RETURN. This parameter
     documentation contains the return codes and their descriptions.
Parameters
     OBJTYPE
     OBJNAME
     METHOD
     PARAMETER
     FIELD
     LANGUAGE
     TEXTFORMAT
     LINKPATTERN
     RETURN
     TEXT
Exceptions
Function Group
     BATG
I did not find the BAPI immediately in the BOR (transaction SWO1) therefore I searched table SWOTLV with VERB = 'SAVEDATA'. And here I found the BAPI belonging to business object BUS1001006.
To retrieve data from BAPI_INTERFACE_GETDOCU use the following IMPORTING parameter:
OBJTYPE = 'BUS1001006'
LANGUAGE = 'EN'
TEXTFORMAT = 'RTF'
I tried to call the BAPI using
OBJNAME = 'StandardMaterial'
OBJTYPE = 'SaveData'
but here I did not retrieve any data.
I just tried another combination of IMPORTING parameter:
OBJNAME = 'StandardMaterial'     " no OBJTYPE !!!
It worked.
Other textformats are:
SCR     SAPscript
ASC     ASCII
RTF     Rich text format
HTM     HTML

Trying to get into the app store and it asks for my password. The problem is that it is showing an Apple ID I don't use ghosted in. I can't figure out how to use my correct ID.

Trying to get into the App Store to update some apss. It asks for my password but the problem is that it is showing ghosted an Apple ID I don't use. Can't figure out how to fix it.

You installed a hacked app, originally from the Mac App Store. It contains the receipt for a different app, downloaded using an account that you don't control. You need to identify and remove the hacked app.
Important: The app you need to remove is not necessarily the one named in the App Store alert. For example, if the App Store says you need to update "Twitter," the hacked app may be "Angry Birds" or something else entirely. Don't make any assumptions about which app you're looking for. To find it, you have to carry out a systematic search.
Triple-click anywhere in the line of text below on this page to select it:
kMDItemAppStoreHasReceipt=1
Copy the selected text to the Clipboard by pressing the key combination command-C.
In the Finder, press command-F to open a search window, or select
File ▹ Find
from the menu bar. In the search window, select
Search: This Mac
from the row of tokens below the toolbar. Below that is a popup menu initially showing Kind. From that menu, select Other...
A sheet will drop down. In that sheet, select Raw Query and click OK or press return.
Now there will be a text box to the right of popup menu. Click in that box and paste (command-V).
The search window will show all the App Store products you've installed. Compare those search results with the list of your purchases from the App Store. To see the complete list, you may need to unhide hidden purchases. If any apps were download from the App Store using other Apple ID accounts that you control, sign in to the store under each of those ID's and check the purchases.
At least one of the items listed in the search window is not among your purchases in the App Store. Move each such item to the Trash. You may be prompted for your administrator password. Empty the Trash.

How to use dll's(Functions) in java ?

Hi
I want to use the windows : shell32.dll. The declaration is as follows:
Declare Function ShellExecute Lib "shell32.dll" Alias "ShellExecuteA" ( _
     ByVal hwnd As Long, _
     ByVal lpOperation As String, _
     ByVal lpFile As String, _
     ByVal lpParameters As String, _
     ByVal lpDirectory As String, _
     ByVal nShowCmd As Long) As Long
I load the library via System.loadLibrary("shell32") and define the native methods(in java code):
public native long ShellExecute(
long hwnd, String lpOperation, String lpFile,
          String lpParameters, String lpDrectory, long nShowCmd);
but i get a: java.lang.UnsatisfiedLinkError: ShellExecute. Whats wrong ? For long hwnd i used "0" for the first time, but this shouldn't be the problem. Any idea ?
hte problem i have is to execute a very difficult programm. this need a system(windows) shell to run. so i try to start it with the shell32.dll. in VisualBasic i found my aim using this topic, but it doesn't run in java.
thanks for help.

How to use DLL files in java?

hi!
i am working on hardware based java programming. the drivers which i have are in dll format. the manufacturers dont have a java based driver api's for the hardware. i want to invoke the dll file using a bridge between windows invironment and jvm invironment. more over i am not preferring to use native interface interface and c program to tackle this problem.
is there a way out?

Is it a COM dll? You could use JACOB. If it's not COM, there's also JNA which as I understand it, is simpler than JNI, although I've never used it

How to use DLL file

if i have a DLL file and i want to use them in my program
is it possible to import them for example
import Node.DLL
or what , please tell me it's important for me

You can use the DLL file by using System.loadLibrary().
To use the functions in the DLL, you have to provide a JNI interface to it.
Here's a good link to a tutorial.
