How can i use dlls for running rtc3?

how can i use the dll libraries to use for the rtc3 software?

How? You provide almost no useful information.
What is rtc3?
Why do you think you have to use DLLs?
What did you try so far that hasn't worked?
What is it you want to accomplish?
You see what you ask here is just about the same as if someone would ask you to tell them what screw he needs to fix his car.

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.

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.

Using DLL functions created with LabVIEW 6i in CVI 4.0.1

Structure using dll

Hello all,
does anyone know how to operate on the structure in LABVIEW?
I need to develope the interface in LabVIEW to call the external code WinMCL Plus (developed by GSI Lumonics),
but I do not know how to operate on the global parameter sets. I try to use DLL to call the function
"MC_set _ParamSet" (see below), but I cannot point to the parameter sets in the "Call Library Function".
MC_set_ParamSet
//       Routine Description:
//                     Set the global DLL Parameter set at Params[Index] to
//                     the values stored in *p
//         Parameters:
//                        Index - Parameter set index.
//                        *p             - Pointer to the parameters to set.
//          Return Value:
//                        WMCL_OPERATION_OK or WMCL_OPERATION_FAILED.
//         Comments:
WINMCL32_SPEC unsigned long_stdcall MC_set_ParamSet(int Index, PSET *p);
Any help would be greatly appreciated. Thanks in advance for your help.

Gennady,
Check out this link to get some more info...

Near the bottom of this link it has the section ;

It looks like your best solution would be to create a wrapper that splits up this structure into more basic elements for labview. Hope this helps.

Collecting data from hardware using dll

Firstly I d like to say hello, im the very beginier to labview thus I appeal for some patience.
There were many threads dealing with that issue, I tried to get information from each one of them.
and I posted this mesaage in order to make sure if i `d got it well.
Well I ve got hardware and want to gather data from it, (its not array but 3 (variables?) and of course it has its own dll.
What am i supposed to do is?:
1.write other dll (VS) and there is asynchronous callback to device to get its position just like in exec aplication.
2. USe PostLVUserEvent() to make parameters familiar to labview (in dll)?
is that correct way of thinking ?
I dont have problems with using dll in labview, but I dont know much about how asyncrhnous callbacks works with dll
I hope its all clear.
I know the all answers are here but I d like to summarize it, especially that I could miss something.

There is dll (api?) provided by drivers(generally speakin) with all functions needed and documentaion, and second dll written by me with imported this finctions , which actually isnt a wrapper, but only c dll.
Code was rewritten and divided (compared to previous one) to 3 functions in order to avoid loop... and there is no callback anymore , ...... but called from labview one by one these functions are running very slowly - otherwise from the exec application that I made to test dll. I hope its understable enough .
I think documentaion isnt necesary.

hdStopScheduler();
hdUnschedule(gCallbackHandle);
hdDisableDevice( hdInitDevice(HD_DEFAULT_DEVICE));
I used pointers with simple functions dll like adding etc. before and it worked fine.
I admit I dont exactly get callbacks. Its seems I can manage without them now, but I`m aware that during more complicated 'operations' it would be much harder. Now it works in labview but very slowly...

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

Issue in using DLLs from a VC++ 6.0 MFC application

Hi,
I am using Labview 7.1 for creating VIs.I have created DLLs for accessing
these
VIs from a VC++ application. The VC++ 6.0 project is created using MFC app
wizard. When I try to execute the VC++ project in Debug configuration it
works
fine. When I try to execute the same in release configuration I get an
error as
shown in the attachment.

Hi Mukund!
I found this response on another forum thread that looked like it could help you out:
==============================================================
MSVC++ error (system error 998)
This is actually a Microsoft issue. It has something to do with static and
dynamic linking of the MFC DLL. Our R&D engineers have verified this with projects created with no LabVIEW code at all (that is why we believe it to be solely a Microsoft issue). There are three options at this time:
1. Link with the DLL form of MFC.
2. Do not link with the .lib from the LV DLL, instead use LoadLibrary and GetProcAddress to dynamically load the DLL and call the function.
3. Use the VC delayload feature to make the LV DLL not get loaded until the first call is made into it. See VC help on "delayload" for information on setting this up.

Using dll in a procedure

Hi All !
Is there some way to use a dll file in the oracle stored procedure?
Any Oracle supplied Package?
and can i have a site for the material regarding "Oracle Supplied PL/SQL Packages Reference"

To phrase it more clearly. To implement such a logic is probably many times more complex then simply reprogramming your vb.net logic in pl/sql. Or changing your logic flow from client to server, instead of from server to client (as you want it to be).
However here are some documents to start reading.

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.
