How to call VB dlls in java

Hi
I created one component in vb, where this component got 3 methods. and created dll also, when iam trying to use these dlls in java. it showing error, is there any method to call the vb dlls in java(native method), if s pls help me to solve these problem.

hi, all
I writed a vb dll, It have three publice sub and one preporty,
I use html <object> attribute to declare this dll and call its methods and perporty in html file, everything is ok.the source code as following:
<body>
<OBJECT declare id="repExport" classid="clsid:0487D845-0DAD-46D0-9559-FADEC117C2B9">
<param name="Exportfile" value="peiru">
</OBJECT>
<script language="vbscript">
repExport.Exportfile="peiruyt"
repExport.CrystalConnect()
repExport.PassParameterRtp()
repExport.reportexport()
</script>
Because i need get parameter from other web page , and i use weblogic 6.1 server, so i need change file type from html to jsp , But even if I just change the file extension from html to jsp, don't change any content in this file.
then jsp cannot work, error message is "object don't support 'repExport.Exportfile' property", actual it don't support all three functions and a property
Can anyone provide any help?
thanks

How to call the .dll use Jave

hello,
I will to call a .dll file in java
which function or API can do that ?
if someone knows , please tell me .
thanks

You must define "native" methods in java. The native methods allow you to call out of java into C programs (dll's on Windows, so's on unix.)
There is a java tutorial on native methods. Look for the buzzwords JNI, which is Java Native Interface.

Is it possible to call VB dll in Java

Is it possible to call VB dll in Java?
If yes then How?

If you mean VB6 than you can call VB Module like a COM object with any Java-COM bridge.
VB.NET could be called with my Object-Oriented JNI for .NET 1.1/2.0:

How to call the DLL writing in Vb6.0 from testsatnd?

Hi,
I want to call a dll writting in VB6.0 from teststand. But as i see from the "Step Setting" in teststand, only the C/C++ Dll can be selected in the "adapter" type. I try to use this one as my adapter to call my VB6.0 dll, in result, there is no function can be seen in the "function" tab in teststand.Anyone know how to call the DLL writing in Vb6.0?
Solved!
Go to Solution.

Hi Ivan,
Just to be sure that your DLL is not wrong
you have check if all functions are well and present.
There is tool called "Dependency Walker" You can download it at http://dependencywalker.com/ .
With it you can look "inside" your dll
If you will see your functions there, you will see them (in my case !!always!!) in TestStand, too.
Hope this helps

How to call gnuplot command from java

Hi there,
In our course, we are required to develop an GUI for gnuplot. In case you don't know about gnuplot, it's a plotting program and has lots of command. We want to use java and swing, but now we don't know how to call gnuplot command from java, or how to execute a shell command(script) from java.
By the way, since we need read in files with several columns of data and allow user to select a column, we want to use JTable. Is that reasonable?
Thanks a lot for any suggestions!
Jack

Hi, there:
Will using JTable add much overhead? I may have to use several JTables and switch among them. I can add scroll bar to or edit JTables, right?
BTW, do you have experience about gnuplot? Can I find the command tree of gnuplot somewhere? Or do you know a better place to post question about gnuplot? unix/linux group, maybe.
Thanks,
Jack
P.S. Would you guys answer my question after I use up my duke dollars? :- )

How to call Jakarta Ant via JAVA?

Hi.
My application has a new menu. This menu creates a build.xml Ant file.
Now, when this menu is invoked , its action should call
Jakarta Ant, after creating the xml file, so that the build.xml will
do what is necessary.
How can I do it? That is, how to call the Ant via java?
Is there any way to use an Ant object?
Thanks?
Rodrigo Pimenta Carvalho.

There is a slight problem in that
PorjectHelper.configureProject is deprecated, but
that is what Main calls...maybe someone else will
complete this thread with an alternative call.The javadoc recommends using the non static method parse() instead. This is available by implementing class ProjectHelperImpl. An alternative to the code above might look like this:
        Project ant = new Project();
        ProjectHelper helper = new ProjectHelperImpl();
        ant.init();
        helper.parse(ant, new File("build.xml"));
        ant.executeTarget("clean");you might also want to add a logger so you can see the output of events generated by ant. The DefaultLogger class would be used like this. Simply add the code before you call the ant.init().
        DefaultLogger log = new DefaultLogger();
        log.setErrorPrintStream(System.err);
        log.setOutputPrintStream(System.out);
        log.setMessageOutputLevel(Project.MSG_INFO);
        ant.addBuildListener(log);

How to call LabVIEW dll from ATL COM dll

I have tried to call simple LabVIEW 8.6 Dll from win32 test application, class Library.
I have include LabVIEW generated SharedLib.h file and SharedLib.lib file in the test application which I created as simple win32 console project and also from win32 class Library. I was sucessfully able to call my LabVIEW dll funtion.
But when I create ATL COM project and try to add SharedLib.h file and SharedLib.lib file I used to get following erors
Error 1 error C2733: second C linkage of overloaded function 'StrCatW' not allowed d:\program files\national instruments\labview 8.6\cintools\extcode.h 463
Error 2 error C2733: second C linkage of overloaded function 'StrCpyW' not allowed d:\program files\national instruments\labview 8.6\cintools\extcode.h 464
Error 3 error C2733: second C linkage of overloaded function 'StrCpyNW' not allowed d:\program files\national instruments\labview 8.6\cintools\extcode.h 465
Error 4 error C2733: second C linkage of overloaded function 'StrCmpW' not allowed d:\program files\national instruments\labview 8.6\cintools\extcode.h 466
Error 5 error C2733: second C linkage of overloaded function 'StrCmpNW' not allowed d:\program files\national instruments\labview 8.6\cintools\extcode.h 467
these many errors.
Will some one explain me how to call LabVIEW dll from ATL COM dll.
Thanks & Regards,
Jay

I also had this problem. My application is unicode-aware, but I was attempting to link it to a library with primitive C-string arguments. You could dynamically load the DLL as suggested (more work), modify the header files (really not recommended), or if you are feeling lucky you could try fooling the compiler, as I was successfully able to do in Visual Studio 2010, by steering the preprocessor around those functions (assuming you're not using them, of course -- otherwise this probably wouldn't work):
// prepare for NI extcode.h inclusion. avoid linker errors for this project.
#define StrCatW(a,b)     IgnoreLinkError_StrCatW(a,b);
#define StrCpyW(a,b)     IgnoreLinkError_StrCpyW(a,b);
#define StrCpyNW(a,b,c) IgnoreLinkError_StrCpyNW(a,b,c);
#define StrCmpW(a,b)     IgnoreLinkError_StrCmpW(a,b);
#define StrCmpNW(a,b,c) IgnoreLinkError_StrCmpNW(a,b,c);
// header file for my LabView-built DLL (ASCII single-byte character arguments)
#include <MyLibraryHeader.h>
// clean up afterwards, put things back to 'normal'
#undef StrCatW
#undef StrCpyW
#undef StrCpyNW
#undef StrCmpW
#undef StrCmpNW

How to call a dll which has one VISA name as input

Hi there,
The Labview application builder can generate a dll file from a vi which is a simple serial comunication program using VISA name as one control.
The problem is how to call the dll file in Labview which has a VISA name as INPUT?
Thanks!
George

I would suggest modifying the LabVIEW VI so that the input is a string control instead of a visa control. The LabVIEW application will work the same and there is no need for any casting. All visa VIs can take a string as an input. Then when you recreate the dll make the input a string. Then you can easily pass a string to the dll from any API.

How to call the DLL functions through Java

Hello,
I have already got a VC++ generated DLL. It has serveral functionalities. I need to call those functions from my Java Application. Now i know that it can be possible only through writing Java JNI Interfaces.
Everywhere i only see they give an example where in they tell to create an DLL. Now how do i will call if an DLL is ready and exists.
If anyone can give an example then it will be very helpful to me. Please mail me at [email protected] .
Thank you
vvpatro

You can't call functions in an arbitary DLL form Java. You need to use JNI to produce a 'wrapper' DLL that maps Java methods to the methods in the target DLL. The purpose of the wrapper is to allow type conversion between Java types and C/C++ types. The complexity of this task depends largely on the types used in th target DLL. If the targer DLL uses only primitive types such as char, byte, int, long, string, the translation is simple and the wrapper DLL will be 'thin'. If however, the target DLL passes arrays and objects, or employs callbacks, these more work to do, and the wrapper will be correspondingly 'thicker'.
Hope this helps.

How to call c++ code from java

i have a third party dll written in c++. I want to call its methods in java. I searched web and found that I have to use JNI for this. I have seen examples on web writing c++ code and then using it from java through JNI, but can anybody please point to me the example where i have a predefined library or dll in c++ and i have to call it in java. I think that I may have to declare methods in library as native in java and then write a wrapper implementation (dll) in c++ which actually calls the library or dll functions. But, then how will I call methods of dll from my wrapper code.
Any examples, please point
Regards,
Farooq

There's a JNI forum here that may be a better place for this question; though given the general nature of the question, I suspect that they'll refer you to a tutorial. good luck.

How to create a dll in Java?

I have written some code in Java to perform a certain function.
How can I create a dll for this code? Would I be able to call this dll from any platform?

Let me rephrase the question. I would like to create a dll for code that is written in Java.
Can you please tell me the procedure to do that?
I want to be able to call this dll from .Net framework or any other application. I found examples online to do the opposite using JNI.

How to call Fortran .dll file that using other library files?

Hi,
I am trying to do some arkward tasks using LabView, and I am desperately need help....
A little bit background:
1. My co-worker has some code written in Fortran, where he called other libraries (many from CERNLAB or PAW). Those stuffs are pretty powerful in mathmatical calculation and simulations.
2. In some of my LabView code, I need to call his Fortran source code in order to do some complicated calculations. I have no capablility to translate his Fortran code to Labview (or is it even possible??), so we end up with trying to use "Call library function node" where I just provide input/outputs to communicate with his code. The idea sounds simple enough?
3. We complie the Fortran code into .dll, and then specifiy the dll in "Call library function node". The first try with a very simple Fortran code, something like c = a+b*a, was sucessful. The dll file and Call lib function worked good. It's sort of proved the concept.
4. Now I am trying more complicated Fortran code (say Test.dll), which calling other library (.lib files) that using typical "call xxx(a,b,c)" line, and my nightmare started.... It seems nothing was excuted when I call Test.dll in LabView.
Questions:
1. How do LabView know if the Test.dll code needs functions from other .lib files? Do I need to copy all the .lib files to a specific folder?
2. When I create .dll file, for LabView to be able to use it, are there any special requirement on the way the .dll is compiled?
3. Seems there is mismatch btw the data type in Fortran and LabView. For example, LabView's Signed 8-bit Integer seems different with a integer in Fortran. How can i know the correlation btw data type in different langurage, i.e. LabView vs Fortran?
4. Are there any good examples that I can take a look?
I would highly appreicate any suggestions/helps!
Rgds,
Harry

You are aware that Intel Visual Fortran is the successor to Compaq Visual Fortran (I think you made a mistype with the Virtual)? So an upgrade might be at its place.
Anyhow I'm really not familiar with Fortran at all, but lib files are usually compiled into an EXE or DLL and not loaded dynamically. 1)
So there should be no problem with locating those libs. What most likely is a problem are other DLL dependencies such as any Fortran Runtime library or possibly other third party DLLs the more advanced code in your DLL might be using.
Typically most compilers can be configured to link the runtime library code statically into the DLL, as altenbach reports for the Intel compiler, otherwise you must make sure to install the redistributable Fortran Runtime Library for your compiler. Besides that you must make sure to find out what other runtime dependencies your code might have and install them.
1) One exception I know of is LabWindows CVI which allows to also load lib files dynamically. This is supposedly a legacy feature from LabWindows for DOS, which allowed that feature to simulate dynamic module loading in order to swap modules at runtime to work around the 640k memory limitation of DOS.
