Can a VI compiled in dll be called in LV?

Hello,
I have some dll´s, which use some common VIs. This means, each time when I compile a dll, the VI will be compiled within the dll. What habbens, if I compile the same VI in another dll, and call the dlls in the same time. Will be there a collision, that the VI is already loaded , by calling the second dll?
regards
Mitulatbati

Maybe I did not understand the question correctly...
If you have a vi that is compiled into a dll and then from another vi (main) you call both the original VI and the dll, it should not collide as you would be calling different objects.
Have you tried it and having problems?

Can't step into CVI step that calls LabVIEW DLL?

Windows 2000 SP1
TestStand 2.01f
LabWindows CVI 6.0
LabVIEW 6.1 Runtime
We have a framework based on TestStand and CVI. A customer has supplied us
with a DLL written in LabVIEW 6.1 and packaged with the Application Builder
that we need to call from a CVI test library DLL. They say they can't
supply us with a non-LabVIEW implementation. We installed the LabVIEW 6.1
run-time. We added code to the CVI test library to dynamically load and
unload the LabVIEW DLL using LoadLibrary and FreeLibrary. LoadLibrary is
called in a function in the MainSequence Startup step group, FreeLibrary is
called in a function in the MainSequence Cleanup step group.
Things run as expected when the CVI DLL is built as Release or Debug and the
CVI
adapter is configured to run in-process.
However, if we try to debug CVI DLL by building it as Debug and configuring
the CVI adapter to run in an external instance of CVI, things hang the first
time we try to step into, or run, a CVI test library step that calls one of
the functions in the LabVIEW DLL. On the Applications tab in Task Manager,
the item named LabVIEW is marked as 'Not Responding'. The only way to
recover is to kill the LabVIEW process, which takes down CVI and TestStand
with it. If none of the LabVIEW DLL functions are called, no problems are
seen (no hang).
I assume the problem has something to do with the library getting mapped to
the wrong process space (TestStand v. the external CVI instance). Is there
any way to solve this problem? Any ideas or suggestions would be
appreciated.

When 'debugging' SeqEdit from CVI, we experienced no lock up.
Thanks for this suggestion. Debugging from CVI is a workaround for now,
though not highly desirable as it is reverse from normal debug proc
edure
(user can't step into CVI from TestStand). Still would like to know if
'normal' debugging of this problem is possible.

The problem appears to be general to LabVIEW DLLs called from an external
instance of CVI under TestStand. We were able to reproduce the problem with
a simple LabVIEW VI compiled to a DLL, then called from a simple CVI DLL
under TestStand. We will package up some sample code and submit it to NI
tonight or tomorrow.
Thanks for you help.

Is it possible to step into a CVI dll when called by TestStand?

As the question says: "Is it possible to step into a CVI dll when called by TestStand?"
I am sure Ray F. may have a few tricks up his sleeves... Hope you see this post, Ray!
I compiled a dll using CVI. The dll is called as a test by TestStand.
I do have an "exe" version of the code that I use for debug with a testbed, but the behaviour is not the same as testing the actual target while running TestStand. My goal is to get as close as possible to the real events.
Thanks,
JLV

Sorry about that,
There are two ways as I was saying:
1. You can configure the CVI adapter to Execute Steps in a External Instance of CVI (requires CVI 6.0 or greater).
Only go to Configure->Adapters and select the LabWindows CVI adapter and click on configure and select the corresponding option.
After that set a break point in the step that you want to debug.
An external instance of CVI will be launched where you can set break points and step into the code.
2. From CVI Specifying an external process:
In CVI go to Run Specify External Process and enter the seqEdit.exe as the program name (you have to browse to the location <TestStand>\Bin\SeqEdit.exe).
As the argument you enter the name of the sequence file you want to debug.
Now just select Run->Debug SeqEdit.Exe
The Sequence Edtior will be launched and you can set break point in your CVI code and step into it when the step is executed.
Check the Using LabWindows/CVI with TestStand reference manual for more information.
I hope it helps you to get started.
Regards.

How to compile a dll in window

Hi ALL:
I want a compile a java program through natvie method in c . Below is my code
cl -I"c:\Program Files\j2sdk_nb\j2sdk1.4.2\include" -I"c:\Program Files\j2sdk_nb\j2sdk1.4.2\include\win32" -I"c:\Program Files\Microsoft Visual Studio\VC98\include" -LD Analyze.c -FeAnalyze.dllAnd there is a error message
Command line error D2003 : missing source filenameBut I certain a file called Analyze.c in the path , why ther error ouccer???
Can anyone help me
Thanks in advance

Hallo,
You have not specified your problem very well. As I understand it, you want to be able to start the Java VM from C, and then call some Java methods from your C code. Is that correct? Or are you trying to create some native methods, that you can call from java?
Your first problem is that you have not specified any code! You have just shown how you want to start the Microsoft compiler to compile your DLL. You have clearly not specified the compiler parameters correctly.
I respectfully suggest that this is the wrong forum to get help with your Microsoft compiler problem. You need to read the documentation that comes with the compiler. It is very comprehensive. I would in any case ask: Why are you trying to compile your code from the command line? It is normally very much easier to create a Visual Studio project and do everything from within Visual Studio itself.

Thrid party DLL function call.

Hello,
I am a programming novice trying to learn more about Java. I am currently working on a project for my employer (a side project really) that is used in generating some specific alpha-numeric codes. Actually, I am re-writing an existing program into Java as a personal exercise for myself but it may have some useful applications down the line.
This project requires me to use a 3rd party DLL function call. I have been trying to follow through the process of using the JNI interface, however, I believe that I need to create a wrapper DLL to handle the function call. Does anyone know how to do this or can they point me in the right direction? I believe the 3rd party DLL was written in C++ but that's all I know at this point.
Any help is appreciated.
TIA

To those of you who will look this topic up and wonder how I was able to do that here:
(using Visual C++ for the example)
3rd party DLL : Key32.dll
wrapper DLL: Key32Liaise.dll
SWIG interface: Key32Liaise.i
wrapper class: Key32Liaise
1) Make reference to your external function call as if it were a class method. The class name should be that of your "wrapper" class. (e.g. Key32Liaise.getHashCode() ) I like to call the wrapper class the "laise" class because it acts as the go-between.
2) Download SWIG. Create your interface file and run the command: swig -java -shadow -c++ Key32Liaise.i This will generate Key32Liaise.java shadow class and Key32Liaise_wrap.cxx wrapper code.
3) Compile the Java code into Class files and generate a header file for the wrapper class (i.e. javah Key32Liaise). You will need this header file even though the SWIG site doesn't mention this.
4) Open VC++ and open a new project file Key32Liaise to create a DLL. Write the C++ code that calls up the function from the Key32.dll file. You will have to look that up from the MSDN site...too much to put down here.
5) Include the appropriate files and complile the wrapper DLL.
Hope that make sense!!!

Compiling a .dll in netbeans (Almost there)

(I have the GNU g++ cygwin compile installed and selected to be used as C compiler in netbeans)
I have got so far but falling at the last hurdle.
I have modified a java wrapper so that I can put it in a package, I adjusted the code, compiled it, called javah on the source class using:
javah packagename.classname
which worked
I've then re-written the wrapper.c file so that it includes this new header file classname.h
I've re-written the methods so that they start with Java_packagename1_classname1_ (the way they appear in the header)
I've created a new C/C++ project in netbeans (Selected dynamic linked library in options)
I've added the exsisting classname.h files + Cdll.h file to the header files (both included in the wrapper.c)
Now I should be set to compile my wrapper.c into a .dll file
I press the build button and I get this:

Crash "DAbort 0x37C03D in MemoryManager.cpp" when calling DLL with "Call Library Function Node"

Hi all,
I would like to work with a LabVIEW program that I did not programm by myself.
In this programm an external DLL needs to be called. in the Momente this dll ist called with the "Call Library Dunction Node" LabVIEW crashes with this Error Message:
DAbort 0x37C03D in MemoryManager.cpp
Attached is the entire Log.
The programm runs on the computer of the original programer.
I have never handeled with DLLs or something like that before, so I have absolutely no idea how to rsolve this problem.
Thanks for your help!

A DLL can be compiled by different compilers. By "generic" C DLL, i refer to ANSI C (so no C++, no Borland C or something else).
My question is raised as parameters, esp. arrays and strings, can lead to this behavior when used in the wrong way (including "Calling Convention").
Also, interfacing with the LV memory manager can lead to crashes like this, but this wouldn't be a "generic" DLL as it binds to LV (due to LV API calls).
Without a better knowledge on the DLL and its functions, there is not much we can help you with.
Where does the DLL come from?

HT201210 After downloading latest version of iTunes it will not open. This error message is displayed; The program can't star because MSVCR80.dll is missing from your computer. Try reinstalling the program to fix this problem. Then a second error box

After iTunes requested that I download latest version on PC it now will not open. 2 error messages appear. first: The program can't start because MSVCR80.dll is missing from your computer. Try reinstalling the program to fix this problem. second: iTunes was not installed correctly please reinstall iTunes. Error 7 (Windows error 126). I have tried reinstalling a number of times and restarting computer but no luck.

This happened to me today as well post installing the latest version of itunes. I did a search on google for the error and came across a recommendation to :
Note: Start Windows in Safe Mode to complete any of the following steps if you're unable to access Windows normally due to the msvcr80.dll error.
If, and only if, you're receiving the msvcr80.dll is missing error when you open Apple iTunes, do the following: (skip this step if your msvcr80.dll error is occurring with a different program)
Uninstall from Windows the following five programs in this order: iTunes, Apple Software Update, Apple Mobile Device Support, Bonjour, and finally Apple Application Support. If you have iCloud, remove it as well.
Uninstalling these programs in Windows is done from an applet in Control Panel called Programs & Features (in Windows 8, 7, or Vista) or Add or Remove Programs (in Windows XP).
Note: Songs and playlists in iTunes will not be removed when you uninstall the iTunes program or any of the other, already-mentioned Apple programs. If you'd still like to back them up, they're usually located in the My Music folder in Windows.
Download the latest version of iTunes from Appleand note the location you're saving it to so you can find it once it's done.
Run the iTunes installation as an administrator. If you're not sure how to do that, see How Do I Open an Elevated Command Prompt? for help. That procedure shows you how to open the Command Prompt program as an administrator, but the steps are essentially the same for anything, including the iTunes installation package you just downloaded.
A general overview of removing and reinstalling iTunes can also be found here on Apple's site but the above procedure seems to work better in this particular situation.

Call a special function in the dll using Call Library Function Node????

Dear all,
I am calling a special function in the dll using call library function node. There is a input parameter that it is a enum type in this function. I don't know how to deal this parameter for calling this function.Has anybody solved this problem?Please advise!
I am appreciated of you anytime.

Most of the times an enum is just a U8/U16/U32, internally so probably you can call it with just a U8/U16/U32 or something. For the correct value you have to look at the definition.

Call multiple functions from same dll with call library function

hi,
i am working on a project in wich we need to make a UI to read out a sensor network.
the UI should be usable in any project, but every node needs a different piece of code depending on the type of sensor with wich it is equipt.
so i need to be able to call different pieces of code when i need them, and still be able to use the UI in future projects with possibly new types of node we now don't have.
so someone told me to use DLL's, cause then i would be able to call the code i need the moment i need it.
but i have never worked with DLL's (just learned about this option 3 day's ago) so i have a question.
i know i can dynamicly change the DLL i call with the call library function, but can i dynamicly change the function i call from that DLL ?
or do i have to put a new call library function for each function i want to call, even if its from the same DLL ?
kind regards,
stijn

ok so there is no (easy and ubderstandable) way for me to dynamicly change wich function i want to call from a certain DLL.
but now i started wondering, the path on the call library function is not ment to dynamicly change a DLL

Thepath on the Call Library Node can be used to load a different DLL. Obviously since you can't change the function name your other DLL would have to export exactly the same function name and of course with the same parameters. This is seldom the case so it is not the main use of the path input to the Call Library Node. It's main use is as indicated to load DLLs at runtime rather than at load time of a VI. So that an application can run even when the DLL is missing, until the moment the functionality from that DLL is needed.
If you can make sure that all your DLLs export the same function name with the same parameter you can use the Call Library Node to call into different DLLs through the path input. If however you would need to call different function names you would have to resolve to some DLL which does do the dispatching and invocation using LoadLibrary() and GetProcAddress(). But unless you need to go with DLLs for some reason using the Call By Reference Node can give you an even more flexible approach.

How to compile a dll for JNI in the CMD correctly

Now I find alot of old threads on using the mno command in cygwin to created dlls to use as an interface between c and Java, however I know this command is no longer available in cygwin and so I took the advid of downloading minGW and using this in the CMD instead.
However every example I try to compile and run this way throws the unsatified link error when the native function is to be called by the Java program. I believe it must be a compiling error creating a mismatch between the native function and the function to be called.
Here is the method I'm using to comile dlls for JNI, it is from the FAQ section of the minGw website:
gcc -Wall -D_JNI_IMPLEMENTATION_ -Wl,--kill-at
-Ic:/j2sdk1.4.1_02/include -Ic:/j2sdk1.4.1_02/include/win32
-shared someJavaImp.c -o JavaImp.dll
Is this how dll should be compiled? If not any suggestions?

ACCESS_VIOLATION at AdobeOwl.dll when call Indesign com interface from windows service

ACCESS_VIOLATION at AdobeOwl.dll when call Indesign CS3 COM interface from windows service application.
Does anyone know how to workaround this issue ?

As AdobeOwl.dll file is missing or corrupted, you need to get a new dll file. Here are the steps to replace setup.dll file
Step 1. You can download missing AdobeOwl.dll here:
http://dllcentral.com/AdobeOwl.dll/1.0.92/download/
Step 2. Paste this file into your system32 or SyWOW64 folder.
Step 3. Navigate to your System32(32Bit OS) or SyWOW64(64Bit OS) Folder.
Note: The location of System32 and SyWOW64 is
C:Windows\System32 (If you are using 32Bit Windows)
C:\Windows\SysWOW64 (if you are using 64Bit Windows)
Step 4. Paste the AdobeOwl.dll file into this folder.
Step 5. Try to run it. It might work now. If not, restart your computer to restore it effectively.

I am not ale to compile my DLL when I am linking to laview.lib

shipped with LV5.1 but labview.lib shipped with LV6i is fine. I am using DSSetHandleSize and DSNewHandle in my DLL. Any ideas? I am using VC++6.0. The errors I get is: MSVCRT.lib(MSVCRT.dll) : error LNK2005: _exit already defined in LIBCMT.lib(crt0dat.obj)I am not ale to compile my DLL when I am linking to laview.lib shipped with LV5.1 but labview.lib shipped with LV6i is fine.

There may be other two libraries in your computer. One is nivxi.lib in C:\Program Files\National Instruments\MeasurementStudio\vxi\extlib\
And another one is nivxint.lib in C:\Program Files\National Instruments\VXI\nivxi\api\win32\msvc6\
You can do a search for these two libraries in your computer, and use them without cvi.lib. If you use the second one, nivxint.lib, you should ignore MSVCRT.lib by editing Project>>settings>>link>>Input>>Ignore Libraries.

We can not clear all recents(30 recents call). When Tango show "No recents call". We touch other buttons and come back to Recents button again. It still show 30 recents call.

No one here is going to do anything about it. Send feedback to Apple.
