Using DLL's to call tuxedo routines

I have a service application which requires the use of a DLL in order to execute

You can communicate with two ethernet cards. However, I don't know about them being on the same subnet. There are a few Dev Exhange postings which refer to this type of application:
Can I use 2 ethernet cards in 1 PC with LabView?
How c
an I use 2 network cards in LabVIEW?
You might want to take a look at those to get some tips. I've never actually done this before, but it sounds like you need them to be on different subnets.

Do i have to use .h files to call .dll files?

Dear,
Now i want to use labview to control an instrument. And the instrument company give their dll files.
When i use tools---> import---->share library,labview tells me import .h file,but their are many .h files,you know you can just choose only one head files in labview at the same time.So should i write a new .h file to concluding this head files and every thing will be ok?it is complicated.
I use another method to call .dll and it is CIF.But i also encounter new problem.When i invoke the node .dll,and then choose the functions,i find that the functions are void.Does It meanthat i can not input my parameter,and get output?
So what' the problems?
Thanks.

To call a dll in LV, you have to use the Call Library Fuction node in your BD. Then dbl-click it to open the Configuration dialog. In that, you have to browse to the appropriate folder in teh Function tab & select the dll you want to call. Then select the function from the list populated down to it. Then go to the Parameters tab & select/assign the parameters for that function. This will do the job.

You can't do that with JOLT. You will need to use the WTC product,

How to call tuxedo in Visial basic?

The version we are using is Tuxedo 6.5.
Now we want to call tuxedo in our VB application. but tuxedo is a field we have
little touch with.
So i have no idea how to bind these two together.
Hope you kindly give a hand (maybe some documents on this)
thanks a lot in advance. Look forward to the prompt reply!

1.In the VB IDE i have installed the SP5.
2.The version of the tuxedo is 6.5; %TUXDIR%\udataobj\patchlev is not found in
my system.
What is the file?
3. again,Would tpinit() works well without relevant server booted?
thanks for your prompt reply.

I don't know; I haven't worked with that stuff. Since you said the error
is:
"vb6.exe have error occured -- will be closed by windows -- you will
need to restart
the program"
I would check to see that the VB or VS service packs have been installed.
Visual Studio had SP5 last time I looked.
Then, which version of Tuxedo do you have and is there a file called
%TUXDIR%\udataobj\patchlev ? If yes, what is the very LAST line in it?

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".

Extproc crashes when calling external routine

Can anyone point me to documentation on the causes of extproc.exe crashing when trying to invoke an external procedure? The standard documentation set isn't too helpful for debugging such a problem.
I have been able to call one external procedure. With two others, I always get an extproc crash with (I believe) an access violation.
The routines I am trying to call are 3rd-party, so I do not have the ability to view their source, though I do have the list of parameters and the sizes and types.
What I am hoping to find somewhere is a list of the kinds of things that cause extproc to crash so I can see if any of them are likely culprits in my situation.
Thanks,
Bruce Merkle

Have you tried calling into the dll that CVI calls directly from TestStand? I am curious to know if this also crashes.
I am also curious to know if there are any path references in the dll that is called by the CVI program. If so are they relative, or absolute paths?
I ask because one of the possibilities is that relative paths are being used to specify a path from the location of the code that is called, and they are not working because the current working directory is being specified by TestStand, and the paths are not relative to the working directory given by TestStand.

Error 420 "Can't call builtin routines remotely" while compiling a proc

I get the message above when I try to compile a Forms procedure with a call to specific functions in the DBMS_UTILITY package. I am using Forms 10.1.2.2.0 and 10g DB (10.2.0.4.0). I want to trace the PL/SQL path that my Forms application is taking and be able to report the line number of the failure when an exception is thrown. I am able to call some routines within the DBMS_UTILITY package, but not any of them that have "pragma interface (C, format_error_stack);" in the code. These include format_call_stack, format_error_stack, and format_error_backtrace; all of which I would like to use. I've tried creating my own DB package function to act as a wrapper; this allows me to compile the form, but the call to the function form my exception handler returns null. These are really useful functions, but I do need to be able to access the functionality from within Forms. Does anyone have a solution/workaround for this problem. Note, this is similar to the question in Link:[ http://forums.oracle.com/forums/thread.jspa?messageID=504922��]
Thanks JK.

Nope, that does not work. See my first post above. I've tried using a wrapper, and whilst this allows my forms procedure to compile and my form to run, the wrapper procedure is returning null. Here's some code that may help to explain where I'm at. In the form, I've got -
DECLARE
    l_bt VARCHAR2(2000); -- BackTrace
BEGIN
    JEK_Raise_Exception; -- This is a DB procedure
EXCEPTION
   WHEN OTHERS THEN
      l_bt := KEYOWNER.Backtrace.generate_backtrace;
      message('l_bt = '||l_bt); pause;
END;-- Then a DB procedure that just generates an exception
CREATE OR REPLACE PROCEDURE JEK_Raise_Exception IS
BEGIN
   RAISE too_many_rows;
END;-- and the function from my Backtrace Package to return the backtrace data.
   FUNCTION generate_backtrace
       RETURN VARCHAR2
   IS
      l_bt      VARCHAR2(2000);
   BEGIN
       l_bt := DBMS_UTILITY.format_error_backtrace;
       RETURN l_bt; -- In my testing so far this has been NULL!!!

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.

Call a routine in a dynamic action.

Hi Experts,
i want to write a routine in which i can give the error msg while saving the infotype 0002 incase the given condition is not fulfilled.
Can you tell me where i can write this routine and how to call it in a dynamic action.
i hav written other types of dynamic actions before but never called any routine before
Plz give me the detailed info regarding writing a routine.
regards
TS

Hello TS,
You can do that using F in Indicator for step but iam not sure whether it will return an error message. We have user exits for this which might solve your issue. We have userexit PBAS0001 and in this EXIT_SAPFP50M_002 Function module, we need to write the code which ever you want to do.
For Calling FORM in Dynamic actions.
P - Check conditions
I - Maintain infotype record
W - Set default values when creating a new record
V - Reference to another step
F - Call routine
M - Send mail
Say you have a program ZTEST. In this you need to write the form that needs to be called in dynamic action and say for ex:form_test.
You can fill only structure RP50D values, because these values you can get it back to dynamic action. ypu can check for examples in dynamic actions it self which have 'F' indicator step.

Can i use malloc function while using DLL created from C program

Hi,
I have written a simple program in C , which uses malloc function for allocating memory for the array.When iam calling that DLL using call library function node in labview, it is not giving any output, my doubt is can we use malloc function in C program from which we will create DLL and is called in labview? I am attaching my C code and DLL and also labview file please tell me where i am doing wrong?
Thanks & Regards,
Vishnu

Hi Vishnu,
There's no problem using the Malloc function in C and call it as a DLL in LabVIEW.
But LabVIEW has a different memory management than C.
It is probably not recommended to allocate array memory in C for labVIEW arrays
You can use initialize array in LabVIEW instead.
Good luck

Is it possible to call Java routines from FMS?

Say I have a game package, most of which
are written in Java. I am thinking
to leave the core logics in Java, but
change the user interface into Flash,
and serve it over FMS. Now is it
possible to call Java routines from
FMS?
I'd appreciate any suggestions.

Yes! You can use SOAP(or XML-RPC) to call Java routines.

Btw, does anyone know if there is XML-RPC package for

Next I check Shadow Copies details from volume properties (right click on C or other drive then select properties then click on Shadow Copies Tab) and found it is showing the same error code..
From this error it is clear that the issue is inside the registry hive and due to junk hive shadow copies services not able to working properly.
For me the server have two disk we check disk signature at MBR and found the disk signature was.
Signature disk 0 : 9351912b
Signature disk 0 : FDFBE035
But at registry we found lot of nonexistance signature. Which indicate lot of junk valu inside registry.
Now how can we resolve this issue?
It is very simple just delete the registry key “volume” (registry key “HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\STORAGE\Volume”) and reboot the server it will “Volume” registry hive automatically.
Note:
When you remove registry key it is showing error unable to delete, then please right click on it select permission then take ownership and assign full permission to your login account.
Please be careful when you delete registry key because system can fully crashed if you delete or modify wrong registry key.
Your can take a backup of the registry key by exporting.

OSB calling Tuxedo Not transactional?

I have a web service with methods in it that calls OSB services (which I have configured to call Tuxedo services exposed through the WTC). However, my calls don't seem to be transactional... is there a way to conifgure OSB to be transactional when calling Tuxedo services exposed through WTC?

Let me describe how I am calling these Tuxedo services...
1. Import/expose Tuxedo service via WTC...
2. Create an OSB business service bound to one of the imported services
3. Create an OSB proxy service that creates a route that calls the business service created in #2, pretty simple, no transformations done
4. Create a web service front end that calls the proxy created in #3
So, everything seems to work using #1-4, except of course the non-transactional issue. So, to fix this what I attempted to do was to replace the value of the outbound qualityOfService variable from "best-effort" to "exactly-once". To do this I modified #3 to add a replace message processing action to modify the quality of service attribute to "exactly-once". I got this working (looks like it's modifying the request going into the business service), but still no luck having the Tuxedo side of things to be transactional. Maybe I'm still not doing something properly...?
Here is the request getting passed into my business service from the proxy:
Route to: "InsertBusNotesBS"
