Error when calling a DLL function

Hi,
I am using external C++ code with labView. One of the DLL functions I use serves to call files. The directory and the name of the file is is passed as a parameter for this function. When the VI is running and arrives at this function (I use the Calling Library Function Node tool), the following message is displayed:
ERREUR de type class boost::filesystem::filesystem_error.
boost::filesystem:ath: invalid name "D:\Documents Johan\Johan\Stitching\Fichiers de mesure\front parfait\13z2" in path: "D:\Documents Johan\Johan\Stitching\Fichiers de mesure\front parfait\13z2"
I do not know why this message is sent to me.
Thanks for your answer
JF

Hello,
How are you passing the file path to the DLL -- are you passing it as a
string? If you are passing at as a string, I would do some basic
console output to make sure that your DLL is receiving the file path
corectly as a string and perform your appropriate C++ function in your
DLL. If the error is occuring with passing the file path you
might want to check out the links below for a little more information
on this.

It's been a while since I used extproc. Anyway, it listener.ora make sure extproc is added. I'll assume you are on Unix:
(SID_DESC =

(ENVS = "EXTPROC_DLLS=ANY,LD_LIBRARY_PATH=proper-directory-list")
(ORACLE_HOME = path-to-oracle-home)

Error when calling SOAP Runtime functions - Please help!

Hi,
Very new to SAP. I just installed SAPNW7.0ABAPTrialSP12 (sandbox server, with default options) and setup the

FRM-40734 when calling external DLL Function from Forms 6

Even though some answers were given to my previous help request ("Again: Forms 6 and user-defined data types") I wasn't able to solve the problem of passing a parameter of an user-defined type to an external DLL function residing in the SECURSIGN.DLL library (the closest solution was to declare that "composite" parameter using the ROWTYPE clause referencing a custom-made table created just for the sake of defining that perticular datatype).
So I concentrated on SECURSIGN.DLL functions using more trivial data types, like a function requiring just four character strings as parameters.
I generated the necessary PL/SQL support using the FFI.
I discovered that also the simplest calls to external functions fail at runtime with the generic error FRM-40734.
I located the error: it happens just at the moment of calling the function from within the FFI-generated package body. Before that, the DLL is loaded with no problem, the function is correctly registered, and a function handle is regularly returned.
As long as I can regularly issue the very same call with the very same parameters from Visual Basic, I can't understand what's going wrong (ALL the needed DLL are in the same directory as the FMB/FMX forms).
I will greatly appreciate any help that You may be able to provide.

I have noticed just now that a dump file having a name like ifrun60_dump_299, is generated by FORMS every time I issue the aborted call to the foreign function.
Inside the form dump file, apart from useless info like Registers and so on, the message:
"Could not find Module32First"
By a FILE/FIND/CONTAINING TEXT I searched all the DLLs, and I noticed that Module32First is a routine that can be found within each of the following DLLs:
Cl32
d2kwut32
d2kwut60
I tried to load those DLLs along with SECURSIGN.DLL by modifying the PROCEDURE LoadLibrary into the FFI-generated PLL code, and I have apparently no problem in loading all the DLLs that I wish, but the error persists, and that dump file is constantly generated, always looking for the "Module32First" routine.
How can I avoid all that mess and the FRM-40734 error??

Error when calling a Javascript function loaded as a library

Hi All,
I have some javascript functions in a custom js file which is in OA_HTML dir. I have loaded this js library using pageContext.putjavascriptlibrary("ABC","custom.js") in processRequest. When I deploy my code, there is a javascript error in the page. It does not seem to find the javascript function.
My code in PR is :
pageContext.putjavascriptlibrary("ABC","custom.js")
someBean.setOnFocus("javascript: callFunc(this);"); //callFunc(obj) is defined in custom.js
It works locally when I have my custom.js in myhtml directory. I am getting an error when I deploy the code on to the instance's apps server. Is there something that I am missing?
Thanks in advance
Raja

Raja,
You can bounce apache , and server cache would be refreshed!I guess then ur updated js function should work. Also,check ur js function works correctly on jdev.

Anyone ever see this error when calling a dll? "Arbitrary.dll?"

Hey folks, I'm attaching a jpg of the error I get as soon as I try and load a vi whose subVIs call a "Call Library Function".
Double clicking on the call function I can verify that the 'Library name or path" is correct, and the Function name is what I want.
I do not understand why it is telling me I need "Arbitrary.dll" - the name of the lib is adwgc.dll as indicated in the path (that I verified).
Anyone deal with this error before? I'm pretty clueless at the moment, any help will be appreciatized and surely kudo'd!
thanks
-pat
edit- also, I'm using LV 2011
Solved!
Go to Solution.

You get this error because adwgc.dll is internally loading Arbitrary.dll because whoever wrote adwgc.dll called some function in Arbitrary.dll. The only to fix this is to get Arbitrary.dll and put it in a folder that adwgc.dll can load it from. Putting it in the same folder as adwgc.dll should work.
Where did you get adwgc.dll from and are you sure they didn't supply Arbitrary.dll as well?

LV 6.0.2: an App-built dll gives a runtime error when called by C

I want to use Labview 6.0.2 VIs as DLL's in a Borland C++ Project.
Starting with the simple I have made a VI that returns a constant int32 then built a dll with the Application Builder and put the dll and include file in a BC++ project directory. Compile and link seems to run well. But when excuting the call to the LV fuction gives Fatal Error: labview.lib was not called from a Labview process.
It seems this question was posted before, but answer didn't help me, Sorry.

Hi Gabriela -
This question is answered in the KB article entitled : "LabVIEW.LIB Error When Calling a DLL Built with LabVIEW"
The link for this document is -> http://ae.natinst.com/operations/ae/public.nsf/fca7838c4500dc10862567a100753500/a4c3aef93240280a86256931006fb66c?OpenDocument
Or you can go directly to www.ni.com/support and search for this document and others to help.
The reason for this is that the old labview.lib does not know how to correctly locate the LabVIEW Run-Time Engine when called.
From the document I posted ->
Your dll is most likely making a call If you want to call a Windows DLL or CIN built with a version of cintools before LabVIEW 6.0, you must relink the DLL with the labview.lib from 6.0. If you call an old DLL or CIN in your LabVIE
W DLL, you receive the aforementioned error and the application terminates, because the old labview.lib does not know how to correctly locate the LabVIEW Run-Time Engine when called in this situation.
Good luck-

Javascript Error when calling EPCM.raiseEvent

Hi all!
   I'm having a Javascript error when calling EPCM.raiseEvent function. The error is :
   'The object does not accept the method or property'
Maybe the traslation is not perfect (I'm using spanish for my browser). Here is my call:
   EPCM.raiseEvent('myPar','myEvent','myParam');
What can be wrong?
Thanks in advance, and sorry for my terrible english.

Hi!
   This error is very strange... I accidentally changed the event name at consumer, but not at producer.... and the error didn't appear... Obviuslly it did'nt work, but it's so strange that if the event is not cought, there is no error (but nothing happens)
   I also noticed that doesn't matter which event I raise (I have two of them), the error is thrown at the same line, and they have totally different caller and receiver functions....
Thanks In advance.

FRM-40734 when calling a foreign function requiring more than 1 dll

I have been experiencing difficulties in calling external DLL functions from SECURSIGN.DLL. This time no peculiar type of parameter is involved, just four varchar2.
A dump file "ifrun60_dump_nnn" is generated by FORMS every time I issue the aborted call to the foreign function.
Inside the form dump file, apart from useless info like Registers and so on, the message: "Could not find Module32First"
I know for sure that SECURSIGN.DLL needs also other DLLs, and that the first foreign function I call, calls other functions in other DLLs. I found that Module32First is a routine within each of the following DLLs:
Cl32
d2kwut32
d2kwut60
I copied all those DLLs in the current work directory along with my FMB/FMX, in ORANT\BIN, in C:\WINNT\SYSTEM.
I modified the PROCEDURE LoadLibrary (part of the FFI-generated PLL code) to load those DLLs along with SECURSIGN.DLL: no problem in loading all the DLLs that I wish, but the error persists.
How can I avoid all that mess and the FRM-40734 error?? Is there a specific problem in resolving the references to other DLLs?
Please notice that - on the same computer - in Visual Basic everything (and the very same call in particular) works perfectly.

Calling CVI DLL Function from Visual Studio

HI all ,
Iv'e created a DLL using CVI and i'm tring to call one of it's function from visual studio 6.0
I'm getting a general error , is there a specific prototype that i need to set my functions in ordrer to call them ?!
Kobi Kalif
Software Engineer

You will need to distribute the CVI RTE along with your DLL, since anything you write in CVI is going to use the RTE.
As far as calling the DLL functions, you can use the CVI defined macros
<return type> DLLEXPORT DLLSTDCALL <function name> (<param1 type> <param1> ...) {
to declare your functions in the DLL for access by a VS application.
for example
int DLLEXPORT DLLSTDCALL myfunction (int funparam1, double func param2) {
There are options for identifying which functions to export from your DLL, I use "functions marked for export" but there are other choices available. I also include a type library so when you type the name of a DLL funciton in VS6 you see a balloon popup with the function signature. This is a check box in the target settings. You have to create a ".fp" file (function panel file) to collect the function info for the library.
From VB6 you can access the DLL a couple of ways, but I usually add the DLL as a reference.

Formal error: Invalid calling sequence for function modules

Hi All,
I have developed a function module for FQEVENT 620 Payment: Transfer Line Items for Clearing.
The clearing works fine.
After clearing the open items i need to post an FI-CA Document(BAPI : BAPI_CTRACDOCUMENT_CREATE) for each open item(cleared item)
I have used the bapi : BAPI_CTRACDOCUMENT_CREATE in the same function module that i have developed for FQEVENT 620 Payment: Transfer Line Items for Clearing.Here i am getting an error "Formal error: Invalid calling sequence for function modules".
So please let me know where i can use this bapi to post fi-ca document.Is there a BAdi or Enhancement Spot where i can use this BAPI or tell me what should i do to overcome this error.
Regards
Venkat

Venkat:
While I am confused about your business process - creating an open item when clearing one seems strange. Look into event 0020 which is called after documents are posted - it may present the opportunity to post process additional documents.
regards,
bill.
