Associer une dll à un projet et executer un programme appelant sans mettre la dll dans VXI pnp

Bonjour
Je souhaiterai exécuter un programme appelant une dll que j'ai compilé et que j'ai lier à l'exécutable mais pas placé dans VXI pnp.
La compilation se passe bien mais lorsque je lance l'application, un message apparaît et indique que la dll est intraouvable j'ai inclut le chemin du dossier dans lequel est stocké la DLL dans les include path mais sans succès.
Merci d'avance pour votre aide

Bonjour,
Merci d'avoir posté votre question sur le forum de National Instruments.
Pourvez-vous m'envoyer votre code?

K-MELEON executed an invalid instruction in module NPSWF32.DLL at 0177:03715767.

There is a bug in the Flash Player 9.0.115.0 that crashes
K-Meleon at kidswb.com after I press enter. First there is and add
for EON KID and it switches to the BATMAN add I recieive the error
message "K-MELEON executed an invalid instruction in module

The thing is, these errors occur at seemingly random times and sometimes not at all. I have removed all but the latest jvm.dll but to no avail. I suspect that some kind of run-time exception is the real culprit, but one seemingly impossible to pin down (possibly due to timing or memory usage). It would help greatly to know what the error messages are refering to - the hex that is.

Resource-only DLL does not contain executable code

A resource-only DLL does not contain executable code. Since
LoadLibrary (http://msdn.microsoft.com/en-us/library/windows/desktop/ms684175.aspx) attempts to call the entry point before returning, it will fail for resource-only DLLs. Instead, you should call
LoadLibraryEx (http://msdn.microsoft.com/en-us/library/windows/desktop/ms684179.aspx) passing a
LOAD_LIBRARY_AS_DATAFILE, LOAD_LIBRARY_AS_DATAFILE_EXCLUSIVE, or
LOAD_LIBRARY_AS_IMAGE_RESOURCE flag, to load a resource-only DLL. This prevents to loader from attempting to call the entry point.

Hello,
Just check if there is space in the front of these numeric values or some garbage value...if there is... then it may not be able to pad it up with zero and hence the issue...check in R/3 about how these values are stored...you can remove the space from the front and change it in PSA...and then load but first do the analysis of the source system and see why its coming up wrong.

Want help to execute the programm of MethodEntryEvent

Hi,
I am trying to develop a programm for automatic logging in the programme. I took the hepl of java API and the Google site for searching some programms and successed also. but while running these sample programms i am getting classNotFound exception and some other exceptions also. i executed the programm Seq.java downloaded from the site http://search.cpan.org/src/PHILCROW/UML-Sequence-0.05/java/Seq.java. i am not able to understand how to execute it. what ever i tried its giving the same output whatever defined in the System.err() in the file. but it should display the corrosponding class details for which i need to see the output.
can anyone help me in this regard and tell me the process to execute the programm.
i took another e.g. trace example, which (in J2SE 1.4.x or 5.x) will be found in $JAVA_HOME/demo/jpda/examples.jar and unpacking it by
jar -xvf $JAVA_HOME/demo/jpda/examples.jar i found the
com/sun/tools/example/trace/Trace.java
when i tried to execute it to see the output for some other programm i got the following exceptions,
-- VM Started --

-- The application exited --
i execute this programm i used the command as
java Trace -output trace.log DateExample
where trace.log is output file and DateExample is the java file.
Can any one help me in this regard to execute the programms and can give me a detailed solution procedure.
can anyone suggest me any other programm for auto exit and entry display for classes or methods with detailed execution steps.
Thanks,

Hi,
i tried by setting the class path in the environment variables.
still i am getting the same exceptions. i m sending the files on which i m working and requesting to give some solution. the files are

Execute another programm from Java

Hello Java Gurus,
I am developing a java app that reads from my DB and do some calcs with it. I would need to execute another programm later sending some of the data as parameters.
In C I would use _exec() function, is there any function like that in Java?
Many thnks,
AC.

There is a method like
runtime.exec();
you could use that.

The procedure entry point NS_Set DLL Directory could not be located in dynamic link library Xul.dll. Firefox 4 downloaded and used yesterday won't start today. Any answers?

I downloaded Firefox 4 yesterday. I used it and had no problems. I started my computer today and clicked the Firefox icon and got the message "The procedure entry point NS_Set DLL Directory could not be located in dynamic link library Xul.dll" .I tried to shutdown and restart and got the same message.I use Norton Security. Could it not recognize Firefox 4 and done this?

'''Edit: '''That was a lot of questions. You might want to just re-run the Firefox 5.0.1 installer to see whether that corrects what appears to be a mismatch of files. I suggest saving the installer to the desktop, restarting Windows to ensure that all file locks are released, and then running the installer. As always, you can download from here: http://www.mozilla.com/firefox/all.html
In your other post, you wrote "I just downloaded FireFox 5.0 today, and none of the icons on my desktop will open. This is the message that I receive. The procedure entry point NS_Set DLL Directory could not be located in dynamic link library Xul.dll."
Can you describe what happens in these different scenarios:
(1) Start Firefox with its own program icon. Error dialog, but Firefox runs normally after you dismiss it? Or no error? Or Firefox won't start?
(2) Firefox not running, double-click shortcut to web site on desktop. Error dialog but Firefox loads the page after you dismiss it? Or Firefox doesn't load the page? Or Firefox never loads??
(3) Firefox running, double-click shortcut to web site on desktop. Error dialog but Firefox loads the page after you dismiss it? Or Firefox doesn't load the page? Or Firefox dies??
(4) Double-click unrelated desktop shortcut. Does this give an error as well?
If you've noticed effects with links in documents or emails outside of Firefox, that could be a clue as well.

update your graphics card drivers.
if that fails, reset your preferences.

TS1470 Error message - DLL file - Unable to execute a necessary DLL file

Hi there,
I tried to Install Itunes (iTunes 11.0.2 for Windows (64-bit)), but I get this error message, see attached image:
It is in Dutch, but it says:
"There is a problem with this Windows Installer-package.
A DLL-file which is necessary to complete the installation, can't be executed,
Please contact your system support or the application supplier."
Can anybody help me out please?!
Thx,
mvanrenssen

Agree with RajaRani. For instructions on the procedure (doing a "run as administrator" on the installer file), see the following user tip:
"The administrator has set policies to prevent this installation" error messages when installing iTunes for Windows on Windows Vista and Windows 7 systems

Comment lancer un projet sans toucher aux dll ou librairie déjà existentes

Bonjour,
je dois faire un programme sur labwindows qui sera utiliser sur plusieurs PC, pour piloter une carte d'acquisition différentes à chaque fois (des vieilles PCI comme les PCI-6014 ou plus récentes comme les PCI-6221). Par contre les drivers, les versions de DAQmx sont aussi différentes selon les PC. Je voudrais donc (si c'est possible), renommer les DLL ou librairies indispensables afin de lancer l'exécutable, sans pour autant désinstaller ou remplacer les DLL ou drivers déjà existants.
Comment dois je m'y prendre ?

Bonjour mhen29,
Merci d'avoir posté votre question sur le forum de National Instruments.
Je vous conseille d’utiliser le logiciel NI-DAQmx 9.5.1 que vous pouvez trouver sur notre site. Vous pouvez le télécharger sur le lien suivant : http://joule.ni.com/nidu/cds/view/p/id/319/lang/fr
Ce logiciel regroupe différents drivers dont ceux que vous spécifiez pour vos cartes PCI-6014 et PCI-6221. Les différents appareils supportés se trouvent sur le lien suivant : http://download.ni.com/support/softlib//multifunction_daq/nidaqmx/9.5.1/readme_fra.html

Générer une tension puis la mettre en DLL.

Bonjour,
J'aimerais réaliser un programme permettant de faire varier une tension1 en fonction d'un temps1, puis une tension2 en fonction d'un temps2. Ces 2 tensions doivent etre généré sur la même voie de sortie chacune leur tour. Après avoir créé se programme sous CVI 7.1.1, j'aimerais le passer en DLL pour le faire fonctionner avec TestStand.
Je vous joint mon petit bout de programme.
Merci par avance.

TestStand don't unload handle in a DLL after step is executed and unloaded

Hi,
Sorry for the 'Google' English. I hope you can understand my problem.
I developed a DLL (in C, under Visual C++.NET 2003) to program board by Ethernet. Then I developed VIs (LV 7.1) for this DLL. It's work very well.
I adapted these VIs for TestStand 2.0.1 (Test Data indicator and Input buffer command - with the good connector). I had sometime error -18002 (Server close VI) then I configured steps so that TS load them dynamically and unload after the steps execution.
With this step configuration, I can unloaded an Access file opened in a VI.
In the DLL, I open another ASCII file then I close it before go back under LabVIEW. When I launch the VIs without using TestStand ('Edit code' and run under LV), I can launch the programming several times. But if I use 'Run selected step', I can launch only one programming: the file can't be open any more (handle already used). If I do 'run selected step' several times (4 to 5 times), I have an error -18002 and I must close LabVIEW and TestStand for all to free. I tested on another PC which works very well but there too I have the same problem.
How do I have to configure TestStand to be sure that it releases the resource? Thank you in advance for your help.
My NI login didn't work since many months (thanks Laura F. of ni.com to solve this problem) so I posted this message on NI France (SR 7158216). Today, they did not find a solution yet. The support tested the call of a DLL (opening/closing of a file) CVI directly under TestStand without problem. They must test the call of the DLL in one VI, called under TestStand. If somebody encountered already this problem and found a solution, that interests me because my customer want now to have his program speedly. Thanks a lot.
Regards.
PS:
If that can help somebody: LabVIEW does not like 'BOOL' and 'u_char' types in a DLL: the DLL works without error but the result is bad. It is to better use 'int' (instead of 'BOOL') and 'unsigned char' (instead of 'u_char') even of they are used in an internal function with the DLL. I must search a long time before understand this problem.

Thanks for your answer

Changer l'executable du PC RT sans redémarrer le PC

Bonjour
J'ai un PC RT (Phar Laps) sur lequel tourne Labview RT et un PC IHM ( Windows) liaison TCP/UDP entre les 2 PC
D'habitude on utilise un startup.exe qui est lancer des que le PC RT est allumé.
Ce que je souhaite faire c'est de pouvoir changer l'executable qui est exécuté sur le PC RT sans à avoir à redemarer celui ci
Exemple je lance sur IHM un VI (version 2.0) celui ci alors charge sur le PC RT la version RT qui correspond (sans que le PC RT redemarre)
Est-ce-possible ?
Merci

Bonjour,
Le startup.exe est obligatoirement booté au démarrage, vous ne pouvez pas le modifier sans redémarrer. Vous pouvez néanmoins toujours passer par le projet LabVIEW du PC IHM pour redéployer un nouveau code sans redémarrer.
A noter que vous pouvez aussi faire un VI de démarrage :
