A problem about build project fail...
Hi all, I'm fairly new to iPhone programing and now get a problem about build project fail. ><
I've downloaded a couple of sample codes from Apple web site and build them, but there are some errors messages as below...
Could some body help me to handle this problem?? I'll be very appreciated~
================================ Error msg of "MoveME" sample ============================

Error -17704, Build project failed in CVI
I'm using CVI7.0 with TS3.0.
When I configure the CVI adapter to be in debug mode, the TS uses tscvirun.prj to run an additional instance of the CVI code for debugging. As soon as TS finishes to load this project I get the run-time error:
Build project failed in CVI for the project c:\....\tscvirun.prj.
Error Code: -17704; CVI ActiveX automation server command failed.
Any idea where to start looking?
p.s. This entire project was copied from another pC where I don't have this problem. I did a lot of comparing between configurations of the two pCs but found nothing.
ThanksRafi2003 -
Does the original tscvirun project that TestStand installs work with the example on the failing system?
To validate this you may need to repair TestStand so that the tscvirun files are refreshed and try the examples to make sure things are working properly on the system before attempting to use the files from the second system.
If you rerun the insaller, one of the available options will be to perform a repair.

Problema con Building Projects
Hola amigos.
Soy estudiante de Ingeniería mecatrónica, y hace un tiempo que trabajo con LabVIEW. El problema que me ha surgido es cuando trato de abrir el Building Projects se me cierra enseguida el MAX y ya deja de todo de funcionar; luego toca cerrar el programa a las malas con el administrador de tareas.
Tengo la versión 8.0 del LabVIEW, y mi sistema operativo es Windows Vista Home Basic.
Alguien ha tenido éste problema antes?
Gracias por atenderHola,
Hay dos maneras de corregir esto error:
-Corra el "Mass Compile" de el LabVIEW. El fija los errores que el LabVIEW pueda tener. Mira el enlace abajo:
http://digital.ni.com/public.nsf/3efedde4322fef19862567740067f3cc/aa97c01071d7cf678625695100582f40?O...
-Si los errores continuaren, usted debe reinstalar el LabVIEW.
Si los errores de todo modo continuarem por favor me contacte.
Cordiales Saludos

Some problems about Upgrad project
Dear,
I have some question for Upgrade project.shi
P1: in form ZSD_EXPORT_FECO, check texts, Windows F005 has an error :
/: AND &V55EFECO-REMA_TEXT2& = ' '
Unknown command
I dont know how to correct it.
P2: in program ZFUMSV00, the source code is sy-repid = 'RFUMSV00'.
In 700 version, it checks error: the field sy-repid cant be changed.
But, in 46c version, it is OK.
I dont know how to correct it.Hi
check this doc
While doing Upgrade You have to aware of all related program like BDC's , Screens related errors and all dictionary related problems.
Some function modules may become obsolete, and some screens will change
and some new fields will be added in the new versions etc.
Also take care of SPAU and SPDD tcodes.
You should be able to know about Unicode concept in sap.
check this
http://www.thespot4sap.com/upgrade_guide_v2.pdf#search=%22upGRADE%20STEPS%20-%20SAP%22
also chk these 2 notes in service.sap.com
Technical Upgrade is only a version upgrade without any functionality changes.
The objects that are needed to be upgraded are:
Includes
Function Groups / Function Modules
Programs / Reports
OSS Notes
SAP Repository Objects
SAP Data Dictionary Objects
Domains, Data Elements
Tables, Structures and Views
Module Pools, Sub Routine pools
BDC Programs
Print Programs
SAP Scripts, Screens
User Exits

Strange problems about my projects(efficiency,event structure,queue)
hey,guys,i am a labview user from china,so forgive me about the chinese words of my projest. i found something wrong with my work. .
there are two functions in my "While loop", the first one depends on "queue" and is to get information from UART, the second one is "event structure" to send information through UART. my problems:
1. i can not stop while loop by pressing "停止“, and i find two ways to stop it. first, i press"停止”,then, i press any buttons that can trigger "event structure"twice, at last, while loop can stop.the second way, i press buttons for "event structure" one time, then "停止”， and then the same button for"event". it also works
2.my work does not run efficiently. you guys can try. once you press buttons for "event structure", it responses very slowly,and if you press many times,the whole program seems like suspending.i have added a LED named test at the front panel, it should light once you press "运行“. and it also shows how slow the whole program is.
i have attached my work, and my main vi is "串口通信 主VI".
can any body give me some suggestions? thanks a lot
Attachments:
Uart.zip 140 KBYour event structure will execute exactly once per loop of the main loop, thus the other three loops must stop before handlig the next event. You will also get a race condition between the top loop and the events when writing.
I'd put the top loop as the timeout case in the event and place the loop around the event for starters.

so i will briefly explane u what is my project goal. my project goal is to give a solution to communicate several systems by upping webservices which are running seperatly on seperate servers by several technologies.
To do this i want to apply "grid computing on peer to peer architecture".
so plz guid me is this possible to do with grid computing andif is not tell how can i do this( to embeded several systems upping web services ).
also guid me how to get star to get best practice of grid computing?

This issue is coming to only few members out of 10000 members.
Note: For the same user, can able to do in other machines. only the problem in his machine. Have ran the office diagnostics, but still the problem persists.

My home building project is just about finished. Unfortun...
My home building project is just about finished. Unfortunately, there we won't be able to use either a cable or Qwest DSL service to connect to the internet because of where we live. We do, however, get a great cellular phone signal.
The support guru from T-Mobile suggested that the Linksys WRT54G3G-AT might serve me well as it would bring in internet connection and serve as the network to distribute the internet signal to many devices both wirelessly and through ethernet cables. I have a new desktop Dell (with Vista OS), an older HP desktop and Dell B120 Inspiron notebook (with XP OS), and also an XBox (not 360) and Wii. I also want to network the computers. Before investing and trying to set all this up, though, I really want to make sure that I'm headed in the right internet connection direction. Anybody have thoughts on this?
Also, I have T-Mobile cellular phone service already. I noticed that the WRT54G3G-AT web site mentions AT&T wireless. Would I have to use AT&T wireless ($60/mo) to use the WRT54G3G-AT or can I use a cellular internet card from T-Mobile ($20/mo)?
Many thanks to any thoughts and help people of the forum can provide.
figI think you need to use AT&T service to use WRT54G3G-AT ...

Hello abapers, right now i'm writing a paper for the company that i work, this paper it's related with SAP Projects, i would be so glad if you let me hear your comments about What are the reason that you think that makes SAP Projects Fails? It an IT related stuff.
I want collect all your comments based on your experience implanting SAP Projects. This is important to me because a will see closer the common problem around the world and will not localized my paper use only issues that i may know.
Regards,
Carlos.Hi Carlos,
You have touched upon a major topic here and I am not sure if you can ever close this post. But let me give it a try. Let me try to put it into perpective by discussing the topic following the project lifecycle.
Now any ERP implementation starts with a requirement at the top level to refine their IT landscape to better support the business. Then you go out to search for the best tool to do that. That can be your first point of failure, if you don't identify the right fit(ERP software) for your organization. I was on a SAP project where they thought SAP is the best fit for their business, but 6 months into the project, they realized that even though SAP is the best ERP software around, it didn't fit their needs. They scrapped the project and went for custom development in Oracle.
Then comes your choice of the implementation partner. A big implementation like an ERP implementation cannot be completely sourced with inhouse resources. You meed a implementation partner who has the experience to steer you though the implementation and make it successful. Now this is not specific to SAP, but with SAP you have to be even more careful on this aspect because of the costs and time involved.
Once you have identified SAP as the tool and identified your implementation partner, you then venture into the identification of implementation team from your organization. Depending on which modules you are implementing, you want to identify teams that have a very healthy mix of business knowledge, experience in specific areas of the company's business functions, technical expertise that can easily adopt and learn new software quickly. If your team is not chosen wisely then there will be a makor gap between the requirements and their translation into implementation.
Defining the scope of the project is also important. By doing this, you will identify which processes you will implement in SAP and as a result which applications you will replace with SAP and which applications you will interface with SAP. If you fail to correctly identify this, then the project will fail.
An ERP implementation means a lot of change and that means all your end users, your implementation team, your management and basically everyone should be ready for it. This involves a major investment(not necessarily monetary) in change management. There will be a change in the way you do things and everyone should be ready for it. If they are not, then there will be a failure in effective use of the tool thus effecting its utility to the organization and the productivity of the employee.
After you are past the requirements phase and team preparation phase, you enter the design phase. The project can make or break depending on what happens in this phase. This is where the implementation team goes out to define the business processes, identify requirements and translate them into configuration and development specs etc. If any of the tasks here go wrong, then the final product will be a failure.
In the development phase, it can be any or all of the factors like lack of technical expertise, lack of usage of best practices, lack of standards, lack of supporting infrastructure etc.
Other factors include, support from top management and business process owners for the project(they should be the stakeholders in this), political aspects of the client place, integration requirements etc.
As Anand pointed you first need define 'failure'. In a project as big as an ERP/SAP implementation, a complete scrapping of the project can be a failure, or not completing the project on budget, on time could be a failure or not being able to deliver one specific critical functionality can be a failure. So as you can see, the definition of the failure itself can be so different for so many implementations.
Even though your question is specific to SAP, my answer is more generic and applicable to any large scale project. SAP inherently has no in-built faults that make a project a failure. As long as you keep all the above factors in control, you should have a successful project.
Hope this discussion continues.

Annoying Problem when building under Eclipse
Hi all,
Please, does any one faced this problem with Eclipse (2.1.x) using JCOP :
some times when I try to build the project, using menu Project->Rebuild Project, I get an error in the Task view saying : "The project was not built due to "Problems encountered while deleting resources.". Fix the problem, then try refreshing this project and rebuilding it since it may be inconsistent. ".
Often it's solved if I make a "Rebuild all" but sometimes it fails and I still get the error.
I can get rid of it, but almose by trying and trying again, and I want to know how to be able to build my project without this problem.
ThanxYou can fous to left side "Package Explorer" sub-window for your project, and press "F5" to refresh,
after that retry to build project again. -
Problem about selecting waveform in waveform graph
Hi all:
I am developing a project by Labview. Now I meet a problem about selecting the waveform in the waveform graph.
I am not sure whether it is possible about my idea.
for example:
In the waveform graph, the different waveforms from a couple of channels are displayed. and then I want to select one waveform of them, and corresponding data about this waveform are shown.
Thanks so lot

1. can I zoom in and out in that "waveform graph"??
You can do this using the graph palette. Just make it visible. The middle control allows you to zoom.
2. can I display the plot array or plot index that I select in the waveform graph?
You can connect the same wire that goes to the ActivePlot property node to an indicator.
3. I build a sample codes for my project, in which , I used a random number generater to simulate a DAQmx data collection, and generate a overlapping waveform in the waveform graph.
but it seems the program is not stable, when i first run the codes, it is ok, and I can select the plot what I want. but after I stop and restart the program, there is error message about "Property Node".
it seems something wrong about the "waveform graph properties"
I attached my codes here, anybody know what wrong about it?
For some strange reason the property node is "messed up". I've seen this happen sometimes with graphs. I don't know what causes it, and the only way I've found to fix the problem is to delete the graph, put a new one on the front panel, and recreate the property nodes. I've typically seen this happen when copying code from another VI that has a graph with property nodes, as I suspect you did. If you delete the graph, put a new one on there, and recreate the property node you should be OK.
That said, a few comments regarding the code:
The architecture seems to be a mish-mash of operations, and I'm thinking that you probably want to look at using a producer-consumer architecture. Your producer loop responds to events, and the consumer loop does your DAQ collection.
You have a race condition with your use of the "size(s) 2" local variable.
Avoid right-to-left wires.
The method of creating your arrays seems convoluted. However, since you said you will actually be getting the data from a DAQ system, the actual project code will likely be considerably different. -
Some problems while building tuxedo executables (OS/390 - Open MVS)
Hi,
I have a both strange and serious (at least it seems serious to me) problem
with building tuxedo executables.
I'd like to link the object files with a library I created (say libmylib.a),
and the only place I know about to pass some info to the tux builders is the
env var CFLAGS. In my case the CFLAGS looks as follows: "-L
/u/myhome/myproject/lib -lmylib", but the linker protests, saying that the
symbols from object files placed in my library can't be resolved ;(.
On the other hand if I just take the object files out from the library and
try to link the executable placing all of them explicitly in the command
line everything goes smoothly.
HEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEELP...
Regards
Chris

An old and difficult problem about "UnsatisfiedLinkError"
Hi dear all,
I have been struck with the problem about "UnsatisfiedLinkError". I have a c++ class HelloWorld with a method hello(), and I want to call it from within a java class. In fact, I have succeeded in calling it on the windows platform. But when I transfer it to linux, the error "UnsatisfiedLinkError" comes out. I have tried to take the measures as Forum has suggested, but it failed.
The source code is very simple to demonstrate JNI.
"HelloWorld.h"
#ifndef INCLUDEDHELLOWORLD_H
#define INCLUDEDHELLOWORLD_H
class HelloWorld
public:
void hello();
#endif
"HelloWorld.cpp"
#include <iostream>
#include "HelloWorld.h"
using namespace std;
void HelloWorld::hello()
cout << "Hello, World!" << endl;
"JHelloWorld.java"
public class JHelloWorld
public native void hello();
static
System.loadLibrary("hellolib");
public static void main(String[] argv)
JHelloWorld hw = new JHelloWorld();
hw.hello();
"JHelloWorld.cpp"
#include <iostream>
#include <jni.h>
#include "HelloWorld.h"
#include "JHelloWorld.h"
JNIEXPORT void JNICALL Java_JHelloWorld_hello (JNIEnv * env, jobject obj)
HelloWorld hw;
hw.hello();
All the files are in the same directory and all the processes are under the dirctory:
1. javac JHelloWorld.java
2. javah -classpath . JHelloWorld
3. g++ -c -I/usr/java/jdk1.3/include -I/usr/java/jdk1.3/include/linux JHelloWorld.cpp HelloWorld.cpp
4. ld -shared -o hellolib.so *.o
5. java -cp . -Djava.library.path=. JHelloWorld
Exception in thread "main" java.lang.UnsatisfiedLinkError: no hellolib in java.library.path
at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1349)
at java.lang.Runtime.loadLibrary0(Runtime.java:749)
at java.lang.System.loadLibrary(System.java:820)
at JHelloWorld.<clinit>(JHelloWorld.java:7)
Tried another measure:
i) export LD_LIBRARY_PATH=.:$LD_LIBRARY_PATH
ii)java -cp . JHelloWorld
The same error came out as above.
I really don't know what is wrong with it.
Would you like to help me as soon as possible?
Thanks.

JohnsonHi Fabio,

I have problem in my project, please Help me, urgent
have problem in my project.
When i start using project, i recive a errore in flash player
if it possible troubleshooted for me
Problem fileThe problem is that you have left paper on the floor near the
wastebasket.
Please you have to do a little of the work yourself.
First, post a topic that has a title regarding your problem.
That way people who know about that problem will be more likely to
take a look.
Second, don't just say you have a problem and receive and
error. Shay what kind of problem and tell us what the error says.
Third. Most people won't download a file from any random
stranger off the net. So don't expect that is going to explain it.
Fourth, even if the file does explain it, why should a
stranger have to do all the steps that you should have done?
Fifth, do a little work yourself, what have you tried to fix
it?
Sixth. Just because it is urgent to you doesn't mean it is
urgent to everybody else.
So try some of these things and post back. -
Problem about updating to Mac OS X 10.5.3
Hi there,
I just bought my Macbook two months ago. I encounted a problem about updating it to the latest version of MAC OS X. The system reminded me to restart, I proceed. Everythig looked just fine until a poping up window shown "Mac OS X 10.5.3 pacakage can not be validated". Dose anyone know what did that mean? How can I update my little mac?Hi Hummer,
First, welcome to Apple discussions.
To answer your question, your computer checks all downloaded updates before installing them. It does this to make sure it's got the entire file and that the update will install correctly. The fact that validation fails on your machine probably means the file did not download correctly.
To install 10.5.3, simply go to this website, download the "10.5.3 combo update" and then run it on your Mac: http://www.apple.com/support/downloads/
