Illegal instruments found
Hi,
When I delete any object in the enviroment, I get the message
"illegal instrument found delete it?"
Can someone tell me what this means?
Greetings,
Michiel
The problem is an address conflict. To answer your question at the end, yes, if the GPIB board has a particular address, it is not available for any instrument connected to the controller. All controllers/devices must have a unique address.
I don't remember how the NT configuration utility worked. It is possible that the GPIB configuration utility automatically configures GPIB1 for PAD1 and GPIB2 for PAD2, etc. In general, you should always configure your GPIB controller to be at primary address 0 and have your instrument(s) be configured for an address in the range 1-30.
The GPIB configuration utility lets you choose the GPIB number AND the GPIB primary address separately. Therefore, if you GPIB controller is GPIB1, go into the configuration utili
ty and configure it be at PAD0. Then everything should work.

Using PCI-GPIB card with NI-488.2 version 1.6 (or 1.7) and Windows NT 4.0:
- If a GPIB instrument is at GPIB address 1 on PCI-GPIB configured as GPIB1, this instrument is not found using N.I. "Scan for instruments" utility. If I change this GPIB instrument address to 0 or anyone from 2 to 31, the utility can find the instrument.
- Same observation if I connect a GPIB instrument at address 0 on GPIB0, or at address 2 on GPIB2, etc.
Is the PCI-GPIB card number used to configure it is then no more available for the address number of any instrument connected to this bus?

PXI-4070.jpg 42 KBHello,
Is it possible to take another picture of MAX? That one is very pixilated and I can't quite make out the configuration/error. Does the chassis show up? Every now and then MXI compatibility software is needed for certain BIOS versions so this may be the cause. Did the system work ever before?

Hey i've this button on my applet that when clicked passes text entered in a textArea to a seperate class,then shows the result (after the class is finished with it), at least thats what its supposed to do. What happens is that a flock of errors occur. Can anyone spot the problem

podgerIt looks like it parses a mathematical expression represented as a String with up to three variables (x, y, z), and will substitute x, y, and z with whatever values you give it. What is your "text" (value of "first") that you are trying to parse?
Eventually, you probably want to have text fields for the user to enter x, y, and z, parse those text values as doubles, and pass those to your ParseMe instance by calling: parser.value(x, y, z);
What happens if you type the following in the text field named "text1"?
x + y + z -
Error when installing Form Manager.
Hi all,
I'm trying to install Form Manager v. 7.0.1. When I run the configuration manager, the progress gets to 12% then displays the error code "LCMerror101" with the message "Livecycle module pdfagent-client could not be copied to working directory".
Does anyone know what this error means? How can I work around it?
I know the issue isn't related to disk space (20+ gigs free) and I'm using the administrator account to install. Any suggestions or tidbits of info would be much appreciated.
Thanks,

Ultrabeat in Logic Pro X is missing drum kits
Hi,
So recently, I got Logic Pro X because I've been meaning to try producing house music with it. I was introduced to Ultrabeat in some tutorials saying to click the dropdown menu (at the top) and select 01 drum kits and choose Trance Kit 02. However, when I click the dropdown menu, I seem to only have 8 samples in the drum kit and none of them sound good at all. Why do I have only 8? I've seen other discussions where people have up to 25+, is this something that I can download from the additonal content? And if so, what is it called?
Many Thanks!

The struggle of creating a Custom ClassLoader for Native libraries
Hello Everyone,
I'm having a really hard time writing and using my own ClassLoader in a Java Applet.
Context :
As the this link shows - http://codethesis.com/tutorial.php?id=1 - loading and especially unloading native libraries through Java requires defining our own ClassLoader, and use it to instantiate a class loading a library. When the class using native libraries has finished execution, setting all references to the classloader and calling the garbage collector will cause the native library to be unloaded. The class to load within the custom classloader is thus read byte after byte from the jar and defined using the Classloader.defineClass(..) function. So that's what I did. But I've got two problems.
Problem 1 :
On one single machine over 15 tested, the magic number of a given class read from the Jar using Applet.class.getResourceAsStream(classname) takes a value different from CAFEBABE and the defineClass function then throws an "Incompatible magic value" exception (see below). The workaround I found is to force the first 4 bytes of the byte array read from the class with CAFEBABE. But I still would like to understand why it takes a different value on this machine.
Exception in thread "thread applet-MyApplet.class-1" java.lang.ClassFormatError: Incompatible magic value 409165630 in class file Reader
at java.lang.ClassLoader.defineClass1(Native Method)
at java.lang.ClassLoader.defineClass(Unknown Source)
at NativeClassLoader.findClass(Unknown Source)
Problem 2 :
On windows, the NativeClassLoader works perfectly, but on Linux, I'm getting a java.lang.VerifyError (see below).
Code is compiled with java 1.6.0_06 on windows XP. I tried to remove everything related to native code (remove .so load), the same error is raised.

I am trying to obtain the PXI resource name "PXI1Slot2" programatically.
How to obtain object handle whch viGetAttribute() requires?
viOpenDefaultRM (&rsrcHandle); returns ViSession.
Is there a attribute to obtain the Slot number?
int CVICALLBACK FindResources (int panel, int control, int event,
void *callbackData, int eventData1, int eventData2)
ViSession rsrcHandle;
ViUInt32 numFound;
char InstrDescriptor[256];
ViFindList MyFindList;
int i;
int chassisNumber;
switch (event)
case EVENT_COMMIT:
// First, open a VISA session.
viOpenDefaultRM (&rsrcHandle);
// Now, do an initial search. viFindRsrc returns the instrument descriptor
// of the first instrument found and the number of total resources found.
viFindRsrc (rsrcHandle, "?*PXI?*INSTR", &MyFindList, &numFound, InstrDescriptor);
viGetAttribute (rsrcHandle, VI_ATTR_PXI_CHASSIS, chassisNumber);
// When finished, close the VISA session.
viClose (rsrcHandle);
break;
return 0;
Solved!
Go to Solution.I am working to get something that would identify the existence of the PXI or PXIe, or lack of existence on the system where my app is running.
This looks promising, but throws all sorts of error when I run it.
First, let me say I have an app that runs on a PC, PXI or PXIe system. The PXI has an embedded controller, the PXIe has an MXI Express controller.
I would like to have something that would verify the chassis that I have.
So, I'm using the code from above:
// First, open a VISA session.
viOpenDefaultRM (&rsrcHandle);
// Now, do an initial search. viFindRsrc returns the instrument descriptor
// of the first instrument found and the number of total resources found.
viFindRsrc (rsrcHandle, "?*PXI?*INSTR", &MyFindList, &numFound, InstrDescriptor);
viGetAttribute (rsrcHandle, VI_ATTR_PXI_CHASSIS, &chassisNumber);
// When finished, close the VISA session.
viClose (rsrcHandle);
viFindRsrc give an error "insufficient location information or the device ir resoure is not present in the system"
viGetAttribute gives an error "the specific attribute is not defined or supported by the reference resource" -
hi,

but when i dl'd the 617 drivers all i get is a unknown VISA device?
anyone got any experience with this? i could not find anything on the
subject in the lv manuals.

ok, from the top:
I have LabView 6.0 installed, running MAX 2.0.3.6 and NI-488.2 driver
1.60 on Windows ME.
I installed the GPIB-PCII and windows installed it at a certain IO
adress. I set the jumpers for this IO and when I then scanned for the
instrument I found 'something that I could communicate with.'
I figured the GPIB should use IRQ and DMA so I reinstalled the card
until MAX were satisfied with it using DMA and IRQ.
I then created a ke617 folder under instr.lib and put the ke617.lib
and dir.mnu files there.
now, in MAX, i cannot find an instrument when I scan for it, and the
'unknown VISA resource' pops up.
I'll try to upgrade max and the NI-488-2 driver and se what happens.

I've defined a BIP data set using an OBIEE data model. I can change the column Aliases in the Query Builder - Conditions screen. They show up in the SQL Query box on the Data Set page. But if I go back into the Query Builder, the aliases are all gone.
Can someone please confirm this bug, or tell me what I'm doing wrong? Before you ask, YES, I'm saving immediately after every step.
I'm also periodically (but not predictably) getting an error popup that says "Illegal character found in the alias". This happens from time to time when I click on an Alias column which I haven't even touched previously - it's the default Alias from the column name. Any suggestions on that little irritant would also be welcome.Hi
I think that BIP issues the logical sql to the BIServer. BIServer then retrieves and formats the data into XML and sends it back ie the aliases are at best ignored by the BIServer and might be what is causing your intermittent error.
Ill try and confirm with the dev team

Hi,
I am preparing for 1z0-050 exam to get 11g OCP. I am thinking of buying 'Transcender' - 1z0-050 Practice Exam.
Has anyone used these practice exams and Flash Cards from Transcender for 1z0-050? If yes, do you recommend the material from Transcender?
I have used the Transcender practice exams for 042, 043 and 047 in the past and I found them very useful.
However for all those exams I used a very good Study Guide to supplement the Practice exams.
For 050 exam, based on the Web Search there are only 2 books, Sam Alapati and Freeman. Reviews for both the books are not that great.
Looks like Sam Alapati book has lot of errors.
Can someone please post there experience regarding the Transcender practice exam for 1z0-050?
Thanks in advance.I used a practice test from SelfTest Software, which is produced by the same company, Kaplan. I thought their practice test for that exam was very good. I only have one complaint: Some of their referenced materials (websites, etc) were illegal materials found on sites like docstoc. I hope they've removed those. Anyway, I also had heard that Alapati's book was not so good, but it was the only book I used. When I heard that, I decided to glean through the book quickly & try to learn elsewhere. This site is helpful:

I have a Class called Execute which runs as a thread. If this fails, then I want to show a JOptionPane from the main thread saying it failed (this works), but also I want to create a JOptionPane within the run() method of Execute stating the reason for the failure.
I can not put a JOptionPane directly inside the run method 'cos it doesn't get rendered correctly, so I run this in it own thread. Only trouble is that now I have two modal dialog boxes appearing simultaneously; what I want is to have them appear consecutively. I have tried to join the thread that creates the pop-up but then it does not get rendered. Any ideas? I have posted an extract of the code below for testing
public class Execute implements Runnable {
File success = new File ("/ukirtdata/orac_data/deferred/.success");
File failure = new File ("/ukirtdata/orac_data/deferred/.failure");
success.delete();
failure.delete();
try {
success.createNewFile();
failure.createNewFile();
catch (IOException ioe) {
logger.error("Unable to create success/fail file", ioe);
return;
SpItem itemToExecute;
if (!isDeferred) {
itemToExecute = ProgramTree.selectedItem;
logger.info("Executing observation from Program List");
else {
itemToExecute = DeferredProgramList.currentItem;
logger.info("Executing observation from deferred list");
SpItem inst = (SpItem) SpTreeMan.findInstrument(itemToExecute);
if (inst == null) {
logger.error("No instrument found");
success.delete();
return;
String tname = QtTools.translate(itemToExecute, inst.type().getReadable());
// Catch null sequence names - probably means translation
// failed:
if (tname == null) {
//new ErrorBox ("Translation failed. Please report this!");
logger.error("Translation failed. Please report this!");
new PopUp ("Translation Error",
"An error occurred during translation",
JOptionPane.ERROR_MESSAGE).start();
success.delete();
return;
else{
logger.info("Trans OK");
logger.debug("Translated file is "+tname);
failure.delete()
return;
public class PopUp extends Thread implements Serializable{
String _message;
String _title;
int _errLevel;
public PopUp (String title, String message, int errorLevel) {
_message=message;
_title = title;
_errLevel=errorLevel;
public void run() {
JOptionPane.showMessageDialog(null,
_message,
_title,
_errLevel);Comeon,
Someone must have some idea. I have tried making popup extend JOptionPane and implement Runnable, added a window listener which sets a boolean popDisplayed on windowOpen and windowClose, but this gets me nowhere (I have a Thread.sleep in the code as well) -
Hello!
I have an error in T-code DB13 checkDB in my BI system
Illegal value ' ' found in DBCHECKORA field 'CHKVAL' for key 'PROF LOG_ARCHIVE_START' - ignoring the record
What should i do about thisHi Robert,
Check you oracle parameters in your spfile or init<SID>.ora, value of LOG_ARCHIVE_START should be either TRUE or FALSE. Also check the value of the Database check condition on DB17 match the value on the profile.
