Is it a bug in IMAQ or what??

Hi All
I am using LabView 6.1 along with IMAQ 2.5.1 for a system that I use to capture images while the camera is moving in X, Y directions. The program was set so that different scans can be made to measure specific sizes of aggregates in each scan. the program will save the two images. an original images as captured by the camera and a processed one which is exposed to different filyering process. Of these filters that were used is to keep particles within specific size and remove any other particles or objects from the original images. What happens is that this filtering work fine most of the time but when analyzing small particles it becomes showing un real objects in the saved image. these objects are not real particles. These object
s would show in places in the processed image where there are nothing in the original image (blank space). Also if the filtering was functioning properly it would remove these small objects because these objects are smaller than the size range needed. So What could be the problem. Is it a bug in IMAq that the filtering is not functioning properly? or what could it be? See attached VI. you can undestand what I am saying. could there be a solution for this

hi,
You can try to create two or more image buffer to two different images,one for original image and one for processed image.From your VI ,you only use one image buffer.It maybe make error .

IMAQ AVI - What is "frame read lookahead"?

Hi,
I'm using The IMAQ AVI Read Frame function, and just wondering what the "frame read lookahead" input actually does. The documentation is very vague.
Thanks

What is vague about it? What additional information do you need?

Generating a List of References in FM12 to include External Cross-References and Imported Graphics, but no Imported Graphic references show in the LOR. Is this a bug in FM12 or what am I doing wrong?

and has always generated the list of references just fine. Now in FM12, the LOR no longer will give any references for the Imported Graphics. I have even tried creating a new chapter from the FM12 templates, adding the chapter to the front of the book, and allowing FM12 to use that file as the template for the LOR. Still no success - it will not give any references to the Imported Graphics in my chapter files. Is this a bug in FM12? Is there something different about FM12 that would cause this not to work with existing FM11 files??? Please help, I need this resolved and working.
Thank you,
Beverly

Arnis and Jeff,
Thank you both very much for your assistance. I was able to figure out why the Adobe Application Manager kept failing on installing the patches. Idiot me didn't unzip them first. Once I unzipped the patch files, the installer worked fine. Both patches are now successfully installed; my FM version is now 12.0.2..
To answer some of your questions:
Yes, I have administrator privileges on my PC.
Yes, I had all of the files in the book opened when I generated and/or updated the LOR file. So that was not the issue.
With the patches installed, I opened a book and all of its files. I updated the LOR and all works fine – it gives me all of the Imported Graphic references. So there must have been an issue with that release of FM12 (12.0.0.329), which was fixed with the patches.
Again, thank you both for your help!
Best regards,
Beverly

JFileChooser crashes JVM - bug basically ignored. What can I do?

See:
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=7160713
The bug has been marked as incomplete,needs more info, and "Low Prioroty" - Yet there is no mechanism to provide any more information. There is no way to add comments, or vote. The bug brings down the entire JVM with a native crash and it is trivial to reproduce.
I would provide any information that is asked of me - but I need a way to do it. I think I got an email request for info (It's been a while now), but replies to the email bounced, and as noted above the bug page has no way to give feedback.
Use any JFileChooser, click on the "Details" view. Then start clicking on column headings... after a few clicks the JVM crashes. Tested again with 7u6 - still crashes.

This reproduces the problem more reliably for me.

2.01 Did not fix long backup bug for me. What do I need to do?

Hi,
The update has not corrected the long backup time bug for me. Started a backup 30 mins ago and based on the progress bar it will run for at least another 2.5 hours. I don't understand how it can take that long to backup less than 8GB of information. Do I need to change a setting or delete old iTunes backup files to get this process working correctly. Most of the other bugs I encountered with version 2.0 seem to be resolved but this backup bug is a time waster. Do I need to take the phone and my mac to the Apple store and have them look at it?
Thanks,
D

You can cancel the backup process by hitting the x in the progress window and it will go directly to the sync if it is taking it too long.

HELP ! A FATAL BUG ! ! ! What`s wrong with the SATA port ? ? ?

My MacBook (MD103) got a serious bug here, PLEASE HELP ME !
I changed my main drive to a Crucial 256GB SSD and memory to Micron 16GB, and I also removed the optical drive. The optical drive has been replaced by the original Toshiba HDD. Then, the question has came out! The OS hourly report Errors and restart. Finally, the HDD icon will disappear from Finder and the drive will be changed into a read-only disk (Under the Windows OS installed by BOOTCAMP). Then, I have to format the drive.
BUT the question still happen AGAIN AND AGAIN！ Though, I changed the Toshiba Drive by a WesternDigital one (Model. LPVT 500G), which is the most energy-efficient notebook HDD, BUT the question take place AGAIN when I listening an iTunes music ! ! ! (The music tone was reapted again and adain, and the OSX was shut down in a sudden, without any operation)
I searched some information and did some attempt. The OS can work well when I change the second drive by a old 250GB HDD, but I really can`t use such a slow and small drive for work, and I have to pray for my data every time when I press the power button. So, please help me! Improve the SATA port power management or someting else, THE BUG CAN BE SOLVED BY YOU, THE GREATEST ENGINEERS.
Please let me know the progress, THANK YOU ! ! !

Firstly, Thanks!
I've checked it and if the question didn`t occur, the disk can work well. The I/O speed can reach 113MB/s. And someone said it causes by SATA port power supply.

Directory creation Bug or Error or what?

Hey - okay, I'm still using version .9, not .10 of Tiger. A few times a couple of layers deep in a directory, I've created a new directory/folder - name it "one". I've then copied RAW camera files into that directory. I'll then back out, make sure the data is there - it is. Then I go back to add a "two" directory. I'll back out to go find the next RAW camera card, copy it, move through "finder" back to where "two" should be, along with "one" and there are two "two" directories and the files can't be found.
Why would such a thing happen? And have I been clear with the problem?
Thanks -
Glen

Yes, I think I know what you are doing, and have seen several instances that sound like the same bad behavior, see this recent discussion:
http://discussions.apple.com/thread.jspa?threadID=1066455&tstart=50
Like rccharles in that thread I too would like to know what shows up in Terminal. I would also like to know what happens if you relaunch the Finder (you can do that by holding down the Option key, then click on the Finder icon in the Dock and select Relaunch from the menulet). The OS X Finder has been rather infamous through several different iterations for having bizarre updating problems, perhaps this is a new version of an old problem.

Hey friends, iphone keeps powering off diagnostics says bug 115 anyone know what it is

Bug_type 115

Thanks for the suggestions!
Except I tried all those before I even made this topic lol, but thanks!
I Already popped out the Sim Card & let my phone sit without it for a few minutes then put it back in. Sometimes it will work again & it will say it recognizes the SIM Card but more times then not it still says it cant recognize it! So I have to take it out & reinsert it multiple times.
& I have done a complete restore 2 times & a back up restore 3 times. Nothing seems to be working.
I am planning on going to the Apple Store this week, wish me luck!
But keep the suggestions coming if you have any, I'd appreciate it!

Why can I participate in surveys and post questions, but whee FaceTime or use messaging, I can't. I'm told I have no internet connection...but I do have it...do I have a bug is this a what I call a windows nightmare?

Why can I participate in surveys and post questions, but can' t use FaceTime or messaging without being told I have no internet connection? However, my iPad shows full internet connectivity.

Apple has released a document which is reported to address the recent FaceTime issue.

IMAQ vision bug in several IMAQ vision functions

Some IMAQ Vision functions malfunction if you use the source image as the mask. I keep running into this bug in IMAQ Vision, some Vision functions exhibit this behavior, and some don't. It is not documented in the function descriptions. Even if it were, it would still be a bug. Example:
1. Create a U8 source image that contains some zeros and some nonzero values.
2. Wire the image into the source input and mask input of IMAQ Quantify and return the % value of the global report to see what percentage of pixels are nonzero.
The answer is wrong. If you copy the image into a separate image first, and wire the separate image into the mask input, you get the correct answer. See attached VI for edification
Cheers,

Multiple IMAQ version on single computer

I have a number of cameras that I work with - mostly CameraLink, but one LVDS. I'd like to be able to develop and test these from one machine, but there is a bug in more recent versions of IMAQ that cause the camera data to be delayed and/or shifted (I found this out through e-mail correspondance with one of NI's support people). For the CameraLink, I'd like to use the most recent version of IMAQ. What would be the best way to have both version accessible on one computer? Can I install them to different user accounts, so they are only accessible to a single user? Would the only way to do this be to dual-boot?
Thanks,
Gard
Solved!
Go to Solution.

Try to install them on different user accounts in single boot system.

as you can see 96.7% of our store is taken up by these mapLN entries. we haven't found any documentation as to what these things are. this is killing one of our BDB stores because in the last 24 hours we've generated around 10,000 new .jdb files when we used to have a few hundred...
we're using je-3.3.74
we upgraded to je-3.3.74 (from 3.3.62) on November 3rd but this particular issue didn't show up until around 24 hours ago.
thanks for taking a look ~j

Hi All,
We've been working on this with the Xoopit folks and I wanted to follow up and post the resolution, since it potentially impacts everyone using JE 3.3.x.
There is a bug in JE 3.3.74 and earlier, in all versions of the 3.3.x product. The fix for this is in JE 3.3.75, which currently is available on request. We haven't decided when we'll update our download site with this updated release. If you would like the updated release, please send email to mark.hayes at the obvious .com (oracle).
Here's the change log entry for the bug, which should explain what you need to know:
Fix a bug that caused the space taken by internal metadata in JE log files to increase over a long period of time. The rate of increase was slow in most cases, but in at least one observed case became rapid after a long time period and after the log cleaner became backlogged. To determine whether your JE log exhibits this problem, run
java -jar je.x.y.z.jar DbPrintLog -h DIR -S
and examine the line labeled MapLN on the left. If the amount of the log taken by MapLNs is 10% or greater, or if you see this number increasing steadily over time, then your application is probably experiencing this problem.
By installing JE 3.3.75 or later, the excess disk space will automatically be reclaimed over time, as ordinary checkpoints and log cleaning occur. If you wish to recreate your database rather than wait for this to occur gradually, you can use DbDump and DbLoad to do so.
We'd like to express our appreciation and sincere thanks to Jules and the other folks at Xoopit who reported this problem and helped us to diagnose it. We would not have found or fixed this problem as quickly as we did without their help.
For reference, the support ticket # for this problem is: #16610
If you have further questions, please reply to this forum post.
Thanks,

Problem with JMenus that Persist - Is this a Java bug?

I am having a problem with JMenus that persist. By this I mean
that my drop down menus persist on the screen even after they have
been selected.
I've checked the Java bug database, and the following seems
to come closest to my problem:
Bug ID: 4235188
JPopupMenus and JMenus persist when their JFrame becomes visible
State: Closed, not a bug
http://developer.java.sun.com/developer/bugParade/bugs/4235188.html
This page says that the matter is closed and is not a bug. The
resolution of this matter printed at the bottom of the page
is completely abstruse to me and I would appreciate any
comments to understand what they are talking about.
The code at the end of my message illustrates my problem.
1. Why should paintComponent() make any difference to
Menu behavior?
2. Is this a bug?
3. What's the workaround if I have to paint() or repaint()?
Thanks
Tony Lin
// Example of Menu Persistence Problem
// Try running this with line 41, paintComponent(), and without line 41
// Menus behave normally if line 41 is commented out
// If line 41 exists, menus will persist after they have been selected

import java.awt.event.*;
import javax.swing.*;
public class P2 extends JPanel {
JMenuItem[] mi;
public P2() {
JFrame thisFrame = new JFrame();
thisFrame.getContentPane().add(this);
JMenu menu = new JMenu("My Menu");
JMenuBar mb = new JMenuBar();
mi = new JMenuItem[4];
for (int i=0; i<mi.length; i++) {
mi[i] = new JMenuItem("Menu Item " + String.valueOf(i));
menu.add(mi);
mb.add(menu);
thisFrame.setJMenuBar(mb);
thisFrame.setSize(400,200);
thisFrame.setLocation(150,200);
thisFrame.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent we) {
System.exit(0);
thisFrame.setVisible(true);
public void paintComponent(Graphics g) {} //Affects menu behavior!
public static void main(String[] args) {
new P2();

Well, my understanding of the way painting works is that a component doesn't UNPAINT itself. Instead a message is sent to the component under the coordinates of the menu to REPAINT itself.
In your demo program the JFrame is the component under the JMenu. The paintComponent() method of JFrame is empty, so nothing gets repainted.
I added super.paintComponent(g); to the method and everything works fine.

Is it a bug in IMAQ or what??
