Why does this program not stop when not highlighted.
When I highlight the execution of this program it runs through and stops. However when I take off the highlight then the program does not quit running. I have encountered this problem on other programs as well. What causes it?

Hello,
Thank you for contacting National Instruments.
I took a look at your VI. I think the problem may be that you are using a Continue if True loop condition in your first While Loop. If you press the stop button wired to this condition or if an error is generated in your VI, that first loop will continue to run indefinitely. Try right clicking the loop conditional and changing it to Stop if True. You may then need to change your Less? function to a Greater? function within that same loop to preserve the intended behavior of your program
I hope this solves your problem. If not, let me know.

Why does the program crash repeatedly when I try and use Sound Cloud

You might already have tried these things, but just in case:
(1) To rule out one of your extensions as the culprit, can you reproduce the problem in Firefox's Safe Mode? That's a standard diagnostic tool to bypass interference by extensions (and some custom settings). More info: [[Troubleshoot Firefox issues using Safe Mode]].
You can restart Firefox in Safe Mode using
Help > Restart with Add-ons Disabled ''(Flash and other plugins still run)''
In the dialog, click "Start in Safe Mode" (''not'' Reset)
Any difference?
(2) If Firefox lags on multiple sites (not responding, slow scripts), try disabling the protected mode feature of the Flash Player plugin. The following pages provide information on how to disable the feature.
* Adobe support article under the heading "Last Resort": [http://forums.adobe.com/message/4468493#TemporaryWorkaround Adobe Forums: How do I troubleshoot Flash Player's protected mode for Firefox?]
* Manual steps: https://support.mozilla.org/questions/968190?page=5#answer-509209
* Batch file to automate the manual steps: https://support.mozilla.org/questions/982093#answer-518078
That takes effect after Flash is completely unloaded; you might need to exit and restart Firefox. -

I rather regret avoiding the OP's earlier post asking how to combine two classes. I looked at the two classes posted and realized the best thing to do was actually to break them into more classes. But I also realized it was going to be a big job explaining why and how, and I just don't have the patience for that sort of thing.
So now we have a Big Ball Of Tar™ and I feel partly responsible. -

Hello René, Thank you very much for your email. I am happy to work with you. I have been working on this all day. I still have not figured out why this is not working. I am Mark Sullivan and Cheri White's Crew Chief/Technical Support for the USA.
The following products are being used:
MacBook Pro,Mac OS X Version 10.7.4, Processor 2.8 GHz Intel Core 2 Duo
Mac iPad, Version 5.1.1 (9B206)
Non of these prodects will upload your site http://www.gordonbennett2012.ch/
I have tried the following browsers:
Opera: Could not connect to remote server,
Safari: no responce
Firefox: The connection has timed out The server at gordonbennett2012.ch is taking too long to respond.
Google Chrome: Oops! Google Chrome could not connect to www.gordonbennett2012.ch
I have had all our crew do the same. They are in different parts of the USA.
And the response has been the following:
North Carolina on PC and Android: Site uploaded
New Mexico on PC and iPhone: Site did not upload on either
New Mexico on PC and iPhone: Site did upload
I have also contacted Mac. Please let me know your thoughts so we can sort this out. In the past I have been able to get your site. Just in the past month I have not been able to. I am getting a timed out error from ALL the above browsers.

Gordon Bennett 2012 Secretariat / Postfach 280 / CH-9650 Nesslau / Switzerland www.gordonbennett2012.ch René Louis / Kirchweg 672 / CH-9650 Nesslau / SwitzerlandThere seems to be a block with the Internet server in the United States as other Internet and cell servers i.e. Verizon and Century-Link DSL work with Mac, Andriod and PC. It just seems to be Mac on Comcast that is not...
Without more data I'm inclined to say it's more likely to be Comcast itself, rather than 'Macs on Comcast'.
For example, do other devices (PCs, Android, iOS) on that Comcast network also have problems connecting? or do they connect fine?
I'd expect that any device at that network has a problem, which indicates a problem with Comcast. It might be their DNS not resolving properly, or them not routing data correctly, but that should be your focus.
Perform a DNS lookup on the www.gordonbennett2012.ch hostname. What result do you get? Is it the expected address?
If that returns the right address, what do you get with a traceroute?
That will test the routing befween your system and the server, and may indicate other problems on the network. -
Why does this expression not work as I'd hoped?
I have a Black Solid 3 with a CC Particle World placed within it. I have some particles set up to run at 0.01 velocity outward from the center of my composition. I've put the following expression on the Velocity setting:
value = thisComp.layer("Audio Amplitude").effect("Both Channels")("Slider");
if (value > 50) 20 else 0.01
The Audio Amplitude layer it is linked to is a auto-keyframe layer created from a .mp3 file - the values that it hits during the most intense part of the song range from 1 to around 85-90.
Why does my velocity setting remain at 0.01 consistently, despite it being clearly evident that the Audio Amplitude layer is going far over 50.
P.S.: If I change the > sign to a < sign, it stays at 20. Why?
EDIT: Okay, it seems the issue was having the variable named as 'value'. Now that it works, it still doesn't seem to work as intended - I'd wanted the particles to move very slowly outward, and then whenever bass was detected, to speed up, until the bass was no longer detected, in which case it would return to a slow pace again, anyone have any idea how I'd go about doing this?
Message was edited by: James WingateOne way is to prepare a "Remap Speed" slider somewhere in the comp that will control the remapping speed, and animate it.
0 = time lock, 1 = normal speed, 2 = speedx2, etc
Then in the time remap property of the layer, set this expression:
s = [pickwhip the "Remap Speed" slider]
t=inPoint; // normal time
T=inPoint; // remapped time
dt = thisComp.frameDuration;
TIME = time-0.001;
while (t<TIME){
T+= s.valueAtTime(t) * dt;
t+=dt;
T;
Ok i reread the original post again, in your case the "Remap Speed" slider could have the expression:
value = thisComp.layer("Audio Amplitude").effect("Both Channels")("Slider");
if (value > 50) 1 else 0.01 // above 50 : normal speed, under : very small speed -
Why does this constantly freeze up when I am in the middle of a game?
I was in the middle of playing a yahtzee game and all of a sudden the game froze up? WHY? I realize this is a free service, but come on guys get it together! Or I'll find a different internet provider.
There are a variety of reasons this may happen. Here are the first things you might try to correct that problem:
1. Quit the app. Double click the Home button to show the screen with running and recently used apps. Each app icon will have a sample page above it. Flick up on the page (not the app icon) and the page will fly away and the app icon will disappear. This quits that app. Then reset your iPhone. Press and hold both the Home button and the Sleep/Wake button continuously until the Apple logo appears. Then release the button and let the device restart. You will not lose data doing this. It's like a computer reboot.
2. If that didn't work quite the app again and then delete the app. I'm assuming that the problematic app is not one of the default apps that came on the iPhone. To delete an app tap and hold on the app until it begins to juggle and displays an X. Tap on the X and confirm that you want to delete the app. Then download the app again from the app store. Be sure you back up your data first. You will not be charged to download the app again so long as you are using the same Apple ID that you used to download it originally.
3. If those attempts still failed contact the developer of the app to determine if they are aware of the problem and whether they have a fix planned for it. -
Why does this script not work when run with osascript cli?
I wrote the following to interface with geektool to display a list of todo's on my desktop (i'm sure it's been done elsewhere, but I wanted to try it myself). I had it working fine until I tried ordering the output to place the highest priority items at the top of the list. The following code works properly during development in Script Editor, but when geektool launches the command using osascript ~/Library/Scripts/todos.scpt it only displays the initial "TODOS:" without displaying the rest of the info. Searching the Applescript Release notes, I found that some versions of Applescript 1.8 had issues with null characters when using the osascript cli, however, I'm running 1.10.7 so it shouldn't be an issue (and I'm not sure how to check for null characters in Applescript even if it were). Anybody have any ideas on what's going on here?
set output to {"TODOS:
set highpri to {}
set medium to {}
set low to {}
set nada to {}
tell application "iCal"
repeat with i in calendars
repeat with j in todos of i
if (completion date of j as string) is equal to "" then
if priority of j as string is equal to "high priority" then
copy summary of j & "
" to end of highpri
end if
if priority of j as string is equal to "medium priority" then
copy summary of j & "
" to end of medium
end if
if priority of j as string is equal to "low priority" then
copy summary of j & "
" to end of low
end if
if priority of j as string is equal to "no priority" then
copy summary of j & "
" to end of nada
end if
end if
end repeat
end repeat
end tell
return (output & highpri & medium & low & nada) as stringwell, i'd been pulling my hair out for quite a while with this and decided it was time to ask for help, but I thought I'd give it one last shot and found a resolution almost immediately. I figured that problem had to be caused by the way applescript was concatenating the lists, so I got rid of the lists completely and it still wouldn't work. This convinced me that it must be newline related since that was the only special character left in the string. I opened up the script in vi, but the default compiled script format is not human readable. The osascript man page indicated that it would accept both compiled and text scripts, so I gave it a try, and osascript handled the raw text file wonderfully.

Why does this video not support on my ipod?
Hey, i imported a video with handbrake and decided to put in the chapter markers. But this video when i added it to itunes and i plug my ipod in, it says that it isn't able to transfer it onto my ipod because my ipod doesn't support this kind of video. This video should work because the bitrate is 1500kbps and 160kbps for audio. The size is 720x384. And i have other videos that size on my ipod so i know this isn't the problem. But i just need to know why this is happenin.
The error $ is not defined means that the jQuery library isn't loading correctly. The page is loading the library from Google rather than from the site itself.
When you have a problem with one particular site, a good "first thing to try" is clearing your Firefox cache and deleting your saved cookies for the site.
(1) Bypass Firefox's Cache
Use Ctrl+Shift+r to reload the page fresh from the server.
Alternately, you also can clear Firefox's cache completely using:
orange Firefox button (or Tools menu) > Options > Advanced
On the Network mini-tab > Cached Web Content : "Clear Now"
If you have a large hard drive, this might take a few minutes.
(2) Remove your google.com cookies (save any pending work first). You can call up the cookie dialog anywhere on google.com using:
* right-click and choose View Page Info > Security > "View Cookies"
* Alt+t (open the classic Tools menu) > Page Info > Security > "View Cookies"
Or if you call it up from another site, change the site in the search box at the top of the dialog to google.com. Then you can remove your Google cookies individually.
Then try reloading the page. Does that help?
If jQuery still won't load, review your extensions for any designed to reduce cross-site interactions or targeting Google or privacy. You can review those here:
orange Firefox button (or Tools menu) > Add-ons > Extensions category -
Repaint() an applet from a swing applet, why does this code not work?
below are three files that work as planned except for the call to repaint(). This is envoked when a button is hit in one applet and it should repaint another applet. I opened them up in a html file that simply runs both applets. If you could see why the repaint doesn't work I'd love to know. good luck.

}I can fix your problems
1. You get an error here because you can only invoke the superclass's constructor in the subclass's constructor. It looks like that's what you're trying to do, but you're not doing it right. Constructors don't return any value (actually they do, but it's implied, so you don't need the void that you've got in your code)
2. I'm not sure, but I think your call to show might be wrong. Move the setsize and setvisible calls to outside of the constructor -
Chart timestamp accelerating - why does this VI not work?
In fighting with TDMS files, I decided to experiment with a different approach to get what I need - a stripchart with a long history, that I can pause and scroll back through to look for anomolies. Came up with a clever (I thought) approach to it... Not the most elegant, but it should work. In the attached VI, I have 2 charts simulating my data on the left, and 2 charts that will be my scrollable history on the right. I worked out how to apply a correct timestamp to the charts, and am basically just passing the history from the source chart to the history one - unless the "pause" button is on, which allows me to scroll back. All of the charts are set with a window of 300 points, and the VI cycles at 200ms, so it should be a 1 minute active window before it scrolls off the edge and into the buffer. The chart buffer size is set for 180000 for each chart, which should be 10 hours of data at this polling rate.
I start the program, everything is fine. Both sets of charts begin populating, the timestamp is chugging away in 1 second intervals, it looks beautiful. Then it all falls apart. Once the chart is full, and begins scrolling, the timestamp goes nuts and begins accelerating. It takes exactly 1 minute to fill the chart from empty, then the timestamp starts flying much faster - at least twice the speed, as the data being collected (and the actual time elapsed). I haven't been able to determine if it is a set multiplier in speed, or if it is ramping up faster and faster.
So... How is this possible? I can't see what the code could be doing to cause this. It's so very frustrating, because the pause and scroll feature works perfectly, just like I planned it. But without an accurate timestamp, this is completely useless.
Edit - oops, attached old version of VI, updated with correct one now.

Advanced Chart with Timestamp.vi 30 KBI didn't run the code, but it sounds like this - http://lavag.org/topic/16789-chart-scale-falling-out-of-sync-with-data-grid/ . You can check if he found a solution.
Personally, I tend to use XY graphs because they allow more control and don't require a single dx for all points. They are more of a pain because you have to buffer the data yourself, but the code for that is reasonably easy and I believe there's an XY chart example in the example finder.
Try to take over the world! -
String answer = new String("");
in = new BufferedReader(new InputStreamReader( connection.getInputStream ()));
String test = new String("");
for (int i = 0 ; i < 1000 ; i++)
answer = in.readLine();
if (answer == null)
System.out.println ("null");
break;
else
test += answer;
System.out.println ("answer: " + answer);
System.out.println ("test: " + test);
Many times, the loop will go through 2 iterations but each time, test is only equal to the first answer. The second, third, fourth etc.time it goes through the loop, it should concatenate the value of answer to the end of the string variable test. So why is it that whenever i run the program that has this code, the loop might lloop many times (let's say 2 time) but the value of test is only the first answer, and not the first answer concatenated with the second answer.It worked for me...my code looks like this...i used FileInputStream instead of connection..
import java.io.*;
class Forum {
public static void main(String a[]) throws IOException{
String answer = new String("");
BufferedReader in = new BufferedReader(new InputStreamReader( new FileInputStream("hi.txt")));
String test = new String("");
for (int i = 0 ; i < 1000 ; i++)
answer = in.readLine();
if (answer == null)
System.out.println ("null");
break;
else
test += answer;
System.out.println ("answer: " + answer);
System.out.println ("test: " + test);
my hi.txt is like this:
fasd rea reks krie
fsdfasd
asdfasd

The output is
answer: fasd rea reks krie

Is this not the way u want??? -
I have 4 statements.
echo off
plus80 / @z:\nesp1483_batch
plus80 / @z:\nesp1484a_batch
exit
The first statement plus80 / @z:\nesp1484_batch inserts records into a table and creates a report and deletes the table.
However the second statement plus80 / @z:\nesp1484a_batch is not working properly. I want it to insert records into a table, create a report and then delete the table but it is not working properly. It is hanging up on this statement.
I need to say plus80 to get the program to execute properly.
I have also tried sqlplus /@z:\nesp1484a_batch but this does not work either.
What do I need to do to make the third statement to execute properly?I know that it is not working
because the response time is slow and I have over 15 minutes
and nothing is happening. How do you know it is not working as opposed to just working slow?
Do you have any logging routines in your code? If you have, switch on them on and see what's happening. If not, now is a good time to think about including them...

Why does this MagicMouse not scroll pages?
I have a new iMac purchased today. It has the MagicMouse and for some reason that is not working properly.
When I swipe my finger over the mouse (up or down) the web page or application window does not scroll. I have to move the mouse over to the scroll bar, grab it and scroll that way.
Can someone tell me what might be wrong with this?Look in System Preferences > Universal Access > Mouse & Trackpad tab > Mouse options... button > Check scrolling.

Simple Question: Why does this code not exit properly?
This code is pretty simple. All I want to do is load and play a sound file in an application, but this code to load the sound file does not exit properly. I know that some resources must be allocated which I need to deallocate in order to shut down the process, but I don't know what to call to do a proper shut-down. Any help would be appreciated.

The only change I made was in the URL part - file: instead of file:/ .
The other was of course to play the soundclip ...... :- ) I got really confused the first time I played it .
