In order to enable or disable a control you need to write a U8 value to the Disabled property of the property node for that control.
The values are:
0 = Enabled
1 = Disabled
2 = Disabled and Grayed Out

Tree node images changes.. with start and stop button

I create the animator extends JPanel, which start and stop can be controlled with Swing Timer. It works fine with animation control over the panel.
Now, I have a tree with each image at each node.
when the start button clicks, one node image should be animated.
It is implementable. If animation.gif would have worked, I did't have to do this, but animation gif has fatal error with time interval.
any words would be appreciated. Thanks =

Damn !
With version 1.2.1 I think you'll have to create a new class that extends PositionPathInterpolator and add a pause() anr resume() method to it.
i suggest something like:
public class MyPositionPathInterpolator() extends PositionPathInterpolator {
// add some constructors if necessary
private float pauseAlphaValue = 0;
// override computeTransform method
public void computeTransform(float alphaValue, Transform3D transform) {
   float newAlphaValue = alphaValue + pauseAlphaValue; // calculate new alpha value
   if(newAlphaValue > 1) // modify it if it is out of bounds
      newAlphaValue -= 1;
   else if (newAlphaValue < 0)
      newAlphaValue += 1;
   super.computeTransform(newAlphaValue, transform); // computeTransform with the right alpha value
public void pause() {
   this.setEnable(false); // it won't compute transform anymore
   pauseAlphaValue = this.getAlpha().value(); // retrieve current alphavalue
public void resume() {
   pauseAlphaValue -= this.getAlpha().value();
   this.setEnable(true) // restart computing transform
}Now you invoke pause and resume methods on your myPositionPathInterpolator object when user clicks on the buttons.
Of course it is a trick and it will work only with increasing alpha.

I'm new with HTML and CSS, need help

I'm creating a static html webpage for an assignment. Someone suggested to me that I could manually create my webpage using dreamweaver instead of creating it from scratch, which has turned out much easier. However one of the tasks require me to Create a CSS stylesheet to work with my structural HTML. So my question is where is the CSS code inspector (if there is one). Is it possible for me to somehow add this and link it to my HTML?
Sorry if my question isn't clear, I'm quite new to this and have only a general idea of what I am doing.

Because the assignment requires me to submit the css and html separately. It means both have to be done is separate Notepad files (this is where I will paste the code from dreamweaker to submit).
I'll save the html as hompage.html and the CSS as homepage.css
So I don't know if I can use option 2.
My teacher wants to be able to open my css and amend it so that all her amendments actually work with my html.
So lets say this is my html that I copy from dreaweavers inspector:
<html>
<head>
<title>Search Engine Title Goes Here</title>
<link rel="stylesheet" type="text/css" href="hompage.css">
</head>
<body>
<div id="container"> </div>
<div id="header"> Header Goes Here</div>
<div id="sidebar"> Left Navigation Goes Here</div>
<div id="content"> <p>Content Goes Here</p></div>
<div id="footer"> Footer Goes Here </div>
</body>
</html>
How would I write my css, would it be like this? (assume this is my homepage.css file):
body {background: #ffffff; margin: 0; padding: 0;}
a {color: #2b2bf6;}
#container {width: 900px; margin: 0; padding: 0; background: #dddddd;}
#header {width: 900px; height: 150px; margin: 0; padding: 0; border: 0; background: #f346e1;}
#sidebar {width: 200px; height: 400px; margin: 0; padding: 0; border: 0; float: left; background: #f0e811;}
#content {width: 700px; height: 400px; margin: 0; padding: 0; border: 0; float: left; background: #8be0ef;}
#footer {width: 900px; height: 70px; margin: 0; padding: 0; border: 0; float: left; background: #000000; clear:both;}
I saw this example on the internet, would this work?

Starting and stopping video and MP3

I can't seem to get around my video and audio files starting when I arrive at the page. I'm even using some example code with start and stop buttons. This is in CS4 Flash. I expect it's because the ActionScript is in the wrong place because when I run the movie it flashes through all of the pages on the site without stopping at the home page. Is there some generic code that will allow me to simply swap out the name of the video or audio file I want to start. If there is, do I need to locate it on its own layer at the top of the timeline? Thanks to anyone who can help.

>>Why is it that the default setting for a video player placed on the stage
is to start playing when the page appears? I would think it would be
paused.<<
I don't know it doesn't seem any more logical to have it paused. I assume it
is just a preference on the part of the developers of Flash.
>>Is there some piece of script that can correct this situation<<
There are several ways to pause the video playback at teh beginning of the
Flash movie. It actually depends on how you have the movie inserted into the
time line. If you used an FLVPlayback component, then all you have to do is
click to select the component, open the component inspector
(window>component Inspector) and se the autoplay value for the component to
false. If you have the video inserted another way let me know.
>>Forgive my naivete but I am trying to learn the ways of Actionscript
wherever I can find it and builds something at the same time.<<
Thats always hard. What tecnology do you normally work with Ajax? C++
The comment about the behavior of video suggests you work with a technology
that has the opposite autoplay behavior.

Need help getting Tomcat 5.0.28 to start (and stop, eventually)

Hi!
I am such a newbie to the Terminal and writing scripts, so please forgive my naiveté. I have successfully installed Tomcat in my /usr/local directory, but I am having trouble creating files to start and stop Tomcat, per the instructions on the following page:
http://developer.apple.com/internet/java/tomcat1.html
I've followed the directions but continue to get the following error after I execute ~/bin/start_tomcat.
-bash: start_tomcat: command not found
My file contains the following code:
#!/bin/sh /n
export CATALINA_HOME=/usr/local/jakarta-tomcat-5.0.28 /n
export JAVA_HOME=/usr /n
$CATALINA_HOME/bin/startup.sh /n
If anyone can help me, I would really, really, really appreciate it!
Thanks!

Why are there all those "/n" there? Either you or the place you copied from has the wrong slash. But still, it's wronger than that to have them at all: "\n" means a newline (i.e., press "return") not the actual "backslash en" characters. Sometimes people post code with those \n visible: by making it explicit where a line-break should be, one doesn't have as much trouble when a web browser reformats the text and puts line breaks where they don't belong.

Starting and stopping timer using external inputs interfaced with labview

hello,
I have trouble finding how to start and stop the timer using external voltage or current pulse. we are interfacing a circuit to labview. so for that we need to count the time it takes between the two external voltages. We have to keep on comparing the voltages to some reference voltage. And when the external voltage crosses the reference voltage we have to start the timer and again we have to stop the timer using tha same logic. We need it for time calculation between the triggers.
hope you can help.

https://decibel.ni.com/content/docs/DOC-23334 is agood example to start. You need to modify it to include stop trigger.

I do not have the 'Advanced' tab on the menu bar. I am trying to change ringtone on my iphone 4s. Have done the following: Right cick on song, entered the start and stop times, but unable to proceed as need 'Advanced' tab in order to change to option.

You don't need to upgrade your software. But if you're struggling with Spry, IMO you should cut your losses and switch to something better for the longrun.
If you have a budget to work with, I highly recommend Project Seven's Pop-Menu Magic 3. It's easy to use in DW CS4, 5, 6 or CC. More importantly, it's bullet proof and works in all devices.

If you don't have a budget to work with, you can roll your own menus with jQuery plugins. A bit more effort on your part, but they perform better than Spry.

How to use counter as an start and stop trigger in 6009

Hi ALL.
I'm using USB 6009 as a subject of to acquire data.
I would like to know on how to use the counter digital input as a start and stop trigger.
The acquisition will only start when the first pulse of the digital signal is received and it will stop when the desired number of pulse is received.
I was trying to use the VI as attachment as my reference. However, after tried, the VI is not working for USB 6009 as the counter input cannot be used as a trigger.
I would be happy if anyone could suggest me some ideas on this matter.
Thanks.

DigitalStartandStopTrigger.vi ‏32 KB

Hi Kate.
Thanks for your response.
For your information, I've design my VI using the counter method. However, it doesnt work well. Please see the figure below. The file also attached with this reply.
At first, the first counter from Device 2 will start counting. If the counting equal 0, then the acquisition for Device 1/AIO also the counter of Device 1/ctr0 begin acquiring data and counting the edges respectively.
However, when I did the test, it doesn't work as wanted. It is happened because when counter of device 2 in not equal to 0, the acquisition for Device 1 not happened as it will go to false state.
Is there anything that someone could suggest on how to start the acquisition for device 1 only and if the counter of device 2 is equal to 1. I would like the acquisition of device 1 start only when the counter of device 2 is equal to 1. I cannot use the trigger as 6009 is not support for it.

Control DC Motor (start and stop) with LabView

I never used Lab View before. For a project, we have to use Lab View to make a small dc motor （HP:1/2， RPM 1725) start, and stop. I have no idea how to do this. Any advice/help anyone? Any tutorial or vi. would help!

Hi there,
Search for “H-bridge” for a common DC motor control circuit, the input terminals from the bridge can be controlled using any DAQ device with digital output lines from LabVIEW. For example: https://decibel.ni.com/content/docs/DOC-17062

When I try to install iTunes 10.5, it says, "There is a problem with this Windows Installer package. A program run as part of the setup did not finish as expected. Contact your support personnel or package vendor." I have Windows XP and I need help.

5, it says, "There is a problem with this Windows Installer package. A program run as part of the setup did not finish as expected. Contact your support personnel or package vendor." I have Windows XP and I need help.

After reading all these posts, one by one did not resolve my problem until I got the very end. Regardless of what step would resolve your problem, these are the steps I would recomment to everyone for a what seems to be a safe and fool-proof upgrade to iTunes 10.5.
1. Stand alone upgrade to the latest Quicktime version
2. Go to control panel and "change" then select repair to the following applications in the order specified by the post on Oct 27. (Notice I skipped Quicktime because it had been upgrade manually,and Bonjour did not have a "repair" option)
iTunes; Apple Software Update: Mobile Device Support; Apple Applications Support
Some of these applications may not appear if they do not apply to your configuration (no iPhone, or no iPad, or other apple devices).
Once all updated, I did not need to restart nor launch any applications, I simply went straight into the 10.5 upgrade, and where it normally got stuck, this time the installation continued for a while longer until it completed successfully.
Great work everyone who contributed! Thank you very much!

I want cRIO to start and stop acquisition with push of physical button on cRIO, is that possible?

When using my cRIO 9024 on the field, I prefer to be able to start and stop acquisition with push of a physical button on cRIO.
I mean I don't want it to be "as start-up," I don't want cRIO to start acquisition as soon as the power is supplied.
Is that possible?
Solved!

Hi Cashany,
you surely can read that switch status. But there are easier (but more expensive) ways to switch a button. Fiddling with a pen or small screwdriver to switch USER1 isn't what I call "user friendly"...
- You have atleast 2 voltage inputs on your module available. Use a switch to supply voltage to those inputs. Use a "real" button!
- You have a serial port available. You could set some pins to GND or voltage and check their status inside cRIO/RT target...
Best regards,

In XI R2 you can stop & start job servers by their types, but in XI 3.1 I don't think you can do that, b'cos it doesnt list by server type just shows jobserver for crystal, webi & deski.

Starting and stopping a loop

I am importing a list of 10,000 emails into memory and then
comparing them to a database which holds over 400,000 records. It
doesnt take long for the <cfquery> to time out. I know there
must be a way to loop thru 20 or so, then stop, then loop thru the
next 20, etc. I cannot lengthen the timeout so I need to figure out
a way to process the data in chunks. Thanks.

Are you sure you can not lengthen the timeout. The
<cfapplication ...>
tag allows one to define a specific timeout for a given page,
as long as
that is less then the maximum timeout defined in the
administrator.
If this is not sufficient for your needs you will need to
break up your
process over multiple requests. Just starting and stopping
the loop in
a singe request does nothing for reducing the timeout
threshold of the
page. You can do this with scheduled tasks, web services,
and|or the
<cflocation ...> tag. You will need to pass through
relevant data about
what iterations to process, and use some kind of extra
request storage
for the results, such as server|application|session scopes,
databases or
files.
Hope that gives you some help.
Ian
Sounds like more than I know how to do. I cant change the
timeout because its set that way on purpose. I think Ill leave this
alone for now. Thanks.

Music starts and stops during playback of burned DVD

I really need help with this problem...I made a slideshow and added music from itunes in the program IDVD. Once I burned the DVD the music will start and stop throughout the DVD and not at chapters as I read in other threads - but in random places on the DVD. The DVD sounds like it gets hung up and then starts again. This is my first project using IDVD, so any help would be great.

Debra,
Do your project have music purchased from iTunes? If so, that could be the cause of this problem. Music from iTunes is DRM-protected and can cause problems in playback. To take care of this, first burn all of your purchased music to a CD, then reimport in an aiff format. To do this, in iTunes, go to iTunes>Preferences>Advanced>Importing. Look for "Import using", and use the drop-down menu to select AIFF encoder.
Good luck.
