Execute a program for specified amount of time

Hi, I was wondering if anyone knows if it is possible to have a program run for a maximum time and, if it hasnt terminated on its own, stop it?
I've read about java.util.Timer and java.util.TimerTask but they seem to be for scheduling not counting and ending?
Can anyone give any suggestions please :)
Chris

when you execute an external program (with Runtime's exec method) a Process object is returned. This Process object has a destroy method that kills the external program... so yes, you can create a new class that extends TimerTask and overload the run method to call that Process's destroy method.

How to run the program for specified time

Dear Friends,
I have a small problem, I want to run my labview program for specified amount of time, Say for example it might be 1 hour or 5 hours or 10 minutes or even milliseconds(The time will be specified by the user).
How to write programs for this
And I want to get the system time in an instance, how it can be achieved,
Could you please help me?
Regards,
Rathan

Hi,
Herewith my screenshot attached. There are thre inputs thres, tempX, xValue, it is in side the while loop.'xValue' will be acquired every iteration, It will be saved through shift register and acquired to 'tempX' for the next iteration, 'thres' is a constant value. I'm doing some logic, and calculating the dvalue and convert it to a string and concatenate it with end of line character, then after writing it into a file.
In the logic, inside of the functional logic I'm assigning some values dValue, if the logic is true or else dvalue will be 0
What I require is I don't want to write the dValue in to a file, if it is equal to zero. Could you please help me, how to tackle this problem?
Thanks.

How to execute a frame of a flat sequence structure for a specified amount of time?

Hello,
I have a timed loop measuring a resistance value every 2 seconds. I would like to have this timed loop execute for a specified amount of time (e.g. 5 minutes). The timed loop itself is placed within a flat sequence structure so I am concerned that the measurement will be taken once and the next frame will begin to execute, without waiting 2 seconds for a successive reading (and not looping for, say, 5 minutes).
In other words, is it possible to have a frame of a flat sequence structure execute for a specified amount of time before moving onto the next frame?
Thanks for your assistance!
JFK_Aero
Solved!
Go to Solution.

All code in one sequence frame must complete before the next frame can execute. So as long as your timed loop is setup correctly, the next frame cannot run until your 5 minutes is up (N = 5 minutes/2 seconds/measurement = 150 measurements).
There are only two ways to tell somebody thanks: Kudos and Marked Solutions

How do I insert a pdf file (image) into a project as a picture-in-picture clip that will run for a specified amount of time?

I want to insert a pdf created from a ppt slide into a FCP X project that will run as a PIP for a specified amount of time. I was successful in bringing the image into the project as a clip but the default for the image is one second. When I try to change duration of the clip, I am able to enter a new time length but the actual clip doesn't change.

You select the PDF image in the timeline. You use Control-D and enter the new duration. What happens?

Writing a file for prescribed amount of time in a while loop after the triggering condition is met

Hello Guys,
I am trying to program an application in which if the trigger condition is met it should start to write the file.
I was able to do that, but if I want it to be written for certain amount of time, and once the trigger condition is met, it should continue to write the files for prescribed amount of time. I was not able to do this. The file name should also be updated accordingly.
I tried to with some options by keeping the creation of the file outside of the loop, if I do that then if the trigger condition is not met it will stop writing and I dont want that, as once the trigger condition is met it should be true thereafter.
So I cant keep any thing outside the while loop, bcaz then it checks the condition of the shift register for the trigger and I have it as a false constant.
I am attaching my application which is kind of mess and I have written in the application where I am having problems. For every iteration of while loop it makes a new file, and i dont want that, I want to write specific amount of time data to the each file.
Please take a look at my code and help me in solving the problem. Any insights and examples on how to do this thing will be a relief to me.
Thanks in advance.
Regards,
Nitin

what i am saying is to keep track of how much data you have written and whenever you need to make a new file you make 1.
here is a vi that i just made that should show you. let me know if you need any help understanding it.

Playing jpeg pictures for different amount of time

hello everyone.
i'm new to jmf and i have been reading a bit about it. so i tried the sample code at: http://java.sun.com/javase/technologies/desktop/media/jmf/2.1.1/solutions/JpegImagesToMovie.java (THIS WAS VERY HELPFUL)
this program displays each image for 1 second each.
now my problem is, i want to display these pictures for different amount of time... for example: display pic1 for 1 second, then display pic2 for 3 sec and so on.
can anyone help me please. THANKS

i'm new to jmf ..>The [JMF forum|http://forums.sun.com/forum.jspa?forumID=28] is the best place to ask JMF related questions, but I am guessing you are also new to Java, and to programming, so this forum might be best for the moment.

java JpegImagesToMovie -w 400 -h 300 -f 1
-o the.mov pic1.jpg pic2.jpg pic3.jpg..you might instead try..
java JpegImagesToMovie -w 400 -h 300 -f 1
-o the.mov pic1.jpg pic2.jpg pic2.jpg pic2.jpg pic3.jpg
Lines broken for clarity. Instead have command all in one line.
This simply repeats the second frame, three times. The .MOV format might 'optimize away' the second and third frame from the final file, but I would not count on it.
Of course, a far better way to animate images (with transition effects, full control over time, and all the bells and whistles) is to load the images into memory and create the slide show using the Java 2D abilities, mostly found in the Graphics class.

Wait for undefined amount of time

Hello All,
I have a requirement, where in I would want my activity in the workflow to wait for an indefinite amount of time. Then when a certain activity occurs, I would like to complete the 'waiting' activity.
So lets say I have the following process with 2 activities(A and B)
----------> A ----------> B(wait for undefined amount of time)------------->End
B needs to wait for some time, which I do not know.
Then when another event( PL/SQL activity) occurs, I need the event to trigger of the waiting activity B, to completion.
How can I acheive this?
Thanks in advance.
PHK

Luiz,
Lets say I have the following:
-------->A---------->B(needs to wait)-----No------>D----> END
\ Yes
C-------------->END
B is the activity which needs to wait. It has a PL/SQL function assciated with it.Lets say I have a result type of YES/NO associated with activity B. As soon as the workflow engine encounters activity B, it will execute the function associated with it. Lets the function ends with a result_out => YES, then immediatly C will be executed.
So setting a result type will not help. I need to wait at step 'B'
Regards,
PHK.

Is there a way to create a custom screensaver with pics/slides that display for different amounts of time?

Is there a way to create a custom screensaver with pics/slides that display for different amounts of time? Or even add a "video slide" into the screensaver?
My business has 3 TVs displayed in our lobby, each with its own apple TV and they are all linked to the same photo stream. Currently the Atv screensaver displays the photostream pictures of our products for the default 3 seconds. We just added pics/slides that now display messages and useful info for our customers but I want that info to be displayed for a longer period of time than the pictures to give people a chance to read it.
I tried using flickr and powerpoint as a work around but no luck. I created a slide in powerpoint with play length of 15 secs and saved it as a wmv file. I added that file to a "screensaver" set in flickr and pointed the Atv screensaver to that flickr set. It still displays everything, pics and the wmv file at the default 3 sec.
I know I can increase the duration of all pics in the screensaver to display for longer but the goal is to have the pics display at 3 secs and the info slides to display at 15 secs.

Welcome to the Apple Community.
No that's not possible.
If you have any suggestions that you think might enhance the Apple TV you can send Apple your feedback here

How to execute a loop for a user specified amount of time

This seems like it should be a no brainer. But I can't figure it out. What's the best way to execute a loop for a user specified number of seconds?

You can use the Elapsed Time Express VI (available in LabVIEW 7.0 and later). I have attached a sample VI saved in LabVIEW 7.1 format that shows how to use this Express VI.
Good luck,

When to Execute ABST2 program for Fixed Assets?

Hi,
Do we need to execute ABST2 program extractly at the end of the year 31/12/2008 or we can also execute after 31/12/2008?Because for my client-they have executed that program in July-2009.Now it is showing 0.01 differance for one of the depreciation account.the differance amount is showing for 2009 year.I am confused whether it is for 2008 or 2009.
Now in ABST2 program it is showing the 0.01 differance for 2009.Still can i ignore ABST2 error and can i proceed to close 2008 year for fixed assets? or it will give any error?
Kindlyl help me
Thanks
Suvarna

HI,
Generally it is executed before year-end closing. It picks up the asset balances and matches with the GL A/c balances. If any differences are found it shows the differences.
Run it and check in which year the difference popped up. Then verify balances for that particular year. If it started in 2008 you can check only 2008 balances and need not check for 2009.
Thanks,

Perform each task for certain amount of time

Hey,
The program I'm trying to create is a very linear one and involves performing three different processes after one another, each for a set amount of time.
I originally tried using case statements and timers to do this, but everything got very messy very quickly. I then looked at sequence structures however have read some bad things about them.
Could anyone point me in the best direction to achive this?
Thanks,
Sam.

Sam_R, Yamaeda is right. Sometimes things are so simple that you do not need a state machine. But sometimes you end up adding features to your simple little program and it ends up growing out of control. Trust me
There are a million examples of state machines out there. This makes a million and one. It does not address the part of your question about performing an action for a certain amount of time. I wanted to keep it as simple as possible while also demonstrating programmatically determining the next state and error handling.
I don't mean to sound condescending with this basic example. But I know there was a time when it seemed like advanced stuff to me. Hopefully someone will find this useful.

Display for variable amount of time?

Any thoughts on how I might accomplish the following:
I need to be able to display a graphic (or video) for a variable amount of time in captivate. This will be for a quiz type slide. The user will only have a limited amount of time to view a graphic, and then must answer a question. The graphic will only be displayed for fractions of a second ie. 1/16 to a half second. The user must be able to adjust the time, so that they can go from slow transitions to faster transitions (for training purposes).
My initial thoughts were:
Is there a me
1) Collect and set a variable in Captivate for the time to wait (user selects at run time), pass that variables value to a flash object and play the content for the specified length of time on the Captivate slide.
or
2) Create a new question type widget and define the widget parameters (time to display, image file to use, etc..), but will I be able to change a parameter at run time to allow the user to define the length of time to display???
or
3) Create the whole quiz in Flash, then tackle transmiting the quiz score/interactions back to captivate? I don't have eLearning suite, so I dont have the question extras as well.
I would prefer to do as much in captivate for speed and I am most familiar with it. I would prefer to do as little in Flash as possible since I don't know it as well.
Suggestions???

Sorry I lost part of the post:
Is there a method in Captivate to wait a period of time, and if so just set a conditional loop to show an object, wait the time, and then hide? I am figuring that there is not, so my three other plans of attack...

Program for transferring amount from one GL to another based on due date.

Hi
There is one requirement to show customers in differnt way (i.e. dues less than 6months seperately and more than 6 months seperately).
I have created one GL (customers due less than 6 months)
Now all balances are in one GL account i.e. customer due more than 6 monhts)
So is there any program which will transfer all the amount for due less than six months from one GL to other GL.
I also need such program for items (like prepaid accounts) which are entered directly into GL accounts.

Hi,
Yes there is one functionality available that is Reclassification or sorting of Receivables and payables. The tcode is FAGLF101 - Sorting/Reclassification (New), for this you need to do some configuration settings. The navigation path is New gl- periodic processing-Reclassify-Transfer and sort receivables & payables.

ITunes movies - 'freeze' for same amount of time I can play??..

I have a frequent problem with iTunes movies - when I download one from the Store it stops all the time. I can usually restart it by pressing pause and then play, although sometimes I have to go out of the movie altogether then restart and fast forward to where i was. It is incredibly irritating as you can imagine. Any ideas? The amount of time I get to watch the movie seems to relate to the amount of time I have before it of waiting. Eg if it stops and I restart instantly I only get a minute or so of movie, whereas if I stop the movie and only restart it after five minutes then I seem to get at least five minutes before it stops again.
So grateful for any help..

Writing binary file for fixed amount of time

Hello, I'm trying to write a binary file of multiple channels for a fixed amount of time before I perform my analysis. Does anyone know the best way to accomplish this?

Here is an example of one way to do what I think you are trying to do. There may be a more elegant way of doing it, but this is pretty simple and straight-forward. It basically writes a 5-integer array for 5 seconds and then stops. Let me know if you have any questions.
