How do I make a program wait for a set amount of time?

Basically, I want there to be some amount of lag after a repaint, so how do I do that? I want it to wait a fifth of a second, basically. Is there a quick way to do this?
By the way, the program is not running on a timer, so I can't just have the timer stop.

didn't see that:
you need to use a thread
public class Something implements Runnable
Thread t;
public Something()
t = new Thread(this);
t.start();
public void run()
while(true)
//your stuff goes here
try
t.sleep(200);
} catch(InterruptedException exc) { ; }

How do I make my program wait for tasks to execute

I want to write a few java classes to do things for me, namely:
1) Create a directory on a local machine which is named to the current date - that I can do with Calendar and String
2) Download the latest committed code from SVN - I suppose I will have to use a process to call SVN from command line. Does Java have a local process caller? I'm familiar with Qt's QProcess, but I'd like to do this with Java.
3) email confirmation that the tasks have executed - I can use javax.mail for that.
If anyone has comments on 2, I'd like to know, please. My greatest concern is how to make sure that steps 1-3 execute sequentially. How do I get that right?

Continuing a loop for a set amount of time

Hi,
I'm am trying to alter a previously written program have run into a problem.
The program is set up so that when the input exceeds a set level an output voltage to a buzzer is created; the buzzer continues as long as there is an input. What I need it to do is to continue this output for a set amount of time.
I've been searching the forum and found this straight forward solution from adamsjr.
"The easiest way to do this is to use a two Tick Count functions. The first
one is outside of a While loop, the second one is inside of the While loop.
Wire the first one through a tunnel into the While loop, add on the appropriate
ms (5*1000), wire the sum to one input of a compare function. Wire the
other input of the compare function to the second Tick Count function. Exit
the loop when the compare shows the second Tick count value is greater than
the summed value."
I've got placed the output subVI into a while loop and followed the above directions and this doesn't seem to work. I'm wondering if I would also have to include the input subVI into the loop or is there another possible solution
Thanks ahead of time,
Kristen

Hi Kristen,
You have the compare function implemented incorrectly. You need to make sure that the first terminal of the "Greater than or equal" function connected to the output of the sum, and the second terminal to the tick count in the while loop. The first terminal corresponds to x parameter and the second terminal is for the y parameter. So if x is greater than or equal to y, then the loop will need to exit.
You can see how long a subVI is taking if you put a flat sequence structure within your subVI around the entire subVI code. The first frame would only have a tick count going into an indicator, the middle frame your normal code, and then the final frame would contain another tick count wired into another indicator. Then you can subtract the second indicator value from the first and get hold long it took to execute the middle (core) of your code for that subVI.
I highly suggest using the highlight execution and probes and other debugging techniques such as breakpoints to diagnose where the data is being held up.

How to generate a continuous sine wave for a given amount of time

I am trying to output a continuous sine wave for a speaker, but I am having difficulty making it continuous rather than looping the signal for a given amount of time, which causes discontinuities. There is a VI in the Labview examples titles Continous Generation, but it produces a square wave. Is there a way to adapt this VI such that the amplitude and frequency can be used as inputs to create a sine wave?

I found a VI that ships with labview(7.0)called continuous sound output. the output of this is a sine wave or you can change it to whatever you want.
Sorry cannot help more

How do I make a movie wait for a FLV cuepoint

I'm trying to synch a "talking head" FLV with some graphics,
so I simply want to get my movie to wait for a cuepoint to begin
playing again. I'm making it Flash 7 compatible, so I'm using the
older Media Display component.
Is there a "stop" and "wait for cuepoint" that would work? If
someone could give me the actionscript I should paste in the frame,
it would be greatly appreciated, since I don't really know
actionscript that well. Thanks.

I'm sensing that you don't know much actionscript. If you
want to do much that is really fun and cool you will need to learn
some.
Start with the help files. Everytime you use a new component
or class go to the Actionscript Language Reference or the Component
Dictionary. Don't try searching it will generally only confuse you
more.
This next bit is going to sound silly, but the differences
are subtle and please take it in the manner it is offered.
When you say you'd like to pause at a certain frame you mean
a movieclip that you have, right?
If you check all the information about the FLVs and the Media
component you will find there is absolutely nothing that allows it
to make a movieclip pause or play. But if you check the MovieClip
class you will find there are the MovieClip.stop() and the
MovieClip.play() methods. These are the only ways to get a
movieclip to pause/stop and or play. There are no others.
So you have most of the answer there in your second post. It
is just worded a bit off.
You need a movie to pause (for which you will use the
MovieClip.stop() method) and when a cuepoint happens you will need
to start the movie using MovieClip.play();
If you check the MediaDisplay component directory there will
be sample code for how to listen for a cuepoint. I'm still using
Flash 7 so my help files are organized a bit differently, but what
you are looking for is under Media.cuePoint.
Notice the code at the bottom of the entry – READ the
whole entry, even if you don't understand it all now, read it,
outloud if it helps. You will need to have an instance of the
playback component on the stage (in this example it is called
myPlayback, but you could call it whatever you wanted, just make
sure that both names are the same.
I recommend trying this outside of your current project. Set
up a simple new document, put an instance of the playback component
on the stage, give it an instance name, assign an FLV to it, give
it a cuepoint or two, and then add the listener code, just as it
is. See how it works? Do you get the trace statements?
Then you can develop it a little further. Add some named
movieclip to your stage. Add a line myClip.stop(); Also notice that
you can give your cuepoints names? Put a few in and call some start
and some stop (or whatever you want.) Then instead of a trace in
the cuepoint listener have something that says, "If the cuepoint is
called start I should tell the movieclip to play and if the
cuepoint is called stop I should tell the movieclip to stop/pause."
I could easily write all this code out for you, but what
would be the fun of that for you? Give it your best shot and post
back as you accomplish things.

Setting up a Log File monitor to inactivity for a set amount of time

I have set up a number of log file monitors to alert when certain conditions apply, such as the word "ERROR" or "exception". Now I have a request to set up an alert if the log file has not changed for 20 minutes. I have been
searching and have not found any information on how or if this can be done. Anyone???
I am running Operations Manager 2012 SP1
The log files are simple text files.

Hi!
You could create a timer reset monitor that reads the log file every 19 minutes for a wildcard pattern (everything matches) and configure the successful search to healthy. Further, you've to configure the timer reset to 20 minutes and configure the
timer reset state to unhealthy (warning/critical).
Keep in mind that SCOM reads from the last line from the previous run every time. If your file rotates (based on a schedule or size) SCOM will not read the lines until the latest line is reached. For more information refer to

Make a program wait

Hi, I am new to Java, hence the forum, I was hoping someone could help, I was hoping to find a method or a way to make a program wait for the return key to be pressed, similar to the getch() function in C++ I have messed around a little with System.in.read() but I get an exception and I have no idea how to handle exceptions, any help would be greatly appreciated.
Thanks in advance.

you can simply do this by waiting in a while loop
you have to import java.io.*;
insert this into the main
boolean goon = true;
String answer = "";
while(goon)
//your code for number generation
System.out.println("Result of"+num1+" + "+num2+" ?");
BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
try{
answer = in.readLine();
catch(Exception e){
System.out.println("Error: "+e.toString());
//the string answer contains the input from the console
//if you want to compare it to an integer do this
int numnber = 0;
try{
number = Interger.parseInt(answer);
catch(Exception e){
System.out.println("Error: "+e.toString());
//code to compare the answer to the result

Extract code into methods, so that when an action is performed a method is called. That way you can reuse the method for purposes such as resetting textfields to their default values, scores to default values, etc.
You can go one step further and seperate the GUI layer from the processing layer, by deriving classes that for example maintain and calculate a score.

Best way to make program wait for input from NI USB 9162?

Hi, I'm somewhat new to Labview, but through all the tutorials and online help I'm still having trouble getting this to function properly.
The USB adapter is hooked up to a network cable split into single wires reading in a voltage coming through several seperate oscillators.
Testing in the lab, the program included below works fine when I run the program, then quickly administer a shock to the table. In the real world scenario though, I'm trying to make the program wait to record data until the first shock reaches the first oscillator before recording data, but I just can't seem to find an easy way to make this work.
Attatched is an example of the program. Any help would be greatly appreciated. Thank you.

Acq&Graph Voltage-Int Clk-rh-tt-1.vi ‏56 KB

Hi,
I think I have the answer you're looking for! Please see the attached VI.
I moved the graph indicator inside the "true" case of the case structure. Before, your VI was sending data to the graph from an empty timestamp constant with each iteration of the "false" case. Now the VI only sends data to the graph if a true is read.
If you're wondering why it takes a bit of time for your graph to stop updating before it stops writing new data, it's because you're filling up a buffer of sampled data by using a queue. If you're writing to the buffer faster than you're reading from the buffer, you may encounter an "overflow" situation when the queue gets full. To avoid this, you might consider using a notifier rather than a queue. It's the exact same thing as a queue, but it gives you only the most recent value, allowing new values to overwrite old values.
Hope this helps.

How do i make the program hold after it has created a JFrame

I have created a JFrame with which the user shall login to a server. I call this JFrame from my main method (the JFrame-class is in a separate file). My problem is that after the login-window is created and set visible, my main method continues, i would like it to wait until the user have logged in before running the rest of the code.
this i my main method:
new LoginWindow();
System.out.println("Logged in: "+Session.isLoggedin()+
                "\nUsername: "+Session.getUsername());Session.isLoggedin() returns a boolean, true if user is logged in and otherwise false. class LoginWindow extends JFrame.
i have tried to use a while-loop to solve my problem:
while(!Session.isLoggedin()) { }and also
whiel(true){
    if(Session.isLoggedin())
        break;
}these while-loops never breaks, i have waited for about 3 min after successful login.It isn't because Session.isLoggedin() returns false, it does return true after a successful login (i've checked).
the funny thing however is if i print something in the while-loop i does break when login is finished
example:
whiel(true){
    System.out.println(Session.isLoggedin());
    if(Session.isLoggedin())
        break;
}this code makes the program wait until the login-phase is complete but i don't want it to print "text" a few thousand times while the user is logging in. (i've used "hej" as output aswell)
Since i have no idea how long it will take for a user to log in i can't use the System.sleep(value) method.
I would really appreciate any help
Thanks in advance

I am still curious about why the while-loop only breaks if i print something using System.out.println(""), i didn't think that would make a difference since the break-statement remains the same.In general you should avoid trying to use while (true) or its variants in a Swing GUI as it often messes with the EDT, the main thread that renders the GUI graphics and interacts with the user.
My problem i however partially solved by using a JDialog instead of a JFrame. I am planning on using JFrame later in the program so the problem might come back to haunt me if it isn't solved.This may not be a great idea. Usually an application has one single JFrame. Most other distinct windows a dialogs of one sort or another and should be JDialogs, not JFrames. Often better still is to use a CardLayout to swap JPanels or other components.

How can I make a bootable disk for Mountain Lion?

How can I make a bootable disk for Mountain Lion?

Make Your Own Mountain/Lion Installer
1. After downloading Mountain/Lion you must first save the Install Mac OS X Mountain/Lion application. After Mountain/Lion downloads DO NOT click on the Install button. Go to your Applications folder and make a copy of the Mountain/Lion installer. Move the copy into your Downloads folder. Now you can click on the Install button. You must do this because the installer deletes itself automatically when it finishes installing.
2. Get a USB flash drive that is at least 8 GBs. Prep this flash drive as follows:
Open Disk Utility in your Utilities folder.
After DU loads select your flash drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
Click on the Erase button. The format process can take up to an hour depending upon the flash drive size.
3. Locate the saved Mountain/Lion installer in your Downloads folder. CTRL- or RIGHT-click on the installer and select Show Package Contents from the contextual menu. Double-click on the Contents folder to open it. Double-click on the SharedSupport folder. In this folder you will see a disc image named InstallESD.dmg.
4. Plug in your freshly prepared USB flash drive. You are going to clone the content of the InstallESD.dmg disc image to the flash drive as follows:
Double-click on the InstallESD.dmg file to mount it on your Desktop.
Open Disk Utility.
Select the USB flash drive from the left side list.
Click on the Restore tab in the DU main window.
Select the USB flash drive volume from the left side list and drag it to the Destination entry field.
Drag the mounted disc icon from the Desktop into the Source entry field.
Double-check you got it right, then click on the Restore button.
When the clone is completed you have a fully bootable installer that you can use without having to re-download Mountain/Lion.
Note: The term Mountain/Lion used above means Lion or Mountain Lion.

How can I make a "property node" for a VI?

Hello!
If I add a boolean button on the FP then I am able to make a property node for that button in the Block Diagram. But how can I make a property node for a VI? I have several VI:s an that together is one program. What I need to do is to verify what kind of VI some of my VI:s is. I need to verify if it is .exe or .vi-file, and if it is .exe then I want to disable run, abort, run continuously bottons otherwise not. I have hard that this is possible to do programmaticaly but I can´t figure out how. I am aware that I could do that manually in the File->vi properties->customize->windows appearance but theese choises makes it last forever.
I want to be able to stop and run and everything if it is a .vi file, but if it is .exe-file then all those buttons should be disabled.
Anyone have an example on this?
In an other message at this Forum I read "You can use the `Front Panel Window. Allow Runtime PopUp`" property to disable run-time shortcuts menues programmaticaly, but still I dont know how to create this property node.
/Amir

You really shouldn't open a new thread. If you don't understand something, ask and we will explain it.
Like I said in the other thread, you can check if you are running in LV or an EXE by using the Application>>Kind property. To get it, place a property node (from the Application Control palette) on the diagram, click it and find the property.
To set the properties for the VI, place another property node, right click it and select Select Class>>VI Server>>VI. You should have the properties you want under Front Panel Window.
To learn more about LabVIEW, I suggest you try searching this site and google for LabVIEW tutorials. Here and here are a couple you can start with. You can also contact your local NI office and join one of their courses.
In addition, I suggest you read the LabVIEW style guide and the LabVIEW user manual (Help>>Search the LabVIEW Bookshelf). I believe chapter 17 of the user manual explains about programmatic control of VIs.
