Systemd and starting another program after OpenVPN finishes connecting

I have a program that I want to launch only when OpenVPN has established a connection. The problem is it is instead starting too soon, and going out into the Internet first before later using the OpenVPN connection. I am having it start after OpenVPN with the following two lines in the .service file:
Requires=[email protected]
After=[email protected]
Is there a proper way to have it instead start after OpenVPN finishes its connection? Right now I manually can start it after systemctl status [email protected]
reports:
Initialization Sequence Completed
But that manually method is very much suboptimal. I also want to have this other program start at boot which would completely preclude the manual method.

What if you use Requisite=[email protected]? As I understand it, that will ensure that the service is active and running before allowing the next to start...
Additionally, if you want to be able to start the unit manually, without the openvpn.service started (that is by using "systemctl start <whatever>"), then you could use RequisiteOverridable=[email protected]
Edit: I guess there is also the additional question of whether the unit reports a success after starting the binary or actually making a connection. I have never used openvpn, so I don't know about this. But take, for example, the network.target and the network management services. With the exception of NetworkManager.service (more specifically the NetworkManager-wait-online.service), the service is reported as successful, and the network.target is reached when the daemon itself is started, not when a full connection has been established. If it reports success before full connection, that will make this much harder.

Opening and manipulating another program from an application or script

Hello all,
I'm trying to create a prototype of a portable input device for a computer. The idea is that the input device allows the same input as a normal wireless pen tablet, but augmented with special features, which could (for example) open programs and switch between them.
Now our current idea is to use a second monitor to run our mockup interface on. So basically an application of some sort that has a rectangular part to serve as the pen input area and some buttons alongside it for the extra functionality.
Now for the questions: is it possible to open and interact with programs on the mac through another application? Would Applescript or a Cocoa application be able to this?

Hi Spacy, and welcome to the Dev Forums!

Yes.
Would Applescript or a Cocoa application be able to this?
Both.
However, opening another app and interacting with it are two different topics. In general, you'll always be able to open another app. But except for privileged programs such as debuggers, you can't expect to do much else with another app unless it wants you to. In other words, if you programmed the other app, you'll be able to control and interact with it anyway you want from either Applescript or a Cocoa app. But if the app doesn't support Apple Events or any other kind of interprocess communication (IPC), you may not be able to do much except open and close it.
Here are some links that might be useful to you:

Can't start any program after upgrading to Mavericks from Mountain Lion.

After upgrading my Macbook Pro from Mountain Lion to Mavericks, I can't start any program from the dock or finder. The screen flashes briefly gray, then returns to the desktop. I repairded permissions from the recovery partition.

No need to repair permissions from the recovery partition. You can do that using the Disk Utility app located in HD > Applications > Utilities.
As for the issues with your Mac. Check to see if the startup disk needs reparing. (not the same as permissions)
The startup disk may need repairing ...
Launch Disk Utility located in HD > Applications > Utillities
Select the startup disk on the left then select the First Aid tab.
Click: Verify Disk (not Verify Disk Permissions)
If DU reports errors, restart your Mac while holding down the Command + R keys. From there you should be able to acces the built in utilities in OS X Recovery
Make sure to back up all important files first before using OS X Recovery.

Threads - Multithreaded app. - How to cancel one and start another?

I've searched through the forums for some direction on this but have been unsuccessful in finding anything I could use yet.
What I am trying to accomplish is the following:
1. I have a multithreaded application
2. User can enter login information and then initiate the login thread by clicking the login button
3. Login button turns into a Cancel button during login attempt
4. If user changes their mind, they can initiate the cancel login thread by clicking the cancel button
How can I stop the login thread and start the cancel thread? Reading through the API (1.3.1), it seems that necessary methods have been depreciated. Could anyone offer me any insight/examples?
Thanks,
KJ

Have a boolean variable in the login thread which is checked at various points through the process and set to true when login starts. When the user clicks cancel, set it to false, then the login thread will end itself next time it checks the boolean.

My iPhone 5 says it is connected to iTunes and starts syncing when it isn't connected

Everytime I open my itunes it says that my iphone is conncted and starts to tell me it is syncing the content, how can I fix this? thanks

Hello Probes13,
It sounds like Wifi syncing may be enabled in iTunes. The article iOS: Syncing with iTunes found here http://support.apple.com/kb/ht1386 outlines how to enable Wifi syncing but rather than checking the box that enables it, you would uncheck it.
Wi-Fi syncing
Open iTunes
To set up Wi-Fi syncing, connect your iOS device to your computer with the included USB cable. Select your device under Devices on the left-hand side.
In the Summary tab, select "Sync with this [device] over Wi-Fi".
Whenever the computer and the iOS device are on the same network, the iOS device will appear in iTunes, and you can sync it. The iOS device will sync automatically when all of the following are true:
The iOS device is plugged in to power
iTunes is open on the computer
The iOS device and the computer are on the same Wi-Fi network
While the iOS device appears in the left-hand column of iTunes, you can select the content tabs and configure sync options.
Click Apply or Sync to sync the iOS device.
If the iOS device does not appear in the Devices section or you are unable to sync, please see this article for troubleshooting.

Sterling

How do I reset and start another game.

Hello
Please can someone help, I have spent several days on this and still can't get it to work.
The code below is ok, I am playing a bowling game using the keyboard and timer with a text readout of the elapsed time, the bowl moves a set number of pixels on the screen. whilst in full screen mode I would like to click a start/play button on the screen to start the game and timer again, everything is in frame 1. Also I would like the game to just accept the keycode 77 and keyboard event (2 events only to move the bowl) and then wait for the start/play button click.
Thanks
Mick

Hello, Thanks for the reply.
I put the code onto frame 20 and added the gotoAndPlay (1), the code played, I then clicked the button which reset the playhead to frame 1 , however the code didn't play a second time ?
Any idea why ?
Thanks for your help.

Stopping audio and starting another audio when button clicked

Hello,
I have a multiple slide document, and I want sound to stop
when they click the "Next" button, and another audio clip to start.
Here is what I have so far:
//audio
x = new Sound();
x.attachSound("Slide1");
x.start(0, 0);
musicplay = true;
forward_btn.onRelease = function() {
gotoAndStop("2");
numbering eq numbering++;
So I just want it to play audio clip "Slide2" when they click
forward_btn, and I want "Slide1" to stop.
Thanks!

Attach your second sound file to the frame that will play the
second sound. Then try adding stopAllSounds() before the
gotoAndStop("2"); to get the first sound to stop playing and then
play the second sound.

I am going to upgrade from leopard to snow leopard ( I just purchased the snow leopard disk today). Will I be able to keep my data and third party programs after installation?

Hi Apple Community,
This is my first time using the Apple Support Communities. After installing/upgrading to snow leopard from disk will I lose my data and my third party programs like Adobe Indesign?
Thank you in advance,
John

John... welcome to ASC,
You could if you don't backup everything to an external drive first. Always backup your important data before upgrading from one Mac OS to the next.
"Backup" most important word in computing
Make sure your Mac meets Snow Leopard's minimum requirements before upgrading > Mac OS X v10.6 Snow Leopard - Technical Specifications

Cancelling one SwingWorker and starting another

Hi,
I have a SwingWorker that does something in the background. When the user presses a button, I want the old worker to get canceled and I want to start a new one. The old worker should do some clean up/logging and close.
This is the code in my main dispatcher thread:
public void keyTyped(KeyEvent e)
     if(_controlThread != null)
          _controlThread.cancel(true);
                java.util.logging.Logger.getLogger("something").fine("output_here");
     _controlThread = new SwingWorker(...);
     _controlThread.execute();
}The Swing Worker has
if(this.isCancelled())
    Logger.getLogger("something").fine("closing");
    return;
}The problem is that the new Worker never starts. Also I noticed that
Logger.getLogger("something").fine("output_here");
never logs, I wonder why that is.
Anyone know what is going on here?
Thanks

               catch(ExecutionException ex)
                    System.out.println("Exception in ControlThread: done");
}This code will fail with a CancellationException in done(). I never saw this exception because I was using loggers and didn't look at the console output. The solution is to catch the CancellationException in done(). The problem is that it is not-documented that get() can throw a CancellationException, because then eclipse would require me to catch it.
