Using the goto command does not stop the current execution
for example if I have
gotoAndStop(2);
trace("1");
The application will still perform trace command and then move to frame 2. I would like to know if there is any such command that immediately ceases the execution of any code left in the frame?
You can use the
return;
instruction to break the execution of the frame script.

I use Node JS & Puppeteer to perform an automated task, my script works well but from a hundred loops, the script stops, or encounters an error
I would like to restart the loop in this case, thank you
pause should stop the execution until something happens. But in my case where i have OCTAVE 5.1.0 on OS WINDOWS 10 is not doing its work properly. It does ignore all pause statements in script and execute the whole file.
I am running this program in my installed octave application in command window with GUI.
What may be the problem?
I have tried pause with function brackets
pause();and without function brackets pause; but still problem remains same.
%do something
plotData(X, y);
fprintf('Press enter to continue.');
pause;
%do something
plotData(X, y);
I except that script will first plot data and will stop execution till key is pressed to enable me to analyze data then after key press it would plot another plot with processed data.
But it just plot both plots in fast manner that i could not see it.
There are few bugs related to pause that have been introduced since version 5.1 and seem that recently have been fixed. It will be available in the next version. You can try alternative functions like kbhit or switch to a previous version.
I have the following code saved as script.
% demonstration of hold
clf;
t = linspace (0, 2*pi, 100);
plot (t, sin (t));
hold on;
plot (t, cos (t));
title ({"hold on", "2 plots shown on same graph"});
hold off;
When I execute the script within Octave, Octave's viewer shows the figure.
However, when I execute the script from the command line (Ubuntu) the viewer opens and closes alone very quickly without showing any figure.
I don't know if this issue has to do with Octave or Ubuntu. I apologize if the question is very naive.
When running and Octave script from the command line, Octave is launched to execute it, and when the script ends, Octave terminates too. This is why you see the figure windows created and immediately destroyed. There no longer is a program running to show these figure windows.
If you add a pause statement at the end of your script, Octave will wait at that statement until you press a key, then continue. So after you press the key, the script ends and Octave terminates. But while it is waiting, the figure windows will be visible.
You can use waitfor to prevent Octave from termination until the figure is closed. First you should get graphic handle of the figure. Some functions including clf , plot ,... can return a graphic handle. Then use waitfor with the handle as its argument.
h = plot(1:10);
waitfor(h);
or
h = clf;
plot(1:10);
waitfor(h);
I am relatively new to SSIS. I have two script tasks. If either task fails, the error handling logic is the same. The second script task must always execute regardless if the first script task has failed.
I have created the above as shown in the image link below. However, It seems the error handler task is only executed once. So if both script tasks terminate in error, the error handler is not executed for the second script task (presumably because it was already executed after the first script task.
Is there anyway to achieve this or do I simply have to duplicate the Error Handler task for both script tasks.
see SSIS Image below
You would need to duplicate the task to have it execute twice.
One way to have this event fire twice while only defining it once is to set up an event handler.
To do this, navigate to the 'Event Handlers' tab.
You'll see there is a dropdown on the right, where you can select the event handler type. Here you'd probably want either OnTaskFailed or OnError. OnTaskFailed fires once per failed task, whereas OnError fires for every error that occurs within a task.
On the left, you can select the executable, which allows you to define a scope for the event handler. If you scope this to the package, you'll have event handlers executed for every task in the package. If there are more tasks in your package than the two Script Tasks you've shown in your post, and you only want it fired for those two, you could put them into a Sequence Container (in the Control Flow), and then scope the event handler to that Sequence Container.
You then just click the text in the middle of the pane to create a handler, and add the necessary tasks there (it works in a similar way to the Control Flow).
The event handler will now execute for both tasks.
It's also worth mentioning that within these handlers are lots of useful system variables you can use, e.g., System::ErrorDescription in OnError.
What I've described will look something like this:
I have set up a ScheduledTaskAgent with a LaunchForTest (which I know is being called). When I launch the main app, it seems to successfully add the task and OnInvoke runs to completion (calls NotifyComplete), but never seems to run again. I've pared down the OnInvoke to do nothing other than call NotifyComplete, but it still only ever runs the one time following ScheduledActionService.Add and ScheduledActionService.LaunchForTest (with a few seconds' delay).
What could be preventing it from running more than once?
I am assuming it is about PeriodicTask.
You are right. It will run only once and that is because of the LaunchForTest call, wherein you have specified the timespan. After that execution, you have to wait another 30 minutes for it to run.
Are you adding the ScheduledActionService.Add in App.xaml.cs? I mean, on the launch event? You should. If you have that, then you could run the app again, and it will invoke the task agent.
If you are hitting the breakpoint even once that means that you are correctly set up. You have to remember that ScheduledActionService.LaunchForTest is just a function that you can call under debugger. It will not work when the app is released.
Basically, there is no way to fire the background agent, you can register it and then forget it. Windows Phone OS will invoke it periodically.
If you want to debug the periodic task multiple times then you can put LaunchForTest in a loop with delay.
