I wants to run more than one instance of my Adobe Air Application, So to do this it needs to be change the ID in "application.xml" file of the application which is present in the folder META-INF of installation directory.
But i don't know how to change this ID at run-time.
Does anyone have an idea how to do this or any other process is there to solve this problem ?
You can't change ID at run-time. The only way to run several instances is to prepare several packages with different appID in app descriptor xml - so to have several app descriptors.
I am using TeamCity as build server and have a little trouble when configuring projects and their dependencies.
Eventually I want to get the checkout directory of project dependencies to configure certain build steps. For that I have the variable %teamcity.build.checkoutDir% for the checkout directory of the project itself.
However, I did not find something like %dep.<dependencyID>.teamcity.build.checkoutDir%.
Is there a way to get the checkout directory of a dependency?
You can add a parameter (say checkoutDir ) in the first build whose value is equal to %teamcity.build.checkoutDir% . You can then fetch this value in the dependent build (either through snapshot or artefact dependency)
I am using this myself and I can access my dependent Build's Checkout directory with...
%dep.<dependecyID>.teamcity.build.default.checkoutDir%
I believe this will only work with a Snapshot Dependency though
I have a windows phone application in which two listpicker and one listbox in a form.
When i press a window start button or close the application and again start the application it does not retain the previous filter value can anybody give a solution .
Thanks
Try using the Application Settings of Isolated Storage where you could store and retrieve the values.
Check out this sample:
Store and Retrieve Application Settings Using Isolated Storage
Or else you could preserve the state of the page:
How to preserve and restore page state for Windows Phone 8
In your App.xaml.cs file are two methods: Application_Activate and Application_Deactivate. In the deactivate function you have to store the current filter in the isolated storage, in your activate you have to load them.
In your page.xaml.cs you have to use the loaded informations in the OnNavigatedTo function.
Is there a way to get the app config settings from inside my Trigger.io app without having to repeat the values in the parameters module? Specifically, I'm looking to grab the version number.
I've had success (today) with using forge.config.version
Example:
alert(forge.config.version)
This returned the value I had entered into the app's configuration.
It used to be available under forge.config in Javascript, but isn't anymore. For a while it wasn't available under this key (around v. 1.2). It has since reappeared.
I am trying to write a script that will parse a local file and upload its contents to a MySQL database. Right now, I am thinking that a batch script that runs a Perl script would work, but am not sure if this is the best method of accomplishing this.
In addition, I would like this script to run immediately when the data file is added to a certain directory. Is this possible in Windows?
Thoughts? Feedback? I'm fairly new to Perl and Windows batch scripts, so any guidance would be appreciated.
You can use Win32::ChangeNotify. Your script will be notified when a file is added to the target directory.
Checking a folder for newly created files can be implemented using the WMI functionality. Namely, you can create a Perl script that subscribes to the __InstanceCreationEvent WMI event that traces the creation of the CIM_DirectoryContainsFile class instances. Once that kind of event is fired, you know a new file has been added to the folder and can process it as you need.
These articles provide more information on the subject and contain VBScript code samples (hope it won't be hard for you to convert them to Perl):
How Can I Automatically Run a Script Any Time a File is Added to a Folder?
WMI and File System Monitoring
The function you want is ReadDirectoryChangesW. A quick search for a perl wrapper yields this Win32::ReadDirectoryChanges module.
Your script would look something like this:
use Win32::ReadDirectoryChanges;
$rdc = new Win32::ReadDirectoryChanges(path => $path,
subtree => 1,
filter => $filter);
while(1) {
#results = $rdc->read_changes;
while (scalar #results) {
my ($action, $filename) = splice(#results, 0, 2);
... run script ...
}
}
You can easily achieve this in Perl using File::ChangeNotify. This module is to be found on CPAN: http://search.cpan.org/dist/File-ChangeNotify/lib/File/ChangeNotify.pm
You can run the code as a daemon or as a service, make it watch one or more directories and then automatically execute some code (or start up a script) if some condition matches.
Best of all, it's cross-platform, so should you want to switch to a Linux machine or a Mac, it would still work.
It wouldn't be too hard to put together a small C# application that uses the FileSystemWatcher class to detect files being added to a folder and then spawn the required script. It would certainly use less CPU / system resources / hard disk bandwidth than polling the folder at regular intervals.
You need to consider what is a sufficient heuristic for determining "modified".
In increasing order of cost and accuracy:
file size (file content can still be changed as long as size is maintained)
file timestamp (If you aren't running ntpd time is not monotonic)
file sha1sum (bulletproof but expensive)
I would run ntpd, and then loop over the timestamps, and then compare the checksum if the timestamp changes. This can cover a lot of ground in little time.
These methods are not appropriate for a computer security application, they are for file management on a sane system.
