startup

I need my code run at Django application startup, before Django starts listening for incoming connections. Running my code upon the first HTTP request is not good enough. When I use Gunicorn, my code must run in the parent process, before it forks. https://stackoverflow.com/a/2781488/97248 doesn't seem to work in Django 1.4.2: it doesn't run the Middleware's __init__ method until the first request is received. Ditto for adding code to urls.py . A quick Google search didn't reveal anything useful. I have just run into this problem myself, and the solution was to basically chain the commands to

There is a interface DispatcherListener in Struts2. The docs says "A interface to tag those that want to execute code on the init and destroy of a Dispatcher ." But how to use this interface. If I create a class that implements this interface, how should I configure it to Struts2? When a Dispatcher is instantiated, it could send to the listener notification when it's initialized or destroyed. The reference and code samples are from here . The simple usage is to instantiate a bean by the container via bean tag and add themselves in the init method and remove themselves when destroyed like it

I have an R-based GUI that allows some non-technical users access to a stats model. As it stands, the users have to first load R and then type loadGui() at the command line. While this isn't overly challenging, I don't like having to make non-technical people type anything at a command line. I had the idea of writing a .bat file (users are all running Windows, though multi-platform solutions also appreciated) that starts R GUI, then autoruns that command. My first problem is opening RGui from the command line. While I can provide an explicit path, such as "%ProgramW6432%\R\R-2.15.1\bin\i386

I want to run my program with the icon showing in the system tray but without the mainform showing from the start. Edit: lMainForm := new MainForm; lMainForm.ShowInTaskbar := true; Application.Run(lMainForm); Didn't work. As soon as Application.Run is executed, mainform is displayed along with the icon in the system tray. The problem you have at the moment is that you are calling the Application.Run overload that takes the main form as a parameter. This will show the main form which you do not want. Instead you should call one of the other Application.Run overloads. For example you can call

This question already has an answer here: How to tell whether a Mac Cocoa application has been launched normally or as a login item? 6 answers Cocoa app can add themselves to LSSharedFileList 's list of login items. This will allow application to be started when user logs in. However, is there a way to tell whether user started the application or the app auto-started at login? This is useful because in one case we can show a user interface in another we can hide the UI and run the app in background as a menubar app. Here's some code for this. I'm not sure what it returns for login items, but

i'm trying to install mongoDB in my system. As instructed in http://www.mongodb.org/display/DOCS/PHP+Language+Center , I downloaded php_mongo.dll and put it in ../php5.3.0/ext folder. Then I added extension=php_mongo.dll to php.ini. When I restarted WAMP, I got the following errors: PHP Startup: unable to load dynamic library php5.3.0/ext/php_gd2.dll and the same error for php_mbstring.dll,php_mysql.dll,php_mysqli.dll,php_pdo_mysql.dll,php_pdo_sqlite.dll. After that, I got another error: PHP Startup: Mongo: Unable to initialize module Module compiled with build ID=API20090626, TS, VC9 PHP

This question already has answers here : Passing options to Python executable in non-interactive mode (4 answers) Closed 4 years ago . I would like to execute a script work.py in Python, after executing some initialization script init.py . If I were looking for an interactive session, executing python -i init.py or setting PYTHONSTARTUP=/path/to/init.py would do the trick, but I am looking to execute another script. Since this is a generic case which occurs often ( init.py sets environment and so is the same all of the time), I would highly prefer not referencing init.py from work.py . How
