The solution to adding modules in Drupal is confusing (usually when many modules exist ). The status is as follows: 1. after you click the "warranty" button, the page cannot be properly displayed and a blank page appears. 2. refresh the page and issue that many items in the navigation are no longer available, you cannot click another item. The status is as follows:1. after clicking the "warranty" button, t

Python custom modules, packages, and python custom modules 1. Save a hello. py file in the F:/data/python directory. Hello. py >>> def hello(x): print x Directory Import >>> Import sys >>> sys. path. append ('f:/data/python') # Add a path, which is one-time >>> import hello >>> hello. hello (5) # Call 5 2. Import the custom module without changing sys. path: Method 1: place the hello2.py file i

Only one module (ng-app= "") can be in Angularjs, and one module may have multiple controllers (ng-controller= "")In their own experiment, JS and the page can be written in a piece, but large-scale project development, it is best to do HTML and JS separation, easy to maintain later.Shown: Ng-app can only have one, multiple controllers in one ng-app, and no meaning when defining multiple Ng-app.Run as follows:"-//W3C//DTD XHTML 1.0 transitional//en" "HTTP://WWW.W3.ORG/TR/XHTML1/DTD/XHTML1-TRANSIT

The previous article explains how to implement internationalization/multi-language in Silverlight. Here we will introduce how to implement multiple languages and use resources in modules/modules in prism. The implementation of multiple languages is the same: Add strings. resx, strings. en-US.resx, strings. zh-CN.resx and so on, then modify the first constructor to public, manually modify the project file,
