However, this is not so. The <form> tag has the attribute enctype, which specifies how the browser should encode the form s fields when posting the form (see the HTML 4.01 Specification, Section 17.13.4, for more information) (Raggett, Le Hors, and Jacobs 1999). The enctype attribute specifies the encoding in the form of a MIME media type, also referred to as a content type (Freed and Borenstein 1996).12 The default encoding described previously corresponds to the MIME content type application/x-www-form-urlencoded. A commonly used alternative encoding is multipart/form-data, in which the form data is encoded as a MIME data stream, and which can be more space efficient for large quantities of non-text data for instance, file uploads (Freed and Borenstein 1996). What is not commonly known is that at least some browsers (such as Firefox, as of version 1.5) also support the text/plain encoding, which formats the form data as &-separated key/value pairs, just as application/x-www-form-urlencoded, but does not apply any encoding to the values themselves. For example, the form <form method="POST" action="http://www.mywwwservice.com/action" enctype="text/plain"> <input name='{"junk": "ig' value='nore", "new_password": "evilhax0r"}'> </form> results in a POST request whose body is formatted as {"junk": "ig=nore", "new_password": "evilhax0r"} That is, such a form can indeed be used to make a POST request with essentially arbitrary contents (in particular, well-formed JSON or XML), and can most likely be used to make an XSRF attack request that will be processed as valid by our application (the only constraint is that the request will contain a = character somewhere; there is usually a valid request that satisfies this constraint). As such, we must employ an explicit measure such as the use of action tokens to prevent XSRF against our server-side Ajax handlers. qr code java app download Android Barcode Reader and Qr Code Scanner using Google ...

I don't know what qualifies as best but zxing has a qr code generator for java , is actively developed, and is liberally licensed. .arg( event->x() ) .arg( event->y() ) .arg( event->delta() ).arg( event->orientation()==Qt::Horizontal "Horizontal":"Vertical" ) ); } There are more event handlers implemented in the EventWidget class. You can learn a lot about widgets by trying out different things on the widget and then studying the log. Although some of the messages you will want to internationalize will appear in controllers, most of them are likely to be found in your project s templates. Luckily, the internationalization and localization tools work in templates too. Let s change the multiple() action to use a template instead. Update it to look like this: def multiple(self): return render('/hello.html') Then create hello.html in your project s template directory with this content: <%! from pylons.i18n.translation import set_lang, get_lang %> <html> <head> <title>Multiple Translations</title> </head> free barcode generator source code in c#.net, java upc-a, vb.net qr code reader, c# data matrix reader, qr code generator c#, crystal reports data matrix java qr code generator maven Java QR Code Generator - zxing example - JournalDev

Creating an event filter is easier than inheriting a widget class and overriding an event handling class An event filter is a class inheriting QObject that implements the eventFilter(QObject*, QEvent*) method The method makes it possible to intercept events before they reach their destinations The events can then be filtered (let through or stopped) Event filters can be used to implement many special functions, such as mouse gestures and recognizing key sequences They can be used to enhance widgets or to change a widget s behavior without having to subclass the widget Let s try an event filter that removes any numerical key presses from the event queue The class declaration and implementation is shown in Listing 6-16 The interesting part is the eventFilter method, which has two arguments: a pointer to the destination QObject (dest) and a pointer to the QEvent object (event). qr code scanner java app download Write a QR Code Reader in Java using Zxing | CalliCoder
