Slightly less common than asking for a file name is asking for a directory, but the QFileDialog class has a static member for this as well. Listing 3-14 shows the getExistingDirectory method being used. The arguments are the same as for the methods for opening and saving files, except that no filter is given because there is no point to filtering for extensions when working with directories. Listing 3-14. Asking the user for a directory QString dirname = QFileDialog::getExistingDirectory( this, tr("Select a Directory"), QDir::currentPath() ); ... The resulting dialog, when used on the Windows platform, is shown in Figure 3-25.

To understand exactly what is going on when you create a web page, it is useful to be able to see the HTTP information being sent back and forth between a web browser and a Pylons application. One good tool for doing this is the LiveHTTPHeaders extension for the Firefox web browser, which you can download from http://livehttpheaders.mozdev.org/. Once you have installed it, you can select View Sidebar LiveHTTPHeaders from the menu to load the extension in the sidebar, and it will display all the HTTP information sent and received on each request. You often have to tell the user something important, or ask for a word or a number, which is where message boxes and input dialogs come in handy. Using them saves you from having to design and implement your own dialogs. Instead, you can use Qt s premade dialogs through static methods just like asking for file names. qr code java app Tested: Java midlet QR code readers - James Royal-Lawson

Reading & Scanning QR Code Barcodes in Java class. here is the sample code : String[] datas = BarcodeReader.read(new File("C:/ QRCode - Barcode -Image.gif"), BarcodeReader. QRCode ); Pass your QR Code barcode image file, and barcode type to BarcodeReader, and it will return all QR Code barcode data in the image file. The root cause of the vulnerability is that escaping was only applied to the new_password variable and not the uname variable. Quite likely, the programmer assumed that the former is an external input and hence must be escaped or validated, while the latter is safe because it was retrieved from the session (and ultimately from the database), which he might have considered a trusted source of data. As this example demonstrates, such corner-cutting can be extremely dangerous. As such, we recommend treating all parameters that are inserted into a query as potentially dangerous, and accordingly escaping or sanitizing them, no matter what their origin is. For example, the query that updates a user s password should be written as follows: new_passwd = request.getParameter("new_passwd"); uname = session.getUsername(); sql = "UPDATE USERS SET passwd='"+ escape(new_passwd) + "' WHERE uname='" + escape(uname) + "'"; You can download the Firefox web browser from http://mozilla.com/products/firefox. It will run on Tip the Windows, Mac OS X, Linux, and BSD platforms. It is particularly useful for web development because of the extensions available that give you fuller access to the processes going on within the web browser. Another particularly useful extension is the Web Developer toolbar available from https://addons.mozilla. org/en-US/firefox/addon/60, which offers facilities for managing cookies and style sheets as well as for outlining block-level elements and tables. Firefox also has powerful extensions such as Firebug, which in addition to its JavaScript and DOM manipulation facilities allows you to analyze page load times. I will discuss Firebug in 15 when I cover Ajax. The QMessageBox class is used to show messages to the users (it can also be used to ask basic questions such as Do you want to save the file ). Let s start by having a look at the three different types of messages that can be shown. Figure 3-26 shows three dialogs with messages of different importance. When you request a page, the browser sends an HTTP request to the server. When the server receives that request, it will calculate an HTTP response. Depending on the request, it may retrieve information from a database or read a file from the filesystem to prepare the response. HTTP supports different types of requests. You are probably already familiar with the GET method used to retrieve information from a URL and the POST method used primarily to send form data, but there are other less well-known methods such as HEAD, OPTIONS, PUT, DELETE, TRACE, and CONNECT. Figure 3-2 shows a simple HTTP GET request where you can see the HTTP information sent when visiting http://127.0.0.1:5000/. java qr code reader Java QR Code Generator - zxing example - JournalDev
