Now that you have a system for adding and editing tags, you need a way of associating tags with pages. As was mentioned earlier, you can choose to do this in two ways. The first is with the pagetag controller to provide an interface to allow users to manually add entries to the pagetag table to create the associations. If the tag table contained more fields or didn t have a column that could be used naturally as a primary key, then this would be a good option. In this case, though, the tag name provides a unique way to specify the tag, so you can simply provide a list of all available tags on each page with a check box next to each, and users can simply select the boxes of the tags they want to use. Figure 14-5 shows what a page will look like when you ve finished this section and saved the tags associated with a page. pdf417 java decoder Read PDF417 in Java - pqScan.com

The application is split into two major parts: the user interface class and the database interface class. The user interface uses the database interface to access the classes from the QtSql module. The user interface is contained in the ImageDialog class, and the database interface is found in the ImageCollection class. By splitting the code that uses SQL into a specific class, you avoid having SQL strings throughout the source code. There are several reasons to split the code containing SQL from the rest of the code. First of all, that part of the code can be tested in detail, which is important since any syntax errors in the SQL statements are detected first at run-time. It is convenient to convert between the types used in the database and Qt s classes in one place. And when you change database engines, it might be necessary to review and update some of the SQL statements used. word document als qr code, winforms qr code reader, crystal report barcode ean 13, how to connect barcode scanner to visual basic 2010, .net data matrix reader, winforms ean 13 reader pdf417 java api PDF417 SVG JavaScript Barcode Generator 17.01 Free download
