In the preceding script, the application logic is the code that connects to the database server and retrieves the rows from the news table. The presentation logic is the HTML code that outputs the articles. The problem with a script like this is that it can be hard to maintain, especially if you change the way the news system works (for instance, if you wanted to rename the table to news_articles). While it appears that you only need to change the code in place, consider what would happen if you wanted to display your news articles on other pages also. You would need to duplicate this code and then maintain it accordingly. Now consider using the MVC pattern to implement this code. There are essentially two key changes that would be made. The first would be to move the code that retrieves articles from the database into a reusable component (either a PHP class or function). We would then call this new function to retrieve the articles so they could be output using HTML. In MVC terms, this new class or function is the model. The second change would be to separate the call to retrieve the articles from the actual HTML. While this change isn t quite as important as the first change, it is still important as it allows you to change your HTML code without having to worry about how the data used in the HTML is generated. In MVC terms, this is separating the controller from the view. Figure 2-2 shows how the previous code would be structured to use MVC. c# download pdf from url: Reading Files From Given Specific URL Using WebClient - C# Corner selectpdf c# Extract Tables from PDFs - CodeProject

The R.java source file will be updated when we rebuild this project to include a reference to our layout file (stored as main.xml in our project s res/layout directory). The other difference is that we need to get our hands on our Button instance, for which we use the findViewById() call. Since we identified our button as @+id/button, we can reference the button s identifier as R.id.button. Now, with the Button instance in hand, we can set the callback and set the label as needed. The results look the same as with the original Now demo, as shown in Figure 4 1. open pdf and draw c#: Windows C# How to add, modify and delete the annotation in PDF file c# pdf parse table PDF SDK Technology | C# .NET Toolkit | LEADTOOLS

Aug 11, 2013 · Text version of the video http://csharp-video-tutorials.blogspot.com/2013/08/how-to-upload-and ...Duration: 24:16 Posted: Aug 11, 2013 Most of the examples in this book use Active Record as a database access library. Active Record is a simple way to access databases and database tables in Ruby. It is a powerful object-relational mapping (ORM) library that lets you easily model databases using an object-oriented interface. Besides being a stand-alone ORM package for Ruby, Active Record will also be familiar to web application developers as the model part of the webapplication framework Ruby on Rails (see http://ar.rubyonrails.org/). Active Record has a number of advantages over traditional ORM packages. Like the rest of the Rails stack, it emphasizes configuration by convention. This means that Active Record assumes that your tables and fields follow certain conventions unless you explicitly tell it otherwise. For example, it assumes that all tables have an artificial primary key named id (if you have a different primary key, you can override it, of course). It also assumes that the name of each table is a pluralized version of the model (that is, class) name; so if you have a model named Item, it assumes that your database table will be named items. how to upload and download pdf files from folder in asp.net using c# iText® 5 .NET, a .NET PDF library download | SourceForge.net

SharpPDF is a C# library that implements different objects for the creation of PDF documents with few steps. It is created for .NET framework 1.1 and it can create ... Figure 2-2. The news article example represented in MVC In the MVC version, you would effectively have three files. The model: < php function get_articles() { mysql_connect(...); $result = mysql_query('select * from news order by article_date desc'); $articles = array(); while ($row = mysql_fetch_objects($result)) { $articles[] = $row; } return $articles; } > Every GUI toolkit has some basic widgets: fields, labels, buttons, and so on. Android s toolkit is no different in scope, and the basic widgets will provide a good introduction to how widgets work in Android activities. And the view: <html> <body> <h1>News Articles</h1> < php foreach ($articles as $row) { > <h2>< php echo $row->headline ></h2> <p> < php echo $row->body > </p> < php } > </body> </html> While this example is fairly trivial, considering how the news articles are maintained (that is, inserted, edited, or deleted) will highlight the advantages of MVC. It is a nightmare to maintain code that mixes SQL insert statements directly within the HTML output for the corresponding page. First, the script in Listing 2-3 connects to the database and sets up the models, as you ve seen in previous examples. Essentially, the remainder of the script runs two SQL statements and prints out the results in a nice format. The first SQL statement returns the overall results for all games combined. To retrieve that result, the query groups by the drink field, and then uses a correlated subquery to retrieve the total number of wins: c# pdf library github How to convert PDF Byte Array into PDF document? - Laserfiche Answers
