We ve taken you through some of the stranger and more interesting features of the JavaScript language in this appendix, with two purposes in mind. The first was to show the expressive power of the language. The second was to point out several traps for the unwary, in which thinking in an OO style may result in suboptimal or even dangerous code. We ve looked at JavaScript s support for objects and at the similarities between the Object and Array classes. We ve seen several ways of instantiating JavaScript objects, using JSON, constructor functions, and the prototype concept. Along the way, we ve discussed how to tackle OO concepts such as inheritance and interfaces in JavaScript, in ways that work with rather than against the language. In our exploration of JavaScript Function objects, we saw how functions can exist independently of any object to which they are assigned and even be borrowed or swapped between objects. We used this knowledge to get a better understanding of the JavaScript event model. Finally, we looked at closures and saw how some common programming idioms can create closures unintentionally, potentially resulting in memory leaks. Compared to Java or C#, JavaScript offers a great deal of flexibility and scope for developing personal styles and approaches to the language. This can be liberating for the individual programmer, provided that you know what you are doing. It can also present problems when working in teams, but these problems can be alleviated by shared coding conventions or house styles. JavaScript can be a very enjoyable language to work with, once you understand what makes it tick. If you re coming to Ajax from a structured OO background, we hope that this chapter has helped you to cross the gap. add watermark to pdf c# Add Text Watermark and Image Watermark to PDF in C# .NET ...

Using this library, you can add watermark to PDF file in C# and VB. Sequences are frequently used to represent the process of streaming data from an external source, such as from a database query or from a computer s file system. For example, the following recursive function constructs a seq<string> that represents the process of recursively reading the names of all the files under a given path. The return types of Directory. GetFiles and Directory.GetDirectories are string[], and as noted earlier, this type is always compatible with seq<string>. open System.IO let rec allFiles dir = Seq.append (dir |> Directory.GetFiles) (dir |> Directory.GetDirectories |> Seq.map allFiles |> Seq.concat) This gives the following type: <html> <head> <script type='text/javascript'> var req=null; var console=null; var READY_STATE_UNINITIALIZED=0; var READY_STATE_LOADING=1; var READY_STATE_LOADED=2; Here is an example of the function being used on one of our machines: add image watermark to pdf c# Display watermark image in PDF using iTextsharp in ASP.Net, C# and ...
