Consider using static methods to hold a Create function instead of revealing object constructors: type HashTable<'k,'v> with static member Create : IHashProvider<'k> -> HashTable<'k,'v> Recommendation: Avoid revealing concrete data representations such as records. Where possible, avoid revealing concrete representations such as records, fields, and implementation inheritance hierarchies in framework APIs. The rationale for this is that one of the overriding aims of library design is to avoid revealing concrete representations of objects. For example, the concrete representation of System. DateTime values is not revealed by the external, public API of the .NET library design. At runtime the Common Language Runtime knows the committed implementation that will be used throughout execution. However, compiled code does not itself pick up dependencies on the concrete representation. Recommendation: Use active patterns to hide the implementations of discriminated unions. Where possible, avoid using large discriminated unions in framework APIs, especially if you expect there is a chance that the representation of information in the discriminated union will undergo revision and change. For frameworks, you should typically hide the type altogether or use active patterns to reveal the ability to pattern match over language constructs. We described active patterns in 9. This does not apply to the use of discriminated unions internal to an assembly or to an application. Likewise, it doesn t apply if the only likely future change is the addition of further cases and you are willing to require that client code be revised for these cases. Finally, active patterns can incur a performance overhead, and this should be measured and tested, though their benefits will frequently outweigh this cost. add watermark to pdf using itextsharp c# Add Water mark image to PDF using iTextsharp, C# and VB.Net in ASP ...

This gives us some degree of safety, although still not as much as we would get under Java. A rogue object might implement getArea() to return a string rather than a numerical value, for example. We have no way of knowing the return type of a JavaScript function unless we call it, because JavaScript functions have no predefined type. (Indeed, we could write a function that returns a number during the week and a string on weekends.) Writing a set of simple test functions to check return types is easy enough; for example: function isNum(arg){ return parseFloat(arg)!=NaN; } free birt barcode plugin, free code 39 barcode font for word, police word ean 128, birt ean 13, birt ean 128, print barcode in word 2007 c# add watermark to existing pdf file using itextsharp Create watermark text in pdf using itextsharp | The ASP.NET Forums

In this example, you could create individual tables for the following: Property addresses Years that houses were built on the properties (eg, if a house is rebuilt on a property due to remodeling or disaster) Property owners Property assessed values Property parcel numbers Step 3: Begin adding data records to individual data tables The property addresses data table could be presented with the records shown in Table 2-1.. Note The rationale for this is that using large, volatile discriminated unions freely in APIs will encourage NaN is short for not a number, a special JavaScript variable for handling number format errors. This function will actually return true for strings if they begin with a numeric portion, in fact. parseFloat() and its cousin parseInt() will try their best to extract a recognizable number where they can. parseFloat("64 hectares") will evaluate to 64, not NaN. We could firm up our addAreas() function a little further: people to use pattern matching against these discriminated union values. This is appropriate for unions that do not change. However, if you reveal discriminated unions indiscriminately, you may find it very hard to version your library without breaking user code. add watermark to pdf using itextsharp c# Using iTextSharp To Watermark /Write Text To Existing PDF's ...

If s1 returns a value of 32 and s2 a value of 64 hectares, then addAreas() will return 96. If I didn t use parseFloat, I d get a misleading value of 3264 hectares! In summary, duck typing keeps things simple but requires you to trust your development team to keep track of all the details. Duck typing is popular among the Ruby community, who are generally a very smart bunch. As one moves from a single author or small tightly bound team to larger projects involving separate Recommendation: Use object interface types instead of tuples or records of functions. In 5 you saw various ways to represent a dictionary of operations explicitly, such as using tuples of functions or records of functions. In general, we recommend you use object interface types for this purpose, because the syntax associated with implementing them is generally more convenient. Recommendation: Understand when currying is useful in functional programming APIs. Currying is the name used when functions take arguments in the iterated form, that is, when the functions can be partially applied. For example, the following function is curried: let f x y z = x + y + z 88812 88812 add image watermark to pdf c# c# itextsharp PDF creation with watermark on each page - Stack ...
