PDF page counter - Stack Overflow
I would recommend the iText pdf library. http://www.itextpdf.com/ It's a ... library imported; the java code to get the number of pages from a pdf is:

// ERROR: 'ComparisonHandler' cannot // inherit from special class 'SystemDelegate' public class ComparisonHandler: SystemDelegate { // }

[Serializable] class Document { public string Title; public string Data; }

In its place, C# uses the delegate keyword This keyword causes the compiler to generate a class similar to the one shown in Listing 124 Listing 125 shows the syntax for declaring a delegate data type

public delegate bool ComparisonHandler ( int first, int second);

Again it is important to point out that each of the messages shown above is associated with program code which is executed when the message is sent to the receiver object 223 A print spooler The final example that I will discuss is a print spooler This is a piece of system software that forms part of a multi-user operating system During the operation of such an operating system computer users will ask for files to be printed The computer normally has limited printing resources and so the print requests are queued up for each printer in the system, with the print spooler controlling the addition of print requests to the queues and the selection of those print requests that are to be satisfied A snapshot of a print spooler is shown in Figure 23 This shows a number of objects The first is a table which lists all the printers in the system together with their upper and lower print limits For example, one entry in the table states that printer TH44 will only be available to print files between 5000 to 10 000 lines of text; obviously the technology used in this printer is best for

Count number of pages in a PDF file by Frank Kusluski - Planet ...
Sep 22, 2017 · Count number of pages in a PDF file ... other object library, it uses only Visual Basic code by opening the PDF file in binary mode with the Open ...

class DelegateSample { public delegate bool ComparisonHandler ( int first, int second); }

"A cacophony of ramblings from my potpourri of notes"; Document documentAfter; using (stream = FileOpen( documentBeforeTitle + "bin", FileModeCreate)) { BinaryFormatter formatter = new BinaryFormatter(); formatterSerialize( stream, documentBefore); }

In this case, the data type would be DelegateSampleComparisonHandler because it is defined as a nested type within DelegateSample

Add an additional field to the serializable class [Serializable] class Document { public string Title; public string Author; public string Data; }

Instantiating a Delegate In this final step of implementing the BubbleSort() method with a delegate, you will learn how to call the method and pass a delegate instance specifically, an instance of type ComparisonHandler To instantiate a delegate, you need a method that corresponds to the signature of the delegate type itself In the case of ComparisonHandler, that method takes two integers and returns a bool The name of the method is not significant Listing 127 shows the code for a greater-than method

public delegate bool ComparisonHandler ( int first, int second);

class DelegateSample {

Surprisingly, even though all you did was to add a new field, deserializing the original file throws a SystemRuntimeSerializationSerializationException This is because the formatter looks for data corresponding to the new field within the stream Failure to locate such data throws an exception To avoid this, the 20 framework includes a SystemRuntimeSerializationOptionalFieldAttribute When you require backward compatibility, you must decorate serialized fieldseven private oneswith OptionalFieldAttribute (unless, of course, a latter version begins to require it) Unfortunately, SystemRuntimeSerializationOptionalFieldAttribute is not supported in the earlier framework version Instead, it is necessary to implement ISerializable , just as you did for encryption, saving and retrieving only the fields that are available Assuming the addition of the Author field, for example, the implementation shown in Listing 1426 is required for backward-compatibility support prior to the 20 framework:

public static void BubbleSort( int[] items, ComparisonHandler comparisonMethod) { // } public static bool GreaterThan(int first, int second) { return first > second; } // }

With this method defined, you can call BubbleSort() and pass the delegate instance that contains this method Beginning with C# 20, you simply specify the name of the delegate method (see Listing 128)
