Serialization is the process of laying down the instance data one field after the other, often but not always in a file. If you re serializing several instances, the data for each instance is laid down in order. For example, if you re serializing the X and Y properties of two Point instances, A and B, the serialized file contains the values of A.X, A.Y, B.X, and B.Y, in that order. Deserialization is the process of reading that data back into a class instance. The actual bytes written and read are defined by an industry standard, by an application standard, or by you. Two well-known industry standards are bitmap files and Extensible Markup Language (XML) files. The sequence of bytes in a Microsoft Word file is an example of an application standard. You might define your own serialization format, perhaps by listing two numbers in a line of a text file to represent one (x, y) point. You use serialization for more than just saving instance data from one running of an application to the next. You ll also use serialization when you need to move data from one application to another. For example, you use serialization to move data from an application to the Clipboard. The .NET Framework provides several classes for serialization tasks. In the first exercise in this chapter, you ll use the BinaryFormatter and the XMLSerializer classes. Each class has its advantages and limitations, as the test application will demonstrate. The user interface of the application you ll create is shown in the following graphic: remove pdf password c#: Create password protected PDF using iTextSharp, C# and VB.Net in ... remove pdf password c# Itext 7 - PdfReader is not opened with owner password Error - Stack ...

ByteScout PDF SDK – C# – Remove Password and Protection From PDF . The user creates a list of triangles by defining each vertex of the triangle as a point (x, y). The user can then save the list of triangles in binary form or in XML form. Once the list is saved, the user can retrieve the data at a later time to restore the list of triangles. The design includes three classes: XYPoint, Triangle, and TriangleCollection. The Triangle class contains three XYPoint instances, and the TriangleCollection contains zero or more Triangle instances. The nesting of these classes lets you examine how serialization works and investigate the rules and conventions that apply to implementing serialization with the .NET Framework. Implementing Binary Serialization Binary serialization preserves the state of a class instance as a stream of bytes. This stream of bytes can be saved to a file, stored in memory, or moved across a network. By default, the byte stream contains the entire state of the object, including all the public and private fields of the instance. You can control which data is saved and restored by how to open password protected pdf file in c# set pdf file password at runtime in asp.net c# | The ASP.NET Forums

The workflow runtime, when it comes right down to it, is really there for one purpose supporting your workflow-based tasks. Workflow tasks, called instances when they are executing, are the heart of the workflow system. They re why the workflow runtime exists in the first place. A workflow instance is composed of one or more activities. (We ll look at the various activities starting in 7, Basic Activity Operations. ) The primary activity, or root activity is referred to as the workflow definition. The workflow definition normally acts as a container for the other activities that will actually do the work. Note 5 A workflow definition is what you ask the workflow runtime to execute, whereas an instance is an executing workflow definition. There is a distinct difference. One is executing and the other is not. However, I ll use the terms interchangeably throughout this chapter, and even in the rest of the book, because in the end we re interested in executing software, not just in writing it. Besides, instance rolls off the tongue more easily than does workflow definition. implementing the ISerializable interface. You might want to do this if there is information in the class that you don t want to make publicly available. The serialized data isn t readable as plain text, but it s not encrypted, either. Create the data classes The data model of this application includes the three classes: XYPoint, Triangle, and TriangleCollection. The user interface contains methods to create, delete, save, and load the instances created. 1. Create a new Windows application. Name it Serialize. 2. Add a new class named XYPoint to the project. 3. Add the integer X and Y properties to the class: 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. 16. 17. 18. 19. 20. 21. 22. 23. 24. 25. 26. 27. 28. 29. 30. 31. 32. 33. 34. public int X { get { return m_x; } set { m_x = value; } } // Visual C# private int m_x, m_y; public int Y { get { return m_y; } set { m_y = value; } Public Property Y() As Integer Get Return m_y End Get Set(ByVal Value As Integer) m_y = value End Set End Property Visual Basic Private m_x As Integer Private m_y As Integer Public Property X() As Integer Get Return m_x End Get Set(ByVal Value As Integer) m_x = value End Set End Property After completing this chapter, you will be able to: remove pdf password c# How to remove restrictions for a secured PDF ..?
