Correlation tokens are shared by name, so by assigning a correlation token with the same name to more than one correlated activity, you effectively bind those activities together from a data-conversation perspective The token s name is nothing more than a string, the value of which is meaningless It only matters that activities that share a correlation token share it by identifying the token using the same name A good question now is, Why didn t correlation tokens come into play earlier in the book After all, we certainly have used both CallExternalMethod and HandleExternalEvent activities in previous work The answer is we chose not to invoke correlation Correlation isn t required in all cases, and this was true for every workflow you created up until this chapter. how to create password protected pdf file in c#: C# PDF Password Library: add, remove, edit PDF file password in ... pdfreader not opened with owner password itextsharp c# PDF Security Remover - CodeProject

There's no PDF support in C# , you need to find a library to do that, probably paid, but free ones exist. When you have one-to-one mapping between the application and workflow instance, correlation is unnecessary overhead, and happily you can omit it and enjoy slightly increased performance Even when you have multiple workflow instances working with a single host application, you can work without correlation However, when you use correlation, WF prevents you from inadvertently mixing up data, and in many cases, this is a very desirable feature To activate the correlation infrastructure, you use specific WF-based attributes when you create your host communication interface The good news is the process to perform the host communication doesn t change by much The effect the change has on your workflow can be dramatic, however.. 1: how to merge two pdf files in c# using itextsharp: Merge PDF Files with New Method in C# - E-iceblue remove password from pdf using c# Password protecting a PDF file - Stack Overflow

I think you should be warned that such circumvention of the protection, in case you were not given a password , would be a violation of the right ... When designing and implementing properties, the following considerations apply: Properties can be read-write, read-only, or write-only. A read-write property can be retrieved and set by client code. A read-only property can only be retrieved and a write-only property can only be set. Write-only properties are rare. Developers tend to use write-only properties to send data to hardware devices so that the value sent to the device can t be retrieved later. Use a read-only property when the property is completely determined by other properties. For example, in a Rectangle class, the Length and Width properties can be read-write, but the Area property would be read-only. Reading the value of a property should have no side effects; no other instance data should change simply because it retrieved a property value. For example, a developer wouldn t expect the Width property of a Rectangle object to change just because the Area property was retrieved. Design properties so that they can be changed independently and in any order. If properties are dependent, use a method to set them. For example, if you need to set the LastName property of a Person object before you set the FirstName property, use a SetFirstAndLast function instead of two properties. A getter (the read part of a property definition) and setter (the write part of a property definition) of a property are conceptually simple methods that return or set values. The Length property of a rectangle object could be replaced easily with GetLength and SetLength methods. The advantage of using a property is the syntax. Rectangle.Length = 15 is obviously more elegant than Rectangle.SetLength(15). c# create pdf with password How to open the password protected pdf using c# - Stack Overflow

Security · C# Encrypt and Decrypt PDF file ... Remove password from the encrypted PDF document · Add Expiry Date to PDF Files in C# , VB.NET ... We'd better detect if a document is password protected or not before we try to open it. If you think about situations where a single host application might orchestrate multiple workflow instances, you will probably find that methods and events that pass data also pass some sort of unique identifier. An order processing system might pass a customer ID, or a packaging system might pass a lot number. This type of unique identifier is a perfect candidate for identifying unique instances of data, and in fact, that s precisely what happens. When you design the methods and events in your communication interface, you design into their signatures a data correlation ID. The data correlation ID doesn t have to be unique for all space and time, like a Guid. However, if it isn t a Guid, it must be used uniquely for the duration of the workflow instance s execution. Note 3 Data must be consolidated into a unified format and summarized across systems If you don t already have a data warehouse, a UDM can help you present the data in a unified and summarized manner 4 The business user must research the business rules associated with each system and apply them consistently Using a UDM, you can define those business rules in one place for consistent application An important component of the UDM in Analysis Services is the DSV Because the scope of analysis within a single cube can be more limited than the scope of a data warehouse, you can pick and choose the data that you need for the dimensions and for the cube by creating a subset view of the data warehouse This subset view is called a DSV. pdfreader not opened with owner password itextsharp c# Create password protected PDF using iTextSharp, C# and VB.Net in ...
