PdfReader not opened with owner password . Hi all, I am a bit confused about the following error: Exception occurred during event dispatching: ... Designing the SourceFile Class The class implemented in this chapter has been designed with these NET capabilities in mind: The DataGrid control can use an array as a data source If the type of the array is a class, the DataGrid control uses the public properties of the class as the columns To take advantage of these properties, you need to create a SourceFile class with LinesOfCode, FileName, ClassCount, and FullPath properties The data source for the DataGrid control will then be an array of SourceFile instances Because a SourceFile instance can make sense only if it s based on an existing file, you need to create a constructor that takes one string parameter, the filename The LinesOfCode, FileName, ClassCount, and FullPath properties are all dependent on the name of the source file It isn t reasonable for the client to be able to change these properties. pdfreader not opened with owner password itext c#: Code for making pdf to password protected pdf in c# windows ... how to open password protected pdf file in c# How to open Password Protected PDF using iTextSharp C# .Net ...

When you build correlated services, the CorrelationParameter attribute identifies by name the method parameter that is used to convey the data correlation identifier. For your interface methods, this means you must have a method parameter named using the same name as the correlation parameter name. But this can break down for events. If your delegate is created such that the correlation parameter is in the delegate definition, there is no problem. It s baked into the event handler s method signature just as if it were any other interface method. The problem arises when you use a delegate that includes event arguments, and those event arguments convey the correlated parameter. For example, imagine your correlation parameter was named customerID.

You will build a dimension in the next procedure that uses data from these three tables, so all three tables must be included in the DSV. In addition, you could add a Named Query to the table to reference data from these three tables without adding them explicitly to the DSV. A Named Query is analogous to a view in a relational database. You create a Transact-SQL statement to define the tables and columns that you want to combine into a single object. You need to create the data source view with at least one object before you can add a Named Query to it. 5. Click Next, and then click Finish. You have the option to change the default DSV name before completing the wizard. 6.

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 ... If the event that used this delegate were placed into your communication interface, the customerID parameter wouldn t appear in the event handler and WF would throw an exception stating correlation was misapplied when you executed your workflow. However, if MyEventArgs has a property that contains the customer ID, you can use the CorrelationAlias attribute to identify that. For this example, if the MyEventArgs customer ID property were named CustomerID, the correlation parameter s alias would be e.CustomerID. An important thing to keep in mind is that once you initialize a correlated data path for a single workflow instance, you cannot change the data correlation ID for the lifetime of the workflow instance without generating an error. For example, once you communicate with a workflow data associated with one customer ID, you can t later communicate data regarding another customer ID to the same workflow instance. What this means is that if your process involves creating customer IDs, such as when inserting information into new database table rows, you need to pre-create the customer ID. You can t allow the database to generate those for you because your communications would be initialized using no customer ID, or a default empty one, only to later begin using the newly created ID. The IDs in question would differ, and your workflow would throw an exception. So you ll make these properties read-only That leaves only the list of class names for you to make Again, this should be a readonly list Conveniently, Visual Basic allows you to define a property that takes a parameter You use this capability to return one class name, based on an index C# doesn t have a parameterized property, so you must implement a method to return a class name Later in this chapter, you ll see how C# provides an indexer construct to serve the same purpose The SourceFile class provides the following public members: Filename A read-only string property that returns just the name of the source file FullPath A read-only string property that returns the full path of the source file LinesOfCode A read-only integer property that returns the number lines in the source file that aren t blank and aren t comments. remove password from pdf using c# How to protect PDF with password using C# , VB.NET | WinForms ...
