hi, How to open Password Protected Pdf file directly in adobe reader when password is provided through code. For each pattern type, you implement a pair of classes that derive from Pattern and PatternEditor. The classes derived from PatternEditor will implement only the Saved event. The classes derived from Pattern will implement the abstract members and add members for creating new instances. Any public members that you add to a derived class can be accessed only by using a reference of the derived class type. Because we want to use the classes polymorphically, through a base reference, it doesn t make sense to add public members to the class. But because we ultimately have to create instances of the Pattern-derived classes, each class derived from PatternEditor needs a custom constructor that accepts an instance of the Pattern-derived class and a member to store that instance. Create the DrawnPattern class The underlying structure of the drawn pattern is an ordered collection of points in a 60by-60-pixel grid. The user creates the pattern by drawing a line from one point to the next in connect-the-dots fashion. The following illustration from a test version shows the list of points and the resulting pattern. c# itextsharp pdfreader not opened with owner password: Code for making pdf to password protected pdf in c# windows ... how to generate password protected pdf files in c# Create password protected PDF using iTextSharp, C# and VB.Net in ...

A data warehouse stores stable, verified data values. You might find it helpful to compare some of the most important differences between a data warehouse and a transaction database. using special rules-based workflow attributes, which are listed in Table 12-5. The following code shows one of these attributes in action: A transaction database helps people carry out activities, while a data warehouse helps people make plans For example, a transaction database might show which seats are available on an airline flight so that a travel agent can book a new reservation A data warehouse, on the other hand, might show the historical pattern of empty seats by flight so that an airline manager can decide whether to adjust flight schedules in the future A transaction database focuses on the details, while a data warehouse focuses on highlevel aggregates For example, a parent purchasing the latest popular children s book doesn t care about inventory levels for the Juvenile Fiction product line, but a manager planning the rearranging of store shelving may be very interested in a general decline in sales of computer book titles (for subjects other than SQL Server 2005).
