Steps Involved : 1. asp.net mvc pdf editor One of the great appeals of hacking is the practical way in which it builds on itself New skills become old skills, but not before they've provided a hacker with the foundation for a bigger and better "bag of tricks" and a more sophisticated way of hacking While the word hacking itself implies that a person spends time chopping away at something, about the only thing that a high-level hacker hacks at in this sense (using techniques I'll explain shortly) is a password Once a hacker has an account and password that allow him access to a computer, his hacking becomes the type of planned and deliberately executed activity that I tried to illustrate in the preceding story At this point, hacking is hands-on learning and testing, an exciting enterprise that depends on experience, skill, and a knowledge of computers and computer operating systems. itextsharp print pdf to printer c#, upc internet recenze, word pdf 417, .net data matrix barcode, ean 128 word 2007, .net upc-a reader itextsharp remove text from pdf c# iText 5-legacy : How to remove text from a PDF ?

A private member, though, is not persistent and doesn t survive postbacks. For this reason, in the get accessor of the property you need to check _dataItem for nullness and create a new instance if it is null. The code contained in the get accessor of a property runs whenever that property is invoked. As you ll see in a moment, the preceding code ensures that no access to DataItem results in a null object exception and that the state of the object is restored correctly after each postback. Most of the control properties we ve considered thus far use the ViewState container to persist the values. Why should we not store DataItem or style properties in the same way Is there anything wrong with the following code itextsharp remove text from pdf c# Changing existing text in a PDF using iText – Sampath LK – Medium

Deleting ... // NB: for this code to work, GaugeBarDataItem must be // a serializable type public virtual GaugeBarDataItem DataItem { get { var o = ViewState["DataItem"] as GaugeBarDataItem; return o new GaugeBarDataItem(); } set { ViewState["DataItem"] = value; } } Actually, nothing is wrong with the code per-se but consider for a moment view-state size and performance. Saving a class type directly in the ViewState container results in the object being serialized using the binary formatter. The BinaryFormatter class the standard way to serialize managed objects in .NET applications is not particularly fast and is designed to save the entire state of the object, including both public and private members, both simple and complex. The use of the BinaryFormatter increases the response time for each request and generates a larger view-state output. By customizing the view-state serialization, you obtain much faster code and save exactly the information you need to save. As a rule of thumb, you should use the ViewState container to store property values if the type of the property is primitive a string, numbers, Boolean values, colors, dates, bytes, and arrays of any of these types. Reference types (for example, custom classes) should be serialized by implementing IStateManager and exposing the property via a get accessor like the one shown previously. As far as control development is concerned, this is commonly required for styles and data item properties. A control that has properties that take advantage of custom view-state serialization must override the SaveViewState and LoadViewState protected methods. These methods are defined on the Control class, and they indicate how to save and restore the state of the control to and from the view state. The default implementation of both methods takes care of the contents of only the ViewState container object. 17.
