C# windows forms book pdf

Manning Publications seemed to like the idea as well, and thus I suddenly found myself writing this book. In approaching the task, I set out to achieve two objectives. The first was to provide ample coverage of most of the classes in the namespace. I have been frustrated by many books that do not provide robust examples for a topic. So I try to provide detailed examples that demonstrate how Windows Forms classes can be used and manipulated in real applications.

A second objective was to present advanced user interface topics such as tree views and drag and drop. While the book spends a good deal of time on fundamental classes, such as menus and buttons, more than a cursory glance is given to some of the more complex controls available for Windows-based programming. The result of my proposal, these objectives, and a number of late nights is the book you see before you. I take a tutorial approach to application development by creating a common application throughout the book, and provide summaries of relevant classes and other topics that might be of further interest.

Hopefully, this approach provides enough detail to demonstrate how Windows-based applications are put together with the. A rectangle is composed of width and height.

The area of rectangle is calculated multiplying the width with height. Two books are created, specified and printed. The example below shows two ways to represent a string o je t. WriteLine s1 ; Console.

An example of using the IndexOf method is given below. Basically it returns a value different of - if the dog a e is fou d i the st i g. IndexOf "dog"! WriteLine "string contains dog! This will separate all the words. Therefore, exceptions are associated with error conditions that could not be verified during program compilation. For each exception that can occur during code execution, a block of handling actions an exception handler must be specified.

The structure of exceptions handling is given in Figure Figure 10 — Structure of exceptions handling Arora, Two categories of exceptions exist: i exceptions that are generated by the application; and ii those generated by the runtime.

All exceptions the derived from System. Exception class like indicated in Figure FieldAccessException — handles the errors generated by invalid private or protected field access. The appli atio ill lau h a e eptio sa i g System. DivideByZeroException: Attempted to di ide ze o. It is used to personalize exceptions according to programming needs.

To do this, we need to inherit Exception class. In the example below a custom exception was created to guarantee that all ages are greater than This class can be used to perform synchronous and asynchronous read and write operations. In the example below we used the ReadByte function to write in the console the contents of a file. In the end the file is closed using the close method. An example of using the StreamReader class is given below. In this example all lines of the file are read and written in the console.

Close ; f. For that, we can use the StreamWriter class. Also in this situation two methods can be used: i write ; and writeln. In the example below we write a single line of data into the file. WriteLine "hello visual c " ; s. Close ; Console. WriteLine "File created successfully. For instance, we can use it to create, delete and read files. FileInfo class also provides some useful proprieties and methods. In the example below we use FileInfo class to create a new file and add text to it.

WriteLine "This text is written to the file by using StreamWriter class. On the contrary of arrays, which have size limit, collections can grow or shrink dynamically. There are several types of collections, such as lists, stacks, queues, dictionaries or hashsets. In the example below we use a list to store elements. The add method is used to insert new elements in the list.

Add "Tom" ; names. Add "Lewis" ; names. It stores values on the basis of an unique key. It can be used to easily search or remove elements. In the example below we create a new dictionary and we associate three elements to it. Add "1","Tom" ; names. Add "2","Peter" ; names. WriteLine kv. The first step is to define a new SqlConnection instance that takes a connection string as argument.

When the connection is established, SQL Commands will execute with the help of the Connection Object and retrieve or manipulate the data in the database. Once the Database activities are over, Connection should be closed and release the Data Source resources. Forms; using System. Open ; MessageBox. Show "Connection Open!

Show "Cannot open connection! It is a good approach to avoid SQL Injection. Add new SqlParameter "0", 1 ; 4. In C it becomes possible to create, read and edit content of an XML document. We start by presenting the following example of an XML file. Load "Pessoas. Parse x. Attribute "codigo". Attribute "nome". Attribute "telefone". Add new XAttribute "codigo", p. ToString ; x. Add new XAttribute "nome", p. Add new XAttribute "telefone", p.

Add x ; xml. Save "Pessoas. Equals codigo. First ; if x! The element is edited and saved on the same XML file. Equals pessoa. SetValue pessoa. Save "Student.

Save "Student1. Scenarios 5. All these elements are defined in the main function. Two elements are calculated and written in the console: i the value of the price with discount; and ii the final price of the product.

The first thing to do is to receive a number from the console. For that we use the Console. ReadLine method. After that a for loop is created to test if the number can be divided by one of its divisors.

On the end, if the flag is still equal to zero, then we can assume that the number is prime. Parse Console. Write "Number is not Prime. Write "Number is Prime. The algorithm for performing it is composed of the following steps: 1. Ext" ; [System. DllImport "shell Use the WebBrowser Control into your form. Soumyaansh were you able to fix the issue.
