NET is an update to Visual Basic that targets Microsofts . It is the most productive tool for rapidly creating a wide range of Windows, Web, Mobile, and Office applications built on the . The Visual Basic language is designed to be human readable and accessible to everyone from novice programmers to advanced system architects. NET Framework, which guarantees that programs written in Visual Basic run with unsurpassed scalability and reliability. NET languages such as Visual C#, Visual J#, or Visual C . NET in a simplified manner rather than in a complex way.

NET has a lot of similarities to Visual Basic but also some differences. NET is an object-oriented language, which supports the abstraction, encapsulation, inheritance, and polymorphism features. Net programmers with the ability to create fully object oriented programs (OOPs), just like the ones created using Java, C# or C . Net will interoperate seamlessly with programs written in any other . I hope this site will help you to acquire the skills and knowledge necessary to develop various types of applications in VB.

Fill(customers, "Customers") // Assumes that connection is a valid Sql Connection object. Customers", customer Connection); Ole Db Data Adapter ord Adapter = new Ole Db Data Adapter( "SELECT * FROM Orders", order Connection); Data Set customer Orders = new Data Set(); cust Adapter. Fill(customer Orders, "Orders"); Data Relation relation = customer Orders. The following example uses the MSData Shape Provider to generate a chapter column of orders for each customer in a list of customers.

string query String = "SELECT Customer ID, Company Name FROM dbo. A Using connection As Ole Db Connection = New Ole Db Connection( _ "Provider=MSData Shape; Data Provider=SQLOLEDB;" & _ "Data Source=(local); Integrated " & _ "Security=SSPI; Initial Catalog=northwind") Dim adapter As Ole Db Data Adapter = New Ole Db Data Adapter( _ "SHAPE " & _ "APPEND ( AS Orders " & _ "RELATE Customer ID TO Customer ID)", connection) Dim customers As Data Set = New Data Set() adapter.

String Builder and String class String A string is a sequential collection of Unicode characters that represent text. Concat method concatenates one or more instances of a String. Write Line (string1); string string2 = "Hi " "This is Jitendra ";string2 = "Sampathi Rao."; Console. Every time you use one of the methods in the System. String Builder class can be used when you want to modify a string without creating a new object. While coding, we look for classes that can reduce manual operation.

String is a class that belongs to the namespace System. String concatenation can be done using the ' ' opearator or the String. Sample code string string1 = "Today is " Date Time. Write Line(string2); String Builder String Builder is a class that belongs to the namespace System. String class, you create a new string object in memory, that requires a new allocation of space for that new object. For example, using the String Builder class can boost performance when concatenating many strings together in a loop. What is the difference between array and array list? For instance if you want to sort the values in an array then you need to do the manual operations.

To edit the data in your Data Table and save changes back to your database you will require an Update Command for you Data Adapter.

Something like this :- SQLConnection connector = new SQLConnection(@"Your connection string"); SQLAdaptor Adaptor = new SQLAdaptor(); Updatecmd = new sql Db Command("UPDATE YOURTABLE SET FIELD1= @FIELD1, FIELD2= @FIELD2 WHERE ID = @ID", connector); Updatecmd.

It is used to execute the sql statements like update, insert, delete etc.

This is because accessing the database, locating and processing the data, and then transferring the data to the client is time-consuming. For most applications, these provide a convenient representation of data source information.

Pulling all of the table to the client also locks all of the rows on the server. However, this representation may cause a problem when the data type in the data source is a SQL Server decimal or numeric data type. NET Framework is created for the chaptered column, and that table is filled with the columns and rows from the chapter.

Probably "Difference Between abstract Class and Interface" is the most frequent question being asked in the . In this tutorial, I will explain the differences theoretically followed by code snippets.

Theoretically there are basically 5 differences between Abstract Classes and Interfaces as listed below.3. Sample code String Builder number = new String Builder (10000);for (int i = 0; i The String object is immutable. Collections is a very important namespace in the programmer's perceptive.
