This code shows you how to upload media files to the SQL Server Database to store it and then how to download it from the Database in your ASP.NET website using C#. First you have to create a database named “MediaDB” in your SQL Server. Then create a table named… Continue reading
The sub-procedure is a block of multiple visual basic statements within Sub and End Sub statements. It is used to perform certain tasks, such as changing properties of objects, receiving or processing data, and displaying an output. You can define a sub-procedure anywhere in a program, such as in modules,… Continue reading
A literal is a textual representation of a particular value of a type. The different types of literals in Visual Basic are: Boolean Literals – Refers to the True and False literals that map to the true and false state, respectively. Integer Literals – Refers to literals that can be… Continue reading
The variables that are based on reference types store references to the actual data. The keywords that are used to declare reference types are: Class – Refers to the primary building block for the programs, which is used to encapsulate variables and methods into a single unit. Interface – Contains… Continue reading
A parameter is a special kind of variable, which is used in a function to provide a piece of information or input to a caller function. These inputs are called arguments. In C#, the different types of parameters are as follows: Value type – Refers that you do not need… Continue reading
The variables that are based on value types directly contain values. The characteristics of value-type variables that are supported in C# programming language are as follows: All value-type variables derive implicitly from the System.ValueType class You cannot derive any new type from a value type Value types have an implicit… Continue reading
Keywords are those words that are reserved to be used for a specific task. These words cannot be used as identifiers. You cannot use a keyword to define the name of a variable or method. Keywords are used in programs to use the features of object-oriented programming. For example, the… Continue reading
The switch statement is a selection control statement that is used to handle multiple choices and transfer control to the case statements within its body. The following code snippet shows an example of the use of the switch statement in C#: switch(choice) { case 1: console.WriteLine(“First”); break; case 2: console.WriteLine(“Second”);… Continue reading
Identifiers are northing but names given to various entities uniquely identified in a program. The name of identifiers must differ in spelling or casing. For example, MyProg and myProg are two different identifiers. Programming languages, such as C# and Visual Basic, strictly restrict the programmers from using any keyword as… Continue reading
The while and for loops are used to execute those units of code that need to be repeatedly executed, unless the result of the specified condition evaluates to false. The only difference between the two is in their syntax. The for loop is distinguished by setting an explicit loop variable.
