So, what are variables??

Variables are place holders of a sort, they allow us to give a value to a name or word, There are different types of variables, some languages dont have different types example: Perl. But VB.NET does, the too types i am going to tell you about are integers and Strings.


Integers

Integers are just another way of saying numbers, so by now you can already see how a variable would work - name = 4, but in programming there is usually a symbol or command/function needed to declare that it is a variable and not a silly programming mistake, and Vb is no different. Do declare a variable in Visual Basic we type "dim". Let me show you a full example:



'dim', is letting the program know it is about to have a new variable name, the variable name is 'variable1', 'as integer' is declaring what type of variable it is, and '= 4' is the value the variable got assigned too. Simples.


Strings

String are variables that allow us to have words assigned top the name. Like with integers we must declare the variable, set the name, say what type and finally give it a value. To do this instead of using 'as integer' we use 'as string'. Here is an example:



Like before we have had to declare that we are using a variable and assign it a name so we are able to give reference later on in a source, but this time we chose to use string showing that we will be using more than just numbers, because we are using more than numbers we have to surround the value with "" (quotations) so it know that that is what the = is referencing too.


The End.


Hope you found this a very detailed look at variables in visual basic, and let me know if you would like me to bring you more tutorials like this.
