Visual Basic allows us to perform most operations available in Windows Explorer and DOS command line. Files While programming, you may want to at some point save data so they may be accessible for further use. Error Handling Errors can be caught, handled and raised. Procedures and Functions A function is a calling procedure or small part of a program that performs some specific task and returns a result for example the cosine function.

Data Types A datatype is a specification of the kind of information that a variable can hold, for example, a number or a piece of text. Arrays Arrays are used to group data items of the same type together, to make it easier to search and sort through this data. Regular Expressions Complex string matching and manipulation can be achieved using a fairly sophisticated technique of regular expressions. Built In String Functions Strings can be manipulated using simple string functions. They are very useful for communicating with human beings and for transferring data between programs and machines in text files and web pages. Strings Strings hold printable characters.

Loops Loops are control structures used to repeat a given section of code a certain number of times or until a particular condition is met. The flow of execution follows a particular branch like a fork in the road. Branching Branching occurs when the program makes a decision.
