Working With Arrays
- 1. REGULAR VARIABLES For each item of information that we wish to store we need to declare a seperate variable This can become very confusing if we have multiple items of the same type to store
- 2. To store 3 individual names we need to declare 3 seperate variables strName1 strName2 strName3
- 3. New method of storing information We can use a special type of variable called an "Array" to store multiple items in a single variable We declare an Array very similar to a variable Dim strName (5) as String The (5) represents the number of items that we wish to store in our array
- 4. strName(5) would look like this We refer to each individual cell in the array by its "INDEX" number An array starts with an index of 0
- 5. To place information into the first cell of the array we would do it as follows strName(0) = "Casey" To place information into the forth cell we would do the following strName(3) = "Roger"
- 6. Casey Roger To retrieve information from an array and display it to a label we would do the following lblOutput.Caption = strName( ) To display Casey we would write lblOutput.Caption = strName(0) To display Roger we would write lblOutput.Caption = strName(3)
