– Range– Selection– Active Sheet

Methods– Select

Properties– CurrentRegion– Sort– Name

Objects, Methods, & PropertiesObjects, Methods, & Properties Objects have properties that govern their

appearance and behavior– Name of worksheet

Methods govern the action the objects perform– Protect a worksheet

Properties govern how the objects respond to a user action– Procedure is executed when the event occurs

VariablesVariables

A variable is a name given to hold data.

When a procedure uses a variable the current ‘value’ is used

Option Explicit and Dim StatementsOption Explicit and Dim Statements

Using Option Explicit in a module helps maintain the integrity of each variable.

Dim statements are a way to define variables in a procedure

Ex. Dim NumberOfEmployees As Integer

Unit 5 ObjectivesUnit 5 ObjectivesCreate a User Defined Function

(UDF)– Declare a variable– Perform a calculation

User Defined FunctionsUser Defined Functions Begin with the keyword Function

– The first line of code includes the function name as well as any arguments

– Arguments are enclosed in parentheses and separated by commas

– The code between the first and last lines perform the mathematical calculation

– The last line of code must return the calculated answer to the name of the function

End with the keywords End Function
