Lesson 2 Objectives Objects – Range –Selection –Active Sheet Methods –Select Properties –CurrentRegion –Sort –Name

Objects, 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

Variables A variable is a name given to hold data. When a procedure uses a variable the current ‘value’ is used

Option 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

Loops For Next Loops If Then If Then Else Case Do Loops –Do While –Do Until

For Next Sub ForNext Loop () For Counter = 1 to 10 [Step 1] Code is written here Next Counter – continues to collect iterations as a count End Sub

If…Then Syntax

If…Then…Else Syntax

Use a Do Until…Loop Sub DoUntilLoop () Do Until ActiveCell = “” Code is written here Loop End Sub

Case Is… Syntax

Find first blank row at the bottom of a list Open the file Our Company Create a Sub procedure named Database Sub GoToBottom() ‘ Goes to the first blank row in an Excel list ActiveSheet.Cells(Rows.Count,1).End(xlUp).Offset(1).Select End Sub
