2 Assessed Exercise 1 Working with ranges

3 Multiple representations Different thing in different cases Single cell Collection of cells The handle to the thing you want to work with

4 Many operations in Excel are range operations. Select, copy, format, enter values or formulas Important to automate range operations with VBA. Ranges can be absolute or relative The Range object has properties and methods. Use the Object Browser in the VBE to look up any specific property or method. For more examples of ranges in VBA look at the examples in the file Ranges.xls. 4

5 Use an address Follow Range with an address in double quotes: Range( A1:A10 ) Use a range name Follow Range with the range name in double quotes: Range( Sales ) Use the Offset property Use a Range object variable Use the End property (xldown, xlup, xltoright, xltoleft) You do not need to know the size of the range 5

6 You can refer to a range literally, using the Excel cell references in double quotes: MsgBox Range("B1:F1").Address MsgBox "The first score for the first employee is " & Range("B2").Value

7 You can apply a name to a range: Range("B1:F1").Name = "ScoreNames Then use the range: Range( ScoreNames").Font.Bold = True And remove names: ActiveWorkbook.Names("ScoreNames").Delete

8 You can refer to cells within a named range: Range("B2:F19").Name = "ScoreData MsgBox Range( ScoreData ).Cells(2,3).Value (returns the value in D3)

9 Select Select method is like highlighting Range( B2:F5 ).Select Activate Makes this cell live (only works on a single cell range, does not affect any selection ) Range( E3 ).Activate Can activate a workbook or worksheet Worksheets( Practice2 ).Activate As seen with macros can use ActiveCell and Selection as handles

10 Offset(rows,cols) is a property that allows you to refer to a cell offset from a range. For example: Activecell.offset(rows,cols); or Selection.offset(rows,cols); or Range("D12").offset(rows,cols) Use with ActiveCell and with.end(xldown)

11 By using A1 as an anchor, all the offset property can be used where the actual range is unknown or variable With Range("A1") Range(.Offset(0, 1),.Offset(0,1).End(xlToRight)).Name = _ "ScoreNames" Range(.Offset(1, 0),.Offset(1,0).End(xlDown)).Name = _ "EmployeeNumbers" Range(.Offset(1, 1),.Offset(1,1).End(xlDown).End(xlToRight)).Name = _ "ScoreData" End With

12 You can refer to columns or rows either in reference to the whole sheet or to a range or selection for example, Columns(2).select is as follows: The principle is the same for Rows. Rows(3) is the 3 rd row in the sheet.

13 This sub formats the cells in the range ScoreNames. Using With avoids repetition With Range("ScoreNames").HorizontalAlignment = xlright.interior.colorindex = 5 With.Font.Bold = True.ColorIndex = 3.Size = 16 End With.EntireColumn.AutoFit End With

14 Formulas Range( B20 ).Formula = =AVERAGE(B2:B19) Range( B20 ).FormulaR1C1 = "=AVERAGE(R[-18]C:R[-1]C)" Note R1C1 notation See Range9 for an example of applying a formula to several cells (like using autofill)

15 ActiveSheet.Rows(Rows.Count).Select MsgBox Selection.Count Sub Rangetest() MsgBox The current selection is & Selection.Rows.Count & _ rows high and & Selection.Columns.Count & columns wide End Sub Worksheets.count The number of worksheets in a workbook (file) Workbooks.count Columns.count Rows.count Cells.count The number of currently open files the number of columns in the current sheet the number of rows in the current sheet the number of cells in the current sheet

A region is a range of filled cells, bounded by empty cells. The current region is where the currently selected cell is: it includes all non-blank cells touching the current cell.

16 A region is a range of filled cells, bounded by empty cells. The current region is where the currently selected cell is: it includes all non-blank cells touching the current cell. As long as you have one cell in the region selected, you can press Ctrl-Shift-8 (i.e., Ctrl-*) to select the region This shortcut key corresponds to a line of code: Selection.CurrentRegion.Select

Use the wk03empscrnameranges file to complete the following tasks Name cell A1 as Title Name the headings in row 3 as Headings Name the employee numbers in column A as EmpNumbers Name the range of

17 Use the wk03empscrnameranges file to complete the following tasks Name cell A1 as Title Name the headings in row 3 as Headings Name the employee numbers in column A as EmpNumbers Name the range of scores as Scores With reference to the names above write a sub that performs the following tasks: Make cell A1 bold and size 14 Make the headings on row 3 bold, italic and right aligned Change the font colour for the employee numbers in column A to blue Change the background of the scores cells to light grey (Hint: use the Interior property) Enter the label Averages in cell A22 and make it bold Enter a formula in B22 that calculates the average. Copy the formula to C22:F22

18 For Each Loops

19 .Cells Used to refer to a particular cell. Range( A1:A10 ).Cells(3) refers to the third cell in the range Range( A1:A10 ).Cells(3,2) refers to the cell in row 3, column 2.Font Returns a reference to the font of the range. Can change font properties Range( A1:A10 ).Font.Bold = true.formula Returns or sets a formula in a range as a string. Range( A11 ).Formula = SUM(A1:A10).Interior Returns a reference to the interior of a cell Often used to change background colour Range( A1:A10 ).Interior.Color = vbred.name Returns or sets the name of a range. Range( A1:B10 ).Name = Sales 19

20 .Value Returns or sets the value in the cell. Default property for a Range object (can be omitted). Usually used for a single-cell range. unitprice = Range( A11 ).Value or unitprice = Range( A11 ).Offset Returns a reference relative to a range. The range is usually a single cell. Very useful property, used constantly in most applications. It takes two arguments: row offset and column offset. Range( A5 ).Offset(2,3) = start in cell A5, go 2 rows down, 3 columns to the right. Use a positive offset to go down and a negative offset to go up. Use a positive offset to go to the right and a negative offset to go to the left. 20

21 .Clear Deletes values and formatting from the range..clearcontents Deletes only values (and formulas)..copy Copies a range. One optional argument: destination. Range( A1:B10 ).Copy Destination:=Range( E1:F10 ).Paste Pastes clipboard contents to the range. Can have different arguments indicating how to paste. Range( E1:F10 ).PasteSpecial Paste:=xlPasteValue.Select Selects a range. Equivalent to highlighting a range in Excel. 21
