Workbooks Use the Workbooks property of the “Excel.Application”

object to return the Workbooks collection.

Dim objAppXL

Set objAppXL = CreateObject(“Excel.Application”)objAppXL.Visible = False

With objAppXL.Workbooks.Add ‘--- Create an new empty workbook..Open “bugs.xls” ‘--- Open an existing workbook..Close ‘--- Close all open workbook.

End With

objAppXL.QuitSet objAppXL = Nothing

7

Workbooks Use the Workbooks collection with an index or a name to

reference a workbook.

‘--- Set focus on the firstopened/created workbook.objAppXL.Workbooks(1).Activate‘--- Set focus on the bugs.xls workbook.objAppXL.Workbooks(“bugs.xls”).Activate

You can also use the ActivateWorkbook property.

‘--- Set focus on the firstopened/created workbook.objAppXL.Workbooks(1).ActivateobjAppXL.ActiveWorkbook.Author = “Dani V.”

8

Workbooks Use the Workbook – Example

objAppXL.Workbooks.Open “\\zeppo\FT_QA\bugs.xls”objAppXL.Workbooks.SaveAs “C:\bugs_local.xls”objAppXL.ActiveWorkbook.Close

objAppXL.Workbooks.Add.ActivateobjAppXL.ActiveWorkbook.Subject = “sales 2004”

9

WorkSheets Use the Worksheets property of the workbook collection to

return the Worksheets collection.

‘--- Show the number of worksheets in the workbook.

MsgBox objAppXL.ActiveWorkbook.Worksheets.Count

10

WorkSheets Use the Worksheets collection with an index or a name to

reference a worksheet.

‘--- Activate, print and save the first worksheet

objAppXL.ActiveWorkbook.Worksheets(1).ActivateobjAppXL.ActiveWorkbook.Worksheets(1).PrintOutobjAppXL.ActiveWorkbook.Worksheets(1).SaveAs “x.xls”‘--- Delete, the “Sheet 3” worksheetobjAppXL.ActiveWorkbook.Worksheets(“Sheet3”).Delete

You can also use application object’s ActivateWorksheet property‘--- Set focus on the first opened/created workbook

objAppXL.ActiveWorkbook.Worksheets(1).ActivateobjAppXL.ActiveWorksheet.PrintOut

11

Worksheets Use the Worksheet – Example

Dim objWshXLSet objWshXL = objAppXL.ActiveWorkbook.Worksheets(1)‘--- Perform a calculation.

objWshXL.Range(“A1:A3”) = “1”objWshXL.Range(“A4”) = “=Sum(A1:A3)”objWshXL. PrintOut

12

Ranges and Cells You may want to reference cells or a range of cells for doing

something such entering a formula or changing the format. A Range can be also a single cell. Example

‘--- Show the number of worksheets in the workbook.

objWshXL.Range(“A1:A3”).Font.Bold = True

13

Ranges and Cells

Range(“A1”) Cell A1. Range(“A1:B5”) Cells A1 thorough B5. Range(“C5:D9,G9:H16”) A multiple area selection. Range(“A:A”) Column A. Range(“1:1”) Row 1. Range(“A:C”) Column A thorough C. Range(“1:5”) Rows 1 thorough 5. Range(“1:1,3:3,8:8”) Rows 1,3, and 8. Range(“A:A,C:C,F:F”) Columns A,C, and

14

Ranges and Cells Referencing cells:

‘--- Show the number of worksheets in the workbook.

objWshXL.Cells(6,1) = “10”objWshXL.Range(“A6”) = “10”

Dim iFor i = 1 to 20

objWshXL.Cells(i,3) = iNext

15

Ranges and Cells Referencing cells:

‘--- Show the number of worksheets in the workbook.

objWshXL.Cells(6,1) = “10”objWshXL.Range(“A6”) = “10”

Dim iFor i = 1 to 20

objWshXL.Cells(i,3) = iNext

16

Ranges and Cells Referencing rows and columns:

Rows(1) Row one. Rows All the rows on the worksheet. Columns(1) Column one. Columns(“A”) Column one. Columns All the columns in the worksheet.

Example

‘--- Setting the fone of first row to be bold.

objWshXL.Rows(1).Font.Bold = True

17

Ranges and Cells Referencing a named range:

‘--- Font all range cells red color.

objWshXL.Range(“salaries”).Font.Color = RGB(255,0,0)

Referencing all cells: ‘--- Clear all worksheet’s cells.

objWshXL.Cells.ClearContents

18

Ranges and Cells Looping through a range of cells:

‘--- Go over all cells in a range.

For Each c In objWshXL.Range(“A1:D10”).Cellsif Abs(c.Value) = 0.01 Then c.Value = 0

Next

Selecting cells: objWshXL.Range(“A1”).Select

objWshXL.ActiveCell = “Hello”

objWshXL.Range(“A1”) = “Hello”

Ranges and Cells

Used as a container for Microsoft Excel worksheet functions that can be called from VBScript.

Example:

‘--- Find the minimum value within a range.

Dim theRange, minVal

Set theRange = objWshXL.Range(“A1:C10”)minVal = objAppXL.WorksheetFunction.Min(theRange)MsgBox “The minimum is: “ & minVal
