Workbook vs Workbooks

[lezawang]

Hi
Why in excel VBA there are 2 classes one is Workbook and the other is Workbooks. It is so confusing to have 2, what is the reason? Thanks

For each Workbook in Workbooks, Sheet in Sheets etc.

One is an object, one is a group of that object I believe

Yes, it is confusing until you start grasping the object hierarchy of Excel. Workbooks and Workbook are two different objects.

Application.Workbooks is a collection object that contains all the open workbook objects or items. The relationship might be pictured as:

Application
    |___Workbooks
            |___Workbook

An open workbook will belong to the workbooks collection. Similarly, a worksheet will belong to the worksheets collection.

Different objects have different properties. These are the MSDN pages listing the properties of the Workbook object and the of the Workbooks object.

Workbooks: https://msdn.microsoft.com/en-us/vba/excel-vba/articles/application-workbooks-property-excel
Workbook:https://msdn.microsoft.com/en-us/library/microsoft.office.tools.excel.workbook_properties.aspx

Thanks for your reply and help. The code below use WorkSheets(5) to clear the content of sheet5.
My questions:

1) why WorkSheets() is used not WorkSheet()? I was thinking to use WorkSheet(5).Cells.......
2) Cells is not property of WorkSheets()? so how the author called it from WorkSheets().Cells ??
3) Also ClearContents is not part of Cells but excel did not complain or give error message?
+++++

Private Sub CommandButton2_Click()
Worksheets(5).Cells.ClearContents
End Sub

Not sure what is meant here, clearcontents is used on a range, cells is a range.
