Application.ThisWorkbook (Excel)

Returns a Workbook object that represents the workbook where the current macro code is running.

Use this property to refer to the workbook that contains your macro code. ThisWorkbook is the only way to refer to an add-in workbook from inside the add-in itself. The ActiveWorkbook property doesn't return the add-in workbook; it returns the workbook that's calling the add-in. The Workbooks property may fail, as the workbook name probably changed when you created the add-in. ThisWorkbook always returns the workbook in which the code is running. For example, use code such as the following to activate a dialog sheet stored in your add-in workbook: ThisWorkbook.DialogSheets(1).Show This property can be used only from inside Microsoft Excel. You cannot use it to access a workbook from any other application.

Dim wbThisWorkbook As Workbook
Set wbThisWorkbook = ThisWorkbook
