you simply have to implement the function Open of your
workbook, and call your macro as following

Private Sub Workbook_Open()
Call yourMacro

End Sub

Hi everyone!

I would like to know how could I run a macro
automatically
when a user opens an Excel file. That is, when someone
doubleclick the file on the desktop (for example), the
file opens and runs a specified macro.

Thanks in advance!
