open the workbook, go to the VBE (Alt+F11), in the project explorer, click
on the project, then right click on the ThisWorkbook entry for that
workbook. Select view code. In the resulting code module, in the left
dropdown at the top, select workbook, and at the right dropdown select open.
At any point, the sub
Private Sub Workbook_Open()
End Sub
will appear in the module. When it does, call your macro from there
Private Sub Workbook_Open()
MyMacro
End Sub
That fires whenever a workbook is opened as long as events are enables.
