Hi

I have quite a complicated add-in the causes strange errors if i open Excel by opening
a .xlsm file. I need to determine if the ActiveWorkbook is a .xlsm file.
How do I do this?

    Private Sub ThisAddIn_Startup() Handles Me.Startup

        If Globals.ThisAddIn.Application.ActiveWorkbook.FileFormat.ToString <> "52" Then
            oAddInStartUp()
        End If

    End Sub
