Excel 2003 has these perky little green triangles that will expand to show detailed error messages for built-in functions. Is there a way that I can communicate an error other than #VALUE or #N/A from my custom C++ add-in function? If there is an answer from VB that would be ok too

Thanks

You can return other error XLOPERs like #NUM or #NULL but there seems to be
no way to return an error message. For ManagedXLL, I have been using a
separate window to log such messages.
