[gme-users] unknown error code after IMgaMetaAspect::get_Name

[Stefan Marte]

So I thought too (the reason btw is I think vba). interestingly, this
code works except for the get_Name part, whereas I get errors when
iterating through the array on a base 1. anyway, the effect is the same
for my code. have you got an idea what the error code could mean?
