Hi stefan it seems your suggestion jogged my memory banks a bit. Here is what i came up with. It seems to work so far. var s : seq[string] = newSeq[string](extension_count) for i in 0 .. s.len: var f = extension_prop[i].extensionName.cstring s[i] = newString(256) s[i] = cast[string](f) extension = alloccstringArray(s)
and thank you for your help
