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
