Not according to the docs:

https://docs.microsoft.com/en-us/sql/ado/reference/ado-api/position-property-ado?view=sql-server-2017

  But according to the typelib, the single Position parameter is
a long. Type ADO_LONGPTR. That seems to indicate
a long that's actually a pointer to the stored value,
which seems odd. In any case, the problem seems to
be with VBS. That would explain why it returns "the
parameter is incorrect" when I try to set it. It's expecting
a long.


  This morning I came across a rant from Eric Lippert.
Remember him? He used to post condescending, hammy
advice about scripting. Microsoft breaks links to recent
docs and patches, yet Eric Lippert's rants from many years
ago are still online:

http://blogs.msdn.com/ericlippert/comments/410127.aspx

  He expresses the basic philosophy that Microsoft had
with Windows Script Host: Provide simple things that
coprporate IT needs, but don't make it too functional.
If all else fails, obfuscate the docs and give obfuscating
advice. Part of that philosophy was to block any file
access other than text, mainly for the purpose of logs.
From the linked page:

"I have been asked many times over the years if I know of a scriptable 
object that can read-write true binary files in all locales. I do not."
