I used MakePy to generate .py support for a COM dll. That created the
file
30D58DAF-B538-45F1-8EFF-F69ABA2BA798x0x1x13.py
I want to be sure that this file is present and so I used MakePy -i to
construct a call to gencache.EnsureModule().
This is what it said:
{30D58DAF-B538-45F1-8EFF-F69ABA2BA798}, lcid=0, major=1, minor=130, 1, 13)
But when I execute this code, it creates the support as a package,
that is, there is a _folder_ called
30D58DAF-B538-45F1-8EFF-F69ABA2BA798x0x1x19
(NB minor version is 19 not 13) with separate .py files for each
interface and class inside, and an __init__.py.
If the EnsureModule() call has not been called to generate the
package, then win32com.client.CastTo() fails when called with a
class-instance and interface defined in the COM dll. It complains that
it can't find the package ...x19.
Can anyone explain the version number difference (I realize that
19=0x13 but that doesn't help me understand it much), the
package/single file difference, and why Dispatch responds to the one,
but CastTo expects the other?
