Subject: [comtypes-users] getting successful HRESULT values from
comtypes
Calling COM methods is straightforward just like with other
Python objects. They can be called with positional and named arguments.
Arguments marked [out] or [out, retval] in the IDL are returned
from a sucessful method call, in a tuple if there is more than one. If
no [out] or [out, retval] arguments are present, the HRESULT returned by
the method call is returned. When [out] or [out, retval] arguments are
returned from a sucessful call, the HRESULT value is lost.
If the COM method call fails, a COMError exception is raised,
containing the HRESULT value.
Is it true that there is no way to get a successful HRESULT from a call
that has [out] variables? An example is a function that can timeout, it
may return either S_OK (0) or S_FALSE (1), an the difference between the
two is important!
Is there anyway for me to retrieve that 'lost' HRESULT?
