FIX: MSMQ: GetStreamedObject and GetStoredObject Return Error with VT_UNKNOWN

This article was previously published under Q241755
This article has been archived. It is offered "as is" and will no longer be updated.
Sending components that result in calls to either GetStreamedObject or GetStoredObject receive errors with incorrect HRESULT values.
MSMQ passes VT_UNKNOWN in the variant's type tag after a call to query interface. This is valid. The HRESULT should have been reset prior to returning, but it was not. This resulted in errors due to the HRESULT being set incorrectly.
