Am I right supposing nobody yet knows how to make to work ExecQueryAsync/ExecNotificationQueryAsync? I've searched the forum but found only questions (just the same I've got myself). I hope I missed something, but did I actually?
I am also having the same question and hoping someone will provide insight. I am using callMethodA to make a call to a WMI class method. It always returns 4096, which is Job Started, I have two options: one to make the call synchrounously so that I have return value in the OUT parameter right from the return, the other using the returned Job reference to query Job status and find a way to get the OUT parameter. I can't find solution for either.
