Re: about COM _Enums

In COM you would normally user QueryInterface on the IUnknown returned to
get IEnumVARIANT. From that interface you could enumerate the items.
Usually, there's an alternative way to access the items of a collection.

Subject: [JAWIN] about COM _Enums

Hi all,

     I encounter problem about how to map COM _Enums
to
Java Enumerations.
     My java stub codes for a dll are generated by
JawinTypeBrowser.
     Please have a look following code:

    public IUnknown get_NewEnum() throws COMException
    {
         return (IUnknown)get("_NewEnum");
    }

    I have no idea how to use this 'IUnknown',
actually
I expect this method will return a type of java
Enumerations.
    I am not family with COM _Enums, anyone pls give
me
a help, thanks a lot!

Best regards,
Ken
