Add printer wizard sort issue

In Vista Beta2 Build 5472, install through “Add Printer Wizard
Installation”, as the picture below, Vista add a new property for this
“SysListView32” control -- LVS_SORTASCENDING. Then all the names of the
printers are sort ascending. But in other OS before Vista, this
“SysListView32” control do not have this property. So for example, when you
install through “Add Printer Wizard Installation”, both XP(2K) and Vista, the
content in the “SysListView32” is not consistent through the names.
On the other hand, every vendor has its own name order for the printers,
such as from older to newer. So, this property (“LVS_SORTASCENDING”) will
change the result which we need.
So, We want to know more about this new property, is it the new property or
it will be masked to consistent with the OS before in next version.
