   I don't believe it runs Refresh, I've never seen any evidence of it when   
   using Profiler.   
   Under the covers, a command object is created (similarly as to when the   
   connection's Execute method is called) and parameter objects are appended,   
   typed based on that "best guess", which uses the types (or subtypes given   
   vbscript's restriction to Variant datatypes) of the passed values in making   
   that guess. Yes, theoretically, the best guess could be wrong, but in my   
   experience it never has been - at worst, an implicit conversion might be   
   required. Of course, my environment has always been very simple. And as long   
   as you properly type your VB objects, the chance of a bad guess that   
   requires more than a conversion from varchar to nvarchar, or float to   
   integer is slim.
