Nature: Uncategorized Issue
Severity: 
Summary: The following improvemnts are suggested-	the COM iterator requires new methods-	introduce server handles to enable simple bridging to OPC, improve perfromace and memory consumption in server.-	introduce the OPC blob to enable simple bridging to OPC, improve perfromace and memory consumption in server. Add methods reset() and clone() to the Iterator.Replace ItemID with OPCHandle in all methods but create and validate entries.Add the blob.For more details se discussion below.

Actions taken:
December 14, 2001: received issue
October 23, 2002: closed issue
Discussion: 
Add methods reset() and clone() to Iterators.
Replace ItemID with OPCHandle in all methods but create and validate entries. Re-introduce the ServerItemHandle replacing the ItemID in read and write calls.
The new error code ERROR_INVALID_HANDLE is already defined by Microsoft and a new name must be created for this error code, i.e. ERROR_INVALID_DAIS_HANDLE.

Improved mapping between OPC and DAIS

The following improvemnts are suggested-	the COM iterator
requires new methods-	  introduce server handles to enable simple
bridging to OPC, improve perfromace and memory consumption in server.-
introduce the OPC blob to enable simple bridging to OPC, improve
perfromace and memory consumption in server. Add methods reset() and
clone() to the Iterator.Replace ItemID with OPCHandle in all methods
but create and validate entries.Add the blob.For more details se
