I’m not an expert in how MXS relates to dotnet yet, but .copyto [font=Verdana]requires its destination array to be 0-based, and Max arrays are 1-based. You could use the dotnet collection’s own supplied enumerator, thus …

                  [/font]


     	  dotNet.loadAssembly "System.Management" 
                     
     	  MOS_Class = dotNetclass "System.Management.ManagementObjectSearcher"
     	  myMOS	=   dotnetobject MOS_Class
                    
     	  myMOS.query.QueryString  = "SELECT * FROM Win32_DiskDrive"
     	  myMOC = myMOS.get()
                    
     	  myMOCEnum = myMOC.GetEnumerator()
                     
     	  myMaxArr = #()
                        
     	  while (myMOCEnum.MoveNext()) do(
                     		append myMaxArr myMOCEnum.Current   
     	  )
                     
     	 for myMO in myMaxArr do (
                  	   deviceid = myMO.GetPropertyValue("deviceid")
                  	   print deviceid
     	 )

               .. but maybe an expert will come up with a better way
