Hi there,
I don't seem to be getting the same problem here using ADO (type library 2.7).
Try using : Com.Properties("Page Size").Value = 1000
(without specifying 'Value=1000' I was getting 'this property is read only' from intellisense)
Bear in mind that you don't really need to set a page size as high as 10000 - as long as you set a page size, then all results will return. 1000 should be fine.
