| | Object.Get vs direct retreival Hi all, I have a question relating to object propery caches and retreival and update methods. What is the difference between let's say: sInfo = oUser.get("info") and sInfo = oUser.info? If the property does not exist in the cache, do they both return the E_ADS_PROPERTY_NOT_FOUND code? In each case will sinfo be "Empty" or "Null"? Which is the proper method to use and which is the preferred method to use? Similar questions for the .put method. If the property does not exist in the cache and you need to create it, what's the proper way to do so? Thanks very much -- Tim. |

If you use sInfo = oUser.info then sInfo will be Empty if info has no value. Otherwise, they are the same. If you use Get you almost need to trap errors. I seldom use it as a result. -- Richard Mueller MVP Directory Services Hilltop Lab - http://www.rlmueller.net -- |
