vbscript, check CDO.DLL

check CDO.DLL

Author	Message
J #1 / 3	check CDO.DLL Hello, I made a ASP page for our intranet that shows the free/busy-information of all employees. I have done this by querying Microsoft Exchange through a Mapi-session. After server maintenance the page suddenly stopped working. The cause was that after the maintenance the CDO.DLL was not registered anymore. Re-registering was easily done by: REGSVR32.EXE CDO.DLL but it took hours to find out this was the problem. What I want to do is building a check in the ASP-page to see if CDO.DLL is registered on the server and if is is not I display a message so we know immediatly what the problem is (and solve the problem in 1 minute). My question: Is there a way to detect CDO.DLL is registered on the server using VBScript? Help will be greatly appreciated. John

Either error trap on the CreateObject("MAPI.Session") or check the registy to see if the "MAPI.Session" progid is present (which mayso require error trapping depending on how you access the registry). -- Michael Harris Microsoft.MVP.Scripting Seattle WA US Technet Script Center http://www.microsoft.com/technet/scriptcenter/default.asp
