MS Office Forum / Outlook / Programming Add-Ins / November 2003XP Add-in won't load in 2000
Hi, I have developed a COM add-in for Outlook XP that I am trying to load in Outlook 2000. In 2000, the module starts to load, but then throws the error "Run-time error '459': Object or class does not support the set of events". I suspect that this is due to the fact that one of the classes in my project (VB6) catches events from an Explorer object with events. When I comment out the "WithEvents", the program loads (but obviously doesn't function properly.), but if I leave the WithEvents in & comment out all of the event traps, the load still fails. I suspect this has something to do with the fact that on my development machine, I have Outlook XP, and set a reference to the Outlook 10 library. If I do not take advantage of any XP-specific methods, properties or events, then shouldn't I be able to do this? If so, how? I would like to reference the Outlook 9 object library, but that does not appear to be available on my development machine, even though the Office 9 library IS. Can someone explain to me how this is done? Thanks. Jon Rizzo Langan Engineering and Environmental Services, Inc. Hi Jon, > Hi, > [quoted text clipped - 20 lines] > Jon Rizzo > Langan Engineering and Environmental Services, Inc. Ms docs states that if you taget the lower possible version, your addin will work with newer ones. So, while you develop the addin, if you target 2000, and version 9 libraries, after that it should work with XP and 2003. So far with mine addin it is true. You just don't have to use any version specific functionality. As far as I know you can install different versions of Office on same machine, different folders, except Outlook. So you need to install only Outlook 2000 maybe, and to remove the XP version. Hope that helps Sunny Always develop addins using the lowest version you intend to support and don't use methods, properties or events that aren't in the lowest version. -- Ken Slovak [MVP - Outlook] http://www.slovaktech.com Author: Absolute Beginners Guide to Microsoft Office Outlook 2003 Reminder Manager, Extended Reminders, Attachment Options http://www.slovaktech.com/products.htm > Hi, > [quoted text clipped - 20 lines] > Jon Rizzo > Langan Engineering and Environmental Services, Inc. Thanks for the tip, I will try that. How do I reference the older type library from my development machine? Do I need to have outlook 2000 loaded on my development machine, or can I somehow reference version 9 of the library if Outlook XP is loaded on my development machine? The only one I see listed as an option is version 10.
