MS Office Forum / Outlook / Programming Add-Ins / June 2005Detect FolderChange, FolderDelete and FolderAdd
Hello, What is the recommended and effective way to detect any FolderChange, FolderDelete and FolderAdd event in OUtlook. That include when user right click on a folder and through context menu, add new folder, or delete or rename a folder. Is it event sink all availble MAPIFolder's folders collections when first started Outlook and add more event sink when there are new MAPIFolder added, unadvise related event sink when MAPIFolder remove. Then, later when exit Outlook, unadvise all one by one. (all the MAPIFolder). Please advise. thanks. What exactly (and why) are you trying to do?

I am trying to catch any FolderChange, FolderDelete and FolderAdd occur in Outlook. The current event model of OOM is that I need to sink each folder collection I am interested. The solution that I have is to advice and unadvice the MAPIFolder OnBeforeFolderChange but that only working on the Items Event and not to FolderEvent cause user can add/remove/rename folder through context menu. I trying to come out with a proper workaround for this. Any better approach?? thanks > What exactly (and why) are you trying to do? > [quoted text clipped - 20 lines] >> >> thanks. *WHY* are you trying to do this?

Thank you for your reply, The 0xf003 is for event ExplorerEvent::BeforeFolderSwitch which I already did for the attempt to detect the folder switch and sink on and off. The problem is that it can't detect the context menu (right click) function like rename, delete and add when user right click on a folder, the sink off/on for Folder collection is not accurate when user choose to use context menu to do rename, add and remove folder. The context menu click is non detectable by Outlook OOM event sink as far as I know. Any workaround? > You need to sink off of the explorer events.

For example folder change is > event 0xf003 in the explorer events. I just added an event sink (folder add) for my inbox folder and used the context menu to add a folder to my inbox folder. It caught the event no problem. Are you sure you sinked to the folder that you right clicked on? Yup, the event sink could detect. My problem is to set up the event sink to that particular folder. I need something dynamic. I am using BeforeFolderSwitch at the moment. My initial problem ------------------------ I need to detect any folder add event occur in Outlook. (in any folder collection). >I just added an event sink (folder add) for my inbox folder and used the > context menu to add a folder to my inbox folder. It caught the event no > problem. Are you sure you sinked to the folder that you right clicked on? What language? I have an ATL class that allows dynamic folder event sinks. Probably I should make it clearer. I could dynamically folder event sink, the classes are available in ATL I know . And the Outlook could detect the folder event (although, FolderDeletion could not detect the last folder deletion in a Folder collection, but that could be overcome with some algorithm) . The problem is that I could not accurately determine "when" should dynamically event sink for the needed folder collection. As you know, the befoforefolderswitch (which is the time to dynamically event sink) only occur if user open the folder, that is by left clicking a folder. If user choose to right click on a folder and through context menu do some folder stuff. There is no way to determine if the user is clicking on that particular folder. Therefore, the dynamic event sink approach could not be a right approach to achieve what I want, to detect any folder collection happen in Outlook. The CommandBarUpdate could detect the user right click but after some test, to my dissapointment, the event happen in an inconsistent manner. The ultimate approach that I could think of is to event sink all the folder collections in the Outlook and when there are Folder added/ remove. Then, the corresponding new folder collection will get event sink / unadvice. The only problem of me to this is the overhead it might cause, imagine there are many folders in Outlook. Anyway, thanks for your reply. > What language? I have an ATL class that allows dynamic folder event sinks. |
