The Microsoft Exchange Server Event Service supports folder events that an application's code can use to respond to user actions and timer events.
The CML/LitCrit application uses two of these events to perform certain tasks, as shown in the following table.
| User action | Event triggered | Tasks supported |
|---|---|---|
| Outlook user has posted a new critique. | Folder_OnMessageCreated | Route the critique to an administrator for approval, delete the pending critique from the folder, and update the FmLib database. |
| Administrator has approved a critique. | Folder_OnMessageCreated | Post the approved critique in the public folder and update the FmLib database. |
| Administrator has rejected a critique. | Folder_OnMessageDeleted | Move the approved critique to the public folder and delete it. |
| Administrator or Outlook user has deleted a critique. | Folder_OnMessageDeleted | Delete the critique's record from the FmLib database. |
| Outlook user has edited his or her own critique. | Message_OnChange | Update the critique's record in the FmLib database. |
The tasks listed in this table are performed by the server-side Critique COM component. The following topic, Server-Side Critique COM Component Tasks, describes its actions in more detail.
