Parameters

Channel

Reference to ChatChannel object to which the access entry is added.

Entry

Reference to ChatUser object representing member whose access mode is changing.

Mode

A value defined by the CHAT_USER_MODE enumeration. Indicates the intended user mode during pre-update notifications, and defines the new user mode during post-update notifications.

Value

A Boolean value that defines the intent of the mode change. True if member is gaining rights, False if losing them.

PostUpdate

False if this is a pre-update notification. True if the new user access mode has been changed on the server.

Cancel

Return value. Set to non-zero during the pre-update notification to cancel the operation.

Remarks

This notification is triggered whenever a member gains or loses owner, host, or voice rights in a channel. No OnChangedMember event will occur with Mode set to CHAT_CHANNELMEMBER. To monitor for changes in channel membership you must bind to the OnAddMember and OnRemoveMember channel event notifications.

The extension can modify the contents of Value during the pre-update notification.
