Can I access a vault from several applications at once?

Assuming all of the applications utilize the CBVault component, the same vault can be open in multiple applications simultaneously, but only if each one has opened it in read-only mode(which is controlled by the ReadOnly property). Such an application cannot open a vault in read-write mode if another application has it open in read-only or read-write mode; nor can it open it in read-only mode if another application has it open in read-write mode. This behavior is by design.

Alternatively, it is possible to create a server process that opens the vault and then services requests from client applications.
