Subject Re: [IBO] LiveMode - read this Jason.

Remember a previous discussion about this "rights thing" ? Now some IBX
defenders on my Interbase-BR list are saying that IBX has the answer and IBO not

I think something similar would be interesting to IBO people using ROLES...
it would make the life easier for them.

From the IBX 4.52 README file :

2. New Property - IBDatabase, IBQuery, IBTable - LiveMode, public, Set of TLiveMode, read-only.

Starting in 4.5 IBX should better support Roles. If you have an InsertSQL, ModifySQL,
DeleteSQL and RefreshSQL assigned, when the Dataset is prepared the LiveMode
property will reflect what permissions were granted by the server. LiveMode is a set with
the following possible values

(lmInsert, lmModify, lmDelete, lmRefresh)

So if your user does not have insert privledges then LiveModes would have
[lmModify, lmDelete, lmRefresh] and CanInsert will return false. IBX will stop
you from going into InsertMode if lmInsert is not part of the LiveMode set.

You can query LiveMode to determine the roles granted, or normally just let IBX
handle the stopping of editing, inserting etc. as needed.
