>Can anyone explain what is the difference between 1.Default Data Session and 2.Private Data Session?
In default data session, a table opened by one form is also visible by another form. In private data session, tables opened by one form are "hidden" from other forms. This makes different forms act almost like different users. In the default data session you always run the risk of interference among different forms; therefore, your forms should use the private data session.
Similarly, if defined with a private data session, each form can have different settings for certain SET commands, e.g. SET DELETED.
>2. Where to use LockScreen? Because sometime when I click on any object the form slightly shake.
To postpone the updating of the form. Lock the screen updating, do some updates, then un-lock the screen again.
>3. Is it safe to use SP2 now? As I am not fully aware of it.
>4. In case of SP2 is there any major changes in project?
3 and 4, I don't know.
