conflict between sqlserver and sqlserverCe

[cirollo]

Hi, I opened a new thread because the old thread title can make confusion...

finally I made the connection from a winCE PDA using in SQL 2008 the main instance and installing on the device the proper SQLClient CAB.

But, after doing the last operation, now I see the connection, but I get this error message:

An error occured on sub _mainmodule_app_start.

The database file is locked
database is locked
Continue?

This is my sub app_start, I think is related to the table rilevazioni that is onboard the device (is a sqllite table)
Infact, my program uses a local table to store data, that are transferred to the remote (network) sql at the user wish.

If I comment the lines regarding this local table, everything works, but this cannot be the desidered functionality.

Any idea about this error?
