Ok,
I have added this function right after sqlite3_step, that does the
prepared insert statement.
int nReturn = sqlite3_step((sqlite3_stmt*)(*start));
int autocommit = sqlite3_get_autocommit(m_pDatabase);
if (autocommit == 0) {
wxLogError(_("Warning: Database is not in autocommit mode.\n"));
}
autocommit is always 1. Also I have thested the following:
Open the application and opening the form to display first row -> no
jornal file is opened, because no write is yet done.
Adding some rows and navigating forward and backbackward -> jornal
file is opened and I can see my data in the application.
Now I will try to use pragma database_list; but I need to restart my
box.
So I will mail the result later :-(
