devart dotconnect sqlite-网络文件夹上的sqlite数据库问题

Question

我有使用sqlite的邮件服务器来存储用户帐户信息 我还创建了一个应用程序（在另一台计算机上）来直接编辑/插入用户数据库，而无需打开邮件服务器GUI来执行此操作。 在邮件服务器升级到新版本并以wal模式连接到sqlite db之前，它运行良好。 然后，每当我通过devart dot连接sqlite连接sqlite并编辑用户数据库时，db崩溃并丢失了所有用户信息，db文件似乎已损坏。 我还发现沃尔玛模式可能不适用于网络文件夹。 https://www.sqlite.org/wal.html 但是这里的任何人都可以帮助我解决这一问题的最佳方法 在这种情况下，我真的需要编辑sqlite数据库 非常感谢
