Answer 1

检查文件路径：确保 msado15.dll 文件位于 C:\Program Files\Common Files\System\ado\ 目录下。如果文件不存在或位置不正确，您可以尝试使用正确的文件路径。

检查数据库连接字符串：请确保数据库连接字符串中的服务器名、数据库名、用户名和密码正确无误。如果您不确定这些信息，请与数据库管理员联系以获取正确的连接字符串。

检查数据库和表的存在性：确保数据库和表存在并且可访问。您可以使用其他数据库管理工具（如SQL Server Management Studio）来验证数据库和表的存在性，并确保您具有足够的权限访问它们。

检查代码逻辑：在您的代码中，有一些地方可能会导致问题。首先，您在打开记录集时使用了 adCmdTable 参数，这意味着您试图打开一个名为 "Employee" 的表。请确保该表存在，并且没有拼写错误。其次，您在异常处理块中访问了 pRstEmployee 对象的属性，但是在异常发生时，pRstEmployee 对象可能为空。您可以在访问 pRstEmployee 对象之前添加一个非空判断。
