Question

我遇到了一些运行的Windows服务问题。我已经创建了一个新的测试服务，它创建了一个带有连接字符串的ODBCConnection，我已经多次验证它是正确的。每当我调用Open（）方法时，我都会收到以下错误：

Error: System.Data.Odbc.OdbcException (0x80131937): ERROR [08001] [Simba][SimbaEngine ODBC         Driver][DRM File Library]Invalid account name.
ERROR [IM006] [Microsoft][ODBC Driver Manager] Driver's SQLSetConnectAttr failed
ERROR [01000] [Microsoft][ODBC Driver Manager] The driver doesn't support the version of ODBC    behavior that the application requested (see SQLSetEnvAttr).

at System.Data.ProviderBase.DbConnectionInternal.OpenConnection(DbConnection outerConnection, DbConnectionFactory connectionFactory)
at System.Data.Odbc.OdbcConnection.Open()

我让服务以32位模式运行，DSN是在32位ODBC管理工具中创建的。我能够使用ODBC测试程序连接相同的连接字符串。我也可以通过命令提示符运行该服务，它将完美地工作。我尝试以具有最高权限的用户身份运行服务，但这没有帮助。有没有人对可能造成这种情况有什么想法？

这是正在运行的代码。我删除其他因素是非常基础的：

string connectionString = "verified connection string";
string query = "random query I know works";
OdbcConnection c = new OdbcConnection(connectionString);
 try
    {
        elog.WriteEntry("Opening odbc connection...", EventLogEntryType.Information);
        c.Open();
        elog.WriteEntry("Opened odbc connection...", EventLogEntryType.Information);
    }
    catch
    {
        c.Dispose();
        throw;
    }

ODBCConnection打开连接时出现问题
