VC的 CDatabase 连接 Sql Anywhere 5.0的问题，连接字符串应该怎么写 ( 积分: 200 )

我试过如下2个都不行
1.
ODBC;Driver=Sybase SQL Anywhere 5.0;DefaultDir=C:/SQLANY50/WIN32;Dbf=c:/MySoft/db/mysoft.db;Uid=abc;Pwd=efg;Dsn=""""
2.
"Provider=MSDASQL.1;Persist Security Info=False;Database=MySoft;
User ID=abc;Data Source=DSN;Initial Catalog=c:/MySoft/db/mysoft.db
