Answer 1

String myConnectionString="Provider=MSDAORA.1; Data Source=openview; User ID=gdj; Password=gdjtest";

Answer 2

由于你写的太简单了,所以看不出错误来,其实错误很明显:
Line 11:  if(!IsPostBack)
Line 12:  myConnectionString="Provider=MSDAORA; Data Source=openview; User ID=gdj; Password=gdjtest";
Line 13:  myConnection = new OleDbConnection(myConnectionString);
相当于:
if(!IsPostBack)
{
     myConnectionString="Provider=MSDAORA; Data Source=openview; User ID=gdj; Password=gdjtest";
}myConnection = new OleDbConnection(myConnectionString);你在if 语句中定义的变量,出了这个范围,在用就报错.你可以根据自己的逻辑需要,来进行修改,可以把上面最后一句话拿进{}中.
