请教：Sybase 16.0 数据库连接问题 。

[evan_nt]

1、在sybase 16.0数据库服务器上，C#开发的程序如何使用OLEDB 数据库方式连接 ？
具体连接字符串如下：
<add key="Conn" value="Provider = Sybase.ASEOLEDBProvider.2;Data Source =abc;Initial Catalog =abc;User ID =sa;Password =123456;Server Name=192.168.0.149;Network Protocol=Winsock;Server Port Address=5000;"/>

2、在sybase 16.0数据库服务器上，VB.net 开发的程序如何使用ODBC 数据库方式连接 ？
具体连接字符串如下：
Provider=MSDASQL.1;Persist Security Info=False;Extended Properties='DSN=abc;SRVR=SYBASE;DB=abc;UID=sa;PWD=abc'

3、在sybase 16.0数据库服务器上，PB 开发的程序如何使用transaction 数据库方式连接？
具体连接字符串如下：
DBTrans.DBMS = ProfileString(ls_CurPath + "\sjk.ini","Database","DBMS", "")
DBTrans.Database = ProfileString(ls_CurPath + "jsjk.ini","Database","DataBase", "")
DBTrans.LogID = 'sa'
DBTrans.LogPass = 'abc'
DBTrans.ServerName = ProfileString(ls_CurPath + "\sjk.ini","Database","Server", "")
DBTrans.UserID = ProfileString(ls_CurPath + "\sjk.ini","Database","UserID", " ")
DBTrans.DBPass = ProfileString(ls_CurPath + "\sjk.ini","Database","DatabasePassword", " ")
DBTrans.Lock = ProfileString(ls_CurPath + "\sjk.ini","Database","Lock", " ")
DBTrans.DbParm = ProfileString(ls_CurPath + "\sjk.ini","Database","DbParm", "")
DBTrans.AutoCommit = False
Connect using DBTrans;
使用上述链接方式时，sqlcode 返回-1
DBTrans.SQLCode = -1

以上问题，烦请高手帮忙 ， 谢谢 。
