因毕业设计问各位高手们连接SQL的问题,小弟新手,谢谢了!
我想问一下,我不想在Default.aspx用
<%@ Import Namespace= "System.Data " %>
<%@ Import Namespace= "System.Data.Sqlclient " %>
这种方法连入SQL,我想用在Default.aspx.vb里面用VB.NET的语言写,请问应该怎样写啊?谢谢了!
[解决办法]
可以啊.改成vb的就可以了. SqlConnection conn =null;SqlDataAdapter dapt = null;DataSet ds = new DataSet();string strConnectionString = "Data Source=.;initial catalog=数据库;uid=sa;pwd=xxx ";string strSQL = "SELECT 字段 from 表 "try{conn = new SqlConnection(strConnectionString);conn.Open();dapt = new SqlDataAdapter(strSQL,conn);dapt.Fill(ds, "table1 ");DataTable dt = ds.Tabls[0];if(dt.Rows.Count > 0){ this.Text1.Text = dt.Rows[0][ "字段 "].ToString();}}catch(System.Exception e){ this.Text1.Text = "错误 "+e.Message;}finally{if(conn!=null)conn.Dispose();if(dapt!=null)dapt.Dispose();}

Dim student_id As String = Request.Cookies( "userInf ").Values( "userID ")
Dim mySqlConnection As String
mySqlConnection = "Data Source=localhost;initial catalog=user;user id=lgw;password=lgw;connect timeout=30 "
Dim connuser As New Data.SqlClient.SqlConnection(mySqlConnection)
conn.Open()
Dim strSql As String = "select * from users where id= " & student_id
