reg扩展名的注册文件不能有空格,否则系统会判断错误!!!

做gridview的自定义翻页按钮时,必须使用手动绑定..
public void GridView1_PageIndexChanging(object sender,gridviewPageEventargs e)
{
gridview1.pageIndex=e.NewPageIndex;//前一页就是pageindex等于pageindex-1,最后一页就是pageindex=pagecount-1
GridViewDataBind();
}
存储过程在OleDb里的指令是CommandType.Text,在SqlCommand里是COmmandType.StoreProcedure;
SqlCommand scmd=new sqlcommand();
cmd.CommandText="ReadCustomerAndOrders";//存储过程
SqlDataReader rd=scmd.ExecuteReader();
if(rd.read())
//...read result set
reader.NextResult();
private static void ReadOrderData(string connectionString)
{
string queryString =
"SELECT OrderID, CustomerID FROM dbo.Orders;";
using (SqlConnection connection = new SqlConnection( //这时候用using..
connectionString))
{
SqlCommand command = new SqlCommand(
queryString, connection);
connection.Open();
SqlDataReader reader = command.ExecuteReader();
try
{
while (reader.Read())
{
Console.WriteLine(String.Format("{0}, {1}",
reader[0], reader[1]));
}
}
finally
{
// Always call Close when done reading.
reader.Close();
}
}
}
