Solution 2

The error message does explain the problem pretty clearly: you haven't created a connection, or your connection string is wrong, or you haven't opened the connect before you try to use it.

But...from just one line of code we can't even start to tell which.
So look at you code, find where the Connection instance is created, and see what happens to it from there. We can't do that for you: we can't see your screen, access your HDD, or read your mind...

my connection is true ! and i open that ! but ....
see :
cm.Connection.Open();
Mysp_tblFeeds_Update.ExecuteNonQuery();
cn.Close();

did you mistyped "cm" and "cn" ? or perhaps that can possibly be the problem?

goathik 25-Jun-14 9:26am

anyway, please, insert your full block of code for better analysis

Solution 3

C#

if (conn.State == ConnectionState.Open)
                    conn.Close();
                conn.Open();

Check your connection object

Solution 4

it seems you are opening some other connection. do as below

C#

Mysp_tblFeeds_Update.Connection.Open();
Mysp_tblFeeds_Update.ExecuteNonQuery();

that will make sure you are opening connection of the command
