Hi,

I am fairly new to .NET, and I am having a hard time to call a stored procedure from C# code in a windows application.
I have tested my connection (and login) several time and it is OK. If I try to do a query it works, but when I try to call a stored procedure i get the message "System Error". My code is shown below.
Any idea what could be the problem?
A million thanks!

Jenny

this.connString = ConfigurationSettings.AppSettings["connString"];
this.con = new SqlConnection(this.connString);

this.procedureName = "MyStoredProcName";
this.cmd = new SqlCommand(this.procedureName, this.con);
this.cmd.CommandType = CommandType.StoredProcedure;

SqlParameter param;
param = this.cmd.Parameters.Add("@MyParameter", SqlDbType.Int);
param.Direction = ParameterDirection.Output;


this.con.Open();
this.cmd.ExecuteNonQuery();
this.con.Close();
 
Jenny,

Wrap the ExecuteNonQuery call in a Try... Catch... block and display the Exception message (Check the docs for the syntax). This message would be more informative and
it may lead you to the solution. If not, please post the Exception message and the stored procedure script.
