I am getting the above error in my VS 2008 C# method when I try to invoke the SQL getColumnNames stored procedure from VS. This SP accepts one input parameter, the table name, and works successfully from SSMS. Currently I am selecting the AdventureWorks AddressType table for it to pull the column names from this table. I can see teh AdventureWorks table available in VS from my Server Explorer / Data Connection. And I see both the AddressType table and getColumnNames SP showing in Server Explorer.
But I am still getting this error listed above. Here is the C# code snippet I use to execute this:
public static DataTable DisplayTableColumns(string tt)
{
SqlDataReader dr = null;
string TableName = tt;
string connString = "Data Source=.;AttachDbFilename=\"C:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\DATA\AdventureWorks_Data.mdf\";Initial Catalog=AdventureWorks;Integrated Security=True;Connect Timeout=30;User Instance=False";
string errorMsg;
SqlConnection conn2 = new SqlConnection(connString);
SqlCommand cmd = conn2.CreateCommand();
try
{
cmd.CommandText = "dbo.getColumnNames";
cmd.CommandType = CommandType.StoredProcedure;
cmd.Connection = conn2;
SqlParameter parm = new SqlParameter("@TableName", SqlDbType.VarChar);
parm.Value = TableName;
parm.Direction = ParameterDirection.Input;
cmd.Parameters.Add(parm);
conn2.Open();
dr = cmd.ExecuteReader();
}
catch (Exception ex)
{
errorMsg = ex.Message;
}
And when I examine the errorMsg it says the following:

Where line 35 is
