No mapping exists from object type System.Web.UI.WebControls.Label to a known managed provider nativ

Posted By:      Posted Date: September 15, 2010    Points: 0   Category :ASP.Net
 
 I'm making the leap to move from vb.net to C#, and I'm getting this crazy error when I try to execute one sp, set a value, and then execute another sp based on the value.   Any suggestions??? proc_GetSectionDetails is my first stored procedure.  From that, I get a value for SectionID, and then use it for the second sp called  proc_GetSectionDetails protected void getSectionContent() { SqlConnection conn = default(SqlConnection); SqlCommand comm = default(SqlCommand); SqlDataReader reader = default(SqlDataReader); string connectionString = ConfigurationManager.ConnectionStrings["123"].ConnectionString; conn = new SqlConnection(connectionString); comm = new SqlCommand(); comm.Connection = conn; comm.CommandType = System.Data.CommandType.StoredProcedure; comm.CommandText = "proc_GetSectionDetails"; comm.Parameters.AddWithValue("SubSectionID", Request.QueryString["SubSectionID"]); conn.Open(); reader = comm.ExecuteReader(); if (reader.Read()) { lblName.Text = Convert.ToString(reader["SubSectionName"]); lblDesc.Text = Convert.ToString(reader["SubSectionDescription"]); Label SubSectionParentID = new Label();

Types in Yukon: Managed UDTs Let You Extend the SQL Server Type System

  

The next version of SQL Server, code-named "Yukon," will offer enhanced support for user-defined types (UDTs). Because UDTs can be managed by the CLR, you can represent a wide variety of data structures to create types not possible with previous versions of SQL Server. With UDTs you can more precisely control the kind of data your type accepts, resulting in better data management. This article explores UDTs in "Yukon" and covers their design and implementation.

Using IPC only channel getting Unable to cast object of type 'System.Runtime.Remoting.Identity' to

  

I have a remoting application that is using delegates to preform callbacks between processes. I found that if I don't use a TCP channel at all and only initialize an IPC channel that the callback delegates start throwing the following error after about a minute has passed.

From what little I could find on Google it seems to be a Lifetime Service management issue but all the classes that the delegates belong to return null from InitializeLifetimeService which should give the object an infinite lifetime.

With the TCP channel initialized the issue doesn't happen, but I would like it to use the IPC channel if all of the processes are on the local box.
