	private void cmdAdd_Click(object sender, System.EventArgs e)
		{
		
			SqlConnection oConn=new SqlConnection(System.Configuration.ConfigurationSettings.AppSettings["oConn"]);
			SqlDataAdapter da=new SqlDataAdapter("usp_insertproject", oConn);
			da.SelectCommand.CommandType=CommandType.StoredProcedure; 
			
			da.SelectCommand.Parameters.Add(new SqlParameter("@ProjectName",txtprojectname.Text));
			da.SelectCommand.Parameters.Add(new SqlParameter("@ProjectDesc",txtDescription.Text));

			SqlParameter projectid = new SqlParameter("@projectID",SqlDbType.Int); 
			projectid.Direction = ParameterDirection.Output; 
			da.SelectCommand.Parameters.Add(projectid);


			oConn.Open();
			da.SelectCommand.ExecuteNonQuery();
			oConn.Close();

			if(Exist)
			{
			Response.Write("Record is already exist");
			}
				}
	}
}

You don't define Exist anywhere.
You need an Exist boolean value declared somewhere. And then you will probably want to set it.
