have a stored procedure that inserts new records into my table.  I would like to get the  @PropertyKey assigned to the record and use it in my code behind.  How do I do that?


ALTER PROCEDURE dbo.ManualOrder( 
									@LoanNumber VarChar(20),
									@ClientRefNum VarChar(50),
									@CaseNumber VarChar(50),
									@LegalDesc VarChar(Max),
									@LocTypeID Int,
									@PropTypeID Int,
									@Address VarChar(50),
									@Address2 VarChar(50),
									@City VarChar(50),
									@StateID Char (2),
									@County VarChar(50),
									@Zip Char(5),
									@ReportTypeID int,
									@ClientID int,
									@IntendedUseID int,
									@OccupancyID int,
									@LoanTypeID int,
									@RushKey Int)
AS
	BEGIN
	SET NOCOUNT ON;

	DECLARE @PropertyKey int

	INSERT INTO dbo.Property(PropAddr1,PropAddr2,PropCity,PropZip,PropCounty,ModifiedUser,CreatedUser,PropStateKey,PropTypeKey,LocationTypeKey,LegalDescription)
		SELECT        @Address, @Address2 , @City , @Zip , @County , @UserKey , @UserKey , StateKey , 
		                         @PropTypeID, @LocTypeId ,@LegalDesc
		FROM            State
		WHERE        (StateAbbr = @StateID)

			SELECT @PropertyKey = scope_identity()
END

Amend the procedure to this:
ALTER PROCEDURE dbo.ManualOrder
(
@LoanNumber VarChar(20),
@ClientRefNum VarChar(50),
@CaseNumber VarChar(50),
@LegalDesc VarChar(Max),
@LocTypeID Int,
@PropTypeID Int,
@Address VarChar(50),
@Address2 VarChar(50),
@City VarChar(50),
@StateID Char (2),
@County VarChar(50),
@Zip Char(5),
@ReportTypeID int,
@userkey int,
@ClientID int,
@IntendedUseID int,
@OccupancyID int,
@LoanTypeID int,
@RushKey Int,
@out int OUT
)
AS
      BEGIN
      SET NOCOUNT ON;

      DECLARE @PropertyKey int

      INSERT INTO dbo.Property(PropAddr1,PropAddr2,PropCity,PropZip,PropCounty,ModifiedUser,CreatedUser,PropStateKey,PropTypeKey,LocationTypeKey,LegalDescription)
            SELECT        @Address, @Address2 , @City , @Zip , @County , @UserKey , @UserKey , StateKey ,
                                     @PropTypeID, @LocTypeId ,@LegalDesc
            FROM            State
            WHERE        (StateAbbr = @StateID)

                  SELECT @PropertyKey = scope_identity()
                  set @out = @PropertyKey
                  RETURN @out
END

Then when you call the procedure from your program you just specify another parameter in its execution e.g.

declare @localvariable int
exec ManualOrder @param1,@param2,.................................,@out = @localvariable OUTPUT

I'm not sure, but I think you're asking how to execute a stored procedure from the VB .NET code-behind. Here is an article that can lead you to the correct method:
http://support.microsoft.com/kb/306574

This one might be a bit more helpful for getting return values:

I have it in C#, but this works :

        protected void btnUpdate_Click(object sender, EventArgs e)
        {
            string connectionString = ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString;
            using (var conn = new SqlConnection(connectionString))
            using (var command = new SqlCommand("Your_Stored_Procedure", conn) { CommandType = CommandType.StoredProcedure })
            {
                SqlParameter paramReturnValue = new SqlParameter();
                paramReturnValue.ParameterName = "@RETURN_VALUE";
                paramReturnValue.SqlDbType = SqlDbType.Int;
                paramReturnValue.Direction = ParameterDirection.ReturnValue;
                command.Parameters.Add(paramReturnValue);

                conn.Open();
                command.ExecuteNonQuery();
                conn.Close();

                int returnValue = (int)command.Parameters["@RETURN_VALUE"].Value;
                ...........

I can't see where you have added a variable to accept the parameter return value?
