How to submit a message into Message Queue?

B

Bishoy George

I have an application that get data and write xml file from this data.
The application should put the data as a message in the Message Queuing.
Every time I encounter an error saying: "The queue does not exist or you do
not have sufficient permissions to perform the operation".

This is designer code:
---------------------

namespace ReceiveOrder
{
partial class ReceiveOrder
{
/// <summary>
/// Required designer variable.
/// </summary>
private System.ComponentModel.IContainer components = null;

/// <summary>
/// Clean up any resources being used.
/// </summary>
/// <param name="disposing">true if managed resources should be
disposed; otherwise, false.</param>
protected override void Dispose(bool disposing)
{
if (disposing && (components != null))
{
components.Dispose();
}
base.Dispose(disposing);
}

Could a lot of things regarding permissions. Here is
a code sample on it that might be useful:

I've mapped the database to .NET class properties and methods to
implement an multi-layered object oriented environment for your
data access layer. Thus, you should rarely ever have to type the words
SqlCommand, SqlDataAdapter, or SqlConnection again.
