How to use .Net Business Connector for Dynamics Ax 4.0 within .Net

Requirement :
1) Ax 4.0 with .Net Business Connector
2) Visual Studio 2005 (preferred)

Business Connector enables third-party applications to interface with Microsoft Dynamics AX as though they were a native Microsoft Dynamics AX client. Applications built using the Microsoft .NET Framework or ASP.NET can now interface with Microsoft Dynamics AX using the .NET Business Connector. The .NET Business Connector is integrated with Enterprise Portal and Web services. You can leverage the benefits of these other applications and services by installing the .NET Business Connector.


Open your visual studio.
Click on File>New>Project. New Project window will open. Select Visual C# from Project types and Windows Application from Templates. Give a name in the Name field and click on OK button.














By default Form1 will be added to your project.
From Toolbox add a button and a textbox to the form as shown below:



















Double click on the button.
Now see the default code below:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;

namespace DotNet2Ax //your project name
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

private void button1_Click(object sender, EventArgs e)

Now add the below lines in the button1_Click method.

Microsoft.Dynamics.BusinessConnectorNet.Axapta DAX = new Microsoft.Dynamics.BusinessConnectorNet.Axapta();
Microsoft.Dynamics.BusinessConnectorNet.AxaptaRecord DAXRec;
DAX.Logon(null, null, null, null);
DAXRec = DAX.CreateAxaptaRecord("CustTable");
DAXRec.ExecuteStmt("select firstonly * from %1");
textBox1.Text = (string) DAXRec.get_Field("name");

After adding the lines it will look like:
private void button1_Click(object sender, EventArgs e)
{
Microsoft.Dynamics.BusinessConnectorNet.Axapta DAX = new Microsoft.Dynamics.BusinessConnectorNet.Axapta();
Microsoft.Dynamics.BusinessConnectorNet.AxaptaRecord DAXRec;
DAX.Logon(null, null, null, null);
DAXRec = DAX.CreateAxaptaRecord("CustTable");
DAXRec.ExecuteStmt("select firstonly * from %1");
