What is the best way to create a form similar to the VS binary file view?

Thanks for the suggestion its just what I need but I struggled to pass data to the control.

The solution required the use of a "VariantWrapper".

I created a c# form test project, added the HexEdit control and 1 button that loaded the control with data in the click event.

I needed the following class variables:

public partial class Form1 : Form
{
    // to wrap the array that I am going to pass
    System.Runtime.InteropServices.VariantWrapper var;
    // the actual array that I will pass
    Array t;
    // an object to pass to the SetData method
    object o;
    .
    .

In the form constructor:

public Form1()
{
    InitializeComponent();
    // create an array of 50 bytes to send to the control
    t = Array.CreateInstance( typeof(byte), 50 );

Then in my click event:

private void button1_Click(object sender, EventArgs e)
{
    // load the array with some data
    for (int i = t.GetLowerBound(0); i <= t.GetUpperBound(0); i++)
        t.SetValue((byte)(i + 0x30), i);

    // Create a wrapper 'var' around t
    var = new System.Runtime.InteropServices.VariantWrapper(t);
    // copy var into an object and pass to the control
    o = var;
    axHexEdit1.SetData(ref o, 0);

}

This got the control working but I ran into another problem - System.Runtime.InteropServices.SEHException

The solution for that is here:
