How can I remove the selection border on a ListViewItem

Question

I'm using SetWindowTheme and SendMessage to make a .net listview look like a vista style listview, but the .net control still has a dotted selection border around the selected item:

Selected items in the explorer listview don't have that border around them. How can I remove it?

Windows Explorer:

Edit: Solution:

public static int MAKELONG(int wLow, int wHigh)
{
    int low = (int)LOWORD(wLow);
    short high = LOWORD(wHigh);
    int product = 0x00010000 * (int)high;
    int makeLong = (int)(low | product);
    return makeLong;
}

SendMessage(olv.Handle, WM_CHANGEUISTATE, Program.MAKELONG(UIS_SET, UISF_HIDEFOCUS), 0);

Telanors solution worked for me. Here's a slightly more self-contained version.

using System;
using System.Runtime.InteropServices;
using System.Windows.Forms;

public class MyListView : ListView
{
    [DllImport("user32.dll", CharSet = CharSet.Auto)]
    static extern IntPtr SendMessage(IntPtr hWnd, int Msg, int wParam, int lParam);

    private const int WM_CHANGEUISTATE = 0x127;
    private const int UIS_SET = 1;
    private const int UISF_HIDEFOCUS = 0x1;

    public MyListView()
    {
        this.View = View.Details;
        this.FullRowSelect = true;

        // removes the ugly dotted line around focused item
        SendMessage(this.Handle, WM_CHANGEUISTATE, MakeLong(UIS_SET, UISF_HIDEFOCUS), 0);
    }

    private int MakeLong(int wLow, int wHigh)
    {
        int low = (int)IntLoWord(wLow);
        short high = IntLoWord(wHigh);
        int product = 0x10000 * (int)high;
        int mkLong = (int)(low | product);
        return mkLong;
    }

    private short IntLoWord(int word)
    {
        return (short)(word & short.MaxValue);
    }
}
