Remove horizontal scrollbar in a ListView

https://stackoverflow.com/a/2500089/1908746

My take:

	public const int GWL_STYLE = -16;
	public const int WS_HSCROLL = 0x00100000;
	public const int WS_VSCROLL = 0x00200000;
	[ DllImport( "user32.dll", EntryPoint = "GetWindowLong", CharSet = CharSet.Auto ) ]
	public static extern IntPtr GetWindowLong32( IntPtr hWnd, int nIndex );
	[ DllImport( "user32.dll", EntryPoint = "GetWindowLongPtr", CharSet = CharSet.Auto ) ]
	public static extern IntPtr GetWindowLongPtr64( IntPtr hWnd, int nIndex );
	[ DllImport( "user32.dll", EntryPoint = "SetWindowLong", CharSet = CharSet.Auto ) ]
	public static extern IntPtr SetWindowLongPtr32( IntPtr hWnd, int nIndex, int dwNewLong );
	[ DllImport( "user32.dll", EntryPoint = "SetWindowLongPtr", CharSet = CharSet.Auto ) ]
	public static extern IntPtr SetWindowLongPtr64( IntPtr hWnd, int nIndex, int dwNewLong );
	public static int GetWindowLong( IntPtr hWnd, int nIndex )
	{
	if( IntPtr.Size == 4 )
	{
	return (int)GetWindowLong32( hWnd, nIndex );
	}
	else
	{
	return (int)(long)GetWindowLongPtr64( hWnd, nIndex );
	}
	}
	public static int SetWindowLong( IntPtr hWnd, int nIndex, int dwNewLong )
	{
	if( IntPtr.Size == 4 )
	{
	return (int)SetWindowLongPtr32( hWnd, nIndex, dwNewLong );
	}
	else
	{
	return (int)(long)SetWindowLongPtr64( hWnd, nIndex, dwNewLong );
	}
	}
	protected override void WndProc( ref Message m )
	{
	switch( m.Msg )
	{
	case WM_NCCALCSIZE:
	{
	var style = (int)GetWindowLong( this.Handle, GWL_STYLE );
	if( ( style & WS_HSCROLL ) == WS_HSCROLL )
	{
	SetWindowLong( Handle, GWL_STYLE, style & ~WindowsNative.WS_HSCROLL );
	}
	break;
	}
	}
	base.WndProc( ref m );
	}
