1, First Set FormBorderStyle = None
2,
     Import winapi Dll
    [DllImport("shell32.dll")]---May be [DllImport("user32.dll")] I forgot
    public extern static   ShowWindow(System.IntPtr handler,int showStyle);ShowStyle could be :
SW_HIDE = 0,
/// <summary>
/// Õý³£ÏÔÊ¾
/// </summary>
SW_SHOWNORMAL = 1,
/// <summary>
/// ×îÐ¡»¯
/// </summary>
SW_SHOWMINIMIZED = 2,
/// <summary>
/// ×î´ó»¯
/// </summary>
SW_SHOWMAXIMIZED = 3,
/// <summary>
/// ÏÔÊ¾£¬µ«²»¼¤»î
/// </summary>
SW_SHOWNOACTIVATE = 4,
/// <summary>
/// Õý³£ÏÔÊ¾
/// </summary>
SW_SHOW = 5,
/// <summary>
/// MINIMIZE
/// </summary>
SW_MINIMIZE = 6,
/// <summary>
/// MINIMIZE and not active
/// </summary>
SW_SHOWMINNOACTIVE = 7,
/// <summary>
/// Show normal and not active
/// </summary>
SW_SHOWNA = 8,
/// <summary>
/// restore from maximum or minimum
/// </summary>
SW_RESTORE = 9,
SW_SHOWDEFAULT = 10,
SW_MAX = 11
protected override WndProc(Message M)
{
         ....
}
恩，第二个问题可以执行，但第一个还是不能这样（补充一下,我不想要form标题隐藏，即不要Set FormBorderStyle = None）
