在WPF应用程序中禁用Aero Peek

| 我想在WPF应用程序中禁用Aero Peek(当用户将鼠标置于“显示桌面”按钮上时,我的应用程序必须可见)。我使用以下PInvoke签名:
[Flags]
public enum DwmWindowAttribute : uint
{
    DWMWA_NCRENDERING_ENABLED = 1,
    DWMWA_NCRENDERING_POLICY,
    DWMWA_TRANSITIONS_FORCEDISABLED,
    DWMWA_ALLOW_NCPAINT,
    DWMWA_CAPTION_BUTTON_BOUNDS,
    DWMWA_NONCLIENT_RTL_LAYOUT,
    DWMWA_FORCE_ICONIC_REPRESENTATION,
    DWMWA_FLIP3D_POLICY,
    DWMWA_EXTENDED_FRAME_BOUNDS,
    DWMWA_HAS_ICONIC_BITMAP,
    DWMWA_DISALLOW_PEEK,
    DWMWA_EXCLUDED_FROM_PEEK,
    DWMWA_LAST
}

[Flags]
public enum DWMNCRenderingPolicy : uint
{
    UseWindowStyle,
    Disabled,
    Enabled,
    Last
}

[DllImport(\"dwmapi.dll\", PreserveSig=false)]
[return: MarshalAs(UnmanagedType.Bool)]
public static extern bool DwmIsCompositionEnabled();

[DllImport(\"dwmapi.dll\", PreserveSig=false)]
public static extern Int32 DwmSetWindowAttribute(IntPtr hwnd,
                                                 DwmWindowAttribute dwmAttribute,
                                                 IntPtr pvAttribute,
                                                 uint cbAttribute);
和这种用法:
    var helper = new WindowInteropHelper(this);
    helper.EnsureHandle();

    if (API.DwmIsCompositionEnabled())
    {
        var status = Marshal.AllocCoTaskMem(sizeof(uint));
        Marshal.Copy(new[] {(int) API.DWMNCRenderingPolicy.Enabled}, 0, status, 1);
        API.DwmSetWindowAttribute(helper.Handle,
                                  API.DwmWindowAttribute.DWMWA_EXCLUDED_FROM_PEEK,
                                  status,
                                  sizeof (uint));
    }
在我的64位系统(Windows 7 Professional)中,仅当我运行64位应用程序时,它才有效。如果我以WOW64模式运行32位应用程序,则会收到异常: \“对PInvoke函数\'XXX :: DwmSetWindowAttribute \的调用已使堆栈不平衡。这可能是因为托管的PInvoke签名与非托管的目标签名不匹配。请检查PInvoke签名的调用约定和参数是否与目标匹配非托管签名。\“ 你怎么看待这件事?解决办法是什么?

[DllImport(\"dwmapi.dll\", PreserveSig = true)]
public static extern int DwmSetWindowAttribute(IntPtr hwnd,
                                               DwmWindowAttribute dwmAttribute,
                                               IntPtr pvAttribute,
                                               uint cbAttribute);
和用法:
if (API.DwmIsCompositionEnabled())
{
    var status = Marshal.AllocHGlobal(sizeof(int));
    Marshal.WriteInt32(status, 1); // true
    API.DwmSetWindowAttribute(helper.Handle,
                              API.DwmWindowAttribute.DWMWA_EXCLUDED_FROM_PEEK,
                              status,
                              sizeof(int));
}
