我正在开发的C＃.NET 3.5的WPF程序。它工作在Windows XP，Windows Vista和Windows 7。在新的操作系统我wantet创建Aero的玻璃的背景。因此，这是唯一的一个特别的设计。休眠后，在挂起后或更改Windows Desings一个基本的设计和回AERO所有添加的玻璃后，将显示全黑的。

I am developing a program in C# .net 3.5 wpf. It has to work on windows xp, windows vista and windows 7. On the newer operation systems I wantet to create the background in Aero Glass. So this is only a special design. After hibernate, after suspending or after changing windows Desings to a basic design and back to aero all the added glass is displayed completely black.

我通过GlassHelper类显示器玻璃（可与谷歌中找到）。

I display Glass via the GlassHelper Class (can be found with Google).

其实我看到3种方式来解决这个问题。首先是，是啊，去解决它。但我读somwhere，这是管理的code中的Windows中的一个错误，所以我别无选择，来解答它。纠正我，如果我错了。

Actually I see 3 ways to solve this problem. The first is, yea to solve it. But i read somwhere, that this is a bug in the Windows Managed Code so I have no option to sovle it. Correct me, if I am wrong.

所以，我有想法关闭窗口每次，它最小化，并完全重建，在它那用于下一次。

So I had the idea to close the window everytime, it is minimized and to rebuild completely, when it s used next time.

这工作得很好。经过冬眠的窗口仍显示黑色的，但我没有退出应用程序，我仍然可以将其最小化并再次最大化。

That works quite well. After hibernate the window is still displayed black, but i do not have to quit the application, i can still minimize it and maximize again.

现在我看到的方式：

1）我关闭窗口每次，计算机暂停，休眠或更改设计。我再次打开它的窗口，当它是保存。但是，我怎么能处理呢？

1) I close the window everytime, the computer suspends, hibernates or changes the design. And I open it the window again, when it is save. But how can I handle this?

2）我同意，该窗口将显示为黑色，直到有人最大限度地减少它。 （不是我喜欢的），但后来我得到一个新的问题：在任务栏上的按钮。 （不是托盘图标）。我需要它来进行永久展示。在WinXP我需要它来打开的窗口，最小化时。特别是在WIN7我需要它，因为我想用一些Superbar的新优势！ （在preVIEW由hoovering不会是窗口，这将是一个静态图象。）

2) I accept, that the window will be displayed in black, until someone minimizes it. (Not my favourite) But then I get a new Problem: The Button in The Taskbar. (Not the Tray Icon). I need it to be displayed permanently. On winxp i need it to open the window, when minimized. And especially on win7 I need it because I want to use some of the new Advantages of the Superbar! (the preview by hoovering will not be the window, it will be a static picture.)

谢谢大家，对我的帮助！

Thank you everyone, for helping me!

推荐答案

好了，谢谢大家！但我想我找到了我自己的解决方案！

Ok, thank you everyone! But I think I found my own solution!

我处理好消息：WM_DWMCOMPOSITIONCHANGED（0x031E）及WM_THEMECHANGED（0x031A）

I handle the Messages: WM_DWMCOMPOSITIONCHANGED (0x031E) & WM_THEMECHANGED (0x031A)

和上醒目的消息之一，我只是重新分配的玻璃或根据DwmIsCompositionEnabled（）。

and on catching one of those messages I simply assign the glass again or a new background depending on DwmIsCompositionEnabled().

其实我也有类似下面的内容：

Actually I have something similar to the following:

const int WM_THEMECHANGED = 0x031A;
const int WM_DWMCOMPOSITIONCHANGED = 0x031E;

private static void ApplyTheme(IntPtr hwnd)
{
    if (DwmIsCompositionEnabled())
    {
        HwndSource.FromHwnd(hwnd).CompositionTarget.BackgroundColor = Colors.Transparent;
        MARGINS margins = new MARGINS(new Thickness(-1));
        DwmExtendFrameIntoClientArea(hwnd, ref margins);
    }
    else
    {
        HwndSource.FromHwnd(hwnd).CompositionTarget.BackgroundColor = SystemColors.ActiveCaptionBrush.Color;
    }
}

private static IntPtr WndProc(IntPtr hwnd, int msg, IntPtr wParam, IntPtr lParam, ref bool handled)
{
    if (msg == WM_THEMECHANGED)
    {
        ApplyTheme(hwnd);
    }
    if (msg == WM_DWMCOMPOSITIONCHANGED)
    {
        ApplyTheme(hwnd);
    }
    return IntPtr.Zero;
}

我得到的HWND。

I get the hwnd.

我把它挂。

HwndSource.FromHwnd(hwnd).AddHook(new HwndSourceHook(WndProc));

我做WPF窗口背景透明的，因为后来，在WndProc的功能，我将只能够访问我的HWND背景的（Win32）。

I make the WPF Window Background transparent, because later, in the WndProc function I will only be able to access my hwnd Background (Win32).

window.Background = Brushes.Transparent;

而现在我只需要指定样式的第一次：

And now I only have to assign the style for the first time:

ApplyTheme(hwnd);

这就是它！作品完美的我（赢64家premium）后，我禁用或启用航空，不同的航空和非航空风格或休眠状态之间进行切换，因此正是，我一直在寻找。谢谢你，为你的伟大的想法！

Thats it! Works perfectly for me (Win 64 Home Premium) after I disable or enable aero, switch between different aero or non-aero styles or hibernate, so it is exactly, what I was looking for. Thank you, for your great ideas!
