系统托盘访问 [英] Systray Access

问题描述

有没有一种方法（在C＃）来访问系统托盘？ 我不是说做一个通知图标。 我想通过项目迭代中盘（我猜通过过程，但我不知道如何确定什么是真正的盘，什么只是一个过程），并重新present与项目的图标在我自己的用户界面。

Is there a way (in C#) to access the systray? I am not talking about making a notify icon. I want to iterate through the items in the tray (I would guess through the processes but I don't know how to determine what is actually in the tray and what is just a process) and also represent the items with their icons in my own ui.

推荐答案

如何你觉得Win32的互操作？我发现 C / Win32的code 可能做的伎俩为您服务。 （事实上​​，它看起来像一个有趣的问题，所以我可能会尝试解决它自己，只是不是现在）。

How do you feel about Win32 interop? I found C/Win32 code that might do the trick for you. (Actually, it looks like an interesting problem so I might try to tackle it myself, just not now).

魔术似乎是他得到的句柄到系统托盘的窗口：

The magic appears to be that he gets a handle to the system tray's window:

NotifyWnd = FindWindowEx(SysTray, 0, "TrayNotifyWnd", 0);

然后他就在它的消息泵挂钩：

Then he sets a hook on its message pump:

hHook=SetWindowsHookEx(WH_CALLWNDPROC,HOOKPROC(MsgProc),
         hInstance,dwExplorerThreadId);

然后消息泵挂钩回调过程中，他得到一个参考有关窗口中的一些指针数据：

Then during the message pump hook callback, he gets a reference to some pointer data about the window:

TWDataT* twd=(TWDataT*)GetWindowLong(NotifyWnd,0);

神秘，那么他的循环：

The mystery is then his loop:

      pTWIconDataT p=COMCTL32_332(twd->iconsInfo,i);

COMCTL32_332定义与GetProcAddress的，并分序数的Comctl32.dll 332 - 根据我的检查与依赖浏览器，这是的 DPA_GetPtr ，它从一个动态的指针数组中获取数据。我不熟悉，这是怎么回事幕后存在，但它似乎并没有完全出了问题。

COMCTL32_332 is defined with GetProcAddress and points to ordinal 332 of Comctl32.dll - according to my checking with Dependency Viewer, that's DPA_GetPtr, which gets data from a dynamic pointer array. I'm not familiar with what's going on behind the scenes there, but it doesn't seem entirely out of the question.

我要与这个自己打了一下，但希望这是一个好地方，让你开始。 ：）

I'm going to play with this a bit myself, but hopefully it's a good place to get you started. :)
