I am busy with a windows phone 8 application that i want to interact with my desktop. 我正忙于要与桌面交互的Windows Phone 8应用程序。

I have an SelfHosted WebApi that my phone posts data too. 我有一个SelfHosted WebApi，我的手机也发布了数据。 Now everything works fine if i run the service from Visual Studio. 现在，如果我从Visual Studio运行服务，一切都会正常。 I can interact with the Desktop, but as soon as I install the service (using WIX) i cant interact with the desktop. 我可以与桌面进行交互，但是一旦安装了该服务（使用WIX），我便无法与桌面进行交互。

The Service settings: I'm logged on as Local System and "Allow service to interact with desktop" is checked. 服务设置：我以本地系统身份登录，并选中了“允许服务与桌面交互”。

From what i can see is, i can post data to the service, but as soon as i run the following line. 从我所看到的是，我可以将数据发布到该服务，但是只要运行以下行即可。

System.Windows.Forms.Cursor.Position = new System.Drawing.Point(cursorX + deltaX, cursorY + deltaY); System.Windows.Forms.Cursor.Position =新的System.Drawing.Point（cursorX + deltaX，cursorY + deltaY）;

It does not do anything. 它什么也没做。

Any help will be much appreciated. 任何帮助都感激不尽。

If you start a service with "Allow service to interact with desktop" doesn't mean that you can do all "usual" screen activities. 如果您使用“允许服务与桌面交互”启动服务，并不意味着您可以执行所有“常规”屏幕活动。 Actually you are limited to a very small set of functions which are allowed. 实际上，您只能使用很少的一组功能。 Please see https://msdn.microsoft.com/en-us/library/windows/desktop/ms683502.aspx for details. 有关详细信息，请参见https://msdn.microsoft.com/zh-cn/library/windows/desktop/ms683502.aspx 。

So I ended up making a system tray application. 因此，我最终制作了系统任务栏应用程序。

Windows services (from Windows Vista onwards) run in a isolated session (session 0). Windows服务（从Windows Vista开始）在隔离的会话（会话0）中运行。 This prevents any interaction with the desktop, even though the "interact with desktop" option is checked. 即使选中了“与桌面交互”选项，这也可以防止与桌面进行任何交互。 I can't see any way around this limitation 我看不到这种限制的任何方式
