的Windows Phone 8：访问UI调度中的C ++代码 [英] Windows Phone 8: access UI Dispatcher in C++ code

问题描述

我的工作，使用混合C＃的UI和C ++为底层的支持的Windows Phone 8应用。我有一些情况下，我需要运行UI调度线程（IE GetGeopositionAsync（））上的一些C ++代码。

I am working on an Windows Phone 8 Application that uses mixed C# for UI and C++ for the underlying backed. I have some instances where I need to run some C++ code on the UI dispatcher thread (IE GetGeopositionAsync()).

我试图从C作出回调的方法++到在UI线程中运行，然后调用C ++方法和运行C＃：

I have tried a method of making a callback from C++ to C# that runs in the UI thread and then calls a C++ method and runs:

auto window = Windows::UI::Core::CoreWindow::GetForCurrentThread();

然而，这是返回null。有没有办法为我做到这一点？

However this is returning null. Is there any way for me to accomplish this?

推荐答案

我有一个类似的问题前几天，因为它总是返回null 。我结束了使用WinRT的。根据MSDN（ 1 ，的 2 ），你应该能够在使用该WP8也是如此。

I had a similiar problem some days ago, as it has always returned null. I ended up using in WinRT. According to MSDN (1, 2) you should be able to use this in WP8 as well.
