据我所知,Windows Runtime是Windows暴露API的新基础架构。我的问题很简单:如何从纯C代码中使用它?我不介意编写更多代码,我只想了解各个部分之间的链接方式。
我们以微软提供的基本示例为例:https://learn.microsoft.com/en-us/windows/apps/desktop/modernize/desktop-to-uwp-enhance。具体地说,“修改C++ Win32项目以使用Windows Runtime API”,其中有一个示例显示了如何从应用程序中显示toast通知。我该如何将该代码翻译成可用于普通的.c文件中的代码?
我在
请注意,这更像是一个学术问题。我以前已经成功地在C中使用过COM,并对此感到满意,但是对于这个问题,在网上找不到任何提及或文章。
谢谢。
编辑:现在我有一些执行成功的代码(结果HRESULT为S_OK),但是没有toast显示。有什么方法可以调试这个?到底哪里出了问题?我没有实现COM激活器,因为我有一个类似的PowerShell脚本,可以使用我用C编写的基本相同的内容。我被卡住了,也很迷失,希望有人可以帮忙。

我在
C:\Program Files (x86)\Windows Kits\10\Include\10.0.19041.0\winrt
中找到了一些头文件,例如windows.ui.notifications.h
,我认为这可能会有用,但我不知道应该如何使用其中的内容。在MSDN上,没有文章讨论纯C,只有各种托管语言和C ++的影射。请注意,这更像是一个学术问题。我以前已经成功地在C中使用过COM,并对此感到满意,但是对于这个问题,在网上找不到任何提及或文章。
