[Win32] [C ++]检查Win32应用程序的商店许可证 [英] [Win32][C++] Checking Store License of a Win32 Application
问题描述
我正在尝试检查我的应用中的许可证是否有效。该应用程序是一个简单的win32程序，使用visual studio 2017开发。我的问题是，许可证检查总是返回true（激活），即使它不应该（产品从未上传到
商店）。
你能帮助我并告诉我我做错了吗？

您好，
isActive属性用于标识应用程序的状态。如果你已经免费从商店下载了应用程序，那么它将永远是真的。如果你。如果您已从商店购买该应用程序，它也将返回true。有一个条件，
isActive将为您下载试用版的应用程序而返回false，当试用版过期时，isActive将返回false。如果试用版没有过期，isActive将返回true，您需要检查IsTrial属性。
现在的问题是，你如何获得应用程序？如果您免费下载或购买它或者您使用的是试用版，isActive将始终返回true。
祝您好运，

Hi,
I'm trying to check if the license is active in my app. The app is a plain win32 program that is developed with visual studio 2017. My problem is, that the license check always returns true (activated) even if it should not (product was never uploaded to the store).
Could you help me and tell me what I'm doing wrong?

}Hi,
The isActive propertyis used to identify the status of the app. If you have downloaded the App form the Store for free, then it will is always true. If you. If you have purchased the app from the Store, it will also return true. There is one condition that isActive will retrun false that you download the app for a trial version, and when the trial version expires, isActive will retrun false. If the trial version doesn't expire, isActive will return true and you will need to check the IsTrial property.
Now the question is that, how you get the app? If you download it for free or purchase it or you are using a trial version, isActive will always return true.
Best regards,
Roy
