确定 C++ 应用程序是否作为 UWP 应用程序运行，具有旧版支持 [英] Determine if C++ application is running as a UWP app, with legacy support

问题描述

我的第一个想法是使用 GetPackageFamilyName() 并寻找 ERROR_SUCCESS 与 APPMODEL_ERROR_NO_PACKAGE.

My first thought was to use GetPackageFamilyName() and look for ERROR_SUCCESS vs APPMODEL_ERROR_NO_PACKAGE.

但是，我需要支持 Windows 7，这使得 GetPackageFamilyName() 无法使用.

But, I need to support Windows 7, which makes GetPackageFamilyName() unusable.

有没有像样的替代方法?也许注册表中有任何东西?

Is there a decent alternative method? Anything in the Registry, perhaps?

推荐答案

使用 GetProcAddress() 在运行时动态加载 GetPackageFamilyName()，例如:

Use GetProcAddress() to load GetPackageFamilyName() dynamically at runtime, eg:

typedef LONG WINAPI (*LPFN_GPFN)(HANDLE, UINT32*, PWSTR);
bool bIsUWP = false;

LPFN_GPFN lpGetPackageFamilyName = (LPFN_GPFN) GetProcAddress(GetModuleHandle(TEXT("kernel32")), "GetPackageFamilyName");
if (lpGetPackageFamilyName)
{
    UINT32 size = 0;
    if (lpGetPackageFamilyName(GetCurrentProcess(), &size, NULL) == ERROR_INSUFFICIENT_BUFFER)
        bIsUWP = true;
}

if (bIsUWP)
{
    //...
}
else
{
    //...
}

或者，考虑使用 GetCurentPackage...() 函数之一 (GetCurrentPackageFamilyName(), GetCurrentPackageId(), GetCurrentPackageInfo(), etc) 而不是使用 GetPackageFamilyName() 带有 HANDLE 到调用进程.

Alternatively, consider using one of the GetCurentPackage...() functions (GetCurrentPackageFamilyName(), GetCurrentPackageId(), GetCurrentPackageInfo(), etc) instead of using GetPackageFamilyName() with a HANDLE to the calling process.
