In the application, there is an MFC project and a Windows Runtime Component (Universal Windows) project, see my previous question (https://learn.microsoft.com/en-us/answers/questions/2105663/issues-with-requestpurchaseasync-in-mfc-c-applicat?comment=question#comment-1826305). Now, there is a new method in Class1 to check if User Has Subscription on addons, implemented as follows:
bool Class1::CheckIfUserHasSubscription()
{
Windows::Services::Store::StoreContext^ storeContext;
storeContext = StoreContext::GetDefault();
create_task(storeContext->GetAppLicenseAsync()).then([this](StoreAppLicense^ license)
{
auto addOnLicenses = license->AddOnLicenses;
for (const auto& addOnLicense : addOnLicenses)
{
if (addOnLicense->Value->IsActive)
return true;
}
}, task_continuation_context::get_current_winrt_context());
return false;
}
After using the RequestPurchaseAsync method to "purchase" a license, the CheckIfUserHasSubscription() method is called. Despite successfully purchasing, the method returns false. It appears that the loop "for (const auto& addOnLicense : addOnLicenses)" is not executed and the check in the loop is not performed. What could be the mistake? Thank you.

IInitializeWithWindow is not used to specific hwnd.
See the sample I provided:

Thank you very much for your response. The following is my code after adding "IInitializeWithWindow".
bool WindowsRuntimeComponent1::Class1::CheckIfUserHasSubscription()
{
Windows::Services::Store::StoreContext^ storeContext;
storeContext = StoreContext::GetDefault();
HWND hwnd = GetActiveWindow();
IInitializeWithWindow* initWindow = nullptr;
HRESULT hr = reinterpret_cast<IUnknown*>(storeContext)->QueryInterface(IID_PPV_ARGS(&initWindow));
if (SUCCEEDED(hr))
{
initWindow->Initialize(hwnd);
create_task(storeContext->GetAppLicenseAsync()).then([this](StoreAppLicense^ license)
{
auto addOnLicenses = license->AddOnLicenses;
for (const auto& addOnLicense : addOnLicenses)
{
if (addOnLicense->Value->IsActive)
return true;
}
}, task_continuation_context::get_current_winrt_context());
initWindow->Release();
}
return false;
}
The method still return "false". Do I miss something? Again, thank you very much.
Hi,
Have you checked if addOnLicense->Value->IsActive value is true?
create_task(...).then(...) is an asynchronous operation and does not block the function return false
You can use get to wait for the result:
bool WindowsRuntimeComponent1::Class1::CheckIfUserHasSubscription(){
......
auto taskResult = create_task (
......
if (addOnLicense->Value->IsActive)
return true;
else
return false;
}, task_continuation_context::get_current_winrt_context ());
initWindow->Release();
return taskResult.get ();
}
Best regards,

Thank you very much for your patience, I still have a lots to learn about asynchronous operations. Following your instruction, I have implemented my code as follows:
It seems to me that:
(1). I never have a chance to check "if (addOnLicense->Value->IsActive)" because the calculation never enters the for loop "for (const auto& addOnLicense : addOnLicenses)" ;
(2). The method "taskResult.get()" always returns true.
Do I miss something? Again, Thank you very much for your help.
(1)You can use messagebox to check the code results.
(2)The method "taskResult.get()" always returns true.
Because
| IsActive | This property is reserved for future use, and it is not intended to be used in the current release. Currently, it always returns true. |
|---|
Thank you very much for your response. I now added two messagebox in the code, as shown below
Although I can see the first messagebox on the window, I never see the second messagebox. It appears that I have never checked "if (addOnLicense->Value->IsActive)".
Thank you very much.
Is your addon durable add-on?
It is a subscription addon.
Please try to use breakpoints, check StoreAppLicense is valid and its value. And make sure the account used to purchase the add-on and the account used for testing are the same.
And try to remove initialwindow-release. Call release function before app is closed.
My debug is not working and I can work only with release. I need fix this issue now. Thank you very much for your help.
You are welcome.
My debug is still not working. When I try to associate my App to the store I get a message "The microsoft store is experiencing network issues.".
Now I add another Messagebox in the code, see below:
I expect that the app skustroeID would be displayed in the message box. However, it is not. It appears that my method to use "GetAppLicenseAsync()" is not correct.
Thank you very much.
