我目前正在开发一个跨平台的C++ SDK,我必须将断言处理程序移植到WinRT.该过程的一部分是显示消息框,等待用户输入并在用户选择"调试"时触发断点.

我已经有一个消息框出现,但我找不到等待消息框出现的方法而不离开当前执行点.

到目前为止,这是我的代码.

// Create the message dialog factory

Microsoft::WRL::ComPtr<ABI::Windows::UI::Popups::IMessageDialogFactory> messageDialogFactory;
Microsoft::WRL::Wrappers::HStringReference messageDialogFactoryId(RuntimeClass_Windows_UI_Popups_MessageDialog);

Windows::Foundation::GetActivationFactory(messageDialogFactoryId.Get(), messageDialogFactory.GetAddressOf() );

// Setup the used strings

Microsoft::WRL::Wrappers::HString message;
Microsoft::WRL::Wrappers::HString title;
Microsoft::WRL::Wrappers::HString labelDebug;
Microsoft::WRL::Wrappers::HString labelIgnore;
Microsoft::WRL::Wrappers::HString labelExit;

message.Set( L"Test" );
title.Set( L"Assertion triggered" );
labelDebug.Set(L"Debug");
labelIgnore.Set(L"Ignore");
labelExit.Set(L"Exit");

// Create the dialog object

Microsoft::WRL::ComPtr<ABI::Windows::UI::Popups::IMessageDialog> messageDialog;
Microsoft::WRL::ComPtr<ABI::Windows::Foundation::Collections::IVector<ABI::Windows::UI::Popups::IUICommand*>> messageDialogCommands;

messageDialogFactory->CreateWithTitle( message.Get(), title.Get(), messageDialog.GetAddressOf() );
messageDialog->get_Commands(messageDialogCommands.GetAddressOf());

// Attach commands

Microsoft::WRL::ComPtr<ABI::Windows::UI::Popups::IUICommandFactory> commandFactory; 
Microsoft::WRL::Wrappers::HStringReference commandFactoryId(RuntimeClass_Windows_UI_Popups_UICommand);

Windows::Foundation::GetActivationFactory(commandFactoryId.Get(), commandFactory.GetAddressOf() );

CInvokeHandler commandListener;
commandFactory->CreateWithHandler(labelDebug.Get(), &commandListener, commandListener.m_DebugCmd.GetAddressOf() );
commandFactory->CreateWithHandler(labelIgnore.Get(), &commandListener, commandListener.m_IgnoreCmd.GetAddressOf() );
commandFactory->CreateWithHandler(labelExit.Get(), …
