用C++/WinRT制作简单的消息框

#include <winrt/Windows.Foundation.h>
#include <winrt/Windows.UI.Popups.h>

using namespace winrt;
using namespace Windows::UI::Popups;

int main()
{
    init_apartment();

    MessageDialog dialog(L"这是一个简单的消息框", L"消息框标题");
    dialog.Commands().Append(UICommand(L"确定", nullptr, 0));
    dialog.Commands().Append(UICommand(L"取消", nullptr, 1));

    IAsyncOperation<IUICommand> asyncOperation = dialog.ShowAsync();
    asyncOperation.Completed([](const auto& asyncOperation, const auto& asyncStatus)
    {
        if (asyncStatus == AsyncStatus::Completed)
        {
            IUICommand command = asyncOperation.GetResults();
            int id = command.Id();
            if (id == 0)
            {
                // 用户点击了确定按钮
            }
            else if (id == 1)
            {
                // 用户点击了取消按钮
            }
        }
    });

    return 0;
