The right way to set the Text property. You set a property by passing a value to a setter function. ::OutputDebugString(wostringstream.str().c_str()) Wostringstream << L"Pointer pressed at (" << point.X << L"," << point.Y << L")" << std::endl Access a property of type hstring, via a conversion operator to a standard type. public:īut, again, being aware of that detail is optional thanks to hstring's conversion operator to std::wstring_view. The property accessor Uri::Domain is of type hstring. You can make a Uri from a wide string literal. Here's a code example showing how to make a Uri from a wide string literal, from a wide string view, and from a std::wstring. public:īut hstring has conversion constructors that let you work with it without needing to be aware of it. Windows::Foundation::Uri is constructed from a winrt::hstring. Using std::wstring (and optionally winrt::hstring) with Uri winrt::hstring provides convertibility with std::wstring_view to provide the interoperability that std::basic_string_view was designed for. C++17 has string conversion utilities, and std::basic_string_view, to bridge the gaps between all of the string types. Variants exist in many libraries in addition to std::basic_string from the C++ Standard Library. If you're authoring APIs, then you're more likely to need to know about hstring. But in many cases-thanks to hstring's conversion constructors and conversion operators-you can choose whether or not to be aware of hstring in your client code. And that's the string type that Windows Runtime constructors, functions, and properties actually take and return. C++/WinRT does have a custom string type called winrt::hstring (defined in the C++/WinRT base library, which is %WindowsSdkDir%Include\\cppwinrt\winrt\base.h). With C++/WinRT, you can call Windows Runtime APIs using C++ Standard Library wide string types such as std::wstring (note: not with narrow string types such as std::string).
