[C++/Cx] How can I get the AsyncOperationWithProgress progress?

Windows Runtime provides the HttpClient class along with async APIs. For example, you can send a GET request through the GetAsync(Uri) method. GetAsync() method is an awaitable API so that it returns IAsyncOperationWithProgress<HttpResponseMessage, HttpProgress>^. You will get the HttpResponseMessage by specifying the IAsyncOperationWithProgress to Concurrency::create_task(). However, how can I get the progress? There's no direct … Continue reading [C++/Cx] How can I get the AsyncOperationWithProgress progress?

Generating assembly output from msvc and CMake

Sometimes it's needed or you may require to see the assembly output listing of a C++ snippet code just for the testing purpose. Testing yourself with Jason Turner's session might be the example. If you're using a msvc with Windows environment, then it's quite easy by running the simple command line argument: Let's say we have … Continue reading Generating assembly output from msvc and CMake

Demo app shows std::stable_partition and std::rotate works

https://channel9.msdn.com/Events/GoingNative/2013/Cpp-Seasoning From the beginning of Sean Parent's great C++ talk, he represented two std algorithms people may not be familiar of. It's 'std::stable_partition' and 'std::rotate'. I made a small demo application shows how the two algorithms works. It's Qt5 based application so that you can freely compile and run from Windows, mac or Linux. Grab … Continue reading Demo app shows std::stable_partition and std::rotate works

CppRest SDK(Casablanca) + static CRT link = caution! (might cause debug heap assert)

The C++ REST SDK(Casablanca) is currently only available to link dynamically(DLL) unless you build the library on your own. Here is the link describing the steps to link static to your application by downloading the source code and building it so. If you're using the cpprest sdk and unfortunately encountered the following debug heap assert, you probably made mismatch configuration for … Continue reading CppRest SDK(Casablanca) + static CRT link = caution!
