For example, sending a text line to a specific channel is simple enough to call through just one API - api_call("chat.postMessage", channel=channel, text=msg, attachments=attachment, as_user=True) You can also upload a file to a channel. However, when I … Continue reading How to upload a file from slack using SlackClient?
Building WinRT component with WRL(non C++/CX) and cppwinrt
The cppwinrt project focused to consume Microsoft provided OS winrt components and it doesn't support building a winrt component(yet) although they mentioned it will be supported later. Even though it's not technically supported yet, we still can create a winrt component with WRL(pure C++ and non C++/CX) and still can get some benefits from using … Continue reading Building WinRT component with WRL(non C++/CX) and cppwinrt
Beginning the coroutine with Visual Studio 2015 Update 3 Part 1
I recently started using the cppwinrt library which brought chances dealing with the new C++ standard(yet) coroutine. The cppwinrt recommends using C++ coroutines instead of PPL while handling async operations. Refer to the following github issues for more information: https://github.com/Microsoft/cppwinrt/issues/54 https://github.com/Microsoft/cppwinrt/issues/46 Although the coroutine concept itself might feel coming familiar because we're already exposed async … Continue reading Beginning the coroutine with Visual Studio 2015 Update 3 Part 1
[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.

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

How to embed the PDFjs into your C# Project
TL;DR https://github.com/pvginkel/PdfiumViewer is recommended if you're okay with just viewing PDFs. If you need more complicated features, then convert the PDF into base64 and pass it to a javascript function which decodes and call the PDFViewerApplication.open which is implemented at viewer.js However, it's really, really slow. The example source is at https://github.com/heejune/WinForm-PDFjs If you needed … Continue reading How to embed the PDFjs into your C# Project
