As you may already know Metro doesn’t support named pipes. I ended up using TcpBinding for full duplex connection. This post describes what functionality is supported. Sample of my … Read more
The proper way to do this is like this: LIBS += -L/path/to -lpsapi This way it will work on all platforms supported by Qt. The idea is that you have to separate the directory from the library name (without the extension and without any ‘lib’ prefix). Of course, if you are including a Windows specific … Read more
I recommend selecting that option and thereby removing the path length limit. It will potentially save you time in future on debugging an avoidable issue. Here is an anecdote of how I came to know about it: During the compilation of my program (C# code on a Windows machine), I started getting the following error: … Read more
Copy and pasted from the Emacs FAQ, http://www.gnu.org/software/emacs/windows/: Where do I put my init file?

One possible way is to use the Visual Studio tool Spy++. Give this a try: Run the tool (for me, it’s at C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\Common7\Tools\spyxx_amd64.exe or you can download it). Note: there is spyxx.exe (32-bit version) and spyxx_amd64.exe (64-bit version) – if you don’t see anything in 64-bit use the 32-bit version (ie.catches … Read more
