Qt MSVC vs MinGW

Published on 2022-12-31 in Windows

So exciting that even after 13 years of introducing to Qt by my great teacher, Mani Monajjemi there’s still a lot to learn.

I was trying to use WinRT with Qt today and now after so long time sticking to MinGW, I’m switching to MSVC. Here are the 4 reasons

  1. MinGW is opensource but deep down if you are in Win32, their compiler always offers better API compatibility
  2. WinRT is available only on MSVC
  3. If you ever get around to some dll that simply doesn’t work with your project, it’s because MinGW and MSVC ABI are not the same. and probably that DLL was compiled by MSVC not MinGW. Same OS and still a different ABI, sounds too Windowsy to me
  4. Because you are on Windows, show some support to the closed-source community!

AHK Binding not Works on All Application

Published on 2017-08-28 in Windows

I use AutoHotkey  in almost all my application but I notice some Qt applications (Like ADS) had some difficulty interpreting the AHK keys correctly. The problem turns out to be affiliated with UAC and Admin rights rather than the Qt library. To solve the issue simply add following lines to the top of your AHK scripts that you want to be applied on the specific app.

#SingleInstance Force
SetWorkingDir %A_ScriptDir%
if not A_IsAdmin
   Run *RunAs "%A_ScriptFullPath%" ; Run Script as admin

This problem arises when you open a software instance with the admin rights while the AHK script doesn’t spawn with the same permission level. The above script simply run AHK with admin rights too so whether application is with or without admin right AHK script will always be able to set the key bindings.
