LKBEN11641: How to find windows command line variables to use in a qt c++ application?
Symptom
You need to resolve some environment variable from windows to use in your c++ application.
Cause
This is by design.
Solution
Sometimes you need to know the path to an environment variable like %programdata% to use in your Qt application. To resolve these variables in code, you can use different methods. One of the is via the getenv() function.
Here an example to resolve $env:ProgramData from the powershell or %programdata% from the cmd:
QString script = getenv("Programdata");
As an alternative you can use the qEnvironmentVariable() fucntion or make use of the QStandardPaths::standardLocations() function.
Have fun.
