I have a little problem. Basically with Qt I saved an extension (example: .c--) in the registry editor with an icon with QSettings class. The only problem is that I would like to make sure that when you open this file with the extension (.c--) and it opens a software by default. I had never done this before in C ++ and after my research on the web I found nothing. So that's why I was wondering. Thank you for helping.

QSettings 
reg("HKEY_CURRENT_USER\SOFTWARE\Classes\.c--\DefaultIcon", 
QSettings::NativeFormat);
eg.setValue("Default", 
"path_to_icon");

//Code for open the .c-- extension with a program ?

c++ windows qt registry

  @Remy: To be fair to OP, Microsoft has been using the terminology of "Default Programs" rather than the correct technical term "File Association" for quite a few versions of Windows now.
