IFW - Windows Registry

  • Hi,

    Does anyone know how to read/store a value from a Windows Registry key? And if a key has more than one value, how to read a concrete value?

    Right now am able to add keys and values to the registry as remove them when uninstalling the application, but can´t store a value. I have been searching for examples without any success. Any help would be welcome.

    Thanks in advance.

  • Hi,

    there is an example on our wiki: https://wiki.qt.io/Assigning_a_file_type_to_an_Application_on_Windows#How_to_do_it. Search for the function SetHkcrUserRegKey.

    Hope this helps!

  • Many thanks @Wieland,

    but my problem is with the installer script (sorry for not having explained before (-_-)). The application is fine according to the customer feedback.

    Am trying to check the existence of previous installations and if so, check which version is installed. For this, I have created a registry entry containing the application path and installed version, but I don´t know how to compare the current installation version with the previously installed one.

    Thanks in advance.
