Registry Key Search
Hi all,

I was not successful in finding a function or macro that finds a registry (sub)key in/below a given key based on a partial string match. Nothing turned up in the NSIS archive and forum, not even Google was my friend this time.

An example of what I am trying to do to clarify: I am installing some software from within my NSIS installer, and need to find this software's uninstall registry key. Since the software creates a registry key containing a version numer and/or release information, the exact name of the registry key is not known, thus I want to search for the first key with a name that contains a given string.

Is there a function or macro out there I could go with or can anybody point me in the right direction? Any help greatly is appreciated.

Kind regards,

Steve

You can enum registry keys and check first part of names using StrCmp. You can find sample in the NSIS manual, 4.9.2.5 EnumRegKey

This is a first pointer, thanks. But how can I perform a partial string match _anywhere_ in the string? Is there a macro or function for that?

BTW strstr using System plug-in also works :)
