Complex Registry string?
Hi,

i am trying to add a registry string. I don't mean to create a new key with an value, but reading out an existing and updating it's value.

The key value holds several path seperated with an ";" and I simply want to check, if my path is already in it and if not readign the current value and adding my path, writting the complete value back. Also I need to delete my path out of the key, if I uninstall the program. However it could be that another path was added, so I cannot simply delete the last characters. I need to know the exact position to get it out.

Found none string manipulation for this operation in the documentation. How would it be the best to handle this problem?

Thx,
Phobeus

This example should answer all of your questions:
http://nsis.sourceforge.net/archive/....php?pageid=91

There are two functions in there. One to add a directory to the path and one to remove it. It works on both Windows NT and 9x. If it's not the path you want to change it's still a good example of how to process the kind of string you wish to process.
