To: Tim Matthews I've looked into their docs, but I can't for the life of me figure out how to convert a string to lptstr, for example: set_key :: HKEY -> String -> String -> IO () set_key cat loc key = do foo <- okey regSetValueEx foo "foo" rEG_SZ "foo" 0 where okey = regOpenKeyEx cat loc kEY_ALL_ACCESS will give me an error about it expecting LPTSTR and not [char] for "foo", but I have no idea how to convert the c/win32 types using Haskell, and msdn docs aren't helping any... I know in Python the following works, but I don't want to use Python for this app... key = OpenKey(HKEY_CURRENT_USER, "Software\\7-Zip", 0, KEY_ALL_ACCESS) SetValueEx(key, "test", 0, REG_SZ, "foobar") CloseKey(key) but that's basically where I'm stuck at right now, I've searched but wasn't able to find one single use case of regSetValueEx in Haskell, otherwise I'd be done already... I've been stuck on this for days and it's a two-hour app... I'm ashamed. LOL. On Sun, Jul 22, 2012 at 1:44 AM, Tim Matthews wrote:

but I have no idea what to put into some of the arguments for regSetValueEx or regCreateKeyEx,

Those are just plain bindings to windows function so refer to msdn
