UNRAR.dll problems

[xandaz]

    Hey guys. here I am again. Thanks in advance for listening. I'm working on an app to find Password encrypted RAR files. The algoritm works fine but i'm having trouble comunicating with the thread while processing UCM_NEEDPASSWORDW. How do I do that? I've looking into PostThreadMessage and WaitForSingleObject functions but nothing seems to work.
    i hope i have i provided you with wnought information so you can give me a lil push.
    Ty guys
