1. Off-topic: Problem with a C func

I just got a book recently, the "Win32 API Bible". It has tons of stuff in it from creating windows to error and exception handling, I've even made two programs that talk to each other with Windows thingies called atoms! I'm working on a library for using the registry. It's worked well so far except for one function: RegQueryValueEx. The problem is, I give it the exact parameters as shown in the book, but it either returns ERROR_BAD_ PARAMETER or ERROR_FILE_NOT_FOUND, and I don't know why! I was hoping that maybe someone could help and show me what to pass it. P.S. I noticed that if I give it a LONG and six POINTERs, it returns ERROR_BAD_PARAMETER. But if I pass it only 5 POINTERs, it returns ERROR_SUCCESS and the area where the value data should be has nothing but garbage.

Hi, I created a set of routines for accessing the Windows Registry some time ago; you might want to take a look at it (some routines use RegQueryValueExA). It is available from my Euphoria page at http://davitf.n3.net/ , in the "Misc libraries" section. I hope it helps!

Sadly, I did set the third parameter to 0 when I coded the func.
