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!

Besure third parameter is set to ZERO
RegQueryValueEx ( C_ULONG, -- this has to be a handle to a key
C_POINTER, -- zero terminated string name of value
C_POINTER, -- always set to zero
C_POINTER, -- pointer buffer for a variable type
C_POINTER, -- pointer to buffer to receive data
C_POINTER )-- pointer to a variable buffer that
-- contains the sizeof above buffer in bytes.

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