This won't work, the index will change as you delete keys.

The function is supposed to delete the key values, that's not what
this does.

You probably need to write some test cases...

i'm sorry for bothering you again on this topic, but it looks like your are 
the onlyone around having a Vista installation.

Can you please verify the attached tests and report the results back.

Thanks for your help

I actually have a Vista Home Basic install on a laptop that I can
check testcases on, at least for right now.  I'm thinking of going out
and getting a licensed copy of xp for it (linux isn't viable for it
because it isnt my laptop and its being used as the main pc for
business transactions, so it couldnt be used to help further wine
development either, other than running testcases on windows,
unfortunately)

Tom

P.S. Since the laptop can't be used for development, could you send a
precompiled binary, and I will test?

Hello Tom,

can you build advapi32_test.exe yourself or do you need an executable?

Thank you for offering your support

Hi Stefan,

I can't do this before Sunday or so. I'm in the UK and don't have my
laptop with me. I'll post the results as soon as I have something.

Cheers,

Paul.

the results:

registry.c:576:test_query_value_ex: type set to: 0x0022fe78
registry.c:1163: Test failed: Expected ERROR_SUCCESS, got 6
registry: 293 tests executed (0 marked as todo, 1 failure), 0 skipped.

That's because you're doing a RegSetValueA on a just-closed handle.

Cheers,

Paul.

All fine this time:

registry.c:576:test_query_value_ex: type set to: 0x0022fe78
registry: 293 tests executed (0 marked as todo, 0 failures), 0 skipped.

(Seeing this output (mentioning line 576) and comparing this to the previous 
one, it seems the type value is not so random as stated in the comments of that 
test, I'll have a look if time permits).

Cheers,

Paul.
