That would be ERROR_CALL_NOT_IMPLEMENTED "This function is not supported
on this system."

You are calling some NT-only API. Have you built a Unicode build, by any
chance? Those don't work on Win9x systems.

Debug under Win98, find out.

With sufficient thrust, pigs fly just fine. However, this is not
necessarily a good idea. It is hard to be sure where they are going to
land, and it could be dangerous sitting under them as they fly
overhead. -- RFC 1925

In most cases MSLU should bridge the UNICODE code to the
ANSI OS functions in Win9x. You need to link against unicows.lib
before any other system importlibs, but after all user libs. You may
need to ignore all default libs and introduce them separately.

Thank you for your instant reply.
It really makes me feel doubtful that it works on Win9x originally.
But after I added some picture drawing API, it fails.
Then I delete the api,
But still it won't work for me.:(
I really build the project with unicode support.
I'll try delete the support later.

And thanks again for your reply.

Thank you for your instant reply.

I tried as you said.
But unfortunately, it failed to work.
I got the error code 0x80070078 once again.
Thanks again for your reply.

You can try using ANSI builds instead of UNICODE... Still,
for the majority of Win32 API functions MSLU works alright.
BTW, don't forget to distribute unicows.dll, otherwise it's not
going to work - it'll silently fail. Just put it alongside your
executable.

Thank you for your kind help.

I did as you said.

And I found another problem when registering my dll with regsvr32.

The error code is 0x00000485, ERROR_DLL_NOT_FOUND.

And I checked the error with dependency walker.
The following dll missed:

APPHELP.DLL AUTHZ.DLL DNSAPI.DLL NTDSAPI.DLL NTLANMAN.DLL

But I didn't use any network related api.
How can I remove the dependency of my dll on these dll?

Thanks very much again for your reply.

What exactly does your DLL do? There are a bunch of NT-
specific DLLs listed in your post. Note that as of VC 7.0
Microsoft no longer maintains compilation compatibility with
Win9x, so it's up to you to ensure it. You may have to discard
ATL and MFC in order to achieve that...

Thank you for your reply.
It's a web based mp3 recorder.:)
Exactly, a MessageBox's problem:(
And now it's been solved.:)

Really appreciate you for your help.
