Avoid WMI (slow and not installed by default)
Use Kernel and Shell apis

See rather the Microsoft sample.
16 years old... (beginner code for a so simple api, posted 10000 times on BBS & Usenet...)

Never use System()
It's prohibited in Production environment, in particular on Windows...

On Windows, you don't need sockets; just use COM (10 lines of code)

This "code" has no sense at all (case, case, case... horrible !!!!)
It's done in 1 line of code with Win32 api (VK)

And what's the problem with that ?!
It's by far the best compiler/debugger on the market.
All Big Companies have VS 2008 Enterprise licences and nothing else. It's just unbeatable nowadays..

You're a complete noob. (Probably very , very young.. )
Newsgroups (Usenet) is by far the best place on the Web, for more than 20 years !
There are the greatest Win32 gurus, MS consultants, some of...

The Petzold is, by far, the best book and the C code is of course compatible with XP and Vista !
And for Advanced win32, see old Win32 group http://tinyurl.com/cmhb5g
(with Windows source code...)...

Why don't you look at MSDN samples ?!
(plenty of samples in C,C++ for each api...)

On Windows, simply use the Chart control.

It has no sense at all to disable UNICODE !!
It's the standard !
Windows itself is UNICODE (see Kernel or User source code..)

No sense.
GIF is binary.

On Windows, just use Win32 api (Net, 1 line of code)

This code is wrong (no recursive, no reparse points, etc)
See the official MS sample (SDK)

Everything about Win32 api has been answered for 20 years on Win32 api group
Everything about Excel has been answered for 20 years on Excel group
etc...

Why reposting questions answered...

Yes, there are always Win32 apis for eveything
See on Win32 api group (news://nntp.aioe.org/comp.os.ms-windows.programmer.win32)

Just use Win32 api
See on Win32 api group (news://nntp.aioe.org/comp.os.ms-windows.programmer.win32) where it's a classic question.

What a horror !!!
It is not a keylogger at all !
Ask on Professional Win32 api Group (news://nntp.aioe.org/comp.os.ms-windows.programmer.win32)
to learn how to make real keyloggers..

Never use system()
Just use OS api, win32 api if Windows (SH)

If its' on Windows, just use win32 api
(1 line of code..)

Paths must never be hard coded. You must get them from Shell.

The official way is with Win32 COM
(never use keybd_event, not professonal at all...)

In Win32, nothing is needed.
All formats are native.

SDL is totally useless, as MP3 is native in Win32.
See MSDN samples to play MP3.
(3 lines of code with mci...)
