'Globally define a conditional'?

[TimeOut]

Hi all

I was a reading a MIDI Visaul C++ book and in one line it read:

'Globally define the conditional _MIDIIN'

Anyone know how I would globally define a conditional?

Would be most grateful for any advice given. Thanks alot.

Hi

I would put:

#ifndef _MIDIIN
#define _MIDIIN

at the top of my header file or source file.

Hope that works.

Thanks alot.
