HAPPY BITHDAY ME!!!
Oh wait.... I was counting seconds not days...

............... Ok I think the party is over by now, how about going
back to figuring out the code I sent you.

anon wrote:

Yes yes the party is sure to be over; I am to be glad helping you, specify what the code aspects are to be figured out by me, please, and what result is to be well done for?

abraker wrote:

How the code works... I sent you the file and turbo C++ for you to
figure it out, is it that hard to remember?

anon wrote:

I see, but either the code is compiled by yourself or otherwise you do try to understand somebody else's written program? This is the only question to you, for right now... I'm sure I'll be helping you.

PS I got from you the two compilers, merely the codeblock and the tc, but still can't locate the turbo one on the computer (

abraker wrote:

tc is the turbo... it is somebody else's code AND the ONLY code I
found that lets you output to speakers.

anon wrote:

Have glimpsed the code. The program principle's based on 'outportb' standard procedure calls with different parameters including wav file content. Has a special command for offsetting file from the start way down to the end of the file. Grasping me?

abraker wrote:

Ok what I need is for you to extract the code that doesn't read the
file, but the code that outputs to speakers. You get me?

anon wrote:

Ye I did the outporb procedure calls include parameters settings and merely also, the speakers output as itself. The source procedure, as it is, is represented in one of the header sheets ONLY by its declaration. The procedure definition, i.e. its body, has been pre-compiled and is represented as executable code not source, in a special linker library. Is the matter being what had I have to let you know of?

abraker wrote:

Let's simply things:
Extract the code that makes the speaker beep and send it to me. Make
sure you compile it and check if it beeps(might need to turn the
volume up). Nothing more nothing less.

anon wrote:

Don’t worry, the program examination is in progress )

I explored the prog a little. First, the outportb procedure is common used for ALL port i/o oprations. Majority of the outpotb calls provide settings, one of the calls is properly the sound playing. The wav file is being read in a string/field, and simply played then back. Btw. I tried to edit the wav file but its playability is highly sensitive even to the least editing. That means probably that one can't simply assign a character string to the field in the prog and then play it back, as the information is designed self-dependent as it has unknown internal links. I found out, for more, that the prog doesn't play out the complete wav file, it is likely to have place of the Windows 7/xp mismatch. Please master this information, and then we move forth. More questions? I am glad helping you.

abraker wrote:

Does it play it at all? Do you hear anything?

anon wrote:

I heard the whole wav sound via a standard playing program. But, the TC generated exe does play only the file start i.e. the sound before your voice. I.e. the pre- noise sound is only being played back.

Sorry, now I am a bit busy and I can't show you the file loading command right for now. We'll continue then.

What part of the code is responsible of outputting to the speakers
