How to play old Fast Tracker 2 XM files?

Hello gurus,

I'd like to know how I can programmatically play an old Fast Tracker 2 XM module? Thus, where can I find a set of source code that shows how to play these files without DLLs or LIBs...

Thanks for the help.

Best regards.

Fred.

Declare a member variable of type HACCEL

HACCEL m_hAccelerators;

Inside OnInitDialog

m_hAccelerators = ::LoadAccelerators(AfxGetResourceHandle(), MAKEINTRESOURCE(IDR_MYACCELERATORS));

now inside PreTranslateMessage function...

BOOL CAccelTestDlg::PreTranslateMessage(MSG* pMsg) 
{
	if (pMsg->message >= WM_KEYFIRST  &&  pMsg->message <= WM_KEYLAST )
	{
		return TranslateAccelerator ( m_hWnd, m_hAccelerators, pMsg );
	}
	else
		return CDialog::PreTranslateMessage(pMsg);
}

Hi again
i get so much feedback from u guys so many good advices so i decided to ask again
Something simple again.
I want to work with strings for my first time
what i have is a queue of characters and i want to copy one by one in a string. Do i loose the spaces when i copy the contex of the oueue list into a string?
Code:

#include string.h
using namespace std;

queue<char> PlainText;
string Plain_Text;

while (!PlainText.empty())
{
Plain_Text+=PlainText.front();
PlainText.pop();
}

printf ("%s", Plain_Text);

I get no output and the console crashes as well!!

i have no idea if this is any close to correct is definetly not good programming i know and i apologize that u have to see this
But do you have any advices to give
Thanks in advance

what is the error message ?
where doest it crash ?
have you used the debugger ?
have you considered using iterators ?

Thanks for the reply V2.0

i don't know exactly i compile no errors then i press run the console opens i get no output and then a meesage from microsoft "Program has encoutered a problem and needs to close send report?
i no is silly but i'm not familiar with the debuger i don't know how to use it effectively but i press debug-> go i get Unhandled exception in otinane.exe 0xC0000005:Access violation then i get a bunch of memory addresses(i think) that is no way for me to understand

I know i'm not helping here but thats all i can give u
Thanks again

set a breakpoint when you want the program to pause while executing to let you debug (F9).

then, use the Watch view to see your variables contents (or hover the variable in the code), and use the "Step-by-step" toolbar buttons to go next code line...

Thanks again V2.0

I used the debuger thanks to u i set the breakpoint where i assign my values to the string and i see the characters getting in memory one by one that's a cool tool
very helpful thanks.
I'm not sure if u read the rest of the replies i used printf("%s",Plain_Text.c_str());
and it works fine.
one more question v2.0 what are iterators? (u mentioned them in ur first reply)

Re: working with string-newbie

toxcct9-Mar-06 0:10

iterators are STL classes that allow you to iterate through the linked-lists items.

for instance :

std::string strText;
std::vector<std::string> PlainText;
std::vector<std::string>::iterator iterStrings;
 
for (iterStrings = PlainText.begin();
     iterStrings != PlainText.end();
     iterStrings++) {
    strText += *iterStrings;
}

STL containers are very powerful and can be very useful when one know how to use them.
unfortunately, they are sometimes hard to start with, and they frighten the beginners...

if you have time to learn at stl containers, it will always be a personal investment.

This will not work - std::queue doesn't have any iterators. I posted a similarly flawed example before I realized (so I deleted it) Smile | :)

Should be #include <string> not #include <string.h> - STL header files don't end in ".h". Another issue is the printf ("%s", Plain_Text);. If you must use printf it should look like this: printf ("%s", Plain_Text.c_str());. But using printf is a bad idea. Instead do this: cout << Plain_Text;. You may need to add an #include <iostream> for cout.

Hey Stephen Hewitt you are right:: printf ("%s", Plain_Text.c_str()); with include <string> works fine thanks
but cout<<plain_text gives="" error="" in="" compiling
the="" error:::
c:\documents="" and="" settings\antonis\my="" documents\parser\otinane.cpp(80)="" :="" c2679:="" binary="" '<<'="" no="" operator="" defined="" which="" takes="" a="" right-hand="" operand="" of="" type="" 'class="" std::basic_string<char,struct="" std::char_traits<char="">,class std::allocator<char> >'
(or there is no acceptable conversion)

I thought i was allowed to cout<< strings because i see it everywhere used
any ideas why i get error?

Thanks again for solving my problem

Re: working with string-newbie

Stephen Hewitt8-Mar-06 23:59

Have you included <iostream>? Get rid of any ".h" CRT headers you're including. printf isn't type safe, as you've found the hard way - God knows how much wasted time has been spent in the programming world tracking down obscure bugs caused by, for example, a mismatch in the format string and the parameters.

God u are so right again i have to loose the .h from the include
Thanks man ur the best.
I wonder why they teach us wrong things in college u should become a teacher Smile | :)

Smile | :)

thanks
so u sugest i use cout instead of prinf?

Re: working with string-newbie

Stephen Hewitt9-Mar-06 0:07

Yeah, I'd use cout instead of printf - Try as you will you won't get cout to crash as printf did. It will either work or not compile.

when you remove the .h and use the stl form,
always use using namespace std;
