I have this big array and this big {for} loop to fill this array
the loop reads a soundfile, and writes it to the array, the sound data is simple, 3minutes of 10hz constant
so the sound data should be something that starts 0,1,2,3,4,...65534 then goes down and up and down again and again

but debuggin i found that when it gets aproximately to the 200 loop the data that reads will stay the same so it will fill the array with the same value from that point until it finishes loop. the soundfile can be changed to another music that has same format and the same happens, why?

[source lang="cpp"] D3DXVECTOR4 dd[7935489]; //the big array, it is located up in the head of the program.


//Data of sound
BYTE id[40];
unsigned int ivb;
unsigned short p1[2]; //right and left 1
unsigned short p2[2]; //right and left 2

FILE * fp;
fp = fopen("12.wav","r");

fread(id,sizeof(BYTE),40,fp);//read unessesary info of sound
fread(&ivb,sizeof(unsigned int),1,fp);// read the sized of the data
unsigned int ss= ivb/4;// calculate num of samples
unsigned int i;
for(i=0;i < (ss/2);i++)//fill part of the array with all sound data
{
fread(p1,sizeof(unsigned short),2,fp);
fread(p2,sizeof(unsigned short),2,fp);
dd=D3DXVECTOR4(float(p1[0]),float(p1[1]),float(p2[0]),float(p2[1]));
}[/source]

does it looks complex?,its simple man,if you know about how to make soundfiles, but i want to know if someone had that same problem.
with just that code and a soundfile,16 bits 2channels 44100samples/second, you can try it yourself and see.

and yes i just wasted like a day to get to this. I created code that was based on that array so i had to recheck it, it took me time...like a day

well the variables are initialized the same way you can see them in the code

[background=rgb(250, 251, 252)]reading past the end--nop because the loop is around 2 million times and the data starts to get repeated at the 220 loop[/background]

the problem isn't in the soundfile, i had opened it(http://ie.microsoft....L5/TypedArrays/),i have played it too ,and i have opened with that code other soundfiles and at some point near the start the array starts to be filled with the same data until loop finishes.

This was wrong

cant find the problem

My first guess would be that the value of ivb is being read wrong?

Put a breakpoint on the for loop and make a note of the variables.

On other words, you need to make sure (ss/2) is the expected size for your data.
