now are you sure fscanf reads until '\n' as in new line, or '\0' as in the NULL character. plus do i have to put terminating character in the search item like "%s\n"?
here is why i am asking is the following line:

//FILE *infile = fopen(filename);//string stream;fscanf(infile, "%s", stream.c_str());  

i have tried with both stream normally and stream.c_str() (as above). both ways crash on me and get the wonderful error "Access Violation."

the third parameter MUST be a char* if you read a string(or an array of char)

and it reads what you tell him to read.
if you tell him %d it will read only sizeof int, no matter what''s after that,
if you tell him "%d\n" it will suppose that after the int there is a newline
so to read a line you must tell him %s\n

the access violation you are getting it''s because c_str() if i don''t remember badly return the pointer to the string, but that string is empty now, so it''s not allocated anything so c_str() returns null i think, and it cannot save the string in "null"

to resolve this make a char buffer[32523634] save the string there and then copy it in the stream
in C there are not streams ( i think)

omg omg omg omg omg!!! i finally have this thing working after SO MANY WEEKS of struggling! thank you guys SO MUCH!!! especially you Thor82 for helping me in the last few posts. i have one more problem, which is something i can fix. my program is just rendering one box instead of the 2 boxes it needs to. o well. thank you guys once again!!

grrrr. i knew i would be back with more troubles. does anyone have any idea why fscanf could be converting values from strings to float or integer values wrong? i keep getting some integers in scientific notation.
plus another problem i have been having is getting the program to run twice in a row without giving some strange errors and range checking errors. just need some tips for stability.

can you paste some code please or send me in email:thor82 at libero.it

try using the stl "vector"...it''s easier and it handles everything

or try using old c calloc ( array= (int*) calloc(n,sizeof(int)))

in this way it stores n*sizeof(int) bytes...
it''s not the best way though....

This if statement is absolutley uneccessary, as the new operator will throw an exception on failure. The code should look something like this: ...

MSDN
If there is insufficient memory for the allocation request, by default operator new returns NULL. You can change this default behavior by writing a custom exception-handling routine and calling the _set_new_handler run-time library function with your function name as its argument. For more details on this recovery scheme, see The operator new Function.
