for information on how your program can cause an assertion failure,see
the visual c++ doucmention on asserts.
(please retry to debug the application)
abort(A) retry(R) ignore(I)

can someone give me a suggestion ,where's the fopen.c what dose
*file !=_T('\0') mean,and where can
i get documentation on asserts?
ps. befor it occures,my program run at :
        if (!fout.is_open ())
        {
                cerr << "Can't open file: " << fileName;
                exit(EXIT_FAILURE);
        }
and if i select ignore
the cmd windows display Can't open filepress any key
to continue.
thanks a lot!

It tells you that you have passed a string of length 0 (the first
character is \0) as the filename to fopen.
assert should be described in your favourite C/C++ book - if it is
not, use google.
