    Problem in Reading File.

    Hi all,

    i am reading a file with help of CStdioFile using while loop and read the file till file reached end of file,in the file somewhere  symbol exist,when reading this line with ReadString ,while loop becomes infinite loop and not return and application goes in notresponding state.

    please tell me how can i read the full file with this symbol or how can i remove this symbol from file before reading the file.

    thanks in advance.

    you can judge the return of ReadString,

    from MSDN:
    Return Value

    A pointer to the buffer containing the text data. NULL if end-of-file was reached without reading any data; or if boolean, FALSE if end-of-file was reached without reading any data.

    if i do this ,function not read the full file and return when this symbol occur becoz here ReadFile return 0,but i want to read full file data.

    Did you open the file in binary mode?

    CStdioFile in combination with ReadString, doesn't really like for the file to contain binary zeroes.
    If you can't assure that the file will not contain binary zero's, Go with using the plain Read(), and do the line processing yourself.
