file. sorry, carlos is right, you need a char*

  You say char buffer, it shall be char *buffer, the function expects a
pointer.

    Hi List,

    i have a problem readding a binary file.

    I have a 1.3 MB File, and i hav to read 2048 bytes (if != eof),

    if have tryed it with ReadFile() but i every time get an acces violation
...

    My last try was ifstream:


    #include "stdio.h"
    #include "fstream.h"
    #include "windows.h"


    int main(int argc, char* argv[])
    {
     char buffer;
     int nRead = 0;

     ifstream *fb = new ifstream;
     fb->open("c:\\out.cal");

     if(fb->fail() != 0)printf("Cant opne\n");

     fb->seekg(0);

     while (!fb->eof())
     {
      fb->read(buffer, 2048);
      nRead = nRead + 2048;
      printf("%i\n", nRead);
     };

     getchar();
     return 0;
    }


    If I execute this I get an acces voilation after the read function ...


    Does any one have an idea ?


    Kind r
