FileName

Using MS Visual Studio C++

I am using a function that I wrote which will create a string. The string will have the date & time which is preceeded by a letter that is a function arg to identify the output file type. This string is used to make the output file for the program. However, when I use this function to output two different files, the underscore is used in the first file, but on the second use, the underscore turns into a 0 (zero). This happens when I change the underscore to a random ascii character. Please view the code. I'd like to know how I can use the underscore in both filenames that are created consecutively.

Your attached files are missing information and are generally illegible.

I'm guessing that he is having some trouble with this function. ;)

Code:

---

char *OutNameTime(char *cLetter)       
{
        char *cTimeFile;

        struct tm *newtime;
    time_t long_time;
    time(&long_time);                                                // Get time as long integer.
    newtime = localtime(&long_time);                // Convert to local time.
        char *chTime = asctime(newtime);
        char cFileStr[17];
       
        //        This is for the year
        cFileStr[0] = chTime[20];
        cFileStr[1] = chTime[21];
        cFileStr[2] = chTime[22];
        cFileStr[3] = chTime[23];
       
        //        This is for the month
        cFileStr[4] = chTime[4];
        cFileStr[5] = chTime[5];
        cFileStr[6] = chTime[6];
       
        //        This is for the day
        cFileStr[7] = chTime[8];
        cFileStr[8] = chTime[9];

        char *cUnderScore = "_";
        cFileStr[9] = *cUnderScore;
       
        //        This is for the time
        cFileStr[10] = chTime[11];
        cFileStr[11] = chTime[12];
        cFileStr[12] = chTime[14];
        cFileStr[13] = chTime[15];
        cFileStr[14] = chTime[17];
        cFileStr[15] = chTime[18];

        char *cPath = "C:\\TrackerFiles/Tracker2File/";
        cTimeFile = cPath;
        cTimeFile[29] = *cLetter;
        cTimeFile[30] = cFileStr[0];
        cTimeFile[31] = cFileStr[1];
        cTimeFile[32] = cFileStr[2];
        cTimeFile[33] = cFileStr[3];
        cTimeFile[34] = cFileStr[4];
        cTimeFile[35] = cFileStr[5];
        cTimeFile[36] = cFileStr[6];
        cTimeFile[37] = cFileStr[7];
        cTimeFile[38] = cFileStr[8];
        cTimeFile[39] =        cFileStr[9];
        cTimeFile[40] = cFileStr[10];
        cTimeFile[41] = cFileStr[11];
        cTimeFile[42] = cFileStr[12];
        cTimeFile[43] = cFileStr[13];
        cTimeFile[44] = cFileStr[14];
        cTimeFile[45] = cFileStr[15];
        cTimeFile[46] = NULL;

        return(cTimeFile);
}

I can't read those files, not all of them at least, and they are not wrapped/formatted. Anyway, what happens if you...

cFileStr[9] = '_';

... instead?

Wouldn't strftime make this much simpler?

Code:

---

char *OutNameTime(char *cLetter)
{
  static char cTimeFile [ 47 ];
  time_t now = time(0);
  struct tm *local = localtime(&now);
  if ( local )
  {
      strftime(cTimeFile, sizeof cTimeFile,
              "C:\\TrackerFiles/Tracker2File/?%Y%b%d_%H%M%S", local);
      cTimeFile[29] = *cLetter;
  }
  return cTimeFile;
}
