C/C++ Coding Problems & Questions [EHM 2005]

[Midas]

As requested Archie, here's the code I'm using:

Code: Select all

#include <iostream>
#include <fstream>

#pragma pack(1)                                       // This is essential because the data in the .dat files are byte-swapped
#include "database_types.h"                              // The three EHM database format .h files must be called after #pragma pack(1)
#include "database_flags.h"
#include "language_types.h"

using namespace std;                                 // As we are just using the standard library, we'll use std namespace for ease of reference

int main() {

   fstream dat_infile ("index.dat", ios::in | ios::binary);   // Open index.dat for reading in binary mode. We'll call it dat_infile.
   fstream csv_outfile ("index.csv", ios::out);            // Create a blank index.csv file in text mode. We'll call it csv_outfile.

   struct INDEX dat;                                 // Within the database_types.h file the structure of index.dat INDEX
                                                // We'll assign "dat" as the identifier for use with this structure

   // Calculate the length of index.dat and call is dat_filesize:
   dat_infile.seekg (0, ios::end);
   auto dat_filesize = dat_infile.tellg();
   dat_infile.seekg (0, ios::beg);

   if (dat_infile.is_open())                           // If index.dat has been successfully opened then perform the following code within the {} braces
   {
      dat_infile.seekg(INDEX_IGNORE_DATA,ios::beg);         // DELETE THIS LINE IF YOU ARE OPENING ANY FILE OTHER THAN INDEX.DAT
                                                // The first 8 bytes of index.dat are blank and therefore we must skip over these. Hence the reason of the line above.

      // A loop to read the data stream into the buffer one record at a time and save it as a csv file
      while( dat_infile.tellg() < dat_filesize )
      {
         dat_infile.read ((char*)&dat, sizeof(INDEX));
         csv_outfile << dat.filename << "," << dat.file_id << "," << dat.table_sz << "," << dat.version << endl;      // Commas are added between each field as per csv file format. The final field of each record is terminated by a new line - i.e. 'endl'.
      }

      // Close the index.dat and index.csv files
      dat_infile.close();
      csv_outfile.close();
   }

   else                                          // If index.dat cannot be opened then do the following
   {
      cout << "Unable to open index.dat" << endl;
   }

   cout << "Press ENTER to close this window.";
   cin.get();                                       // Wait until the user has pressed ENTER before closing the window

   return(0);                                       // Exit the script / close the window.
}

It's Visual C++ 2010 Express and pulled it straight out of your tutorial. I downloaded the EHM 2005 database and just plugged it in. I'm terrible atm. with C++ but playing around with this should get me to improve.

This is the error message list.

If you need more information, I'd be happy to post. Thanks!

I had some spare time this evening so I took a look for you. The problem is because of some mistakes in the database_types.h file. There were similar mistakes with the EHM 07 .h file too, but I corrected these a while back when I first started coding. I'd never touched the EHM 05 .h files before.

Anyway, I've uploaded a corrected copy of the .h files here: http://www.ehmtheblueline.com/forums/vi ... 85#p127185

Replace your original database_types.h file with the updated one from the link above. This will fix all of the syntax errors.

It does look, however, that you're using a Win32 project. When you created the project in MSVC++ 2010 Express, you should select the 'Empty Project'' option.

One final note: When I wrote those guides, I was still very new to C++. With the benefit of (some) experience I'd do things a little differently now (and I'd use classes/OOP too). If you run into a brick wall or struggle with anything then just post your code here and I'll be happy to help.

Thanks for the help Archie, I did indeed get it to work. Glad you could show me the light!

Alright so I know I have this all mucked up, but I wanted clarification on what specifically

I'm trying to export the staff.dat to .csv but debugger can't process the SI_DATE. I know you posted some stuff on it, I tried my hand and it and no doubt butchered it. When you have time, can you have a look at what's going wrong here?
