[HELP] Saving data into a file - Pooh7 - 09.12.2010

Hi

File functions, savings, readings, etc are my nightmear

I'm total noob for file functions

Ok, I have this func for saving vehicles (ownership):

pawn Code:

public SacuvajVozila()
{
    new idx;
    new File: file2;
    while (idx < sizeof(Vozilo))
    {
        new coordsstring[256];
        format(coordsstring, sizeof(coordsstring), "%d,%f,%f,%f,%f,%d,%d,%s,%s,%d,%d\n",
        Vozilo[idx][hModel],
        Vozilo[idx][hPozX],
        Vozilo[idx][hPozY],
        Vozilo[idx][hPozZ],
        Vozilo[idx][hPozA],
        Vozilo[idx][hBoja1],
        Vozilo[idx][hBoja2],
        Vozilo[idx][hVlasnik],
        Vozilo[idx][hOpis],
        Vozilo[idx][hCena],
        Vozilo[idx][hImaVlasnika]);
        /*if(idx == 0)
        {
            file2 = fopen("VozilaOwnership.cfg", io_write);
        }
        else
        {
            file2 = fopen("VozilaOwnership.cfg", io_append);
        }*/
        file2 = fopen("VozilaOwnership.cfg", io_write);
        fwrite(file2, coordsstring);
        idx++;
        fclose(file2);
    }
    return 1;
}

This function is called in GameModeExitFunc (godfather mode)
My problem is that when i restart my server (gmx), new vehicles data is just add into a file.
For example, this is one line from VozilaOwnership.cfg:

Code:

411,551.633239,-1263.060302,17.042186,215.000000,20,1,Autosalon,Infernus,1000000,0

When someone buy this car, script will create new line:

Code:

411,551.633239,-1263.060302,17.042186,215.000000,20,1,Firstname_Lastname,Infernus,1000000,1

The problem is that what new line just add on end of file.
I want to replace the existing line with that new line.

How to do that?

Sorry for my bad English.

WTF is this?
Explane please

Re: [HELP] Saving data into a file - Pooh7 - 10.12.2010

It's a vehicle ownership.
And update for some car is just add on end of file.
I want to replace existing line with new vehicle data.
This updates on end of file are not loading, because in it's over a limit. Limit is 64 vehicles, and I have 64 lines in my cfg file. So, updates can't be load.
If i increase a limit, vehicles will be double (only updated vehicles).

How to set replacing, not adding?

He means that instead of creating any new line, just want it replaced with the new information of the new car the player bought.

Try.:

pawn Code:

public 
    SacuvajVozila()
{
    new 
        idx = 0,
        File:file2 = fopen("VozilaOwnership.cfg", io_write);  // io_write
    if(file2)
    {
        new 
            coordsstring[256];
        while(idx < sizeof(Vozilo)) // Loop 64   0. - 63.  
        {
            format(coordsstring, sizeof(coordsstring), "%d,%f,%f,%f,%f,%d,%d,%s,%s,%d,%d\r\n", // \r\n new line
                Vozilo[idx][hModel],
                Vozilo[idx][hPozX],
                Vozilo[idx][hPozY],
                Vozilo[idx][hPozZ],
                Vozilo[idx][hPozA],
                Vozilo[idx][hBoja1],
                Vozilo[idx][hBoja2],
                Vozilo[idx][hVlasnik],
                Vozilo[idx][hOpis],
                Vozilo[idx][hCena],
                Vozilo[idx][hImaVlasnika]);
            fwrite(file2, coordsstring);
            idx++;
        }
        fclose(file2); // Close the opened file 
    }
    return 1;
}
