Retrieving one line from a player file. - Binx - 18.08.2013

Hello,

I have a player file created with Y_INI, however I only want to load one line from this file. The way I want to do this is with native SAMP File Functions (Found here: https://sampwiki.blast.hk/wiki/File_Functions), however I cannot make head or tail of it.

The line I want to retrieve is: "IP = ***.***.***.***"

I do not want to parse the whole file as the player isn't going to be actively online for this function, however I also don't want to use Y_INI to parse one line of information.

I have tried attempting this myself:

pawn Код:

new File:PlayerIP = fopen(LuckyGuy, io_read);
    new string[15 + 5];
    while(fread(PlayerIP, string))
    {
        if(strcmp(string, "IP = ", true)==0)
        {
            strmid(string, string, 5, 20, 15);
        }
    }

    format(LuckyGuy, sizeof(LuckyGuy), Ban_Path, string);
    if(fremove(LuckyGuy)) return SendClientMessage(playerid, COLOR_RED, "|-- Error: Account Deletion Failed!");

As you can see here I am trying to delete a ban file using the IP from within "LuckyGuys" file, which I have set this to the correct path.

pawn Код:

format(LuckyGuy, sizeof(LuckyGuy), PATH, LuckyGuy);

This is shown here by the inital LuckyGuy result back from sccanf is being formatted into string.

        string[len-2] = 0;
        strdel(string,0,5);

fclose(PlayerIP);

if(!fremove(LuckyGuy)) return SendClientMessage(playerid, COLOR_RED, "|-- Error: Account Deletion Failed!");

when I type their correct name, it says it's an unknown command, with the "break".

You need type some IP and use print under every line then you will see where code stops

pawn Код:

CMD:unban(playerid, params[])
{
    new LuckyGuy[MAX_PLAYER_NAME + 6 + 4];
    if(PlayerInfo[playerid][pAdmin] <= 4) return SendClientMessage(playerid, COLOR_RED, "Error: "COL_WHITE" You're not a high enough Administrator.");
    if(sscanf(params, "s[24]", LuckyGuy)) return SendClientMessage(playerid, COLOR_RED, "Error: "COL_WHITE"/unban [Name] (Example: Jammie Dodger)");

    format(LuckyGuy, sizeof(LuckyGuy), PATH, LuckyGuy);

    if(!fexist(LuckyGuy)) return SendClientMessage(playerid, COLOR_RED, "Error: Player doesn't exist! (Tips: Don't use _ | Example Jammie Dodger)");

    new INI:File = INI_Open(LuckyGuy);
    print("File opened");
    INI_SetTag(File, "Statistics");
    print("SetTag");
    INI_WriteInt(File, "Banned", 0);
    print("Set banned");
    INI_Close(File);
    print("Closed File.");
    
    new File:PlayerIP = fopen(LuckyGuy, io_read);
    new string[16 + 7],len;
    while((len = fread(PlayerIP, string)))
    if(strcmp(string, "IP = ", true)==0)
    {
        string[len-2] = 0;
        strdel(string,0,5);
        break; // stop searching
    }

    format(LuckyGuy, sizeof(LuckyGuy), Ban_Path, string);
    if(!fremove(LuckyGuy)) return SendClientMessage(playerid, COLOR_RED, "|-- Error: Account Deletion Failed!");
    SendClientMessage(playerid, COLOR_GREEN, "Account Unbanned!");
    return 1;
}

This says Unknown command..
"/ban player name" 2 parameters? It says it's an unknown command.

E: This is the debug although it said it's an unknown command:

Код:

[19:53:48] File opened
[19:53:48] SetTag
[19:53:48] Set banned

new File:PlayerIP = fopen(LuckyGuy, io_read);
new string[50], Ip[20];
while (fread(PlayerIP, string))
{
     if(!strcmp(string, "IP = ",true, strlen("IP = ")))
     {
            strmid(Ip, string, strlen("IP = "), strlen(string) - 2);
     }
}
