"SERVER: Unknown Command" problem.. - Kyance - 05.06.2014

Whenever i try using the command, i get "SERVER: Unknown Command".
It's in a filterscript, but everything else in the filterscript works just fine.

Load crashdetect plugin for that. Until then, I found 2 things.

pawn Код:

printf("* zBlock: LOGIN! %s has logged in the zBlock 'CP'!", GetName(playerid), SecondParam);

1 placeholder and 2 arguments.

The last one and most important, you should check if the file handle is valid before using any file function because it can crash the server. For example, this (from your code) is incorrect:

pawn Код:

new
    File: zBlockstuff = fopen("/zblock/password.txt", io_read)
;
fread(zBlockstuff, string);
fclose(zBlockstuff);

It should be:

pawn Код:

new
    File: zBlockstuff = fopen("/zblock/password.txt", io_read)
;
if (zBlockstuff)
{
    fread(zBlockstuff, string);
    fclose(zBlockstuff);
}

Then in changepassword, you have:

pawn Код:

if(zBlockstuff)
{
    fopen("/zblock/password.txt", io_write);
    fwrite(zBlockstuff, SecondParam);
    fclose(zBlockstuff);
    
    format(messagestring, sizeof(messagestring), "zBlock: %s(%d) has changed the password to %s", GetName(playerid), playerid, SecondParam);
    SendMessageToAdmins(COLOR_NOTES2, messagestring);
    
    printf("* zBlock: PASS CHANGE! %s has changed the password to %s!", GetName(playerid), SecondParam);
}

opening a file without storing the file handle to a variable and closing another file handle.

If it doesn't exist, it creates the file and it's empty inside. Compare with strcmp, it could return 0 (that they're equal) though you've done a mistake:

pawn Код:

if(strcmp(string, "defaultpassword5791", true))

that checks if the text "string" holds is not "defaultpassword5791". It should be:

pawn Код:

if(!strcmp(string, "defaultpassword5791", true))

About the empty line in the file, you can do something like this:

pawn Код:

if (!fread(zBlockstuff, string))
{
    // it's empty, do whatever you want..
}
else
{
    if(!strcmp(string, "defaultpassword5791", true))
    {
        DefaultPass = 1;
        print("** zBlock: Server is using the default password\n** zBlock: Please change it for your own safety.");
    }
    else
    {
        DefaultPass = 0;
        print("** zBlock: Server is NOT using the default password\n** zBlock: The 'CP' is ready for use.");
    }
}

Haha, thank you!
So.. em, about that command.
Should i change the "if(strcmp(SecondParam, string, true) == 0)" to "if(!strcmp(SecondParam, string, true) == 0)"? ( Password checking )

No, you don't! It checks already if what strcmp returns is equal to 0.

pawn Код:

// an example:
if (a == 0)
// is same as:
if (!a)

both statements check if a is equal 0.
