Randomly line reads

[MrAlicard]

Hello
I want to solve it randomly reads the lines.
I found a source code, but it will crash the program.

This is source code:

DWORD cFindEvent::GetRandomPosition()
{
   //---------------------------------------------------------------------------------------
   FILE * garew = fopen (MobCoords,"r");
   //---------------------------------------------------------------------------------------
   char temp[1024];
   int i = 0;
   int j = 0;
   int licz = rand() % 100;
   //---------------------------------------------------------------------------------------
   while ( !feof(garew) && i <= licz)
   {
      //-----------------------------------------------------------------------------------
      fgets(temp , 1024 , garew );
      //-----------------------------------------------------------------------------------
      if(temp[0] != '/' && temp[1] != '/')
      {
         //-------------------------------------------------------------------------------
         sscanf(temp,"%d %d %d", &DayMap, &DayX, &DayY);
            if(DayMap >= 0)
         {
            //---------------------------------------------------------------------------
            i++;
            //---------------------------------------------------------------------------
         }
         //-------------------------------------------------------------------------------
      }
      //-----------------------------------------------------------------------------------
   }
   //---------------------------------------------------------------------------------------
   fclose(garew);
   //---------------------------------------------------------------------------------------
   FILE * garew2 = fopen (MobCoords,"r");
   //---------------------------------------------------------------------------------------
   if(licz > i)
   {
      //-----------------------------------------------------------------------------------
      int licz2 = rand() % i;
      //-----------------------------------------------------------------------------------
      while ( j <= licz2 )
      {
         //-------------------------------------------------------------------------------
         fgets(temp , 1024 , garew2 );
         //-------------------------------------------------------------------------------
         if(temp[0] != '/' && temp[1] != '/')
         {
            //---------------------------------------------------------------------------
            sscanf(temp,"%d %d %d", &DayMap, &DayX, &DayY);
            if(DayMap >= 0)
            {
               //-----------------------------------------------------------------------
               j++;
               //-----------------------------------------------------------------------
            }
            //---------------------------------------------------------------------------
         }
         //-------------------------------------------------------------------------------
      }
      //-----------------------------------------------------------------------------------
   }
   //---------------------------------------------------------------------------------------
   fclose(garew2);
   //---------------------------------------------------------------------------------------
    DWORD Reward = DNState.DayBossIndex=CreateMobInXY(21,DayMap,DayX,DayY);
   Chat.MessageAll(0,0,NULL,"The monster entered the coordinates: %d x %d", DayX, DayY);;
   //---------------------------------------------------------------------------------------
   return Reward;
   //---------------------------------------------------------------------------------------
}

What's wrong with this?

[richieking]

so what have you done personally here. Do something, show your errors and we might/may help you. Thats how we do it over here.

This has included:

#define MobCoords             "..\\Config\DayCoords.txt"

int DayMap;
int DayX;
int DayY;
int DayBossIndex;

When it starts the event the server program will crash.
