I have a simple problem (I guess) with my code snippet... it does compile
without warnings and errors, it simply hangs my comp (it only accepts the
RESET button anymore). I'm almost sure it locks up in the do-while loop and
never comes back out (first time I use _dos_findfirst() & _dos_findnext()).
Please take a look.

void create_new_palette(void)
     {
     int z;
     char fullpath[22]="tiles.bmp\\";
     char filename[6];
     struct find_t chkfile;
     FILE *liste, *graphic;
     set_standard_colors();                                          <-does
nothing right now
     liste=fopen("tiles.bmp\\chktiles.lst","wb");
     if(_dos_findfirst("tiles.bmp\\*dt.bmp", 0, &chkfile))  <- seems to be
wrong
       do
         {
         fputc(chkfile.name[0], liste);
         fputc(chkfile.name[1], liste);
         fputc(chkfile.name[2], liste);
         fputc(chkfile.name[3], liste);
         fputc(chkfile.name[4], liste);
         fputc(chkfile.name[5], liste);
         graphic=fopen(chkfile.name, "rb");
         fseek(graphic, 54, SEEK_SET);
         for (z=0; z<255; z++)
             {
             Day_Color_Palette[z*3]=fgetc(graphic);
             Day_Color_Palette[z*3+1]=fgetc(graphic);
             Day_Color_Palette[z*3+2]=fgetc(graphic);
             fgetc(graphic);
             }
         fclose(graphic);
         strncpy(filename, chkfile.name, 6);
         strcat(fullpath, filename);
         strcat(fullpath, Night_Ending);
         graphic=fopen(filename, "rb");
         fseek(graphic, 54, SEEK_SET);
         for (z=0; z<255; z++)
             {
             Night_Color_Palette[z*3]=fgetc(graphic);
             Night_Color_Palette[z*3+1]=fgetc(graphic);
             Night_Color_Palette[z*3+2]=fgetc(graphic);
             fgetc(graphic);
             }
         fclose(graphic);
         check_palette_entries();        <- Only gives out a text at the
moment
         }
       while (!_dos_findnext(&chkfile));   <- I guess that's my big error
 --------- Code below isn't reached and I don't know why -------------------
     printf("\n\n  %i Colors added to Fake_Palette.", Colors_added);
     fclose(liste);
     getch();
     }

Can anyone tell me what I am doing wrong?
Thx, Maverick

P.S. : If there's another place for that type of questions please tell me.
