iphone - Do tagged images occupy memory/locations? -

-

i wondering if tagged images can occupy memory/locations (i'm not sure call them call them memory/locations)...

the code below used find matches , removes them view when 3 or more in row/column. thing though seems if statements works once. once have been used stop finding matches.

is there way of "releasing" occupied if statements or there way of doing this?

for( int y=0; y<height-2; y++ ){ for( int x=0; x<width-2; x++ ){      //don't match empty squares     if(grid[x][y] == nil){         continue;         nslog(@"continue");     }      if(x >= 2 && x <= width -2  && y >= 2 && y <= height - 2) {          //check right         if(grid[x+1][y].tag == grid[x][y].tag && grid[x+2][y].tag == grid[x][y].tag) {              nslog(@"to right");              grid[x][y].alpha = 0;             grid[x+1][y].alpha = 0;             grid[x+2][y].alpha = 0;               nslog(@"match right grid[x][y].tag %d",grid[x][y].tag);             nslog(@"match right grid[x+1][y].tag %d",grid[x+1][y].tag);             nslog(@"match right grid[x+2][y].tag %d",grid[x+2][y].tag);          }          //check left         else if (grid[x-1][y].tag == grid[x][y].tag && grid[x-2][y].tag == grid[x][y].tag){              nslog(@" left");              grid[x][y].alpha = 0;             grid[x+1][y].alpha = 0;             grid[x+2][y].alpha = 0;              nslog(@"match left grid[x][y].tag %d",grid[x][y].tag);             nslog(@"match left grid[x-1][y].tag %d",grid[x-1][y].tag);             nslog(@"match left grid[x-2][y].tag %d",grid[x-2][y].tag);          }          //check         else if(grid[x][y-1].tag == grid[x][y].tag && grid[x][y-2].tag == grid[x][y].tag){              nslog(@"up");                 grid[x][y].alpha = 0;             grid[x][y-1].alpha = 0;             grid[x][y-2].alpha = 0;                       nslog(@"match grid[x][y].tag %d",grid[x][y].tag);             nslog(@"match grid[x][y-1].tag %d",grid[x][y-1].tag);             nslog(@"match grid[x][y-2].tag %d",grid[x][y-2].tag);          }          //check down         else if(grid[x][y+1].tag == grid[x][y].tag && grid[x][y+2].tag == grid[x][y].tag){              nslog(@"down");              grid[x][y].alpha = 0;             grid[x][y+1].alpha = 0;             grid[x][y+2].alpha = 0;              nslog(@"match down grid[x][y].tag %d",grid[x][y].tag);             nslog(@"match down grid[x][y+1].tag %d",grid[x][y+1].tag);             nslog(@"match down grid[x][y+2].tag %d",grid[x][y+2].tag);          }      else{         gamepaused = no;     } }

}

no, don't take memory. assigned identified uniquely in parent.

hey, struggling bit determine exact cause of error has been popping in our release environment. there not seem dealing particular error on google. this error message getting: sqlstate[34000]: invalid cursor name: 7 error: portal "" not exist the error pops when using pdo prepared statements. this setup our release environment: pgpool 3.0.1 (the postgresql backend in streaming replication mode!) php 5.3.5 postgresql 9.0 edit: architecture 64bit. the same error not manifest in our test environment (edit: forgot mention, standard test environment uses postgresql 9.0 without pgpool). thus, led suspect pgpool @ least partly suspect. does know probable causes error are? edit: ok, here example of kind of code causes error. $sql = 'select * '; $sql .= 'from "mytable" "mystuff" '; $sql .= 'where "mytable"."status" = 1 '; $sql .= 'and "mytable"."mytableid" = :table...

why need use because printers using tprinter prints weird hieroglyph @ beginning of printable area. my problem if send commands, nothing happens. esc e (#27 #69) - sending escape sequence didn't work expected. removed first letter , rest of string made bold. eg. hello -> ello . after changed esc e esc (#27 #69 #27), worked fine. example managed figure out, but... trying select character table "esc t n" (#27 #116 n), make "õäöü" work. command doesn't work. nothing happens! , command supported esc/p, esc/p 2 , 9-pin esc/p, should work fine. manual can found here . if has ever needed use esc/p commands maybe 1 can shed light how work them! thanks in advance! edit: in previous post asked more or less same question though answers how did send commands printer. (i'll change question there according answers!) i accepted ken's answer, because claimed way transferred commands wasn't best , got work escape command. problem after t...
