i have function contains delete in it: void vector::reserve(int n){ //if there need increase size of vector if (n > _size){ int* tamparr; //check new size of array should _capacity = n + (n - _capacity) % _resizefactor; tamparr = new int[_capacity]; //put in new array element have in curr array (int = 0; < _size; i++){ tamparr[i] = _elements[i]; } delete[] _elements; _elements = null;//this //put new array in _element _elements = new int[n]; (int = 0; < _size; i++){ _elements[i] = tamparr[i]; } delete[] tamparr; } } the class field is: private: //fields int* _elements; int _capacity; //total memory allocated int _size; //size of vector access int _resizefactor; // how many cells add when need reallocate for reason first time use function doesn't show errors , work perfect in second time stops in

so i'm wondering if can give me idea how something. have tabcontrol in application - load page - tabpage1 - 25-30 fields. on loading data - run loop save each control value .tag. have function called isdirty() checks each control's ctr.tag.tostring <> ctr.text. i'm having hard time figuring out how build quick handler check controls on form. tried using tagpage1.validating, doesn't anything. my isdirty() function looks this... private function isdirty() boolean isdirty = false each ctr control in tabpage1.controls if typeof ctr textbox , ctr.enabled = true if ctr.tag.tostring <> ctr.text isdirty = true end if end if 'more if statements comboboxes , such next end function i'm hoping able plug function in somewhere , call on if isdirty() msgbox "you have made change form" end if do have call on each control's selection changed?

i've installed plugin: https://tah.wordpress.org/plugins/geoip-detect/ the plugin seems work fine when test "lookup" within plugin, returns geo-information. when try implement code within 1 of wordpress pages doesn't work. $ip = $_server['remote_addr']; $userinfo = geoip_detect2_get_info_from_current_ip($ip); echo $userinfo->country->name; i'm calling function native woocommerce page single-products shown. fucntion returns nothing. have include more call function geoip_detect2_get_info_from_current_ip() ? i tried: <?php echo do_shortcode("[geoip_detect2 property='country']"); ?> it doesn't return either. i'm doing editing within godaddy's code editing tool, might missing errors. i have try implement geo ip in wordpress site http://iradiofind.com/stations/ . using http://www.geoplugin.net country info. got ip address using function function get_client_ip() { $ipaddress = '';
