i'm trying have image inside div of same width draggable in limit of div. it's difficult explain 1 side of image (top or bottom) can leave div cannot have gap between edge of image , border of div. to resume image has same width of parent div height bigger part of image hidden. well here want do: http://jsfiddle.net/maxwell2022/derna/165/ it's working perfectly... because there nothing above div. if there gap between document , div, it's not working anymore. think draggable taking document reference top of image. start dragging image, image move , stuck top edge top of document: http://jsfiddle.net/maxwell2022/derna/164/ i don't know how can achieve containment option. cheers, maxime update another attempt relative positioning no luck: http://jsfiddle.net/maxwell2022/derna/166/ i found solution fix getting top position of parent div using offset() , add containment boundary. i'm not sure it's best solution looks it's work...

i helping out friend of mine bit stuck , own c++ skills rusty. interest , curiosity quite picked this. shall try , explain best can. note 32 bit check. uint32_t crc32::calculate_crc32(const uint32_t* pldata, uint32_t llength, uint32_t previouscrc32) { uint32_t lcount; const uint32_t lpolynomial = 0x04c11db7; uint32_t lcrc = previouscrc32; unsigned char* plcurrent = (unsigned char*) pldata; lcrc ^= *plcurrent++; while (llength-- != 0) { (lcount = 0 ; lcount < llength; lcount++) { if (lcrc & 1) lcrc = (lcrc >> 8) ^ lpolynomial; else lcrc = lcrc >> 8; } } return lcrc; } now ilength number of bytes packet contains. pldata packet data needs checked. is, function works. works bit bit. needs improved work byte byte. genius c++ developers out there far surpasses knowledge. ideas helpful. in advance guys. read ross williams excellent tutorial on crcs , s...
