javascript - Write to file in JS using XMLHttpRequest? -


i figured out how read local .txt file on server js using xmlhttprequest api life of me cant write file. possible or reading files in?

my code read in works fine:

var freader = new xmlhttprequest();  freader.onreadystatechange=function() {   if(freader.readystate==4 && freader.status==200) {     parsetext(freader.responsetext);//processes file. }} freader.open("get",ffileloc,true); freader.send();

i'm using php write file, it's far ideal. i'd js it. thoughts? there approach doing this? php way?

thanks in advance,

-dave

edit: @rjmunro +others: found using php better way go this... revised code follows. (c&c welcome).

js:

var freader = xmlhttprequest(); //var params = "mode=get&file=data.txt";//to read //var params = "mode=post&file=data.txt&message=" + mymessage;//to write      freader.onreadystatechange=function() {         if(freader.readystate==4 && freader.status==200) {             //not response text if writing...             parsetext(json.parse(freader.responsetext).get);         }     }      freader.setrequestheader("content-type", "application/x-www-form-urlencoded");     freader.setrequestheader("content-length", params.length);     freader.setrequestheader("connection", "close");      freader.send(params);

php

$mode = $_post['mode']; switch($mode) {     case('get'):       #read in file , process, return output.       $return['get'] = file($_post['file']);     break;      case('post'):         if(file_exists($_post['file'])){             $file = fopen($_post['file'],"a");              $data = $_post["message"];              fwrite($file,$data);             fclose($file);         }     #$return['post'] = "some message?";     break; } echo json_encode($return);

the thing i'm not 100% on solution why have setrequestheader? chrome doesnt seem this... pulled code post.

you can configure apache accept put requests, send 1 using xmlhttprequest (i'd use jquery.ajax() abstract this).

it's better have php (or server side language) handle you, though, difficult control authentication using apache.

c++ - Correct method for redrawing a layered window -

i have window created ws_ex_layered window style. drawing onto memory bitmap using gdi+, , using updatelayeredwindow update graphical content of layered window. intend use window main window of application, require redraw frequently. seeing layered windows not receive wm_paint windows message [?] , need come appropriate method re-drawing window. optimisation not essential , it's nice have cake , eat too. therefore, in search of "correct" method use. here thoughts far: i guess it's idea render onto off-screen bitmap before bitblt ing or similar. 60 frames rendered per second should (more than?) enough (but how compare other applications' frame rates?). possible solutions: use settimer send wm_timer message on regular basis. useful because through specifying time-out value, can achieve desired frames per second, without requirement measure duration "frame" takes rendered. would cause input or other lags due frequency , speed of m...
