actionscript 3 - AS3: setChildIndex of targetSection + "_mc" to FRONT / accessing buttons on alpha:0 MC -


i'm making customisation app in flash cs5 using as3 & greensock's timelinemax.

the navigation based on snorkl.tv bullet proof portfolio uses timelinemax jump labels in timeline, , alpha in appropraite mc. mcs [garment_mc,size_mc,design_mc,ink_mc,options_mc,checkout_mc] sit on same space on stage on separate layers, , tween x:-100 when button clicked.

this means when swf published top layer , it's mc cover other mcs, , when navigate lower mcs, displayed underneath alpha:0 mc, top-most mc's buttons/functions still clickable , affect previous choice (choose garment, next section, click on mc, registers on top-most mc).

i need navclick function include like... setchildindex(targetsection + "_mc", 0) have been getting 1067: implicit coercion errors.

can make suggestions why? or should here? im racing towards final hand-in date great, thank you!!

naigation code.

// section clips visible on stage //we don't want see them when swf starts //set array of section clips can start them alpha=0; var panel_clips = [garment_mc,size_mc,design_mc,ink_mc,options_mc,checkout_mc];  (var j:number = 0; j < panel_clips.length; j++) {     panel_clips[j].alpha = 0; }  ////  var tl:timelinemax = new timelinemax({}); tl.timescale = 1;   tl.addlabel("garment_in", tl.duration); tl.append(tweenmax.to(garment_mc, 0, {alpha:1, immediaterender:false})); tl.append(tweenmax.from(garment_mc, .5, {x:-100, y:0, ease:quart.easeout}));  tl.addlabel("garment_complete", tl.duration); tl.append(tweenmax.to(garment_mc, .5, {alpha:0}));    tl.addlabel("size_in", tl.duration); tl.append(tweenmax.to(size_mc, 0, {alpha:1, immediaterender:false})); tl.append(tweenmax.from(size_mc, .5, {x:-100, y:0, ease:quart.easeout}));  tl.addlabel("size_complete", tl.duration); tl.append(tweenmax.to(size_mc, .5, {alpha:0}));    tl.addlabel("design_in", tl.duration); tl.append(tweenmax.to(design_mc, 0, {alpha:1, immediaterender:false})); tl.append(tweenmax.from(design_mc, .5, {x:-100, y:0, ease:quart.easeout}));  tl.addlabel("design_complete", tl.duration); tl.append(tweenmax.to(design_mc, .5, {alpha:0}));    tl.addlabel("ink_in", tl.duration); tl.append(tweenmax.to(ink_mc, 0, {alpha:1, immediaterender:false})); tl.append(tweenmax.from(ink_mc, .5, {x:-100, y:0, ease:quart.easeout}));  tl.addlabel("ink_complete", tl.duration); tl.append(tweenmax.to(ink_mc, .5, {alpha:0}));   tl.addlabel("options_in", tl.duration); tl.append(tweenmax.to(options_mc, 0, {alpha:1, immediaterender:false})); tl.append(tweenmax.from(options_mc, .5, {x:-100, y:0, ease:quart.easeout}));  tl.addlabel("options_complete", tl.duration); tl.append(tweenmax.to(options_mc, .5, {alpha:0}));   tl.addlabel("checkout_in", tl.duration); tl.append(tweenmax.to(checkout_mc, 0, {alpha:1, immediaterender:false})); tl.append(tweenmax.from(checkout_mc, .5, {x:-100, y:0, ease:quart.easeout}));  tl.addlabel("checkout_complete", tl.duration); tl.append(tweenmax.to(checkout_mc, .5, {alpha:0}));   //set nav  navmc.addeventlistener(mouseevent.mouse_over, navover); navmc.addeventlistener(mouseevent.mouse_out, navout); navmc.addeventlistener(mouseevent.click, navclick); navmc.buttonmode = true;  navmc.garmentbtn.id = "garment"; navmc.sizebtn.id = "size"; navmc.designbtn.id = "design"; navmc.inkbtn.id = "ink"; navmc.optionbtn.id = "options"; navmc.checkbtn.id = "checkout";  function navover(e:mouseevent):void {     //tweenmax.to(e.target, .5, {tint:0x00ccff});     e.target.nextframe();     //e.target.gotoandstop(e.target.nextframe);     //trace("rolled"); }  function navout(e:mouseevent):void {     //tweenmax.to(e.target, .5, {tint:null});     //trace(e.target.id);     e.target.gotoandplay(1); }    function navclick(e:mouseevent):void {     trace(e.target.id);     targetsection = e.target.id;     if (targetsection != currentsection)     {         e.target.gotoandplay(2);         --> ?? //setchildindex(targetsection + "_mc", 0)    <--------??????         tl.tweenfromto(targetsection + "_in", targetsection + "_complete");         currentsection = targetsection;       }else{         trace("you @ " + currentsection);         }  }   //play through home1_complete automatically on first run tl.tweento("garment_complete");   //

in navclick function change line:

targetsection = e.target.id;

like this:

targetsection = e.target;

because setchildindex function first argument needs child movie , not name/id.

edited: in case may should try this:
setchildindex( getchildbyname(e.target.id + "_mc"),0);

php - Why I am getting the Error "Commands out of sync; you can't run this command now" -

the documentation of error mentioned in title says if commands out of sync; can't run command now in client code, calling client functions in wrong order. this can happen, example, if using mysql_use_result() , try execute new query before have called mysql_free_result(). can happen if try execute 2 queries return data without calling mysql_use_result() or mysql_store_result() in between. from here: http://dev.mysql.com/doc/refman/5.0/en/commands-out-of-sync.html but in first query not fetching data mysql database, inserting. , in second query getting data database. here code $connection = mysqli_connect("localhost","username","password","tbl_msgs"); if(mysqli_connect_errno($connection)) { die("failed connect mysql: " . mysqli_connect_error()); } $query = "insert users (total_comments, total_views) values ({$total_comments}, {$total_views});"; $query .= "insert msgs (no...

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
