2) how can unload class of child swf?(becoz there many ext. swf different class)

thx

main.fla

 function startload(){     var mloader:loader = new loader();     var mrequest:urlrequest = new urlrequest("game1.swf");     var mloadercontext:loadercontext = new loadercontext(false,applicationdomain.currentdomain);     mloader.contentloaderinfo.addeventlistener(event.complete, oncompletehandler);     mloader.contentloaderinfo.addeventlistener(progressevent.progress, onprogresshandler);     mloader.load(mrequest, mloadercontext); }  function oncompletehandler(loadevent:event){     var keymanager:class = applicationdomain.currentdomain.getdefinition("net.keithhair.keymanager") class;     addchild(loadevent.currenttarget.content); }

game1.fla

    import net.keithhair.keymanager;      keymanager=new keymanager(stage);     keymanager.addkey(["a"], dosomething);     function dosomething():void {     //do       }

result:

typeerror: error #1009: cannot access property or method of null object reference. @ net.keithhair::keymanager/removelisteners() @ net.keithhair::keymanager/addlisteners() @ net.keithhair::keymanager() @ game1_fla::maintimeline/frame1() 

function constructor(){    if (stage){       onaddedtostage();    } else {       addeventlistener(event.added_to_stage, onaddedtostage);    } }  function onaddedtostage(evt:event=null):void {     var keymanager:keymanager;     trace("here!")     keymanager=new keymanager(stage);     keymanager.addkey(["a"], dosomething } constructor();

the above code solve problem. thank destinier & senocular

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
