i not have experience regarding #d animation. 1 better java open gl or c++? diffrence between java 3d , opengl? "which 1 better" needs metric possible answer. if performance metric, answer c++ , opengl. (among other things) because calls between java , native can little bit more time-consuming, , c++ has arrays more in line opengl expects. but if metric how java developer able make reasonable performance, answer java + opengl. java3d higher level api opengl.

i trying consume .net webservice cold fusion. methods having simple types working fine. having problems 1 particular method accepts byte[] array input. below sample webmethod declaration [webmethod] public avstatus scanstream(byte[] fileobject) { // code } and cold fusion code consuming service is <cffile action="readbinary" file="#filename#" variable="filedata"> <cfset b64file = #tobase64(filedata)#> <cfinvoke webservice = "http://xxx/scanservice.asmx?wsdl" method = "scanstream" returnvariable = "result"> <cfinvokeargument name="fileobject" value="#b64file#" /> </cfinvoke> this leads error web service operation scanstream parameters cannot found . can me out this? it seems binary data has been exposed bas64 string in coldfusion while byte[] exposed service xml array (of bytes

i saw method telephonymanager.getvoicemailalphatag() have no idea it's for. javadocs useless. in situations helps use source® - imho huge advantage of android on other platforms. on gsm phones gets down simrecords . apparently (after googling) alpha tag voicemail name mobile operator uses voicemail. if not set defaults "voicemail" in english this data (voicemail alpha tag & voicemail number) stored inside sim , set operator.

i need track visitors websites own using same script. i own both example.com , site.com i want insert site.com/track.aspx in example.com using iframe. track.aspx insert flash-cookie visitor machine , save data db. how it? can achieve same result without using iframes? this re-redirect mechanism. track.aspx write cookie site.com domain, want cookie can read in example.com domain (i assume) create page in example.com writes cookies , redirects site.com create page in site.com redirects example.com have site.com/firstpage.aspx redirect example.com/writecookie.aspx?val=abc have example.com/writecookie.aspx write cookie , redirect site.com/track.aspx stick site.com/firstpage.aspx iframe, , let it's re-redirecting.

i retrieving size of files in document directory. using method attributesofitematpath so. successful. getting output in form of bytes , of class nsnumber . does'nt good. so, need output in kbs or mbs , have convert them nsstring in order store in nsdictionary have display in tableview. please me so. thank you. here code.. directorycontent = [[nsmutablearray alloc] init]; (nsstring *path in paths){ filesdictionary =[[nsmutabledictionary alloc] init]; filessize = [[nsnumber alloc] init]; filessize = [filesdictionary objectforkey:nsfilesize]; filesdictionary = [nsdictionary dictionarywithobjectsandkeys:filessize, @"filessize", nil]; [directorycontent addobject:[filesdictionary copy]]; } and using following code bind size in tableview not working. cell.lblsize.text = (nsstring *) [[directorycontent objectatindex:listindex] objectforkey:@"filessize"]; help me convert size of file byte kilobyte , display in tableview. thank in advance..

currently when need share method processparams(params) between different controllers, use either inheritance or services. both solution has inconvenients : with inheritance, cannot use multiple inheritance means need have of controller utility methods in 1 place. , also, there bug in grails not detect code changes in base controller classes in development mode (you need restart app) with services, don't have access injected properties params, session, flush... so question : there other way use common methods accessible multiple controllers ? one option write common methods category, mix controllers necessary. gives lot more flexibility inheritance, has access stuff params, , code simple , understandable. here's tiny example: @category(object) class mycontrollercategory { def printparams() { println params } } @mixin(mycontrollercategory) class somethingcontroller { def create = { printparams() ... } def s

i building windows service listens connections on tcp and, once connection established, sends steady stream of data. simple... once initial request made, communication one-way (on application layer, of course). what way test significant load, 3,000 simultaneous connections? there standard tools kind of thing, or should write own? i have feeling have written own protocol, think you're stuck implementing own load testing client. writing load testing client isn't hard. thing advise though think whether you're going test on connection 1 physical machine or multiple. i'm not saying should test 3,000 physical machines, 10 or 20 machines idea. otherwise have chance client machine being bottleneck. also, test server, have have load test implementation. if see processor usage of load tester staying @ 100%, you're not testing server; you're testing client.

i'm @ wits end trying solve issue. i have function in class such public class receivedata { dataprovider provider = new dataprovider(); public void responsedata() { foreach(string anitem in thelist) { // alldata function declared in class dataprovider string result = provider.alldata(anitem); } //do } } that's simple. however, if alldata function had make async function calls data? meaning, say public class dataprovider { myserviceclient client = new myserviceclient(); public string alldata (string myitem) { client.formatteddatacompleted += new eventhandler<formatteddatacompletedeventargs>(client_formatteddatacompleted); client.formatteddataasync(myitem); } void client_formatteddatacompleted(object sender, formatteddatacompletedeventargs e) { // here's response comes back. } as can see, cant call alldata function , directly
