first time working hud , i'm confused. i setup hud in viewdidload: [mbprogresshud showhudaddedto:self.view animated:yes]; dispatch_async(dispatch_get_global_queue( dispatch_queue_priority_low, 0), ^{ [[[wsxmppusermanager shared] xmppstreammanager] connect]; dispatch_async(dispatch_get_main_queue(), ^{ [mbprogresshud hidehudforview:self.view animated:yes]; }); }); the hud doesn't show. think reason follows. xmpp connect method fires off connection request xmpp server , it's done. there no activity wait is. however, connection isn't established until server responds , following delegate method fired: - (void)xmppstreamdidauthenticate:(xmppstream *)sender i want wait , dismiss hud, i'm @ loss how that. i'm missing simple. you need move code dispatch_async(dispatch_get_main_queue(), ^{ [mbprogresshud hidehudforview:self.view animated:yes]; }); after long running method has finished... is, if code indeed returnin...

can run loop (while, for, dowhile etc) in callback function. here sample code : var execute = function (data,callback) { //do data callback(); } execute (data,function(error,returndataarray) { var boo = true; while(boo) { //do returndataarray if (returndataarray.length == 10) boo=false; } }); now, doubt is, main node.js thread wait until above while loop executed? your main thread blocked looping occuring inside callback function. that's because callback functions delayed until completion, , then, they're pushed javascript event loop , executed once thread free. in simpler word, in node (and javascript) happen in single thread (normal execution, callback, timeouts, etc). the way execute function thread javascript manually pushing thread. in browser that'll web worker, , on node cluster.

i'm trying create multi-tenant application shared schema.we have identified discriminator field filter out data base on customers. i'm facing problem in tablegenerator strategy generating primary keys of entities. as per logic have 2 columns seq_name , another(seq_count) tracking count. but since multitenant application need keep them separate each customer. multiple customers have seq_name & seq_count columns belong them respectively. i thinking might have write custom logic tablegenerator attribute discriminator column, before need advice other way this?

as cannot write extension method objects in vb.net, can write method converting other type , use object? i assume you're trying around this issue . note not can't write extension methods object , can't use them on object variables or expressions because has cater late-bound calls. if knew object other type cast , use extension method (including method extending object , of course).

when create gridview in asp.net, set control id "factorytable", in browser html code, id turn "contentplaceholder1_factorytable" can delete "contentplaceholder1_" or modify other name? just add attribute clientidmode="static" to gridview markup. example: <asp:textbox id="txtecho2" runat="server" width="65%" clientidmode="static" /> example output: <input id="txtecho2" style="width: 65%" name="ctl00$masterpagebody$ctl00$txtecho2" /> see here different modes: http://weblogs.asp.net/asptest/archive/2009/01/06/asp-net-4-0-clientid-overview.aspx

i looking @ this example, , raises queston me: when looking @ this file mutex being used when accessing global variable m_abort when being changed. when run method reads it, nothing mutex @ all. why? well, cannot see purpose of mutex @ all. both reading , writing m_abort can performed without mutex protection it's bool variable, , value changed atomically (at least on platforms). , if write not atomic , variable can have inconsistent value - can either false or true, , read true (since value written there true ).

i need insert basic block edge. tried use splitedge method in following link: http://llvm.org/docs/doxygen/html/basicblockutils_8cpp_source.html found answer here: http://lists.cs.uiuc.edu/pipermail/llvmdev/2010-july/033288.html but, don't want set in runonfunction,, how use without facing problem of pass not equal null thanks i think simplest way copy implementation of splitedge method own code , modify them work when pass null. in current implementation, means modify call own version of splitblock , , in version add return new before calls on p . however, if these sorts of operations on llvm ir, consider doing them within proper pass - make code play far more nicely existing passes.

since stuck on problem , don't know mistake need ask guys. when first launch app works fine, when press "back" button on phone main screen , start app again (which not real new startup because app goes sleep) has strange behaviour. i using opengles draw texture onto screen , when make touch texture changes. touch sets boolean true indicates draw other texture. somehow false when test value when got written true touch event. wondering because happens when pressed "back" button on phone. when returning main screen home button , moving app thing doesnt occur , works. first thought threads 2 different threads(activity rendering thread , surfaceview thread touch events) when synchronizing get/set methods still doesnt work. starting think touch thread thing still operating on old objects , changes values there while references in rendering thread newly instanciated boolean set touch rendering thread takes default value because got different objects somehow not...
