what conditions test real purchases, when have tested app using test product android.test.purchased ? there few steps need pass, remembering, of them need time update on google play servers. for example, let's use com.example.product our real product id. time shows in example change own. upload apk file you can't test real purchases in debug mode. need download app beta, google know it's ok make purchases in app. check if have billing permission in androidmanifest.xml : <uses-permission android:name="com.android.vending.billing" /> change android.test.purchased com.example.product , export *.apk file. must signed ! publish apk in beta, you can go next steps, you'd need time beta ready download. add new product you can't add new product until have published beta. you can't test subscriptions, products. can test subscriptions (they renewed every 24h) go products section in google play develop

wondering if there time based synchronization in java. example below synchronization locks object , waits until //my application processor finishes task. synchronize (myobject) { //my application processor. } with same, there way synchronize 1 min or 2 min. synchronize (only 1 min && object) { //my application processor } or there other way in java synchronization method. p.s: don't want run threadmanager monitor above. , don't want run while loop. maybe looking java.util.concurrent.scheduledthreadpoolexecutor provides various ways of scheduling task performed/repeated in thread @ specified time/times in future. maybe have method holds lock extended period of time (almost bad idea), , asking how abort operation , release lock if time limit reached. there couple of ways depending on takes time. but guesses. haven't told problem trying solve. your example of using "synchronized" timeout not make sense. purpose of &q

i need efficient way cast part of array variable. let's suppose array defined this: unsigned char bytes[240]; now, need uint32_t value somewhere in array, this: uint32_t * word = reinterpret_cast<uint32_t *>(bytes[4]); which think me second word in array right? question is, safe , portable (windows, linux on x86 & x86_64, os x nice, don't care arm, ia-64 etc). you should use memcpy . portably ensures there no alignment or strict aliasing problems. if no copy needed, compilers smart enough figure out , directly reference data in array: uint32_t value; memcpy(&value, &bytes[4], sizeof value); //modify value: //... //copy array: memcpy(&bytes[4], &value, sizeof value);

as title says, have simple loop cumulative variable += value of calculation. however, after each iteration, variable being reset zero. why? here's loop: int score_board(board* b) { int i; int total_score = 0; for(i = 0; < 4; i++) { printf("current total = %d\n",total_score); total_score += score_line(grab_line(b, i, 0)); total_score += score_line(grab_line(b, i, 1)); printf("scored row , columnn %d\tcum total=%d\n", i, total_score); } return total_score; } and here's output i'm getting, proving while total_score set value want during 1 iteration, loses value upon resetting loop: current total = 0 line score = 11000 line score = 40000 scored row , columnn 0 cum total=51000 current total = 0 line score = 60000 line score = 50000 scored row , columnn 1 cum total=110000 current total = 0 line score = 20000 line score = 40000 scored row , columnn 2 cum total=60000 cu

i'm using 2013 q3 telerik tab control in c# winforms project. if test .visible property of control placed on page in tab return false unless select page. there property besides .visible can used test visibility of control on page without having select it? here's dilatation: should not change native meaning of control's properties. period. asked in comment trying achieve, because suspected you're basing ui logic on control's visibility, in opinion isn't approach. visibility should bound background logic, not oposite. you're hiding controls reason, because @ point happened - keep track of "something" instead of inspecting results. imo visibility property should set, never checked. alternatively if it's not possible change concept reason, workaround i'd attach handler visiblechanged event , set enabled property if sender not tab control - checking against enabled property you'd know whether control in use or not. find

i'm asking on how show html code on tutorial html website, example show user how make link? <a href="#">text</a> thanks in advance with cdatasection. cdatasection object represents cdata section in document. a cdata section contains text not parsed parser. tags inside cdata section not treated markup , entities not expanded. you can use in xml sample : <![cdata[<tag>some text</tag>]]> it interpreted such : &lt;tag&gt;some text&lt;/tag&gt; or in program output. sample css : <style type="text/css"> /*<![cdata[*/ body { background:black; } /*]]>*/ </style> hope you.

i understand how can invoke through bpel stored procedure in non-blocking way. concern have stored procedure (in dbadpater) i'm invoking, takes time (around 30 minutes) , cannot wait until finishes. i'm trying setting in composite application invoke property "nonblockinginvoke" doesn't work, adapter blocking until respsonse. thanks. nonblockinginvoke use in flow when want separate thread of execution sync invoke branch, doesn't block other flows. flow cooperative parallel - not true parallel. sync invoke still blocks during call. read more here . anyway, 1 solution problem have new composite calls async composite uses db adapter execute stored proc. so, new service calls other service async, won't block - service calling db adapter blocks, @ point, invoker free. it's not bad idea wrap db adapter calls in own composite decouple/isolate true service implementation db service interface - can cahange.

first of all, using user defined function called showbin() print binary of integer.as can see function checks each bit of given number right position left position(msb lsb). am using union 2 members, have stored 512 in first member (short unsigned int a) ,( we know normally(in big endian) binary of 512 0000 0010 0000 0000 ) , in next step tried print values of array c[0] , c[1] machine little endian it outputs : 0 2 ,now means under hood(in memory) binary stored as: 0000 0000 0000 0010 but when print value of a using showbin() shows 0000 0010 0000 0000 in normal(big endian) way, why not output in little endian way i,e 0000 0000 0000 0010 ???? .even if computer stores number in big endian should output 2 0 right?? ???? confused..????..can 1 please explain behavior in simple words. void showbin(unsigned short int a); int main() { union myun { short unsigned int a; //2 bytes char c[2]; //2 bytes }; union myun som; som.a=512; pr

on google maps' js api reference page , says method getmaxzoomatlatlng : returns maximum zoom level available @ particular latlng satellite map type. for reason, terrain maptype bottoms out @ level 15 in calgary (for example) satellite maptype can go way zoom 19 . have 2 map services running simulataneously, , want maps in sync, can't sync if can't reach same zoom level. so, i want know when terrain map (or maptype) can't cope, , trigger special case functions. is there method, or alternative, getting maximum zoom location specific map type (since above mentioned method works satellite)? well, 1 solution i've decided go in meantime attach zoom-end handler arcgis map (could leaflet well) , maptypeid_changed handler google map. so, arcgis map ( emap ) did this: emap.on('zoom-end', function (e) { // map zooms synced gmap.setcenter(esri.geometry.webmercatortogeographic(e.extent.getcenter())); gmap.setzoom(e.level);

i trying this, not working. there way of doing differently? if($("#user_password").keypress()){ alert("hello"); } user_password id of textbox on login screen. i have canceled event textboxes when push enter, want allow them press enter in password field on login page. complete code is: $(document).keypress(function (e) { if($("#user_password").keypress()){ alert("hello"); } if(e.which == 13 && e.target.nodename != "textarea") return false; }); you need set event handler, if statements aren't relevant here: $("#user_password").keypress(function () { alert("hello"); }); if want find out element triggered event, @ event's target property: $(document).keypress(function (e) { if (e.target == $("#user_password")[0]) alert("hello"); if(e.which == 13 && e.target.nodename != "textarea") return false; });
