hello here attach image have create tableview image . description: in tableview have 2 columns first time , second event show come web services. don't have idea how create type of view . if know example please share me . have find lots of grid view example problem in grid view both column equal have create first(time) columns height depend on second column(event) height equal please share valuable knowledge . thankyou as k6sandeep suggests, can put 2 table-view controllers next each other. assuming data available when loading table views, can count amount of events in time-slot , use value size rows in left column (in heightforrowatindexpath). populate events table usual. using uiscrollview delegate methods (scrollviewdidscroll) of tableviews can synchronise scrolling behaviour. an alternative have collectionview instead of tableviews.

i picked async/await, , wrote series of async methods each perform database sql task , tied each 1 different button. gui doesn't locked when click button, figure that's awesome. however, if click each 1 desired result second button wait first task finish, , on. however, async/await if click multiple buttons i'm not guaranteed finish first. can create unwanted race conditions cause sql queries fail. is there class/object/keyword or can use instead of having each async method handle individual sql command instead adds queue , somehow queue processed serially when has been added it? there many possible designs this. prefer tpl dataflow. you can use actionblock , post async delegates processed sequentially: actionblock<func<task>> _block = new actionblock<func<task>>(action => action()); block.post(async () => { await task.delay(1000); messagebox.show("bar"); }); another possible solution asynchronous

i know difference between const , constexpr. 1 compile time constant , other either compile time or runtime constant. however, array of chars/strings, i'm confused why compiler complains 1 being used on other. for example have: constexpr char* a[2] = {"....", "....."}; const constexpr char* b[2] = {"....", "....."}; with declaration "a" get: iso c++ forbids converting string constant 'char*' [-wwrite-strings] but declaration "b" no warnings. why const qualifier rid of warning? aren't both of them "const char*" anyway? ask because both declared constexpr should make const char* default? i'd expect fine :s const tells compiler chars pointing should not written to. constexpr tells compiler pointers storing in arrays can totally evaluated @ compile time. however, doesn't whether chars pointers pointing might change. by way, way write code be: const char * c

i'd iterate on days in month, so: require 'time' time.now.month # => 5 time.now.day.next # => 32 what mean? 32nd of may? also, rota.rb:2:in `<main>': undefined method `days_in_month' time:class (nomethoderror) what's wrong? this should explain it: time.now.day.class => fixnum fixnum doesn't know dates, have method next . if want advance next day then: (time.now + (60 * 60 * 24)).day => 1 or if have rails installed can do: require 'active_support/time' (time.now + 1.day).day => 1

i have line contains checkbox , text. this: @html.checkbox("cb1") @: checkbox , , requirement is: when hover "my checkbox" , checkbox cb1 hovered. when click "my checkbox" , cb1 clicked. i have tried this, doesn't work: <tr> <td>@html.checkbox("cb1")</td> <td><label id="text">my checkbox</label></td> </tr> with css: #text:hover #cb1:hover { /* mean: if #text hovered, #cb1 hovered too. doesn't work */ } can me? you don't need css. set for attribute in <label> id of control identifies.

so part of upload file setting name of file struggling append time stamp onto file name or set random string or both? here setting file name , type: if ( move_uploaded_file($_files['upload']['tmp_name'], "../uploads/{$_files['upload']['name']}")){ print_r($_files); echo '<p><em>the file has been uploaded</em></p>'; } // end of move.... if. adding timestamp idea. do: $date = new datetime(); if (move_uploaded_file($_files['upload']['tmp_name'], "../uploads/" . $date->gettimestamp() . "_{$_files['upload']['name']}")){ print_r($_files); echo '<p><em>the file has been uploaded</em></p>'; } note have added underscore _ after timestamp becomes easier remove timestamp if need initial filename again: substr($filename, strpos($filename, '_&
