coding style - c++ curly braces and comments -


c++ begginer here. i'm struggling bit what's best practice curly braces + //comments.

i see functions comments above definition provide visual studio inspection utility hovering mouse on them anywhere. when comes if statements , sorts, can't figure out best more helpful in upcoming projects

so, between

if (condition) {  // comment     something(); }

or

// comment if (condition) {       something(); }

or

if (condition) // comment {       something(); }

or following 1 (to use useless newline)

if (condition) {  // comment     something(); }

there no clear "ah 1 better because of xyz", me yet.

thank foresight!

cheers

this example may handled differently depending on whether comment applied condition or bock. first case typically indicates condition may rather complex , make sense refactor separate variable or separate method proper naming comment (if still necessary) applied variable or method. second case typically indicates doing complex in block , make sense refactor block separate method proper naming comment (if still necessary again) applied method. notice introduction of separate entities proper names removes need comment.

as curly braces there no common approach, can encounter kind of crazy braces placement. people defend such pluralism. prefer place matching braces aligned - either horizontally (that on same line) or vertically (that same indentation) when content not fit 1 line. , rule applied braces, not curly.

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...

python Tkinter Capturing keyboard events save as one single string -

is possible store keyboard events 1 string? code below stores 1 char , prints it. card reader or bar code reader, contains collection of character/ string not 1 character @ time. goal save char pressed text variable. from tkinter import * root = tk() def key(event): text= event.char text+= event.char print ("pressed", text) def callback(event): frame.focus_set() print ("clicked at", event.x, event.y) frame = frame(root, width=100, height=100) frame.bind("<key>", key) frame.bind("<button-1>", callback) frame.pack() root.mainloop() currently, creating text variable , everytime key() function gets called, , text stores last character typed. you can define text module level variable , , use module level text inside key function - text = '' def key(event): global text text+= event.char print("pressed", text)

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
