visual studio - VS10 always rebuilding because .ILK is slightly newer than .PDB -


i've got project vs10 thinks out of date. can press [f7] , see build finish without errors, wait minute, press [f7] again , have relink. if try run or debug, warns me project out of date.

based on accepted answer here able capture debug output devenv.exe , isolate reason wants rebuild:

[5392] project 'q:\swdev\x\tests\x.y.z\src\x.y.z.vcxproj' not date because 'q:\swdev\x\tests\x.y.z\bin\x64\win32\checked\x.y.z.ilk' modified @ 08/15/2017 03:32:38, newer 'q:\swdev\x\tests\x.y.z\bin\x64\win32\checked\x.y.z.pdb' modified @ 08/15/2017 07:32:36.

i'm not sure why second time shown in utc , first in local time, don't think that's problem, because claim of newer appears correctly reflect actual time relation.

when check files manually, .ilk file indeed modified @ 3:32:38, 2 seconds later .pdb, modified @ ‏‎3:32:36.

the answer this question looked promising, unlike in problem, cl , link settings have separate pdb files, c/c++ set $(intdir)vc$(platformtoolsetversion).pdb , linker set $(targetdir)$(targetname).pdb. double-check, have bin\x64\win32\checked\obj\vc100.pdb file modified ‏‎3:29:42.

i've seen suggestions in various places 'always rebuilds' problems may due upgrading prior vs. wasn't case project (although depends on library was upgraded vs9 , doesn't have problem.) in fact, have deleted source code , recreated solution , project scratch , problem persists.

all development files on network shares exposed oracle solaris' cifs, server being used many, many other things including projects in other versions of visual studio (9 , 12) without issue.

i'm confused why configured depend on .ilk file. afaik file contain internal data linker uses incremental linking, 1. wouldn't expect meaningfully change unless actual linker inputs change , 2. emitted around same time .pdb, think makes no sense test file.

i don't know enough msbuild system know making check or how stop it.

as workaround, have turned off incremental linking, , makes problem go away, know if there proper solution. project, not using incremental linking inconsequential, others become issue.

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() .
