c++ - Visual Studio need to rebuild solution for every change -


i working on game engine in c++. have progressed further project, have noticed resulting executable not reflect latest code changes. cleaning solution , rebuilding it, fixes problem. unfortunately complete rebuild not viable option larger code base anymore.

i have checked different solutions on stackoverflow:

  • i have checked "build , run" setting set "always build"
  • the configuration manager set "build"

additional information:

  • it opengl project glfw , glad in c++
  • i use visual studio community 2017 version 15.2

this annoying issue causes lot of productivity loss, since have rebuild entire solution every time want see change. grateful input. please ask if more information required.

i don't know if of relevance, when making small change testscene.cpp , rerunning code: enter image description here

update

here in depth explanation of issue:

  1. i have class allows rotate object transformerscript.cpp
  2. i have set rotation speed 1.
  3. the object rotates expected.

enter image description here

  1. now change speed float value 1 0.
  2. i press run (local windows debugger)
  3. this output log:

========== build: 1 succeeded, 0 failed, 0 up-to-date, 0 skipped ==========

  1. the compiled executable starts
  2. the result same figure rotating @ same speed.
  3. expected behavior: no rotation, since float set 0.
  4. i forced "clean solution" , "rebuild solution"
  5. this takes 1 2 minutes on laptop
  6. vs finishes rebuilding new solution
  7. i press run (local windows debugger)
  8. the object not moving. (this expected)

alternative approach

  1. set break point @ position of speed float value
  2. i press run (local windows debugger)
  3. sometimes (90% of cases) error prompt pops up. other times (10% of cases) works expected

enter image description here

  1. i press ok
  2. the compiled executable starts
  3. the result same figure rotating @ same speed.
  4. expected behavior: no rotation, since float set 0.
  5. the break point not triggered!

if changes in header file need full rebuild changes reflected think.

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() .
