c++ - Cannot start DirectX 11 executable with Visual Studio, Build works properly -


following directx 11 code, displays window , keeps open waiting messages:

#include "stdafx.h" #include <iostream>  lresult callback windowproc(_in_ hwnd   hwnd, _in_ uint   umsg,     _in_ wparam wparam, _in_ lparam lparam) {     if (umsg == wm_destroy) {         postquitmessage(0);         return 0;     }     return defwindowproc(hwnd, umsg, wparam, lparam); }  // directx main int winapi wwinmain(hinstance hinstance, hinstance previnstance, lpwstr cmd, int ncmdshow) {     wndclassex window;     zeromemory(&window, sizeof(wndclassex));     window.cbsize = sizeof(wndclassex);     window.hbrbackground = (hbrush) color_window;     window.hinstance = hinstance;     window.lpfnwndproc = windowproc;     window.lpszclassname = (lpcwstr)"mainwindow";   // class name     window.style = cs_hredraw | cs_vredraw;      registerclassex(&window);      hwnd windowhandle = createwindow((lpcwstr)"main window", (lpcwstr)"directx tut!", ws_overlappedwindow,         100, 100, 600, 800, null, null, hinstance, 0);      if (!windowhandle)          return -1;      showwindow(windowhandle, ncmdshow);      msg message;     while (getmessage(&message, null, 0, 0))    // continuously loop messages     {         dispatchmessage(&message);     }      return 0; }

stdafx.h precompiled header file in include directx includes. namely in c:\program files (x86)\windows kits\8.1\include\shared;c:\program files (x86)\windows kits\8.1\include\um;

i include c:\program files (x86)\windows kits\8.1\include\shared;c:\program files (x86)\windows kits\8.1\include\um; libraries located in c:\program files (x86)\windows kits\8.1\lib\winv6.3\um\x64

i'm using visual studio 2015, windows 8.1 64bit. followed this tutorial create directx application. made win32 project, done these modifications in include , libs, pasted code , built properly. running not output anything. says build succeeded. vs works other projects. have tried configurations in x64 mode. if had guess i'd not finding dll.. cannot find culprit.

you have specified "mainwindow" it's class name when registering window class when creating window have specified ""main window", windows unable find class. passing "mainwindow" it's class name createwindow fix issue:

window.lpszclassname = l"mainwindow";   // class name window.style = cs_hredraw | cs_vredraw;  registerclassex(&window); hwnd windowhandle = createwindow(l"mainwindow", l"directx tut!", ws_overlappedwindow,     100, 100, 600, 800, null, null, hinstance, 0);

as shown above, should use l prefix wide character string literals

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() .
