java - Installing and running ZeroMQ -


i trying install zeromq on pc can not make program run without crashing.
installation:

1) install visual studio 2017.  2) clone git jzmq , libzmq  3) install zmq version 4.0.4 windows.  4) run script build in: \libzmq\builds\msvc\build\build.bat  5) open in visual studio 2017: libzmq\builds\msvc\vs2017\libzmq.sln , jzmq\jzmq-jni\builds\msvc\msvc.sln.  6) rebuild in visual studio 2017 sln files:  + libzmq.sln : in properties: configuration: active(debugdll) platform: active(x64)  + msvc.sln : in properties: configuration:release platform: active(x64) label vc++ directories: update include directories , library directories, label linker -> input: update additional dependencies - c:\git-repo\libzmq\bin\x64\debug\v141\dynamic\libzmq.lib;%(additionaldependencies)  7) put libzmq.dll , jzmq.dll in system32 folder.

after finished installation, try run simple java example see if working:
java code:

import org.zeromq.zmq; import java.nio.charset.charset;  public class testmainclass {  public static void main(string[] args){     try {         zmq.context context = zmq.context(1);         zmq.socket replier = context.socket(zmq.rep);         replier.bind("tcp://*:5559");          while (true) {              string gwsource = replier.recvstr(charset.defaultcharset());             replier.send("ok");             system.out.println(gwsource);         }     }catch (throwable e) {         system.out.println(e);     }   } } 
import org.zeromq.zmq;  public class requester {  public static void main(string[] args){     zmq.context context = zmq.context(1);     zmq.socket replier = context.socket(zmq.req);     replier.connect("tcp://localhost:5559");      while (true) {         replier.send("public");         system.out.println(new string(replier.recv()));     }   } } 
    <?xml version="1.0" encoding="utf-8"?>     <project xmlns="http://maven.apache.org/pom/4.0.0"      xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"      xsi:schemalocation="http://maven.apache.org/pom/4.0.0    http://maven.apache.org/xsd/maven-4.0.0.xsd">  <modelversion>4.0.0</modelversion>  <groupid>com.test.hagar</groupid> <artifactid>hagartestrealtick</artifactid> <version>current-snapshot</version>  <dependencies>     <dependency>         <groupid>org.zeromq</groupid>         <artifactid>jzmq</artifactid>         <version>3.1.0</version>     </dependency> </dependencies>  </project>

the consul output:

for testmainclass :

the program crash after testmainclass try receive response , print: process finished exit code -1073740791 (0xc0000409)

i think wrong in installation causes fail, can not find problem.

ok, alea acta est:

how debugging root-cause?

level 0: send first int-s, instead of string-s ( having different add-on charset-issues )

level 1: try non-blocking mode of .recv() method ( return non-blocking mode of .recv() method call prove zeromq-part not problem )

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() .
