.net - Testing WCF Chat application in different machines -

-

i have solution containing service 2 clients. can communicate each other, send message, , fire events. work fine when test 1 machine, install them on different machines, internet connected , not find each other. since self-hosting service reason? use duallhttpbinding binding configuration. situation chat application 2 client instances , 1 service, each of running on different machines without having network connection other internet connections.

dualhttpbinding requires 2 clients able open connections , send messages each other. either 1 of clients behind firewall can't accept incoming connections, nat router isn't port forwarded, or other client doesn't have correct address find it.

this kind of direct two-way communication on http difficult right once onto internet. debug it, i'd suggest taking @ fiddler excellent http debugging tool. you'll have watch connections , see if clients can connect, , if not, why it's failing. you'll have fix connection problems causing that.

i'm not sure if possible you, less error-prone use net.tcp binding , have server somewhere clients can connect (as net.tcp doesn't require server able open port client, can send using existing connection). requires client able connect server, rather server needing able create second connection client, , works through standard nat configurations.

c# - Is it possible to remove an existing registration from Autofac container builder? -

-
something along lines: builder.registertype<mytype>().as<itype>(); builder.registertype<mytype2>().as<itype>(); builder.deregistertype<mytype>().as<itype>() var container = builder.build(); var types = container.resolve<ienumerable<itype>>(); assert.istrue(types.count == 1); assert.istrue(types[0].gettype == typeof(mytype2)); scenario: go through bunch of assemblies , go register types want make sure have 1 implementation of given type. need before create container. track on own nice if autofac me bit. this cannot done directly using containerbuilder , unless start on new one. mind you, having first built container should able construct new container filtering away unwanted types , reusing registrations first container. this: ... var container = builder.build(); builder = new containerbuilder(); var components = container.componentregistry.registrations .where(cr => cr.activator.limittype != typ...

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
