Socket servers, SocketAsyncEventArgs and concurrent connections in .Net -

-

i've been writing socket server based around 1 on codeproject derives original microsoft example.

in both cases, inbound message returned sender using same socketasynceventargs. in case, need send inbound message off further async processing prior replying client.

the problem returning response may try use same socketasynceventargs @ same time further message client. when happens exception:

"an asynchronous socket operation in progress using socketasynceventargs instance"

so, (i believe) need separate pool of socketasynceventargs messages going out. understandable far.

my problem i'm not sure how create outbound socketasynceventargs relates closely inbound one.

how of inbound 1 can reuse? e.g. if point @ same acceptsocket, there trouble while messages travel in both directions simultaneously?

does have example code of how derive outbound socketasynceventargs inbound one? or missing point?

these socketasynceventargs objects, can use them please. serve you. , socket , buffer use.

so, having codeproject article example, makes sense reuse same saea instance sendasync() right after whole receive (possibly made of several receiveasync() calls) has completed. author states protocol is: each 1 of parties involved send , receive in turns.

in case, simplest release saea instance pool after whole receive completes. then, later on, after finished message processing, can issue brand new send operation using freshly popped pool socketasynceventargs object.

another option keep passing saea used receive operation callback callback during asynchronous processing, , use sending processed message.

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.
