.net - VB.Net socket communication, unusual data being received -

-

i trying communicate local as3 air app on pc via sockets. vb.net app acting server in case while air app client.

the .net app sends data every 25ms air app. have not send message termination. receive data on air app , process it.

on receiving side when debug data see that transitions have been concated.

something if send "abcdef" successively cases receive "abcdef" in cases receive "abcdefabcdef"

is possible underlying tcp network combining data , sending 1 packet. need send message terminator instance "abcdef$" , split messages @ receiving end?

am goofing big time?

from documentation socket.send:

there no guarantee data send appear on network immediately. increase network efficiency, underlying system may delay transmission until significant amount of outgoing data collected. successful completion of send method means underlying system has had room buffer data network send.

there's no guarantee you'll receive complete message @ receiving end either - how sockets work. i'd suggest adding "end of message" marker, , looping in receive code until receive complete message - may receive buffer straddles 2 messages, when you've got "end of message" marker, need keep hold of data received after point, use in reconstructing next message.

i.e. imagine have 2 messages receive - "aaaaaa" , "bbbbbbbb". might receive following 3 separate calls receive (after adding $ end of message marker):

aaaa aaaa$bb bbbbbb$

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.
