.net - Best approach to send mass e-mails through an ASP.NET webpage -

-

i've written contact management/communication system records details of people , allows mass communications sent out.

however when e-mails being sent following exception raised:

system.threading.threadabortexception: thread being aborted

what best way send out mass e-mails through asp.net?

what i'm looking approach that'll keep in asp.net

i have feeling may need store e-mails in database , have separate .net console application/windows service send them out. because of development overhead , lack of time have, last option want consider.

there no reliable way mass email broadcasting .net without intermediary.

what mean emails must queued in database or other persisted storage. then, need app (console, service, whatever) responsible monitoring queue , acting on broadcast requests.

second, not send them straight code. instead, send emails local mail server under control rebroadcasting actual recipient. shear number of spam detection mechanisms (like grey-listing) means spend inordinate amount of time doing things sending message, getting grey-list denial, waiting 15 minutes (or long), sending again see go through.

the reason queueing if going through real mail server keep overloading local mail server.

sending mail .net fine 1 offs, when of recipients within company. however, anytime have send them general public reliability need "grow up" speak.

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.
