Twitter oAuth login cancel? -

-

i use twitter login in application. if user login, works fine. need handle, when user click cancel button in twitter oauth login screen instead of login. there callback mechanism when user click cancel button?

for web application, if redirect user twitter authorization , user clicks on deny, he/she has option go application or not.

if user didn't log in twitter account, or closed tab or went different url. won't know, unless keep track of users , check if he/she gone longer specified time.

authorization denied

in case, if user clicks on ublogthis! link, he/she redirected application via callbackurl specified when getting request token and! http variable denied included:

http://domain.com/twitterapp/callback.php?denied=8l74y149ftnzi1m3idstring

so then, got out $_get['denied'] if using php example.

if instead open popup window show user twitter authorization page via javascript, can check if popup closed without callback url being initiated. can add timer judge if user went way.

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.
