eclipse - Android project Refactor greyed out -

-

i renamed project in eclipse via 'refactor > rename' suggested in this answer.

i want rename again, refactor menu has only one menu item (android > extract android string...) greyed out!

i using eclipse 3.6.1 latest android sdk 9.

why , how restore normal?

update (1): after following sankar ganesh's suggestion (selecting string), refactor menu appeared again. selected rename... menu item again , received following error message box:

this better previous situation, in had no idea why refactor menu had been disabled , do. still, don't understand why , rules should follow when using refactor function. wanted rename project... that's all. :)

update (2): tried same exact operation again again (refactor > rename while project selected in project explorer) , worked! (without issuing message box shown above).

what's going on?

must bug, because inconsistent.

i wonder,why struggling renaming project, if want rename project, can select project, click refactor menu, rename, that's it

step1:

step2: see project name updated,initally friend finder, friendfinderupdated

also , can use extract android string valid java identifiers , not packages , files, because see window here

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.
