android - CursorTreeAdapter - Return part of Groupcursor for Childview Data -

-

i'm using cursortreeadapter map curser expandablelistview in android.

everything works fine except way data handled inside listview. data inside cursor give constructor of cursortreeadater - daa childview. problem android expects data childview received getchildrencursor function:

@override protected cursor getchildrencursor(cursor groupcursor) {     db.open();     return db.getepisode(groupcursor.getstring(0)); }

here see problem. have return cursor i'm not able "cut out" 1 entry in cursor responsible specific childview. instead came querying database every single childview there is. not dumb since data there (inside groupcursor) ist pretty slow.

my question if there kind of functionality of cloning specific entries of cursors or returning 1 entry instead of querying database.

maybe i'm off using cursortreeadapter , using more general adapterclass beneficial.

thank all, johannes

i figured our myself.

the answer switch cursortreeadapter baseexpandablelistadapter

i somehow scared before (dunno why) working charm.

if interested in code can post here. leave comment

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.
