c# - what to look out for when migrating .net apps to Windows 7, 64 bit -

-

we migrating our desktop windows 7, 64 bit (from 32bit windows xp). have number of winforms c# applications , trying figure out out in upgrade. there suggestions or resources @ developer point of view on out make smooth transition?

.net behaves more or less same on 32bit , 64bit os'es, there not worry there afaik.

the main things must aware of changes in os itself:

  • the registry changed, if read or write registry settings may have modify code
  • some file locations changed. have program files 64-bit apps , program files (x86) 32-bit apps instance. other system folders have moved.
  • uac may cause trouble. must test this
  • your program may not have rights write locations on file system or in registry. may have ask user permission or require user run application administrator in worst case.

those changes can think of @ moment. in cases app run fine on both os'es.

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.
