c# - Pass WPF textbox.text from Window1 to data class -

-

i have wpf window collects data , sends data class saved xml file. want name file in textbox on window1 form , pass data class file can saved. know have let data class know window1 exists, i'm having trouble syntax - guess.

you should try other way around: view (wpf) should know view model (wrapper) knows how collect data, should used save file. vm should know model (the implementation of file save stuff among other models data sources etc.) , feed necessary information.

using approach combined nootification, can swap out several parts without affecting others.

  • the model (back end) independant of else.
  • the view can defined elsewhere , shouldn't use code behind (except definition of vm , events). binds vm.
  • the view model puts together. provides data structure, can used , presented in wpf. through binding vm informs wpf of updates etc.

in case:

  • design nice gui
  • design vm can collect necessary information.
  • write method takes parameters required file.
  • in event or command handler (click etc.) call vm method passes collected info file method.

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.
