directx - Find out which display belongs to which adapter? -

-

i'm working on slimdx apps works multiple display. apps occupy selected display, , it's selection input via commandline, int. use system.windows.forms.screen.allscreens[selection] find out bound, , display apps "fullscreen" on display.

now, optimize performance, need select gpu adapter initialize direct3d's device. how find out gpu adapter powering selected display?

since each gpu adapter might have 1 2 display connected, can't use display number.

i'm utilizing direct3d10. don't mind solution in direct3d9.

worse case let user select display , adapter via commandline, prefer fool prove method.

thanks

both d3d10 , d3d11 use dxgi managing details this. factory interface create lets list of adapters installed on system. each adapter can have 1 or more outputs, can enumerate adapter interface.

this list of output interfaces, have description property contains, among other things, rectangle of output's bounds intptr handle monitor on running.

i don't think winforms screen class exposes underlying native pointer, why provide slimdx.windows.displaymonitor class serve replacement screen class. can use determine particular details of display , choose right adapter needs.

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.
