c# - .NET: Windows forms/controls performance -

-

we have application heavy ui. our clients started complaining application startup performance. (previously our controls/forms initialized while kind of splash screen message 'starting' shown).

i've made research , found control's initializecomponent() (which generated vs designer) method call can take ~0.4-0.5s complex controls. , there lot of such controls, i'm getting ~10-15 seconds of application startup time result. there nothing heavy there, controls initialization (for example, different toolstrips, toolstripbuttons, menustrips initialization, setup of different texts etc).

is there way improve performance of controls initialization in case? maybe kind of caching or smth (so our application start during first load)?

p.s. we're using .net 2.0

thanks in advance.

you indicate you've performed @ least rudimentary analysis of app's start-up time, have thoroughly profiled app using visual studio's profiler, ants or similar?

thoroughly profiling of app give accurate break-down of app spends time. less , you're guessing.

you might consider ngen'ing portions of app , re-profiling app's start-up times determine whether ngenning of code delivered performance boost.

however, if you've built that's complex, may asking of users' machines. why it's vital measure performance of code on tin that's similar possible end-users' hardware , environment.

another thing consider winforms doesn't take advantage of modern-day hardware accelerated graphics. may find porting wpf gives boost need, sure prototype , profile before committing significant resources path.

hth.

i trying send mail linux command line using mailx command. can send local domain no problem want set mail send gmail account receive mail sent gmail account. after configuring mail.rc so: account gmail { set smtp=smtps://smtp.gmail.com:587 set smtp-auth=login set smtp-auth-user=username@gmail.com set smtp-auth-password=password set ssl-verify=ignore } i error: resolving host smtp.gmail.com . . . done. connecting 74.125.25.109 . . . connected. missing "nss-config-dir" variable.

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.
