c# - .NET - WindowStyle = hidden vs. CreateNoWindow = true? -

-

when start new process, difference make if use 

windowstyle = hidden

or 

createnowindow = true

property of processstartinfo class?

as hans said, windowstyle recommendation passed process, application can choose ignore it.

createnowindow controls how console works child process, doesn't work alone.

createnowindow works in conjunction useshellexecute follows:

to run process without window:

processstartinfo info = new processstartinfo(filename, arg);  info.createnowindow = true;  info.useshellexecute = false; process processchild = process.start(info);

to run child process in it's own window (new console)

processstartinfo info = new processstartinfo(filename, arg);  info.useshellexecute = true; // default value. process processchild = process.start(info); // separate window

to run child process in parent's console window

processstartinfo info = new processstartinfo(filename, arg);  info.useshellexecute = false; // causes consoles share window  process processchild = process.start(info);

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.
