winapi - escaping string on Windows command line -

-

i'm trying pass string win32 program command line printed without changes.

why have escape
"aaa <bbb@pobox.com>" """aaa <bbb@pobox.com>"""
but
"aaa <bbb@pobox.com>", (comma included) "\"aaa ^<bbb@pobox.com^>\","

i see no consistency in escaping rules windows command line

p.s. i'm trying generate .cmd file

update:

i'm using simple c program testing compiled gcc, no additional object files linked. if replace perl, rules remain same.

i'm trying create general escaping algorithm. generate .cmd file call perl output redirect. have problem if string contains odd number of double quotes escaped backslash, output redirect not function. same problem described in last comment http://blogs.msdn.com/b/oldnewthing/archive/2010/09/17/10063629.aspx .

if use "" escape ", splits on space, result 2 parameters instead of one. "" has artifacts.

in windows there no 1 way of getting command line , parsing it. programs have been left deal themselves.

there recent post raymond chen commandlinetoargvw function mentions various rules quoting they'll apply if program uses particular function. http://blogs.msdn.com/b/oldnewthing/archive/2010/09/17/10063629.aspx

in windows command line passed program unmolested (i.e. no wildcards expanded) , program needs deal it. programming language may provide convenience default argument parsing, , might use standard windows function commandlinetoargvw program opt read unadulterated string thereby skipping standards.

this means need figure out rules particular program trying script , use them.

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.
