c# - What am I compromising by running my application as 32 bit in a 64 bit OS Machine -

-

we moved windows xp windows 7. found 1 part of application in c# try create dbf file pda failed thorwing error message "the 'microsoft.ace.oledb.12.0' provider not registered on local machine."

i found many forums pointing me build exe 32 bit here.

my question no. 1) there other driver accessing dbf on 64 bit os machine? (i know there 1 accessing excel , access db). there dbf?

question no 2. same title. have feeling converting 32 bit, not making use of full advantage of 64 bit. losing workaround?

thanks in advance.

x64 processes have access more instructions , more registers. compiling x86 vs cpu give ability jit compiler use instructions , registers (and more memory), typically resulting in (small) performance penalty. really, 99 times out of hundred users won't notice.

what notice program doesn't work if compile cpu because there no 64bit ole driver dbf files. format not used more, , wouldn't surprise me learn microsoft has not written , has no plans build 64bit version.

Javascript line number mapping -

magically formatted comments change reported line number of javascript errors in browsers; this: //@line n "f" n line number , f file name. unfortunately, //@line appears ungoogleable. know there documentation on feature, , browsers support it? (i found references here , here .) from can find available in mozilla based browsers. it using js_setoptions command can turn these options on or off depending on values passed. https://developer.mozilla.org/en/js_setoptions

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.
