c++ - relative path problem for a deployed win32 application -

-

i have written c++ program , deployed in c:\my_app, , executable's path c:\my_app\my_app.exe. say, my_app needs many files such the_file.txt, located in c:\my_app\the_file.txt.

in executable, open txt file as, xx.open("the_file.txt");

moreover, have associated program let's .myp extension.

when i'm on desktop, , want open file named example.myp, program can not see the_file.txt. because, (somehow) assumes it's working on desktop.

is there easy way handle problem changing shell command open in hkey_classes_root? naive solution change file open operations "%my_app_location/the_file.txt". don't want that.

thanks help.

always use full path name open file. in other words, don't open "foo.txt", open "c:\bar\foo.txt". find install directory of exe use getmodulefilename(), passing null module handle.

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.
