dllimport - How can I use a DLL from Python -

-

i trying load dll in python, want use econnect() function using ctypes

what know source code of dll:

  • from *.cpp source code: bool econnect( const char *host, uint port, int clientid=0);
  • from dependency walker tool: function ordinal 6 , undecorated name is
    ?econnect@eclientsocket@@uae_npbdih@z

i tried access econnect 2 ways myfunction , myfunction2, wrong. here code:

from ctypes import *  def main():  ip = c_char_p('127.0.0.1') port = c_uint(7496) client_id = c_int(0)  myfunction = getattr(cdll.twssocketclient, "?econnect@eclientsocket@@uae_npbdih@z") myfunction2= cdll.twssocketclient[6]  print myfunction print myfunction2  print myfunction(ip, port, client_id,ip)  if __name__ == "__main__": main()

i below error:

"windowserror: exception: access violation reading 0x0000002d"

i badly need here (i not know c++). thanks!

to make things easier, more pythonic, might want ctypesgen:

http://code.google.com/p/ctypesgen/

it generate proper wrapper functions, data types , such you. if want know how use ctypes, might start tutorial:

http://docs.python.org/library/ctypes.html

anything more specific , i'll have read api dll you're attempting use.

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.
