delphi - Usage of SHGetSpecialFolderPath to retrieve an application folder that can be accessed also to non admin users, which CSIDL to choose? -

-

in application store on every machine files in application folder.

a simplified version of real case this:

..\project1\loginhistory (login history file - common users) ..\project1\translations (localization files - common users) ..\project1\formsettings\user1\ (this contains ini file per form user1) ..\project1\formsettings\usern\ (this contains ini file per form usern)

so can see why use this: save data specific machine (remember latest logins made machine, kind of mru), store translation strings or 3rd party components (these extracted runtime exe resources) , saving user specific data (like form size). real case more complex, @ least can there "common folder" , "user folders".

now keep structure, files in single ..\project1 folder (+ subfolders). because users not windows users, sql server users.

my question folder choose ..\.

currently (succesfully) using code retrieveing ..\ 

uses shlobj;  function getspecialfolder(const csidl: integer) : string; var   recpath : pwidechar; begin   recpath := stralloc(max_path);     try     fillchar(recpath^, max_path, 0);     if shgetspecialfolderpath(0, recpath, csidl, false)        result := recpath       else result := '';           strdispose(recpath);     end; end;

and call with

getspecialfolder(csidl_appdata)

where list of cdisl defined here.

getspecialfolder(csidl_appdata) returns c:\users\username\appdata\roaming in windows 7.

so used work, recieved complaint customer seems directly related read/write problems in these folders. (for example c:\users\username\appdata\roaming\project1\loginhistory - using folders listed above).

so question is: correct use csidl_appdata? have suggestion? there chance on os or users reduced privileges there can read/write problems on folder?

please remember not have more 1 root folder files.

i think want use csidl_common_appdata files not user-specific. if assumed (in code) files stored in csidl_appdata shared among users, not allowed.

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.
