c# - How to use GetPropertyValueSafely from CommonLibrary.NET? -


when using commonlibrary.net, how 1 use getpropertyvaluesafely() function correctly?

i want this:

public static string app_title = comlib.reflectionhelper.getpropertyvaluesafely(application.productname);

but need add second parameter, , don't understand enough yet know asked for. here syntax usage documentation file:

public static object getpropertyvaluesafely(     object obj,     propertyinfo propinfo )

this parameter requirements:

parameters obj type: system..::..object object property retrieved.

propinfo type: system.reflection..::..propertyinfo property name.

so put object? tried this, too:

public static string app_title; comlib.reflectionhelper.getpropertyvaluesafely(app_title, application.productname);

but that's not answer either.

i tried this:

public static string app_title = comlib.reflection.reflectionutils.getpropertyvalue((object)app_title, application.productname).tostring();

...which compiles, throws runtime type error library.

thanks (i'm starting stuff head).

try this:

public static readonly string app_title = (string)comlib.reflectionhelper.getpropertyvaluesafely(new object(),      comlib.reflection.reflectionutils.getproperty(typeof(application), "productname"));

nb: technically, passing new object() propertyinfo's getvalue method should throw targetexception. however, since static property, seems work.

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).

i'm using named queries fetch entities database using jpa , hibernate , came across puzzling me: how come there no default implementations of javax.persistence.parameter interface? i rather impressed how @staticmetamodel used criteriabuilder in jpa2 meaning type safety , don't have mess around setting string names. wanted apply similar of jpa1 ejb's i'm working on: dealergroup_.class: public dealergroup_ { public parameter<integer> id = new parameterimpl<integer>("id"); /// etc... } dealergroupfacade.class: // ... public dealergroup fetch(integer id) { typedquery<dealergroup> query = em.createnamedquery("dealergroup.fetchbyid", dealergroup.class); query.setparameter(dealergroup_.id, query); return query.getsingleresult(); } // ... i surprised find there no implementations of parameter interface - of course, implement myself absence makes me suspicious may mistake using in way? should implementing parameter...
