wix - Heat Harvest Tool Component ID duplication for registry files -


i'm running heat harvest tool multiple registry files (45) have on loop generate wxs file.

it works except 3 files same component id generated.

heat reg myreg.reg -cg compoentgroup -gg -o myreg.reg.wxs heat reg myreg1.reg -cg compoentgroup1 -gg -o myreg1.reg.wxs heat reg myreg2.reg -cg compoentgroup2 -gg -o myreg2.reg.wxs

result in same component id 

<component id="cmp0278c3ef60ddfa362d50d5dd0254bcb9" directory="targetdir" guid="{eed2941a-01bd-4ce5-97bf-75f19b6605a6}" keypath="yes">

though guid unique.

i wonder how can avoid situation or alternate way of doing same.

the component/@id should based on full "path" of contained registry key. so, if have 2 registry keys in .reg files (that may or may not have different values) end duplicate component/@id attributes. important because having same registry key in 2 different components breaks component rules.

one last little thing. careful using -gg switch heat. every time run tool generate new guids components. not allowed once components ship because again violation of component rules. recommend using -ag switch instead let auto-guid mechanism take care of managing guids correctly.

php - Why I am getting the Error "Commands out of sync; you can't run this command now" -

the documentation of error mentioned in title says if commands out of sync; can't run command now in client code, calling client functions in wrong order. this can happen, example, if using mysql_use_result() , try execute new query before have called mysql_free_result(). can happen if try execute 2 queries return data without calling mysql_use_result() or mysql_store_result() in between. from here: http://dev.mysql.com/doc/refman/5.0/en/commands-out-of-sync.html but in first query not fetching data mysql database, inserting. , in second query getting data database. here code $connection = mysqli_connect("localhost","username","password","tbl_msgs"); if(mysqli_connect_errno($connection)) { die("failed connect mysql: " . mysqli_connect_error()); } $query = "insert users (total_comments, total_views) values ({$total_comments}, {$total_views});"; $query .= "insert msgs (no...

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...
