i have created in past msi have used deploy application. now, want distribute new update of product mst msi (since have changed msi , want transformation applied). problem transform file applied on new installations, seems not applied on installed places. in order fix this, way have found going hklm\software\classes\installer\<gid> , add mst there in transform key. requires lot of manual work, finding actual productcode add key to, copying mst somewhere permanent, etc. can think on other way done? what's update product? if build major upgrade apply new transform when install new upgrade msi file. you shouldn't expect hack system enough think there's transform present isn't! far easier change 1 file in product , create patch include changes in transform 1 new file. patch isn't new file - it's changes between 2 msi files, , doing safer , more reliable.

java - Undesrstanding clone method for arrays -

i've learnt arrays clone method well-behaved , can use it. thought type of elemetns arrays hold should have implemented cloneable interface. let me provide example: public class test { public static void main(string[] args){ test[] arr_t = new test[1]; arr_t[0] = new test(10); test[] an_arr = arr_t.clone(); an_arr[0]= new test(5); system.out.println(an_arr[0].test); //5 system.out.println(arr_t[0].test); //10 } public static class test{ public int test; public test(int test) { this.test = test; } } } demo i thought 5 should have been printed twice. reason clonning arrays we're creating new arrays containing references objects first array holded (because type of elemnts not implement cloneable ). couldn't straighten things out? it's not clear if it's neccesary array element's type implements cloneable . it's simple concept, seems hard

java - A guaranteed way to get source-order of member fields at runtime? -

-
i'm looking way retrieve (at runtime) fields of class in source-order, can perform own "initialization processing" based on order of declaration. know javadoc class.getdeclaredfields() explicitly states no order guaranteed. some answers on point javassist can find no evidence javassist has such guarantee in absence of line number information. yet "source-order" used java compiler, code not compile: private int = 10 * b; private int b = 5; clearly, value of b isn't known @ moment a being declared. this initialization order must present in bytecode since @ runtime initialization must happen in same order (granted, requirement these edge cases :-( yet leads me think natural thing store source order inside .class file. questions: how jvm/byte code go initializing member fields in declared order, , can information perhaps used reconstruct source-order of fields? is there other guaranteed way of achieving same. third-party tools javassist
