wix - Test for Windows Features -

-

i have installer runs customaction runs embedded powershell script test installed status of various required windows features. works correctly terribly slow complete.

is there alternative method test such features? expect there along lines of registry keys each feature , sub-feature have not found documentation on subject.

in 1 of installation projects used dism.exe enable required windows features.

for example, enabling asp.net in iis 8 done following custom action:

<!-- 32-bit edition of windows knows find dism.exe --> <property id="dismexepath" value="dism.exe" />  <!-- 64-bit edition of windows requires workaround proper dism.exe version --> <setproperty id="dismexepath" value="[windowsfolder]sysnative\dism.exe" after="appsearch">versionnt64</setproperty>  <!-- , ca job (with of [quiet execution ca][2]) --> <customaction id="setforenableaspnetiis8" property="enableaspnetiis8" value="&quot;[dismexepath]&quot; /norestart /quiet /online /enable-feature /featurename:iis-applicationdevelopment /featurename:iis-aspnet45 /featurename:iis-netfxextensibility45 /featurename:netfx4extended-aspnet45 /featurename:iis-isapiextensions /featurename:iis-isapifilter" /> <customaction id="enableaspnetiis8" binarykey="wixca" dllentry="caquietexec" execute="deferred" return="check"/>

this doesn't seem practice, worked project.

java - Copying object fields -

-
what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
