while building project, got below error message. the type 'tracker_ascx' exists in both 'appdata\local\temp\190\temporary asp.net files\root\web_tracker.ascx.7a9a6bd4.fnv2mhdj.dll' , 'appdata\local\temp\190\temporary asp.net files\root\web_tracker.ascx.7a9a6bd4.pxdl7dxj.dll'. the application runs in .net framework 4.0 this happend because may have reference of old dlls if u added new version. clean solution , rebuild it.

why uses polymorphism in java while using collections. what difference between these initializations. private list<order> orderlist = new arraylist<order>(); private arraylist<order> orderlist = new arraylist<order>(); in second form, orderlist can treated arraylist<order> or inheriting arraylist<order> . in first form, orderlist treated list<order> , recommended when use functionality defined list<t> interface. way code more flexible , can refactored (e.g. realize need linkedlist<t> instead, change initialization , of code not need changed). also, helpful code refactoring use interfaces instead of actual types, if possible (e.g. use parameters of type list<t> instead of arraylist<t> ), because allows caller change list type without changing in called function.

i have 2 codes: normal: int* p[5]; (int i=0;i<5;i++){ int s = rand()%25; p[i]=&s; } dynamic: int* p[5]; (int i=0;i<5;i++){ int* s = new int; *s = rand()%25; //edit: typo, didn't want make random pointer p[i]=s; } now if print array p, p[i] first , then: *p[i] after it, get: static dynamic 0x22ff04 7 0x22ff30 7 0x22ff04 7 0x22ff24 14 0x22ff04 7 0x22ffa6 2 0x22ff04 7 0x22ff89 8 0x22ff04 7 0x22ff13 21 now why elements in p pointing @ same location normal declaration while in dynamic declaration there multiple objects created? why this? in first case, entries point s , left dangling moment s goes out of scope. dereferencing p[i] leads undefined behaviour. in second case, each entry points separate heap-allocated object. here, there's no undefined behaviour (but there's memory leak).
