in java , there called package . library in c++ represent same meaning, in terms example of containg relative classes , use of protected members? thanks. there different dimensions of package means in java. container differentiates names of classes inside names of classes in other packages, equivalent c++ namespaces . as unit guarantees access non-private members classes in same block, there no equivalent in c++. access level granted class independent of namespace class defined. as way of ordering sources in disk, there no equivalent, c++ language has no requirements on how code stored in files. regarding c++ libraries, closer jar files in java. bundle different classes share relation. jar can contain more 1 package, , more 1 jar can contain classes same package. libraries, can contain classes different namespaces and/or different libraries can contain classes same namespace.

i want create abstract class common exception handling pattern: public abstract class widget { public ifoo createfoo() { try { createfoounsafe(); } catch(exception ex) { throw new widgetexception(ex, moredata, evenmoar); } } protected abstract ifoo createfoounsafe(); } the intention have standard exception handling pattern across deriving objects. abstract createfoounsafe() method should not expected contain exception handling. implementations single line of return new foo(...) what want know whether there standard naming conventions associated pattern, particularly exception-throwing code expected? the names above seem appropriate, not entirely without smell . the short answer no. there no convention in template pattern designate type , when exception thrown. kind of information included in section of documentation per msdn. using c# , xml comments can generate such documen...

i'm having trouble mappolyline . somehow renders gps trace incorrectly if zoomed out. at low mapcontrol.zoomlevel (eg 9) lines/edges still drawn shouldn't. here screenshots demonstrate odd behavior. http://img403.imageshack.us/g/capture4jz.png/ image description: the first image zoomed out (zoomlevel = 9) (pay attention blue mappolyline) second image zoomed in little (the mappolyline still same same -> incorrect) third image again zoomed in further (however mappolyline looks still similar) last image: actual gps trace looks like. so mappolyline drawing gps trace incorrectly if map zoomed out. seems stops scaling @ point , stays same @ lower zoomlevels (9 - 15 == zooming out) maybe did wrong? can tell me how fix this? workaround? here simple test app demonstrate odd behavior (this behavior same on device , simulator): mainpage.xaml <!--contentpanel - place additional content here--> <grid x:name="contentpanel" grid.row=...
