wpf - How to set the Control Visibilty of the Second Control depending on the Binding Value of the first -

-

i have custom wpf control i.e. combobox:wpftwcombobox. want set visibility using property called disableproviderselector.

the usual use of triggers not helping. scenario here when above control i.e. windowsformshost made visible or collapsed, want opposite happen below custom control. 

<stackpanel grid.row="3" grid.column="2" height="25" orientation="horizontal"                  width="375" horizontalalignment="left">     <windowsformshost height="25" width="375">         <windowsformshost.style>             <style targettype="windowsformshost">                 <style.triggers>                     <datatrigger binding="{binding path=disableproviderselector}" value="true">                         <setter property="visibility" value="collapsed"/>                     </datatrigger>                     <datatrigger binding="{binding path=disableproviderselector}" value="false">                         <setter property="visibility" value="visible"/>                     </datatrigger>                 </style.triggers>                  </style>         </windowsformshost.style>         <commoncontrols:providerselectorcontrol requiredlevel="save" modifiedbyuser="providerselectorcontrol1_modifiedbyuser" x:name="providerselectorcontrol1"/>     </windowsformshost>     <combobox:wpftwcombobox x:name="portalproviderselector"                             selectedvalue="{binding selectedportalprovider}"                             itemssource="{binding path=portalproviderscollection}"                              displaymemberpath="fullname" width="350" height="25"                             requiredlevelflag="save">     </combobox:wpftwcombobox>             </stackpanel>

can please me on how set visibility here?

so disableproviderselector bool when set true windowsformshost needs collapsed , combobox needs visible. reverse when bool false.

so far combobox concerned if bool true it's visible , when false it's collapsed. bind combobox directly property , use booleantovisibilityconverter

xaml:

<window.resources>   <booleantovisibilityconverter x:key="booleantovisibilityconverter" /> </window.resources> ... <combobox:wpftwcombobox x:name="portalproviderselector"                         width="350"                         height="25"                         displaymemberpath="fullname"                         itemssource="{binding path=portalproviderscollection}"                         requiredlevelflag="save"                         visibility="{binding disableproviderselector,                                             converter={staticresource booleantovisibilityconverter}}"                         selectedvalue="{binding selectedportalprovider}" />

c++ - Function signature as a function template parameter -

i'd use function signature template argument. works great classes, when try same trick function templates, msvc throws error: error c2768: 'func' : illegal use of explicit template arguments here's code: template <typename signature> void func(); template <typename r, typename a1> void func<r(a1)>(); what should make work? you cannot partially specialize function template, not supported language. can create partially specialized class template static member function, , possibly trampoline function instantiate class template , invoke static function. something this: namespace detail { template<typename signature> struct helper; template<typename r, typename a1> struct helper<r(a1)> { static void call() { // stuff r , a1... } }; } template<typename signature> void func() { detail::helper<signature>::call(); }

algorithm - What are some ways to combine a number of (potentially incompatible) sorted sub-sets of a total set into a (partial) ordering of the total set? -

-
i have sorting problem i'm pretty sure doesn't have canonical "answer" - has number of different approaches, each pros/cons. i'm interested in hearing different approaches. suppose bunch of people {p_i | i=1,...,m} ranking favorite ice cream flavors. in total there n different flavors, single person p_i ranks n_i << n flavors or familiar with. i'm interested in combining these sub-rankings plausible overall ranking of n flavors. for concrete situation: m , n both 1000 (by coincidence), , each n_i 20 . can assume there's enough overlap in flavors people rank such no flavor "isolated". again, i'm interested in hearing different ways approach this, if there isn't single clear answer. thanks! one way approach problem construct directed cyclic graph representing of constraints on ordering of elements. nodes in graph represent different elements compared , have edge first node second node if had ranked first e...
