when deriving gobject class in pygtk, can define gobject properties in c, using __gproperties__ dict, , do_get_property / do_set_property methods, described here in sub-classing gobject in python . note written before had @property decorator in python. gobject properties have advantage can connect object's notify::property-name signal receive notification whenever property changes. other that, there reason use gobject properties instead of python's @property decorator? why not use them? simplified version provided python bindings, defining gobject properties not different defining python properties. having said that, there couple of advantages other notification. 1 i've made use of in past property setting in gtk.builder files. example, in ui file, <object class="gtkimage" id="image"> <property name="stock">gtk-missing-image</property> </object> sets stock property on image object when const...

when binding this: <div data-bind='template: { name: "persontemplate", foreach: someobservablearrayofpeople }'> </div> is possible specify sort of separator template, similar separator template in classic asp.net? there not way specify separator template. however, think there few options: include content in "persontemplate" use wrapper template renders persontemplate , separatortemplate , point template binding (that way reuse separator template, if necessary) use afterrender option of template binding insert content.

this line in program: invest(initial_amount,top_company(5,year,year+1)) = subsequent_amount causes me error: syntaxerror: can't assign function call how fix , make use of value of function call? syntactically, line makes no sense: invest(initial_amount,top_company(5,year,year+1)) = subsequent_amount you attempting assign value function call, error says. trying accomplish? if you're trying set subsequent_amount value of function call, switch order: subsequent_amount = invest(initial_amount,top_company(5,year,year+1))

for example, of entities have datecreated , datemodified fields. defaults these set getutcdate() in sql server. if try , create entity , don't set these values, exception saying can't run sql insert because date value out of range. makes sense because c# default dates 1/1/0001 while sql server's minimum date 1/1/1753. so there way can tell ef either use sql server default values, or not try , insert columns have not been set? you must set storegeneratedpattern properties identity datecreated , computed datamodified . available in designer. once cannot modify values in application - database can set properties. wrote some article because feature had bug before vs2010 sp1 there reports still doesn't work sometimes.

when wpf window appear first time, content seem frozen. refresh content need resize form, fixed. or hit tab find listbox -it's not visible- , click , viola! form updates content again. what think? weird huh? in advance! edit: private void window_loaded(object sender, routedeventargs e) { this.show(); while (!appmain.needclose) { system.windows.forms.application.doevents(); dothings(); } } resizing window force internals invalidate , re-paint. try invalidating form when it's loaded force same: private void window_loaded(object sender, routedeventargs e) { this.show(); this.invalidate(); while (!appmain.needclose) { system.windows.forms.application.doevents(); dothings(); } } unless you're doing sort of custom message pumping though, standard forms message pump should while loop you. might find because you're intercepting window loaded event you're stopping initialisation completing. call...

i'm attempting basic parallelisation using _beginthreadex, , passing parameters per example given, won't work. any ideas? #include <iostream> #include <process.h> void mythread(void *data) { std::cout << "hello world!"; } int main() { _beginthreadex(null, 0, mythread, null, 0, null); while(true); } edit: why won't passing null argument work? (since function takes no arguments anyway?) passing null arguments list worked fine _beginthread. your code has 2 errors in it, neither of related parameter thread function --- null fine that, surmised. the problems in signature of thread function, , error getting points out. firstly, must __stdcall function, , secondly must return unsigned int . function __cdecl , returns void . unsigned __stdcall mythread(void *data) { std::cout << "hello world!"; return 0; } should fix problem you.
