facebook c# sdk - Canvas authentication for c# asp.net and general principles -

-

i trying find general principles of using facebook c# sdk write canvas application.

my approach follows. have master page attempt authorise on oninit page. well. first time round not authorized , second time round are. when post goes wrong. have expected authorization / cookies / session item / viewstate item hang around , authorizer item remain authorised.

this appears not case.

should check authorization once , stick auth token in memory? when want information / post information, pass auth token in manually?

is general principle when want post / create new instance of facebookapp , pass in auth token?

here code using.

can general principles specific c#, asp.net, codeplex sdk dlls

many spiggers

public partial class facebook : system.web.ui.masterpage {     protected facebookapp fbapp;     protected canvasauthorizer authorizer;     protected facebooksettings osettings = new facebooksettings();      protected override void oninit(eventargs e) {              //not sure need this, or indeed if works             //httpcontext.current.response.addheader("p3p", "cp=\"idc dsp cor adm devi taii psa psd ivai ivdi coni our ind cnt\"");              osettings.appid = config.facebook.facebookapplicationid;             osettings.appsecret = config.facebook.facebooksecret;             fbapp = new facebookapp(osettings);             authorizer = new canvasauthorizer(fbapp);              if (!authorizer.isauthorized()) // postbacks fail this, reposts , postback event not fire!!!             {                 string scope = "publish_stream,email,user_birthday";                 var url = common.facebook.authorization.authurl(config.facebook.facebookapplicationid, config.facebook.redirecturl, scope);                 var content = canvasurlbuilder.getcanvasredirecthtml(url);                 response.contenttype = "text/html";                 response.write(content);                 response.end();             }             base.oninit(e);         }      }

i want make logharitmic fit. keep getting runtime error: optimal parameters not found: number of calls function has reached maxfev = 1000 i use following script. can tell me go wrong? use spyder still beginner. import math import matplotlib mpl scipy.optimize import curve_fit import numpy np #data f1=[735.0,696.0,690.0,683.0,680.0,678.0,679.0,675.0,671.0,669.0,668.0,664.0,664.0] t1=[1,90000.0,178200.0,421200.0,505800.0,592200.0,768600.0,1036800.0,1371600.0,1630800.0,1715400.0,2345400.0,2409012.0] f1n=np.array(f1) t1n=np.array(t1) plt.plot(t1,f1,'ro',label="original data") # curvefit def func(t,a,b): return a+b*np.log(t) t=np.linspace(0,3600*24*28,13) popt, pcov = curve_fit(func, t, f1n, maxfev=1000) plt.plot(t, func(t, *popt), label="fitted curve") plt.legend(loc='upper left') plt.show() your original data t1 , f1 . therefore curve_fit should given t1 second argument, not t . popt, pcov = curve_fit(func,...

binding - How can you make the color of elements of a WPF DrawingImage dynamic? -

-
we have need make vector graphic images change color of elements within graphic @ runtime. seem setting colors based on either static or dynamic resource values wouldn't work. want have multiple versions of same graphic, each abilty set graphic elements (path, line, etc) different colors don't think dynamic resource approach work. leaves data binding seems right approach. update graphic use data binding expr instead of hard-coded brush color so: <drawingimage x:key="graphic1"> <drawingimage.drawing> <drawinggroup> <drawinggroup.children> <geometrydrawing geometry="f1 m 8.4073,23.9233l"> <geometrydrawing.pen> <pen linejoin="round" brush="{binding line1brush, mode=oneway}"/> </geometrydrawing.pen> </geometrydrawing> <geometrydrawing geometry="f1 m 3.6875,2.56251l"> <geometrydrawing....
