Visual Studio 2010 Add In using Entity Framework -

-

i'm creating addin launches forms-based gui. addin , gui in different projects. gui connects database , utilizes ef orm.

when launch gui project vs, works great. when publish gui vs add-ins folder , run it, works fine. when launch gui add-in in vs, loads fine, tries hit database fails. ef complains metadata files.

exception: specified named connection either not found in configuration, not intended used entityclient provider, or not valid.

at system.data.entityclient.entityconnection.changeconnectionstring()

here configuration in app.config

  <connectionstrings>     <add name="companyentities" connectionstring="metadata=res://*/;provider=system.data.sqlclient;provider connection string=&quot;data source=testdb;initial catalog=company;persist security info=true;user id=id;password=password;multipleactiveresultsets=true&quot;" providername="system.data.entityclient"/>   </connectionstrings>

the thing can think of "res://*/" portion maps differently when starting assembly different, i've tried using absolute paths csdl/msl/ssdl files without success.

what different launching gui add-in breaks configuration?

don't rely on connectionstring in config file don't control. instead, pass explicitly when new context, using objectcontext overload takes connection string.

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....
