GWT Frame not working in Mozilla Firefox or in Google chrome, but working fine in IE -

-

i trying download file server. normal gwt rpc call doesnot allow me that, , hence wrote servlet job me. client side, creating frame object, , set servlet url in it, , add frame object in root panel. when execute in ie, window pops asking save/open file. when execute same in firefox or google chrome browser, nothing happing. not getting request on servlet/server side. here slice of code :-

string servleturl = "http://localhost:13080/browser/ui/dataexportservlet?level=zero"; 

          frame frame = new frame(servleturl);     frame.setvisible(false);     rootpanel.get().add(frame);

so, can please me out.

this might related same origin policy. both servlet , webapp running on port 13080? if differ, sop might fail this. if understand correctly, ie has more relaxed policy might work there not in chrome.

see http://en.wikipedia.org/wiki/same_origin_policy , can disable sop (same origin policy) on browser development?

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....
