i trying figure out why typescript not picking "default export" of react . e.g. in javscript files using: import react 'react'; import reactdom 'react-dom'; but in typescript have use (after googling): import * react "react" import * reactdom "react-dom" i starting out fresh project after being unable import existing project , g et vs2k15 compile it. what difference, if any? there way specify "module 'react' has no default export" . i can see in react file there declare module "react" { export = __react; } is not considered default export i tried import __react "react" but same error. a default export giving 1 of exports alias "default". can using following syntax: export default function __react { //do work } you can use following syntax: function __react { //do work } export {__react default};

i using libraries build cards, java extends library class have requirement use fragmentmanager in java class tried using inner class getting null pointer exception if have activity reference: activity.getfragmentmanager() if have fragment reference: fragment.getfragmentmanager() they both public methods, you'll need reference either activity or fragment. also, , though don't recommend it, if have view reference, view.getcontext() method likely activity , might able cast , fragmentmanager way. potentially dangerous, , stop working @ moment if android's implementations change, should know you're doing. passing activity/fragment reference way go.

i trying implement spatial domain fingerprint quality analysis. quality measure shown in below: i able implement till equation 9. next step calculate weight shown in equation 11. when tried implementing weights zero. of great if me fix issue. have attached code below: clc;clear all;close all; img = imread('c:\users\shrey\google drive\quality\testdatabase\fvc2004\db1_b\101_2.tif'); b = 2; br=1; img=finger_segment(img); img(img==0.5)=0; [gx,gy]=gradient(img); = 1 :b: size(img,1) j = 1 :b: size(img,2) % gradients blockwise gx1 = gx(i:min(i+b-1,size(gx,1)),j:min(j+b-1,size(gx,2))); gy1 = gy(i:min(i+b-1,size(gy,1)),j:min(j+b-1,size(gy,2))); temp = img(i:min(i+b-1,size(img,1)),j:min(j+b-1,size(img,2))); if (any(any(temp)) == 1) k(br) = coherence_grad_3(gx1,gy1,b); temp2=temp/sum(temp(:)); % centroid calculation [r1,c1]=size(temp); [i,j]=ndgrid(1:r1,1:c1); li(br,:)=[dot(i(:),te...
