Reading client side text file using Javascript -

-

i want read file (on client side) , content in array. 1 file. have following , doesn't work. 'query_list' textarea want display content of file. 

<input type="file" id="file" name="file" enctype="multipart/form-data"/>      <script>        document.getelementbyid('file').addeventlistener('change', readfile, false);         function readfile (evt) {            var files = evt.target.files;            var file = files[0];            var fh = fopen(file, 0);           var str = "";           document.getelementbyid('query_list').textcontent = str;           if(fh!=-1) {              length = flength(fh);                      str = fread(fh, length);                   fclose(fh);                               }             document.getelementbyid('query_list').textcontent = str;         }       </script>

how should go it? want loop on array , run sql queries.

if want read files on client using html5's filereader, must use firefox, chrome or ie 10+. if true, following example reads text file on client.

your example attempts use fopen have never heard of (on client)

http://jsfiddle.net/k3j48zmt/

   document.getelementbyid('file').addeventlistener('change', readfile, false);     function readfile (evt) {        var files = evt.target.files;        var file = files[0];                   var reader = new filereader();        reader.onload = function(event) {          console.log(event.target.result);                    }        reader.readastext(file)     }

for ie<10 support need using activex object ado.stream scripting.filesystemobject http://msdn.microsoft.com/en-us/library/2z9ffy99(v=vs.85).aspx you'll run security problem. if run ie allowing activex objects (for website), should work.

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....
