i creating networkimageview programmatically this: final networkimageview niv = new networkimageview(context); niv.setlayoutparams(new viewgroup.layoutparams(viewgroup.layoutparams.match_parent, viewgroup.layoutparams.match_parent)); niv.setscaletype(imageview.scaletype.center_crop); niv.setimageurl("www.example.com/images/example.jpg", imageloader); but scaletype.center_crop feature not working. have idea? thank you. you using scaletype imageview, should using networkimageview niv.setscaletype(networkimageview.scaletype.center_crop); i set image url before scale image.

i access class methods inside class self. know use self keyword in class instance so: class instanceclass { var testproperty = "testing" func testmathod() { print(self.testproperty) } } // initiate let newinstance = instanceclass() newinstance.testmathod() // result testing what's keyword accessing class in static property in below example: class baseclass { static let testproperty = "test" class func printproperty () { // here want access testproperty } } i aware baseclass.testproperty in above example want keep abstract. i have swift 2.11 running. my bad.. self keyword works class methods also. example: class baseclass { class var testproperty: string { return "original word" } static func printtestpropery() { print(self.testproperty) } } class childclass: baseclass { override class var testproperty: string { return "modified word" } } c...

i'm writing application needs perform can be. i'm using vs2012 ide (and compiler). i've noticed, i'm iterating on vectors, pointer solution in contrast iterator, quicker in terms of speed. why that? mean, iterator basicly same thing. should @ least. take @ example: std::vector<int> v; (std::vector<int>::iterator = v.begin(); != v.end(); it++) { // stuff *it } (int* = &v[0], <= &v[v.size()-1]; i++) { // stuff *i } is there optimization needed compiler? i'm using standard settings, -o2 enabled. in advance. edit: i'm compiling in release, , running ctrl+f5 (without debugging is). edit2: actual source-code implementation of quicksort. here link full source , short check out. i'm writing application needs perform can be. then grab profiler , real bottlenecks are. in optimized code (release mode), of course. -o2 not in vs2012: there several #defines manipulate behavior of standard container iterat...

i running tests better understand java generic methods, , came across following problem. have following simple class: 1 public class someclass<o extends object> { 2 3 o somevar; 4 5 public someclass() { 6 somefunc(new number(1)); 7 } 8 9 public void somefunc(o arg) { 10 // code 11 } 12 } as stands, compiler not line 6. eclipse suggests either cast number instance o, or change argument type number on line 9. i avoid both if possible. know modifying class takes care of problem: 1 public class someclass { 2 3 o somevar; 4 5 public someclass() { 6 somefunc(new number(1)); 7 } 8 9 public <o extends object> void somefunc(o arg) { 10 // code 11 } 12 } but brings new problem line 3. so can done original code? thank time!!! the problem in first example creating class someclass o can extends object (or object). ...

i wanna use regular expression find phrases contains 1 - 1 of n words (any) 2 - n words (all ) >>> import re >>> reg = re.compile(r'.country.|.place') >>> phrases = ["this place", "france european country, , wonderful place visit", "paris place, s capital of country.side"] >>> phrase in phrases: ... found = re.findall(reg,phrase) ... print found ... result: [' place'] [' country,', ' place'] [' place', ' country.'] it seems messing around, need specify need find word, not part of word in both cases. can pointing issue ? because trying match entire words, use \b match word boundaries: reg = re.compile(r'\bcountry\b|\bplace\b')

i installed qgis via osgeo4 installation. verified vector , raster data providers working (i have own application use qgis lib display maps). however, when tried launch qgis itself, works except complains no qgis data provider plugins found in c:\osgeo4w64\plugins. don't know gets path necessary libs seem in apps\qgis\plugins folder. i've tried set qgis_pluginpath etc no avail. so, question how "redirect" qgis @ right place gis plugins. i tried run qgis-bin.exe, instead should run qgis.bat launching qgis

i have .net code dealing custom stream need port winrt. motivation is, app reads file encrypted (the custom stream ). in full .net use var readfilestream = file.openread(bookpath); var readdecryptedstream = new mystream(password, readfilestream); //it zip file var readzipfile = new zipfile(readdecryptedstream); //extract files zip file mystream inherits stream , encoding , decoding in read / write methods, full code here http://dl.dropbox.com/u/73642/mystream.cs . code works fine in .net. my winrt implementation is var file =await applicationdata.current.localfolder.getfileasync(bookpath); //i copied same file local folder var filestream = await file.openstreamforreadasync(); var readdecryptedstream = new mystream(password, readfilestream); ziparchive z = new ziparchive(readdecryptedstream , ziparchivemode.read); the problem code new ziparchive(readdecryptedstream , ziparchivemode.read); never finishes reading stream. when set breakpoint in mystream read method,...
