android get url from edit text and use it in rest api to upload data -


here android rest request code url edit text using id "getstring" gets flagged(can't resolved). please 

class restrequest {     //final string add_stroke_url = "";      final string add_stroke_url = new string[]{ getstring(r.id.buttonuploadurl)};      public boolean success = null;     private jsonobject params;     private string strokeid;     private hashset<point> localpoints;     private strokemanagercallback callback;       public static string encode(object x) {         try {             return urlencoder.encode(string.valueof(x),"utf-8");         } catch (unsupportedencodingexception e) {             return(string.valueof(x));         }     }       public restrequest(jsonobject params,string strokeid,set<point> points,strokemanagercallback callback)     {         this.params = params;          this.strokeid = strokeid;          this.localpoints = new hashset<point>();         this.localpoints.addall(points);          this.callback = callback;          new executerest().execute();      }      private class executerest extends asynctask<void, void, string>     {          protected string doinbackground(void ...arg0)         {              /* build url query */             stringbuffer local = new stringbuffer(add_stroke_url);             if(params != null)             {                 local.append("?");                 iterator<?> k = params.keys();                 while(k.hasnext()){                     try {                         string key = (string) k.next();                         object value = params.get(key);                          local.append(encode(key));                         local.append("=");                         local.append(encode(value));                         if(k.hasnext()){                             local.append("&");                         }                     }                     catch (jsonexception e) {e.printstacktrace();}                 }             }              httpurlconnection urlconn = null;             stringbuffer response = new stringbuffer("error");             try             {                 url url = new url(local.tostring());                 urlconn = (httpurlconnection) url.openconnection();                 urlconn.setrequestmethod("get");                 urlconn.setdoinput(true);                 urlconn.setusecaches(false);                 urlconn.setrequestproperty("content-type", "application/json");                 urlconn.connect();                  //get response                 inputstream = urlconn.getinputstream();                 bufferedreader rd = new bufferedreader(newinputstreamreader(is));                 string line;                 response = new stringbuffer();                 try{                     while((line = rd.readline()) != null) {                         response.append(line);                     }                 }                 finally{                     if(urlconn != null){                         urlconn.disconnect();                         urlconn = null;                     }                     if(rd != null){                         rd.close();                         rd = null;                     }                 }                  if(callback != null){                     callback.onsuccess(strokeid, localpoints);                 }             } catch (connectexception e) {                 callback.onfailure(strokeid, localpoints);             } catch (unknownhostexception e) {                 callback.onfailure(strokeid, localpoints);             } catch (malformedurlexception e) {                 e.printstacktrace();             } catch (eofexception e) {                 response = new stringbuffer("no response server");             } catch (ioexception e) {                 e.printstacktrace();             } catch (runtimeexception e) {                 e.printstacktrace();             }             finally{                 if(urlconn != null){                     urlconn.disconnect();                 }             }             return response.tostring();         }     }

you can string resources 

resources res = context.getresources(); final string add_stroke_url = new string[]{ res.getstring(r.id.buttonuploadurl)};

and can pass url in acycnctask class 

public restrequest(jsonobject params,string                     strokeid,set<point>points,strokemanagercallback callback){     this.params = params;    this.strokeid = strokeid;    this.localpoints = new hashset<point>();    this.localpoints.addall(points);    this.callback = callback;     new executerest(/*pass url here in doinbackground method */) .execute();   }  private class executerest extends asynctask<string, void, string>{     protected string doinbackground(string ...arg0){       //get url in arg0 variable       stringbuffer local = new stringbuffer(arg0[0]);             .            .            .       //rest of yours ...

amazon web services - S3 Pre-signed POST validate file type? -

i know it's possible put limit on file size content-length-range header. possible validate file type? https://docs.aws.amazon.com/amazons3/latest/dev/httppostforms.html#policyconditions i see there content-type header, if set say, audio/mp3 allow mp3 files , return error if file not mp3? i found previous question answers mention validating file size: s3 direct upload restricting file size , type you can specify content-type @ post request. you can specify @ signature, post must done content-type: { "expiration": "2007-12-01t12:00:00.000z", "conditions": [ {"acl": "public-read" }, {"bucket": "johnsmith" }, {"content-type: "audio/mp3"} ] } creating html form (using aws signature version 4) edit: @ previous question found, checking content-type.

c# - Check Keyboard Input Winforms -

i wondering if instead of doing this protected override void onkeydown(keyeventargs e) { if (e.keycode == keys.a) console.writeline("the key down."); } i set bool method , this: if(keydown(keys.a)) // whatever here i've been sitting here ages trying figure out how it. can't wrap head around it. in case wondering, plan call bool inside different method, check input. since want perform action after pressing key, using keydown event enough. but in cases suppose want check if specific key down in middle of process, can use getkeystate method way: [dllimport("user32.dll", charset = charset.auto, exactspelling = true)] public static extern short getkeystate(int keycode); public const int key_pressed = 0x8000; public static bool iskeydown(keys key) { return convert.toboolean(getkeystate((int)key) & key_pressed); } you should know, each time check key state using example iskeydown(keys.a) method returns true if ke...
