java - not able to parse string into date using jexcel api -

-

i faced problem faced few days ago. have parse file , convert string date. had done same csv file few days ago. however, new file giving error: java.text.parseexception: unparseable date: ""3/4/2011""

why string getting printed 2 "" around it? think root cause of problem. posting code below . please note same code works file date printed 3/4/2011 no "" around it.

     writableworkbook wbwrite=null;      writablesheet sheet=null;      label lwrite=null;      bufferedreader br=null;      number n=null;       string strfile="quotes.csv";  string strline = "";      string st[];      string delimiter="[,]";  int linenumber = 0, tokennumber = 0;     int length=0;     int counter=0;     calendar cal = calendar.getinstance();      datetime datecell=null;       if(strfile.equals("quotes.csv"))      {          system.out.print("in loop if");           try          {             file file=new file("quotes.xls");             wbwrite=workbook.createworkbook(file);             system.out.print("file created");             //path=file.getcanonicalpath();             sheet = wbwrite.createsheet("sheet 1", 0);             lwrite=null;             n=null;             date dtest=null;             dateformat df=null;             date dadd=null;              df=new simpledateformat("dd-mm-yy");      //create bufferedreader read csv file     br = new bufferedreader( new filereader(strfile));     strline = "";     //st[]=empty;             delimiter="[,]";     linenumber = 0; tokennumber = 0;             length=0;     //read comma separated file line line     while( (strline = br.readline()) != null)     {         //system.out.print("strline="+strline);         //break comma separated line using ","         st=strline.split(delimiter);                     length=0;         while(length<st.length)         {             //display csv values             //             system.out.println("line # " + linenumber +                     ", token # " + tokennumber                     + ", token : "+ st[length]);                            if(tokennumber==2)                            {                                  system.out.print("date="+st[length]);                                   dateformat formatter = new simpledateformat("dd-mm-yyyy");                                   date date = (date)formatter.parse(st[length]);                                   system.out.print("date="+date);                                   cal.settime(date);                                   cal.set(calendar.hour_of_day, 17);                                   cal.set(calendar.minute, 30);                                   cal.set(calendar.second, 0);                                   cal.set(calendar.millisecond, 0);                                   date = cal.gettime();                                   system.out.print("date="+date);                                   datecell=new datetime(tokennumber,linenumber,date);                                   sheet.addcell(datecell);                                   lwrite=new label(tokennumber,linenumber,st[length]);                                   sheet.addcell(lwrite);                          }                      if(tokennumber==1||tokennumber==5||tokennumber==6||tokennumber==7)                      {                             n=new number(tokennumber,linenumber,float.parsefloat(st[length]));                            sheet.addcell(n);                      }                      tokennumber++;                      length++;     }     //reset token number             //tokennumber = 0; }     wbwrite.write();     wbwrite.close(); } catch(exception e) {         system.out.print("error="+e); }   }  }

i solved it. string had leading , trailing quotes led double quotes when parsed. that's why ""3/4/2011"". added 

      if (st[length].startswith("\""))      {       st[length] = st[length].substring(1, st[length].length());       }      if (st[length].endswith("\""))   {         st[length] = st[length].substring(0, st[length].length() - 1);   }

plus date format dd-mm-yyyy ; changed dd/mm/yyyy. getting correct answer.

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

razor - Is this a bug in WebMatrix PageData? -

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...

i need sort through array , sort each individual row in array in ascending order. doesn't seem going (surprise!) keep getting hit 2 errors: a2101: cannot add 2 relocatable labels , a2026: constant expected here's sort, makes sense me, think i'm still trying implement high-lvl language techniqes assembly. there way around not being able use relative values? (the array 7 rows 9 columns, btw). mov cx, 7; cx = number of rows outer: ; outer loop walk through rows push cx mov cx, 9 mov row, cx ;rows middle: ; middle-loop walk through columns push cx sub cx, 1 ;cx = cx-1 mov column, cx ;columns inner: ;inner loop - compare , exchange column values cmp marray[row*9 + column], marray[row*9 + column+1] xchg marray[row*9 + column+1], marray[row*9 + column] ; compare , exchange values marray table inc column loop inner pop cx loop mid...
