c# - Unreachable Code Detected Return Value -


how return value issue? me please. 

protected string sendstate(object id_dip,object id_seq,object modul) {     try     {         viewstate["ssdip"] = id_dip.tostring();         viewstate["ssseq"] = id_seq.tostring();         viewstate["ssmod"] = modul.tostring();          return id_dip.asstring();         return id_seq.asstring();         return modul.tostring();     }     catch (exception)     {         return "";     } }

first thing u have multiple return values, ur code wouldn't work, u can use list<string> & return in catch case, u use var @ top of method definition, this--->

public list<string> sendstate(object id_dip,object id_seq,object modul) {      var returnvalue = new list<string>();           try           {                 viewstate["ssdip"] = id_dip.tostring();                 viewstate["ssseq"] = id_seq.tostring();                 viewstate["ssmod"] = modul.tostring();                   returnvalue.add(id_dip.asstring());                 returnvalue.add(id_dip.asstring());                 returnvalue.add(modul.tostring());            }           catch (exception)           {                 returnvalue = null;           }      return returnvalue; }

now u can use above method this--->

var result = sendstate( params )  //<--- params r ur parameters if(result != null)     // proceed else     // no value found

css - Text drops down with smaller window -

i've adapted css use in website , can't quite figure out why 1 aspect of page acting way acting. basically, when shrink window below size horizontally, of text "drops down". becomes issue if user viewing website through ipad vertical orientation. can view issue here . i'm hoping make if window gets smaller, placement of text remains intact. the problem area not have enough space put both side navigation , content on 1 line. make automatically adjust page's width when exceeds decrements of width. this code example, , highly unlikely work. if see css more clearly, provide exact code. @media , (max-width:960px) { /* assuming #wrapper 960px across */ #content {width:560px;} /* opposed 720px */ } edit the content drops down @ 980px, have shrink width after there. @media , (max-width:980px) { #container {width:520px;} }
