i'm using url.action generate link in e-mails (with postal mvc framework) sent application, however, links generates showing "localhost" name, , not domain name. i'm using following code: @url.action("alterarsenha", "account", null, this.request.url.scheme) the result following: http://localhost/account/alterarsenha after that, tried following code: @url.action("alterarsenha", "account", null, this.request.url.scheme, request.servervariables["http_host"]) and got same result. how can link domain like: http://www.servicili.com/account/alterarsenha assuming want use domain name in url when application runs on localhost, use overload of url.action : public virtual string action( string actionname, string controllername, routevaluedictionary routevalues, string protocol, string hostname ) and pass domain name hostname . https://msdn.microsoft.com/en-us/library/system

i have formula working, looks value , if there match between sheets prints out row match in. if match if found copy value column b in same row value found. so if match found between a2 in sheet1 , range a:a in sheet2, , lets row 5, want copy b5. possible? =if(iserror(match(a1;indata!a:a;0));""; match(a1;sheet2!a:a;0)) =if(iserror(match(a1,sheet2!a:a,0)),"",index(sheet2!b:b,match(a1,sheet2!a:a,0)))

i use inkscape generate custom google markers application i'm creating. since google maps don't support svg files directly, i'm planning change parameters inside svg file then, redirect file inkscape , print exported png standard output, cgi script can use sending results browser display. do have suggestions on how achieve that? in unix/linux environment, can use pseudofiles /dev/stdin , /dev/stderr achieve this, e.g. bash shell: cat file.svg | awk -f script.awk | inkscape /dev/stdin -e /dev/stderr 2> file.png note inkscape sends text output /dev/stdout (which weird choice), hence have use stderr not image mixed text.

i'm calling matlab program eclipse java interface. have used matlabcontrol it. when run java program multiple time, every time opens new instance of matlab, , makes computation slower. is possible can prevent opening new instances of matlab? if possible, how can this? if have opened terminal of matlab, possible computation can use terminal, instead of opening new instance of matlab? any appreciable. the matlabcontrol can not connect open instance of matlab, can create new one. to prevent multiple matlab instances being opened, can use proxy.exit() instead of proxy.disconnect() close matlab when closing application. to further use single instance of matlab across multiple instances of java program, see different possibilities no one. matlab comes it's own jvm , start java applications matlab console using . officially documented, can call java functions matlab, other way round possible well . please matlab uses it's own jvm might outdated. implem

my web app works great in chrome handles configuration changes (such screen rotation) excellent. preserved. when loading web app webview in android app web app loses state on screen orientation change. partially preserve state, i.e. preserves data of <input> form elements, javascript variables , dom manipulation gets lost. i webview behave way chrome does, i.e. preserving state including javascript variables. should noted while chrome , webview derives same code base chrome not internally use webview. what happens on screen orientation change activity (and eventual fragments) gets destroyed subsequently recreated. webview inherits view , overrides methods onsaveinstancestate , onrestoreinstancestate handling configuration changes hence automatically saves , restores contents of html form elements back/forward navigation history state. state of javascript variables , dom not saved , restored. proposed solutions there have been few proposed solutions. of them

i have pandas dataframe contains 2 date columns, start date , end date defines range. i'd able collect total count dates across rows in dataframe, defined these columns. for example, table looks like: index start_date end date 0 '2015-01-01' '2015-01-17' 1 '2015-01-03' '2015-01-12' and result per date aggregate, like: date count '2015-01-01' 1 '2015-01-02' 1 '2015-01-03' 2 and on. my current approach works extremely slow on big dataframe i'm looping across rows, calculating range , looping through this. i'm hoping find better approach. currently i'm doing : date = pd.date_range (min (df.start_date), max (df.end_date)) df2 = pd.dataframe (index =date) df2 ['count'] = 0 index, row in df.iterrows (): dates = pd.date_range (row ['start_date'], row ['end_date']) date in dates: df2.loc[

my swift program crashing exc_bad_instruction , error. mean, , how fix it? fatal error: unexpectedly found nil while unwrapping optional value this post intended collect answers "unexpectedly found nil" issues, not scattered , hard find. feel free add own answer or edit existing wiki answer. this answer community wiki . if feel made better, feel free edit it ! background: what’s optional? in swift, optional generic type can contain value (of kind), or no value @ all. in many other programming languages, particular "sentinel" value used indicate lack of value . in objective-c, example, nil (the null pointer ) indicates lack of object. gets more tricky when working primitive types — should -1 used indicate absence of integer, or perhaps int_min , or other integer? if particular value chosen mean "no integer", means can no longer treated valid value. swift type-safe language, means language helps clear types of values cod
