is ok use html below style anchor block element? read somewhere before it's wrong, can't see why , it's damn convenient! drawbacks of method, if any? <style> a.button{ display:inline-block; padding: 10px 20px; border: 1px solid grey; } </style> <a class="button" href="#link">click me!</a> not ok <a> elements styled blocks or inline-blocks, it's necessary in cases, avoid problems. take bit of code: a {outline:1px dotted} click <a href="#"><div>here</div></a> in browsers, outline around anchor not proper rectangular shape, because of div inside. in others, outline isn't there @ all. if change a's display block , differences go away; has nice rectangular outline in browsers. a {outline:1px dotted; display:block} click <a href="#"><div>here</div></a> so, no need worry.

i trying change data table multiple criteria sub-query this: update field0 f0 set f0.c=iif(table.field="x","a",iff(table.field="y","b","c")) ( select f2.b field (field1 f1 inner join field2 f2 on f1.a=f2.a) inner join field0 f00 f00.a=f1.a ) table ; but it's not working, says have problem how wrote query. i tried this: update field0 f0 set f0.c=iif(f0.a=any( select f1.c field1 f1 inner join field2 f2 on f1.a=f2.a f2.b=4),"a",iif(f0.a=any( select f1.c field1 f1 inner join field2 f2 on f1.a=f2.a f2.b not null),"b","c")) ; but 1 says query not updatable query :/ i dont know do, help? this actual code wroth: update flights f set f.status = (select iif(de.handeling_code=4,"canceled",iif(de.handeling_code not null,"on time ","late")) irregular_events ie inner join delay_event de on ie.ie_code=de.delay_code ie.flight_code=f.flight_code order f.fl

i'm trying model impact of storms on sales patterns using causalimpact package. when create zoo object , pass model receive error. i've read through documentation , can't figure out i'm doing differently examples in documentation. i'm working following data.frame: > head(my.data) date sales units 1 2014-10-17 71319.85 21436.64 2 2014-10-18 88598.26 26755.79 3 2014-10-19 95768.29 29823.86 4 2014-10-20 62303.04 19417.71 5 2014-10-21 56477.57 17562.21 6 2014-10-22 54890.39 16946.43 then i'm converting zoo object: my.data<- zoo( my.data[ ,c('sales','units')], my.data[,'date'] ) > str(my.data) ‘zoo’ series 2014-10-17 2017-04-13 data: num [1:907, 1:2] 71320 88598 95768 62303 56478 ... - attr(*, "dimnames")=list of 2 ..$ : null ..$ : chr [1:2] "sales" "units" index: date[1:907], format: "2014-10-17" "2014-10-18" "2014-10-19" ... then set p

i've been working @ implementing simple serial forking described in tm module's documentation (the q values stored priority weight in mysql table) proxy querying database determine domain forward to. i've verified through extensive use of xlog variable i'm using build new uri use seturi getting correctly. use append_branch call in subsequent while loop iterating on sql query results, doesn't have problems taking formatted parameter. however, when go restart kamailio gripes @ me string expected. line corresponds console seturi call. i've tried casting string, doesn't seem part of 4.4 (or syntax wrong). i've thought building uri strings , storing avp, suspect i'd have same problem. for reference, i'm doing: $var(basedest) = "sip:" + $var(number) + "@" + $(dbr(destination=>[0,0]))+ ":" + $var(port); seturi($var(basedest)); and it's outputting when trying load config: <core> [cfg.y:3368]: yye

so, want lottery results (from site called magayo.com offers free api mega millions) app, "numgen" in windows 10 app store, and, don't know how use apis, of internet tutorials useless , tell me things don't want or need know. want information api , display neatly on app, please me. thank you! you need call api using http request , consume response display results on app. http request can made via xmlhttprequest [xhr], or library jquery ( ajax ) or axios . you can read more on mozilla developer network . also why use javascript develop native apps suitable windows 10? using electron too? developing in c++ improve performance although uwp app supports javascript codebase language too.

i have sql server database. 1 of tables has sql datetime column. column should not have entered when record created, later should modified. i understand datetime not nullable. default datetime2 1/1/0001, while minimum value sql server 1/1/1753. why when insert datetime null have "0001-01-01" in sql server? so, question correct way this? how set po.podate minimum sql server (1/1/1753). applicationdbcontext db = new applicationdbcontext(); purchaseorder po = new purchaseorder(); po.podate = new datetime(1753, 1, 1); // best way? // po.podate = datetime.minvalue; doesn't work because datetime.minvalue 1/1/0001 // po.podate = null; doesn't work because datetime non-nullable value type // po.podate = dbnull.value; doesn't work because type system.dbnull not datetime db.purchaseorders.add(po); db.savechanges(); if expect date not nullable, yes, have best way. ef pass in value field regardless, if don't, try pass i

when serialize page object, json.net not adding $type property controls (which in ilist ) when serializes them. have tried adding following code class constructor , webapi startup, json.net still not adding $type information control serializes. jsonconvert.defaultsettings = () => new jsonserializersettings { typenamehandling = typenamehandling.all, metadatapropertyhandling = metadatapropertyhandling.readahead }; for testing purposes, added $type property control myself in json code, , json.net able deserialize object correctly, still not serializing correctly. here's how classes setup. public class page { public guid id { get; set; } public guid customerid { get; set; } public ilist<control> controls { get; set; } } and here control class: public class control : controlbase { public override enums.cscontroltype cscontroltype { { return enums.cscontroltype.base; } } } and here controlbase ab
