scala - Why is starting a Blaze server that supports websockets different than a server that does not support it in Http4s -

-

here sample code start blaze server supports websockets in http4s:

https://github.com/http4s/http4s/blob/master/examples/blaze/src/main/scala/com/example/http4s/blaze/blazewebsocketexample.scala#l53

it quite different in case websocket support not required:

https://github.com/http4s/http4s/blob/master/examples/blaze/src/main/scala/com/example/http4s/blaze/blazeexample.scala#l8

why case? possible add withwebsocketsupport on blazebuilder?

i mean, if api can improved, that's great, trying understand how websocket support fits picture because having issues getting web server (that supports websockets) function properly.

i using exp calculate total fees paid on rdlc report: =sum(iif(fields!responsedescription.value ="approved successful",int(fields!amount.value), 0)) and #error in resulting column , can issue ? . and similar exp above work fine : =sum(iif(fields!responsedescription.value <> "",int(fields!amount.value), 0)) few notes: 1- amount integer , present. 2- responsedescription string , present. thank you you can use expression: =sum(cint(iif(fields!responsedescription.value ="approved successful", fields!amount.value, 0))) you have convert every possible values same type before aggregation. i think second expression works fine because in true case ( fields!responsedescription.value <> "" ) used expression converted integer .
