web services - WCF - HTTP could not register URL http://+:80/ -

-

my first post on stackoverflow!

i having problems wcf service trying build , need in trying figure out.

there 2 parts service, first simple rest style web service full of methods, works fine.

the next area pub/sub model push out subscribers internally results of particular invoke method first area. incorporate listening on 2 endpoints, every time invoke 1 method on pubsub service error above. after searching interwebulator have seen lot of posts saying iis using port 80 default.

now 2 questions: 1. service listening on following base address, nothing 80 http://localhost:3526/tradeportal , http://localhost:3526/tradeportal/operations 2. ideally host in iis

the suggestion change client base address not use port 80, set on sever side or client side config.

i'm bit puzzled solution this, have built pubsub model using nettcp binding.

any clues how solve appreciated

server side config:

<system.servicemodel>     <services>         <service behaviorconfiguration="default" name="cfp_web_lib.tradeportal">           <host>             <baseaddresses>               <add baseaddress="http://localhost:3526/tradeportal"/>             </baseaddresses>           </host>             <endpoint address="" binding="webhttpbinding"                  contract="cfp_web_lib.itradeportal"                       behaviorconfiguration="web"                  />           <endpoint address="operations/" binding="wsdualhttpbinding"                contract="cfp_web_lib.itradeoperations"/>                </service>     </services> <behaviors>   <servicebehaviors>     <behavior name="default">       <servicemetadata httpgetenabled="true"/>       <servicedebug includeexceptiondetailinfaults="true"/>      </behavior>   </servicebehaviors>   <endpointbehaviors>     <behavior name="web">       <webhttp/>     </behavior>     </endpointbehaviors> </behaviors> </system.servicemodel>

client side code (auto generated vs2010)

<system.servicemodel>     <bindings>         <wsdualhttpbinding>             <binding name="wsdualhttpbinding_itradeoperations" closetimeout="00:01:00"                 opentimeout="00:01:00" receivetimeout="00:10:00" sendtimeout="00:01:00"                 bypassproxyonlocal="false" transactionflow="false" hostnamecomparisonmode="strongwildcard"                 maxbufferpoolsize="524288" maxreceivedmessagesize="65536"                 messageencoding="text" textencoding="utf-8" usedefaultwebproxy="true">                 <readerquotas maxdepth="32" maxstringcontentlength="8192" maxarraylength="16384"                     maxbytesperread="4096" maxnametablecharcount="16384" />                 <reliablesession ordered="true" inactivitytimeout="00:10:00" />                 <security mode="message">                     <message clientcredentialtype="windows" negotiateservicecredential="true" />                 </security>             </binding>         </wsdualhttpbinding>     </bindings>     <client>         <endpoint address="http://localhost:3526/tradeportal/operations/"             binding="wsdualhttpbinding" bindingconfiguration="wsdualhttpbinding_itradeoperations"             contract="cfp_web.itradeoperations" name="wsdualhttpbinding_itradeoperations">             <identity>                 <userprincipalname value="callison@cfpartners.local" />             </identity>         </endpoint>     </client> </system.servicemodel>

the problem client not server. wsdualhttpbinding uses 2 connections - 1 client server , 1 server client (to support callbacks). reason why called dual. allow incomming connection client exposes own server (callback implementation) under hood. service must have address , unused port. if not specify address default use port 80 in use iis. must change address on client side. use clientbaseaddress attribute of binding configuration.

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.

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...
