Silverlight - WCF get clientaccesspolicy on localhost -

-

i have silverlight application uses wcf communications server. both silverlight , wcf running on local machine (localhost). when silverlight makes call service fails aa communication exception. understand because don't have clientaccesspolicy file, since wcf endpoint running on http://localhost:port defined interface, ipolicyretriver, , added implementation service returning clientaccesspolicy in stream.

my question is, have configure run without problem? understand have change or add servicereference.clientconfig file, don't understand what. i've included servicereference.clientconfig below. please let me know change or add it, , in silverlight add code. please not paste links here me have opened every link during last 2 days - still don't understand.

<configuration> <system.servicemodel>     <bindings>         <basichttpbinding>             <binding name="basichttpbinding_imapservice" maxbuffersize="2147483647"                 maxreceivedmessagesize="2147483647">                 <security mode="none" />             </binding>         </basichttpbinding>     </bindings>     <client>         <endpoint address="../mapservice.svc" binding="basichttpbinding"             bindingconfiguration="basichttpbinding_imapservice" contract="mapservice.imapservice"             name="basichttpbinding_imapservice" />     </client> </system.servicemodel>

help me please!

you haven't included ipolicyretriever implementation mention, here sample can use.

the interface specification:

[servicecontract] public interface ipolicyretriever {     [operationcontract, webget(uritemplate = "/clientaccesspolicy.xml")]     stream getsilverlightpolicy();      //[operationcontract, webget(uritemplate = "/crossdomain.xml")]     //stream getflashpolicy(); }

the implementation of interface:

    // ipolicyretriever implementation     private stream stringtostream(string result)     {         weboperationcontext.current.outgoingresponse.contenttype = "application/xml";         return new memorystream(encoding.utf8.getbytes(result));     }      public stream getsilverlightpolicy()     {         string result = @"<?xml version=""1.0"" encoding=""utf-8""?>           <access-policy>             <cross-domain-access>               <policy>                 <allow-from http-request-headers=""*"">                   <domain uri=""*""/>                 </allow-from>                 <grant-to>                   <resource path=""/"" include-subpaths=""true""/>                 </grant-to>               </policy>             </cross-domain-access>           </access-policy>";          return stringtostream(result);      }

then can include following in server's configuration xml file. needs on server side, not on client side. i'm emphasising because included client config above in question.

<behaviors>   <endpointbehaviors>     <behavior name="webhttpnewbehavior">       <webhttp />     </behavior>   </endpointbehaviors>   ... </behaviors> <services>   <service behaviorconfiguration="newbehavior">     <endpoint behaviorconfiguration="webhttpnewbehavior" binding="webhttpbinding"                 bindingconfiguration="" name="policyendpoint" contract="wcfservice.ipolicyretriever" />     ...   </service> </services>

alternatively if decide create host programmatically (this how it, rather use clientconfig file, above sample might not 100% correct):

servicehost host = new servicehost(servicetype); host.addserviceendpoint(typeof(ipolicyretriever), new webhttpbinding(), "").behaviors.add(new webhttpbehavior());

i know asked not provide links used http://blogs.msdn.com/b/asiatech/archive/2010/05/07/how-to-consume-a-self-hosted-wcf-service-in-a-cross-domain-environment-by-silverlight-client.aspx reference refresh memory, because don't have access silverlight/wcf project right @ minute.

javascript - Enclosure Memory Copies -

-
function myclass() { //lots , lots of vars , code here. this.bar = function() { //do numerous enclosed myclass vars } this.foo = function() { alert('hello'); //don't enclosed variables. } } each instance of myclass gets own copy of bar , foo, why prototyped methods use less memory. however, know more memory use of inner methods. it seems obvious me (1) below must true. agree? not distinct myclass instances have own distinct copies of bar, must have own distinct copies of myclass enclosure. (or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

php - Replacing tags in braces, even nested tags, with regex -

-
example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
