for little background story, work in computer lab , need have easy method disable network protocol bindings on adapters based on pci bus locations. so far have written c# command line utility find them, bus locations, netcfginstanceid, etc. 1 thing haven't figured out how remove bindings on adapters, go through , remove them in registry still show in adapter settings. eventually found out neat utilities in windows ddk, bindview sample program, want take netcfgapi included in bindview sample , use in c# program, problem c++ files. have tried using midl convert them .ddl or .tlb can use pinvoke on know little pinvoke , midl compiler comes errors such "midl : command line error midl1003 : error returned c preprocessor (4)". my question is, there easier way this? , if there not, best way go converting netcfgapi c++ files usable in c#? i write utility in c++ more comfortable using c#. you try compiling stuff c++/cli dll. in project settings under compiler,...

i have active directory federation services 2.0 setup , ready work, have scenario falls outside pretty i've read on enabling relying party application. 2 scenarios documented involve a) passive authentication web site or b) using thick client that's authenticated calling web services. my scenario follows: have web application calls wcf services via net.tcp data access. need use adfs 2.0 secure each wcf call secure token. i can't use use passive method of authenticating adfs web site (security restrictions outside control). so question is, possible manually request secure token adfs via web site, use same token call wfc service methods? have @ http://travisspencer.com/blog/2009/03/caching-tokens-to-avoid-calls.html . in blog post described how cache security tokens wcf service calls. i think should possible "inject" fetched token in described "cachesecuritytokenprovider".

i'm losing here.. extremely confused how loop works. from w3 schools: var person={fname:"john",lname:"doe",age:25}; (x in person) { document.write(person[x] + " "); } person object properties right? how properties being accessed brackets? thought arrays? why work, , shouldn't this?: var person=[]; person["fname"] = "john"; person["lname"] = "doe"; person["age"] = "25"; (x in person) { document.write(person[x] + " "); } there 2 ways in have access object's properties: obj.key obj['key'] the advantage of second method can provide key dynamically, e.g. obj[x] in example. obj.x literally mean x property (i.e. obj['x'] ), not want. arrays work brackets, brackets not limited arrays. arrays under hood objects, designed numeric keys. can still add properties non-numeric keys them, that's not designed for.

example: if use arabic language text field direction rtl , if want write new text , switch english language direction inside text field (`text-align: left) ltr automatically you use global html5 attribute dir value of auto here, so: <input type="text" dir="auto" /> from specification: the auto keyword, maps auto state indicates contents of element explicitly embedded text, direction determined programmatically using contents of element (as described below). note : heuristic used state crude (it looks @ first character strong directionality, in manner analogous paragraph level determination in bidirectional algorithm). authors urged use value last resort when direction of text unknown , no better server-side heuristic can applied. http://www.w3.org/tr/html5/elements.html#the-dir-attribute as quote suggests, better find out on server side direction should used, can use if have no way of knowing it.

i might getting myself confused here want service idempotent. is, receiving same request more once not change state of system. makes sense me when receiving messages in disconnected integration system. example, receiving messages on msmq , having form of service dealing messages being received. want service in consistent state if receives 10 duplicate messages. what struggling head around standard wcf soap service performs crud operations. idempotency question come affect if asynchronous call? syncrhonous call nature idempotent? looking @ crud operations, 1 not idempotent create. can have duplicate create calls wcf? thanks i guess depend on define (in domain) duplicate. once defined can run checks before creating record. e.g. have person firstname , lastname , etc... duplicate person identified firstname + lastname . what kind of duplicate messages expect service receive? same client 'clicking submit button twice'? or 2 different clients trying update record...

i have stream writer opens using webclient.openwrite call. simplified case, assume reader reading multiple of datachunksize. using (stream writer = mywebclient.openwrite(myuristring) { using (filestream reader = new filestream(myfilename, filemode.open, fileaccess.read) { for(int = 0; < reader.length; += datachunksize) { byte[] data = new byte[datachunksize]; reader.read(data, 0, datachunksize); writer.write(data, 0, datachunksize); } reader.close(); reader.dispose(); } writer.close(); writer.dispose(); } my data size of 2 datachunksizes. however, not send data (no data received) until writer.close() call called, sends first datachunksize worth of data...the second datachunksize of data never sent. how can send after every write call? tried adding writer.flush() did not help. thanks. i think issue because last chunk perhaps not full length expect (datachunksize)....

i've been doing prototype work on new silverlight application using caliburn micro our mvvm framework. team has been happy it. in order address issues throttling requests services, suggested reactiveui's reactivecollections , implementation of inotifypropertychanged. does have experience around using 2 together? since both mvvm frameworks, there's bit of overlap, wonder if might more trouble it's worth try , make them work together. some of things caliburn micro are: the convention based binding, etc...very nicely done in our opinion. bootstrapping. way handled, it's easy extend when need to, out of box stuff works many of our use cases. composition/screen management. rob's notion of conductors, screens, etc. flows nicely us. the reactiveui stuff has drawn (at least initially). the reactive collections , inotifypropertychanged stuff. particularly ability throttle reactions. reactive's asynchronous stuff seems bit cleaner deal rob's c...

can in writing custom content provider multiple tables. can write single table multiple table did not find example. a near duplicate of existing answer. compare this question , answer , discussing use of left join inside contentprovider. note that, in all, expected use of contentproviders use single tables each path in content uri. it's still seen out of norm use join or index multiple tables in 1 call. not it's bad, there aren't many people thinking in terms.
