linq - "Cannot Convert Lambda Expression to Delegate type" Error in RavenDB query -

-

i have ravendb document looks this:

{   "parentid": null,   "order": 10,   "url": "/sandbox",   "rows":    [     {       "instanceid": "2771a0d7-7f3f-4854-a3ba-27f25f88a45e",       "cssclass": null,       "columns":        [         {           "instanceid": "b91495f5-b770-4da7-8073-ad3bd8221ca8",           "cssclass": null,           "span": 3,           "cmsmoduleinstancesettings":            [             {               "$type": "modulehtml.models.modulehtmlinstancesettings, modulehtml",               "isactive": false,               "showauthor": false,               "showdate": false,               "showcommentscount": false,               "showlast2comments": false,               "cmsmoduleinstanceid": 417,               "containerclass": "default",               "moduletype": "modulehtml",               "displaytype": "summary"             },             {               "$type": "modulehtml.models.modulehtmlinstancesettings, modulehtml",               "isactive": false,               "showauthor": false,               "showdate": false,               "showcommentscount": false,               "showlast2comments": false,               "cmsmoduleinstanceid": 545,               "containerclass": "default",               "moduletype": "modulehtml",               "displaytype": "summary"             }           ],           "id": 0,           "name": null,           "createdon": "0001-01-01t00:00:00.0000000",           "createdby": 0,           "lastmodifiedon": "0001-01-01t00:00:00.0000000",           "lastmodifiedby": 0         },         ...       ],       ...     },     ...   ],   ... }

and want retrieve page document , include rows, columns , cmsmoduleinstancesettings active.

i have tried:

var page = documentsession.query<cmspage>()              .singleordefault(p => p.id == pageid)              .rows              .any(x => x.columns                .any(z => z.cmsmoduleinstancesettings                  .where(m => m.isactive == true)));

but returns :

error 1 cannot convert lambda expression delegate type 'system.func<cms.models.cmscolumn,bool>' because of  return types in block not implicitly convertible  delegate return type

what doing wrong?

you aware doing query in memory filter, right?

split this:

  var page = documentsession.query<cmspage>()          .singleordefault(p => p.id == pageid);

and:

  var rows =             page.rows          .any(x => x.columns            .any(z => z.cmsmoduleinstancesettings              .where(m => m.isactive == true)));

where error now?

c++ - Using OpenSSL in a multi-threaded application -

-
i have been writing soap client application in c++ on ubuntu using openssl https transport , pthreads threading. have number of threads - 1 central data acquisition thread periodically gets worker threads make soap requests via shared mutex protected queues. reading documentation openssl found is openssl thread-safe? in openssl faq describes mechanisms required ensure thread safety when using openssl. implemented , works fine. the reason question conceptual difficulty really. thinking implementing same functionality application has already, instead of using threads, create 2 seperate applications : 1 worker thread (of multiple copies running) , main data acquisition thread. use tcp sockets communicate between 2 rather mutex protected queues. may bad idea not important - confusing me would have implement same functions required ensure openssl thread safety in second approach or not? my guess not have , treated independent (indeed surely must many applications use openssl) re...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
