calling a c# wcf webservice from c# client -

-

i have c# wcf web service , c# client makes calls web service working fine , have scenario below unable figure out how it.

here case, have 2 methods in c# client 1st method make more time , client doesn't know going on response wcf web service take long time, implemented 2nd method gives status of 1st method call(saying first method has total of 10 tasks , performing 1 or 2 or 3 etc). don't have idea how call goes 2nd method first method not yet completed , both methods have in same client. can 1 please this.

if have understand correctly... need implement asynchronous invocation. default in wcf calls synchronous.

what have synchronous invocation.:

  1. method1 (client) invokes method2 (server) have tasks done.
  2. method1 waits long time until method2 finishes
  3. method1 receives true (or whatever) method 2
  4. method 1can continue doing things.

what need is:

  1. method1 (client) calls method2 (server)

  2. method2

    2.1 validate request correctly formed

    2.2 creates thread working process

    2.3 returns true (that means ok, have queued request)

    2.4 method1 continue doing stuff.

then have 2 options:

3a. when method2 finishes calls method in client report has finished (say method 3 in client)

3b. method1 query method in server (say method4 in server) see progress of task every x seconds , show on screen or whatever wants until finished.

you can check msdn link how implement asynchronous methods in wcf.

c# - Copy ObservableCollection to another ObservableCollection -

how copy observablecollection item observablecollection without reference of first collection? here observablecollection item value changes affecting both collections. code private observablecollection<ratemodel> _allmetalrate = new observablecollection<ratemodel>(); private observablecollection<ratemodel> _metalrateondate = new observablecollection<ratemodel>(); public observablecollection<ratemodel> allmetalrate { { return this._allmetalrate; } set { this._allmetalrate = value; notifypropertychanged("metalrate"); } } public observablecollection<ratemodel> metalrateondate { { return this._metalrateondate; } set { this._metalrateondate = value; notifypropertychanged("metalrateondate"); } } foreach (var item in metalrateondate) allmetalrate.add(item); what causing , how can solve it? you need clone object referenced item before it's a...

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...
