dynamics crm - RetrieveMultipleRequest.MinActiveRowVersion what it this and when is it ever not -1 -


i have been investigating ways synchronise incremental changes dynamics crm.

i stumbled accross minactiverowversion property of retrievemultiplerequest

        var orgservice = serviceprovider.getorganisationservice();         using (orgservice idisposable)         {              var accounts = orgservice.retrievemultiple(new queryexpression("account") { columnset = new columnset("accountid") });             console.writeline("min active is: " + accounts.minactiverowversion);          }

this property returns "-1" during testing, when trying simulate transactions going on in background, tricky do.

my understanding of minactiverowversion sql perspective comes here:-

[http://technet.microsoft.com/en-us/library/bb839514.aspx][1]

so question is, able clarify minactiverowversion property is, because can't find useful in sdk documentation!

to best of knowledge , experience never used , equal-1. under cover hard coded long , converted string when entitycollection object built - -1.

the sdk defines as "the lowest active row version value" implies related sql row versions, crm not make use of field. defined same in crm 2011 , crm 2013 sdks.

in crm 4 had businessentitycollection, entitycollection's predecessor. had unused string property called version.

my guess, when crm 2011 being designed got added potential functionality - didn't survive - , never removed before went rtm. once released product team didn't want change class definition , break existing code left there live on returning -1.

opencv - DataType<cv::detail::deriv_type>::depth what is it used for -

i wondering why line used in lucas kanade tracker in opencv: datatype<cv::detail::deriv_type>::depth can explain me? in opencv, depth of mat refers type of data contained in mat 's data buffer. represented integer values correspond given data type. these integers commonly abstracted appropriate macro definition (e.g. uchar data represented macro cv_8u ). cv::datatype type-traits class provides method obtain corresponding integer value without having memorize macro means data type. there few cases user code needs use datatype::depth . more common datatype::type . a simple example shows 1 possible use of datatype::depth : cv::mat uchar_data = cv::mat::ones(3, 3, cv_8uc1); cv::mat float_data; uchar_data.convertto(float_data, cv::datatype<float>::depth); // ^^ equivalently replaced // cv_32f macro float_data.at<float>(0,1) += 0.5f; std::cout << float_data << std::endl;...

python 3.x - Mapping specific letters onto a list of words -

can please suggest approach write piece of codes automatically maps letter in letter_str onto dic_key (a dict key string type contains dashes match length of words in word_lst)? so, mapping occurs if letter appears in every words in list @ same position no matter how many words in list. if no letter appears @ position words in word list new_dic_key '----'. please see examples below thanks word_lst = ['ague', 'bute', 'byre', 'came', 'case', 'doze'] dic_key = '----' letters_str ='abcdefghijklmnopqrstuvwxyz' new_dic_key = '---e' if word_list = ['bute', 'byre'] new_dic_key = 'b--e' or word_list = ['drek', 'drew', 'dyes'] new_dic_key = 'd-e-' if words in word_list of same length code give want: word_list = ['drek', 'drew', 'dyes'] cols = [] in range(len(word_list[0])): cols.append([]) word in ...
