c# - How to avoid MSTDC -


i want synchronize data between 2 sql servers 2008 express edition. avoid escalating sql queries ms dtc service (ms dtc service not running). synchronization use stored procedures without transactions.

i have more stored procedure. procedures download data linked server , store local db works fine.

i using stored procedures upload data linked server. inside stored procedure have no transaction used.

when run stored procedure sql management studio, data correctly uploaded server. when call procedure .net 4.0 c# code, ends error

8501 - msdtc on server 'compname\sqlexpress2008' unavailable.

no transactions used within application code. data uploaded code. cannot figure out when msdtc necessary , when not.

why msdtc needed when no transaction used?

edit1:

i have little progress. code used calling stored procedure. first time when procedure called, data correctly uploaded server. next time ends exception 8501.

  sqlcommand sqlcmd = new sqlcommand("spuploadunsendstockdocument");   sqlcmd.commandtype = commandtype.storedprocedure;   sqlcmd.parameters.addwithvalue("@pdebug", false);   sqlcmd.parameters.addwithvalue("@boxid", boxid);    // return value parameter   sqlparameter returnvalue = new sqlparameter("returnval", sqldbtype.int);   returnvalue.direction = parameterdirection.returnvalue;   sqlcmd.parameters.add(returnvalue);    try   {        using (sqlconnection conn = new sqlconnection(dbconnection.connectionstring))       {         conn.open();         sqlcmd.connection = conn;         sqlcmd.executescalar();         sqlcmd.dispose();         conn.close();       }      if (convert.toint16(returnvalue.value) == 1)       logerror("error while sending");      return convert.toint16(returnvalue.value) == 0;   }   catch (exception ex)   {     log(ex);     return false;   }

why trying manage sync'ing yourself?

how come not using built in replication features built-in sql server 2008 express?

this allow push , pull between databases keep them synchronized.

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 ...
