c# - WCF Self host Publish/Subscribe. How to call publish method from host? -


hello have publish/subscribe wcf service hosted in application rather iis.

here service interfaces

[servicecontract(callbackcontract = typeof(imonitorpublishing))] public interface imonitorsubscribing {     [operationcontract]     void subscribe(int processid);      [operationcontract]     void unscubscribe(int processid);      [operationcontract]     void publishwriteconsole(string name); }   [servicecontract] public interface imonitorpublishing {     [operationcontract(isoneway = true)]     void writeconsole(string line); }

here subcription service

public class monitorsubscriptionservice : imonitorsubscribing {     public delegate void writeconsoleeventhandler(object sender,    serviceeventargs e);     public static event writeconsoleeventhandler writeconsoleevent;      imonitorpublishing publishcallback = null;     writeconsoleeventhandler writeconsolehandler = null;      public void subscribe(int processid)     {         publishcallback = operationcontext.current.getcallbackchannel<imonitorpublishing>();         writeconsolehandler = new writeconsoleeventhandler(publishwriteconsolehandler);         writeconsoleevent += writeconsolehandler;         //publishwriteconsole("winning")     }      public void unscubscribe(int processid)     {         writeconsoleevent -= writeconsolehandler;     }      public void publishwriteconsole(string text)     {         serviceeventargs se = new serviceeventargs();         se.text = text;         writeconsoleevent(this, se);     }      public void publishwriteconsolehandler(object sernder, serviceeventargs se)     {         publishcallback.writeconsole(se.text);     } }

the services host fine , able add service reference in client application. if uncomment "winning" line triggers client's callback method fine (after time). leads me believe subscription , callbacks working great.

my question is, @ various points in host application wish print subscribed clients console via publishwriteconsole callback method. how make function call in host application need connect service own application hosting? i'm alot confused appreciated.

here relevant app.config bits

<services>   <service behaviorconfiguration="monitor.monitorsubscriptionservicebehaviour"            name="monitor.monitorsubscriptionservice">     <host>       <baseaddresses>         <add baseaddress="net.tcp://localhost:5050/monitor"/>       </baseaddresses>     </host>     <endpoint address=""  binding="nettcpbinding" bindingconfiguration="" contract="monitor.imonitorsubscribing">       <identity>         <dns value="localhost"/>       </identity>     </endpoint>     <endpoint address="mex" binding="mextcpbinding" contract="imetadataexchange"/>   </service> </services> <behaviors>   <servicebehaviors>     <behavior name="monitor.monitorsubscriptionservicebehaviour">       <servicemetadata httpgetenabled="false"/>             <servicedebug includeexceptiondetailinfaults="false" />     </behavior>   </servicebehaviors> </behaviors>

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 ...
