c++ - Convert array<String^>^ to std::vector<std::string> -


मैं एक प्रबंधित सरणी & lt; स्ट्रिंग ^ & gt; ^ से std: : वेक्टर & LT; std :: स्ट्रिंग & gt; । निम्नलिखित कोड संकलित नहीं होता है और मुझे पता नहीं क्यों अजीब बात है, अगर मैं उदाहरण के लिए एक इंट का उपयोग करता हूं तो यह ठीक काम करता है। पहले से धन्यवाद: 

  std :: vector & lt; std :: string & gt; कनवर्टऑन मैनेजेटेड (सरणी & lt; स्ट्रिंग ^ & gt; ^ ar) {सिस्टम :: IntPtr; सिस्टम :: रनटाइम :: इंटरऑप सर्विसेज :: मार्शल का उपयोग कर; std :: वेक्टर & LT; std :: स्ट्रिंग & gt; वेक्टर (AR- & gt; लंबाई); मार्शल :: कॉपी (एआर, 0, आईटीपीटीआर (& amp; वेक्टर [0]), आर-> gt; लंबाई;); वापसी वेक्टर; }

मार्शल :: कॉपी का कोई अधिभार नहीं है स्ट्रिंग पैरामीटर के सरणी के साथ।

सरणी तत्व पर फेरबदल करना और एक-एक-एक काम को परिवर्तित करना। 

  #include & lt; msclr / marshal_cppstd.h & gt; std :: वेक्टर & LT; std :: स्ट्रिंग & gt; कनवर्टऑन मैनेजेटेड (सरणी & lt; स्ट्रिंग ^ & gt; ^ ar) {std :: vector & lt; std :: string & gt; वेक्टर (AR- & gt; लंबाई); के लिए (int i = 0; i & lt; ar-> gt; लंबाई; ++ i) {ऑटो एस = आर [i]; वेक्टर [i] = msclr :: इंटरॉप :: मार्शल_आस & lt; std :: string & gt; (एस); } वापसी वेक्टर; }

Python Equivalent for matlab cart2pol and pol2cart -

I would like to use pol2cart and cart2pol for two functions in MATLAB. Is there an equivalent Python Function? Or if we can define work? For example, I tried to use the CeMatePactor function, but it only accepts one argument, I have 2 arguments to cross the polar and REC function. P> I have tried to use this function for cart2pol: def cart2pol (x, y): theta = atan2 (y, x) rho = Sqrt (x ** 2 + y ** 2) returns (theta, ro) thanks

Docker - Tomcat and PostgreSQL containers in same host - No Route to host -

I have a web application running on Tomcat and has started the container using the command, Docker run -d -p 8080: 8080 tveuser / tve-repository: tve-services I also run a PostgreSQL container on the same host using the following command am: Docker run-D-P 80: 80-P-5432: 5432 Tivejhr / Tive-repository: TV-post-Jiaracl I Verify that PostgreSQL is running using phpPgAdmin but Neither could it find the tomato to connect. 'Docker PS' also tells me that both the containers are up and running. I connect the web entry to the database through the TOKamet Reference.XML which contains the entry & lt; Parameter Name = "abc.connection.url" value = "jdbc: postgresql: //1.2.3.4: 5432 / dbname" /> Where 1.2.3.4 is the Dockers Host IP in which the Container is Running. But when I run the Tomcat Container, I get the following error: Org.postgresql.util.PSQLException: The connection attempt failed. On Org.postgresql.core.v3.ConnectionFactoryI...
