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; }

It has been transmitted) where the path is null MS Access Along with, it works fine: Update Articles Join the Inner Articles at articles_tmp articles.id = articles_tmp.id SETP articles.path = articles_tmp.path Can anyone help? Sin CE SQL Server Syntax, which I provided, was not working, here this solution With whom I have come. A little modification of your original query, but with my "correlation" suggestion added.

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ
