c++ - Difference between is_same and mpl::same_as in boost -


मुझे boost :: is_same और boost :: के बीच का अंतर देख नहीं सकता एमपीएल :: same_as । क्या कोई शायद इन्हें बताता है और जहां केवल विशिष्ट प्रकार का उपयोग किया जा सकता है।

प्रभावी रूप से, कुछ भी नहीं। यदि आप वास्तव में mpl :: same_as को देखते हैं, इसमें is_same शामिल होता है और फिर इसे सीधे उपयोग करता है

ध्यान दें कि & lt; type_traits & gt; सी ++ 11 के रूप में मानक पुस्तकालय का हिस्सा है, और इसमें std :: is_same शामिल है (जो वास्तव में कार्य करता है को बढ़ावा देने में उपर्युक्त दो फ़ंक्शन की तरह)।

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!

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
