porting

问题 I have a C++\MFC application written in Visual Studio 2003 SP1 links to an external static library "SomeExtStaticLib.lib". I also include the header files provided with "SomeExtStaticLib.lib" to create the objects in my application. SomeExtStaticLib.lib is a static library built with VC6. Now, I am migrating my application to Visual Studio 2008. I have very basic question. Should I also migrate the "SomeExtStaticLib.lib" to VS2008 compiled one? When I tried to use this VC6 compiled

问题 A pointer * and a reference & in Rust share the same representation (they both represent the memory address of a piece of data). What's the practical differences when writing code though? When porting C++ code to Rust can they be replaced safely (c++ pointer --> rust pointer, c++ reference --> rust reference ) ? 回答1: Use references when you can, use pointers when you must. If you're not doing FFI or memory management beyond what the compiler can validate, you don't need to use pointers. Both

问题 We are porting an ASP.NET MVC 4.x application to ASP.NET Core 3.1 . The current application is using EF 6.x DB first approach. As a part of this migration we are going to use EF Core 3.1 as an alternative to the current EF 6.x . So the question is: Does EF Core 3.1 support DB First approach? If not, what are the options? Are we left with only code first approach? Appreciate your helps. 回答1: Yes. It supports DB First Approach since .NET Core 1.0 until now. You need to download 4 from nugets

问题 I'm trying to port the following Java code to a C# equivalent: public static String encrypt(String value, String key) throws InvalidKeySpecException, NoSuchAlgorithmException, NoSuchPaddingException, InvalidKeyException, IllegalBlockSizeException, BadPaddingException { byte[] bytes = value.getBytes(Charset.forName("UTF-8")); X509EncodedKeySpec x509 = new X509EncodedKeySpec(DatatypeConverter.parseBase64Binary(key)); KeyFactory factory = KeyFactory.getInstance("RSA"); PublicKey publicKey =

问题 I've got a little C++ project that was developed for Win32 and I want to port it to OSX. The code uses functions like _bittest and _bittest64 but I haven't found same functions in the XCode header files. What could be an alternative for these functions? May be there are good working polyfills. The project is a legacy indeed, no extra performance is required at the moment. 回答1: The _bittest and _bittest64 symbols are compiler intrinsics, that emit Bit-test instructions, specifically x86 bt, to

问题 I have a GUI which I created using WPF I not want to port this so it's available for use on mac OS X. I heard mono can be used but it looks like they don't have any support for WPF's as of right now so any suggestions would be great Thanks. 回答1: .NET Core 3.0 has WPF but it works only for Windows platform , so there is no build-in support for multi-platform desktop GUI. You could try port WPF application using Avalonia, but I never tried it. Avalonia works with .NET Core 2.0, .NET Standard 2

问题 What is the equivalent of Linux's /proc/cpuinfo on FreeBSD v8.1? My application reads /proc/cpuinfo and saves the information in the log file, what could I do to get similar information logged on FreeBSD?
