问题 Microsoft recently released tools and documentation for its new Phone 7 platform, which to the dismay of those who have a big C++ codebase (like me) doesn't support native development anymore. Although I've found speculation about this decision being reversed, I doubt it. So I was thinking how viable would be to make this codebase available to Phone 7 by adapting it to compile under C++/CLI. Of course the user interface parts couldn't be ported, but I'm not sure about the rest. Anyone had a

问题 Motorola just released an x86 based Android phone. I'm a little confused as to how native apps/libraries written for ARM(netflix for example) can run on this phone. I'd be grateful if someone could explain. 回答1: Yes, ARM native code runs on Intel x86 using an emulation feature named Houdini What this library does is reads ARM instructions on the fly and converts them to equivalent x86 instructions. This is the reason why many apps may work as is on x86 without actually having to build an

问题 Having trouble carrying out a build I am trying to complete. I have the build 1 and build 2 complete. Build 1 - A simple blank screen with two text boxes with alignment constraints Build 2 - When application is run it calls the native back camera of an IOS device. My third build is these two previous builds together as one, where the native camera shows a live video feed and over layed is the two text boxes with their alignment constraints. I am unsure how to bring the two bits of code

问题 I used the following simple logic to answer a question like this one: 1: if(a) // 1 operation 2: if (b) // 1 operation and 1: if(a && b) // 1, 1(&&), 1 => 3 operations. So, 2 operations versus 3, but in the first example the compiler needs to call another instruction to be executed. Is this logic true?. Does it depend on the compiler?. Does calling an empty instruction like only ; cost the compiler some noticable time?. This also discuss the same problem but not considering this logic. Please

问题 I am trying to check whether the Native app is installed or not , If it is not I have to prompt the user to download it from the webpage. For chrome I used to achieve by checking the error messages from runtime.LastError. However in case of Firefox it gives error only in console No such native application extension_name and not catching it in the runtime.LastError method. Is there any way that we can identify whether corresponding Native app is installed or not ? I am facing issue when Native

问题 I’m installing scrypt (https://www.npmjs.com/package/scrypt) from npm. The installation involves a node-gyp build step that builds a native node.js extension. When I then start my app, it fails with the following error: node index.js module.js:568 return process.dlopen(module, path._makeLong(filename)); ^ Error: /package/host/localhost/gcc-4/lib64/libstdc++.so.6: version `GLIBCXX_3.4.21' not found (required by /home/xxxx/xxxx/node_modules/scrypt/build/Release/scrypt.node) at Error (native) at

问题 I'm building a c++ tetris game (not c++ .Net). I feel my controls are weird. I want to make it so that when user presses one of the arrow keys, about 10ms of holding it down will start the repeat function windows has. It is set to about 500ms by default, and it is too laggy for my game. How can I set the speed at which it changes from the keydown to the repeat keydown? Not how many times / sec it repeats. Thanks *what I want to do is change the repeat delay to short In control panel in

问题 I have managed to encrypt data in native code using the Crypto API and decrypt this in .NET (C#) code, using RC2 algorithm and SHA for creating a key. This is the native code (Delphi in this case): // Get handle to CSP If Not CryptAcquireContext(hCryptProv, nil, nil, PROV_RSA_FULL, 0) Then If Not CryptAcquireContext(hCryptProv, nil, nil, PROV_RSA_FULL, CRYPT_NEWKEYSET) Then ShowMessage('CryptAcquireContext '+IntToStr(GetLastError())); // Create a hash object If Not CryptCreateHash(hCryptProv,
