"C# dllimport'ing complex datatypes across platforms?",
"So I'm writing a wrapper in C# for a C dll. The problem is several of the functions use complex datatypes e.g.:\n\nComplexType* CreateComplexType(int a, int b);\n\n\nIs there a way I can declare a valid C# type such that I can use dllimport?\nIf I were doing a Windows-only solution I'd probably use C++/CLI as a go-between the native complex type and a managed complex type.\n\nI do have access to the source code of the C dll, so would it be possible to instead use an opaque type (e.g. handles)?"

Any hints ?\n\nEdit: I managed to get it working by calling matlab-shell-run-command. The caveat here is that it only works if the starting sequence is: open your unit-test.m file, from that file run M-x matlab-shell (this way matlab starts with the current working directory in the tests directory) and then you can use the above binding."

"Why does implicit conversion not work in accumulate?",

I know that conversion from const char * to string is not explicit, so we can pass const char * parameter to calls in which a string type is required. This can be proved by the above test_string function. But when I did the same thing in accumulate, the compiler complain:\n\n\nerror C2440: '=': cannot convert from 'std::basic_string<char,std::char_traits<char>,std::allocator<char>>' to 'const char *'\n\n\n\nThe code works only when I replaced \"\" with string(\"\"). I don't understand why the implicit conversion works for my custom function but does not work in accumulate. Can you explain that? Thanks a lot.\n\nPS: I am using Visual Studio 2015."

"I am getting the following error message when compiling or attempting to run my application on Windows 7 64 bit. I've scoured the Internet and many people have the same error message. However, none of the solutions address my problem or situation. I am using Visual Studio 2010.\nError message\n\nError 38 Could not load file or assembly 'file:///D:/Projects/Windows Projects/Weld/Components/FileAttachments/FileAttachments/FileAttachments/bin/x86/Debug/FileAttaching.dll' or one of its dependencies. An attempt was made to load a program with an incorrect format. Line 1212, position 5. D:\\Projects\\Windows Projects\\Weld\\Weld\\Weld.UI\\frmMain.resx 1212 5 Weld.UI\n\nDescription\nOK, so I have two projects, a UI project and a FileAttachment project. The UI project has a reference to the FileAttachment project. When I compile the UI project in "Any CPU" mode, everything works fine, and it runs. I assume 'Any CPU' will run in 64-bit mode when I compile as that is the platform I am using.\nI want to run/compile as x86, so I try to do that. I change the configuration for all projects to x86 and verify that these configurations are compiling to x86. I compile and get the error as stated above.\nI find it odd that it compiles and works fine in 64-bit but not 32-bit. However, when compiled and deployed to users as 'Any CPU', if these users have x86 it still works for them without any problems. I just can't compile or run as x86 on my PC. Again, I can compile as Any CPU and deploy to a 32-bit PC without any problems.\nNeither projects are referencing any 64-bit-only DLL files. Both projects are verified to be targeting 32-bit DLL files and .NET Framework assemblies.\nI need to compile and run this locally under 32-bit mode. I need JIT edit/continue, among other things.\nHere is the line of code in the resx file that is causing the problem:\n <data name="ImageList1.ImageStream" mimetype="application/x-microsoft.net.object.binary.base64">\n....{mime data}....\n </data>\n\nThe resx file is verified to be generated for .NET 2.0 and is only referencing .NET 2.0 assemblies and not .NET 4.0 versions.\nHow can I fix this problem?

I've found a manually workaround, but I need to do this as a command line with command Prompt. Someone know how ? Thx."

"How can I configure IdentityServer4 (DotNet Core) to work in Nginx reverse proxy",
"I've published my API, ID server STS and web ui on separate docker containers and I'm using a nginx container to act as the reverse proxy to serve these app. I can browse to each one of them and even open the discovery endpoint for the STS.

"Animations are clipped to ViewGroup bounds in Android 4.3 and below?",
"I'm working on a custom ViewGroup which draws some animations in the dispatchDraw() method.\n\nI came across this in my Google search: https://groups.google.com/forum/#!topic/android-developers/dZ0Yxjz3v7o\n\nAnd I have set clipChildren=\"false\" inside my XML to both the parent and the grandparent view of my custom ViewGroup. However, this fixed the clipping of the animations drawing on Android 4.3 and above. Android 4.0 - 4.3 still clips the View animations to its bounds.\n\nAny help would be appreciated."

"Shell access to Persistent Volume in Google Cloud",
"I would like to get shell access to the Persistent Volume I created on the Google Cloud Platform. \n\nI tried using Google Cloud Shell for this. But to be able to do that I need to attach the Persistent Volume through the gcloud commands, and the command requires the instance name. But I don't see the instance name of the Google Cloud Shell when I list the instance names (in gcloud). \n\nIs it possible to get shell access over Google Cloud Shell to the persistent disks? If not how can I get access to the Persistent Volume that I created?"

"Performance orientated message callback solution in c++",
"I am trying to develop a p2p distributed concurrent programming solution in C++. For higher throughput I have observed that \"to and fro\" concurrent and scalable network solution is required as in actor model provided by AKKA. Unfortunately there is no reliable solution for actor model available in C++. libcppa is available but only in Beta quality. Is there any scalable and concurrent solution do same in zeroMQ or Boost.asio etc? Programatically I want to do following very fast and in scalable fashion.\n\nSuppose I have a cluster of N nodes which contain separate set of objects. When a node require a remote object it sends a request and get backs a object as a response. Currently I do it in following manner:\n\nRequest req = Network.request(Node x, objectId id);\nreq.waitforResponse( ); //Implemented through Conc-Hashmap of requests and wait & signal\nObject obj = req.response().getObject();\n// Do sth with object.\n\n\nI don't want to implement last two lines of codes myself. I want it to be done by networking library itself. Best solution will be if I can get \"req\" object in some sort of \"Future\" data structure which will block only on calling getObject(). I think it is a very generic problem and there should be some good open source solution available for it. If not please suggest some more efficient solution other than Concurrent hashmap (C++ Intel threads) based approach. Unfortunately my good amount of googling on it did not pay much."
