问题 So, I've written a web service in c#, which has a method for signing a hash. This web service is a WCF Service application. Then, I've created a c# Console application where I've written a function to consume this web service. The declaration of the function which calls the web service is that: class Program { public byte[] callWS(string alias, byte[] myHash,string myPassword) { IhashSignSVCClient client = new IhashSignSVCClient(); byte[] signedData= client.SignandReturn(alias, myhash,

问题 Okay. So i am using Visual Studios 2010 -> Visual C++ and the .NET Framework (Windows Forms Application) and when i try to hash a string with the hashlib++ i get multiple LNK errors. This is hashlib++ : http://hashlib2plus.sourceforge.net/ This is my code for the hash: //I have more Includes but according to http://hashlib2plus.sourceforge.net/example.html these are the only ones required for hashlib++ so these are the ones i am putting on display. #include <string> #include <iostream>

问题 I have a system comprising a C# UI, a C++/CLI mixed mode interop wrapper, and some native c++ projects. What I need to do is set up a system such that the native c++ code can send a log message, and the UI can report it. I set up a native IObservable using this as a template, but then the C# code can't be an observer. My thought was to set up another observer pattern in C++/CLI, which observes the native observer, and to let the C# implement that. I used this as a template but I'm struggling

问题 I've been struggling for hours trying to figure out how to use resources in C++/CLI. I've messed around with the resource.h/app.rc files along with the managed resx files to no avail. I just have a couple PNG images that I would like to use with a PictureBox, but I can't seem to figure out how to setup the resources... Thanks for your help, Alex 回答1: create a windows forms project add new resource file (resx) to the project open that file, the resource editor appears in the top left corner

问题 Right now I have button on a usercontrol. Clicking that button will launch a window as follows, private void Button_Click(object sender, RoutedEventArgs e) { this.Effect = new BlurEffect(); dlg = new WidgetWindow(); dlg.Owner = Window.GetWindow(this); dlg.Show(); this.Effect = null; } Now please see the Image. Whenever I click outside the widget window i.e. anytime I click on the grayed out area of the usercontrol, I want the circular widget window to close. I am trying to raise an event for

问题 I have a software that accepts a C dll as plugin. The dll export two functions: init and quit. To test how the plugin works, I wrote three projects after the NativeWrapper concept: a managed library in C++ (dll), a native wrapper in C++ (also dll, that exports the init and quit functions) and a C++ test program. For now I am just testing the init function. All these are built and run inside VS 2013 without any issue. However, When I plug the two dlls in with the said software, it stops

问题 I already have found useful answers why it shouldn't be possible at all: Why does C# limit the set of types that can be declared as const? Why can't structs be declared as const? The first one has a detailed answer, which I still have to re-read a couple of times until I fully get it. The second one has a very easy and clear answer (like 'the constructor might do anything, so it had to be run and evaluated at compile time' ). But both refer to C#. However, I am using C++/CLI and have a value

问题 I have a class in C++/CLI that uses unmanaged resources (a HANDLE for a native thread (i.e. from CreateThread()) and an LPVOID for a fiber from CreateFiber/ConvertThreadToFiber). Under the advice I got from MSDN I'm cleaning up the unmanaged resources in the finalizer (!Fiber()), and the destructor (~Fiber()) is calling the finalizer. Here's the code: Fiber::~Fiber () { this->!Fiber(); } Fiber::!Fiber () { if (thread!=NULL) { delete thread; thread=NULL; } if (fiber!=NULL) { DeleteFiber(fiber)

问题 Does somebody know, are there any plans or works to add ECMA standardized C++/CLI language support to GCC (which would emit IL code)? This question was partially discussed in SOF (Does Mono .NET support and compile C++ / CLI?), but firstly I'm not sure that this imaginary project should be realized as a part of Mono project instead of core GCC one, and secondly I'm interested in novel information on this subject. 回答1: I know of no such work personally (and my opinion of most ECMA standards

问题 I'm looking for a way to return the reference to another object that is a member of a managed object. This can be easily achieved in C++, but is a challenge for C++/CLI wrapper to be used with C#. Below is reproducible scenario (it's a lot of code, but it's all very easy, just demonstrating the problem) C++ classes: class NATIVEAPI NativeSlave { public: NativeSlave() : x_( 0 ), y_( 0.0 ) {} NativeSlave( int x, double y ) : x_( x ), y_( y ) {} int x_; double y_; }; class NATIVEAPI NativeMaster
