managed-c++

I'm trying to write an application in Managed C++, but I cannot work out how to declare an array of strings. String^ linet[]; throws an error 'System::String ^' : a native array cannot contain this managed type So I suppose there's a different way to do this for managed data types. What exactly is it? Do you really mean Managed C++? Not C++/CLI? Assuming you're actually using C++/CLI (because of the error message you posted), there are two ways to do this: array<String^>^ managedArray = gcnew array<String^>(10); will create a managed array, i.e. the same type as string[] in C#. gcroot<String^>

Closed. This question is off-topic . It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 5 years ago . I have recently inherited a program written in Managed C++ from some guy who just retired. After spending some time digging through it, I can honestly say that at least 95% of it belongs on thedailywtf . However, I am now tasked with modifying it and porting it over to a language I'm comfortable with. The program itself takes in many many parameters (50+) read in from a file and performs a series of calculations

Is there a way to add assembly attributes to a Managed C++ assembly? In a typical C# project, there is usually a line of code in the AssemblyInfo.cs file like the following one: [assembly: AssemblyTitle("Some Assembly")] I have a private assembly attribute that I want to add (not one of the version attributes that could be added through a resource file), and I am not sure if this is possible. It is possible - the easy way is to add an AssemblyInfo.cpp file and put: #include attributes.h //your attribute decl [assembly: MyCustomAttribute()]; It can be in any file you want, though. edit - added

In my experience, .NET is 2 to 3 times slower than native code. (I implemented L-BFGS for multivariate optimization). I have traced the ads on stackoverflow to http://www.centerspace.net/products/ the speed is really amazing, the speed is close to native code. How can they do that? They said that: Q. Is NMath "pure" .NET? A. The answer depends somewhat on your definition of "pure .NET". NMath is written in C#, plus a small Managed C++ layer. For better performance of basic linear algebra operations, however, NMath does rely on the native Intel Math Kernel Library (included with NMath). But

I have a callback that is called through a delegate. Inside it I will need to treat the buffer data that arrive from a record procedure. Normally in a unmanaged context I could do a reinterpret_cast on dwParam1 to get the object reference. But in a manged context how can I cast a DWORD_PTR to a managed object ref? static void WaveInProc(HWAVEIN hwi, UINT uMsg, DWORD_PTR dwInstance, DWORD_PTR dwParam1, DWORD_PTR dwParam2) { ControlLib::SoundDevice^ soudDevice = ?cast_native2managed?(dwParam1); Here ya go, more or less what gcroot (per my comment above) does: using namespace System; using
