In the case where I am working with an existing C library, I prefer PInvoke. PInvoke, while a bit tedious and troublesome at times, is a fairly well understood technology that has an ever growing set of tools and internet documentation available. Generally speaking, whatever problem you run into, there is already a sample available … Read more
Open the command prompt as administrator and enter following commands: reg DELETE “HKLM\Software\Microsoft\StrongName\Verification” /f reg ADD “HKLM\Software\Microsoft\StrongName\Verification\*,*” /f reg DELETE “HKLM\Software\Wow6432Node\Microsoft\StrongName\Verification” /f reg ADD “HKLM\Software\Wow6432Node\Microsoft\StrongName\Verification\*,*” /f
It’s a managed pointer – while * marks a pointer to an object that is unmanaged, ^ points to a garbage collected object (handled by the framework). Read this for more information about the way pointers are handled in .NET.
OK, found it, after a lot of hassle: to return null, just do return Nullable<double>(); to return non-null: return Nullable<double>(12321); It is important to declare the return value as Nullable<double> and not Nullable<double>^, as if you do it, when using other languages as C# and vb.net, you’ll see the type as ValueType instead of double?.
Simple way assuming class Foo: Create a C++/CLI project, call this FooWrapper. Make FooWrapper depend on the unmanaged dll (however you normally would). Create a managed class ManagedFoo which contains a single private instance field of type Foo*. provide public wrapping functions in ManagedFoo which forward on to the underlying instance field. Optionally (though recommended): … Read more
It’s a generated file for designer efficiency, you can ignore it in source control: File created by Microsoft Visual C++, a software development application; stores the binary representation of a resource included with the project; enables the application to load resources more quickly. http://fileinfo.com/extension/aps
System::String has a constructor that takes a char*: using namespace system; const char* charstr = “Hello, world!”; String^ clistr = gcnew String(charstr); Console::WriteLine(clistr); Getting a char* back is a bit harder, but not too bad: IntPtr p = Marshal::StringToHGlobalAnsi(clistr); char *pNewCharStr = static_cast<char*>(p.ToPointer()); cout << pNewCharStr << endl; Marshal::FreeHGlobal(p);
I have gotten it to work as follows: Use XML style comments for your C++/CLI header entries. This means the full XML comment is required (triple-slash comments, <summary> tag at a minimum) Make sure that the C++ compiler option Generate XML Documentation Files is on. This should generate an XML file with documentation with the … Read more
You are correct. Unfortunately it has been dropped. You can check this opened issue on Microsoft’s Connect website. I’ll just quote them for the sake of the answer: Unfortunately in this release we had to cut the intellisense support for C++/CLI due to time constraints. If you want to get some intellisense like quick info … Read more
C++/CLI itself doesn’t support a real ‘out’ argument, but you can mark a reference as an out argument to make other languages see it as a real out argument. You can do this for reference types as: void ReturnString([Out] String^% value) { value = “Returned via out parameter”; } // Called as String^ result; ReturnString(result); … Read more
