I'm novice in .net c++ and trying to create class looking like: public ref class Klient { public: Klient(){} // zmienne static DWORD klienty[41][2]; static int i = 1; static DWORD* pid; static HANDLE* handle; //funkcje }; but MSV says that: error C4368: cannot define 'klienty' as a member of managed 'Klient': mixed types are not supported What's wrong with this code? You can have .NET basic data types as members of your managed class (static int i), or pointers to anything unmanaged (DWORD* pid, HANDLE* handle), but you're not allowed to have an unmanaged object directly, and the array of

I have a win32 application using a C# library . The C# library has a method where the Action<T> delegate is a parameter as shown: public NetSocket(Action<int, int, string> action) I have a ref class in the win32 application with a method that matches the Action delegates signature. How exactly do I pass this method as the Action parameter in the NetSocket method listed above? Ben your solution seem to work but there was a compile error on matching the System:Sting ^ input parameter of the action delegate method in the win32 application to the String input parameter of Action delegate in the C#

This post says that it is possible to turn off the CLR flag for an individual .cpp file. From the post: You can set /CLR on or off in each .cpp file individually. Turn it on for the whole project,. as you have done, then turn it off for the files containing only native (unmanaged) code. When you have the VC++ procject properties dialog open, you can still click on files/projects in the solution explorer to change the scope that you're working on. Click on the unmanaged .cpp file to set options for just that file. Is this true? I can't figure out how to do it through the property pages for my C

I'm trying to send an image from C++ to C# with an interop (marshaling) of C++ managed. image->getStream() return a const char* from a string. I'm having exception with my Marshal::Copy function. An unhandled exception of type 'System.AccessViolationException' occurred in mscorlib.dll Additional information: Attempted to read or write protected memory. This is often an indication that other memory is corrupt. Am I doing the right thing for the copy from a const char* to a byte array ? My dll is compiled with ASCII char set in VS2010. array<System::Byte>^ OsgViewer::getLastImage() { array< Byte

I get this error when I attempt to load a mixed mode C++/CLI assembly into SQL Server 2012: CREATE ASSEMBLY [Test] AUTHORIZATION [dbo] from 'H:\test.dll' WITH PERMISSION_SET = SAFE Msg 6544, Level 16, State 1, Line 1 CREATE ASSEMBLY for assembly 'Test' failed because assembly 'Test.dll' is malformed or not a pure .NET assembly. Unverifiable PE Header/native stub. Solomon Rutzky Mixed-mode Assemblies are not allowed in SQLCLR Assemblies; only pure MSIL Assemblies are allowed. This is implied in the MSDN documentation for CREATE ASSEMBLY in the Remarks section: Assembly Validation SQL Server

I am writing a C# library to be used by native C++ application. I am using C++/CLI as the Interoperability mechanisim. I require to pass a callback function from C++ to C# (using C++/CLI as the intermediate layer). C# library needs to call the C++ function with a zero terminated string of wide characters; i.e. the prototype of the callback function is Func(LPCWSTR pszString); There are other parameters but they are immaterial for this discussion. I searched net and found Marshal.GetDelegateForFunctionPointer Method wich I can use. The problem with this is that it converts System.String from C#

In C#, I can specify a fixed sized buffer using the fixed keyword, like so: public unsafe struct StructWithFixedBuffer { public fixed char FixedBuffer[128]; } how would I express the same thing in C++/CLI? One of the C++/CLI developer blogs had code for a template solution to this, I'll try to find a link. Ahh, found it. It's called inline_array . The C# syntax was added as a way to express the C++ syntax you've know forever. :) public: wchar_t FixedBuffer[128]; Quote: size of the 128 element char array is 256 bytes. Fixed size char buffers always take two bytes per character, regardless of
