A pointer-to-member is not valid for a managed class

[R. Irudezu]

I know this problem is pretty common but in my case things are some specific. I will explain my problem clearly.

First, developmen environment: Visual C++/CLR Desktop Application.

I have a native dll imported to project and a header.

test.h:


#pragma once

#include <stdint.h>

struct config;

typedef void (* testCallBack)(TestHandle *conn, uint64_t timeStamp,
uint8_t *frameData, uint32_t frameDataLen,
TestFace *faces, uint32_t faceCount);


struct config
{
testCallBack liveCallBack;
};


I wrote a function into

public ref class

function is:

void onFrame
(
TestHandle *conn, uint64_t timeStamp,
uint8_t *frameData, uint32_t frameDataLen,
TestFace *faces, uint32_t faceCount)
)
{
/*
* Some Stuff with parameters here
*/
}

and a button function is like:

private: System::Void testBtn_Click(System::Object^ sender, System::EventArgs^ e)
{
config cfg;
cfg.testCallBack = onFrame;
//It gives error here, under he onFrame, a pointer-to-member is not valid for a managed class...
// How can i solve this, please help about this.
}
