VS C++ Issue with InvokeRequired / delegate void - c++-cli

Question

I am new to C++ and Im using VS2010.
Could someone check the code below and help to solve it? Everytime the function UpdateDataGrid(unsigned char CANPacket[15])
is called the following message is shown in a new window and the application closes.
An unhandled exception of type 'System.ArgumentException' occurred in System.Windows.Forms.dll
Additional information: Object of type 'System.Byte' cannot be converted to type 'System.Byte*'.
I have to use unsinged char data type and not String^ in this project.
Is there any way to correct my code?
//Piece of my code
namespace VCCDC {
using namespace System;
using namespace System::ComponentModel;
using namespace System::Collections;
using namespace System::Windows::Forms;
using namespace System::Data;
using namespace System::Drawing;
using namespace System::Threading;
public ref class Form1 : public System::Windows::Forms::Form
{
delegate void UpdateDataGridCallback(unsigned char CanPacket[15]);
private: void UpdateDataGrid(unsigned char CANPacket[15]) {
if (this->dataGridView1->InvokeRequired) {
UpdateDataGridCallback^ d = gcnew UpdateDataGridCallback(this,&VCCDC::Form1::UpdateDataGrid);
this->Invoke(d,gcnew unsigned char(CANPacket[15]));
}
else {
//Update dataGridView1 with new data
}
}
}
}]

Answer 1

Change the line
this->Invoke(d,gcnew unsigned char(CANPacket[15]));
to
this->Invoke(d,CANPacket));
You already have an unsigned char pointer, pass it through. With gcnew you intent to create another one, which is unnecessary.
Also error caused by this gcnew line. You have to construct the Byte* with a Byte parameter. Yours is Byte* too.
