Thread function and class member function and variable access

All:
There are some discussions about this topic back to 2003. I still
don't really clear about the solution. I am using .NET 2005 MFC
application. I have a class definition as follows. Inside thread
function, I want to call private variable or public function from the
same class, I got the same error C2597: illegal reference to non-static
member 'foo::iValue', 'foo::ErrorReport'. How do I do to let my thread
function that can call class member variable and function?

By the way, this class is initalized in view object from MFC framework.

I have a class as follows:

#pragma once
class foo
{
public:
    foo();
    ~foo();

    void StartThread(void);
    static UINT ThreadProc(LPVOID pvData);

    void ErrorReport(CString csError);
private:
    int iValue;
};

#include "stdafx.h"
#include "foo.h"

foo::foo()
{
    iValue = 10;
}

foo::~foo()
{
}

void foo::StartThread(void)
{
    CWinThread* pwt;
    pwt = AfxBeginThread(this->ThreadProc, NULL);
}

UINT foo::ThreadProc(LPVOID pvData)
{
    CString csMsg = _T("i = ");
    csMsg += iValue;
    AfxMessageBox(csMsg);

    ErrorReport(_T("Error: ThreadProc"));
    return 1;
}

void foo::ErrorReport(CString csError)
{
    AfxMessageBox(csError);
}

Thank you so much for the help
