大大们帮帮忙，wince内timeSetEvent调用有关问题

大大们帮帮忙，wince内timeSetEvent调用问题
编译的时候产生
error C2664: 'timeSetEvent' : cannot convert parameter 3 from 'void (__cdecl CCamera_AppDlg::* )(UINT,UINT,DWORD,DWORD,DWORD)' to 'LPTIMECALLBACK'
下面附相关代码
void CCamera_AppDlg::OnBnClickedBtnRecord()
{
UINT TimerID_1000ms;
TimerID_1000ms= timeSetEvent(1000,1,&CCamera_AppDlg::MyCallBack,0,TIME_PERIODIC);

}
void PASCAL CCamera_AppDlg::MyCallBack(UINT wTimerID, UINT msg,DWORD dwUser,DWORD dwl,DWORD dw2) 
{。。。。}
在头文件里定义：
class CCamera_AppDlg : public CDialog
{......
......
public:
afx_msg void OnBnClickedBtnPreview();
afx_msg void OnBnClickedBtnSnap();
afx_msg void OnBnClickedBtnRecord();
  void PASCAL MyCallBack(UINT,UINT,DWORD,DWORD,DWORD);
};
我怀疑是和在类里创造线程的时犯的错误类似。但是又不肯定。能不能请大大帮忙看看怎么解决，在此感激不尽。
PS:我把上面强制转换改成TimerID_1000ms= timeSetEvent(1000,1,(LPTIMECALLBACK)CCamera_AppDlg::MyCallBack,0,TIME_PERIODIC);
结果产生
error C2440: 'type cast' : cannot convert from 'overloaded-function' to 'LPTIMECALLBACK'
望各位大大给以提点，再次的感谢！

C/C++ code

class CCamera_AppDlg : public CDialog{......public:   static void PASCAL MyCallBack(UINT,UINT,DWORD,DWORD,DWORD);   void MyCallBack2(UINT,UINT,DWORD,DWORD);};void PASCAL CCamera_AppDlg::MyCallBack(UINT wTimerID, UINT msg,DWORD dwUser,DWORD dwl,DWORD dw2) {   ((CCamera*)dwUser)->MyCallBack2(wTimerID, msg, dw1, dw2);}void CCamera_AppDlg::MyCallBack2(UINT wTimerID, UINT msg,DWORD dwl,DWORD dw2) {   MySnap();}void CCamera_AppDlg::OnBnClickedBtnRecord(){TimerID_3000ms= timeSetEvent(500,1,MyCallBack,(DWORD)this,TIME_PERIODIC);}

1. member function 需要 instance, 故僅能用 static member function.
2. static member function 沒有 instance, 所以在 call 它時, 要想辦法將 this pointer 傳進去.
