EnumFontFamiliesProc遇到了麻烦

问题描述

大家好！
我有麻烦，请帮帮我！
我是MFC编程的初学者.我已经使用字体系统对程序进行了编码.通过一本书，我知道了使用两个功能列出字体系统的方法:

Hi every body!
I have a trouble, help me please!
I am a beginner in MFC programming. I have coded a progam using font system. Through a book, I knew the way to lists font system by using two functions:

int CALLBACK EnumFontFamExProc(ENUMLOGFONTEX *lpelfe, NEWTEXTMETRICEX *lpntme, DWORD nFontType, LPARAM lParam)
{
    CFontDlg *pWnd = (CFontDlg*) lParam;
    //CFontDlg is the class base on the interface-dialog of my program
    pWnd->m_lbFont.AddString(lpelfe->elfLogFont.lfFaceName);
    //m_lbFont is a variable to control ListBox, which on I want to lists font system
    return 1;
}

void CFontDlg::FillFontList(void)
{
    LOGFONT lf;
    lf.lfCharSet = DEFAULT_CHARSET;
    lstrcpy(lf.lfFaceName, _T(""));
    m_lbFont.ResetContent();
    CClientDC dc(this);
    ::EnumFontFamiliesEx((HDC) dc, &lf, (FONTENUMPROC) EnumFontFamExProc, (LPARAM) this, 0);
}

当我生成程序时，出现错误:
错误C2440:类型转换":无法从重载函数"转换为"FONTENUMPROC"
我不明白发生了什么.请帮帮我！
