WM_TIMER 消息
void CTimerTestDlg::OnTimer(UINT_PTR nIDEvent)
{
// TODO: Add your message handler code here and/or call default

CDialog::OnTimer(nIDEvent);
}

void CPage1::OnTimer(UINT nIDEvent)
{

}
两个都是继承自CDialog,为什么添加WM_TIMER的两个消息响应函数不一样呢?

[解决办法]
#if defined(_WIN64)
typedef unsigned __int64 UINT_PTR;
#else
typedef unsigned int UINT_PTR;
#endif
