为什么在 if(lparam == 1) { g_strUser=m_strUser; g_strPsd=m_strPsd; g_strServer=m_strServer; dlg.m_message = "正在连接邮箱服务器，\n请稍后……"; dlg.DoModal(); } 之后就直接调到了错误提示，@jimoguilai DoModal（）；之后就显示错误，这是为什么啊？

我现在找到错午在哪里了 ，问题解决了 散分啦 ，要分的快来啊！

这个还不好调试？ CMyProgressDlg dlg;dlg.DoModal()出现问题，确认CMyProgressDlg的字符串支持\n?去掉字符试试、去掉\n试试？
