邮件地址判断,如下:

TCHARbuf1[12]={0};TCHARbuf2[12]={0};TCHARbuf3[12]={0};intret=swscanf_s(_T("abc2018@QQ.com"),_T("%[a-zA-B0-9]%*[@]%[a-zA-Z]%*[.]%s"),buf1,12,buf2,12,buf3,12);TRACE(_T("ret=%d:%s%s%s\n"),ret,buf1,buf2,buf3);if(ret==3)TRACE(_T("正确的邮件地址"));elseTRACE(_T("不正确的邮件地址"));

取出串口号后的数字,如下:

CStringstrCOM=_T("COM12");TCHARbuff[10]={};swscanf_s(strCOM,_T("%*[a-zA-Z]%[0-9]"),buff,10);TRACE(_T("%s\n"),buff);
