//通过调用控件对应的虹膜识别函数来实现虹膜识别的功能
m_ctrlBIO.BioIDMatchIris(IrisTemplatesDatabase,IrisDatabaseSize, Mode,Sleep);
}
我这边现在可以判断的是采集的虹膜信息是没问题的，我把从数据库里面读出来的虹膜信息替换了厂家提供的软件下根目录里的采集的虹膜特征文件，这个时候可以正常识别的。
下面这个是识别函数对应的消息事件响应
void CTestBioDlg::BioIDMatchIrisEvent(long RecordID, long MatchResult)
{
// TODO: Add your control notification handler code here
if (MatchResult == 1)
{
CString strMsg;
//匹配员工编号
matchID = m_strArrayWorkerNo[RecordID];
strMsg = "员工工号为【" + matchID + "】,识别成功!";
MessageBox(strMsg, "提示", MB_ICONINFORMATION | MB_OK);
::GlobalFree(p);
m_bDialogMode = TRUE;
// int nResponse = m_dlgexam.DoModal();
m_dlgexam.DoModal();
}
}
已经困扰了很久，求大神帮忙解答
