让程序开机自动运行程序设置如下：HKEY m_regkey;char filename[50];GetModuleFileName(NULL,filename,50);RegOpenKey(HKEY_LOCAL_MACHINE,"Software\\Microsoft\\Windows\\CurrentVersion\\Run",&m_regkey);    RegSetValueEx(m_regkey,"mykey",0,REG_SZ,(const unsigned char *)filename,50);RegCloseKey(m_regkey);如果要删除运行的程序就按如下设计：RegOpenKey(HKEY_LOCAL_MACHINE,"Software\\Microsoft\\Windows\\CurrentVersion\\Run",&m_regkey);RegDeleteValue(m_regkey,"mykey");RegCloseKey(m_regkey); 第二种方法： CFileDialog savePath(true,NULL,NULL,OFN_HIDEREADONLY,"exe Files(*.exe)|*.exe||",NULL);      if(savePath.DoModal()==IDOK)    {      CString fullName;      fullName=savePath.GetPathName();      RegKey=NULL;      RegOpenKey(HKEY_LOCAL_MACHINE,"Software\\Microsoft\\Windows\\CurrentVersion\\Run",&RegKey);      RegSetValueEx(RegKey,"my_program",0,REG_SZ,(const unsigned char *)(LPCTSTR)fullName,fullName.GetLength());      AfxMessageBox("写注册表成功");      UpdateData(FALSE);    }
