怎么复制文件到局域网中另一台机器（急）

如何复制文件到局域网中另一台机器（急，在线等！）
知道该机器的ip和用户名，密码，还有共享的文件名

如何复制文件过去啊？

比如目标机器 ip:192.168.1.99 用户名:admin 密码：123。在cb中如何点一个按钮来完成这个功能？

谢谢

NETRESOURCE nr;
TCHARszUserName[32] = "user",     //遠端用戶名
       szPassword[32] = "password",       //密碼
       szLocalName[32] = "Q:",           //映射路徑
       szRemoteName[MAX_PATH] = "\\\\192.168.XXX.XXX\\Share"; //遠端路徑


//使用以下方式映射遠端到指定的盤符.
DWORD res;
nr.dwType = RESOURCETYPE_ANY;
nr.lpLocalName = szLocalName;
nr.lpRemoteName = szRemoteName;
nr.lpProvider = NULL;
res = WNetAddConnection2(&nr, szPassword, szUserName, FALSE);
if(res == NO_ERROR)
;
else
ShowMessage("連接到網絡失敗.");



//解除映射
WNetCancelConnection2(szLocalName, 0, True);
