[半吊子全栈工匠]

cmnet没问题，cmwap好像要做proxy设置吧

[文斌]

CMWAP得设置代理服务器，比如
m_hRoot=InternetOpen(L"agent",INTERNET_OPEN_TYPE_PROXY ,GetProxyIP(),NULL,INTERNET_FLAG_DONT_CACHE);

调用方法
Kostech.Net.FTP myftp = new Kostech.Net.FTP("", "wwwroot", "用户名", "mima", 21);
//myftp.Put("\\Program Files\\4.wav");
咋就不行
还把ftp服务器当掉了!

继续关注 等待下文

[sxlufo]

谢谢，大家 早就好了，就是可恶的电信竟然2台电脑同时上网连接失败，pda用数据线连接
电脑，竟然不可以上网了，直接用wifi或gprs就可以了！
以上的代码就可以，只是把 char ch = Char.Parse(ipData.Substring(i,1));
修改为 char ch = Convert.ToChar(ipData.Substring(i, 1)); 即可！
谢谢！

[sxlufo]

连接是cmnet 方式 就可以，没有其他的特别设置 ，直接使用即可
Kostech.Net.FTP myftp = new Kostech.Net.FTP("", "wwwroot", "用户名", "mima", 21);
myftp.Put("\\Program Files\\4.wav"); //上传文件

一个小经验，可供大家测试!
创建方式的另一方法
strP:程序所在路径
textBox1.Text=";

string tls = strP + "\\手机监控.lnk";
string tlnk;
if (System.IO.File.Exists(tls))
{
System.IO.File.Delete(tls);
} //没有快捷方式先创建 提示 这样创建的 必须是英文路径才可以

tlnk = textBox1.Text.Trim() + strP + "\\jk.exe" + textBox1.Text.Trim();
int tnum;
tnum = tlnk.Length+2;
tlnk = tnum.ToString() + "#" + tlnk;
System.IO.StreamWriter sw;
sw = new System.IO.StreamWriter(tls);
sw.Write(tlnk);
sw.Close();
这样就生成了程序的快捷方式！

不行啊，会报错，在：
int iBytes = socketControl.Receive(buffer, buffer.Length, 0);
错误是：现有连接被远程主机强行关闭
我是用的VS2005，和mobile6.0的模拟器，电脑操作系统是win7，FTP在本机，FTP本身访问正常、写入正常，可是用模拟器就会报错，暂未使用真机，是因为模拟器的原因吗？请高人帮忙！
