ftp方式上传文件，不成功，高人帮我看看。

[guguqiaqia]

代码如下：

 HINTERNET hInternet = ::InternetOpen(L"Microsoft Internet Explorer",   
	                                INTERNET_OPEN_TYPE_DIRECT, 
                                    NULL,   
                                    NULL,  
                                    INTERNET_INVALID_PORT_NUMBER);
				 
				 if(hInternet == 0)
				 {					 
					 dwGetLastError = ::GetLastError();
					 //break;
				 }
				HINTERNET hInternetConnect = ::InternetConnect(hInternet, 
					                                           L"ftp://demo.test.net/",
															   INTERNET_DEFAULT_FTP_PORT,
															   L"demo",
															   L"demo",
															   INTERNET_SERVICE_FTP, 
															   0,
															   0); // 这一步总是连接不上。请问是怎么回事？
				 if(hInternetConnect==0)
				 {
					 dwGetLastError = ::GetLastError();
					 //break;
				 } 
				

				if(::FtpPutFile(hInternetConnect,g_strImageFileName,L"newfile.jpg",INTERNET_FLAG_TRANSFER_BINARY,0))
				{
					::MessageBox(NULL,L"上传成功！",L"提示",MB_OK);

				}else
				{
					::MessageBox(NULL,L"上传失败！",L"提示",MB_OK);
				}				 

				 ::InternetCloseHandle(hInternet);
				 ::InternetCloseHandle(hInternetConnect);	

如果哪位朋友有ftp上传文件的代码，请麻烦指导一下。谢谢。

692224 bytes sent.
The following was returned by the server:

Finished.

[guguqiaqia]

先非常感谢楼上。

回头立即试验您提供的代码。

[guguqiaqia]

对了，我需要连接远方的一个FTP网址，我问一下 strServerIP 这个值我需要连接到一个是 类似ftp://demo.hosttest.test.net 的地址。把这个ftp://demo.hosttest.test.net这么直接赋值给strServerIP 可以吧？

[guguqiaqia]

请问 “错误信息，和FTP服务器的链接被重置”这个问题该怎么解决？

在我的那个代码中该怎么修改呢。

[贪玩的老鼠]

DWORD dwGetLastError;
HINTERNET hInternet = ::InternetOpen("Microsoft Internet Explorer",
INTERNET_OPEN_TYPE_DIRECT,
"FTP",
NULL,
INTERNET_INVALID_PORT_NUMBER);

if(hInternet == 0)
{
dwGetLastError = ::GetLastError();
//break;
}
HINTERNET hInternetConnect = ::InternetConnect(hInternet,
"192.168.8.7",
INTERNET_DEFAULT_FTP_PORT,
"wtgl",
"altrust",
INTERNET_SERVICE_FTP,
INTERNET_FLAG_ASYNC,
0); // 这一步总是连接不上。请问是怎么回事？
if(hInternetConnect==0)
{
dwGetLastError = ::GetLastError();
//break;
}

[guguqiaqia]

先谢谢楼上的朋友。
这句话，我按照你的方式改了。如下。
HINTERNET hInternetConnect = ::InternetConnect(hInternet, L"ftp://demo.host1.sinodns.net/",
INTERNET_DEFAULT_FTP_PORT,
L"demo",
L"demo",
INTERNET_SERVICE_FTP,
INTERNET_FLAG_ASYNC,
0);

可是返回的错误代码是12007.

麻烦你试验一下，可以通过吗？

[贪玩的老鼠]

我的通过了,
你不要加ftp://

[贪玩的老鼠]

ftp://demo.host1.sinodns.net
改成demo.host1.sinodns.net

[guguqiaqia]

问题自我解决了。
