使用TWinSocketStream::Read的时候Read error 64,请问是什么原因？

[zuoyefeng]

使用TWinSocketStream::Read时报错 Read error 64指定的网络名不再可用
代码如下，请问是什么原因，该如何解决
if (pStream->WaitForData(60000))
{ //if10
if(!ClientSocket->Connected)
{
Terminate();
return;
}

Sleep(2500);
recvlen = pStream->Read(recv_buf, 1024);

[zuoyefeng]

recvlen = pStream->Read(recv_buf, 1024);
在这里就出错了
真是奇怪

另外与Sleep(2500);没关系

WaitForData(60000));就是等待
Sleep(2500);这个可以不要。

The following example shows a typical ClientExecute method for a custom descendant of TServerClientThread. It reads from the socket connection specified by ClientSocket using a thread-local instance of TWinSocketStream.

void __fastcall TMyServerThread::ClientExecute(void)

{
TWinSocketStream *pStream;
char Buffer[10];
// make sure connection is active
while (!Terminated && ClientSocket->Connected)
{
try
{
Stream = new TWinSocketStream(ClientSocket, 60000);
try
{
memset(Buffer, 0, 10); // initialize the buffer
// give the client 60 seconds to start writing
if (pStream->WaitForData(60000))
{
if pStream->Read(Buffer, 10) == 0) // if can抰 read in 60 seconds

ClientSocket->Close(); // close the connection
// now process the request
...
}
else
ClientSocket->Close(); // if client doesn抰 start, close
}
__finally
{
delete pStream;
}
}
catch (Exception &E)
{
HandleException();
}
}
}

我也遇到过同样问题,后来发现帮助里面有一个模型,按照他那个模型就对了,我理解TWinSocketStream这个东西是在一次通信那么就建立一个，用完就delete了，这样看来效率不是很高啊，不过只得这样用了，不然就自己用winsocket函数

ErrorCode=64,其实就是网络连接已断开.
