改多线程有点累

只有单的

如果有谁有麻烦给我个，谢谢了~~~~~~~~~~~[e-mail]

BCB断点续传和多线程下载 可以不?给分吧

简单的文件传输，参考一下！
void __fastcall TFm_paper_cast::Button1Click(TObject *Sender)
{
if (OpenDialog1->Execute())
{
TFileStream *MyFStream;
MyFStream = new TFileStream(OpenDialog1->FileName, fmOpenRead);
try
{
NMStrm1->Host = "172.16.255.255";
NMStrm1->FromName = "cat";
NMStrm1->PostIt(MyFStream);
}
catch(...)
{
}
MyFStream->Free();
}
}

void __fastcall TFm_paper_cast::NMStrmServ1MSG(TComponent *Sender,
const AnsiString sFrom, TStream *strm)
{
if (FileExists("f:\copy.txt"))
DeleteFile("f:\copy.txt");
TFileStream *MyFStream;
MyFStream = new TFileStream("f:\copy.txt", fmCreate);
try
{
MyFStream->CopyFrom(strm, strm->Size);
}
catch(...)
{
}
MyFStream->Free();
}

多线程bcb的没有见过

收藏！！

不一定要多线程 你可以利用handle 单对多一样搞定 Pasp(CJY) 那个你可以看看

下面是我写的UDP例子，支持多线程！
你可以在每个线程使用这个对象实例，或多线程使用一个实例！
class XBroadcast
{
public:
XBroadcast();
virtual ~XBroadcast();
void Msg(const char * lpzRemoteHost, int iPort,const void * pBuffer,int iBufferSize);
void Msg(int iPort,const void * pBuffer,int iBufferSize);
void Msg(const char * lpzRemoteHost, int iPort,const XByteBuffer * Buffer );
void Msg(int iPort,const XByteBuffer * Buffer );
private:
TNMUDP * m_UDP;
XDynamicArray<AnsiString> m_IPArray;
TCriticalSection * m_SyncFlag;
};

//------------------------------------------------------------------------------
XBroadcast::XBroadcast()
{
m_UDP = new TNMUDP(NULL);
m_SyncFlag = new TCriticalSection();

unsigned long lBufLen;
unsigned long iIP;
unsigned long iMask;
unsigned long iBroadcastIP;
IP_ADAPTER_INFO *pAdapterInfo;
int IpCount = 0;
GetAdaptersInfo(NULL, &lBufLen);
IpCount = lBufLen/sizeof(IP_ADAPTER_INFO);
if( (lBufLen%sizeof(IP_ADAPTER_INFO)) != 0 ) IpCount++;
pAdapterInfo = new IP_ADAPTER_INFO[IpCount];
memset( pAdapterInfo, 0, sizeof(IP_ADAPTER_INFO) * IpCount );
try
{
if(GetAdaptersInfo(pAdapterInfo, &lBufLen)==NO_ERROR)
{
IP_ADAPTER_INFO *p = pAdapterInfo;

for(int i=0;i<IpCount;i++,p++)
{
iIP = 0;
iMask = 0;
iBroadcastIP = 0;
iIP = inet_addr(p->IpAddressList.IpAddress.String);
iMask = inet_addr(p->IpAddressList.IpMask.String);
iBroadcastIP = (~iMask) | iIP;
in_addr tmpIP;
tmpIP.S_un.S_addr = iBroadcastIP;
m_IPArray.Append(inet_ntoa(tmpIP));
}
}
}
__finally
{
delete[] pAdapterInfo;
}
}
XBroadcast::~XBroadcast()
{
m_SyncFlag->Enter();
m_SyncFlag->Leave();
delete m_UDP;
delete m_SyncFlag;
}
void XBroadcast::Msg(const char * lpzRemoteHost, int iPort,const void * pBuffer,int iBufferSize)
{
m_SyncFlag->Enter();
try
{
m_UDP->RemoteHost = lpzRemoteHost;
m_UDP->RemotePort = iPort;
m_UDP->SendBuffer((char *)pBuffer,iBufferSize,iBufferSize);
}
__finally
{
m_SyncFlag->Leave();
}
}
void XBroadcast::Msg(int iPort,const void * pBuffer,int iBufferSize)
{
int iLen = m_IPArray.Length;
for(int i=0;i<iLen;i++)
{
Msg(m_IPArray[i].c_str(),iPort,pBuffer,iBufferSize);
}
}
void XBroadcast::Msg(const char * lpzRemoteHost, int iPort,const XByteBuffer * Buffer )
{
Msg(lpzRemoteHost,iPort,Buffer->Data(),Buffer->Length);
}
void XBroadcast::Msg(int iPort,const XByteBuffer * Buffer )
{
Msg(iPort,Buffer->Data(),Buffer->Length);
}
