发送程序如下:
void SendFile()
{
#define PORT 34000 /// Select any free port you wish
AfxSocketInit(NULL);
CSocket sockSrvr;
sockSrvr.Create(PORT); // Creates our server socket
sockSrvr.Listen(); // Start listening for the client at PORT
CSocket sockRecv;
sockSrvr.Accept(sockRecv); // Use another CSocket to accept the connection
CFile myFile;
myFile.Open("C:\\test.doc", CFile::modeRead | CFile::typeBinary);
int myFileLength = myFile.GetLength(); // Going to send the correct File Size
sockRecv.Send(&myFileLength, 4); // 4 bytes long
byte* data = new byte[myFileLength];
myFile.Read(data, myFileLength);
sockRecv.Send(data, myFileLength); //Send the whole thing now
myFile.Close();
delete data;
sockRecv.Close();
}
接收程序如下:
void GetFile()
{
#define PORT 34000
AfxSocketInit(NULL);
CSocket sockClient;
sockClient.Create();
sockClient.Connect("192.168.87.202", PORT);
int dataLength;
sockClient.Receive(&dataLength, 4); //Now we get the File Size first
byte* data = new byte[dataLength];
sockClient.Receive(data, dataLength); //Get the whole thing
CFile destFile("c:\\test1.doc",CFile::modeCreate | CFile::modeWrite | CFile::typeBinary);
destFile.Write(data, dataLength); // Write it
destFile.Close();
delete data;
sockClient.Close();
}
程序可以运行,但是生成的test1.doc打不开,用UltraEdit打开,发现和test.doc不一样,不知这是怎么回事?
