C++ (Cpp) StartRecvFile Examples

Example #1

File: recvdlg.cpp Project: dinodragon/mygooglecode

BOOL TRecvDlg::ConnectRecvFile(void)
{
	memset(fileObj->conInfo, 0, sizeof(ConnectInfo));
	fileObj->conInfo->addr = msg.hostSub.addr;
	fileObj->conInfo->port = msg.hostSub.portNo;

	if (msgMng->Connect(hWnd, fileObj->conInfo) != TRUE)
		return	FALSE;

	if (fileObj->conInfo->complete)
		StartRecvFile();

	return	TRUE;
}

Example #2

File: recvdlg.cpp Project: dinodragon/mygooglecode

BOOL TRecvDlg::TcpEvent(SOCKET sd, LPARAM lParam)
{
	if (fileObj == NULL || fileObj->conInfo == NULL)
		return	FALSE;

	switch (LOWORD(lParam)) {
	case FD_CONNECT:	// connect done
		StartRecvFile();
		break;

	case FD_CLOSE:
		EndRecvFile();
		break;
	}
	return	TRUE;
}

Example #3

File: PRJ3_0613Dlg.cpp Project: gomeansai/network-programming1

//函数：接收文件套接字
//功能：在客户端向服务器请求下载或上传之后，服务器会主动与客户机连接，该函数即处理该连接的建立
//
