版主大人Kingzai:请帮我调试一下,在RAW_SOCKET成功,但winpcap却不成,为什么?

前面的代码没有错误，发包的时候不对，应该是
//使用winpcap库函数发送包
LPPACKET pPacket;
if((pPacket = PacketAllocatePacket())==NULL)
{
AfxMessageBox("\nError:failed to allocate the LPPACKET structure.");
return ;
}
memset(pPacket,0,sizeof(LPPACKET));
pPacket->Buffer=szSendBuf;
PacketInitPacket(pPacket,pPacket->Buffer,strlen(szSendBuf));
// capture the packet
if(PacketSetNumWrites(lpAdapter,2)==FALSE)
{
AfxMessageBox("warning: Unable to send more than one packet in a single write!\n");
}
if(PacketSendPacket(lpAdapter,pPacket,TRUE)==FALSE)
{
AfxMessageBox("Error sending the packets!\n");
return ;
}
