Hi,
I design one udp application in which application can receive infinite data from server and store that in text file,but problem is that packets are shown in wire shark with checksum but not received in application side. So my question is recvfrom api in vc++ reject that packets or some extra parameters should initialise before bind socket to application?

Is the checksum part of the actual data sent by the server?

yes!and so that packets are rejected by api?

That makes no sense, the send and receive functions transmit the data "as is", without adding or removing anything. you need to look more closely at your code.

I would suggest you read http://msdn.microsoft.com/en-us/library/windows/desktop/ms740120(v=vs.85).aspx[^], with particular reference to the handling of UDP messages.
