GetLast returns zero error, if we click on repeat in the ASSERT file then it leads from main project to sockcore.cpp

BOOL CAsyncSocket::Accept(CAsyncSocket& rConnectedSocket,
SOCKADDR* lpSockAddr, int* lpSockAddrLen)
{
It points over her----->ASSERT(rConnectedSocket.m_hSocket == INVALID_SOCKET);
ASSERT(CAsyncSocket::FromHandle(INVALID_SOCKET) == NULL);

CAsyncSocket::AttachHandle(INVALID_SOCKET, &rConnectedSocket);
if (CAsyncSocket::FromHandle(INVALID_SOCKET) == NULL)
{
// AttachHandle Call has failed
return FALSE;
}

SOCKET hTemp = accept(m_hSocket, lpSockAddr, lpSockAddrLen);

hi, ASSERT is due to the WSA ERROR 10035,
Operation is blocked for non blocking operations, But how can I eleiminate this error?

while debugging I found that i have a problem with Accept function of the Socket.
I have attached the code below:

//Bind
m_sListener.Bind(6000);

//Listen
if (m_sListener.Listen() == FALSE)
{
AfxMessageBox(L"Unable to Listen on that port,please try another port");
m_sListener.Close();
return;
}
else
m_sListener.Listen(1);

//Accept
if (m_sListener.Accept(m_sConnected))
{
AfxMessageBox(L"TCP Connection accepted");

}
else
{
AfxMessageBox(L"TCP Connection not accepted");
}


Also in the OnInitialDialog()

void MESSDlg:: OnInitialDialog()
{


//Create
m_sListener.Create(6000);
}
while Debugging I have a ASSERT over the Accept function
and I am not able to figure out what is wrong in it.

TCPSocket is a class I have declared from CAsyncSocket
# pragma once
#include "pch.h"
#include "TcpSendSocket.h"
#include "MESS_TRIALDlg.h"
#include "DataFile.h"



TcpSendSocket::TcpSendSocket()
{
//UpdateData(TRUE);


}


TcpSendSocket::~TcpSendSocket()
{
}

But i need to sendthe data through tCP.
In UDP i used just rec() and create () .
In TCP listen(), bind(), accept(), Send().
But i think till listen() its working .
have some problems with accept(), I think, but I amnot sure.

the program is functioning I am able to receive data but not able to send data, Cannot find any errors!
Thats why I a m confused

I already did the way you mentioned and thats why i posted here!
Also I am new in to programming.

Actually my project is dealing with UDP and TCP Sockets.
Via UDP communication UDP packet is received , and then some editing is done and this packet is send via TCP.
But the TCP packets are not send!
this all process is done using multithread processing

Hi, I tried doing with many examples, but my packet is not send!

Hai CPallini
Thankyou for the suggestion.
my program works perfectly:):)

Yes thats the issue But i am not able to figure it out

i have created just a single socket objec

m_clientSocket.Create(7000, SOCK_DGRAM, FD_READ, NULL);
if (m_clientSocket.Connect(L"172.16.2.91", m_UDP_Port))
{
AfxMessageBox(L"Connection Successfull");
return;
}
else
{
AfxMessageBox(L"Connection Failed");
}
DWORD error = GetLastError();
This is the code before that,
Assert fucntion shows a error near the create and send fucntions in the program

Thanks!!

In my project, I would like to measure the continuous data form the UDP packet

Yeah , thanks for the suggestion!
I tried doing it many ways form internet.The main problem is I am not able to receive a continuosus udp packet. The programm stops after reciving one data packet
